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.

Electric steering lock device and method thereof

A device and method of notifying operation of a vehicle closure member is disclosed having a door drive motorfor driving a vehicle closure member, mounted in a vehicle, between an open position and a closed position, a pulse encoderdetecting a closure position of the vehicle closure member, and a notifying unitnotifying a user of operation of the vehicle closure member, with control being executed to apply a motor brake on the vehicle closure member at a time instant t, upon recognition of operation for reverse movement when the closure position detected with the pulse encoderremains in an area-just-prior-to-fully-closed-position between a half-latch position and the open position, whereupon a buzzer is activated at a time instant twith the motor brake being terminated when the vehicle closure member remains in the area-just-prior-to-fully-closed-position.
