  According to such a configuration, the kick sensor 300 provided in the lower portion of the door body 21 performs the opening / closing operation of the rear door 30 by detecting the proximity of the occupant's foot, while the detection mode of the kick sensor 300 in the opening / closing operation. The reservation operation is performed by detecting the proximity of the occupant in a detection mode different from the above. Therefore, the occupant can perform the opening / closing operation of the rear door 30 and the reservation operation even when both hands are blocked by luggage or the like. Further, since the common kick sensor 300 can perform the opening / closing operation and the reservation operation of the rear door 30, the usability can be improved.

<Example of change>
The above embodiment can be modified and implemented as follows. The above embodiment and the following modifications can be implemented in combination with each other within a technically consistent range.

  If it is not determined in step S2 of the flowchart shown in FIG. 5 that the occupant is not present in the vehicle 200 (step S2: NO), that is, if the occupant is present in the vehicle 200, the determination process of step S2 is performed as predetermined. It may be repeatedly executed with the time as the upper limit.

  In step S3 of the flowchart shown in FIG. 5, if a process of determining whether or not the electronic key 210 exists outside the detection area Z1 of the antenna 90 continues for a predetermined time or more, the series of processes is terminated. May be.

  The reservation operation may be performed when the rear door 30 is fully closed. Even in this case, when the electronic key 210 moves from the inside of the detection area Z1 to the outside of the detection area Z1 after the rear door 30 is slid to the fully open position after the reservation operation is performed, the rear door 30 is driven to close. The door drive motor 61 may be driven to perform the above.

The reservation operation may be performed while the rear door 30 is moving in the closing direction.
The reservation operation may be canceled after the reservation operation is performed, for example, by operating the operation switch 32b again or by detecting the foot of the occupant again by the kick sensor 300.

  The horn device 130 may generate a notification sound to notify that when the reservation operation is performed, or when the reservation operation is performed and the rear door 30 is locked. A notification sound may be generated at each time.

  The notification unit is not limited to the horn device 130. The notification unit may be a unit that gives a notification in a mode other than the notification sound, for example, blinking a hazard lamp or storing a side mirror.

  The reservation operation section is composed of the operation switch 32b and the kick sensor 300, and performs the reservation operation by operating the operation switch 32b and detecting the proximity of the passenger to the kick sensor 300 by the kick sensor 300. May be For example, when the reservation operation unit is configured by only the kick sensor 300, the reservation operation may be performed against the occupant's intention when the occupant puts his / her foot between the vehicle and the ground. In this respect, according to the above configuration, the reservation operation is performed by operating the operation switch 32b and detecting the proximity of the occupant's foot by the kick sensor 300. Therefore, it is possible to prevent the reservation operation from being performed against the intention of the occupant.

  In the second embodiment, the reservation operation detection mode is not limited to the mode in which the proximity of the occupant's foot is detected twice by the kick sensor 300 within a predetermined time. Alternatively, for example, the kick sensor 300 may detect the proximity of the occupant's foot three times or more within a predetermined time, or may detect the occupant's foot for a predetermined time or more.

The kick sensor 300 may be provided, for example, below the door body 31 of the rear door 30.
-A plurality of kick sensors 300 may be provided in the front-rear direction. In this case, the opening and closing operation of the rear door 30 is performed by detecting the proximity of the occupant's foot by only one kick sensor 300, while the proximity of the occupant's foot is sequentially detected by the kick sensors 300 in the front-rear direction. Thus, that is, the reservation operation may be performed by detecting that the foot of the occupant has moved in the front-rear direction. Further, for example, the proximity of the occupant's foot is detected by the predetermined kick sensor 300, and the rear door 30 is opened / closed. The reservation operation may be performed by being detected.

  The kick sensor 300 does not perform the opening / closing operation of the door body 31, but may perform only the reservation operation. That is, the reservation operation unit may be configured by only the kick sensor 300, and the door operation unit 32 may be configured by only the door handle 32a and the operation switch 32b.

  The proximity sensor provided on the side of the vehicle 200 may be used as the reservation operation unit. In this case, the occupant can perform a reservation operation by moving to the side of the proximity sensor. Therefore, the occupant can perform the reservation operation for the rear door 30 even when both hands are blocked by luggage or the like.

  The proximity sensor is not limited to the one that detects the proximity of the occupant by detecting the change in the electrostatic capacitance between the sensor electrode and the occupant. Alternatively, for example, an infrared sensor or an ultrasonic sensor may be used.

  In the first embodiment, the operation mode of the reservation operation is not limited to the mode in which the operation switch 32b is operated twice within the predetermined time. Alternatively, for example, the operation switch 32b may be operated three times or more within a predetermined time, or the operation switch 32b may be pressed for a predetermined time or more, that is, a so-called long press may be performed.

The reservation operation unit is not limited to the operation switch 32b and the kick sensor 300, and may be a switch provided in the electronic key 210, a switch provided in the vehicle 200, or the like.
The operation switch 32b is not limited to the push button type switch, but may be, for example, a capacitance type switch.

  The occupant detection unit is not limited to the seat sensor 51. Alternatively, for example, a camera or an infrared sensor that detects movement of an occupant may be used. In this case, when an object other than the occupant such as luggage is placed on the seat cushion 50a, it is possible to prevent the seat sensor 51 from erroneously recognizing the object as the occupant.

-The occupant detection unit can be omitted.
The application target of the vehicle door reservation closing device according to the present invention is not limited to the sliding door. Alternatively, for example, as shown in FIG. 8, the present invention can be applied to the back door 40. In this case, if a rear part (for example, a rear bumper) of the body 201 is provided with an antenna that forms the detection area Z2, a reserved closing device for the back door 40 can be realized in the same manner as the above embodiment.
