The present invention relates to technology for efficiently controlling, when heating is requested, a flow rate discharged from an oil heat exchanger according to a heat source of an engine to improve fuel efficiency. The present invention provides a method for controlling a flow control valve, comprising the steps of: calculating an amount of required calorie for heating and an amount of required calorie for oil heat exchange when it is determined that a heater is on while the cooling water temperature is exceeding a flow stop reference temperature and a temperature of the oil to be heat-exchanged with the cooling water is lower than a predetermined temperature; and controlling the flow control valve so as to discharge the cooling water to the heater core side and restrict the discharge of the cooling water to the oil heat exchanger side when it is determined that the amount of required calorie for heating can not be satisfied due to the amount of required calorie for oil heat exchange.
본 발명은 난방 요구시 엔진의 열원에 따라 오일열교환기에 배출되는 유량을 효율적으로 제어하여 연비 향상을 도모하는 기술에 관한 것으로, 본 발명에서는 냉각수온이 유동정지기준온도 초과이고, 냉각수와 열교환되는 오일의 온도가 일정온도 미만인 상태에서, 히터를 온 작동한 것으로 판단한 경우 난방 요구열량과 오일열교환 필요열량을 연산하고; 상기 오일열교환 필요열량으로 인해 난방 요구열량을 충족하지 못하는 것으로 판단시, 히터코어 측에 냉각수를 배출하고 오일열교환기 측에 냉각수의 배출을 제한하도록 유량제어밸브를 제어하는 것을 특징으로 하는 유량제어밸브의 제어방법이 소개된다.
