Apparatus and method for warning against lack of stroke for electronic parking brake

摘要

An apparatus for warning against lack of stroke in an electronic parking brake may include: a tension sensor for sensing the tension of a cable which is provided in an actuator so as to transmit power; a motor for providing power to the actuator; and a controller for controlling whether to operate the motor based on the sensed tension of the cable and a preset target tension, and calculating an operating stroke of the actuator based on an operating time of the motor. The controller may issue a stroke lack warning based on the operating stroke and a preset critical stroke.
