Abstract

본 발명은 동작상태가 자기진단되는 자동차의 ECS 장치에 관한 것으로서 즉, 종래의 ECS 유니트는 점화전원으로부터 마이콤이 동작할때 동작상태 신호만을 출력하게 됨에 따라 기능의 정상적인 수행상태와 실패상태를 구별하여 확인할 수 없는 문제점이 있었다.The present invention relates to an ECS device of a vehicle in which an operating state is self-diagnosed. That is, a conventional ECS unit outputs only an operating state signal when a microcomputer operates from an ignition power source to distinguish between a normal execution state and a failure state of a function. There was a problem that could not be confirmed.

각종 센서의 신호와 스위치의 신호를 입력 받는 ECS 유니트(10)가 최초 점화전원(20)으로 부터 전원을 공급 받게되면 ECS 인디케이트(40)는 소등상태를 유지하게 되는 전원 공급에 실패하게 되면 마이콤(30)에서 트랜지스터(TR)로 높은 전압의 전류를 출력하여 ECS 인디케이트(40)가 점등될 수 있도록 설치되며, 자기 진단시에는 마이콤(30)이 높은 전압과 낮은 전압을 번갈아가며 출력하여 ECS 인디케이트(40)를 초기 3초동안 점멸한 후 소등될 수 있도록 구성된다.When the ECS unit 10 receiving the signals of various sensors and the signal of the switch is supplied with power from the initial ignition power source 20, the ECS indicator 40 fails to supply the power to keep the light out state. A high voltage current is output from the transistor 30 to the transistor TR so that the ECS indicator 40 can be turned on. During self-diagnosis, the microcomputer 30 alternately outputs a high voltage and a low voltage to output the ECS. The indicator 40 is configured to be turned off after flashing for an initial 3 seconds.
