The present invention relates to a GPF heating control method. Specifically, the object of the present invention is to provide the GPF heating control method which can perform efficient heating of a gasoline particle filter (GPF) by linking the operation of an active air flap (AAF) to gasoline particle filter (GPF) heating control by additionally securing a heat source required for GPF regeneration by the operation of the AAF in addition to an increase in exhaust temperature through the torque reserve of an engine. 본 발명은 GPF 히팅 제어 방법에 관한 것으로서, 상세하게는 GPF(Gasoline Particle Filter) 히팅 제어에 AAF(Active Air Flap)의 작동을 연계시켜, 엔진의 토크 리저브(Toque Reserve)를 통한 배기온 상승 외에 GPF 재생에 필요한 열원을 AAF의 작동에 의해 추가 확보하여 GPF의 효율적인 히팅을 수행할 수 있도록 하는 GPF 히팅 제어 방법을 제공하는데 목적이 있다.
