Electronic parking brake EPB system and method of controlling the same

摘要

An electronic parking brake system and method for controlling an EPB system are disclosed. An EPB system including EPB actuator operated by a motor includes a motor driver which drives the motor of the EPB actuator; a current detector which detects a current flowing in the motor; and an electronic control unit (ECU) which drives the motor using the motor driver according to an operation mode, calculates an amount of current energy consumed by the motor using the current detected by the current detector while the motor is driving and a detecting time taken to detect the current, compares the calculated amount of current energy and a preset value, and controls an operation of the motor according to a result of the comparison.
