Abstract

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.

Description

technical field [0001] The present invention relates to an electronic parking brake system and its control method, more specifically, to an electronic parking brake system and its control method for controlling the electronic parking brake to perform a braking operation or to release the braking operation . Background technique [0002] In recent years, an Electronic Parking Brake (EPB) system that electronically controls actuation of a parking brake is used, which is mounted on a general disc brake and performs a function of a parking brake. [0003] Such an electronic parking brake system is composed of an EPB actuator (Actuator) provided with a motor generating braking force, and an electronic control unit for driving the EPB actuator. [0004] The electronic control unit drives the EPB actuator to make the parking brake perform a parking operation (apply) or release (release) the parking operation. [0005] The protection concept of the previous EPB actuator is to use ...
