Claims (4)
- 4개 바퀴의 제동력을 각각 조절하는 제동압조절기와,선회제동 중에 차량거동이 오버스티어이면, 전륜 선회외측 바퀴의 제동력을 증가시킴과 함께 나머지 바퀴 중 적어도 하나의 바퀴의 제동력을 감소시키고, 언더스티어이면, 후륜 선회내측 바퀴의 제동력을 증가시킴과 함께 나머지 바퀴 중 적어도 하나의 바퀴의 제동력을 감소시키도록 상기 제동압조절기를 제어하는 제어부를 포함하는 차량 자세 제어장치.
- 선회제동 중에 차량거동이 오버스티어인지 언더스티어인지를 판단하고,상기 판단결과에 따라 제동 중인 바퀴 중 제동력을 추가할 바퀴를 결정하고,상기 결정된 바퀴의 제동력을 증가시키고,상기 결정된 바퀴의 제동력을 증가시킴과 함께 나머지 바퀴 중 적어도 하나의 바퀴의 제동력을 감소시키는 것을 특징으로 하는 차량 자세 제어장치의 제어방법.
- 제2항에 있어서, 상기 차량거동이 오버스티어인 경우, 전륜 선회외측 바퀴의 제동력을 증가시키고, 전륜 선회내측 바퀴 또는 전후륜 선회내측 바퀴의 제동력을 감소시키는 것을 특징으로 하는 차량 자세 제어장치의 제어방법.
- 제2항에 있어서, 상기 차량거동이 언더스티어인 경우, 후륜 선회내측 바퀴의 제동력을 증가시키고, 전륜 선회외측 바퀴 또는 전후륜 선회외측 바퀴의 제동력을 감소시키는 것을 특징으로 하는 차량 자세 제어장치의 제어방법.
