Claims (6)
- 운행되는 차량의 상태를 검출하는 차량 상태 검출수단과, 브레이크 오일의 압력을 조절하는 구동수단으로 이루어지는 ABS 제어장치에 있어서, 브레이크 클리퍼부분등에서 발생하는 응력을 검출하는 응력 검출수단;차량 상태 검출수단과 응력 검출수단에서 인가되는 신호에 따라 브레이크 부품에서 최대의 응력이 발생하도록 브레이크 오일의 압력을 조절하기 위한 전반적인 동작을 제어하는 제어수단으로 이루어지는 것을 특징으로 하는 ABS 제어장치.
- 청구항 1에 있어서, 응력 검출수단은 브레이크 캘리퍼의 임의의 위치에 설치되며, 캘리퍼의 응력변화에 따라 소정의 전기적 신호를 출력하는 스트레이 게이지로 이루어지는 것을 특징으로 하는 ABS 제어장치.
- 제동시 검출되는 운행정보로 부터 ABS 제어영역을 판단하는 단계;ABS 제어영역으로 판단되면 응력 검출부에서 인가되는 신호를 분석하여 응력변화율을 검출하고, 검출되는 응력변화율에 따라 최대 마찰력을 산출하는 단계;검출되는 응력변화율과 최대 마찰력을 비교하여 제동시 브레이크 부품에서 최대의 응력이 발생하도록 브레이크 오일의 압력을 조절하는 단계로 이루어지는 것을 특징으로 하는 ABS 제어방법.
- 청구항 3에 있어서, 차량상태 검출부에서 인가되는 신호를 분석하여 원주 감속도, 가속도, 제동슬립, 기준속도 그리고 차량 감속도를 검출하는 단계를 더 포함하는 것을 특징으로 하는 ABS 제어방법.
- 청구항3에 있어서, 응력변화율이 일정값 이상 검출되면 브레이크 오일의 압력을 가압하며, 응력변화율이 일정값 이하로 검출되면 브레이크 오일의 압력을 감압하는 단계를 더 포함하는 것을 특징으로 하는 ABS 제어방법.
- 청구항 5에 있어서, 일정값은 최대 마찰토크를 나타내는 응력변화율이 제로인 구간으로 설정하는 단계를 더 포함하는 것을 특징으로 하는 ABS 제어방법,
