  • a door lock state detector detecting whether a door of the vehicle is put in a lock state;

    a door open state detector detecting whether the door is open;

    a door lock mechanism through which the door is locked and unlocked; and

    a controller connected to the door lock state detector, the door open state detector and the door actuator, the controller being 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.
