Claims (13)
- 신호 특히, 배기 가스 후처리 시스템의 입구 및 출구에서의 압력 및/또는 입구와 출구 사이의 압력 차이를 나타내는 압력 신호의 감시 방법에 있어서,센서 신호에 발생된 진동에 따라 그리고/또는 압력 신호 및 배기 가스 질량 유동을 나타내는 배기 가스 질량 유동 변수의 시간적 상태에 따라 에러가 검출되는 것을 특징으로 하는 방법.
- 제1항에 있어서, 신호의 진동 진폭을 나타내는 변수가 허용 가능한 범위 외부에 존재할 때 에러가 검출되는 것을 특징으로 하는 방법.
- 제2항에 있어서, 신호의 진동 진폭을 나타내는 변수가 임계값 보다 작을 때 에러가 검출되는 것을 특징으로 하는 방법.
- 제3항에 있어서, 임계값은 엔진 및/또는 배기 가스 후처리 시스템의 작동 상태에 따라 사전 설정될 수 있는 것을 특징으로 하는 방법.
- 제4항에 있어서, 임계값은 회전수 및/또는 분사 연료량에 따라 사전 설정될 수 있는 것을 특징으로 하는 방법.
- 제1항 내지 제5항 중 어느 한 항에 있어서, 변수는 신호와 평균 신호 사이의 차이에 따라 결정되는 것을 특징으로 하는 방법.
- 제1항 내지 제6항 중 어느 한 항에 있어서, 신호와 평균 신호 사이의 차이의 평균값이 변수로서 사용되는 것을 특징으로 하는 방법.
- 제1항 내지 제7항 중 어느 한 항에 있어서, 압력 신호의 변화율 및 배기 가스 질량 유동을 나타내는 배기 가스 질량 유동 변수의 변화율이 부적합하면, 에러가 검출되는 것을 특징으로 하는 방법.
- 제8항에 있어서, 배기 가스 질량 유동 변수가 변하면, 특히 적게 증가하면, 압력 변수가 너무 적게 변할 때, 특히 임계값 보다 적게 증가될 때 에러가 검출되는 것을 특징으로 하는 방법.
- 제8항 또는 제9항에 있어서, 배기 가스 질량 유동 변수가 변하면, 특히 감소하면, 압력 변수가 너무 적게 변할 때, 특히 임계값 보다 적게 감소될 때 에러가 검출되는 것을 특징으로 하는 방법.
- 제8항 내지 제10항 중 어느 한 항에 있어서, 제1 기간 동안 너무 작은 압력 변수가 존재할 때, 에러가 검출되는 것을 특징으로 하는 방법.
- 제8항 또는 제9항에 있어서, 제2 기간에 대해 배기 가스 질량 유동 변수가 크게 감소되면 너무 작은 압력 변수가 존재할 때, 에러가 검출되는 것을 특징으로 하는 방법.
- 신호 특히, 배기 가스 후처리 시스템의 입구 및 출구에서의 압력 및/또는 입구와 출구 사이의 압력 차이를 나타내는 압력 신호의 감시 장치에 있어서,센서 신호에 발생된 진동에 따라 그리고/또는 압력 변수 및 배기 가스 질량 유동을 나타내는 배기 가스 질량 유동 변수의 시간적 상태에 따라 에러가 검출되는 것을 특징으로 하는 장치.
