Abstract

목적
앤티 록크형 액압 브레이크 장치에 있어서 차량 속도를 정확히 추정 가능하게 한다.
구성
차륜속도 기준값 작성 수단(132)이 작성한 차륜속도 기준값(Vsn)과 차륜속도·차륜속도 변화량 연산 수단(120)이 연산한 차륜속도(Vw)에 의거하여 차륜속도 편차 작성 수단(122)이 차륜속도 편차(Hersa)를 작성한다. 이 편차에 의거하여 증·감압시기 결정수단(136)이 증·감압의 시기를 결정하고, 이것에 따라 ABS 가동기(78)가 브레이크압을 증가시킨다. 좌우 후륜(RL,RR)에 대해서는 선택 제어가 행해지며, 차륜속도(Vw)가 큰 후륜의 감압은 작은 후륜의 감압보다 약간 길게 행해져서 브레이크압이 의도적으로 낮게 된다. 그 결과, 차륜속도(Vw)가 큰 후륜의 차륜속도가 더욱 차량속도에 가깝게 되어서, 차량속도가 정확히 추정될 수가 있으므로 앤티 록크 제어의 정도가 향상된다.
