One embodiment of the present disclosure provides an electronic hydraulic brake. The electronic hydraulic brake comprises: a plurality of wheel brakes for supplying braking force to the wheels of a vehicle; a reservoir for storing brake oil; a master cylinder connected to the reservoir and linked to a main brake motor to form brake oil pressure; a first controller configured to control the main brake motor according to braking input; a hydraulic control unit comprising a pump configured to form brake oil pressure in conjunction with an auxiliary brake motor and a hydraulic block configured to selectively transmit the brake oil pressure generated in the master cylinder or pump to the plurality of wheel brakes; and a second controller configured to control the auxiliary brake motor when the master cylinder or first controller has a malfunction. The hydraulic control unit is provided with one or more auxiliary flow paths that directly transfer brake oil from the reservoir to the pump. The hydraulic block has a first surface on which a plurality of ports to which flow paths are connected is located and a second surface on which the auxiliary brake motor is attached, and one or more surfaces of the hydraulic block and the master cylinder are coupled. Accordingly, cost savings can be achieved by simplifying a brake piping layout and reducing parts.

    본 개시의 일 실시예에 의하면, 차량의 휠에 제동력을 공급하는 복수의 휠브레이크(wheel brake); 브레이크오일(brake oil)을 저장하는 리저버(reservoir); 리저버와 연결되고 주제동모터(main brake motor)에 연동되어 브레이크오일의 압력을 형성하는 마스터실린더(master cylinder); 제동입력에 따라 주제동모터를 제어하도록 구성된 제1 제어기(first controller); 보조제동모터(auxiliary brake motor)에 연동하여 브레이크오일의 압력을 형성하도록 구성된 펌프(pump) 및 마스터실린더 또는 펌프에서 형성된 브레이크오일의 압력을 복수의 휠브레이크에 선택적으로 전달하도록 구성된 유압블록(hydraulic block)을 구비하는 유압제어부(hydraulic control unit); 및 마스터실린더 또는 제1 제어기가 기능 이상이 있는 경우 보조제동모터를 제어하도록 구성된 제2 제어기(second controller)를 포함하되, 유압제어부는 리저버로부터 상기 펌프로 브레이크오일을 직접 전달하는 하나 이상의 보조유로(auxiliary flow path)를 구비하고, 유압블록은 유로가 연결되는 복수개의 포트(port)가 위치하는 제1 면 및 보조제동모터가 부착되는 제2 면을 구비하고, 유압블록의 하나 이상의 면과 상기 마스터실린더가 결합하는 전자식 유압 브레이크를 제공한다.
