Abstract

본 발명은 엔진의 아이들 스피드 액추에이터 구동 장치에 이상이 발생 되었을 경우에 ISA 구동 장치의 동작 상태를 림프 홈 모드로 전환시킬 필요가 있기 때문에, 더블 코일 타입 ISA 구동 장치에 고장 발생시 각 코일에 발생되는 이상 상태를 상호 조합함으로써 도출된 그 결과치에 따라 림프 홈 모드로 전환되면서 ECU가 ISA 구동 장치의 이상 상태를 고장 상태로 인식하여 엔진을 정지시키지 않고 맵핑된 상태로 ISA를 작동시키도록 구성되어, 엔진이 정지되기 이전에 림프 홈 모드로 전환되고 ISA 구동 장치 내의 가동 가능한 부분을 제어하여 ISA를 구동시키면서 정비소로 이동할 수 있게 함으로써 이동 중의 엔진 출력이 그대로 유지되게 할 수 있는 아이들 스피드 액추에이터 구동 장치 진단에 따른 림프 홈 기능 제어 방법에 관한 것이다.Since the present invention needs to switch the operating state of the ISA drive device to the limp home mode when an error occurs in the idle speed actuator drive device of the engine, an abnormality generated in each coil when a failure occurs in the double coil type ISA drive device. According to the result derived from the combination of states, the ECU is configured to operate the ISA in the mapped state without stopping the engine by switching to the limp home mode as the ECU recognizes the abnormal state of the ISA drive unit. Lymph at diagnosis of an idle speed actuator drive that can be switched to limp home mode before it is stopped and control the flexible portion within the ISA drive to allow the engine to move while the ISA is running so that engine power is maintained on the move. Home function control method.
