Abstract

본 발명은 차량의 라디에이터를 냉각시키는 쿨링 팬을 구동시킬 경우에 엔진의 아이들 속도를 보정하는 것이다. 본 발명은 라디에이터의 온도가 설정 온도 이상으로 될 경우에 쿨링 팬을 동작시키고, 라디에이터의 온도가 설정 온도 이상으로 되어 쿨링 팬을 동작시킬 경우에 먼저 엔진의 아이들 속도를 보정하여 충분한 전원을 공급할 수 있도록 하는 것으로서 라디에이터에 온도센서(TH)를 설치하여 라디에이터의 온도를 검출하고, 온도센서(TH)가 검출한 라디에이터의 온도를 미리 설정된 온도와 비교하며, 비교결과의 온도가 설정 온도 이상으로 될 경우에 엔진의 아이들 속도를 보정한 후 쿨링 팬을 구동시켜 라디에이터를 냉각시킨다.The present invention corrects the idle speed of the engine when driving a cooling fan that cools the radiator of the vehicle. The present invention operates the cooling fan when the temperature of the radiator is higher than the set temperature, and when the cooling fan is operated because the temperature of the radiator is higher than the set temperature, the idle speed of the engine is first corrected so that sufficient power can be supplied. When the temperature sensor TH is installed on the radiator to detect the temperature of the radiator, the temperature of the radiator detected by the temperature sensor TH is compared with the preset temperature, and when the temperature of the comparison result is equal to or higher than the set temperature. After the engine's idle speed is corrected, the cooling fan is driven to cool the radiator.
