Abstract

본 발명은 자동차 속도 감지 장치 고장 판정 방법에 관한 것으로서, 엔진이 정상 상태 진입 후 소정시간의 경과 여부를 판단하고, 상기 판단에 따라 소정시간 경과전이면 경과 할 때까지 기다리고 경과후면 엔진 RPM이 소정치 이상인지를 판단하며, 상기 판단에 따라 소정치 이하면 시작 단계로 가고 소정치 이상이면 서지 탱크내의 공기 압력이 소정차 이상이 되는 지를 판단한다.The present invention relates to a vehicle speed detecting device failure determination method, and determines whether a predetermined time has elapsed after the engine enters a steady state, and waits until the predetermined time elapses before the predetermined time elapses according to the determination. It is determined whether or not it is abnormal, and if it is less than the predetermined value according to the determination, it is determined whether the air pressure in the surge tank is greater than or equal to the predetermined difference.

상기 판단에 따라 소정치 이하이면 시작단계로 가고 소정치 이상이면 가속 페달을 밟고 있음에도 불구하고 차속이 소정치 이하인지를 판단하며, 상기 판단에 따라 소정치 이상이면 정상 판정을 하고 소정치 이하이면 카운트 값이 증가하고, 상기 단계후에 카운트값이 소정치 이상인지를 판단해, 소정치 이하면 다시 시작하고 소정치 이상이면 고장 경고등이 점등하는 원리로 되어 있다.If it is less than the predetermined value according to the determination, it is determined whether the vehicle speed is less than or equal to the predetermined value even though the accelerator pedal is depressed if it is more than or equal to the predetermined value. The value increases, and after this step, it is determined whether the count value is greater than or equal to the predetermined value, and if it is less than or equal to the predetermined value, the operation is restarted.
