Description

  The present invention relates to an opening / closing member control device, and more particularly, to an opening / closing member control device that performs an opening / closing operation while controlling the position of the opening / closing member.

  The opening / closing member control device has been known in the past, and an example thereof is a vehicle window glass lifting control device. This window glass raising / lowering control apparatus is configured to transmit the rotational force of the electric motor to the raising / lowering mechanism and to raise / lower the window glass via the raising / lowering mechanism. Among such lift control devices, there is one that stops the window glass in front of the fully open position (position where mechanical locking is stopped during the opening operation) when the window glass is lowered by motor drive (for example, , See Patent Document 1).

  Normally, if the window glass is moved to the fully open position, the window glass is mechanically restrained by the stopper, and an excessive impact force is applied to the drive system at this time, impairing the durability of the drive system and uncomfortable impact. Sound is generated. On the other hand, in the apparatus described in Patent Document 1, in order to avoid the inconvenience as described above, the current position of the window glass is accurately grasped, and the window glass is not lowered to the fully open position immediately before it. Stops at the position.

  By the way, the window glass stop position (hereinafter, set stop position) set as the position immediately before the fully open position is set on the basis of, for example, the fully closed position (the position where mechanical locking is stopped during the closing operation). . However, the fully closed position may vary due to aging of the vehicle (particularly the mechanism around the window glass), and the actual position may be different from the position stored in the apparatus. Along with this, there is a possibility that a relative deviation occurs between the position set as the window glass stop position and the position where the window glass actually stops during the lowering operation.

  For this reason, in recent years, there has been proposed a control device capable of resetting the stop position of the window glass as appropriate (see, for example, Patent Document 2). In the device described in Patent Document 2, the window glass is forcibly moved to the fully closed position beyond the set stop position, triggered by the vehicle occupant performing a predetermined switch operation. The set stop position is reset based on the forced stop position stopped at the first time.

Utility Model Registration No. 2577092 JP 2007-146696 A

  However, according to the technique described in Patent Document 2, the vehicle occupant must perform a predetermined switch operation to execute the reset process of the set stop position, which is troublesome. In the technique described in Patent Document 2, the setting stop position is not reset unless a predetermined switch operation is performed. For example, even if the fully closed position is changed, the setting stop position is corrected. There is a risk of being left untreated. Since the relative position relationship between the fully closed position and the set stop position does not change as long as the set stop position is not reviewed, the set stop position initially set to a suitable position is accompanied by a change in the fully closed position. May change to an inappropriate position.

  More specifically, when the set stop position is set to a position where the window glass is completely accommodated in the door, if the fully closed position fluctuates, the actual stop position, that is, the window is accordingly changed. The position at which the glass is forced to stop when the glass reaches the set stop position is different from the above position. As a result, when the window glass is forcibly stopped, the window glass may not be completely accommodated in the door and may remain inside the door window frame.

  In view of the above problems, an object of the present invention is to provide an opening / closing member control apparatus capable of appropriately resetting the set stop position without requiring a separate user operation.

According to the opening / closing member control apparatus of the present invention, the problem is that a driving mechanism that drives an opening / closing member that can move between a fully open position and a fully closed position, and a position of the opening / closing member that is based on the fully closed position. A position detection mechanism that detects the position, a fully closed position, and a set stop position that is set to be closer to the fully closed position than the fully open position with reference to the fully closed position. When the mechanism and the drive mechanism are driving the opening / closing member toward the fully open position, the position of the opening / closing member detected by the position detection mechanism matches the set stop position stored in the storage mechanism. And a control mechanism that controls the drive mechanism so that the opening / closing member stops at the set stop position, and when the drive mechanism drives the opening / closing member toward the fully closed position, The open / close member is in the fully closed position. Position of the closing member, wherein the position detecting mechanism detects upon Tsu is, if different from the been the fully closed position stored in the storage mechanism, the control mechanism, does not change the absolute position of the setting stop position As described above, the setting stop position stored in the storage mechanism is automatically corrected according to the position of the opening / closing member detected by the position detection mechanism when the opening / closing member reaches the fully closed position. It is solved by.

  With the opening / closing member control device of the present invention configured as described above, the position of the opening / closing member detected by the position detection mechanism when the opening / closing member reaches the fully closed position, and the fully closed position stored in the storage mechanism Is different from the above, it is possible to execute the correction process of the set stop position without requiring a separate user operation. The set stop position after correction is a position corresponding to the fully closed position after the change. As a result, in the opening / closing member control device of the present invention, it is possible to accurately respond to fluctuations in the fully closed position and forcibly stop the opening / closing member at a position set appropriately according to the fully closed position after the change. It becomes.

In the opening / closing member control device, the control mechanism detects the position detecting mechanism when the opening / closing member reaches the fully closed position when correcting the setting stop position stored in the storage mechanism. It is preferable to correct the set stop position so that the set stop position is shifted by an amount corresponding to the difference between the position of the opening / closing member and the fully closed position stored in the storage mechanism.
If the set stop position is corrected so that it shifts by the amount corresponding to the amount of change when the fully closed position changes as in the above configuration, the position is set appropriately according to the fully closed position after the change. The effect of the present invention for forcibly stopping the opening / closing member will be more effectively exhibited.

In the above-described opening / closing member control device, the position detection mechanism detects when the opening / closing member reaches the fully closed position when the drive mechanism drives the opening / closing member toward the fully closed position. When the position of the opening / closing member moved further away from the fully open position than the fully closed position stored in the storage mechanism, the control mechanism moves the setting stop position to the fully open position side by an amount corresponding to the difference. It is more preferable to correct the set stop position stored in the storage mechanism so as to shift.
As described above, when the position of the opening / closing member detected by the position detection mechanism when the opening / closing member reaches the fully closed position is set to be farther from the fully opened position than the fully closed position stored in the storage mechanism. If the stop position is corrected so as to be shifted to the fully open position side, the position where the open / close member is actually forcibly stopped is the same before and after the change of the fully closed position. Therefore, the effect of the present invention for forcibly stopping the opening / closing member at a position appropriately set according to the fully closed position after the change is more effectively exhibited.

In the above-described opening / closing member control device, the opening / closing member is a vertically movable window glass attached to a vehicle door, and the setting stop position is such that the drive mechanism brings the window glass to the fully closed position. It is set to a position that is lower than the fully closed position by the driving amount when the window glass is driven from the positioned state until the upper end of the window glass is lower than the door belt molding provided on the door. It is good to be.
If it is the above structure, the effect of this invention will become more effective. That is, when the set stop position is set so that the upper end of the window glass is positioned below the door belt molding when the window glass reaches the set stop position, even if the fully closed position changes, the window glass The forced stop position is maintained at the above position. Therefore, before and after the change of the fully closed position, the window glass can be appropriately forcibly stopped at a position completely accommodated in the door without reaching the fully opened position.

  According to the opening / closing member control device of the present invention, when the position of the opening / closing member detected by the position detection mechanism when the opening / closing member reaches the fully closed position is different from the fully closed position stored in the storage mechanism, It is possible to execute the setting stop position correction process without requiring a separate user operation. The set stop position after correction is a position corresponding to the fully closed position after the change. As a result, in the opening / closing member control device of the present invention, it is possible to accurately respond to fluctuations in the fully closed position and forcibly stop the opening / closing member at a position set appropriately according to the fully closed position after the change. It becomes.

  Hereinafter, as an example of the opening / closing member control device of the present invention, a power window device to which the present invention is applied will be described as an example. That is, hereinafter, as an example of the opening and closing member, the window glass 11 attached so as to be movable up and down with respect to the door of the vehicle will be described, and an apparatus for controlling the operation of the window glass 11 will be described.

  As shown in FIGS. 1 and 2, the power window device 1 according to the present embodiment is controlled by a drive mechanism 2 that opens and closes a window glass 11, a control mechanism 3 that controls the drive mechanism 2, and a vehicle occupant. The operation switches 4 and 5 operated by the occupant when giving a command to the mechanism 3 are the main components.

In the present embodiment, the window glass 11 has an upper end edge along an unillustrated rail whose upper edge is between an upper fully closed position (fully closed lock stop position) P0 and a lower fully open position (fully open lock stop position) P2. It is configured to be movable between. The fully closed position P0 and the fully open position P2 are the upper and lower movement limit of the window glass 11. At this position, the window glass 11 is restricted from moving up and down further due to its structure.
However, the fully closed position P0 and the fully open position P2 may slightly fluctuate due to changes over time. For example, the movement limit may slightly vary due to a change in the degree of contact with a weather strip provided on the window frame.

  In the present embodiment, the window glass 11 is controlled to stop at the set stop position P1 that is set to the front side of the fully open position P2, that is, the fully closed position P0 side, when fully open. Thereby, when the window glass 11 is lowered, the driving system member is brought into contact with the driving system member at the lower end position, and an impact force is applied to the driving system member, thereby preventing an impact sound from being generated. Yes. Therefore, the window glass 11 according to the present embodiment is configured to move up and down between the fully closed position P0 and the set stop position P1 during normal times.

  In the power window device 1 according to the present embodiment, the control mechanism 3 moves the window glass 11 to indicate that a foreign object has been sandwiched between the upper edge of the window glass 11 and a window frame (not shown) during the closing operation. It has a pinch detection function that detects from the amount of change in speed. And the control mechanism 3 is comprised so that the drive mechanism 2 may be reversed and the window glass 11 will be lowered | hung, and a foreign material will be open | released, when pinching is detected.

On the other hand, in the vicinity of the fully closed position P0, the sliding resistance applied to the window glass 11 by a weather strip (not shown) increases, and thereby the moving speed of the window glass 11 decreases. For this reason, in the present embodiment, in order to prevent the above-described speed reduction from being erroneously detected as pinching, a range from a position somewhat before the fully closed position P0 (fully opened position P2 side) to the fully closed position P0 is set. These are set as a pinching detection release region (so-called dead zone region) where pinching detection is not performed.
In addition, since a well-known mechanism (for example, the pinching detection mechanism described in Patent Document 2 described above) can be used as the pinching detection mechanism, a detailed description of the configuration is omitted.

As shown in FIG. 1, the drive mechanism 2 of this example includes a motor 20 attached to a door, a main pulley 12 coupled to an output shaft of the motor 20, two driven pulleys 13 and 14, a pulley 12, And an endless wire 15 laid across 13 and 14. Further, a portion of the wire 15 located between the driven pulleys 13 and 14 is locked to a fixing member 16 formed on the window glass 11.
In the drive mechanism 2 configured as described above, when the pulleys 12, 13, and 14 are rotated by the rotation of the motor 20, the window glass 11 and the wire 15 operate integrally. The window glass 11 is configured to open and close in conjunction with the driving of the wire 15.

  Note that the configuration of the drive mechanism 2 is not limited to the above configuration, and other mechanisms (for example, an X-link type mechanism) are applicable as long as the window glass 11 can be opened and closed. ).

  In the present embodiment, the motor 20 is configured to rotate by receiving power supply from the control mechanism 3, more specifically, the battery 6. Furthermore, in the present embodiment, a rotation detection device 21 is attached to the motor 20. The rotation detection device 21 outputs a pulse signal synchronized with the rotation of the motor 20 to the control mechanism 3. The rotation detection device 21 according to the present embodiment includes a plurality of Hall elements, and outputs a pulse signal for each predetermined movement amount of the window glass 11 or for each predetermined rotation angle of the motor 20. That is, the rotation detection device 21 can output a signal corresponding to the movement of the window glass 11 that is substantially proportional to the rotation speed of the motor 20.

  The control mechanism 3 detects the position of the window glass 11 based on the pulse signal from the rotation detection device 21. More specifically, the control mechanism 3 uses the fully closed position P0 as a reference position (origin position), and the pulse count value counted up from the time when the window glass 11 reaches the position (the pulse count value will be described later). The position of the window glass 11 is specified based on the above. Thus, in the present embodiment, the rotation detection device 21 and the control mechanism 3 constitute a position detection unit.

  In the present embodiment, the rotation detection device 21 is configured by a Hall element. However, the rotation detection device is not limited to this, and if the rotation of the motor 20 can be detected, the rotation detection device is configured by a component other than the Hall element, for example, an encoder. 21 may be configured. In the present embodiment, the position of the window glass 11 is detected based on the number of rotations of the motor 20, more specifically, the pulse signal output from the rotation detection device 21. The position of the window glass 11 may be directly detected by the means.

As shown in FIG. 2, the control mechanism 3 of the present embodiment includes a controller 31 and a drive circuit 32. The controller 31 and the drive circuit 32 are supplied with electric power necessary for operation from a battery 6 mounted on the vehicle.
In the present embodiment, the controller 31 is configured by a microcomputer incorporating a CPU. However, the present invention is not limited to this, and the controller 31 may be configured by a logic IC, a DSP, a gate array, a transistor, or the like.

When the controller 31 normally receives the operation signal transmitted from the operation switches 4 and 5, the controller 31 rotates the motor 20 forward and backward via the drive circuit 32 based on the operation signal. As a result, the window glass 11 moves to open and close.
Further, the controller 31 detects the position of the window glass 11 based on the pulse signal received from the rotation detection device 21, and the amount of power supplied to the motor 20 via the drive circuit 32 according to the detected position of the window glass 11. Adjust the height. More specifically, the controller 31 according to the present embodiment adjusts the magnitude of the duty ratio in PWM control of the magnitude of the supply voltage, thereby adjusting the motor output.

The drive circuit 32 is for switching the polarity of power supply to the motor 20 based on an input signal from the controller 31. Specifically, when receiving a forward rotation command signal from the controller 31, the drive circuit 32 supplies electric power to the motor 20 so as to rotate the motor 20 in the forward rotation direction. On the other hand, when receiving a reverse rotation command signal from the controller 31, the drive circuit 32 supplies power to the motor 20 so as to rotate the motor 20 in the reverse rotation direction.
In the present embodiment, as shown in FIG. 2, the drive circuit 32 is separated from the controller 31. However, the present invention is not limited to this, and the drive circuit 32 is incorporated in the controller 31. It may be.

  The controller 31 detects a rising portion and a falling portion (pulse edge) of the pulse signal input from the rotation detection device 21, and determines the rotation speed (rotation cycle) of the motor 20 based on the interval (cycle) of the pulse edge. While calculating, the rotation direction of the motor 20 is detected based on the phase difference of each pulse signal. That is, the controller 31 indirectly calculates the movement speed of the window glass 11 based on the rotation speed (rotation period) of the motor 20 and specifies the movement direction of the window glass 11 based on the rotation direction of the motor 20. .

  The controller 31 counts pulse edges. On the other hand, the pulse count value N is a value that is added or subtracted with the opening / closing operation of the window glass 11. Then, the controller 31 specifies the opening / closing position of the window glass 11 based on the magnitude of the pulse count value N.

  More specifically, in the present embodiment, the fully closed position P0 is set as a reference position (origin position), and the pulse count value N is set to 0 at the fully closed position P0. When the drive mechanism 2 is driving the window glass 11 toward the fully open position P2, the pulse count value N is incremented by 1 each time the controller 31 receives a pulse signal. On the contrary, when the drive mechanism 2 is driving the window glass 11 toward the fully closed position P0, the pulse count value N is decremented by 1 every time the controller 31 receives the pulse signal.

  More specifically, a vehicle equipped with the power window device 1 according to the present embodiment is provided with two operation switches for operating the power window device 1. The two switches are an ascending switch 4 and a descending switch 5, each of which is constituted by a swinging switch that can be operated in two steps.

  Then, when the occupant operates the lift switch 4, a command signal for closing the window glass 11 is output to the controller 31. When the controller 31 receives the command signal, the controller 31 turns on the closing operation flag according to the command signal. Then, the drive circuit 32 is controlled based on the closed operation flag that is turned on. Here, when the raising switch 4 is operated in one step, the switch operation corresponds to a manual operation, and the closing operation (the raising operation of the window glass 11) is performed only during the operation. On the other hand, when the raising switch 4 is operated in two steps, the operation corresponds to an automatic operation. Even if the operation is stopped, the closing operation is continued until the upper edge of the window glass 11 reaches the fully closed position P0. .

  Similarly, when the occupant operates the lowering switch 5, a command signal for opening the window glass 11 is output to the controller 31. When the controller 31 receives the command signal, the controller 31 turns on the opening operation flag according to the command signal. Then, the drive circuit 32 is controlled based on the open operation flag that is turned on. Here, when the lowering switch 5 is operated in one step, the switch operation corresponds to a manual operation, and the opening operation (the lowering operation of the window glass 11) is performed only during the operation. On the other hand, when the lowering switch 5 is operated in two steps, the operation corresponds to an automatic operation, and the opening operation is continued until the upper edge of the window glass 11 reaches the set stop position P1 even if the operation is stopped. .

  As described above, in this embodiment, when the controller 31 receives the auto close command signal, the close operation flag is latched on. Similarly, when the controller 31 receives an auto-open command signal, the open operation flag is latched on. The drive circuit 32 is controlled based on these flags. These flags are changed to OFF under a predetermined condition, and the driving of the window glass 11 is stopped.

  In the present embodiment, the controller 31 includes a memory 33 as a storage mechanism, as shown in FIG. The memory 33 is configured by a ROM, a RAM, and the like, and stores a fully closed position P0, a set stop position P1, and a fully opened position P2 in this embodiment.

More specifically, the memory 33 stores the correspondence shown in FIG. This correspondence is a correspondence between the position of the window glass 11 and the pulse count value N, and the pulse count value N corresponding to the fully closed position P0 is set to zero. That is, the fully closed position P 0 stored in the memory 33 corresponds to the origin position of the window glass 11.
In the present embodiment, when the window glass 11 is in a locked state without causing pinching in the closing operation, the controller 31 determines that the window glass 11 has reached the fully closed position P0, and the pulse count value N A reset process is performed to return 0 to 0.

  The correspondence relationship stored in the memory 33 will be further described. The pulse count value N corresponding to the set stop position P1 is set to N1, and the pulse count value N corresponding to the fully open position P2 is set to N2. These pulse count values N are determined relative to the pulse count value (that is, 0) corresponding to the origin position.

  Then, the controller 31 identifies the position of the window glass 11 by comparing the pulse count value N added / subtracted in accordance with the raising / lowering of the window glass 11 and the value stored in the memory 33, and then driving. The operation of the mechanism 2 is controlled. For example, when the drive mechanism 2 is driving the window glass 11 toward the fully closed position P0 (that is, during the closing operation), the actual position of the window glass 11 detected based on the pulse count value N is stored in the memory 33. The controller 31 controls (stops) the drive mechanism 2 so that the window glass 11 stops at the set stop position P1.

  Furthermore, in this embodiment, the controller 31 can reset the pulse count value N corresponding to the set stop position P1 stored in the memory 33, more specifically, the set stop position P1. The resetting of the setting stop position P1 will be described in detail later.

Next, operation | movement of the window glass 11 in this embodiment is demonstrated roughly.
In the present embodiment, when receiving the continuous normal close command signal or the auto close command signal from the ascending switch 4, the controller 31 continuously supplies the drive voltage so as to drive the motor 20 to the fully closed position P0 side. . On the other hand, when receiving a continuous normal opening command signal or an automatic opening command signal from the lowering switch 5, the controller 31 continuously supplies a driving voltage so as to drive the motor 20 to the fully opened position P2. As a result, the motor 20 rotates and the drive mechanism 2 receives the driving force from the motor 20 to open and close the window glass 11.

  On the other hand, as described above, the range in which the window glass 11 is movable is a range from the fully closed position P0 to the fully open position P2, and each of the fully closed position P0 and the fully open position P2 is the window glass 11 beyond that. This is a mechanical lock position where the movement is forcibly stopped. Therefore, when there is no secular change or the like, the window glass 11 is moved to the closing direction and the pulse count value N becomes 0 unless the disturbance such as pinching occurs. To reach the locked state.

  On the contrary, when the window glass 11 moves in the opening direction and the pulse count value N becomes N1, the window glass 11 is forcibly stopped. That is, when the position of the window glass 11 coincides with the position where the pulse count value N = N1, that is, the set stop position P1, the controller 31 interrupts the power supply to the motor 20, and the window glass 11 further opens to the fully open position. The movement toward P2 is restricted.

  Here, in the present embodiment, as described above, the set stop position P1 is set to the near side (fully closed position P0 side) by a predetermined distance from the fully opened position P2. Specifically, the set stop position P1 is set to a position that is offset to the front by the number of pulse counts corresponding to a predetermined distance from the fully open position P2. In the present embodiment, as shown in FIG. 1, the upper end position of the window glass 11 is lower than the door belt molding 17 (more specifically, the belt molding on the down side) than the door belt molding 17 position. The position is set to come.

In other words, in the present embodiment, the setting stop position P1 is changed from the state in which the drive mechanism 2 positions the window glass 11 to the fully closed position P0 until the upper end of the window glass 11 is below the door belt molding 17. Only the driving amount at the time of driving is set to a position below the fully closed position P0.
The reason why the setting stop position P1 is set at the above position is to fully accommodate the window glass 11 in the door by the full opening operation. When the window glass 11 is completely accommodated in the door, the periphery of the window frame of the vehicle door has a good appearance, and the occupant's body interferes with the window glass 11 remaining inside the window frame. This is also avoided.

  Incidentally, as described above, the set stop position P1 is set based on the origin position (that is, the fully closed position P0 stored in the memory 33). On the other hand, the actual fully closed position P0 may vary due to secular change. When the fully closed position P0 varies, the set stop position P1 set based on the fully closed position P0 may deviate from the initially set position.

  More specifically, when the fully closed position P0 changes upward from the position stored in the memory 33, the pulse count value N becomes a negative value before the window glass 11 is locked during the closing operation. End up. As described above, in the present embodiment, when the window glass 11 is locked in the closing operation, the controller 31 resets the pulse count value N. That is, the fully closed position P0 is changed to a position where the pulse count value N is a negative value, and the changed fully closed position P0 becomes the reference position (origin position) in the subsequent opening / closing operations.

  As described above, when the fully closed position P0 changes, the relative positional relationship of the set stop position P1 with respect to the fully closed position P0 also changes. However, if the set stop position P1 remains the position set with reference to the fully closed position P0 before the change, the original set stop position P1 (initially set as the set stop position P1) in the next fully opened operation. The window glass 11 cannot be stopped at the position where it was made. Due to such problems, in some cases, when the window glass 11 is fully opened, the upper end of the window glass 11 may be positioned above the door belt molding 17.

  Therefore, in the present embodiment, when the fully closed position P0 changes, correction of the set stop position P1 is also executed. Further, in the present embodiment, when the window glass 11 is locked during the closing operation, if the detected position of the window glass 11 is different from the fully closed position P0 stored in the memory 33, the controller 31 automatically Thus, the correction process for the set stop position P1 is executed. That is, in the present embodiment, when the window glass 11 is locked at a position different from the fully closed position P0 stored in the memory 33, a correction process for resetting the setting stop position P1 is automatically executed. .

Hereinafter, the procedure of the correction process of the set stop position P1 will be described.
In the present embodiment, as described above, if the detection position of the window glass 11 is different from the fully closed position P0 recorded in the memory 33 when the window glass 11 is locked during the closing operation, The correction process for the set stop position P1 is executed. Here, the detection position of the window glass 11 is indicated by the pulse count value N, and when the lock state is entered at the fully closed position P0 recorded in the memory 33, the pulse count value N is 0.

  On the other hand, the detection position of the window glass 11 when the window glass 11 reaches the fully closed position P0 is located above the fully closed position P0 stored in the memory 33 (in other words, away from the fully open position P2). Then, the pulse count value N becomes a negative value. In this case, the controller 31 corrects the set stop position P <b> 1 stored in the memory 33 according to the detection position of the window glass 11.

Specifically, in the present embodiment, in the correction process of the set stop position P1, the controller 31 sets the set stop position P1 by the difference between the detected position of the window glass 11 and the fully closed position P0 recorded in the memory 33. The set stop position P1 stored in the memory 33 is corrected so as to shift downward (to the fully open position P2 side).
More specifically, a pulse count value N indicating the detection position of the window glass 11 when the window glass 11 reaches the fully closed position P0, and a pulse count value N corresponding to the fully closed position P0 stored in the memory 33. A difference from (that is, 0) is obtained, and the pulse count value N (that is, N1) corresponding to the set stop position P1 stored in the memory 33 is increased by an amount corresponding to the difference. When these steps are finished, the correction process for the set stop position P1 is completed.

  As described above, in the correction process according to the present embodiment, when the actual fully closed position P0 is shifted upward from the position stored in the memory 33, the set stop position is set by the change amount of the fully closed position P0. The set stop position P1 stored in the memory 33 is corrected so that P1 is offset downward. By executing such correction processing, even if the fully closed position P0 changes, the set stop position P1 with respect to the fully closed position P0 is corrected so that the absolute position of the set stop position P1 does not change. Therefore, when the window glass 11 is fully opened, it is possible to always stop the window glass 11 at a desired stop position.

  In particular, in the present embodiment, when the window glass 11 is locked during the closing operation, if the detected position of the window glass 11 is different from the fully closed position P0 stored in the memory 33, the set stop position P1. Correction is automatically performed. That is, in this embodiment, the correction process of the setting stop position P1 is executed without requiring a separate user operation. Then, the corrected set stop position P1 is a position corresponding to the fully closed position P0 after the change. Thereby, in the power window apparatus 1 which concerns on this embodiment, it respond | corresponds correctly with respect to the fluctuation | variation of the fully closed position P0, and it is a window glass in the position set appropriately according to the fully closed position P0 after a change at the time of opening operation | movement. 11 can be stopped.

Further, in the present embodiment, the set stop position is set so that the upper end of the window glass 11 is positioned below the door belt molding 17 when the window glass 11 reaches the set stop position P1. In such a configuration, the above-described effect, that is, the effect of correcting the set stop position P1 to an appropriate position according to the variation of the fully closed position P0 becomes more effective.
More specifically, even if the fully closed position P0 changes due to the effects described above, the upper end of the window glass 11 is positioned below the door belt molding 17 when the window glass 11 reaches the set stop position P1. To come. Therefore, even after the fully closed position P0 changes, it is possible to stop the window glass 11 at a position where the window glass 11 does not reach the fully open position P2 and is completely accommodated in the door during the opening operation. It becomes.

Next, the processing flow of the controller 31 will be described with reference to FIGS.
The window control process by the controller 31 is repeatedly performed every predetermined time. In this window control process, the controller 31 stores the current operation mode for moving the window glass 11 up and down in the memory 33 while updating it. In the present embodiment, selectable operation modes include an up mode, an auto up mode, a down mode, an auto down mode, and a stop mode. As will be described later, in principle, the operation mode is switched according to the operation of the operation switches 4 and 5.

  In this embodiment, when the raising switch 4 is operated in one step, the operation mode is switched to the up mode and stored in the memory 33 only while the operation is being performed. Similarly, when the lowering switch 5 is operated in one step, the operation mode is switched to the down mode and stored in the memory 33 only while the operation is being performed.

  On the other hand, when the operation switches 4 and 5 are operated in two stages, the operation mode is latched in the auto up mode or the auto down mode and stored in the memory 33. The controller 31 performs various processes according to the operation mode stored in the memory 33. That is, each step described below is executed by the controller 31.

  In the window control process, first, it is determined whether or not the operation mode currently stored in the memory 33 is the up mode (step S1). When the current operation mode is the up mode (Yes in Step S1), the controller 31 performs a closing operation process (Step S11). If the current operation mode is the up mode, step S1 and step S11 are repeated, and if there is no disturbance such as pinching, the window glass 11 moves to the fully closed position P0 and stops. When the window glass 11 is stopped, the operation mode is updated to the stop mode.

  If the current operation mode is not the up mode (No in step S1), it is next determined whether or not the current operation mode is the auto up mode (step S2). When the current operation mode is the auto up mode (Yes in step S2), the controller 31 performs an auto close operation process (step S12). That is, the controller 31 operates the drive mechanism 2 by rotating the motor 20 via the drive circuit 32 in order to move the window glass 11 to the fully closed position P0.

  If the current operation mode is the auto up mode, step S1, step S2, and step S12 are repeated, and if there is no disturbance such as pinching, the window glass 11 moves to the fully closed position P0 and stops. To do. When the window glass 11 is stopped, the operation mode is updated to the stop mode.

  By the way, in this embodiment, as shown in FIG. 6, when proceeding to the closing operation process (step S11) and the automatic closing operation process (step S12) in the flow of FIG. 4, the window glass 11 is within the above-described sandwiching release region. It is determined whether or not it is in a locked state (step S31). Here, if the controller 31 does not continuously receive a pulse signal from the rotation detection device 21 for a predetermined time when the operation mode is the up mode or the auto up mode, the rotation of the motor 20 stops and the window glass 11 is locked. It is determined that it is in a state. In the case of the auto-up mode, the window glass 11 normally moves to the fully closed position P0 unless there is a disturbance such as pinching, and becomes locked when the window glass 11 reaches the fully closed position P0. .

  The case where the window glass 11 is not in the locked state (No in step S31) is a case where the window glass 11 is automatically closed within the normal operating range. In such a case, the following steps S32, S33 and S34 are omitted, and the automatic closing operation is continued.

  When it is determined that the window glass 11 is in the locked state within the pinching release region (Yes in step S31), the controller 31 further determines that the lock position is the origin position, that is, the fully closed position P0 stored in the memory 33. Is determined to be higher (step S32). Specifically, it is determined whether or not the pulse count value N indicating the detection position of the window glass 11 when the window glass 11 is locked is a negative value.

  Here, the case where it is determined that the lock position is above the origin position (Yes in step S32) is a case where the fully closed position P0 is shifted upward due to secular change. In this case, the controller 31 executes the correction process for the set stop position P1 described above (step S33). In the correction process, the controller 31 corrects the set stop position P1 stored in the memory 33 so as to offset the set stop position P1 downward by an amount corresponding to the change in the fully closed position P0.

  After completing the correction process (step S33), the controller 31 resets the pulse count value N (S34), and sets the changed fully closed position P0 as the origin position. Thereafter, the controller 31 switches the operation mode to the stop mode. Thereby, the controller 31 interrupts the power supply to the motor 20, stops the drive mechanism 2, and stops the window glass 11 at the fully closed position P0 (the fully closed position P0 after the change).

  On the other hand, when it is determined that the lock position is not higher than the origin position (No in step S32), the window glass 11 is locked before the fully closed position P0 (fully opened position P2 side) due to a foreign object being caught. Is the case. In this case, the controller 31 continues the automatic closing operation after lowering the window glass 11 by a predetermined distance in order to release the caught foreign matter.

  Returning to FIG. 4, when the current operation mode is not the auto up mode (No in step S2), it is determined whether or not the current operation mode is the down mode (step S3). When the current operation mode is the down mode (Yes in Step S3), the controller 31 performs an opening operation process (Step S24). Then, step S1, step S2, step S3 and step S13 are repeated.

  If the current operation mode is not the down mode (No in step S3), it is determined whether or not the current operation mode is the auto down mode (step S4). If the current operation mode is the auto-down mode (Yes in step S4), the controller 31 performs an auto-open operation process (step S14). That is, the controller 31 operates the drive mechanism 2 by rotating the motor 20 via the drive circuit 32 in order to move the window glass 11 toward the fully open position P2. When the current operation mode is the auto down mode, Step S1, Step S2, Step S3, Step S4 and Step S14 are repeated.

Furthermore, in this embodiment, the controller 31 performs position control with respect to the window glass 11 at the time of opening operation. This control process proceeds according to the procedure shown in FIG. 5, and is repeated in the same manner as the window control process.
First, the controller 31 determines whether or not the current operation mode is a down mode or an auto down mode (step S21). If the current operation mode is neither the down mode nor the auto down mode (No in step S21), the position information of the window glass 11, more specifically, the position flag is ended without being set to “full open”.

  On the other hand, when the operation mode is the down mode or the auto down mode (Yes in Step 21), the controller 31 determines whether or not the current position of the window glass 11 is equal to or higher than the set stop position P1, that is, the window glass 11 It is determined whether or not the position is within the range from the set stop position P1 to the fully open position P2 (step S22). When the current position of the window glass 11 is not less than the set stop position P1 (Yes in step S22), the position flag is set to “fully open” (step S24).

  When the current position of the window glass 11 is closer to the fully closed position P0 than the set stop position P1 (No in step S22), the controller 31 determines that the current position of the window glass 11 is within the normal operating range and locks. It is determined whether or not it has been detected (step S23). Here, the normal operation range is a range located on the side of the fully open position P2 by a predetermined distance or more from the fully closed position P0, more specifically, located below the pinching release region described above, and It is a range located above the set stop position P1.

  When the window glass 11 is locked within the normal operating range (Yes in step S23), the controller 31 sets the position flag to “fully open” (step S24). Thus, in this embodiment, even when the window glass 11 has not reached the set stop position P1, when the window glass 11 is locked for some reason, the position flag is set to “fully open”. On the other hand, if the window glass 11 is not locked within the normal operating range (No in step S23), the controller 31 ends the process without setting the position flag to “fully open”.

  The embodiment described above is merely an example showing a specific configuration of the present invention, and the above-described configuration, procedure, and the like are not intended to limit the present invention, and various modifications are made in accordance with the spirit of the present invention. Of course you can.

  Further, in the above embodiment, when the window glass 11 is locked at a position higher than the fully closed position P0 stored in the memory 33, the setting stop position P1 is corrected. It is not limited to. For example, even when the window glass 11 is locked at a position below the fully closed position P0 stored in the memory 33, the correction process for the set stop position P1 may be executed.

  Moreover, in the said embodiment, although the setting stop position P1 was set to the position where the upper end of the window glass 11 exists below the door belt molding 17, it is not limited to this. As long as the set stop position P1 is above the fully open position P2 (fully closed position P0 side), it may be set to another position. For example, the upper end of the window glass 11 is above the door belt molding 17. It may be set at a certain position.

  Moreover, in the said embodiment, although the example which applied the opening-and-closing member control apparatus of this invention to the power window apparatus 1 of the vehicle was shown, it opens and closes opening-and-closing members, such as not only this but a sunroof opening-and-closing apparatus and a sliding door opening-and-closing apparatus The present invention may be applied to all devices.
