Detailed Description

An embodiment of the vehicle opening/closing body control device will be described below with reference to the drawings.

As shown in fig. 1, the vehicle 1 of the present embodiment includes a slide door 4, and the slide door 4 opens and closes a door opening 3 provided in a side surface 2s of a vehicle body 2. Specifically, the vehicle 1 is provided with a plurality of guide rails 5a to 5c extending in the front-rear direction (left-right direction in fig. 1) of the vehicle 1, and a plurality of guide roller units 6a to 6c connected to the guide rails 5, respectively. The slide door 4 is supported on the side surface 2s of the vehicle body 2 via the guide rails 5 and the guide roller units 6.

These guide rail 5 and guide roller unit 6 can relatively displace the connection position of the guide roller unit 6 with respect to the guide rail 5 along the extending direction of the guide rail 5. Thereby, the sliding door apparatus 10 capable of opening and closing the sliding door 4 provided in the door opening 3 is formed.

The slide door 4 is configured to be moved to the vehicle front side (left side in fig. 1) to be in a fully closed state for closing the door opening 3. The slide door 4 is configured to be opened so that an occupant of the vehicle 1 can ride on and off through the door opening 3 by moving to the vehicle rear side (right side in the drawing).

The vehicle 1 further includes a door opening 13 provided at the rear end portion 2r of the vehicle body 2 and opening rearward. A so-called pop-up back door 14 is provided in the door opening 13.

The rear door 14 opens upward with the upper end portion of the door opening 13 as a pivot point. A pair of support devices 15 having an axial shape and configured to be retractable are provided at both end portions in the width direction of the door opening 13. The pair of support devices 15 are rotatably coupled at their axial ends to the vehicle body 2 and the rear door 14. In the vehicle 1, a rear door device 20 is formed that opens and closes the door opening 13 based on the operation of the support device 15. The rear door apparatus 20 has a so-called rear hatch structure.

The vehicle 1 is provided with a PSD actuator 31 that drives the sliding door 4 to open and close using the motor 30 as a drive source, and a PSDECU35 that controls the operation of the PSD actuator 31. Further, the vehicle 1 is provided with a PBD actuator 41 that drives the back door 14 to open and close using the motor 40 as a drive source, and a PBDECU45 that controls the operation of the PBD actuator 41. Accordingly, the sliding door apparatus 10 and the rear door apparatus 20 have so-called power sliding doors and power rear doors that are driven by motors to perform opening and closing operations, respectively.

Specifically, the pulse signal Sp1 synchronized with the operation of the PSD actuator 31 is input to the PSDECU35. The PSDECU35 detects the movement position Xsd of the sliding door 4 that is opened and closed by the driving force of the PSD actuator 31 by counting the pulse signal Sp1.

Similarly, the pulse signal Sp2 synchronized with the operation of the PBD actuator 41 is also input to the PBDECU45. The PBDECU45 detects the movement position Xbd of the back door 14 which is opened and closed by the driving force of the PBD actuator 41 by counting the pulse signal Sp2.

The movement position Xsd of the slide door 4 is represented by, for example, its fully closed position, a pulse count value based on the fully closed position, or the like. The movement position Xbd of the rear door 14 is also represented by a fully closed position thereof, a pulse count value based on the fully closed position, or the like.

The PSDECU35 is inputted with an operation input signal Scr1 to an operation input unit 53 such as a door handle 51 provided in the slide door 4, a portable device 52 held in the vehicle cabin and a user of the vehicle 1. The PSDECU35 controls the operation of the PSD actuator 31, that is, performs the opening/closing drive control of the slide door 4, based on the opening/closing operation request of the slide door 4 and the detected movement position Xsd indicated by the operation input signal Scr1.

Similarly, the PSDECU35 is also inputted with an operation input signal Scr2 to an operation input unit 55 provided in the rear door 14, the vehicle body 2, the portable device 52, and the like. Specifically, the vehicle 1 includes an operation switch 56 as an operation input unit 55 for the rear door 14. The operation switch 56 is provided on the side surface 2s of the vehicle body 2 near the rear end 2r where the rear door 14 is provided. The PBDECU45 controls the operation of the PBD actuator 41, that is, performs the opening/closing drive control of the back door 14, based on the opening/closing operation request of the back door 14 and the detected movement position Xbd indicated by the operation input signal Scr2.

As shown in fig. 2, when the opening and closing operation request is detected (yes in step 101), the PSDECU35 and the PBDECU45 determine the driving directions of the slide door 4 and the rear door 14 to be driven for opening and closing (step 102). The PSDECU35 and the PBDECU45 execute the opening/closing drive control in the determined drive direction (step 103).

During execution of the opening/closing drive control, the PSDECU35 holds the opening/closing operation request detected in step 101 and the drive direction determined in step 102. Thus, when the new operation input signal Scr1 is not detected, the sliding door 4 driven by the PSD actuator 31 is moved to the fully closed position or the fully open position by the driving control performed by the PSDECU35.

Similarly, the PBDECU45 holds the opening and closing operation request detected in step 101 and the driving direction determined in step 102 during the execution of the opening and closing driving control. Thus, in the case where the new operation input signal Scr2 is not detected, the back door 14 driven by the PBD actuator 41 is moved to the fully closed position or the fully open position by the driving control performed by the PBDECU45.

Further, the sliding door 4 can be opened and closed manually by using the door handle 51 as a grip. Similarly, the back door 14 may be opened or closed manually.

The pinch detection signal Scd1 indicating that the pinch is generated in the sliding door 4 being operated, that is, the sliding door 4 being opened and closed by the execution of the drive control or manually, is input to the PSDECU35. The pinching detection signal Scd1 of the sliding door 4 is, for example, an output signal of a touch sensor, not shown, provided at the front edge portion 4f of the sliding door 4. In the case where the pinching is detected, the reverse drive control of the slide door 4 is performed.

Similarly, the pinch detection signal Scd2 indicating that the rear door 14 is in operation is inputted to the PBDECU45. The sandwiching detection signal Scd2 of the rear door 14 is, for example, an output signal of a touch sensor, not shown, provided in the rear door 14. In the case where the pinching is detected, the reverse drive control of the back door 14 is performed.

As shown in fig. 3, when the ps decu35 and the PBDECU45 detect pinching, respectively (yes in step 201), the drive control of the slide door 4 and the back door 14, which are the objects of opening and closing drive, is stopped (step 202). In the stopped drive control, the ps decu35 and the PBDECU45 perform drive in a direction opposite to the drive direction indicated by the opening and closing operation request, that is, reverse drive control in which the direction of the drive request is reversed (step 203).

(sliding door operation restriction control at the time of rear door opening and closing operation)

Next, a sliding door operation restriction control at the time of a back door opening and closing operation mounted on the vehicle 1 will be described.

As shown in fig. 4, the operation switch 56 provided on the side surface 2s of the vehicle body 2 is disposed near the end position of the guide rail 5b constituting the center rail behind the door opening 3. That is, the operation switch 56 is provided on the side surface 2s of the vehicle body 2 so as to be located on the leading side of the door opening 3 in the opening direction of the slide door 4. Therefore, the user 60 outside the vehicle who operates the operation switch 56 to open or close the rear door 14 may enter the movement track Tsd of the slide door 4.

In view of this, as shown in fig. 5 and 6, in the vehicle 1, based on detection of an operation input to the operation switch 56, an actuation restriction area α including the fully open position Xo of the sliding door 4 is set in the movement range 4X of the sliding door 4. That is, when the operation switch 56 for the rear door 14 is operated, it is estimated that the user 60 who operates the operation switch 56 is highly likely to enter the movement locus Tsd of the slide door 4. Therefore, in the start operation restriction region α, the PSDECU35 does not perform the open drive control of the slide door 4, thereby suppressing interference between the slide door 4 and the off-vehicle user 60 who operates the operation switch 56 for the rear door 14.

The actuation limiting area α is set so as to divide the movement range 4X of the slide door 4 from the fully closed position Xc to the fully open position Xo into two. When the start operation restriction area α is set, the PSDECU35 applies a braking force to the slide door 4 in the start operation restriction area α, and executes a brake control for restricting the start operation.

Specifically, the motor 30 of the PSD actuator 31 is a brushless motor. The braking control performed at the time of setting the start-up restriction region α is performed by braking control of the motor 30, for example, energization control of a conduction phase in which a motor coil called "one-phase energization" or "phase fixed energization" is fixed, regenerative braking control, or the like.

When the start operation restriction area α is set, the control of the opening drive of the slide door 4 by the PSDECU35 is executed only in the start operation permission area β on the fully closed position Xc side of the start operation restriction area α.

That is, when the movement position Xsd of the sliding door 4 is within the opening operation restriction region α, the PSDECU35 does not start the opening drive control. In addition, the slide door 4 that is moved in the opening direction by the execution of the opening drive control enters the start operation restriction region α from the start operation permission region β, so that the PSDECU35 stops the opening drive control. Thus, the slide door 4 stopped in the start operation restriction region α does not move in the opening direction toward the full-open position Xo, that is, does not perform the opening operation.

Specifically, the PSDECU35 maintains the actuation limiting area α set in the movement range 4X of the slide door 4 while detecting the operation input to the operation switch 56 for the rear door 14. The PSDECU35 maintains the opening operation restriction area α until the opening and closing operation of the back door 14 is stopped by the operation input to the operation switch 56, that is, the opening and closing drive control by the PBDECU45 is completed. In addition, even when the condition for maintaining the start-up restriction area α is released, the PSDECU35 maintains the set start-up restriction area α during the start-up of the sliding door 4. That is, even when the operation input to the operation switch 56 is detected once, the operation restriction area α set in the movement range 4X is not released during the operation of the slide door 4. This further effectively suppresses interference between the slide door 4 and the user 60 outside the vehicle who operates the operation switch 56 for the rear door 14.

In addition, when setting the start operation restriction area α, the PSDECU35 changes the size of the set start operation restriction area α according to whether or not the sliding door 4 is in the open operation. The "opening operation" in this case includes the opening direction movement of the slide door 4 by the opening drive control of the psicu 35 and the opening direction movement of the slide door 4 by the manual operation. When the opening operation restriction area α is set during the opening operation of the slide door 4, the PSDECU35 sets the opening operation restriction area α to be narrower than when the opening operation restriction area α is set in a state where the slide door 4 is not being opened, that is, when the slide door is not being operated.

In other words, the second start operation restriction area α2 set in the start operation has a boundary position Xb closer to the full-open position Xo than the first start operation restriction area α1 set in the non-open operation of the sliding door 4 is to the start operation permission area β. Thus, when the start operation restriction area α is set after the start of the opening operation, the sliding door 4 can be opened to a position closer to the fully opened position Xo, as compared with the case where the start operation restriction area α is set at the time of the start of the opening operation.

Specifically, the first actuation restriction area α1 is set to an opening amount of an extent that an occupant can ride down through the door opening 3 when the sliding door 4 is stopped at the boundary position Xb1 with reference to the fully-closed position Xc. The second actuation restriction area α2 is set so as to avoid interference with the user 60 who operates the operation switch 56 entering the movement locus Tsd of the sliding door 4 even when the sliding door 4 is stopped at the boundary position Xb2, based on the fully-opened position Xo.

In more detail, as shown in fig. 1, the PBDECU45 transmits an actuation limiting signal Sld of the sliding door 4 to the PSDECU35, the actuation limiting signal Sld being based on detection of an operation input to the operation switch 56 for the rear door 14. The transmission and reception of the start operation restriction signal Sld is performed using an in-vehicle network, not shown. The psiku 35 performs setting of the actuation limiting area α for the movement range 4X of the sliding door 4 based on the actuation limiting signal Sld.

Specifically, as shown in fig. 7, when an operation input to the operation switch 56 for the rear door 14 is detected (yes in step 301), the PBDECU45 sends an actuation restriction signal Sld for the slide door 4 to the PSDECU35 (step 302). Further, the PBDECU45 executes the processing of steps 301 and 302 and steps 303 to 305 described below at a predetermined operation cycle. Accordingly, while the user 60 outside the vehicle operates the operation switch 56 for the rear door 14, the PBDECU45 continues to transmit the start-up restriction signal Sld to the PSDECU35.

In addition, in the above step 301, when no operation input to the operation switch 56 for the back door 14 is detected (step 301: no), the PBDECU45 determines whether or not the back door 14 is in operation (step 303). Further, when the back door 14 is in operation (yes in step 303), the PBDECU45 determines whether or not the operation of the back door 14 is drive control started by detecting an operation input to the operation switch 56 (step 304). Then, in the case where the operation of the back door 14 is the drive control started based on the detection of the operation input to the operation switch 56 (yes in step 304), the PBDECU45 also executes the processing of step 302 described above. That is, even after the detection of the operation input to the operation switch 56 is interrupted, the PBDECU45 continues to transmit the start operation restriction signal Sld to the PSDECU35 until the drive control of the back door 14 started by the detection of the operation input is completed.

If the back door 14 is not in operation (step 303: no), the PBDECU45 does not transmit the start operation restriction signal Sld (step 305). When the back door 14 is operated with a trigger other than the detection of the operation input to the operation switch 56 (step 304: no), the PBDECU45 does not transmit the operation restriction signal Sld to the PSDECU35.

On the other hand, as shown in fig. 8, when the PSDECU35 receives the opening operation restriction signal Sld (yes in step 401), it is determined whether or not the opening operation restriction area α is set with respect to the movement range 4X of the slide door 4 and whether or not it is being set (step 402). When the start restriction area α has been set (yes in step 402), the start restriction area α in the setting is maintained (step 403), and when the start restriction area α is not set (no in step 402), the setting determination of the start restriction area α is performed (step 404).

Specifically, as shown in fig. 9, in the determination of setting the actuation restriction area α, the PSDECU35 determines whether or not the slide door 4 is in the opening operation (step 501). When the slide door 4 is not in the open operation, that is, when it is not in the open operation (no in step 501), the PSDECU35 sets the first operation restriction area α1 as the operation restriction area α (step 502, see fig. 5). When the slide door 4 is in the open state (yes in step 501), the PSDECU35 sets the second operation restriction area α2 as the operation restriction area α (step 503, see fig. 6).

In addition, as shown in FIG. 8, in the case where the start-up restriction signal Sld is not received (step 401: NO), the PSDECU35 determines whether or not the start-up restriction area α has been set (step 405). When the start restriction area α has been set (yes in step 405), the PSDECU35 executes a release determination of the set start restriction area (step 406).

Specifically, as shown in fig. 10, in the determination of canceling the actuation restriction area α, the PSDECU35 also determines whether or not the slide door 4 is in the opening operation (step 601). When the slide door 4 is not in the open operation, that is, when it is not in the open operation (step 601: no), the PSDECU35 releases the open operation restriction area α set in the movement range 4X of the slide door 4 (step 602). When the slide door 4 is in the open state (yes in step 601), the PSDECU35 maintains the setting of the operation restriction area α with respect to the movement range 4X of the slide door 4 (step 603).

As shown in fig. 11, when the start operation restriction area α is set in the movement range 4X of the slide door 4 (yes in step 701), the PSDECU35 determines whether or not the slide door 4 is located within the start operation restriction area α (step 702). When the slide door 4 is located within the operation restriction area α (yes in step 702), the PSDECU35 determines the moving direction of the slide door 4 (step 703). Then, when the slide door 4 located in the opening operation restriction area α moves in the opening direction or starts to move in the opening direction (yes in step 702), the PSDECU35 executes braking control of the slide door 4 to restrict the opening operation.

Further, when the pinching of the slide door 4 is detected as described above, the PSDECU35 executes the reverse drive control of the slide door 4 (see fig. 3). Then, the following structure is obtained: at the time of execution of the reverse drive control, the slide door 4 is driven in the opening direction even in the case of being located within the actuation restriction region α of the slide door 4.

Specifically, as shown in FIG. 12, when there is a request for opening the slide door 4 (step 801: yes), the PSDECU35 determines whether the slide door 4 is located in the start operation restriction area α (step 802). When the slide door 4 is not located in the operation restriction area α (no in step 802), that is, when it is located in the operation permission area β, the operation drive control of the slide door 4 based on the operation drive request is executed (step 803).

In this case, the PSDECU35 does not execute the braking control of the slide door 4 due to the setting of the actuation limiting region α. Thus, the PSDECU35 starts the new open drive control of the slide door 4 based on the open drive request of step 801, and continues the open drive control in execution.

When the slide door 4 is located in the start operation restriction area α (yes in step 802), the PSDECU35 determines whether or not the start drive request in step 801 is based on the reverse drive control (step 804). In the case where the open drive request is based on the reverse drive control (step 804: yes), the PSDECU35 also drives the slide door 4 in the open direction by executing step 803 described above. In the case where the open drive request is not based on the reverse drive control (step 804: no), the PSDECU35 refutes the open drive request in step 801 (step 805).

That is, when the open drive request is based on the operation input signal Scr1, the PSDECU35 executes the brake control to restrict the opening operation of the slide door 4 in the opening operation restriction region α. Further, the pside 35 does not perform the open drive control of the slide door 4 in the start operation restriction region α. Thus, with respect to the slide door 4 located in the start operation restriction region α, the new start drive control is not started, and the executing start drive control is stopped.

Next, the operation of the present embodiment will be described.

While the user 60 outside the vehicle operates the operation switch 56 for the rear door 14, the opening operation restriction signal Sld is continuously transmitted from the PBDECU45 to the PSDECU35. Further, during the period when the PSDECU35 receives the opening operation restriction signal Sld, the opening operation restriction area α set in the movement range 4X of the slide door 4 is maintained by the reception of the opening operation restriction signal Sld. Accordingly, during the operation of the operation switch 56 for the rear door 14 by the user 60 outside the vehicle, the operation of the slide door 4 in the operation restriction area α is restricted.

The transmission of the opening operation restriction signal Sld from the PBDECU45 to the PSDECU35 is continued until the driving control of the back door 14 started by the detection of the operation input to the operation switch 56 is completed. Thereby, the actuation of the slide door 4 in the actuation limiting region α is limited until the drive control of the rear door 14 based on the operation input to the operation switch 56 ends.

Further, even when the actuation restriction signal Sld by the PBDECU45 is interrupted, the actuation restriction area α set in the movement range 4X of the sliding door 4 is maintained during the opening operation of the sliding door 4. That is, when the PSDECU35 receives the actuation restriction signal Sld sent by the PBDECU45 once, the set actuation restriction area α is not released during the actuation of the sliding door 4. Therefore, with respect to the slide door 4 in the start operation permission region β, the start drive control is stopped by entering the start operation restriction region α, and the brake control is performed. Thus, after the start operation of the slide door 4 is stopped, the start operation restriction area α set in the movement range 4X of the slide door 4 is released based on the interruption of the start operation restriction signal Sld.

Next, effects of the present embodiment will be described.

(1) The sliding door apparatus 10 as a vehicle opening/closing body control apparatus includes a PSD actuator 31 as a driving device, and the PSD actuator 31 drives and opens and closes the sliding door 4 as an opening/closing body. The sliding door apparatus 10 further includes a PSDECU35 that controls the operation of the PSD actuator 31. The PSDECU35 has a function as a drive control unit 70a that performs drive control of the slide door 4 by controlling the operation of the PSD controller 31. The PSDECU35 also has a function as a moving position detecting unit 70b for detecting the moving position Xsd of the sliding door 4. An operation switch 56 for the rear door 14 is provided at a position on the front side of the door opening 3 in the opening direction of the slide door 4 on the side surface 2s of the vehicle body 2 on which the door opening 3 is provided as an opening opened and closed by the slide door 4. Further, the PSDECU35 has a function of setting the actuation limiting area setting portion 70c including the actuation limiting area α of the fully open position Xo of the slide door 4 in the movement range 4X of the slide door 4 based on the detection of the operation input to the operation switch 56. When the start operation restriction area α is set, the PSDECU35 restricts the opening operation of the slide door 4 in the start operation restriction area α.

When the operation switch 56 located on the leading side of the door opening 3 in the opening direction of the sliding door 4 is operated, the user 60 who operates the operation switch 56 may enter the movement trajectory Tsd of the sliding door 4. According to the above-described structure, in this case, by setting the actuation restriction area α including the full-open position Xo, the actuation of the sliding door 4 within the actuation restriction area α is restricted. This can suppress interference between the slide door 4 and the user 60 outside the vehicle who operates the operation switch 56 provided in the opening direction of the slide door 4. Further, the user 60 who operates the operation switch 56 for the rear door 14 can not feel a psychological feeling of pressure about the sliding door 4 to approach.

(2) When the start operation restriction area α is set, the PSDECU35 does not execute the open drive control of the slide door 4 in the start operation restriction area α.

According to the above configuration, the opening operation of the slide door 4 moving in the start operation restriction area α is restricted by the execution of the opening drive control, and the start of the opening operation of the slide door 4 located in the start operation restriction area α can be restricted by the execution of the opening drive control. This can suppress interference between the user 60 who operates the operation switch 56 and the slide door 4.

(3) When the actuation limiting area α is set, the PSDECU35 executes braking control for limiting the opening of the slide door 4 by applying a braking force to the slide door 4 in the opening limiting area α.

According to the above configuration, the opening operation of the sliding door 4 moving in the operation restriction area α is restricted, including the case of manual operation by the occupant, and the start of the opening operation can be restricted for the sliding door 4 located in the operation restriction area α. This can suppress interference between the user 60 operating the operation switch 56 provided in the opening direction of the slide door 4 and the slide door 4.

(4) The psidu 35 maintains the actuation restriction area α set in the movement range 4X of the slide door 4 during detection of the operation input to the operation switch 56.

While the operation switch 56 is operated, it is estimated that there is a high possibility that the user 60 who operates the operation switch 56 enters the movement locus Tsd of the slide door 4. Therefore, according to the above configuration, interference between the user 60 operating the operation switch 56 provided in the opening direction of the slide door 4 and the slide door 4 can be more effectively suppressed.

(5) The PSDECU35 is maintained in the actuation limiting region α set in the movement range 4X of the slide door 4 until the opening and closing operation of the back door 14, which is the in-vehicle device that starts to operate by the operation input to the operation switch 56, is stopped.

During the opening/closing operation of the rear door 14, which is started by the operation of the operation switch 56, it is estimated that the user 60 who operates the operation switch 56 is highly likely to enter the movement trajectory Tsd of the slide door 4. Therefore, according to the above configuration, interference between the user 60 operating the operation switch 56 provided in the opening direction of the slide door 4 and the slide door 4 can be more effectively suppressed.

(6) The PSDECU35 maintains the actuation restricting area α set in the movement range 4X of the slide door 4 during execution of the opening drive control even when the condition for maintaining the opening actuation restricting area α described in (4) and (5) is released during execution of the opening drive control.

According to the above configuration, even when an operation input to the operation switch 56 is detected once, the operation restriction area α set in the movement range 4X is not released during the operation of the slide door 4. In addition, the sliding door 4 that moves in the opening direction in the actuation permission area β is restricted from opening by the sliding door 4 entering the opening restriction area α. Then, when the operation input to the operation switch 56 is not detected after the start operation of the slide door 4 is stopped, the start operation restriction area α set in the movement range 4X is released.

As a result, the user 60 who operates the operation switch 56 can perform the opening operation of the sliding door 4 in a state in which the possibility of entering the movement locus Tsd of the sliding door 4 is reduced. This can more effectively suppress interference between the user 60 who operates the operation switch 56 provided in the opening direction of the slide door 4 and the slide door 4.

(7) The opening restriction area α includes a first opening restriction area α1 and a second opening restriction area α2, the first opening restriction area α1 being set in a state where the sliding door 4 is not being opened, and the second opening restriction area α2 being set in the opening of the sliding door 4. The second actuation limiting area α2 is narrower than the first actuation limiting area α1.

According to the above configuration, even when the operation switch 56 is operated immediately after the start of the opening operation of the slide door 4, for example, the operation of the slide door 4 can be continued within a range in which interference between the user 60 who has operated the operation switch 56 and the slide door 4 can be suppressed. That is, in the start operation restriction area α, if interference between the user 60 who enters the movement locus Tsd and the sliding door 4 is likely to occur, the possibility that the operation switch 56 for the rear door 14 is operated while the sliding door 4 is being opened in the start operation restriction area α is low. Therefore, according to the above-described configuration, even in the case where the operation switch 56 is operated immediately after the start of the opening operation, the interference can be suppressed, and the operation of the sliding door 4 can be continued at least by an amount corresponding to the difference between the first operation restriction region α1 and the second operation restriction region α2. This can avoid the occurrence of a sudden stop of the slide door 4 immediately after the start of the opening operation, and ensure a high quality feeling.

(8) The psidecu 35 has a function as a detection unit 70 for detecting the pinching occurring in the sliding door 4. When the pinching of the slide door 4 is detected, the psicu 35 executes reverse drive control for reversing the drive direction of the slide door 4. In addition, the PSDECU35 drives the slide door 4 in the opening direction even in the start operation restriction region α at the time of execution of the reverse drive control.

According to the above configuration, when the pinching of the sliding door 4 is detected, the pinching is released preferentially by the execution of the reverse drive control. This ensures high safety.

The above embodiment can be modified as follows. The above-described embodiments and the following modifications can be combined and implemented within a range that is not technically contradictory.

In the above embodiment, the PSDECU35 receives the actuation restriction signal Sld transmitted from the PBDECU45, thereby setting the opening restriction area α in the movement range 4X of the sliding door 4. However, the present invention is not limited to this, and a detection signal for the operation input to the operation switch 56 for the back gate 14 and a driving state signal of the back gate 14 by the PBDECU45 may be input to the PSDECU35. Thus, the following structure is also possible: in the PSDECU35, the entry possibility determination of the movement locus Tsd of the slide door 4 by the user 60 corresponding to the transmission of the start-up restriction signal Sld by the PBDECU45 is performed.

That is, detection of the operation input of the operation switch 56 may also be performed by the psidu 35. The following structure may be adopted: the determination as to whether or not the setting of the operation restriction area α is required based on the detected start of the operation input is performed solely by the psicu 35, and the set start operation restriction area α is maintained.

The conditions for maintaining the actuation restriction area α set in the movement range 4X of the slide door 4 may be arbitrarily changed.

In the above embodiment, the setting positions of the boundary position Xb1 of the first actuation restriction area α1 and the boundary position Xb2 of the second actuation restriction area α2 may be arbitrarily changed. The structure may also be as follows: when the opening operation restriction area α is set during the operation of the sliding door 4 and when the opening operation restriction area α is set during the non-operation, the size of the opening operation restriction area α set in the movement range 4X of the sliding door 4 is equal.

In the above embodiment, the configuration of the operation switch 56 provided to the vehicle body 2 so as to be located on the leading side of the door opening 3 in the opening direction of the slide door 4 may be arbitrarily set. For example, the button type may be a slide type. Further, a touch sensor may be used. Further, for example, a non-contact switch such as a capacitance type switch may be used.

In the above embodiment, the braking control of the sliding door 4 located in the start operation restriction region α is performed by the braking control of the motor 30 as the driving source of the PSD actuator 31. However, the braking force may be generated by a mechanical structure such as a structure that uses the reverse input resistance characteristic of the reduction mechanism applied to the PSD actuator 31 by, for example, connecting an electromagnetic clutch. The structure of the motor 30 as a driving source may be arbitrarily changed, and is, for example, a brush-attached dc motor or the like.

The magnitude of the braking force applied to the slide door 4 in the actuation restriction region α by the execution of the braking control may be arbitrarily set. For example, the forced power that the sliding door 4 cannot be opened may be applied by manual operation of the occupant, or the braking force that is a large operation force required by the occupant to open the sliding door 4 may be applied manually. For example, in a case where only the door handle 51 for emergency is provided to the slide door 4, the slide door 4 may be opened by the opening drive control mainly performed by the PSDECU35, or may be braked to a degree that the stop position of the slide door 4 is maintained. The structure may also be as follows: the opening operation of the slide door 4 in the actuation restriction area α is restricted by the execution of the position control without performing explicit brake control.

In the above embodiment, the sliding door 4 for opening and closing the door opening 3 provided on the side surface 2s of the vehicle body 2 is used as an opening and closing body, and the vehicle opening and closing body control device is embodied as the sliding door device 10 including the PSDECU35 and the PSD actuator 31 for performing the opening and closing driving control of the sliding door 4. An operation switch 56 for the rear door 14 is provided at a position on the front side of the door opening 3 in the opening direction of the slide door 4 on the side surface 2s of the vehicle body 2 where the door opening 3 is provided.

However, the present invention is not limited to this, and may be applied to, for example, a vehicle opening/closing body control device such as a sunroof device, which is a device for controlling an opening/closing body other than a sliding door. Further, the operation switch 56 provided in the opening direction of the opening/closing body may be an operation switch 56 other than the operation input unit 55 of the rear door 14. The in-vehicle device that starts operation by the operation input to the operation switch 56 may not necessarily be a device that drives a movable member such as the back door 14.

The PSDECU35 and the PBDECU45 can be configured as (1) one or more processors that operate according to a computer program (software), (2) one or more dedicated hardware circuits such as dedicated hardware (application specific integrated circuits: ASICs) that execute at least some of the various processes, or (3) a processing circuit (processing circuitry) that includes a combination of these. The processor includes a CPU, a memory such as a RAM and a ROM, and the memory stores program codes or instructions configured to cause the CPU to execute processing. Memory, i.e., non-transitory computer readable media, encompasses any available media that can be accessed by a general purpose or special purpose computer.
