- 제동되는 바퀴의 회전성향이 측정되고 고정의 위험이 있을 때에 압력감소시간 중에 다수의 연속제어싸이클에서 브레이크압력이 감속되고 이어서 다시 증가되는 차량용 앤티록브레이크시스템의 브레이크압력제어방법에 있어서, 현재 제어싸이클(n)의 압력감소시간(tn ab)이 선행제어싸이클(n-1)의 압력감소시간(tab n-1)에 따른 제1인수와 선행제어싸이클에서 바퀴의 최대재가속도(peadn-1)에 따른 적어도 제2인수의 적으로 계산됨을 특징으로 하는 차량용 앤티록브레이크 시스템의 브레이크압력제어 방법.
- 청구범위 1항에 있어서, 제1인수가 선행제어싸이클의 압력감소시간(tab n-1)임을 특징으로 하는 방법.
- 청구범위 1항 또는 2항에 있어서, 제2인수가 선행제어싸이클(n-1)에서 측정된 바퀴의 예정값(peak-soll)과 최대재가속도(peadn-1)의 지수에 따라 좌우됨을 특징으로 하는 방법.
- 청구범위 1항에 있어서, 현재 제어싸이클(n)의 압력감소시간(tn ab)이 바퀴의 감속과 또는 슬립이 예상 한계 값보다 클 때에 연장됨을 특징으로 하는 방법.
- 청구범위 3항에 있어서, 예정값(peak-soll)이 선행제어싸이클(n-1)에서 바퀴의 속도감소의 함수임을 특징으로 하는 방법.
- 청구범위 1항에 있어서, 압력감소시간(tab) 이후에 브레이크 압력이 현재 제어싸이클(n)에서 일정하게 유지되고 바퀴의 주면속도가 압력감소시간(tab)의 종료로 한계 값까지 감소되었을 경우 브레이크압력감소가 계속됨을 특징으로 하는 방법.
- 청구범위 1항에 있어서, 압력감소시간(tn ab)의 종료전에 제동되는 바퀴가 현재 제어싸이클(n)중에 예정 한계 값보다 크게 재가속되는 즉시 브레이크압력감소가 종료됨을 특징으로 하는 방법.
- 청구범위 1항에 있어서, 선행제어싸이클(n-1)에서 제어편차가 예정비교치보다 작은 경우에 현재제어싸이클(n)의 압력감소시간(tn ab)이 선행제어싸이클(n-1)의 압력감소시간(tab n-1)과 같도록 조절됨을 특징으로 하는 방법.
