When an opening / closing command signal is input from the portable terminal 22 in step S1, it is determined in step S2 whether there is an obstacle in the opening / closing area of the rear seat door 12b based on the detection signal from the obstacle sensor 24. . When it is confirmed in step S2 that there is no obstacle in the open / close region of the rear seat door 12b, an automatic opening operation of the rear seat door 12b is started in step S3. At this time, the front seat door 12a is maintained in a stopped state. When an obstacle is detected in step S2, the routine returns to step S1, and the doors 12a and 12b are maintained in a stopped state until an opening / closing command signal is input again.

  When the automatic opening operation of the rear seat door 12b is started in step S3, it is determined in step S4 whether or not there is an obstacle in the open / close region of the operating rear seat door 12b, and no obstacle is detected in step S4. The operation of automatically opening the rear seat door 12b is continued until it is determined in step S5 that the rear seat door 12b is fully opened. When it is determined in step S5 that the rear seat door 12b is fully opened, the operation of the rear seat door 12b is stopped in step S6. If an obstacle is detected in step S4, the automatic closing operation of the rear seat door 12b is stopped in step S7, the routine is returned to step S2, and it is determined in step S2 that there is no obstacle. The rear seat door 12b is maintained in a stopped state.

  When the rear seat door 12b reaches the fully open position and stops, next, in step S8, it is determined whether or not the rear seat area detection sensor inputs the rear seat area, and in step S9, the rear seat door 12b and the front seat are determined. The presence or absence of an obstacle in each open / close region of the door 12a is determined. If it is determined in step S8 that there is no area detection input, that is, there is no operator in the rear seat, and it is determined in step S9 that there are no obstacles in the open / close regions of the doors 12a and 12b, in step S10 The automatic closing operation of the rear seat door 12b is started, and the automatic opening operation of the front seat door 12a for the driver's seat is started.

  In the present embodiment, the front seat door 12a is automatically opened when the rear seat door 12b is automatically closed. However, the present invention is not limited to this, and the front seat door 12a is automatically opened. The start timing may be shifted, for example, earlier or later than the start timing of the automatic closing operation of the rear seat door 12b.

  When the front seat door 12a starts an automatic opening operation and the rear seat door 12b starts an automatic closing operation in step S10, it is determined in step S11 whether there is an obstacle in the open / close region of each door 12a, 12b. If an obstacle is detected in one of the open / close regions of each door 12a, 12b in step S11, both the front seat door 12a and the rear seat door 12b are stopped in step S12, and there is no obstacle in step S9. Each door 12a, 12b is maintained in a stopped state until it is determined. In other words, in this opening / closing device 14, when an obstacle is detected in the opening / closing region of any door 12a, 12b that opens and closes in the interlock mode by the obstacle sensor 24, all doors that are sequentially opened and closed in the interlock mode. The opening / closing operation of the doors 12a and 12b is stopped to improve the safety of the opening / closing device 14 when the doors 12a and 12b are driven to open and close.

  Thus, in this opening / closing device 14, when there is an obstacle in the opening / closing area of either the front seat door 12a or the rear seat door 12b that is sequentially opened / closed in the interlock mode, the opening / closing operation of both the doors 12a, 12b is performed. Since the operation is stopped, the safety of the opening / closing device 14 when the two doors 12a and 12b are sequentially opened / closed in the interlock mode can be improved.

  In step S11, if it is determined in step S13 that the front seat door 12a has reached the fully open position and the rear seat door 12b has reached the fully closed position without an obstacle being detected, in step S14, the front seat door and rear The operation of the seat door is stopped. When the front seat door 12a stops in the fully open state and the rear seat door 12b stops in the fully closed state, in step S15, it is determined whether or not there is an area detection input of the driver seat by the driver seat area detection sensor. In step S16, it is determined whether there is an obstacle in the opening / closing area of the front seat door 12a. If it is determined in step S15 that there is an area detection input, that is, the operator has boarded the driver's seat, and if it is determined in step S16 that there is no obstacle in the opening / closing area of the front seat door 12a, then in step S17 The automatic closing operation of the front seat door 12a is started.

  When the automatic closing operation of the front seat door 12a is started in step S17, it is determined in step S18 whether or not there is an obstacle in the open / close region of the front seat door 12a in operation, and no obstacle is detected in step S18. In step S19, the automatic closing operation of the front seat door 12a is continued until it is determined that the front seat door 12a is fully closed. If it is determined in step S19 that the front seat door 12a is fully closed, the operation of the front seat door 12a is stopped in step S20, and the automatic opening / closing operation in the interlock mode is ended. If an obstacle is detected in step S18, the automatic closing operation of the front seat door 12a is stopped in step S21, the routine is returned to step S16, and it is determined in step S16 that there is no obstacle. The front seat door 12a is maintained in a stopped state.

  As described above, in the opening / closing device 14, when the door opening / closing operation is commanded in a state in which the interlock mode is set by the mode setting unit 22b provided in the portable terminal 22, the rear seat door 12b and the front seat Since the door 12a is opened and closed sequentially, the operability of the portable terminal 22 when the two doors 12a and 12b are successively opened and closed can be improved. In particular, when the front door 12a and the rear door 12b for the driver's seat provided on one side of the vehicle 11 are sequentially opened and closed, when a driver holding a baggage approaches the vehicle 11 due to shopping or the like. After the rear seat door 12b is opened and the luggage is mounted on the rear seat, the rear seat door 12b is automatically closed and the front seat door 12a for the driver's seat is opened. When the driver gets on the driver's seat, the front seat door is opened. Since 12a will be closed, a driver | operator's operation | movement can be supported without stress by operation of the portable terminal 22 simple. Furthermore, since the operation of the mobile terminal is simplified, the operator can quickly operate, and the wetness in the vehicle can be minimized when it is raining.

  FIG. 6 is a flowchart showing a control procedure in the half-door prevention mode. In this opening / closing device 14, when one of the doors is automatically opened by operating the opening / closing command unit 22a of the portable terminal 22, When there is another door in a state, the half door is automatically closed to prevent the half door. Hereinafter, the control procedure of the half door prevention mode will be described with reference to FIG.

  First, under the state in which the half-door prevention mode is set by the mode setting unit 22b, when an opening operation command signal for a desired door is input from the portable terminal 22 to the control device 21 in step S1, the corresponding operation is performed in step S2. It is determined whether or not there is a door other than the operating door that is in a half-door state. In step S2, the half door state is determined based on a detection signal from a half latch switch or the like of a door lock mechanism (not shown) provided in each of the doors 12a to 12d or the vehicle 11. When another door in the half door state is detected in step S2, the automatic closing operation of the other door in the half door state is started in step S3, and until it is determined in step S4 that the half door is fully closed. The automatic closing operation continues. If it is determined in step S4 that the half door is fully closed, the automatic door closing operation that was in the half door state is stopped in step S5.

  If no other door in the half-door state is detected in step S2, this control is terminated, and only the automatic opening operation for which the automatic opening operation is commanded by the portable terminal 22 is performed.

  Thus, in the opening / closing device 14, when there is another door that is in a half-door state when any of the doors 12a to 12d is automatically opened, the half-door is automatically fully closed. Therefore, for example, even when the operator mistakenly operates the open / close command unit 22a of the portable terminal 22 and sets a door different from the desired door to a half-door state, the operator automatically opens the desired door. Since the door that has become a half-door when it is operated is automatically closed, it is not necessary to perform another operation to close the door that is in a half-door state, and the operability of the opening / closing device 14 can be improved. .

  In the half-door prevention mode shown in the present embodiment, when the other door different from the door for which the automatic opening operation is commanded is in the half-door state, the half-door is fully closed. Not limited to this, as long as the other door is opened, the automatic closing operation may be performed regardless of the opening degree.

  Further, the half door prevention mode is selectively set by the mode setting unit 22b, but can be set simultaneously with the above-described interlocking mode.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the present embodiment, the opening / closing body is a laterally opening type door 12a to 12d provided on the side portion of the vehicle 11, but is not limited thereto, for example, a sliding door or vehicle that opens and closes in the vehicle front-rear direction. It may be a trunk lid, a back door or the like attached to the rear end.

  In the present embodiment, the front seat door 12a and the rear seat door 12b are sequentially opened and closed in the interlock mode. However, the present invention is not limited to this, and if multiple doors are opened and closed sequentially, the target The number of doors, the number of doors, and the operation pattern are not limited. Further, not only the doors 12a to 12d but also the trunk lid and the doors 12a to 12d may be sequentially opened and closed in a predetermined pattern. For example, when the trunk lid and the front seat door 12a for the driver's seat are operated in the interlock mode, the portable terminal can be easily operated when boarding the driver's seat after the luggage is loaded on the trunk. The operation can be supported without stress.

  Further, in the present embodiment, the portable terminal 22 is configured to transmit an opening / closing command signal in a state where the calling signal from the transceiver 23 is received. An open / close command signal may be transmitted when operated.

  Further, in the present embodiment, the drive unit 15 is disposed inside the doors 12a to 12d, and the power is converted into the opening / closing drive force of the doors 12a to 12d via the drive rod 18. However, the present invention is not limited to this, and other structures may be used as long as the doors 12a to 12d are automatically opened and closed by a driving source.

  Furthermore, in this embodiment, the obstacle sensor 24, which is a clearance sonar using infrared rays, is used as the obstacle detection means. However, the present invention is not limited to this, and a clearance sensor using other media such as radio waves is used. Moreover, you may make it detect an obstruction from the change of the load of the electric motor 16, etc. which arise when doors 12a-12d contact an obstruction. Moreover, you may make it provide the approaching object detection sensor which detects the obstruction which approaches from the front, back, or the side of the vehicle 11 not only in the opening / closing area | region of the doors 12a-12d.

  Furthermore, in the present embodiment, the driver seat area detection sensor detects that there is an operator such as a driver in the driver seat, but the present invention is not limited to this, and a seating sensor provided in the driver seat is used. You may make it detect.
