Abstract:
1. An electric steering lock apparatus for locking a steering shaft, the steering lock apparatus comprising: a lock pin engageable with the steering shaft to lock the steering shaft; an actuator for moving the lock pin between a lock position in which the lock pin is engaged with the steering shaft and an unlock position in which the look pin is disengaged from the steering shaft; and a control unit for controlling the actuator, wherein the control unit generates a calculated value related to operation time of the actuator and suspends operation of the actuator when the calculated value is greater than a predetermined operation suspension threshold value, wherein the control unit controls the actuator in accordance with an actuator operation request and invalidates the actuator operation request when the calculated value is greater than an invalidation threshold value that is less than the operation suspension threshold value.
