Description
Claims (2)
- 차량의 각 차륜으로부터 차륜의 회전속력을 구하고, 이로부터 차량의 현재 슬립률(λ)과 차륜가속도(A)를 연산하며, 이를 지속적으로 관찰하여 슬립률이 일정범위에 유지되도록 차륜의 제동력을 제어하는 제동력 제어시스템의 제어방법에 있어서, 증압시간(Tr)과, 차륜의 현재가속도가 기준가속도의 범위내에 머무르고 있는 기간(Ta)을 측정하고, 상기 슬립률(λ)이 기준슬립률(λK1) 보다 작으며 차륜의 가속도(A)는 기준가속도(AK1) 보다 크거나, 이전 제어사이클에서의 증압기간(Tpr) 보다 현재의 증압기간(Tr)이 기준값(TK1) 이상으로 큰 경우로서 현재의 슬립률(λ)이 기준슬립률(λK2)보다 작거나, 증압기간 중 차륜의 현재가속도(A)가 기준가속도(Ak3에서 Ak2)의 범위내에서 머무르고 있는 기간(Ta)이 기준기간(TK2)보다 큰 경우로서 현재의 슬립률(λ)이 기준슬립률(λK2)보다 작으면, 저마찰계수 노면에서 고마찰계수 노면의 점프한 것으로 판단하는 것을 특징으로 하는 제동력 제어시스템의 노면 점프 판단방법.
- 제1항에 있어서, 상기 차륜의 현재가속도(A)가 기준가속도의 범위(Ak3에서 Ak2) 내에서 머무르고 있는 기간(Ta)을 측정하는 방식은 기준가속도 범위내(Ak3에서 Ak2)에서의 증압횟수(N)를 세는 방식을 사용하고, 차륜의 현재가속도(A)가 기준가속도의 범위내에서 머무르고 있는 기간(Ta)과의 비교기준이 되는 기준기간(Tk2)은 기준증압횟수(Nk)인 것을 특징으로 하는 제동력 제어시스템의 노면 점프 판단방법.
