According to the present invention, an electro-hydraulic power unit of a hydraulic brake system comprises: a main flow path; a pump transferring oil to the main flow path; a control flow path branched from the main flow path; a proportional decompression valve filling oil pressure of the control flow path, and maintaining output pressure; a first control valve supplying or blocking oil to the proportional decompression valve; a security brake pressure setting valve setting a pressure in a case of security brake; a second control valve supplying or blocking oil to the security brake pressure setting valve; and a mode select valve selecting emergency, common use, or security brake. Therefore, a brake method can be performed in various shapes of initial brake, emergency or common use brake, security brake, wheel taxing brake, brake releasing, or the like.

    본 발명의 유압 제동 시스템용 전기 유압 동력 장치는, 메인유로; 상기 메인유로로 오일을 압송하는 펌프; 상기 메인유로에서 분기된 제어유로; 상기 제어유로의 오일 압력을 충기하며, 출력 압력을 유지해주는 비례감압밸브; 상기 비례감압밸브에 오일을 공급 또는 차단하는 제1제어밸브; 보안제동시의 압력을 설정하는 보안제동압력설정밸브; 상기 보안제동압력설정밸브에 오일을 공급 또는 차단하는 제2제어밸브; 및 비상·상용 또는 보안제동을 선택하는 모드셀렉트밸브;를 포함하는 것을 특징으로 한다. 이에 따라, 초기 제동, 비상·상용 제동, 보안 제동, 차륜활주보호, 제동 완해 등과 같은 다양한 형태로 제동 방법을 제어하게 된다.
