Abstract
An electric steering lock apparatus that protects an actuator from overheating without enlarging the actuator. The electric steering lock apparatus includes a lock pin engaged with a steering shaft to lock the steering shaft. An actuator moves 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 lock pin is disengaged from the steering shaft. A control unit controls the actuator. 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.
