Patent ID: 7362006

Claim:
A steering lock for locking a steering shaft of a vehicle, the steering lock comprising: an actuator; a lock member driven by the actuator to engage and lock the steering shaft; and a control unit for controlling the actuator, the control unit controlling the actuator to generate drive force acting in a direction to urge the lock member to move from a lock position in which the lock member engages the steering shaft to an unlock position in which the lock member is disengaged from the steering shaft, wherein the control unit uses the drive force to move the lock member from the lock position to the unlock position, and controls the actuator to continuously generate the drive force acting in said direction to urge the lock member to move to the unlock position even after the lock member has moved to the unlock position, and decreases current flowing to the actuator after the lock member has moved to the unlock position as the actuator continuously generates the drive force acting in the direction to urge the lock member to move to the unlock position with less power.
