Claims (5)
- 차량의 주제어수단인 전자제어유니트가 차량의 종방향 감가속도를 검출하기 위한 종감가속도 센서의 출력신호에 기초하여 상기 종감가속도 센서의 고장을 검출하는 장치에 있어서,상기 차량의 각 차륜속도를 검출하는 4개의 차륜속도센서;상기 전자제어유니트의 제어신호에 따라 상기 종감가속도센서의 오프셋 에러를 운전자에게 경고하는 고장표시부를 더 포함하여,상기 4개의 차륜속도센서로부터 검출된 각 차륜속도에 기초하여 차체속도를 산출하고, 산출된 차체속도가 일정속도 이상이고 상기 종감가속도센서로부터 검출된 종감가속도의 절대치가 미리 설정된 값 이상인 상태를 일정시간 이상 지속하는 경우 상기 종감가속도센서를 오프셋 에러로 판단하는 것을 특징으로 하는 차량의 종감가속도센서의 고장검출장치.
