Claims (1)
- (정정) 에어플로우 센서, 크랭크각 센서, 수온센서 및 쓰로틀 위치센서로부터 감지되는 신호를 입력받는 입력단계와 ; 상기 에어플로우 센서 및 크랭크각 센서로부터 입력되는 신호를 이용하여 엔진부하를 연산하는 제 1 단계와 ; 상기 제 1 단계에서 연산된 엔진부하의 변화량이 제 1 기준값 이하인가를 판단하고, 제 1 기준값보다 크다고 판단되면 입력단계로 리턴하는 제 2 단계와 ; 상기 제 2 단계에서 엔진부하의 변화량이 제 1 기준값 이하라고 판단되면, 쓰리틀 밸브의 개도 변동율이 제 2 기준값 이하인지를 판단하고, 제 2 기준값보다 크다고 판단되면 입력단계로 리턴하는 제 3 단계와 ; 상기 제 3 단계에서 쓰로틀 밸브의 개도 변동율이 제 2 기준값 이하라고 판단되면, 엔진회전수의 변동량이 제 3 기준값 이하인지를 판단하고, 제 3 기준값보다 크다고 판단되면 입력단계로 리턴하는 제 4 단계와 ; 상기 제 4 단계에서 엔진회전수의 변동량이 제 3 기준값 이하라고 판단되면, 냉각수 온도가 제 4 기준값 이상인지를 판단하고, 제 4 기준값보다 작다고 판단되면 상기 입력단계로 리턴하는 제 5 단계와 ; 상기 제 5 단계에서 냉각수 온도가 제 4 기준값 이상이라고 판단되면, 상기 엔진회전수가 쓰로틀 밸브의 개도량에 따른 이론 흡기량과 상기 에어플로우 센서에 의해 감지되는 실제 흡기량의 차이가 제 5 기준값 이상인지를 판단하며, 제 5 기준값 보다 작으면 입력단계로 리턴하고, 제 5 기준값 이상이면 오동작신호를 출력하는 제 6 단계를 포함하는 것을 특징으로 하는 VVT의 고장진단방법.
