Abstract
이 발명은 맵(MAP;Manifold Absolute Pressure)센서(Sensor)고장시 페일(Fail) 세이프(Safe)제어장치 및 그 제어방법에 관한 것으로서, 유입되는 공기의 양을 감지하는 맵 센서(11)와; 냉각수의 온도를 감지하는 냉각수 온도 센서(WTS;Water Temperature Sensor,12)와; 스로틀(Throttle)밸브의 열린 정도를 감지하는 스로틀 개도 센서(TPS;Throttle Position Sensor, 13)와; 상기한 각 센서(11,12,13)의 출력을 입력받아, 분사될 연료량을 제어하는 엔진 제어부(14)와, 상기한 엔진제어부(14)의 출력에 따라 연료를 분사하는 인젝터(injector,15)를 포함하여 이루어져서, 맵 센서의 고장 원인에 따라 페일 세이프용 맵 값을 적용하여 엔진의 시동성과 운전성, 그리고 연비를 좋게하는 효과를 가진 맵 센서 고장시 페일 세이프 제어장치 및 그 제어방법에 관한 것이다.The present invention relates to a fail safe controller and a control method thereof in case of failure of a map (MAP; Manifold Absolute Pressure) sensor, and a map sensor 11 for sensing an amount of inflowing air; A water temperature sensor (WTS; 12) for detecting a temperature of the coolant; A throttle opening sensor (TPS) 13 for detecting an opening degree of a throttle valve; An engine control unit 14 which receives the output of each of the sensors 11, 12, 13, and controls the amount of fuel to be injected, and an injector 15 that injects fuel according to the output of the engine control unit 14. Fail-safe control device and its control method in case of failure of the map sensor having the effect of improving engine start-up, operation and fuel efficiency by applying the map value for fail-safe according to the cause of the failure of the map sensor. will be.
