Abstract

본 발명은 안티-록 제어기를 구비한 브레이크 시스템을 위한 제어량으로서의 페달력(pedal force)을 측정하는 방법 및 회로에 관한 것이다. 그 페달력을 측정하기 위해, 안티-록 제어기(anti-lock control)에 의한 제동중에 수압 펌프의 구동 모터(19)는 발전기 작동식으로 전환되고, 발전기 전압(UM)의 크기 및 그 전압의 소멸 양식(fade-out bdhavior)이 평가된다. 수압 펌프는 압력 감소 중에 휘일(wheel) 브레이크로 부터 배출되는 압력 유체를 되돌려 보내거나, 보조 압력을 공급한다. 페달력에 따른 공급 압력은 발전기 전압 및 그 전압의 소멸 양식에 의해 대략적으로 측정될 수 있다.
