  Next, a control flow for door opening by the sliding door opening and closing device will be described based on the flowchart shown in FIG.

  First, when a user having a portable device such as a key approaches the vehicle 1 (step S1), the owner ID is checked by wireless communication between the portable device and the KOS, that is, key authentication is performed (step S1). S2). When the key authentication is not performed in step S2 (step S2; No), the process returns to step S1, the key authentication is performed (step S2; Yes), and when the user approaches the slide door 6 (step S3), The presence or absence of a person is confirmed by the ultrasonic sensor 21 (step S4). If the presence is not confirmed in step S4 (step S4; No), the process returns to step S1, and if the presence of a person is confirmed (step S4; Yes), the process proceeds to step S5. In step S5, when the user close to the vehicle 1 performs a prescribed motion with his / her foot, the motion sensor 22 detects the prescribed motion (step S6), and if the prescribed motion corresponding to opening is not confirmed (step S6). S6; No), the process returns to step S1, and when the specified operation corresponding to opening is confirmed (step S6; Yes), the locked state of the vehicle is confirmed (step S7), and in the unlocked state (step S7). No) As it is, in the locked state (step S7; Yes), after releasing the lock (step S8), the slide door is opened (step S9).

  Next, a control flow for door closing by the sliding door opening and closing device will be described based on the flowchart shown in FIG.

  First, it is determined whether or not the slide door is in an open state (step S11). If the slide door is in a closed state in step S11 (step S11; No), the process returns to the original state, and in step S11, the slide door is in an open state ( Step S11; Yes) When a user with a portable device such as a key approaches the vehicle (Step S12), the owner ID is checked by wireless communication between the portable device and the KOS, that is, key authentication is performed. It performs (step S13). When the key authentication is not performed in step S13 (step S13; No), the process returns to step S11, the key authentication is performed (step S13; Yes), and when the user approaches the slide door 6 (step S14), The presence or absence of a person is confirmed by the ultrasonic sensor 21 (step S15). If the presence is not confirmed in step S15 (step S15; No), the process returns to step S11. If the presence of a person is confirmed (step S15; Yes), the process proceeds to step S16. In step S16, when a user close to the vehicle 1 performs a prescribed motion with his / her foot, the prescribed motion is detected by the motion sensor 22 (step S17), and when the prescribed motion due to opening is not confirmed (step S17; No), the process returns to step S11, and when the specified operation corresponding to opening is confirmed (step S17; Yes), the slide door is closed (step S18).

  In the flow control in FIGS. 4 and 5, the key authentication by the keyless entry device in step S2 or step S13 may be omitted, or even if the key authentication is performed, the confirmation of the lock state in steps S7 and S8 and the lock Release may be omitted. In the flow without unlocking, the sliding door opening / closing device opens the sliding door only when the unlocking is performed, that is, the unlocking is premised on the assumption that the sliding door is opened. However, safety is improved.

  Further, in the above flow control, when no person is detected in step S4 or step S15 (step S4; No or step S15; No), the process may return to step S4 or step S15. If the specified operation is not detected in step S6 or step S17 (step S6; No or step S17; No), the process may return to step S6 or step S17.

  Further, although not described in the control flow of FIGS. 4 and 5, as a premise of the flow control described above, it is a matter of course that the vehicle 1 is detected to be stopped.
