Abstract
본 발명은 배기가스 재순환(EGR : Exhaust Gas Recirculation) 제어 밸브의 정상 작동 판단 방법에 관한 것으로, 특히 EGR 제어 밸브내의 압력을 부스트(Boost) 센서를 이용하여 검출하여 이를 기준 EGR 밸브 제어 값과 비교하여 EGR 제어 밸브의 정상 작동 여부를 판단하는 EGR 제어 밸브의 정상 작동 판단 방법에 관한 것이다.The present invention relates to a method for determining normal operation of an exhaust gas recirculation (EGR) control valve, and more particularly, to a method of detecting a normal operation of an exhaust gas recirculation (EGR) control valve by detecting a pressure in an EGR control valve using a boost sensor, The present invention relates to a normal operating determination method for an EGR control valve that determines whether or not the EGR control valve is normally operated.
본 발명은 EGR 제어 밸브 정상 작동 판단 방법은 EGR 제어 밸브가 작동중일 때 부스트 센서에 의해 검출된 EGR 제어 밸브의 압력신호값과 기준값을 비교하는 단계와, 상기 비교 결과 압력신호값이 기준값과 같거나 클 경우 상기 EGR 제어 밸브가 정상인 것으로 판단하고, 상기와 반대인 경우는 상기 EGR 제어 밸브가 고장인 것으로 판단하는 단계와, 상기 판단 결과를 메모리에 기억시킨 후 상기 기억된 값을 점검함에 의해 EGR 제어 밸브의 정상 동작 여부를 진단하는 단계로 구성되는 것을 특징으로 한다.A method of determining normal operation of an EGR control valve includes comparing a pressure signal value of an EGR control valve detected by a boost sensor with a reference value when the EGR control valve is in operation and comparing the pressure signal value with a reference value Determining that the EGR control valve is normal if it is determined that the EGR control valve is normal, and determining that the EGR control valve is malfunctioning if it is determined that the EGR control valve is normal; and storing the determination result in the memory, And diagnosing whether the valve operates normally or not.
