Smart entry system for vehicle
In a lock-out prevention control, in which when a portable device is locked out in a trunk room, an alarm is conducted and a latch of a trunk latch mechanism is controlled to its unlatch state without ID verification with a portable device, in the case where an operation of door lock is conducted by the portable device after a start of the alarm (step SB 8 ), the alarm is stopped (step SB 12 ) and the lock-out prevention control is prohibited. The lock-out prevention control is also prohibited when a switch located in a vehicle cabin is operated (step SB 9 ) regardless of the door lock operation by the portable device. Thereby, the vehicle security and the utility or facility can be improved.
