Abstract
본 발명은 기통 신호의 이상시 엔진제어를 정지시킴으로써 기통 판별신호의 이상으로 인한 엔진 오동작을 방지할 수 있도록 한 차량의 기통식별신호 이상진단 및 제어방법에 관한 것으로, 기통식별신호에 의해 기통을 식별하는 S1단계와, 해당 기통의 제1카운터내지 제4카운터의 값이 정상인가를 판단하는 S2-S5단계와, 상기 S2-S5단계에서 해당기통의 카운터값이 정상이면, 엔진을 제어하여 인젝션, 이그니션등이 수행되게 하는 S6단계와, 상기 S2-S5단게에서 해당기통의 카운터값이 정상이 아니면 사용한 카운트값을 임의의 상수값(Y)으로 변경하고, 다음 TDC에 사용할 카운터에 정상시의 상수값(X)을 설정하는 S7-S10단계로 이루어진다.The present invention relates to a vehicle identification signal abnormality diagnosis and control method for preventing engine malfunction due to an abnormality of the cylinder discrimination signal by stopping the engine control when the cylinder signal is abnormal, wherein the cylinder is identified by the cylinder identification signal. In step S1 and the steps S2-S5 determining whether the value of the first counter to the fourth counter of the cylinder are normal, and if the counter value of the corresponding cylinder is normal in the step S2-S5, the engine is controlled to inject, If the counter value of the cylinder is not normal in step S6 and the ignition is performed, the count value used is changed to an arbitrary constant value (Y) and the constant at the time of the counter to be used for the next TDC. In step S7-S10 of setting a value (X).
