전자식 주차 브레이크 시스템 및 그 제어방법이 개시된다. 본 발명의 일 실시예에 따른 전자식 주차 브레이크 시스템은 바퀴에 마련된 디스크 브레이크에 주차 제동력을 제공하는 전자식 주차 브레이크(ELECTRONIC PARKING BRAKE ; EPB) 액추에이터를 포함하는 전자식 주차 브레이크 시스템에 있어서, 각 바퀴의 휠 속도를 감지하는 휠 속도 감지부와, 차량의 종가속도를 감지하는 종가속도 감지부와, 차량의 밀림을 경고하는 경고부 및 차량 정차시 EPB 액추에이터에 의해 디스크 브레이크에 주차 제동력이 제공되는 동안 휠 속도 감지부를 통해 검출된 휠 속도 정보와 종가속도 감지부를 통해 검출된 차량 종가속도의 변화율 정보를 근거로 차량의 밀림 여부를 판단하고, 차량의 밀림이 발생한 것으로 판단되면 차량의 밀림을 경고하도록 경고부를 제어하는 전자제어유닛을 포함한다.

    Disclosed are an electronic parking brake (EPB) system and a control method thereof. The EPB system according to an embodiment of the present invention, which includes an EPB actuator for supplying parking brake force to a disk brake provided on a wheel, comprises: a wheel speed detection unit for detecting the wheel speed of each wheel; a longitudinal acceleration detection unit for detecting the longitudinal acceleration of a vehicle; a warning unit for warning of the backward sliding of the vehicle; and an electronic control unit for determining the backward sliding of the vehicle based on the wheel speed information detected by the wheel speed detection unit and the change rate information of the vehicle longitudinal acceleration detected by the longitudinal acceleration detection unit while the parking brake force is supplied to the disk brake by the EPB actuator when the vehicle stops and controlling the warning unit to warn of the backward sliding of the vehicle when it is determined that the backward sliding of the vehicle has occurred. The EPB system of the present invention can accurately and reliably determine the backward sliding of the vehicle.
