Therefore, the occupant may open the door 11 by pulling or pressing and moving a part of the door 11 without pulling the door knob, and get in, load luggage, or carry a child.
[0064]
[When all door locks are unlocked and the corresponding door is half-opened]
[0065]
When all the door locks are unlocked and the door 11 provided with the request switches 111 and 112 is half-opened, the passenger approaches the door 11 with the portable device 32 and shortens the request switches 111 and 112 by one. Press twice. The presence of this input is determined in step S1, and authentication is performed in steps S8 and S9. If the authentication is successful, the door lock of only the corresponding door 11 is unlocked in step S10. Furthermore, if the request switches 111 and 112 are pressed once long within the predetermined time, this is determined in step S12, and the process proceeds to step S14, where the doors other than the corresponding door 11 are unlocked. Thereby, all the doors 11 are unlocked. Further, the process proceeds to step S15, and the corresponding door 11 is half-opened. Therefore, the passenger only has to pull a part of the door 11 without pulling the door knob, open the door 11 so as to move it while pressing, move in, put in luggage, carry a child, and so on. Since the door lock is unlocked, the passenger only has to pull the door knob to open the door 11 and get on.
[0066]
Further, in the first embodiment, only the corresponding door 11 is half-opened in consideration of the improvement of safety. However, the door may be half-opened for all the doors 11 for further convenience. The case is also included in the first embodiment.
[0067]
In the first embodiment, the door half-opening means may also serve as the door unlocking means, or may be separate from the door lock. FIGS. 5 and 6 show an example in which the door half-opening means also functions as the door unlocking means. A slide shaft 211 that slidably engages with the fork pin rotating shaft 44 to rotate the rotating shaft is provided. The clutch disc 212 is attached to the slide shaft 211. The clutch disk 212 is provided with a fan-shaped opening 213 and a through hole 214. Further, the motor 45 or the motor 46 is provided with a small fan-shaped engaging portion 215 that can be fitted into the opening 213 on the output shaft. Further, a lock pin 216 is provided at a position overlapping with the through hole 214 in a state where the clutch disc 212 rotates together with the fork pin 4 to lock the door. Further, a linear solenoid 218 having a spring 217 for pressing the clutch disk 212 toward the motor and an advancing / retracting pin for advancing / retreating the clutch disk 212 biased by the spring toward the fork pin is provided.
[0068]
In this structure, the door is locked and released by the forward and backward pins of the linear solenoid 218 advance and retract to three positions P1, P2, and P3 as shown in FIG.
[0069]
First, in a state where the door is open, the clutch board 212 is in a free state at the position P1, so that the strike pin 7 and the fork pin 4 can be easily engaged by closing the door. Next, in a state where the door is closed, the advance / retreat pin is retracted, the clutch disc is moved to the position P2 by the spring 217, the opening 213 is engaged with the engaging portion 215, and the motor is driven via the clutch disc 212. The fork pin 4 can be rotated, and the door is fully closed by rotating the fork pin 4 from the half-latched state. When the door is fully closed in this manner, the rotational position of the clutch disc 212 is a fixed position because the strike pin 7 is engaged with the recess of the fork pin 4. In this state, since the through-hole 214 and the lock pin 216 are located at the overlapping position, the advance / retreat pin is further retreated to bring the clutch disc 212 into the P3 state, the lock pin 216 is inserted into the through-hole 214, and the clutch disc cannot be rotated. Thus, the door is locked while keeping the state of the fork pin 4 and the strike pin 7 unchanged. When the door is half-opened, the fork pin 4 can be rotated by the motor and the lock pin 216 and the through hole 214 can be prevented from engaging with each other by setting the clutch board 212 to the P2 state. If the door is half-opened by rotating the door 4, the door can be half-opened while suppressing complication of the mechanism.
