The present invention provides an electrohydraulic brake which safely brakes a vehicle. According to an embodiment of the present invention, the electrohydraulic brake comprises: a main brake to generate braking power in a front wheel and a rear wheel of a vehicle; an electronic parking brake (EPB) to generate braking power in one between the front wheel and the rear wheel; the main control unit controlling the operation of the main brake; and a redundancy control unit (RCU) controlling the operation of the electronic parking brake. The redundancy control unit slip-controls the vehicle by using the electronic parking brake based on a signal from a wheel speed sensor if a fault is determined to have occurred in a braking function of the main control unit.

    본 개시의 일 실시예에 의하면, 차량의 전륜 및 후륜에 제동력을 발생시키기 위한 주제동장치(main brake); 전륜 및 후륜 중 어느 하나에 제동력을 발생시키기 위한 전동식 주차브레이크(EPB: electronic parking brake); 주제동장치의 작동을 제어하는 메인제어부(main control unit); 및 전동식 주차브레이크의 작동을 제어하는 백업제어부(RCU: redundancy control unit)를 포함하되, 백업제어부는 메인제어부의 제동 기능에 고장이 발생하였다고 판단한 경우, 휠속센서(wheel speed sensor)로부터의 신호에 기초하여 전동식 주차브레이크를 이용하여 차량을 슬립제어하는 것을 포함하는 것을 특징으로 하는 전자식 유압 브레이크 장치를 제공한다.
