  • Patent number: 7327050
    Abstract: An electric steering lock device is configured with a control unit to operate a steering column lock between a steering locked state and a steering unlocked state. The electric steering lock device has a locking limit switch that turns on when a locking member reaches the locking stop position, and turns off when an unlocking command for the locking member is outputted. An unlocking limit switch of the electric steering lock device turns on when the locking member reaches the unlocking stop position, and turns off when a locking command for the locking member is outputted. The electric steering lock control unit determines that the locking limit switch or the unlocking limit switch has malfunctioned based on the state of the locking member.

  • Patent number: 7262518
    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.
