Description

TECHNICAL FIELD

[0001] The present disclosure relates to a door opening and closing device for a vehicle. BACKGROUND

[0002] Conventionally, as a vehicle of a van type, a vehicle shown in Patent Document 1 is known. In such a vehicle, an electric sliding door that opens and closes a stepwell formed in a side portion of the vehicle, and an electric rear door that opens and closes an opening portion formed in a rear portion of the vehicle are installed. The sliding door is moved in a front-rear direction of the vehicle by driving of an electric motor, thereby opening and closing the stepwell. The rear door is rotated up and down by driving of an electric motor with the aid of a door hinge provided in an upper portion of the opening portion, thereby opening and closing the opening portion. Also, the above-described rear door is generally provided with an opening and closing switch in a central portion of an outer surface of the rear door.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2009-108605 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, in the above-described rear door, since the user opens the rear door while standing in a position opposite to the rear door, it is necessary to retreat greatly in order to avoid the opened rear door after operating the switch. Therefore, there is a problem that the use convenience of the rear door is deteriorated, particularly in a case where the rear door is opened and closed in a limited space.

[0008] In order to solve this problem and make the use convenience of the rear door good, it is considered to arrange the opening and closing switch of the rear door in a rear end portion of a side portion of the vehicle. In this case, the user can operate the opening and closing switch of the rear door while standing beside the rear door, so it is not necessary to avoid the opened rear door. Therefore, the user can easily perform the opening and closing operation of the rear door even in a limited space.

[0009] However, in the above-described vehicle, if the sliding door is opened when the opening and closing switch of the rear door arranged in the rear end portion of the side portion of the vehicle is operated, the person who operates the switch sometimes does not notice the retreated sliding door only by the opening and closing operation of the rear door. Therefore, there is a problem that the retreated sliding door can contact the person who operates the opening and closing switch of the rear door.

[0010] Further, such a problem is not limited to the opening and closing operation of the rear door, but is generally common in the operation of an operation object other than the rear door.

[0011] SOLUTION TO THE PROBLEM

[0012] A door opening and closing device for a vehicle that addresses the above-described problems includes a door that moves between a fully closed position in which a step portion formed in a side portion of the vehicle is fully closed and a fully open position in which the step portion is fully opened, a drive portion that drives the door to open and close, and a control portion that controls the drive portion based on an input of an instruction signal to open and close the door. An operation portion that operates an operation object is provided at a position on the side portion of the vehicle that is rearward of the step portion. The control portion prohibits or restricts movement of the door to the fully open position based on driving of the drive portion when the operation portion is operated. BRIEF DESCRIPTION OF DRAWINGS

[0022] Hereinafter, an embodiment of a vehicle in which a door opening and closing device for a vehicle is installed will be described with reference to the drawings.

[0023] As Figure 1As shown, the vehicle 11 has multiple (six in this embodiment) seats 12 for passengers P to sit in. That is, inside the vehicle 11, the left and right pairs of seats 12 are arranged in three rows in the front-to-back direction X and in the width direction Y. The rightmost seat 12 in the front row is the driver's seat, and the leftmost seat 12 in the front row is the front passenger seat.

[0024] A left front door 13 and a right front door 14 are respectively located to the left of the passenger seat and to the right of the driver's seat in vehicle 11. Passenger hatches 15 are located on both sides of the front of vehicle 11 in the width direction Y. The left front door 13 and the right front door 14 open and close these passenger hatches 15. Both the left front door 13 and the right front door 14 are manually hinged doors.

[0025] In vehicle 11, a left PSD16 and a right PSD17, serving as examples of doors, are respectively provided on the left side of the left seat 12 in the second row and on the right side of the right seat 12 in the second row. In this specification, "PSD" refers to an electric sliding door as an electric sliding door.

[0026] Left PSD16 and right PSD17, as examples, constitute the left and right rear doors, respectively. Passenger / alight openings 18 are respectively provided on both sides of the rear of the vehicle 11 in the Y-direction of vehicle width. Left PSD16 and right PSD17 open and close these passenger / alight openings 18. Pillars 19 are respectively provided between the passenger / alight openings 15 on both sides of the front of the vehicle 11 and the passenger / alight openings 18 on both sides of the rear of the vehicle 11.

[0027] The vehicle 11 is equipped with a left PSD motor 20, which serves as an example of a drive unit. The left PSD 16 is in the fully closed position, with the left passenger / alighting port 18 completely closed, by the left PSD motor 20. Figure 1 The position shown by the solid line) and the fully open position, which is located further back than the fully closed position and fully opens the left-side passenger / alighting gate 18. Figure 1 The left PSD motor 20 is an electric motor capable of both forward and reverse rotation. A left-side magnetic sensor 42 (see reference) is built into the left PSD motor 20. Figure 4 The left magnetic sensor 42 can output a number of pulse signals proportional to the rotation of the left PSD motor 20. The left magnetic sensor 42 is constructed, for example, by a Hall IC.

[0028] The vehicle 11 is equipped with a right PSD motor 21, which serves as an example of a drive unit. The right PSD 17 is in the fully closed position, where the right passenger / alighting port 18 is completely closed, by the right PSD motor 21. Figure 1 The position shown by the solid line) and the fully open position, which is located further back than the fully closed position and fully opens the right-side passenger / alighting gate 18. Figure 1between the position indicated by the double-dotted line of the left PSD full-closed position (the position indicated by the solid line of the left PSD full-open position) and the position indicated by the double-dotted line of the left PSD full-open position (the position indicated by the solid line of the left PSD full-closed position). The right PSD motor 21 is an electric motor that can be rotated in both directions. A right magnetic sensor 43 (refer to Figure 4 ) is built in the right PSD motor 21. The right magnetic sensor 43 can output a pulse signal of a number proportional to the amount of rotation of the right PSD motor 21. The right magnetic sensor 43 is configured by, for example, a Hall IC.

[0029] A left PSD full-closed sensor 22 that detects that the left PSD 16 is in the full-closed position is provided in the vicinity of the left PSD 16 in the state of being in the full-closed position in the vehicle 11. A right PSD full-closed sensor 23 that detects that the right PSD 17 is in the full-closed position is provided in the vicinity of the right PSD 17 in the state of being in the full-closed position in the vehicle 11.

[0030] A left PSD operation switch 24 that operates the opening and closing of the left PSD 16 and a right PSD operation switch 25 that operates the opening and closing of the right PSD 17 are provided in the instrument panel (omitted from the drawing) in the interior of the vehicle 11 in front of the driver's seat. A PBD 26 that is an example of an operation target object is provided in the rear portion (rear end portion) in the vehicle 11. In this specification, it is assumed that "PBD" means an electrically driven back door that is an electrically driven back door. The PBD 26 opens and closes an opening portion 27 formed in the rear of the vehicle 11.

[0031] The PBD 26 is driven to open and close between the full-closed position (the position indicated by the solid line of the PBD full-closed position) of the opening portion 27 in which the opening portion 27 is fully closed and the full-open position (the position indicated by the double-dotted line of the PBD full-open position) in which the opening portion 27 is fully opened. Figure 1 Figure 1 The PBD motor 28 is an electric motor that can be rotated in both directions.

[0032] A rear magnetic sensor 47 (refer to Figure 4 ) is built in the PBD motor 28. The rear magnetic sensor 47 can output a pulse signal of a number proportional to the amount of rotation of the PBD motor 28. The rear magnetic sensor 47 is configured by, for example, a Hall IC. A PBD full-closed sensor 29 that detects that the PBD 26 is in the full-closed position is provided in the vicinity of the PBD 26 in the state of being in the full-closed position in the vehicle 11.

[0033] ​On both sides of the vehicle 11 in the width direction Y, at the rear end relative to the two passenger openings 18, there are two operating parts for opening and closing the PBD26: a left PBD operating switch 30 and a right PBD operating switch 31. In other words, portions of the left and right PBD operating switches 30 and 31 protrude outside the vehicle, allowing the PBD26 to be opened and closed regardless of which switch is operated from outside the vehicle.

[0034] The PBD26 has a hinge at its upper end, allowing it to rotate between the fully closed and fully open positions around the hinge. The PBD26 can be stopped at any position between the fully closed and fully open positions by operating the left PBD operating switch 30 or the right PBD operating switch 31.

[0035] like Figure 2 As shown, an upper sliding mechanism 32, a central sliding mechanism 33, and a lower sliding mechanism 34 are provided on the left side of the vehicle 11 in the vehicle width direction Y to guide the left PSD16 to slide between the fully open position and the fully closed position.

[0036] The upper sliding mechanism 32 includes an upper guide rail 35 and an upper guide roller 36. The upper guide rail 35 extends in the vehicle's longitudinal direction X, above the passenger / alighting opening 18 on the left side of the vehicle 11. The upper guide roller 36 is disposed on the upper part of the inner surface of the left PSD 16. The upper guide roller 36 is configured to move inside the upper guide rail 35. The upper sliding mechanism 32 guides the upper guide roller 36 by using the upper guide rail 35, thereby guiding the upper part of the left PSD 16 to slide in the vehicle's longitudinal direction X.

[0037] The central sliding mechanism 33 includes a central guide rail 37 and a central guide roller 38. The central guide rail 37 extends in the vehicle's longitudinal direction (X) at a position rearward of the passenger compartment 18 on the left side of the vehicle 11. The central guide roller 38 is located at the center of the inner surface of the left PSD 16 in the vertical direction. The central guide roller 38 is configured to move within the central guide rail 37. The central sliding mechanism 33 guides the central guide roller 38 by using the central guide rail 37, thereby guiding it to slide in the vehicle's longitudinal direction (X) at the center of the left PSD 16 in the vertical direction.

[0038] The lower slide mechanism 34 has a lower guide rail 39 and a lower guide roller 40. The lower guide rail 39 extends in the vehicle longitudinal direction X at a position lower than the door opening 18 in the left side surface of the vehicle 11. The lower guide roller 40 is provided to the inner surface lower portion of the left PSD 16. The lower guide roller 40 is arranged so as to move inside the lower guide rail 39. The lower slide mechanism 34 guides the lower guide roller 40 by using the lower guide rail 39, thereby guiding the lower portion of the left PSD 16 so as to slide in the vehicle longitudinal direction X.

[0039] As shown in Figure 1 and Figure 3 , a position at which the left PSD 16 opens a portion of the door opening 18 between the fully closed position and the fully open position is set as a reference position. The reference position is a position at which, when the left PSD 16 is at the reference position, the passenger P seated on the seat 12 in the second row in the vehicle 11 is not hindered from getting on and off the door opening 18 on the left side, and the left PSD 16 does not reliably come into contact with another passenger P who stands in front of the left PBD operation switch 30 and operates the left PBD operation switch 30.

[0040] As with the case of the left PSD 16 described above, the upper slide mechanism 32, the central slide mechanism 33, and the lower slide mechanism 34 for guiding the sliding movement of the right PSD 17 between the fully open position and the fully closed position are also provided to the right side portion in the vehicle width direction Y in the vehicle 11. Further, a position at which the right PSD 17 opens a portion of the door opening 18 between the fully closed position and the fully open position is set as a reference position.

[0041] The reference position is, as with the case of the left PSD 16 described above, a position at which, when the right PSD 17 is at the reference position, the passenger P seated on the seat 12 in the second row in the vehicle 11 is not hindered from getting on and off the door opening 18 on the right side, and the right PSD 17 does not reliably come into contact with another passenger P who stands in front of the right PBD operation switch 31 and operates the right PBD operation switch 31.

[0042] Next, the electrical configuration of the vehicle 11 will be described.

[0043] As shown in Figure 4 , the vehicle 11 has a control section 41 that centrally controls the entire vehicle 11. The control section 41 is configured by a computer, and has a CPU, a ROM, and a RAM. Various control programs and various information and the like are stored in the ROM. The various control programs include a program for the PSD opening drive processing shown in the flowchart of Figure 5 . The various information includes reference position information of the left PSD 16 and reference position information of the right PSD 17. Various data and the like that are the results of the operations and the processing results of the CPU are temporarily stored in the RAM.

[0044] The input-side interface of the control unit 41 (not shown) is electrically connected to PSD operation switches 24 and 25, PSD full-off sensors 22 and 23, PBD full-off sensors 29, PBD operation switches 30 and 31, and magnetic sensors 42 and 43, respectively. On the other hand, the output-side interface of the control unit 41 (not shown) is electrically connected to the left PSD motor 20, the right PSD motor 21, and the PBD motor 28 via motor drivers 44, 45, and 46, respectively.

[0045] The control unit 41 controls the driving of PSD motors 20 and 21 via motor drivers 44 and 45 based on the command signals sent from PSD operation switches 24 and 25 to open and close PSDs 16 and 17. The control unit 41 determines the position of PSDs 16 and 17 based on the pulse signals output from magnetic sensors 42 and 43 and the signals output from PSD full-close sensors 22 and 23.

[0046] The control unit 41 controls the drive of the PBD motor 28 via the motor driver 46 based on the command signal for opening or closing the PBD 26 sent from the left PBD operating switch 30 or the right PBD operating switch 31. The control unit 41 determines the position of the PBD 26 based on the pulse signal output from the rear magnetic sensor 47 and the signal output from the PBD fully closed sensor 29. Furthermore, in this embodiment, the PSDs 16 and 17, the PSD motors 20 and 21, and the control unit 41 constitute a vehicle door opening and closing device.

[0047] Next, based on Figure 5 The flowchart shown illustrates the PSD opening driver processing (PSD opening driver processing) executed by the control unit 41. The PSD opening driver processing is repeatedly executed by the control unit 41 at a predetermined cycle when at least one of the right PSD operation switch 25 and the left PSD operation switch 24 is opened. Furthermore, since the processing when the left PSD operation switch 24 is opened is the same as the processing when the right PSD operation switch 25 is opened, only the processing when the left PSD operation switch 24 is opened will be described here.

[0048] like Figure 5 As shown, when the left PSD operation switch 24 is turned on, the control unit 41 first determines whether the left PBD operation switch 30 has been operated (step S1). That is, the control unit 41 determines whether the left PBD operation switch 30, which is also located on the left side of the vehicle 11, has been operated. If the determination result in step S1 is negative, the control unit 41 terminates the PSD turning-on process after driving the left PSD motor 20 to turn on the left PSD 16 (step S2).

[0049] On the other hand, in the case where the determination result in step S3 is affirmative, the control section 41 determines whether the position of the left PSD 16 is located on the full-closing position side from the reference position (step S4). In the case where the determination result in step S4 is negative, the control section 41 stops the left PSD motor 20 after the left PSD 16 is stopped (step S5), and ends the PSD opening drive processing routine.

[0050] Here, in the case where the left PSD 16 is located at the reference position in step S3, the control section 41 stops the left PSD motor 20 so that the left PSD 16 is stopped in step S4. Further, in the case where the left PSD 16 is located on the full-opening position side from the reference position in step S3, the control section 41 prohibits the drive of the left PSD motor 20 so that the left PSD 16 is not driven to be opened in step S4.

[0051] On the other hand, in the case where the determination result in step S3 is affirmative, the control section 41 drives the left PSD motor 20 so that the left PSD 16 is driven to be opened after the left PSD 16 is driven to be opened (step S5), and ends the PSD opening drive processing routine.

[0052] Further, as for the description of the case where the right PSD operation switch 25 is operated to be opened, another expression is used as follows in the description of the flowchart of the PSD opening drive processing routine shown in FIG. 6. That is, the left PSD operation switch 24 is referred to as the right PSD operation switch 25, the left PSD motor 20 is referred to as the right PSD motor 21, and the left PSD 16 is referred to as the right PSD 17, and another expression is used. Figure 5

[0053] Next, the execution manner of the PSD opening drive processing and the effects brought by the execution of the processing will be described.

[0054] Figure 6 (a) to (d) in FIG. 8 show the execution manner of the PSD opening drive processing in the case where the left PSD operation switch 30 is operated during the movement of the left PSD 16 to the full-opening position side and the left PSD 16 is located on the full-closing position side from the reference position.

[0055] In the example shown in FIG. 9, when the left PSD motor 20 is activated by the operation of the left PSD operation switch 24 at time tl, the left PSD 16 starts to move toward the full-opening position. When the left PSD operation switch 30 is operated during the movement of the left PSD 16 at time t2 before the left PSD 16 reaches the reference position, the activated state of the left PSD motor 20 is maintained until the left PSD 16 reaches the reference position. Figure 6

[0056] ​​When the left PSD16 reaches the reference position at time t3, the left PSD motor 20 stops, and the left PSD16 stops at the reference position. Therefore, as Figure 3 As shown, the movement of the left PSD16 to the fully open position is restricted before the reference position, so that the left PSD16 can be prevented from contacting the passenger P who operates the left PSD operation switch 24.

[0057] Figure 7 (a) to (d) show the execution mode of the PSD opening drive process when the left PBD operation switch 30 is operated while the left PSD16 moves to the fully open position and the left PSD16 is located closer to the fully open position than the reference position.

[0058] exist Figure 7 In the example shown, when the left PSD operation switch 24 is opened at time t1, causing the left PSD motor 20 to start, the left PSD 16 begins to move towards the fully open position. At time t2, when the left PSD 16 is located closer to the fully open position than the reference position, if the left PBD operation switch 30 is operated during the movement of the left PSD 16, the left PSD motor 20 immediately stops, and the left PSD 16 immediately stops. Therefore, contact between the left PSD 16 and the passenger P who operates the left PSD operation switch 24 can be prevented.

[0059] Figure 8 (a) to (d) show the execution mode of the PSD opening drive process when the left PSD16 is moved to the fully open position side during the operation of the left PBD operation switch 30 and the left PSD16 is located on the fully closed position side closer to the reference position.

[0060] exist Figure 8 In the example shown, when the left PBD operation switch 30 is turned on at time t1, PBD 26 performs an opening and closing operation. At time t2, when the left PSD 16 is in the fully closed position (closer than the reference position), the left PSD operation switch 24 is turned on, activating the left PSD motor 20. The left PSD 16 then begins to move towards the fully open position. The left PSD motor 20 remains activated until the left PSD 16 reaches the reference position.

[0061] When the left PSD16 reaches the reference position at time t3, the left PSD motor 20 stops, and the left PSD16 stops at the reference position. Therefore, as Figure 3 As shown, the movement of the left PSD16 to the fully open position is restricted before the reference position, so that the left PSD16 can be prevented from contacting the passenger P who operates the left PSD operation switch 24.

[0062] Figure 9(a) to (d) in FIG. 10 show the execution of the PSD opening drive process in the case where the left PSD 16 is moved to the full opening position side in the operation of the left PBD operation switch 30 and in the case where the left PSD 16 is at the reference position or on the full opening position side of the reference position.

[0063] In Figure 9 In the example shown in FIG. 10, when the left PBD operation switch 30 is turned on at time t1, the PBD 26 performs the opening and closing operation. When the left PSD operation switch 24 is operated to be turned on at time t2 in the case where the left PSD 16 is at the reference position or on the full opening position side of the reference position, the drive of the left PSD motor 20 is prohibited, and the movement of the left PSD 16 to the full opening position side is prohibited. That is, at time t2, even if the left PSD operation switch 24 is operated to be turned on, the stop state of the left PSD 16 is maintained. Therefore, it is possible to suppress the contact of the left PSD 16 with the passenger P who operates the left PSD operation switch 24.

[0064] Further, as for the description of the case where the right PSD operation switch 25 is operated to be turned on, another expression can be used as follows in the description of the timing chart showing one example of the execution of the PSD opening drive process described above. That is, another expression can be used by replacing the left PSD operation switch 24 with the right PSD operation switch 25, the left PSD motor 20 with the right PSD motor 21, the left PSD 16 with the right PSD 17, and the left PBD operation switch 30 with the right PBD operation switch 31. Figure 6 to 9

[0065] In addition, in the case where the right PBD operation switch 31 is operated after the left PSD operation switch 24 is operated to be turned on or in the case where the left PSD operation switch 24 is operated to be turned on after the right PBD operation switch 31 is operated, the movement of the left PSD 16 to the full opening position side is not prohibited or restricted. Similarly, in the case where the left PBD operation switch 30 is operated after the right PSD operation switch 25 is operated to be turned on or in the case where the right PSD operation switch 25 is operated to be turned on after the left PBD operation switch 30 is operated, the movement of the right PSD 17 to the full opening position side is not prohibited or restricted.

[0066] That is, in the case where one of the left PBD operation switch 30 and the right PBD operation switch 31 is operated, the movement of the PSD provided on the side portion of the vehicle 11 on which the operated one switch is provided to the full opening position side based on the drive of the PSD motor is prohibited or restricted.

[0067] According to the above-described embodiments, the following effects can be obtained.

[0068] ​(1) In the door opening and closing device for a vehicle, the control section 41 prohibits or restricts the left PSD 16 from moving to the fully open position side based on the driving of the left PSD motor 20 in the case where the left PBD operation switch 30 is operated. According to this structure, when the passenger P operates the left PBD operation switch 30 to cause the PBD 26 to perform the opening and closing operation, the movement of the left PSD 16 to the fully open position side is prohibited or restricted, so it is possible to suppress the left PSD 16 from contacting the passenger P who operates the left PBD operation switch 30.

[0069] (2) In the door opening and closing device for a vehicle, the control section 41 controls the driving of the left PSD motor 20 so that the left PSD 16 stops at the reference position in the case where the left PBD operation switch 30 is operated in the movement of the left PSD 16 to the fully open position side and the left PSD 16 is positioned on the fully closed position side from the reference position. According to this structure, it is possible to avoid the left PSD 16 from contacting the passenger P who operates the left PBD operation switch 30, and it is possible to enable another passenger P to get on and off the vehicle 11 from the passenger step 18.

[0070] (3) In the door opening and closing device for a vehicle, the control section 41 controls the left PSD motor 20 so that the left PSD 16 immediately stops in the case where the left PBD operation switch 30 is operated in the movement of the left PSD 16 to the fully open position side and the left PSD 16 is positioned on the fully open position side from the reference position. According to this structure, it is possible to suppress the left PSD 16 from contacting the passenger P who operates the left PBD operation switch 30, and it is possible to enable another passenger P to get on and off the vehicle 11 from the passenger step 18.

[0071] (4) In the door opening and closing device for a vehicle, the control section 41 controls the left PSD motor 20 so that the left PSD 16 stops at the reference position in the case where the left PSD 16 is moved to the fully open position side by the operation of the left PBD operation switch 30 and the left PSD 16 is positioned on the fully closed position side from the reference position. According to this structure, it is possible to suppress the left PSD 16 from contacting the passenger P who operates the left PBD operation switch 30, and it is possible to enable another passenger P to get on and off the vehicle 11 from the passenger step 18.

[0072] (5) In the door opening and closing device for a vehicle, the control section 41 controls the left PSD motor 20 so that the movement of the left PSD 16 to the fully open position side is prohibited in the case where the left PSD 16 is moved to the fully open position side by the operation of the left PBD operation switch 30 and the left PSD 16 is positioned at the reference position or on the fully open position side from the reference position. According to this structure, it is possible to suppress the left PSD 16 from contacting the passenger P who operates the left PBD operation switch 30 even if the left PSD 16 is positioned at the reference position or on the fully open position side from the reference position.

[0073] (6) In the door opening and closing device for a vehicle, the control section 41 prohibits or restricts movement of the PSD provided on the side portion of the vehicle 11 on which the operated one of the left and right PBD operation switches 30 and 31 is provided to the full opening position side based on the drive of the PSD motor in the case where one of the left and right PBD operation switches 30 and 31 is operated. According to this structure, in the case where the passenger P operates either of the left and right PBD operation switches 30 and 31, the PSD can be prevented from contacting the passenger P.

[0074] Further, in the above (1) to (5), in the case where the passenger P operates the right PBD operation switch 31, the left PBD operation switch 30 can be referred to as the right PBD operation switch 31, the left PSD motor 20 can be referred to as the right PSD motor 21, and the left PSD 16 can be referred to as the right PSD 17 by using another expression.

[0075] (Alterations)

[0076] The above embodiment can be implemented by being changed as follows. In addition, the above embodiment and the following alterations can be implemented by being combined with each other within a range in which they are not technically contradictory.

[0077] • Either of the left and right PSDs 16 and 17 can be changed to a door that does not move in the vehicle front and rear direction X, such as a hinged door.

[0078] • The control section 41 does not necessarily control the left PSD motor 20 so that movement of the left PSD 16 to the full opening position side is prohibited in the case where the left PSD 16 is located on the full opening position side from the reference position in the case where the left PBD operation switch 30 is operated.

[0079] • The control section 41 does not necessarily control the left PSD motor 20 so that the left PSD 16 stops at the reference position in the case where the left PSD 16 is located on the full closing position side from the reference position in the case where the left PBD operation switch 30 is operated.

[0080] • The control section 41 does not necessarily control the left PSD motor 20 so that the left PSD 16 immediately stops in the case where the left PSD 16 is located on the full opening position side from the reference position in the case where the left PBD operation switch 30 is operated in the movement of the left PSD 16 to the full opening position side.

[0081] • The control section 41 does not necessarily control the left PSD motor 20 so that the left PSD 16 stops at the reference position in the case where the left PSD 16 is located on the full closing position side from the reference position in the case where the left PBD operation switch 30 is operated in the movement of the left PSD 16 to the full opening position side.

[0082] • The operation object is not limited to the PBD 26, and can be, for example, a lid of a fuel tank or the like that is opened and closed by the operation section.

[0083] • The operation object can also be a rear door that is mechanically opened and closed by operation of the operation section and using the elastic force of a spring, for example.

[0084] • The control section 41 can also be such that, in the case where the left PBD operation switch 30 is operated in the movement of the left PSD 16 to the fully open position side and the left PSD 16 is positioned on the fully closed position side from the reference position, the movement speed of the left PSD 16 to the reference position is slower than normal.

[0085] • The control section 41 can also be such that, in the case where the left PBD operation switch 30 is operated in the movement of the left PSD 16 to the fully open position side and the left PSD 16 is positioned on the fully closed position side from the reference position, the buzzer is caused to sound until the left PSD 16 reaches the reference position.

[0086] • The control section 41 can also be such that, in the case where the left PBD operation switch 30 is operated when the left PSD 16 is positioned on the fully closed position side from the reference position, the drive of the left PSD motor 20 is prohibited even if the left PSD operation switch 24 is opened. That is, the control section 41 can also be such that, in the case where the left PBD operation switch 30 is operated when the left PSD 16 is positioned on the fully closed position side from the reference position, the left PSD 16 is prohibited from moving to the fully open position side even if the left PSD operation switch 24 is opened.
