The present invention relates to an active air flap control method for a vehicle, which comprises: an input step of allowing a controller to receive an input of the amount of individual cooling demands required by a plurality of cooling-required devices mounted on an engine room; a request duty calculating step of allowing the controller to calculate a requirement duty in accordance with the amount of cooling demands of each of the cooling-required devices; a correction duty calculating step of allowing the controller to calculate a correction duty for each of the cooling-required devices by multiplying the requirement duty for each of the cooling-required devices by an external temperature factor in accordance with an external temperature of a vehicle; a final duty selecting duty of allowing the controller to select a maximum value among correction duties of each of the cooling-required devices as a final duty; and a flap driving step of allowing the controller to adjust the opening degree of an active air flap with the selected final duty. According to the present invention, the optimal cooling performance for various cooling requirements is provided.

    본 발명은 컨트롤러가 엔진룸에 탑재된 다수의 냉각 필요 장치들이 요구하는 개별적인 냉각요구량을 입력 받는 입력단계와; 상기 컨트롤러가 상기 각 냉각 필요 장치들의 냉각요구량에 따라 요구듀티를 산출하는 요구듀티산출단계와; 상기 컨트롤러가 상기 각 냉각 필요 장치들에 대한 요구듀티에 차량의 외기온에 따른 외기온팩터를 곱하여, 각 냉각 필요 장치들에 대한 보정듀티를 산출하는 보정듀티산출단계와; 상기 컨트롤러가 상기 각 냉각 필요 장치들의 보정듀티들 중 최대값을 최종듀티로 선정하는 최종듀티선정단계와; 상기 컨트롤러가 상기 선정된 최종듀티로 액티브 에어 플랩의 개도를 조절하는 플랩구동단계를 포함하여 구성된다.
