[0023] Hereinafter, an embodiment of the vehicle opening and closing body control device will be described with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the vehicle 1 of this embodiment includes a sliding door 4, which opens and closes a door opening 3 located on the side 2s of the vehicle body 2. Specifically, the vehicle 1 is provided with a door opening 3 located along the front-rear direction of the vehicle 1. Figure 1 The sliding door 4 is supported on the side 2s of the vehicle body 2 via the guide rails 5 extending in the left-right direction and the guide roller units 6a-6c connected to these guide rails 5 respectively.

[0025] These guide rails 5 and guide roller units 6 can be relatively displaced relative to the connection position of the guide roller unit 6 with respect to the guide rail 5 along the extension direction of the guide rail 5. Thus, a sliding door device 10 is formed that can perform the opening and closing operation of the sliding door 4 provided at the door opening 3.

[0026] Sliding door 4 is configured to allow access to the front side of the vehicle ( Figure 1 The sliding door 4 is configured to move to the left side of the vehicle (same as the right side in the figure), so that the occupants of the vehicle 1 can get in and out through the door opening 3.

[0027] In addition, the vehicle 1 has a rearward-opening door opening 13 located at the rear end 2r of the vehicle body 2. A so-called pop-up rear door 14 is provided in the door opening 13.

[0028] The rear door 14 opens upwards using the upper part of the door opening 13 as a pivot point. A pair of retractable, shaft-shaped support devices 15 are provided at both ends of the door opening 13 in the width direction. The axial ends of the pair of support devices 15 are rotatably connected 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 movement of the support devices 15. The rear door device 20 has a structure known as a rear hatch.

[0029] Furthermore, vehicle 1 is equipped with a PSD actuator 31 that uses an electric motor 30 as a drive source to drive the opening and closing of the sliding door 4, and a PSDECU 35 that controls the operation of the PSD actuator 31. Further, vehicle 1 is equipped with a PBD actuator 41 that uses an electric motor 40 as a drive source to drive the opening and closing of the rear door 14, and a PBDECU 45 that controls the operation of the PBD actuator 41. Thus, the sliding door assembly 10 and the rear door assembly 20 respectively have the structure of a so-called powered sliding door and a powered rear door, which are opened and closed by an electric motor.

[0030] Specifically, a pulse signal Sp1 synchronized with the action of the PSD actuator 31 is input to the PSDECU 35. The PSDECU 35 detects the movement position Xsd of the sliding door 4, which opens and closes based on the driving force of the PSD actuator 31, by counting the pulse signal Sp1.

[0031] Similarly, a pulse signal Sp2 synchronized with the action of the PBD actuator 41 is also input to the PBDECU45. The PBDECU45 detects the movement position Xbd of the rear door 14, which opens and closes based on the driving force of the PBD actuator 41, by counting the pulse signals Sp2.

[0032] Furthermore, the movement position Xsd of the sliding door 4 is represented, for example, by its fully closed position or by a pulse count value based on the fully closed position. Similarly, the movement position Xbd of the rear door 14 is represented by its fully closed position or by a pulse count value based on the fully closed position.

[0033] Additionally, the PSDECU35 receives an operation input signal Scr1 from the operation input unit 53, which is located on the door handle 51 of the sliding door 4 and the portable device 52 held by the user inside the vehicle and in the vehicle 1. Based on the opening and closing action requirements of the sliding door 4 indicated by the operation input signal Scr1 and the detected movement position Xsd, the PSDECU35 controls the operation of the PSD actuator 31, that is, performs the opening and closing drive control of the sliding door 4.

[0034] Similarly, the PSDECU35 also inputs an operation input signal Scr2 to the operation input unit 55 located on the rear door 14, the vehicle body 2, and the portable device 52. Specifically, the vehicle 1 has an operation switch 56 that serves as the operation input unit 55 for the rear door 14. The operation switch 56 is located near the rear end 2r where the rear door 14 is located, and is located on the side 2s of the vehicle body 2. Based on the opening and closing action requirement of the rear door 14 indicated by the operation input signal Scr2 and the detected movement position Xbd, the PBDECU45 controls the operation of the PBD actuator 41, that is, performs the opening and closing drive control of the rear door 14.

[0035] like Figure 2 As shown, when PSDECU35 and PBDECU45 detect an opening / closing action requirement (step 101: Yes), they determine the driving direction of the sliding door 4 and rear door 14, which are the objects of the opening / closing drive (step 102). Then, PSDECU35 and PBDECU45 execute the opening / closing drive control in the determined driving direction (step 103).

[0036] During the execution of the opening and closing drive control, the PSDECU35 maintains the opening and closing action requirements detected in step 101 and the drive direction determined in step 102. Thus, in the absence of a new operation input signal Scr1, the sliding door 4 driven by the PSD actuator 31 moves to the fully closed or fully open position through the drive control executed by the PSDECU35.

[0037] Similarly, during the execution of the opening and closing drive control, the PBDECU45 maintains the opening and closing action requirements detected in step 101 and the drive direction determined in step 102. Thus, in the absence of a new operation input signal Scr2, the rear door 14 driven by the PBD actuator 41 moves to the fully closed or fully open position through the drive control executed by the PBDECU45.

[0038] Furthermore, the sliding door 4 can be manually opened and closed by using the door handle 51 as a grip. Similarly, the rear door 14 can also be manually opened and closed.

[0039] Additionally, the input to PSDECU35 indicates that a clamping detection signal Scd1 has been generated in the sliding door 4, which is opened and closed by drive control or manually, i.e., in operation. Furthermore, the clamping detection signal Scd1 of the sliding door 4 can be, for example, the output signal of a touch sensor (not shown) provided at the leading edge 4f of the sliding door 4. If clamping is detected, reverse drive control of the sliding door 4 is executed.

[0040] Similarly, the input to PBDECU45 indicates that a clamping detection signal Scd2 is generated in the rear door 14 during operation. Furthermore, the clamping detection signal Scd2 of the rear door 14 can be, for example, the output signal of a touch sensor (not shown) provided on the rear door 14. Upon detection of clamping, reverse drive control of the rear door 14 is executed.

[0041] like Figure 3 As shown, when PSDECU35 and PBDECU45 detect clamping (step 201: Yes), the drive control of the sliding door 4 and rear door 14, which are the objects of opening and closing, is stopped (step 202). In this stopped drive control, PSDECU35 and PBDECU45 respectively execute drive in the opposite direction to the drive direction indicated by the opening and closing action requirement, that is, reverse drive control that reverses the drive requirement direction (step 203).

[0042] (Sliding door movement restriction control during rear door opening and closing operation)

[0043] Next, the control of sliding door movement restriction during the operation of the rear door switch installed on vehicle 1 will be explained.

[0044] like Figure 4 As shown, the operation switch 56, located on the side 2s of the vehicle body 2, is positioned near the end of the guide rail 5b that forms the central track behind the door opening 3. That is, the operation switch 56 is positioned on the side 2s of the vehicle body 2 in the opening direction of the sliding door 4, prior to the door opening 3. Therefore, a user 60 outside the vehicle who operates the operation switch 56 to open or close the rear door 14 has the possibility of entering the movement trajectory Tsd of the sliding door 4.

[0045] In view of this, such as Figure 5 and Figure 6 As shown, in vehicle 1, based on the detection of the operation input of the operation switch 56, an opening action restriction region α is set within the movement range 4X of the sliding door 4, including the fully open position Xo of the sliding door 4. That is, when the operation switch 56 for the rear door 14 is operated, it is presumed that the user 60 who operated the operation switch 56 is highly likely to enter the movement trajectory Tsd of the sliding door 4. Therefore, within the opening action restriction region α, the PSDECU 35 does not perform the opening drive control of the sliding door 4, thereby suppressing interference between the user 60 outside the vehicle who operates the operation switch 56 for the rear door 14 and the sliding door 4.

[0046] The opening action restriction zone α is set in such a way that the movement range 4X of the sliding door 4 from the fully closed position Xc to the fully open position Xo is divided in two. When the opening action restriction zone α is set, the PSDECU35 applies braking force to the sliding door 4 within the opening action restriction zone α to perform braking control that restricts the opening action.

[0047] Specifically, the motor 30 of the PSD actuator 31 is a brushless motor. Furthermore, the braking control performed when the aforementioned start-up restriction region α is set is performed through braking control of the motor 30, such as energizing control of the energized phase of the motor coil which is fixed and referred to as "one-phase energized" or "phase fixed energized", or regenerative braking control.

[0048] Furthermore, when the opening action restriction zone α is set, the opening drive control of the sliding door 4 performed by PSDECU35 is only executed in the opening action permission zone β, which is closer to the fully closed position Xc than the opening action restriction zone α.

[0049] That is, when the sliding door 4's moving position Xsd is within the opening action restriction region α, the PSDECU 35 does not initiate opening drive control. Furthermore, when the sliding door 4, moving in the opening direction due to the execution of opening drive control, enters the opening action restriction region α from the opening action permission region β, the PSDECU 35 stops opening drive control. Therefore, the sliding door 4, stopped within the opening action restriction region α, does not move in the opening direction toward the fully open position Xo, i.e., it does not perform an opening action.

[0050] In detail, while the PSDECU35 detects an operation input to the operating switch 56 for the rear door 14, it maintains the opening action restriction area α set within the movement range 4X of the sliding door 4. Furthermore, the PSDECU35 maintains the opening action restriction area α until the opening and closing operation of the rear door 14 is stopped by the operation input to the operating switch 56, i.e., until the opening and closing drive control performed by the PBDECU45 ends. Moreover, even if the condition for maintaining the opening action restriction area α is released, the PSDECU35 maintains the set opening action restriction area α during the opening of the sliding door 4. That is, even if an operation input to the operating switch 56 is detected only once, the opening action restriction area α set within the movement range 4X is not released during the opening of the sliding door 4. This further effectively suppresses interference between the user 60 outside the vehicle operating the operating switch 56 for the rear door 14 and the sliding door 4.

[0051] Furthermore, when setting the opening action restriction area α, the PSDECU35 changes the size of the set opening action restriction area α depending on whether the sliding door 4 is in the opening action. In this case, "opening action" includes both the opening direction movement of the sliding door 4 controlled by the PSDECU35's opening drive and the opening direction movement of the sliding door 4 manually. When the PSDECU35 sets the opening action restriction area α during the opening action of the sliding door 4, it sets the opening action restriction area α to be narrower than when the sliding door 4 is not in the opening action state—that is, compared to when it is not in the opening action state.

[0052] In other words, the second opening action restriction area α2 set during the opening action has a boundary position Xb with the opening action permitted area β. This boundary position Xb is closer to the fully open position Xo than the first opening action restriction area α1 set when the sliding door 4 is not in the opening action. Therefore, compared to the case where the opening action restriction area α is set at the moment the opening action begins, when the opening action restriction area α is set after the opening action begins, the sliding door 4 can open to a position closer to the fully open position Xo.

[0053] Specifically, the first opening restriction area α1 is set to ensure, based on the fully closed position Xc, the opening amount sufficient to allow an occupant to board or alight via the door opening 3 when the sliding door 4 is stopped at the boundary position Xb1. The second opening restriction area α2 is set to prevent interference with the user 60 operating the operating switch 56 within the movement trajectory Tsd of the sliding door 4, even when the sliding door 4 is stopped at the boundary position Xb2, based on the fully open position Xo.

[0054] More specifically, such as Figure 1 As shown, PBDECU45 sends an opening restriction signal Sld for the sliding door 4 to PSDECU35. This opening restriction signal Sld is based on the detection of the operation input of the operation switch 56 for the rear door 14. Furthermore, the transmission and reception of the opening restriction signal Sld are performed using an in-vehicle network (not shown). Based on the opening restriction signal Sld, PSDECU35 sets the opening restriction area α for the movement range 4X of the sliding door 4.

[0055] Specifically, such as Figure 7As shown, when the PBDECU45 detects an operation input to the operating switch 56 for the rear door 14 (step 301: Yes), it sends an opening action restriction signal Sld for the sliding door 4 to the PSDECU35 (step 302). Furthermore, the PBDECU45 executes steps 301 and 302, and steps 303 to 305 as described below, with a predetermined operation cycle. Thus, while the user 60 outside the vehicle operates the operating switch 56 for the rear door 14, the PBDECU45 continues to send the opening action restriction signal Sld to the PSDECU35.

[0056] Furthermore, in step 301 above, if no operation input to the operation switch 56 for the rear door 14 is detected (step 301: No), PBDECU45 determines whether the rear door 14 is in operation (step 303). Further, if the rear door 14 is in operation (step 303: Yes), PBDECU45 determines whether the operation of the rear door 14 is drive control initiated based on the detection of operation input to the operation switch 56 (step 304). Then, if the operation of the rear door 14 is drive control initiated based on the detection of operation input to the operation switch 56 (step 304: Yes), PBDECU45 also executes the processing in step 302 above. That is, even after the detection of operation input to the operation switch 56 is interrupted, PBDECU45 continues to send the opening operation restriction signal Sld to PSDECU35 until the drive control of the rear door 14 initiated by the detection of operation input ends.

[0057] Furthermore, PBDECU45 does not send the opening action restriction signal Sld when the rear door 14 is not in operation (step 303: No) (step 305). PBDECU45 also does not send the opening action restriction signal Sld to PSDECU35 when the rear door 14 is activated by a trigger other than the detection of an operation input to the operation switch 56 (step 304: No).

[0058] On the other hand, such as Figure 8 As shown, when PSDECU35 receives the opening action restriction signal Sld (step 401: Yes), it determines whether to set the opening action restriction area α relative to the movement range 4X of the sliding door 4, and whether it is being set (step 402). If the opening action restriction area α has been set (step 402: Yes), the set opening action restriction area α is maintained (step 403). If it is not set (step 402: No), the setting determination of the opening action restriction area α is performed (step 404).

[0059] Specifically, such as Figure 9As shown, in the determination of the opening action restriction area α, PSDECU35 determines whether the sliding door 4 is in the opening action (step 501). If the sliding door 4 is not in the opening action, that is, in the non-opening action (step 501: No), PSDECU35 sets the first opening action restriction area α1 as the opening action restriction area α (step 502, refer to...). Figure 5 When the sliding door 4 is in the opening action (step 501: Yes), PSDECU35 sets the second opening action restriction area α2 as the opening action restriction area α (step 503, refer to...). Figure 6 ).

[0060] In addition, such as Figure 8 As shown, if the PSDECU35 does not receive the opening action restriction signal Sld (step 401: No), it determines whether the opening action restriction region α has been set (step 405). If the opening action restriction region α has been set (step 405: Yes), the PSDECU35 performs the determination to release the set opening action restriction region (step 406).

[0061] Specifically, such as Figure 10 As shown, in the determination of releasing the opening action restriction area α, PSDECU35 also determines whether the sliding door 4 is in the opening action (step 601). If the sliding door 4 is not in the opening action, that is, in the non-opening action (step 601: No), PSDECU35 releases the opening action restriction area α set in the movement range 4X of the sliding door 4 (step 602). If the sliding door 4 is in the opening action (step 601: Yes), PSDECU35 maintains the setting of the opening action restriction area α relative to the movement range 4X of the sliding door 4 (step 603).

[0062] In addition, such as Figure 11 As shown, when the PSDECU35 sets an opening action restriction area α within the movement range 4X of the sliding door 4 (step 701: Yes), it determines whether the sliding door 4 is located within the opening action restriction area α (step 702). When the sliding door 4 is located within the opening action restriction area α (step 702: Yes), the PSDECU35 determines the movement direction of the sliding door 4 (step 703). Then, when the sliding door 4, located within the opening action restriction area α, moves in the opening direction or begins to move in the opening direction (step 702: Yes), the PSDECU35 performs braking control of the sliding door 4 to restrict the opening action.

[0063] Furthermore, when PSDECU35 detects the sliding door 4 being clamped as described above, it executes reverse drive control of the sliding door 4 (see reference). Figure 3Then, it becomes the following structure: when the reverse drive control is executed, the sliding door 4 is driven in the opening direction even when it is located within the opening action restriction area α of the sliding door 4.

[0064] Specifically, such as Figure 12 As shown, when there is a request to open the sliding door 4 (step 801: Yes), PSDECU35 determines whether the sliding door 4 is located in the opening action restriction region α (step 802). If the sliding door 4 is not located in the opening action restriction region α (step 802: No), that is, if it is located in the opening action permission region β, it performs the opening drive control of the sliding door 4 based on the opening drive request (step 803).

[0065] In this case, PSDECU35 does not perform braking control of the sliding door 4 caused by the setting of the opening action restriction area α. Therefore, based on the opening drive requirement in step 801 above, PSDECU35 starts new opening drive control of the sliding door 4 and continues the ongoing opening drive control.

[0066] Furthermore, if the sliding door 4 is located in the opening action restriction region α (step 802: Yes), the PSDECU35 then determines whether the opening drive request in step 801 is based on reverse drive control (step 804). If the opening drive request is based on reverse drive control (step 804: Yes), the PSDECU35 also drives the sliding door 4 in the opening direction by executing step 803. If the opening drive request is not based on reverse drive control (step 804: No), the PSDECU35 rejects the opening drive request in step 801 (step 805).

[0067] That is, when the opening drive requirement is based on the operation input signal Scr1, PSDECU35 performs braking control to limit the opening action of the sliding door 4 within the opening action restriction area α. Furthermore, PSDECU35 does not perform opening drive control for the sliding door 4 within the opening action restriction area α. Therefore, for the sliding door 4 located in the opening action restriction area α, no new opening drive control is initiated, and the ongoing opening drive control is stopped.

[0068] Next, the function of this embodiment will be explained.

[0069] While the user 60 outside the vehicle operates the control switch 56 for the rear door 14, an opening action restriction signal Sld continues to be sent from the PBDECU 45 to the PSDECU 35. Furthermore, while the PSDECU 35 receives the opening action restriction signal Sld, the opening action restriction area α set within the movement range 4X of the sliding door 4 is maintained by the receipt of the opening action restriction signal Sld. Therefore, while the user 60 outside the vehicle operates the control switch 56 for the rear door 14, the opening action of the sliding door 4 within the opening action restriction area α is restricted.

[0070] Furthermore, the opening action restriction signal Sld continues to be sent from PBDECU45 to PSDECU35 until the drive control of the rear door 14, which was initiated by detecting the operation input of the operation switch 56, ends. Thus, the opening action of the sliding door 4 in the opening action restriction area α is restricted until the drive control of the rear door 14 based on the operation input of the operation switch 56 ends.

[0071] Furthermore, even if the opening action restriction signal Sld based on PBDECU45 is interrupted, the opening action restriction area α set within the movement range 4X of the sliding door 4 is maintained during the opening action of the sliding door 4. That is, as long as PSDECU35 receives the opening action restriction signal Sld sent by PBDECU45 even once, the set opening action restriction area α is not released during the opening action of the sliding door 4. Therefore, for the sliding door 4 operating in the opening action permission area β, the opening drive control stops due to entering the opening action restriction area α, and braking control is executed. Thus, after the opening action of the sliding door 4 stops, the opening action restriction area α set within the movement range 4X of the sliding door 4 is released based on the interruption of the opening action restriction signal Sld.

[0072] Next, the effects of this embodiment will be explained.

[0073] (1) The sliding door device 10, which is a vehicle opening and closing control device, includes a PSD actuator 31 as a drive unit, which drives the sliding door 4, which is the opening and closing body, to open and close. The sliding door device 10 also includes a PSDECU 35 that controls the operation of the PSD actuator 31. The PSDECU 35 functions as a drive control unit 70a that performs drive control of the sliding door 4 by controlling the operation of the PSD controller 31. The PSDECU 35 also functions as a movement position detection unit 70b that detects the movement position Xsd of the sliding door 4. On the side 2s of the vehicle body 2, where a door opening portion 3, which is the opening portion opened and closed by the sliding door 4, an operation switch 56 for the rear door 14 is provided at a position on the leading side of the door opening portion 3 in the opening direction of the sliding door 4. Furthermore, the PSDECU 35 has a function of setting an opening action restriction area setting unit 70c, which, based on the detection of the operation input to the operation switch 56, sets an opening action restriction area α, including the fully open position Xo of the sliding door 4, within the movement range 4X of the sliding door 4. Furthermore, when the opening action restriction area α is set, PSDECU35 restricts the opening action of the sliding door 4 in the opening action restriction area α.

[0074] When the operating 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 operating the operating switch 56 may enter the movement trajectory Tsd of the sliding door 4. According to the above structure, in this case, by setting an opening action restriction area α that includes the fully open position Xo, the opening action of the sliding door 4 within the opening action restriction area α is restricted. As a result, interference between the user 60 outside the vehicle operating the operating switch 56 provided in the opening direction of the sliding door 4 and the sliding door 4 can be suppressed. In addition, the user 60 operating the operating switch 56 for the rear door 14 can avoid giving the user a psychological sense of pressure that the sliding door 4 is about to approach.

[0075] (2) When the opening action restriction area α is set, PSDECU35 does not execute the opening drive control of the sliding door 4 in the opening action restriction area α.

[0076] According to the above structure, the opening action of the sliding door 4, which moves within the opening action restriction region α, can be restricted by the execution of the opening drive control, and the start of the opening action can be restricted for the sliding door 4 located within the opening action restriction region α. ​​Thus, interference between the user 60, who operates the operating switch 56, and the sliding door 4 can be suppressed.

[0077] (3) When the opening action restriction area α is set, PSDECU35 performs braking control to apply braking force to the sliding door 4 within the opening action restriction area α to restrict the opening action of the sliding door 4.

[0078] According to the above structure, including the case of manual operation by the occupant, the opening action of the sliding door 4, which moves within the opening action restriction area α, can be restricted, and the initiation of the opening action can be limited for the sliding door 4 located within the opening action restriction area α. Thus, interference between the user 60, who operates the operation switch 56 provided in the opening direction of the sliding door 4, and the sliding door 4 can be suppressed.

[0079] (4) During the period when the PSDECU35 detects the operation input to the operation switch 56, it maintains the sliding door 4 within the opening action restriction area α set in the movement range 4X of the sliding door 4.

[0080] During the period when the operation switch 56 is operated, it is presumed that the user 60 who operates the operation switch 56 is highly likely to enter the movement trajectory Tsd of the sliding door 4. Therefore, according to the above structure, interference between the user 60 who operates the operation switch 56 provided in the opening direction of the sliding door 4 and the sliding door 4 can be suppressed more effectively.

[0081] (5) The PSDECU35 maintains the opening action restriction area α set in the movement range 4X of the sliding door 4 until the opening and closing action of the vehicle device, namely the rear door 14, which is started by the operation input of the operation switch 56, stops.

[0082] During the opening and closing of the rear door 14, which is activated by operating the operation switch 56, it is presumed that the user 60 operating the operation switch 56 is more likely to enter the movement trajectory Tsd of the sliding door 4. Therefore, according to the above structure, interference between the user 60 operating the operation switch 56, which is located in the opening direction of the sliding door 4, and the sliding door 4 can be suppressed more effectively.

[0083] (6) During the execution of the opening drive control of the sliding door 4, even if the conditions for maintaining the opening action restriction area α described in (4) and (5) above are released, the PSDECU35 maintains the opening action restriction area α set in the movement range 4X of the sliding door 4 during the execution of the opening drive control.

[0084] According to the above structure, even if only one operation input to the operation switch 56 is detected, the opening action restriction area α set in the movement range 4X will not be released during the opening action of the sliding door 4. Furthermore, for the sliding door 4 moving in the opening direction within the opening action permission area β, the opening action is restricted by the sliding door 4 entering the opening action restriction area α. Then, after the opening action of the sliding door 4 stops, if no operation input to the operation switch 56 is detected, the opening action restriction area α set in the movement range 4X is released.

[0085] As a result, the sliding door 4 can be opened when the likelihood of the user 60 operating the operating switch 56 entering the movement trajectory Tsd of the sliding door 4 is reduced. Therefore, interference between the user 60 operating the operating switch 56, which is located in the opening direction of the sliding door 4, and the sliding door 4 can be more effectively suppressed.

[0086] (7) The opening action restriction area α includes a first opening action restriction area α1 and a second opening action restriction area α2. The first opening action restriction area α1 is set when the sliding door 4 is not opened, and the second opening action restriction area α2 is set when the sliding door 4 is opened. The second opening action restriction area α2 is narrower than the first opening action restriction area α1.

[0087] According to the above structure, for example, even if the operation switch 56 is operated after the sliding door 4 has just started to open, the opening action of the sliding door 4 can continue within a range that can suppress interference between the user 60 who operated the operation switch 56 and the sliding door 4. That is, if interference between the user 60 and the sliding door 4 is likely to occur within the opening action restriction region α, the probability of the operation switch 56 for the rear door 14 being operated is low during the opening action of the sliding door 4 within the opening action restriction region α. ​​Therefore, according to the above structure, even if the operation switch 56 is operated after the opening action has just started, interference can be suppressed, and the opening action of the sliding door 4 can continue at least by an amount equivalent to the difference between the first opening action restriction region α1 and the second opening action restriction region α2. Thus, the situation where the sliding door 4 suddenly stops after the opening action has just started can be avoided, ensuring a high-quality experience.

[0088] (8) The PSDECU35 has the function of a detection unit 70 for detecting clamping in the sliding door 4. When the PSDECU35 detects clamping in the sliding door 4, it executes reverse drive control to reverse the drive direction of the sliding door 4. Furthermore, when the reverse drive control is executed, the PSDECU35 drives the sliding door 4 in the opening direction even in the opening operation restriction area α.

[0089] Based on the above structure, when the sliding door 4 is detected to be clamped, the clamping is preferentially released by executing the reverse drive control. This ensures high safety.

[0090] Furthermore, the above-described embodiments can be implemented with modifications as follows. The above-described embodiments and the following modifications can be combined with each other within the scope of technical inconsistency.

[0091] In the above embodiment, the PSDECU35 receives the opening action restriction signal Sld sent by the PBDECU45, thereby setting the opening action restriction area α within the movement range 4X of the sliding door 4. However, it is not limited to this; the PSDECU35 may also input a detection signal of the operation input of the operation switch 56 for the rear door 14, and a drive state signal of the rear door 14 based on the PBDECU45. Thus, it may also be structured such that the PSDECU35 performs an entry probability determination of the user 60's movement trajectory Tsd towards the sliding door 4, which is equivalent to the PBDECU45 sending the opening action restriction signal Sld.

[0092] That is, the detection of the operation input of the operation switch 56 can also be performed by the PSDECU35. Furthermore, it can also be structured as follows: the PSDECU35 independently determines whether the setting of the opening action restriction area α based on the detection of the operation input is required, and determines whether the set opening action restriction area α is maintained.

[0093] Furthermore, the conditions for maintaining the opening action restriction area α set within the movement range 4X of the sliding door 4 can be arbitrarily changed.

[0094] In the above embodiments, the boundary positions Xb1 of the first opening action restriction area α1 and Xb2 of the second opening action restriction area α2 can be arbitrarily changed. Alternatively, the structure could be such that the size of the opening action restriction area α set within the movement range 4X of the sliding door 4 is equal whether the opening action restriction area α is set during the sliding door 4's operation or during non-opening operations.

[0095] In the above embodiments, the operating switch 56 can be arbitrarily configured to be located on the leading side of the door opening 3 in the opening direction of the sliding door 4. For example, it can be a button type or a slider type. Furthermore, it can also be a structure using a touch sensor. And, for example, it can also be a non-contact type switch such as an electrostatic capacitive type.

[0096] In the above embodiment, braking control of the sliding door 4, located within the opening restriction region α, is performed by braking control of the electric motor 30, which serves as the drive source for the PSD actuator 31. However, this is not a limitation; for example, braking force can be generated by connecting an electromagnetic clutch or by utilizing a mechanical structure such as a structure with reverse input resistance characteristics applied to the reduction mechanism of the PSD actuator 31. Furthermore, the structure of the electric motor 30, which serves as the drive source, can be arbitrarily changed, for example, it can be a brushed DC motor.

[0097] Furthermore, the magnitude of the braking force applied to the sliding door 4 within the opening restriction zone α by the execution of braking control can be arbitrarily set. For example, it can be a forced force that prevents the sliding door 4 from opening through manual operation by the occupant, or it can be a braking force that requires a large operating force from the occupant to open the sliding door 4. In addition, for example, in the case where the door handle 51 is provided on the sliding door 4 only for emergency use, in a structure where the opening drive control of the sliding door 4 is mainly executed by the PSDECU35 to open the sliding door 4, the braking force can be at the level of maintaining the sliding door 4 in a stopped position. It is also possible to have a structure in which the opening of the sliding door 4 within the opening restriction zone α is limited by the execution of position control instead of performing explicit braking control.

[0098] In the above embodiment, the sliding door 4, which opens and closes the door opening 3 located on the side 2s of the vehicle body 2, is used as the opening and closing body. The vehicle opening and closing body control device is specifically defined as a sliding door device 10 equipped with a PSDECU 35 that performs the opening and closing drive control of the sliding door 4 and a PSD actuator 31. Furthermore, on the side 2s of the vehicle body 2 where the door opening 3 is located, an operation switch 56 for the rear door 14 is provided at a position that leads the door opening 3 in the opening direction of the sliding door 4.

[0099] However, it is not limited to this; for example, it can also be applied to vehicle opening and closing control devices that target opening and closing mechanisms other than sliding doors, such as sunroof devices. Furthermore, the operating switch 56 provided in the opening direction of the opening and closing mechanism can also be an operating switch 56 other than the operating input section 55 of the rear door 14. Moreover, the vehicle-mounted device that starts operating by inputting an operation to the operating switch 56 does not necessarily have to be a device that drives a movable part such as the rear door 14.

[0100] PSDECU35 and 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 Circuit: ASIC) that executes at least a portion of various processes, or (3) a processing circuitry that includes a combination of these. The processor includes a CPU and memories such as RAM and ROM, which store program code or instructions configured to cause the CPU to execute processes. Memory, i.e., non-transitory computer-readable media, includes any usable medium that can be accessed by a general-purpose or special-purpose computer.
