ABSTRACT:
A door lock/unlock system for a vehicle is comprised of a door lock state detector for detecting a door lock/unlock state, a door open state detector for detecting a door open/close state, a door lock mechanism for locking and unlocking a door, and a controller. The controller is arranged to compare a first lock/unlock state detected during the door open state with a second lock/unlock state detected at a moment when an open/close state is changed from an open state to a closed state, to maintain the state of the door lock mechanism when the first lock/unlock state corresponds to the second lock/unlock state, and to set the state of the door lock mechanism at the first lock/unlock state when the first lock/unlock state does not corresponds to the second lock/unlock state.
