Abstract

본 발명은 페달(1)에 의해 작동 가능한 마스터 실린더(2), 전자 제어 유닛(3)에 의해 제어가능하고 차량의 휠 브레이크(7,8)가 직접 연결되고 밸브 조립체(16,17)에 의해 차단 가능한 유로(11,12)를 거쳐 마스터 실린더 (2)에 연결되는 브레이크압 발생기(4,5) 감속 지시를 인지하는 하나 이상의 센서 장치(13,22,23) 및 마스터실린더와 상호 작용하는 하나 이상의 시뮬레이터 챔버(14,15)를 구비한 자동차용 전자 제어식 브레이크 작동 시스템을 개시하고 있다. 그러나 시스템의 작동. 특히 브레이크압 발생기의 동력을 개선하는 한편, 전체 시스템의 반응 시간을 감소시키기 위해, 본 발명은 밸브 시스템이 시간 지연을 두고 전자제어 유닛에 의해 제어될수 있는 솔레노이드 밸브로서 밸브(16,17)의 형태를 취할 것을 제안한다. 브레이크압 발생기(4,5)의 해제 위치에서, 저압 어큐물레이터(51,52)는 브레이크압 발생기(4,5)의 압력 챔버에 연결되고 휠 브레이크(7,8)에 연결 된다.
