Abstract
Description
이러한 유형의 자가보정이 항상 이루어지는 것은 아니다. 상기 자가보정은 트랜스듀서 휠이 회전할 때만 실행될 수 있는데, 임계값과 비교될 값이 변화하는 영역이 이러한 경우에만 검출되기 때문이다.
Claims (12)
- 내연기관을 갖는 차량 내의 캠축 센서의 진단을 위한 방법이며,차량의 작동 중 상기 캠축 센서의 출력이 분석되어 출력신호의 최대값이 제1 임계값에 미달되는지, 또는 출력신호의 최소값이 제2 임계값을 초과하는지, 또는 상기 최대값이 상기 제1 임계값에 미달되고 상기 최소값이 상기 제2 임계값을 초과하는지가 결정되며,이에 해당되는 경우, 상기 캠축 센서가 차량의 재시동 시에 부정확한 데이터를 제공할 수도 있다는 것을 제어 장치에 알리는 신호가 제어 장치에 전달되며,이러한 경우, 상기 캠축 센서의 보정이 수행될 때까지 차량의 재시동 시에 상기 캠축 센서의 출력신호는 차량의 작동, 제어, 또는 작동 및 제어를 위해 사용되지 않는 진단 방법.
- 제1항에 있어서, 제1 임계값은 제2 임계값과 동일한 것을 특징으로 하는 진단 방법.
- 삭제
- 삭제
- 제1항에 있어서, 상기 센서의 출력값의 최소값 및 최대값의 학습에 의해 상기 센서의 보정이 수행되는 것을 특징으로 하는 진단 방법.
- 제1항에 있어서, 제어장치 내에서 신호는 비휘발성 메모리에 저장되고, 이로써 내연기관의 시동시 신호가 직접 사용되는 것을 특징으로 하는 진단 방법.
- 삭제
- 제1항에 있어서, 내연기관의 시동은 비상작동 상태에서 상기 센서의 사용 없이 수행되는 것을 특징으로 하는 진단 방법.
- 제1항 또는 제2항에 있어서, 임계값은 상기 센서의 영구 메모리에 저장되는 것을 특징으로 하는 진단 방법.
- 제9항에 있어서, 상기 센서의 보정을 통해서 임계값이 적응되는 것을 특징으로 하는 진단 방법.
- 제1항에 있어서, 신호의 전송이 엔코딩되어 수행되는 것을 특징으로 하는 진단 방법.
- 삭제
