Elevation plate , and any components attached to the elevation plate such as a motor, as will be discussed below , may have significant weight and therefore it may be difficult to turn hand wheel to raise the blade. Accordingly, the depicted embodiment includes a gas spring mounted at one end to the elevation plate and at the other end to a bracket mounted to the front trunnion, as shown best in FIGS.

The gas spring is biased to push the elevation plate up with a predetermined amount of force to make it easy for a user to turn hand wheel to raise the blade. The force of the gas spring may be selected so that the elevation plate is biased up or down to take out any play or slack between threaded shaft and threaded bore Forces in the range of 50 to pounds may be used, depending on how much weight must be lifted.

It is important that elevation plate be restricted from any side-to-side motion or rotation around the longitudinal axis of support shaft in order to hold the saw blade straight, and support shaft and threaded shaft limit how the elevation plate may move. However, in the depicted embodiment, because the elevation plate is relatively long and supported principally at one end, and also because of manufacturing tolerances in shafts and and their corresponding bores in the elevation plate, there is a risk that the elevation plate may move slightly in an undesired manner, especially if the elevation plate is tilted.

Accordingly, elevation plate includes bores and in two projections at the distal end of the elevation plate, opposite bores and , and a guide shaft is mounted in the bores. The guide shaft may be held in the bores by clips, bolts, or any other method.

A guide block is placed on the guide shaft between bores and so the shaft can move up and down in the guide block. The guide block, in turn, is mounted to the apex of a V-bracket , and the opposite two ends of the V-bracket are bolted to the rear trunnion , as shown in FIGS. This arrangement allows the elevation plate to move up and down to change the elevation of the blade, but prevents the distal end of the elevation plate from moving to the side or rotating around shaft because the V-bracket is bolted to the rear trunnion and the guide block is mounted to the V-bracket.

This arrangement also accommodates variances or tolerances in manufacturing. Guide shaft should be substantially parallel with support shaft so that the elevation plate can move up and down on shaft without binding on shaft However, it may be difficult to make shaft substantially parallel with shaft , especially given that the shafts are spaced a significant distance apart.

In the depicted embodiment, guide shaft may be mounted in an eccentric bushing Bushing is similar to bushing shown in FIG.

Bushing has an off-center hole through which guide shaft passes. The bushing is placed over the shaft and in bore and held on the shaft by a clip. The bushing may then be turned to move the guide shaft and align the shaft as necessary.

When the bushing is turned to its desired location, it is held in place by a set screw shown in FIG. Guide block is bolted onto the apex of V-bracket , as explained. A single bolt mounts the guide block to the V-bracket so the bracket can be adjusted or rotated around the bolt to align with the guide shaft so the guide shaft can slide up and down in the guide block.

The two ends of V-bracket opposite the guide block are bolted to the rear trunnion by bolts , as stated. The V-bracket itself is made of a material which has some flex, such as metal, and there is a distance between bolts and guide block That distance and the flex of the material allow the V-bracket to flex out toward the rear of the saw if necessary to accommodate the guide shaft. That flex may be necessary if the distance of shaft from shaft , the position of shaft or shaft in the saw, or the dimension of other components in the saw varies due to manufacturing tolerances or other reasons.

That flex also may be necessary to accommodate the expanding or contracting of the elevation plate due to temperature changes. Thus, the ability of the V-bracket to flex out helps prevent the guide shaft from binding in guide block This mounting configuration may be thought of as constraining only one degree of freedom of the guide shaft; specifically, it constrains any side-to-side movement of the guide shaft. The mounting configuration allows the guide shaft and elevation plate to move up and down and front-to-back.

This mounting configuration accommodates some misalignment of the guide shaft. An arbor block is pivotally mounted to the elevation plate as shown in FIGS. The arbor block includes two projections and , each projection having a bore , as shown in FIG. The elevation plate includes a raised portion and bore extends through that raised portion, as shown in FIG. Projections and on the arbor block sandwich raised portion , and a shaft then passes through bores in the arbor block and bore in the elevation plate to mount the arbor block to the elevation plate.

Arbor block may then pivot up and down around shaft An arbor is mounted for rotation in arbor block , as shown in FIGS. The arbor is held in two bearings that are mounted in bearing seats in the arbor block. The bearings are isolated electrically from the arbor block by plastic overmolding on the arbor or by insulating bushings.

Electrodes are positioned adjacent but not touching the arbor to impart the electrical signal to the blade used in the detection subsystem discussed above. The configuration of the arbor and electrodes are disclosed in detail in U. Shaft extends outwardly from the right side of the arbor block a sufficient distance so that a brake cartridge may be pivotally mounted on the shaft, as shown in FIG.

The brake cartridge is sized and positioned so that it is adjacent the perimeter of a blade having a specified nominal diameter.

The brake cartridge includes a pawl, and the pawl pivots toward the blade around shaft to stop the blade from spinning when the detection subsystem detects that a person has contacted the blade, as described above. The brake cartridge may be constructed and mounted in the saw in many ways. Examples of how the brake cartridge may be constructed and mounted in a saw are disclosed in U. That provisional patent application also discloses how the position of the brake cartridge relative to the perimeter of the blade may be adjusted by a linkage between the arbor block and the mounting structure for the brake cartridge.

Arbor block includes an aperture through which a bolt may extend to adjust the spacing between the brake cartridge and the blade. Brake cartridge also acts as a mechanism to prevent a user of the saw from installing a blade larger than recommended. The brake cartridge physically blocks a large blade from being mounted on the arbor because the blade bumps into the brake cartridge. Arbor includes a pin labeled in FIG.

Pin and arbor block support mechanism also provide rigidity to the arbor block and minimize any vibration of the arbor block during normal operation of the saw. However, when a person accidentally contacts the blade the brake cartridge will engage and stop the blade.

The angular momentum of the blade as it is stopped will create a significant downward force and that force will cause pin to disengage from the arbor block support mechanism. When the pin has disengaged, the arbor block will be free to pivot around shaft , so the downward force resulting from stopping the blade will cause the arbor block to pivot down very quickly.

The blade will also pivot down because the blade is supported by the arbor block. In this manner, the blade will retract below the tabletop of the saw when a person accidentally contacts the blade. The arbor block support mechanism is shown in detail in FIGS. An L-shaped bracket is bolted onto surface on the elevation plate surface is labeled in FIG. The L-shaped bracket includes a projection having a first surface and a second surface The first and second surfaces define a corner region into which pin would normally nest.

Material from projection may be removed in the corner region to allow pin to contact first and second surfaces and at points that are somewhat distant from each other to better hold the pin.

A small pivot arm is mounted on L-bracket so that the pivot arm may pivot around a bolt The pivot arm includes a tab having a support surface Support surface also abuts against pin to help hold the pin in place during normal operation of the saw. Pivot arm also includes a distal end shaped to include an aperture through which a shoulder bolt may pass. The shoulder bolt passes through distal end and threads into projection in the L-shaped bracket.

A spring and washer are positioned between the head of bolt and distal end of the pivot arm. The spring is sized to bias the pivot arm toward projection Thus, pin is held in corner by spring pushing pivot arm against the pin.

Threading bolt into or out of projection will adjust the force exerted by spring against pin When brake cartridge stops the blade, the downward force caused by the angular momentum of the blade will overcome the force of spring , and pin will then push pivot arm aside and move down. Projection includes a third surface that connects with but slopes away from second surface Third surface slopes away in order to provide clearance for pin to move down. As soon as pin moves down past the point where the third and second surfaces connect, the pin no longer contacts projection so it is free to move down.

Similarly, tab on pivot arm is rounded to quickly release pin when the pin begins to move down. The intersection of second surface with third surfaces is positioned substantially opposite the tangent point of the rounded tab so that pin is released from both projection and tab substantially simultaneously. A bumper or pad is mounted on trunnion brace below arbor block , as shown in FIGS. When the arbor block retracts, bumper stops the downward motion of the arbor block and helps absorb the energy of the retraction.

The arbor block includes a surface configured to contact bumper , as shown in FIGS. The energy of retraction may be significant. Accordingly, bumper may be selected from materials that have good dampening characteristics and arbor block may be made from a ductile iron so that the arbor block it is less likely to be damaged during retraction.

Additionally, trunnion brace should be constructed so that it is sufficiently strong to support bumper and withstand the force of impact with the arbor block. Trunnion brace and elevation plate are both construction to provide clearance for the arbor block and blade to retract in case of an accident. As shown in FIGS. Elevation plate also includes a recessed area labeled in FIG. Saw is powered by a motor mounted to the bottom of elevation plate The motor may be mounted to the elevation plate in many ways.

In the depicted embodiment, tabs projects up from the motor and sandwich a projection on the bottom of the elevation plate projection is labeled in FIGS.

Bolts and pass through holes in the tabs and projection to mount the motor to the elevation plate, as shown in FIGS.

A drive shaft extends from the motor and a pulley is mounted on the drive shaft. A double pulley is mounted on the left end of shaft so that a first belt not shown may extend around the motor pulley and the outside of the double pulley.

A third pulley is mounted on the left end of arbor and a second belt not shown extends around pulley and the inside of double pulley Motor turns pulley , which then turns double pulley and arbor pulley , causing the blade mounted on the arbor to spin. The depicted embodiment includes a double belt system as described so that arbor block may retract by pivoting down around shaft without disengaging from the drive belts. Pulleys and are fixed-center pulleys, so a slightly stretchy Poly-V belt designed for fixed center pulleys is used.

A slightly stretchy belt also has the advantage of being able to stretch and slip on pulley when the brake cartridge stops the blade. This is advantageous because pulley will stop very suddenly when the brake cartridge stops the blade, but the motor and belts will continue spinning for a short period of time. A stretchy belt will be able to stretch and slip on pulley when the pulley stops suddenly.

Of course, other belt and pulley configurations and belt tensioning systems may be used. The belt around pulley is preferably made of a static dissipative material so that static charge does not build up on the arbor or blade.

This is advantageous because in some implementations a static charge may interfere with the detection subsystem. A standard belt or a slightly stretchy belt may extend around motor pulley and the outside of double pulley The pulleys may be sized so that the blade spins at a desired speed, such as rpm, while the motor spins at a different speed, such as rpm. The belt extending around the motor pulley and the outside of double pulley may be tensioned by moving the motor out.

In the depicted embodiment, motor is mounted to the elevation plate so that it may pivot around bolt Tabs include an oversized hole through which bolt passes so that the motor may pivot around bolt To put tension on the belt, bolt is loosened and the motor is pivoted around bolt away from the double pulley. When the desired tension is achieved, bolt is tightened to hold the motor in position.

Trunnion brace is shaped to partially shroud the blade under table Shrouding the blade prevents a person from contacting the blade under the table. This is useful because if a person contacts the blade under the table, the brake cartridge will fire and the blade will retract, possibly into the person's hand.

Shrouding the blade also helps to collect sawdust created when the saw is running. Trunnion brace is shaped to create a trough or channel , shown in FIG. The trough is wide enough to shroud the blade and to allow a person to reach into the saw through opening in the tabletop to change either the blade or brake cartridge.

Trough is sloped down, as shown in FIGS. Preferably, the inside surface of the trough, including the bottom and side walls, is as smooth as possible to avoid trapping sawdust. A hose coupling is mounted to the bottom of the trunnion brace over port The coupling includes a mesh sized to prevent the bolt and washer with which the blade is secured to the arbor from falling through the mesh. It is possible when a user changes the blade that the blade nut or washer could fall into the saw and become difficult to retrieve.

Mesh prevents the bolt or washer from falling where they would be difficult to retrieve. A flexible vacuum hose or other conduit not shown is connected to the bottom of the coupling and extends to a similar port on the back of the saw. Thus, sawdust is collected by the blade shroud and then directed out through port and through a conduit to the back of the saw.

A user may connect a vacuum system to the port on the back of the saw to collect the sawdust and to create an airflow from the blade shroud to the back of the saw. The hose or conduit between coupling and the port on the back of the saw is flexible so it can move when the trunnion brace tilts.

A side blade shroud , shown in FIGS. This shroud further encloses the blade to prevent inadvertent contact with the blade and to collect sawdust. Side shroud is mounted to the trunnion brace by a vertical hinge The vertical hinge allows the side shroud to pivot out, away from the blade, around the vertical axis of the hinge.

Pivoting the side blade shroud out provides additional room to change the blade or brake cartridge. The additional room is especially necessary to slide brake cartridge off of shaft The side shroud includes magnets to engage the rear trunnion and hold the side shroud closed, although other mechanisms may be used to hold the side shroud closed. The top of the side shroud is shaped and positioned sufficiently away from the underside of the tabletop so that the blade can tilt to the left without the side shroud bumping into the underside of the table.

A front shroud is also mounted on the trunnion brace to the front of the blade. This shroud further helps enclose the blade and direct sawdust to the port in the bottom of the trunnion brace. The right side of this shroud is shorter than the left side in order to allow the blade and trunnion brace to tilt to the left.

This shroud would typically be made of a lightweight material to reduce the weight of the saw. Alternatively, the trunnion brace itself may be designed to extend up and form the front blade shroud. The underside of table may include recesses to allow the blade to rise to a predetermined height without the arbor block bumping into the underside of the table. The cabinet of the table saw may include in opening to allow access to the internal mechanism of the saw.

The cover is mounted to the cabinet with hinges so it can pivot open. A standard latch is used to keep the cover closed. The cover may include louvers to allow airflow into the cabinet.

Saw may also include a switch box with one or more switches to control the operation of the saw. A switch box designed for use with safety systems as described above is described in detail in U. Saw may also come with a fence that rests on table and clamps to a front rail. The fence provides a face against which a user may slide a work piece when making a cut.

One possible fence is disclosed in U. The saw may also come with a miter gauge and a blade wrench The riving knife is shown alone in FIGS. Riving knife is a flat, fin-like plate positioned in the saw adjacent the back edge of the blade. The riving knife is mounted in the saw within the projected kerf and top-to-bottom cutting capacity of the blade.

Thus, as a workpiece is cut by the blade, the riving knife will fit into the newly cut slot in the workpiece so that it does not block or impede the movement of the workpiece past the blade. Riving knife functions to prevent a workpiece from engaging the teeth at the back of the blade.

As a workpiece is cut into two sections, the newly cut sections may flex or move. If one of the newly cut sections moves to the side and catches the back edge of the spinning blade, the blade may suddenly kick the workpiece back toward the user at a very high speed and the user's hand may be pulled into the blade by the sudden movement of the workpiece.

The riving knife impedes the workpiece from moving to the side and thereby minimizes the chance of the workpiece catching the back edge of the blade. The riving knife also minimizes the chance of newly cut sections of a workpiece moving together and binding the blade.

The sides of the riving knife are parallel and the riving knife has a body thickness thinner than the kerf of the blade for which it is intended to be used. The body thickness, however, should not be substantially thinner than the kerf of the blade or the riving knife will be less able to impede a workpiece from catching the back edge of the blade.

Typically, the riving knife has a body thickness thicker than the body thickness of the blade but thinner than the kerf of the blade.

The riving knife includes a leading edge that is curved to follow the edge of whatever blade or blades are intended to be used with the riving knife. Leading edge includes a chamfer so that the edge does not catch on a workpiece as the workpiece is moved past the blade.

The riving knife also includes a tip rounded and chamfered so that it does not catch on a workpiece. The rounded tip often has a radius of not less than 0. The riving knife should be sufficiently rigid so as not to deflect or displace any significant distance toward the blade or to the side.

The riving knife is mounted in the saw close to the blade but not touching the blade. The radial distance between the leading edge and the back of the blade is typically at least 0. The highest point of the riving knife is typically at least 0. The riving knife is also mounted in the saw so that it remains in a fixed position relative to the blade as the blade tilts and changes elevation relative to the table.

In other words, the riving knife tilts and moves up and down with the blade. The riving knife may be used for most cuts performed on a table saw, including through-cuts where the blade cuts through the entire thickness of the workpiece and non-through-cuts where the blade does not cut through the entire thickness of the workpiece.

There are some cuts, however, where a riving knife may not be used, such as a plunge cut where the blade is raised up into a workpiece and a cove cut where the workpiece is moved past the blade at an angle relative to the plane of the blade so that the blade removes a groove or cove of material. In both those cuts, the riving knife would be outside the cut produced by the blade and would abut the workpiece.

Similarly, dado blades which are stacks of blades mounted on the saw to cut a groove in a workpiece are typically smaller in diameter than normal blades so riving knives designed for normal blades would extend above the dado could not be used because they would abut the workpiece. Dados are also substantially thicker than normal blades and therefore a riving knife designed for a single blade might not impede a workpiece from catching the back edge of a dado stack.

It is desirable for a user to be able to install and remove the riving knife quickly and easily when performing different operations with the saw so that the riving knife is not an inconvenience. For example, if a user needs to make both non-through and dado cuts, then the user will have to remove the riving knife before and re-install it after each dado cut.

If it were complicated, difficult or time consuming to remove and reinstall the riving knife between the different cutting operations, then it would be less likely a person would use the riving knife. The table saw shown in FIGS. Mounting system is shown isolated in FIGS. Mounting system includes a mounting plate that is bolted onto raised portion of elevation plate by bolts , as shown in FIG.

Raised portion is also shown in FIGS. Mounting plate is shown isolated from other structure in FIGS. Mounting plate includes a flat bottom surface that rests on raised portion of the elevation plate. Two holes pass through the mounting plate and bolts extend through those holes and are threaded into corresponding holes on raised portion Holes are oversized relative to bolts so that the position of the mounting plate may be adjusted relative to the elevation plate.

By adjusting the position of the mounting plate, the position of the riving knife relative to the blade may be adjusted, as will be explained below. Mounting plate also includes a flat face and two holes that pass through the face. A positioning plate is bolted onto face of mounting plate by bolts that pass through holes and are received into threaded holes Holes are oversized and oval shaped so that the position of plate may be adjusted. Positioning plate is shown isolated in FIGS.

Positioning plate functions to position the riving knife in the mounting system. The positioning plate includes a flat surface to support one side of the riving knife and two pins that extend out from that flat surface, as shown.

The base of riving knife includes two holes and pins are configured to extend through those holes to locate the riving knife in the mounting system. The positioning plate also includes two flanges extending perpendicularly out from opposite edges of flat surface , and each flange includes a shoulder Riving knife includes corresponding edges and shoulders configured to position the riving knife between flanges and on shoulders against the positioning plate, as shown in FIG.

Thus, the riving knife is positioned in the mounting system by fitting on pins between flanges and on shoulders Mounting system also includes a clamping plate that works with positioning plate to clamp and hold the riving knife in position.

Clamping plate includes a flat surface that supports the side of the riving knife opposite the side supported by the positioning plate. Flat surface includes recesses that provide clearance for pins and for contaminants like sawdust so that the clamping plate can abut against the riving knife evenly.

The clamping plate also includes shoulders and edges that correspond to shoulders and flanges on the positioning plate so that the clamping plate fits between flanges as shown in FIG. Clamping plate also includes a hole through which a bolt passes. Bolt is labeled in FIG. Bolt passes through hole and is threaded into a hole in positioning plate to loosely connect the clamping plate to the positioning plate. A spring , shown in FIG.

Spring may be a compression spring, a wave compression spring or some other spring. Spring biases clamping plate away from positioning plate to help open the clamp, as will be described below. Clamping plate also includes a first set of cam surfaces and and a second set of cam surfaces and The cam surfaces are positioned in a recess that is concentric with hole and the cam surfaces are arcuately spaced around the hole, as shown.

Cam surfaces and slope up from the bottom of recess to where they join with cam surfaces and , respectively. In the depicted embodiment, each of cam surfaces and is a portion of a helix or coil with a pitch of Each of cam surfaces and is a portion of a helix or coil with a pitch of 1. Of course, other cam surfaces and pitches may be used. The cam surfaces are used to move clamping plate toward positioning plate , as will be explained. Mounting system also includes a cam bushing shown isolated in FIGS.

Cam bushing includes cam surfaces and joined by a first edge , and a second set of cam surfaces and joined by a second edge Those cam surfaces are arcuately spaced around a hole , as shown, and they are configured to correspond roughly with the cam surfaces in the clamping plate. In the depicted embodiment, each of cam surfaces and is a portion of a helix or coil with a pitch of 44 mm.

Each of cam surfaces and is a flat surface. Other cam surfaces and pitches may be used. Cam bushing also includes a flange to abut against the front of the clamping plate to limit the distance the bushing may extend into recess Cam bushing has an octagon-shaped drive head that can be gripped to turn the bushing and a point inner socket positioned in drive head , as shown in FIG.

Bolt passes through hole in the cam bushing and through hole in the clamping plate and then screws into hole in the positioning plate, as shown in FIG. The head of bolt may then fit into point inner socket Mounting system also includes a handle , shown in FIGS. Handle has an elongate body with an 8-facet socket at one end configured to fit over octagon-shaped drive head on cam bushing A set screw is threaded into a hole on the handle to hold the handle and the cam bushing together when socket is positioned over drive head The various components of mounting system described above may be made from various strong and hard materials, such as machined metal, powder metal or cast metal.

It is also possible that the components may be made from a hard plastic or thermoset. The cam bushing and handle may be combined into one single part. Mounting system may be thought of as having an open position where the clamping and positioning plates are spaced apart from each other and a closed position where the two plates are moved closer together. The open position is shown in FIGS. In that position, handle is raised and plates and are spaced apart.

The mounting system should be configured and adjusted so that in the open position plates and are spaced sufficiently far apart for the riving knife to be moved off of pins and removed from between the plates.

The closed position is shown in FIGS. In that position handle is lowered and plates and are closer together to clamp the riving knife and hold it in position. When handle is moved up to open the clamp, the handle turns cam bushing so that the cam bushing fits into recess on the clamping plate without engaging the cam surfaces.

In that position, spring pushes the clamping plate and cam bushing away from positioning plate until the cam bushing abuts the head of bolt and the clamping plate abuts the cam bushing. The distance the clamping plate may move away from the positioning plate can be adjusted by turning bolt Threading bolt into hole on the positioning plate lessens the distance the clamping plate may move out because it moves the bolt head and cam bushing closer to the clamping plate.

Threading the bolt out of hole increases the distance the clamping plate may move out. Bolt may be threaded in or out by pressing the clamping and positioning plates together and pressing the cam bushing into recess The head of bolt will then extend out beyond the cam bushing so that it may be gripped and turned by hand or with a wrench.

When the bolt is adjusted to its desired position, the cam bushing and plates are released and spring pushes them out until the cam bushing abuts the head of the bolt and the bolt head fits into socket in the cam bushing.

Socket is a point socket so that the bolt head can fit into the socket in many different positions and thereby allow fine adjustment of the distance bolt is threaded into hole Spring is sized and selected so that it is at least partially compressed even when the mounting system is in the open position. For example, the spring may be sized and selected so that it applies 5 to 15 pounds of force against the clamping plate in the open position, and more force when compressed.

In this manner, the spring biases the clamping plate out so that the mounting system opens when handle is raised. With mounting system in the open position, riving knife may be placed in the clamp with holes in the riving knife fitting around pins on the positioning plate and shoulders on the riving knife resting on shoulders of the positioning plate, as shown in FIG.

In this manner, the riving knife is positioned in the mounting system. The base of the riving knife includes a cut-out to provide clearance for bolt and spring Handle may then be moved down to clamp the riving knife between the positioning and clamping plates. Moving handle down causes cam bushing to turn. The cam surfaces are inclined somewhat steeply so that a relatively small rotation of the handle will cause a significant movement of the clamping plate toward the positioning plate.

Of course, other configurations and geometries are possible. When edges and move to the top of cam surfaces and , cam surfaces and on the cam bushing will engage cam surfaces and on the clamping plate. Continued downward rotation of the handle will then cause cam surfaces and to slide over cam surfaces and These cam surfaces are configured and sized so that when they engage, the cam bushing and clamping plate are stable, with little or no force tending to move the cam surfaces to unclamp the mounting system.

In other words, the geometry of the cam surfaces prevents vibration or other factors from causing the mounting system to unclamp or open. One possible configuration is to make cam surfaces , , and relatively flat and smooth with only very little or no slope. Of course, numerous configurations of the cam surfaces are possible and various slopes and shapes may be used depending on the desired movement and clamping action. As handle rotates down, bolt will unthread from hole and thereby loosen the clamping action.

However, as cam surfaces and slid over cam surfaces and the loosening of the bolt is more noticeable because those cam surfaces typically do not have a significant pitch. Alternatively, one set of cam surfaces may have a pitch slightly greater than the pitch of the threads on the bolt and the other set of cam surfaces may be flat. This is the configuration shown in the depicted embodiment, where the pitch of the threads on bolt is 1 mm, the pitch of cam surfaces and is 1.

This configuration tightens the clamp slightly more than the unthreading bolt loosens the clamp. As another alternative, those cam surfaces may incline slightly less than the pitch of the threads on the bolt so that the clamping action is slightly less than the loosening of the clamp by the unthreading of the bolt. In that configuration, the downward movement of the handle becomes slightly easier as the bolt unthreads. Handle also includes a shoulder shown in FIGS. Shoulder on the handle is adapted to abut against bolt as the handle rotates downward so that bolt acts as a stop to limit the rotation of the handle.

Without that stop, the handle could rotate downward until the cam bushing could again fit into recess and thereby allow the clamp to open. Numerous other stops are possible, including a stop integral with the clamping plate. When included in a saw, mounting system is accessible to a user of the saw through opening in the table, as shown in FIG. Typically, a throat plate or table insert would be positioned in opening , as shown in FIGS.

A user would simple remove the throat plate, reach through the opening, grasp handle , and move it up or down as required to install or remove the riving knife. Specifically, to install the riving knife a user would simply move handle up to open the mounting system, place the riving knife on the positioning plate, and then move the handle down to clamp the riving knife in place.

Handle includes a bend or step , labeled in FIG. Handle may be sized so that it is long enough to extend up through opening and above the tabletop when the mounting system is in the open position with the handle raised, even when the blade is set to its lowest elevation. By so doing, a user would be reminded before using the saw that the riving knife was not clamped into position because the handle would interfere with the throat plate.

The geometry of the handle and mounting system may also be configured so that when the handle is moved up, it remains up without falling back down due to gravity. Mounting system may be adjusted to accommodate riving knives of various thicknesses by adjusting bolt , as explained.

Threading bolt in or out also adjusts the amount of force applied during clamping. Mounting system is adapted so that the position of the riving knife relative to the blade may be adjusted. The side-to-side and front-to-back position of the riving knife, as well as the twisting or yaw of the riving knife relative to the blade, may be adjusted to make sure the riving knife is within the kerf of the blade and within the desired radial distance from the back edge of the blade by loosening bolts , moving the mounting system as necessary, and then re-tightening the bolts.

The elevation or height of the riving knife relative to the blade may be adjusted by loosening bolts , moving positioning plate up or down as necessary, and then re-tightening the bolts. The angle or slope of the riving knife toward or away from the back edge of the blade also may be adjusted by loosening bolts and pivoting positioning plate toward or away from the blade, although the amount plate can pivot will depend on the size of holes in mounting bracket and on the size of bolts Once the position of the mounting system relative to the blade has been set, the riving knife may be removed and re-installed repeatedly without having to re-adjust the position of the riving knife.

The riving knife will fit onto positioning plate and the clamping action of the mounting system will press the riving knife against surface of on the positioning plate, thereby locating the riving knife in the same position each time it is re-installed into the mounting system. A user may therefore remove the riving knife when necessary for a given operation and replace the riving knife quickly and easily without tools and without having to re-adjust the position of the riving knife.

The ability of the mounting system to position the riving knife accurately when it is re-installed may be thought of as indexing the riving knife to a predetermined position. As stated above, mounting system is mounted on portion of elevation plate Mounting the mounting system on the elevation plate means that the mounting system and riving knife will move up and down and tilt with the blade as the blade moves.

Thus, the position of the riving knife relative to the blade remains constant as the position of the blade relative to the table changes. Mounting system is constructed so that items other than a riving knife may be attached to or mounted in the saw. Any item that includes a base configured to fit over positioning plate and sized to be clamped between the positioning plate and clamping plate may be mounted and indexed in the saw as described. Blade guard assembly is another item that may be mounted and indexed in mounting system Blade guard is shown isolated in FIGS.

Blade guard includes a blade shroud shaped to fit over the blade and shield a person from accidentally contacting the blade. The shroud forms a cavity in which the blade may spin. The shroud is made from a nonconductive material such as polycarbonate or some other plastic so that the shroud will not affect any electrical signal on the blade if the shroud comes into contact with the blade and if the saw includes a contact detection system as described above.

In fact, blade guard is constructed so that no metal or conductive part of the guard can contact the blade. The material of the shroud should be sufficiently soft so that it will be unlikely to damage the blade if the shroud comes into contact with the blade.

Often shroud is made of a clear plastic so that the blade can be seen through the shroud and especially so that the cutting edge of the blade can be seen through the shroud by an operator of the saw. Shroud is made from two halves joined together by screws, nuts and bolts, sonic welding, adhesive, clips or some other method or it can be a single molded piece.

The bottom of each side of blade shroud includes a flat edge adapted to rest on tabletop when the blade is set at degrees relative to the table top. Alternatively, the bottom edge of one side may be raised slightly to accommodate when the blade tilts relative to the tabletop. The left bottom edge when facing the saw in the normal operating position would be raised for a left-tilting saw and the right bottom edge would be raised for a right-tilting saw.

In this configuration, if one bottom edge rests on the tabletop when the blade is set at degrees, the other bottom edge typically would rest on the tabletop when the blade is tilted to degrees. Blade shroud also includes a top edge shaped to curve closely around the blade. The top edge of the blade shroud follows closely to the curve of the blade when the blade is fully elevated in order to minimize the size of the shroud, to create a substantially smooth and curved inside surface for dust collection, and to present a pleasing appearance.

A front portion of the blade shroud extends up and out from the shroud, as shown, and may be thought of as a horn. Front portion extends up to provide a contact surface for a workpiece to abut as the workpiece moves toward the blade. When the workpiece abuts the front portion, the workpiece will push the guard up to allow the workpiece to slide under the guard and past the blade. Front portion is sized to accommodate the maximum cutting depth of the saw, which, for example, is often 3.

In other words, front portion is sized so that the thickest workpiece that can be cut on the saw will abut the surface and push the guard up. The front portion is angled so that the workpiece will not catch on the shroud when the workpiece moves toward the blade. A wall or barrier labeled in FIG. Bottom edges of the blade shroud also include inwardly projecting flanges , one on each side, as shown in FIGS.

Flanges also will abut the blade if the shroud deflects to the side, thereby protecting the shroud from the blade by minimizing the region over which the blade contacts the shroud. Blade shroud is also configured to fit closely to the sides of the blade, as shown in FIGS. A right side and a left side of the blade shroud are shown in those figures. The front of the blade shroud has a wider dimension than the rear because the blade shroud will have more play or side-to-side movement at the front than at the rear, as will be explained.

The right side of the blade shroud is configured as close to the blade as possible so that the fence of the table saw can be moved as close as possible to the blade before bumping into the guard. The right side of the blade shroud is flatter than the left side, as shown in FIG.

Configuring the shroud to be close to the sides of the blade, and particularly close to the right side of the blade, allows the guard to be used when the fence must be positioned close to the blade. The configuration of blade shroud described herein may be thought of as a low-profile configuration because the shroud fits closely around the blade.

This low-profile configuration reduces the degree that the blade guard interferes with the operation of the saw and is less obtrusive than other guards.

Making the blade guard and blade shroud as small and unobtrusive as possible increases the likelihood that the guard will be used and will not be removed by a user of the saw. The low-profile guard also minimizes the regions in which sawdust may collect and directs sawdust to a collection area below the tabletop of the saw.

Blade shroud is pivotally connected to a support arm Support arm is a folded metal arm with a U-shaped cross section, and is shown isolated in FIG. Support arm includes a first tab with a first hole and a second tab with a second hole Tabs and are adapted to fit over and around a designated portion of blade shroud Specifically, blade shroud includes a hole near the top edge of the shroud as shown in FIG.

Hole extends through a boss that spans the shroud from one side to the other. A steel pin extends through the holes to pivotally connect the blade shroud to the support arm.

Pin is shown in FIG. Pin includes a main section that is lightly press fit into hole in the blade shroud so that the pin is held snug and securely by the blade shroud so that there is no play between the blade shroud and the pin.

Main section of the pin has a diameter sized to fit securely into second hole in the support arm so that the pin can rotate in the hole with very little play. The end of pin that fits into hole is substantially flush with the outside surface of the support arm when the pin is positioned properly so as not to increase the side-to-side dimension of the overall blade guard.

Pin also includes a first recessed section and a second recessed section The change in diameter from main section to first recessed section creates a shoulder that abuts against the inside surface of tab on the support arm. The diameter of hole in tab is sized to accept first recessed portion so that the pin can rotate in the hole with very little play, but the diameter of hole is smaller than the diameter of main section In this manner, the position of shoulder defines the position of the pin in holes and The length of main section is substantially equal to the distance between the inside surface of tab and the outside surface of tab Second recessed portion is configured to receive a clip to hold the pin in place.

The pivot connection between blade shroud and support arm allows for a metal-to-metal pivot rather than a metal-to-plastic pivot because tabs and in the support arm contact pivot pin Having a metal-to-metal pivot connection permits the connection to be more precise than it otherwise could be because the metal components may be manufactured with smaller or tighter tolerances and because the metal-to-metal pivot connection will wear less than other connections.

This is important because a more precise pivot connection means there will be less play, vibration or side-to-side movement of the blade guard. Support arm is also designed to have a significant width or side-to-side dimension between tabs and That width provides stability for the blade shroud and minimizes the play, vibration, and side-to-side movement that could otherwise result. One possible width or side-to-side dimension of support arm is around 1. Making support arm relatively wide, however, means that the support arm is wider than the blade shroud.

Accordingly, left side of the blade shroud includes a raised portion so that the blade shroud fits and substantially fills the space between tabs and on the support arm, as shown in FIGS.

Raised portion also includes flat outside surfaces to minimize or eliminate any interference with the inside surfaces of tabs and on the support arm when the blade shroud pivots around pin Hole in the blade shroud passes through raised portion Typically, there would be some minimal clearance between the inside surfaces of the support arm and the outside surfaces of the blade shroud so there is no friction or drag between them when the shroud pivots. Alternatively, the size of raised portion and the resulting side-to-side dimension of the blade shroud can be selected to create a desired amount of friction between the blade shroud and the support arm so that a predetermined amount of force is required to pivot the blade shroud.

Tabs and on the support arm create an open region that provides clearance for the blade shroud to pivot. Open region is limited by edge and upper surface Blade shroud includes a projection that acts as a stop to limit the counterclockwise rotation of the blade shroud when viewed as in FIG.

Projection includes a curved surface and a tab extends out from surface Projection is sized so that curved surface slides past edge in the support arm when the blade shroud pivots, but tab abuts upper surface on the support arm when a predetermined amount of rotation has occurred.

The clockwise rotation of blade shroud when the shroud is viewed as in FIG. Flange is bent down toward the blade shroud, as shown in FIG. The end of support arm opposite tabs and is pivotally connected to a spreader or splitter Splitter is a flat, metal plate similar to the riving knife discussed above.

The splitter has a side-to-side thickness thinner than the kerf of the blades for which it is intended to be used and the splitter is positioned in the saw behind and within the kerf of the blade, like the riving knife. The splitter, however, extends above the height of the fully elevated blade so that a blade shroud may be mounted thereto. Splitter includes a front edge curved to follow the perimeter of the blades with which the splitter is to be used, like the leading edge of the riving knife discussed above.

The splitter also includes a rounded tip similar to the tip of a riving knife. Curved edge and tip are chamfered so that they do not catch on a workpiece. Splitter also includes an upper edge extending up and away from tip and a portion of that upper edge is chamfered.

Splitter includes a base with shoulders, edges, holes and cutouts like those in the riving knife discussed above so that the splitter may fit into mounting system , as shown in FIGS. Support arm includes two side walls and labeled in FIG. A corresponding hole is positioned in splitter toward the top and back of the splitter. Support arm is positioned over the splitter so that hole and align with hole A nut shown in the assembly in FIG.

Nut includes a recessed section with a shoulder Recessed section is sized to fit into hole without any significant play. Recessed area is also sized so that it preferably does not extend through hole beyond the outer surface of wall so as to minimize the overall width of the blade guard assembly.

Shoulder is sized larger than hole so that the shoulder abuts the inside surface of wall Nut also includes a threaded hole to receive a screw, as will be explained. A spacer shown in FIGS. Spacer includes a recessed section with a shoulder , and recessed area is sized to fit into hole without any significant play. Recessed area is sufficiently long so that it extends through hole and slightly beyond the outer surface of wall Spacer also includes a hole through which a screw may pass.

A screw shown in FIG. As screw threads into nut , the nut is drawn against the splitter and the washer and lock washer are drawn against the end of spacer that extends through hole Thus, threading the screw into nut causes the nut and spacer to clamp the splitter around hole and thereby pivotally mount the support arm on the splitter.

The pivot connection between splitter and support arm is a metal-to-metal pivot, as with the pivot connection between blade shroud and support arm , because holes and in the support arm contact the recessed areas or shoulders on nut and metal spacer Support arm includes a cutout to provide clearance for the splitter when the support arm pivots up. The size of the cut out will determine how far upward the support arm can pivot.

A charge and discharge control device is installed in the electric motor vehicle to provide a communication with the external loading and unloading and to perform a charge and discharge processing with the storage device. Die Lade- und Entlade-Steuervorrichtung bestimmt, unter Berücksichtigung verschiedener Bedingungen, einen Stromstärkenwert, mit dem ein Laden und Entladen durchgeführt wird, eine Zeit, zu der ein Laden und Entladen gestartet wird, und eine Zeit, zu der ein Laden und Entladen endet, um die Speichervorrichtung des Elektromotorfahrzeugs zu laden oder zu entladen.

The charge and discharge control device determines, taking into account various conditions, a current value with which loading and unloading is carried out, a time at which charging and discharging is started and a time at which a charging and discharging ends to charge the storage device of the electric motor vehicle or unload.

Verschiedene Bedingungen enthalten den Zustand der Speichervorrichtung, wie zum Beispiel eine Speicherkapazität und eine Temperatur der Speichervorrichtung, eine Nennkapazität der Speichervorrichtung, eine Nennkapazität der externen Lade- und Entladeanlage, eine elektrische Rate und ein verfügbarer elektrischer Strom, die mit der Zeit variieren und eine abgeschätzte Zeit, zu der der Benutzer das Elektromotorfahrzeug als Nächstes verwendet, zum Beispiel. Various conditions include the condition of the memory device, such as a storage capacity and a temperature of the storage device, a rated capacity of the storage device, a rated capacity of the external loading and unloading station, an electrical rate and an available electric power, which vary with time and an estimated time at which the user uses the electric motor vehicle next, for example.

Um elektrische Kosten während eines Fahrens des Elektrofahrzeugs zu verbessern, und zum Beispiel eine entladene Batterie zu verhindern, die durch ein Verbrauchen von in der Batterie gespeichertem Stroms verursacht wird, wenn das Elektromotorfahrzeug nicht verwendet wird, ist die Lade- und Entlade-Steuervorrichtung bevorzugter Weise in einem Bereitschaftszustand, in dem der Stromverbrauch niedrig ist, wenn der Lade- und Entladebetrieb nicht durchgeführt wird.

In order to improve electrical charges during running of the electric vehicle, and, for example, to prevent a discharged battery, which is caused by a consuming in the battery stored current when the electric motor vehicle is not used, the charge and discharge control device is preferably in a standby state in which the power consumption is low when the charging and discharging operation is not performed.

Wenn andererseits der Benutzer den Lade- und Entladebetrieb startet, wird von der Lade- und Entlade-Steuervorrichtung erwartet, in einem aktivierten Zustand zu sein, in dem die Lade- und Entladeverarbeitung möglich ist, oder in den aktivieren Zustand innerhalb kurzer Zeit überzugehen. Otherwise, if the user starts the charging and discharging, is expected of the charge and discharge control device to be in an activated state in which the charge and discharge processing is possible or transition to the enable state within a short time.

Eine eine elektrische Steuerung durchführende Steuervorrichtung muss verschiedene Prozeduren ausführen, um in dem aktivierten Zustand zu sein, nachdem eine Stromversorgung angeschaltet wird. An electrical control by leading control device needs to perform various procedures to be in the activated state, after a power supply is turned on. Zum Beispiel müssen eine Boot-Verarbeitung zum Lesen eines Betriebssystems OS in eine zentrale Verarbeitungseinheit CPU , eine Verarbeitung zum Initialisieren verschiedener Typen von Hardware und Speicher, durchgeführt von dem OS, eine Fehlerdiagnoseverarbeitung, eine Verarbeitung zum Lesen und Aktivieren eines Steueranwendungsprogramms aus einem nichtflüchtigen Aufzeichnungsmedium und dergleichen durchgeführt werden.

For example, a boot processing need for reading an operating system OS in a central processing unit CPU , processing for initializing various types of hardware and memory, performed by the OS, a fault diagnosis processing, a processing for reading and activation of a control application program from a non-volatile recording medium and the like may be performed.

Einige Vorrichtungen benötigen somit eine lange Zeit, um aktiviert zu werden. Some devices thus require a long time to be activated. Eine Fahrzeugnavigationsvorrichtung ist ein typisches Beispiel einer Fahrzeugvorrichtung, die eine lange Zeit benötigt, um aktiviert zu werden. A vehicle navigation device is a typical example of a vehicle device that takes a long time to be activated. Eine Technologie zum Verbessern der Benutzerfreundlichkeit, während ein Stromverbrauch während eines Bereitschaftszustands unterdrückt wird, wird studiert siehe zum Beispiel Patentdokumente 1 und 2.

A technology for improving the user-friendliness, while a current consumption during a standby state is suppressed, is studied for example, see Patent Documents 1 and 2. Wenn ein Signal von der mobilen Vorrichtung zurückgegeben wird, wird die Navigationsvorrichtung aktiviert, bevor ein Benutzer in das Fahrzeug einsteigt.

When a signal from the mobile device is returned, the navigation device is activated before a user gets in the vehicle. Eine Fahrzeugvorrichtung, die in Patentdokument 2 offenbart wird, zum Beispiel eine Navigationsvorrichtung, wird in einem Betriebszustand für eine bestimmte Periode gehalten, nachdem ein Benutzer die Verwendung der Fahrzeugvorrichtung beendet hat und einen Zubehörschalter abschaltet. A vehicle device that is disclosed in Patent Document 2, for example, a navigation device is held in an operating state for a certain period after a user has finished the use of the in-vehicle device and an accessory switch turns off.

Als Resultat kann der Benutzer die Fahrzeugvorrichtung in einer kurzen Zeit aktivieren, ohne einen Aktivierungsprozess durchzuführen durch Anschalten des Zubehörschalters in der Zeitperiode, während der die Fahrzeugnavigationsvorrichtung in dem Betriebszustand gehalten wird, nachdem der Zubehörschalter abgeschaltet ist.

As a result, the user may activate the vehicle device in a short time without an activation process carried out by turning on the accessory switch in the period during which the car navigation device is held in the operation state after the accessory switch is turned off.

Zusammenfassung der Erfindung Summary of the Invention. Von der Erfindung zu lösende Probleme From the invention Problems to be solved. Unter Fahrzeugvorrichtungen wird von einer Lade- und Entlade-Steuervorrichtung verlangt, eine Vielzahl von Lade- und Entlade-Standards, eine Internet-Kommunikation unter Verwendung verschiedener Protokolle, verschiedene Arten von Verschlüsselung, Authentifizierung und Regelungsverarbeitung zu unterstützen, um ein effizientes Laden und Entladen im Hinblick auf eine elektrische Rate zu erreichen, die mit der Zeit variiert.

Under vehicle devices, a large number of charge and discharge standards, an Internet communications using different protocols, different types of encryption, authentication and control processing required by a charge and discharge control device, to support an efficient charging and discharging in to achieve with regard to an electrical rate that varies with time.

This complicates communication between the charge and discharge control apparatus in the vehicle and a communication device outside the vehicle. In addition, a complicated data processing is required in order to plan a charging and discharging and to control charging and discharging, whereby the number of installed in the charge and discharge control device parts is increased, and a capacity of a nonvolatile memory with an enlarged program scale.

Eine Zeit, die benötigt wird für eine Fehlerdiagnose zu der Zeit einer Aktivierung, für einen zyklischen Redundanzcheck CRC eines nicht-flüchtigen Speichers, für eine Initialisierung verschiedener Typen von Hardware und nicht-flüchtigem Speicher und für eine Aktivierung eines Steuerprogramms tendieren dazu, dramatisch anzusteigen.

A time which is required for fault diagnosis at the time of activation, for a cyclic redundancy check CRC of a non-volatile memory for initialization of various types of hardware and non-volatile memory and for activating a control program tend to dramatically to increase. Falls es eine lange Zeit dauert, die Lade- und Entlade-Steuervorrichtung von dem Bereitschaftszustand in den aktivierten Zustand zu aktivieren, tritt einer Verzögerung auf zwischen dem Start des von dem Benutzer durchgeführten Lade- und Entladebetriebs und dem tatsächlichen Start der Lade- und Entladeverarbeitung.

If it takes a long time to activate the charge and discharge control device from the standby state to the activated state, a time lag between the start of the operations performed by the user charging and discharging operation and the actual start of the charging and discharge processing.

Dies reduziert die Benutzerfreundlichkeit stark. This reduces the usability strong. Wenn zum Beispiel die Lade- und Entlade-Steuervorrichtung veranlasst wird, von dem Bereitschaftszustand in den aktivierten Zustand überzugehen, beim Erfassen einer Benutzereinfügung einer Ladepistole in einen Zuführungsanschluss des Fahrzeugs, kann der Benutzer das Fahrzeug nicht verlassen, bis der Start des Ladens und Entladens bestätigt wird. For example, when the charge and discharge control device is caused to move from the standby state to the activated state, upon detecting a user insertion of a pistol into a supply port of the vehicle, the user can not leave the vehicle, until the start of charging and discharging confirmed becomes.

Wenn der Benutzer das Fahrzeug verlässt, ohne den Start des Ladens und Entladens zu bestätigen, kann der Benutzer bemerken, dass eine Ladesteuerung nicht erfolgreich gestartet hat, nach Verlassen des Fahrzeugs und kann folglich nicht erwarten, dass ein Laden und Entladen durchgeführt wird.

When the user leaves the vehicle without confirming the start of charging and discharging, the user can notice that a charge controller has not successfully launched, after leaving the vehicle and consequently can not expect a charging and discharging is performed. Wenn der Start einer Kommunikation zwischen der Lade- und Entlade-Steuervorrichtung und der externen Lade- und Entladeanlage verzögert wird, kann eine Verzögerung auftreten, bevor dem Benutzer erlaubt wird, einen Betrieb durchzuführen zum Bereitstellen eines Befehls zum Starten eines Ladens und Entladens an die externe Lade- und Entladeanlage.

When the start of communication between the loading and discharge control apparatus and the external loading and unloading is delayed, a delay may occur before the user is allowed to perform an operation for providing an instruction to start charging and discharging to the external loading and unloading.

Alternativ kann die externe Ladeanlage, die eine Lade- und Entladesteuerung früh gestartet hat, aufgrund eines Zeitablauffehlers fehlschlagen, eine Kommunikation aufzubauen. Alternatively, the external charging system, which has launched a charge and discharge control early, fail due to a timing error to establish a communication. Eine in den oben genannten Patentdokumenten 1 und 2 offenbarte Technologie betrifft eine Navigationsvorrichtung. One disclosed in the above Patent Documents 1 and 2 technology relates to a navigation device.

Die in den Patentdokumenten 1 oder 2 offenbarte Technologie ist nicht auf die Lade- und Entladesteuervorrichtung wie sie ist anwendbar. The invention disclosed in the patent documents 1 or 2 technology is not limited to the charge and discharge control as applicable. For example, if the technique disclosed in Patent Document 1, technology is applied, the charge and discharge control device is activated when there is a response from the mobile device outside of the vehicle, the response from the mobile device, however, does not necessarily mean that the charge and discharge operation is performed.

Die Lade- und Entlade-Steuervorrichtung kann aktiviert werden, wenn der Lade- und Entladebetrieb nicht durchgeführt wird, und ein Stromverbrauch der Lade- und Entlade-Steuervorrichtung kann nicht ausreichend reduziert werden. The charge and discharge control device can be activated when the charging and discharging operation is not performed, and a power consumption of the charge and discharge control device can not be sufficiently reduced.

Die in Patentdokument 2 offenbarte Technologie ist nur anwendbar nach der Verwendung der Fahrzeugvorrichtung. The invention disclosed in Patent Document 2, technology is only applicable to the use of the vehicle device.

Eine Anwendung der in Patentdokument 2 offenbarten Technologie kann eine Zeitperiode nicht reduzieren, bis die Lade- und Entlade-Steuervorrichtung die Lade- und Entladeverarbeitung startet, wenn der Lade- und Entladebetrieb vor der Verwendung des Elektromotorfahrzeugs durchgeführt wird. An application of the method disclosed in Patent Document 2, technology can not reduce until the charge and discharge control device, the charge and discharge processing starts when the charging and discharging operation is performed before the use of the electric motor vehicle, a period of time.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Lade- und Entlade-Steuervorrichtung bereitzustellen, die die Zeitperiode reduzieren kann, bis die Lade- und Entlade-Steuervorrichtung gestartet wird, während ein Stromverbrauch während einer Nichtverwendung reduziert wird, und ein die Lade- und Entlade-Steuervorrichtung enthaltendes Elektromotorfahrzeug bereitzustellen.

It is an object of the present invention to provide a charge and discharge control device which can reduce the time period until the charge and discharge control apparatus is started, while a current consumption during non-use is reduced, and the charge and discharge provide registration control apparatus containing an electric motor vehicle.

Ein Elektromotorfahrzeug der vorliegenden Erfindung ist ein Elektromotorfahrzeug, das enthält: Effekte der Erfindung Effects of the Invention. According to the charge and discharge control device of the present invention, the charge and discharge process-prediction unit predicts whether the charging and discharging operation is started installed in the motor vehicle storage device or not.

In Übereinstimmung mit dem Ergebnis der Vorausberechnung verwaltet die Verwaltungseinheit den Betriebszustand der Lade- und Entladesteuerung. In accordance with the result of the prediction, the management unit manages the operation state of the charge and discharge control.

Als Resultat kann die Lade- und Entladesteuerung in dem aktivierten Zustand sein, in dem die Lade- und Entladeverarbeitung der Speichervorrichtung möglich ist, bevor ein Benutzer den Lade- und Entladebetrieb startet. As a result, the charge and discharge control in the activated state may be, in which the charge and discharge processing of the memory device is possible before a user starts the charging and discharging. Die Lade- und Entladesteuerung kann die Lade- und Entladeverarbeitung unmittelbar starten, nachdem der Benutzer den Lade- und Entladebetrieb startet.

The charge and discharge can start the charge and discharge processing immediately after the user starts the charging and discharging. Characterized in that the charge and discharge process-precomputation unit regularly calculated in advance whether the charging and discharging operation is started or not, the state of charge and discharge control can be switched in accordance with the status of performing charging and discharging operations. Die Lade- und Entladesteuerung kann zum Beispiel in dem Bereitschaftszustand gehalten werden, in dem ein Stromverbrauch kleiner ist als in dem aktivierten Zustand, während einer Zeitperiode, indem der Lade- und Entladebetrieb vorausberechnet wird, gestartet zu werden.

The charge and discharge control can be maintained, for example, in the standby state in which a power consumption is smaller than in the activated state, during a period of time by the charging and discharging operation is predicted to be started.

Die Lade- und Entladesteuerung kann veranlasst werden, von dem aktivierten Zustand in den Bereitschaftszustand über zu gehen in einem Fall, dass der Lade- und Entladebetrieb nicht durchgeführt wird, wenn eine bestimmte Zeitperiode abgelaufen ist, seit einer Vorausberechnung des Starts des Lade- und Entladebetriebs. The charge and discharge can be caused to move from the activated state to the standby state in a case that the charging and discharging operation is not performed when a particular period of time has elapsed since an advance calculation of the start of charging and discharging operations , Die Lade- und Entladesteuerung kann dadurch effizient in dem Bereitschaftszustand sein, was zu einer Verbesserung von elektrischen Kosten des Elektromotorfahrzeugs führt.

The charge and discharge can thereby be efficient in the standby state, resulting in an improvement of electrical cost of the electric motor vehicle. Ein Verbrauch des in der Speichervorrichtung gespeicherten Stroms kann verringert werden, wenn das Elektromotorfahrzeug nicht verwendet wird.

A consumption of the data stored in the storage device current can be reduced when the electric motor vehicle is not used. Wie oben beschrieben, kann eine Zeitperiode bis die Lade- und Entladeverarbeitung gestartet wird, reduziert werden, während ein Stromverbrauch während einer Nichtverwendung reduziert wird. As described above, a period of time can be reduced is to charge and discharge processing is started, while a current consumption during non-use is reduced.

According to the electric motor vehicle of the present invention, the above-mentioned charge and discharge control device of the present invention controls charging and discharging of the storage device. Als solches kann die Zeitperiode, bis die Lade- und Entladeverarbeitung der Speichervorrichtung gestartet wird, reduziert werden, während ein Stromverbrauch reduziert wird, wenn das Elektromotorfahrzeug nicht verwendet wird. As such, the time period until the charge and discharge processing is started, the memory device can be reduced while a power consumption is reduced when the motor vehicle is not used.
