Abstract
본 발명은 차량용 전자 제어 유니트의 수온 조절기 고장 판정방법을 개시한다. 개시된 본 발명은, 냉각수온을 감지하는 단계; 엔진이 기동되었는지를 판별하는 단계; 기동되었으면, 일정시간으로 설정된 타이머를 작동시키는 단계; 시동 후, 냉각수온의 변화량을 측정하는 단계; 냉각수온의 변화량이 수온 조절기가 개방되도록 설정된 온도와 비교하는 단계; 설정 온도가 냉각수온의 변화량보다 높으면, 타이머에 의해 설정된 시간이 경과되었는지를 판별하는 단계; 및 설정된 시간이 경과되었으면, 수온 조절기를 고장으로 판정하는 단계를 포함하는 것을 특징으로 한다.The present invention discloses a method for determining the fault of a water temperature controller of an electronic control unit for a vehicle. The disclosed invention comprises: sensing cooling water on; Determining whether the engine has been started; Activating a timer set to a predetermined time; Measuring a change amount of the cooling water temperature after startup; Comparing the change amount of the coolant temperature with the set temperature such that the water temperature controller is opened; Determining whether a time set by the timer has elapsed if the set temperature is higher than the change amount of the cooling water ON; And determining that the water temperature controller has failed if the set time has elapsed.
