Description

[Technical field]

[0001] The present invention relates to a control device for an opening / closing member for a vehicle. [Background technology]

[0002] Conventionally, there is a control device for a vehicle opening / closing body that is configured to prevent pinching in the opening / closing body by restricting the opening / closing operation of the opening / closing body provided in the vehicle. For example, Patent Document 1 discloses a configuration that suppresses the movement speed of the opening / closing body when the window provided in the opening / closing body is in an open state and the moving position of the opening / closing body is within a predetermined specific opening operation range. By adopting such a configuration, it is possible to prevent pinching between the window of the opening / closing body in the open state and the vehicle body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-57659 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a vehicle, regardless of whether or not there is a window, the opening / closing body may interfere with a person outside the vehicle when the opening / closing body moves. [Means for solving the problem]

[0005] A vehicle opening / closing body control device that solves the above problem comprises a movement position detection unit that detects the movement position of an opening / closing body provided in an opening of the vehicle body, a drive control unit that performs drive control of the opening / closing body by controlling the operation of a drive device, and an opening operation restriction area setting unit that sets an opening operation restriction area including the fully open position of the opening / closing body within the movement range of the opening / closing body based on detection of an operation input to an operation switch provided on the vehicle body in the opening direction of the opening / closing body relative to the opening, and when the opening operation restriction area is set, the drive control unit restricts the opening operation of the opening / closing body in the opening operation restriction area.

[0006] That is, when an operation switch located in the opening direction of the opening / closing body from the opening where the opening / closing body is provided is operated, there is a possibility that the user operating this operation switch will enter the movement trajectory of the opening / closing body. However, according to the above configuration, in such a case, an opening operation restriction area including the fully open position is set, and the opening operation of the opening / closing body within the opening operation restriction area is restricted. This makes it possible to suppress interference between the opening / closing body and the user operating the operation switch provided in the opening direction of the opening / closing body. In addition, it is possible to prevent the user operating the operation switch from feeling a psychological sense of pressure due to the opening / closing body approaching.

[0007] In the vehicle opening / closing body control device that solves the above problem, it is preferable that, when the opening operation regulated region is set, the drive control unit does not execute the opening drive control of the opening / closing body in the opening operation regulated region.

[0008] According to the above configuration, the opening operation of the opening / closing body that has moved into the opening operation restriction area due to the execution of the opening drive control can be restricted, and the opening operation of the opening / closing body located in the opening operation restriction area can be restricted from starting due to the execution of the opening drive control. This makes it possible to suppress interference between the user operating the opening / closing body and the opening / closing body.

[0009] In a vehicle opening / closing body control device that solves the above-mentioned problems, it is preferable that, when the opening operation restriction area is set, the drive control unit executes braking control to apply a braking force to the opening / closing body within the opening operation restriction area to restrict the opening operation of the opening / closing body.

[0010] According to the above configuration, the opening operation of the opening / closing body that has moved into the opening operation restriction area can be restricted, including by manual operation, and the start of the opening operation of the opening / closing body located within the opening operation restriction area can be restricted. This makes it possible to suppress interference between the opening / closing body and a user who operates the operation switch provided in the opening direction of the opening / closing body.

[0011] In the vehicle opening / closing body control device that solves the above problem, it is preferable that the opening operation restriction region setting unit maintains the set opening operation restriction region while an operation input to the operation switch is detected.

[0012] In other words, it is highly likely that the user operating the operation switch is within the movement path of the opening / closing body while the operation switch is being operated. Therefore, with the above configuration, it is possible to more effectively prevent interference between the opening / closing body and the user operating the operation switch provided in the opening direction of the opening / closing body.

[0013] In the vehicle opening / closing body control device that solves the above-mentioned problems, it is preferable that the opening operation restriction area setting unit maintains the set opening operation restriction area until the operation of the on-board device that started operating by operational input to the operating switch stops.

[0014] In other words, while the opening / closing body that has started to operate by operating the operation switch is opening or closing, it is estimated that there is a high possibility that the user operating the operation switch is within the movement trajectory of the opening / closing body. Therefore, with the above configuration, it is possible to more effectively suppress interference between the opening / closing body and the user operating the operation switch provided in the opening direction of the opening / closing body.

[0015] In a vehicle opening / closing body control device that solves the above-mentioned problems, it is preferable that the opening operation restriction area setting unit maintains the set opening operation restriction area during the opening operation even if the conditions for maintaining the set opening operation restriction area are eliminated during the opening operation of the opening / closing body.

[0016] According to the above-mentioned configuration, if an operation input to the operation switch is detected even once, the opening operation restriction area set in the movement range of the opening / closing body is not released during the opening operation of the opening / closing body, and this makes it possible to more effectively prevent interference between the opening / closing body and a user who operates the operation switch provided in the opening direction of the opening / closing body.

[0017] In a vehicle opening / closing body control device that solves the above problem, when the opening operation restriction area setting unit sets the opening operation restriction area during the opening operation of the opening / closing body, it is preferable that it sets a second opening operation restriction area that is narrower than the first opening operation restriction area set as the opening operation restriction area when the opening / closing body is not performing the opening operation.

[0018] According to the above configuration, for example, even if the operation switch is operated immediately after the opening / closing body starts its opening operation, the opening operation of the opening / closing body continues to the extent that interference between the user who operated the operation switch and the opening / closing body can be suppressed. This makes it possible to avoid the occurrence of a situation in which the opening / closing body suddenly stops immediately after starting its opening operation, thereby ensuring a high quality feel.

[0019] A vehicle opening / closing body control device that solves the above problem includes a pinch detection unit that detects pinching that occurs in the opening / closing body, and when the pinch is detected, the drive control unit executes a reversal drive control that reverses the drive direction of the opening / closing body, and when the reversal drive control is executed, it is preferable that the opening / closing body is driven in the opening direction even in the opening operation restriction area.

[0020] According to the above-described configuration, when pinching of the opening / closing body is detected, priority is given to eliminating the pinching by executing the reverse drive control, thereby making it possible to ensure a high level of safety.

[0021] In a vehicle opening / closing body control device that solves the above problem, it is preferable that the opening / closing body is a sliding door provided on the side of the vehicle body, and the operation switch is an operation input unit for a tailgate provided at the rear end of the vehicle body.

[0022] According to the above-described configuration, interference between the sliding door and a user operating the back door operation switch provided on the opening side of the sliding door can be suppressed. Effect of the Invention

[0023] According to the present invention, it is possible to suppress interference of the opening / closing body with people outside the vehicle. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, an embodiment of a control device for an opening / closing member for a vehicle will be described with reference to the drawings. As shown in Fig. 1, a vehicle 1 of this embodiment is provided with a sliding door 4 that opens and closes a door opening 3 provided on a side surface 2s of a vehicle body 2. Specifically, the vehicle 1 is provided with a plurality of guide rails 5a-5c extending in the front-rear direction (left-right direction in Fig. 1) and a plurality of guide roller units 6a-6c connected to each of these guide rails 5. The sliding door 4 of this embodiment is supported on the side surface 2s of the vehicle body 2 via each of these guide rails 5 and each of the guide roller units 6.

[0026] Furthermore, each of the guide rails 5 and each of the guide roller units 6 can be displaced in a relative manner such that a connection position of each of the guide roller units 6 with respect to each of the guide rails 5 can be displaced along the extension direction of each of the guide rails 5. In the vehicle 1 of this embodiment, this provides a sliding door device 10 that enables the sliding door 4 provided in the door opening 3 to be opened and closed.

[0027] That is, in the sliding door device 10 of this embodiment, the sliding door 4 moves to the front side of the vehicle (left side in FIG. 1) to be in a fully closed state that blocks the door opening 3. The sliding door 4 is configured to move to the rear side of the vehicle (right side in FIG. 1) to be in an open state that allows passengers of the vehicle 1 to get on and off through the door opening 3.

[0028] The vehicle 1 of this embodiment also includes a door opening 13 that opens rearward and is provided at the rear end 2r of the vehicle body 2. The door opening 13 is provided with a so-called flip-up back door 14.

[0029] That is, the back door 14 opens upward with the upper end of the door opening 13 as a pivot point. A pair of support devices 15 having an axis shape configured to be freely expandable and contractible and having axial ends rotatably connected to the vehicle body 2 side and the back door 14 side are provided at both widthwise ends of the door opening 13. In the vehicle 1 of this embodiment, a back door device 20 is formed that opens and closes the door opening 13 configured as a so-called rear hatch based on the operation of the support devices 15.

[0030] The vehicle 1 of this embodiment is also provided with a PSD actuator 31 that drives the sliding door 4 to open and close using a motor 30 as a drive source, and a PSDECU 35 that controls the operation of the PSD actuator 31. The vehicle 1 is also provided with a PBD actuator 41 that drives the back door 14 to open and close using a motor 40 as a drive source, and a PBDECU 45 that controls the operation of the PBD actuator 41. Thus, in the vehicle 1 of this embodiment, the sliding door device 10 and the back door device 20 are configured as a so-called power sliding door and power back door that are opened and closed by motor drive, respectively.

[0031] More specifically, in the vehicle 1 of this embodiment, a pulse signal Sp1 synchronized with the operation of the PSD actuator 31 is input to the PSDECU 35. The PSDECU 35 of this embodiment counts the pulse signal Sp1 to detect the movement position Xsd of the sliding door 4 that opens and closes based on the driving force of the PSD actuator 31.

[0032] Similarly, a pulse signal Sp2 synchronized with the operation of the PBD actuator 41 is input to the PBDECU 45. The PBDECU 45 of this embodiment is configured to count the pulse signal Sp2 to detect the movement position Xbd of the back door 14 that opens and closes based on the driving force of the PBD actuator 41.

[0033] The movement position Xsd of the sliding door 4 is represented, for example, by its fully closed position or a pulse count value based on the fully closed position. Similarly, the movement position Xbd of the back door 14 is represented, for example, by its fully closed position or a pulse count value based on the fully closed position.

[0034] Further, the PSDECU 35 of this embodiment receives an operation input signal Scr1 for an operation input unit 53 provided on a door handle 51 of the sliding door 4, inside the vehicle compartment, or on a portable device 52 held by a user of the vehicle 1. Then, the PSDECU 35 controls the operation of the PSD actuator 31 based on an opening / closing operation request for the sliding door 4 indicated in the operation input signal Scr1 and the detected movement position Xsd, i.e., executes opening / closing drive control of the sliding door 4.

[0035] Similarly, an operation input signal Scr2 for an operation input unit 55 provided on the back door 14, the vehicle body 2, the portable device 52, etc. is input to the PSDECU 35. Specifically, the vehicle 1 of this embodiment is equipped with an operation switch 56 provided on the side surface 2s of the vehicle body 2 in the vicinity of the rear end portion 2r where the back door 14 is provided, as the operation input unit 55 for the back door 14. Then, the PBDECU 45 of this embodiment controls the operation of the PBD actuator 41 based on the opening / closing operation request of the back door 14 indicated in the operation input signal Scr2 and the detected movement position Xbd, that is, executes opening / closing drive control of the back door 14.

[0036] 2, when the PSDECU 35 and the PBDECU 45 detect an opening / closing operation request (step 101: YES), they specify the drive directions of the sliding door 4 and the back door 14 that are the targets of the opening / closing drive (step 102). Then, the PSDECU 35 and the PBDECU 45 each execute the opening / closing drive control in the specified drive direction (step 103).

[0037] In the vehicle 1 of this embodiment, the PSDECU 35 holds the opening / closing operation request detected in step 101 and the drive direction specified in step 102 during the execution of the opening / closing drive control. As a result, if a new operation input signal Scr1 is not detected, the slide door 4 driven by the PSD actuator 31 moves to the fully closed position or the fully open position by the drive control executed by the PSDECU 35.

[0038] Similarly, the PBDECU 45 also holds the opening / closing operation request detected in the above step 101 and the drive direction specified in the above step 102 during the execution of the opening / closing drive control. As a result, in the vehicle 1 of this embodiment, when a new operation input signal Scr2 is not detected, the back door 14 driven by the PBD actuator 41 moves to the fully closed position or the fully open position by the drive control executed by the PBDECU 45.

[0039] In the vehicle 1 of this embodiment, the sliding door 4 can be manually opened and closed by using the door handle 51 as a gripping part. Similarly, the back door 14 can also be manually opened and closed.

[0040] In the vehicle 1 of this embodiment, a pinch detection signal Scd1 indicating that pinching has occurred in the sliding door 4 that is being opened or closed by execution of the drive control or manually, that is, in the sliding door 4 in operation, is input to the PSDECU 35. Note that, for example, an output signal of a touch sensor (not shown) provided on a front edge 4f of the sliding door 4 is used as the pinch detection signal Scd1 of the sliding door 4. When pinching is detected by this, a reverse drive control of the sliding door 4 is executed.

[0041] Similarly, a pinch detection signal Scd2 indicating that pinching has occurred in the operating back door 14 is input to the PBDECU 45. Note that the pinch detection signal Scd2 for the back door 14 may be, for example, an output signal from a touch sensor (not shown) provided on the back door 14. When pinching is detected, a reverse drive control for the back door 14 is executed.

[0042] 3, when the PSDECU35 and the PBDECU45 detect entrapment (step 201: YES), they each stop the drive control of the sliding door 4 and the back door 14 that are the targets of the opening and closing drive (step 202). Then, in the stopped drive control, the PSDECU35 and the PBDECU45 each execute a drive in the opposite direction to the drive direction indicated in the opening and closing operation request, that is, a reverse drive control that reverses the direction of the drive request (step 203).

[0043] (Sliding door operation restriction control when back door switch is operated) Next, a slide door operation restriction control when the back door switch mounted on the vehicle 1 of this embodiment is operated will be described.

[0044] 4, in the vehicle 1 of this embodiment, an operation switch 56 for the back door 14 provided on a side surface 2s of the vehicle body 2 is disposed near the terminal 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 at a position in the opening direction of the sliding door 4 rather than the door opening 3 that is opened and closed by the sliding door 4. This creates the possibility that a user 60 outside the vehicle who intends to open or close the back door 14 by operating the operation switch 56 may enter within the movement trajectory Tsd of the sliding door 4.

[0045] In consideration of this, in the vehicle 1 of this embodiment, as shown in Figures 5 and 6, an opening operation 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 based on the detection of an operation input to the operation switch 56. In other words, when the operation switch 56 of the back door 14 is operated, it is estimated that there is a high possibility that the user 60 operating the operation switch 56 has entered the movement trajectory Tsd of the sliding door 4. In the opening operation restriction area α, the PSDECU 35 does not execute the opening drive control of the sliding door 4, thereby suppressing interference between the user 60 outside the vehicle operating the operation switch 56 of the back door 14 and the sliding door 4.

[0046] That is, the opening operation restriction area α is set in such a manner that it divides the movement range 4X of the sliding door 4 from the fully closed position Xc to the fully open position Xo in half. When the opening operation restriction area α is set, the PSDECU 35 applies a braking force to the sliding door 4 within the opening operation restriction area α to execute braking control to restrict the opening operation.

[0047] Specifically, in the vehicle 1 of this embodiment, a brushless motor is used for the motor 30 of the PSD actuator 31. The braking control executed when the above-mentioned opening operation restriction region α is set is performed by brake control of the motor 30, for example, energization control in which the energization phase of the motor coil is fixed, which is called "single-phase energization" or "fixed-phase energization", or regenerative brake control, etc.

[0048] Furthermore, when the opening operation restriction region α is set, the opening drive control of the slide door 4 by the PSDECU 35 is executed only in the opening operation permission region β which is closer to the fully closed position Xc than the opening operation restriction region α.

[0049] That is, when the movement position Xsd of the sliding door 4 is within the opening operation restriction region α, the PSDECU 35 does not start the opening drive control. Also, when the sliding door 4, which has moved in the opening direction through the opening operation permission region β by executing the opening drive control, enters the opening operation restriction region α, the PSDECU 35 stops the opening drive control. As a result, the vehicle 1 of this embodiment is configured such that the sliding door 4 stopped within the opening operation restriction region α does not move in the opening direction toward the fully open position Xo, that is, does not perform the opening operation.

[0050] In detail, the PSDECU 35 of this embodiment maintains the opening operation restriction area α set in the movement range 4X of the sliding door 4 while an operation input to the operation switch 56 of the back door 14 is detected. The PSDECU 35 also maintains the opening operation restriction area α until the opening / closing operation of the back door 14 via the operation input to the operation switch 56 is stopped, that is, the opening / closing drive control by the PBDECU 45 is terminated. Furthermore, even if the condition for maintaining the opening operation restriction area α is eliminated, the PSDECU 35 maintains the set opening operation restriction area α during the opening operation of the sliding door 4. In other words, if an operation input to the operation switch 56 is detected even once, the opening operation restriction area α set in the movement range 4X is not released during the opening operation of the sliding door 4. In this way, the vehicle 1 of this embodiment is configured to more effectively suppress interference between the user 60 outside the vehicle who operates the operation switch 56 of the back door 14 and the sliding door 4.

[0051] Furthermore, when setting the opening operation restriction area α, the PSDECU 35 of this embodiment changes the size of the opening operation restriction area α depending on whether the sliding door 4 is in an opening operation. That is, the "opening operation" in this case includes the movement of the sliding door 4 in the opening direction by the opening drive control of the PSDECU 35 and the movement of the sliding door 4 in the opening direction by manual operation. When setting the opening operation restriction area α during the opening operation of the sliding door 4, the PSDECU 35 of this embodiment sets the opening operation restriction area α narrower than when setting the opening operation restriction area α in a state in which the sliding door 4 is not in an opening operation, i.e., during a non-opening operation.

[0052] In other words, the second opening operation regulated area α2 set during the opening operation has a boundary position Xb with the opening operation permitted area β at a position closer to the fully open position Xo than the first opening operation regulated area α1 set during the non-opening operation of the sliding door 4. This allows the sliding door 4 to be opened to a position closer to the fully open position Xo when the opening operation regulated area α is set after the opening operation is started than when the opening operation regulated area α is set at the time of starting the opening operation.

[0053] Specifically, in the vehicle 1 of this embodiment, the first opening operation restriction area α1 is set so that when the sliding door 4 stops at the boundary position Xb1 based on the fully closed position Xc, an opening amount sufficient for passengers to get in and out through the door opening 3 is ensured. The second opening operation restriction area α2 is set so that, even when the sliding door 4 stops at the boundary position Xb2 based on the fully open position Xo, interference with the user 60 operating the operation switch 56 that has entered within the movement trajectory Tsd of the sliding door 4 can be avoided.

[0054] 1, in the vehicle 1 of this embodiment, the PBDECU 45 transmits to the PSDECU 35 an opening operation restriction signal Sld for the sliding door 4 based on detection of an operation input to the operation switch 56 of the back door 14. The opening operation restriction signal Sld is transmitted and received using an in-vehicle network (not shown). The PSDECU 35 of this embodiment sets an opening operation restriction region α for the movement range 4X of the sliding door 4 based on the opening operation restriction signal Sld.

[0055] 7, when the PBDECU 45 detects an operation input to the operation switch 56 of the back door 14 (step 301: YES), the PBDECU 45 transmits an opening operation restriction signal Sld of the sliding door 4 to the PSDECU 35 (step 302). Furthermore, the PBDECU 45 of this embodiment executes the above-mentioned steps 301 and 302 and the processes of steps 303 to 305 shown below at a predetermined calculation cycle. Thus, in the vehicle 1 of this embodiment, the PBDECU 45 is configured to continuously transmit the opening operation restriction signal Sld to the PSDECU 35 while the user 60 outside the vehicle is operating the operation switch 56 of the back door 14.

[0056] In addition, when the PBDECU 45 does not detect an operation input to the operation switch 56 of the back door 14 in the above step 301 (step 301: NO), the PBDECU 45 judges whether the back door 14 is in operation (step 303). Furthermore, when the back door 14 is in operation (step 303: YES), the PBDECU 45 judges whether the operation of the back door 14 is due to a drive control started by the detection of an operation input to the operation switch 56 (step 304). Then, the PBDECU 45 of this embodiment executes the process of the above step 302 even when the operation of the back door 14 is due to a drive control started by the detection of an operation input to the operation switch 56 (step 304: YES). In other words, even after the detection of the operation input to the operation switch 56 is discontinued, the PBDECU 45 is configured to continue transmitting the opening operation restriction signal Sld to the PSDECU 35 until the drive control of the back door 14 started by the detection of the operation input is completed.

[0057] In this embodiment, the PBDECU 45 does not transmit the opening operation restriction signal Sld (step 305) when the back door 14 is not in operation (step 303: NO) or when no operation input to the operation switch 56 is detected (step 301: NO). Even when the back door 14 is in operation triggered by something other than the detection of an operation input to the operation switch 56 (step 304: NO), the PBDECU 45 does not transmit the opening operation restriction signal Sld to the PSDECU 35 if no operation input to the operation switch 56 is detected.

[0058] 8, when the PSDECU35 of this embodiment receives the opening operation restriction signal Sld (step 401: YES), it judges whether the opening operation restriction area α has been set, i.e., is being set, for the moving range 4X of the sliding door 4 (step 402). If the opening operation restriction area α has already been set (step 402: YES), the currently set opening operation restriction area α is maintained (step 403), and if it has not been set (step 402: NO), it executes a setting judgment of the opening operation restriction area α (step 404).

[0059] Specifically, as shown in Fig. 9, in determining whether or not the opening operation restriction region α is set, the PSDECU35 of this embodiment determines whether or not the sliding door 4 is in an opening operation (step 501). If the sliding door 4 is not in an opening operation, i.e., is not in an opening operation (step 501: NO), the PSDECU35 sets the first opening operation restriction region α1 as the opening operation restriction region α (step 502, see Fig. 5). If the sliding door 4 is in an opening operation (step 501: YES), the PSDECU35 sets the second opening operation restriction region α2 as the opening operation restriction region α (step 503, see Fig. 6).

[0060] 8, even if the PSDECU35 of this embodiment does not receive the opening operation regulation signal Sld (step 401: NO), it determines whether the opening operation regulation region α has already been set (step 405). If the opening operation regulation region α has already been set (step 402: YES), the PSDECU35 executes a release determination for the set opening operation regulation region α.

[0061] 10, in determining whether or not to release the opening operation restriction region α, the PSDECU 35 of this embodiment also determines whether the sliding door 4 is in an opening operation (step 601). If the sliding door 4 is not in an opening operation, that is, if the sliding door 4 is not in an opening operation (step 601: NO), the PSDECU 35 releases the opening operation restriction region α set for the movement range 4X of the sliding door 4 (step 602). If the sliding door 4 is in an opening operation (step 601: YES), the PSDECU 35 maintains the setting of the opening operation restriction region α for the movement range 4X of the sliding door 4 (step 603).

[0062] 11, when an opening operation restriction area α is set in the movement range 4X of the sliding door 4 (step 701: YES), the PSDECU 35 of this embodiment judges whether the sliding door 4 is located within the opening operation restriction area α (step 702). Furthermore, when the sliding door 4 is located within the opening operation restriction area α (step 702: YES), the PSDECU 35 judges the movement direction of the sliding door 4 (step 703). Then, when the sliding door 4 located within the opening operation restriction area α is moving in the opening direction or is about to start moving in the opening direction (step 702: YES), the PSDECU 35 executes braking control of the sliding door 4 to restrict the opening operation (step 704).

[0063] Furthermore, when the PSDECU 35 of this embodiment detects pinching of the sliding door 4 as described above, it executes reverse drive control of the sliding door 4 (see FIG. 3). When the reverse drive control is executed, the sliding door 4 is driven in the opening direction even if the sliding door 4 is located within the opening operation restriction region α.

[0064] 12, when there is a request to open the sliding door 4 (step 801: YES), the PSDECU 35 of this embodiment judges whether the sliding door 4 is located in the opening operation restricted area α (step 802). If the sliding door 4 is not located in the opening operation restricted area α (step 802: NO), that is, if the sliding door 4 is located in the opening operation permitted area β on the fully closed position Xc side, the PSDECU 35 executes the opening drive control of the sliding door 4 based on the opening drive request (step 803).

[0065] That is, in this case, the PSDECU 35 of this embodiment does not execute the braking control of the sliding door 4 due to the setting of the opening operation restriction region α. ​​Then, the PSDECU 35 starts a new opening drive control of the sliding door 4 based on the opening drive request of the above step 801, and continues the opening drive control that is being executed.

[0066] Furthermore, in the above step 802, if the sliding door 4 is located in the opening operation restriction region α (step 802: YES), the PSDECU 35 subsequently determines whether the open drive request in the above step 801 is due to the reverse drive control (step 804). Furthermore, even if the open drive request is due to the reverse drive control (step 804: YES), the PSDECU 35 executes the above step 803 to drive the sliding door 4 in the opening direction. Then, if the open drive request is not due to the reverse drive control (step 804: NO), the PSDECU 35 rejects the open drive request in the above step 801 (step 805).

[0067] That is, when the open drive request is based on the operation input signal Scr1, the PSDECU 35 of this embodiment executes braking control to regulate the opening operation of the sliding door 4 in the open operation regulation region α. ​​Furthermore, the PSDECU 35 does not execute the open drive control of the sliding door 4 in the open operation regulation region α. ​​As a result, in the vehicle 1 of this embodiment, a new open drive control is not started for the sliding door 4 located in the open operation regulation region α, and the open drive control being executed is stopped.

[0068] Next, the operation of this embodiment will be described. That is, while the user 60 outside the vehicle is operating the operation switch 56 of the back door 14, the PBDECU 45 continues to transmit the opening operation restriction signal Sld to the PSDECU 35. Furthermore, while the PSDECU 35 is receiving this opening operation restriction signal Sld, the opening operation restriction area α set in the movement range 4X of the sliding door 4 is maintained by the reception of this opening operation restriction signal Sld. Therefore, while the user 60 outside the vehicle is operating the operation switch 56 of the back door 14, the opening operation of the sliding door 4 in the opening operation restriction area α is restricted.

[0069] Furthermore, until the drive control of the back door 14 that was started upon detection of the operation input to the operation switch 56 is completed, the opening operation restriction signal Sld is continuously transmitted from the PBDECU 45 to the PSDECU 35. As a result, the opening operation of the sliding door 4 in the opening operation restriction region α is restricted until the drive control of the back door 14 based on the operation input to the operation switch 56 is completed.

[0070] Furthermore, even if the opening operation restriction signal Sld by the PBDECU45 is interrupted, the opening operation restriction region α set in the movement range 4X of the sliding door 4 is maintained during the opening operation of the sliding door 4. In other words, if the PSDECU35 receives the opening operation restriction signal Sld transmitted by the PBDECU45 even once, the set opening operation restriction region α is not released during the opening operation of the sliding door 4. Therefore, for the sliding door 4 that is in the opening operation of the opening operation permission region β, the opening drive control is stopped by entering the opening operation restriction region α, and the braking control is executed. Then, after the opening operation of the sliding door 4 is stopped, the opening operation restriction region α set in the movement range 4X of the sliding door 4 is released based on the interruption of the opening operation restriction signal Sld.

[0071] Next, the effects of this embodiment will be described. (1) The sliding door device 10 as a vehicle opening / closing body control device includes a PSD actuator 31 as a drive device that drives the sliding door 4 as an opening / closing body to open and close. The sliding door device 10 also includes a PSDECU 35 having a function as a drive control unit 70a that executes drive control of the sliding door 4 by controlling the operation of the PSD actuator 31. The PSDECU 35 also has a function as a movement position detection unit 70b that detects a movement position Xsd of the sliding door 4. An operation switch 56 for the back door 14 is provided on a side surface 2s of the vehicle body 2 in which a door opening 3 as an opening that is opened and closed by the sliding door 4 is provided, at a position in the opening direction of the sliding door 4 from the door opening 3. The PSDECU 35 also has a function as an opening operation restriction area setting unit 70c that sets an opening operation restriction area α including a full open position Xo of the sliding door 4 in the movement range 4X of the sliding door 4 based on detection of an operation input to the operation switch 56. When the opening operation restriction region α is set, the PSDECU 35 restricts the opening operation of the slide door 4 in the opening operation restriction region α.

[0072] That is, when the operation switch 56 of the back door 14 located in the opening direction of the sliding door 4 from the door opening 3 where the sliding door 4 is provided is operated, the user 60 operating the operation switch 56 may enter the movement trajectory Tsd of the sliding door 4. However, according to the above configuration, in such a case, the opening operation restriction area α including the full open position Xo is set, and the opening operation of the sliding door 4 within the opening operation restriction area α is restricted. This makes it possible to suppress interference between the sliding door 4 and the user 60 outside the vehicle who operates the operation switch 56 provided in the opening direction of the sliding door 4. In addition, it is possible to prevent the user 60 operating the operation switch 56 of the back door 14 from feeling a psychological sense of pressure due to the approach of the sliding door 4.

[0073] (2) When the opening operation restriction region α is set, the PSDECU 35 does not execute the opening drive control of the slide door 4 in the opening operation restriction region α. According to the above configuration, the opening operation of the sliding door 4 that has moved into the opening operation restriction region α due to the execution of the opening drive control is restricted, and the start of the opening operation of the sliding door 4 that is located within the opening operation restriction region α due to the execution of the opening drive control can be restricted. This makes it possible to suppress interference between the user 60 operating the operation switch 56 and the sliding door 4.

[0074] (3) When the opening operation restriction region α is set, the PSDECU 35 applies a braking force to the sliding door 4 within the opening operation restriction region α, thereby executing braking control for restricting the opening operation of the sliding door 4.

[0075] According to the above configuration, the opening operation of the sliding door 4 that has moved into the opening operation restriction area α can be restricted, including the case where the opening operation is caused by the manual operation of the occupant, and the start of the opening operation of the sliding door 4 that is located within the opening operation restriction area α can be restricted. This makes it possible to suppress interference between the sliding door 4 and the user 60 who operates the operation switch 56 provided in the opening direction of the sliding door 4.

[0076] (4) The PSDECU 35 maintains the opening operation restriction area α set in the movement range 4X of the sliding door 4 while an operation input to the operation switch 56 is being detected. That is, while the operation switch 56 is being operated, it is estimated that there is a high possibility that the user 60 operating this operation switch 56 is within the movement trajectory Tsd of the sliding door 4. Therefore, according to the above-mentioned configuration, it is possible to more effectively suppress interference between the sliding door 4 and the user 60 operating the operation switch 56 provided in the opening direction of the sliding door 4.

[0077] (5) The PSDECU 35 maintains the opening operation restriction region α set in the movement range 4X of the sliding door 4 until the opening / closing operation of the back door 14, which is an in-vehicle device that has started to operate in response to an operation input to the operation switch 56, stops.

[0078] That is, while the back door 14, whose operation has been started by operating the operation switch 56, is opening and closing, it is estimated that there is a high possibility that the user 60 operating the operation switch 56 is within the movement trajectory Tsd of the sliding door 4. Therefore, according to the above-mentioned configuration, it is possible to more effectively suppress interference between the sliding door 4 and the user 60 operating the operation switch 56 provided in the opening direction of the sliding door 4.

[0079] (6) Even if the conditions for maintaining the opening operation restriction region α described in (4) and (5) above are eliminated while the PSDECU35 is executing the opening drive control of the sliding door 4, the PSDECU35 maintains the opening operation restriction region α set in the movement range 4X of the sliding door 4 while the opening drive control is being executed.

[0080] According to the above configuration, if an operation input to the operation switch 56 is detected even once, the opening operation restriction area α set in the movement range 4X is not released during the opening operation of the sliding door 4. In addition, the opening operation of the sliding door 4 moving in the opening operation permitted area β in the opening direction is restricted by the sliding door 4 entering the opening operation restriction area α. Then, after the opening operation of the sliding door 4 stops, if an operation input to the operation switch 56 is not detected, the opening operation restriction area α set in the movement range 4X is released.

[0081] As a result, the sliding door 4 can be opened in a state where the possibility that the user 60 operating the operation switch 56 has entered within the movement trajectory Tsd of the sliding door 4 is reduced. This makes it possible to more effectively suppress interference between the sliding door 4 and the user 60 operating the operation switch 56 provided in the opening direction of the sliding door 4.

[0082] (7) When PSDECU35 sets the opening operation restriction area α during the opening operation of the sliding door 4, it sets a second opening operation restriction area α2 that is narrower than the first opening operation restriction area α1 that is set as the opening operation restriction area α when the sliding door 4 is not opening.

[0083] According to the above configuration, for example, even if the operation switch 56 is operated immediately after the sliding door 4 starts its opening operation, the opening operation of the sliding door 4 is continued 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 who entered the movement locus Tsd and the sliding door 4 is likely to occur in the opening operation restriction area α, the operation switch 56 of the back door 14 is unlikely to be operated while the sliding door 4 is opening in the opening operation restriction area α. Therefore, according to the above configuration, even if the operation switch 56 is operated immediately after the opening operation starts, the opening operation of the sliding door 4 can be continued at least for an amount equivalent to the difference between the first opening operation restriction area α1 and the second opening operation restriction area α2 while suppressing interference. This makes it possible to avoid the occurrence of a situation in which the sliding door 4 suddenly stops immediately after the opening operation starts, and ensure a high quality feel.

[0084] (8) The PSDECU 35 has a function as an entrapment detection unit 70d that detects entrapment occurring in the sliding door 4. Furthermore, when the PSDECU 35 detects entrapment in the sliding door 4, it executes a reversal drive control that reverses the drive direction of the sliding door 4. Furthermore, when the PSDECU 35 executes the reversal drive control, it drives the sliding door 4 in the opening direction even in the opening operation restriction region α.

[0085] According to the above-mentioned configuration, when pinching in the sliding door 4 is detected, priority is given to eliminating the pinching by executing the reverse drive control, and thus a high level of safety can be ensured.

[0086] The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0087] In the above embodiment, the opening operation restriction area α is set in the movement range 4X of the sliding door 4 by the PSDECU35 receiving the opening operation restriction signal Sld transmitted by the PBDECU45. However, this is not limited thereto, and a detection signal of an operation input to the operation switch 56 of the back door 14 and a drive state signal of the back door 14 by the PBDECU45 are input to the PSDECU35. Then, in response to this, the PSDECU35 may be configured to determine the possibility of the user 60 entering the movement trajectory Tsd of the sliding door 4 corresponding to the transmission of the opening operation restriction signal Sld by the PBDECU45.

[0088] That is, the detection of the operation input to the operation switch 56 may be executed by the PSDECU 35. The determination of the necessity of setting the opening operation restriction region α based on the detection of the operation input and the determination of maintaining the set opening operation restriction region α may also be performed independently by the PSDECU 35.

[0089] The conditions for maintaining the opening operation restriction region α set in the movement range 4X of the sliding door 4 may be changed arbitrarily. In the above embodiment, the set positions of the boundary position Xb1 of the first opening operation restriction area α1 and the boundary position Xb2 of the second opening operation restriction area α2 may be changed arbitrarily. The size of the opening operation restriction area α set in the movement range 4X of the sliding door 4 may be equal when the opening operation restriction area α is set during operation of the sliding door 4 and when the opening operation restriction area α is set during non-open operation.

[0090] In the above embodiment, the configuration of the operation switch 56 provided on the vehicle body 2 in the opening direction of the sliding door 4 from the door opening 3 in which the sliding door 4 is provided may be set arbitrarily. For example, it may be a button type or a slide type. Furthermore, it may be configured to use a touch sensor. And, for example, it may be a non-contact type switch such as a capacitance type switch.

[0091] In the above embodiment, the brake control of the motor 30 which is the drive source of the PSD actuator 31 is performed to control the brake of the sliding door 4 located within the opening operation restriction region α. ​​However, this is not limited to this, and the braking force may be generated by a mechanical configuration, such as a configuration that utilizes a reverse input resistance characteristic imparted to the speed reduction mechanism of the PSD actuator 31 by connecting an electromagnetic clutch. The configuration of the motor 30 which is the drive source may also be changed arbitrarily, for example, to a brushed DC motor, etc.

[0092] The magnitude of the braking force applied to the sliding door 4 in the opening operation restriction region α by executing the braking control may be set arbitrarily. For example, a strong braking force may be applied so that the sliding door 4 will not be opened even by the manual operation of the occupant, or a braking force may be applied so that the occupant who manually opens the sliding door 4 needs to exert a large operating force. In addition, in a configuration in which the sliding door 4 is opened by the opening drive control mainly executed by the PSDECU 35, such as when only the emergency door handle 51 is provided on the sliding door 4, the braking force may be sufficient to hold the sliding door 4 at a stopped position. And, the opening operation of the sliding door 4 in the opening operation restriction region α may be restricted by executing a position control rather than an explicit braking control.

[0093] In the above embodiment, the sliding door device 10 is embodied as including a PSDECU 35 and a PSD actuator 31 that executes opening / closing drive control of the sliding door 4, which is an opening / closing body that opens and closes the door opening 3 provided on the side surface 2s of the vehicle body 2. An operation switch 56 for a back door 14 is provided at a position in the opening direction of the sliding door 4 relative to the door opening 3 on the side surface 2s of the vehicle body 2 where the door opening 3 is provided.

[0094] However, the present invention is not limited to this, and may be applied to a vehicle opening / closing body control device for an opening / closing body other than a sliding door, such as a sunroof device. Furthermore, the operation switch 56 provided on the opening side of the opening / closing body may be an operation switch 56 other than the operation input unit 55 of the back door 14. The in-vehicle device that starts to operate in response to an operation input to the operation switch 56 does not necessarily have to drive a movable member such as the back door 14.
