Description
Claims (3)
- 차륜속도에 따라 산출된 슬립율을 이용하여 ABS 제어모드를 수행하는 ABS 제어방법에 있어서,마스터 실린더의 압력을 검출하는 단계;ABS 제어시점에서 상기 검출된 마스터 실린더의 압력으로부터 각 차륜의 초기휠압력을 산출하는 단계;상기 초기휠압력과 미리 설정된 감압율 및 증압율을 이용하여 ABS의 각 제어모드에서의 각 차륜의 휠압력을 산출하는 단계;상기 산출된 휠압력과 상기 슬립율에 따라 노면상태를 인식하는 단계;상기 인식된 노면상태에 따라 ABS 제어를 수행하는 단계를 구비한 것을 특징으로 하는 압력센서를 이용한 ABS 차량의 노면판단방법.
- 제 1항에 있어서,상기 노면상태 인식단계는 상기 산출된 휠압력과 상기 휠압력을 산출하는 시점의 슬립율에 해당하는 미리 설정된 휠압력을 비교하는 단계;상기 비교결과에 따라 노면상태를 인식하는 단계를 포함하는 것을 특징으로 하는 압력센서를 이용한 ABS 차량의 노면판단방법.
- 제 2항에 있어서,상기 비교결과 상기 산출된 휠압력이 미리 설정된 휠압력보다 높은 경우 현재 주행중인 노면을 고마찰노면으로 판단하고, 상기 산출된 휠압력이 미리 설정된 휠압력보다 낮은 경우 저마찰노면으로 판단하는 것을 특징으로 하는 압력센서를 이용한 ABS 차량의 노면판단방법.
