The present invention relates to an active purge pump control method during high-altitude driving, including the steps of: determining an altitude of a place where a vehicle is placed based on atmospheric pressure; and determining whether the altitude at which the vehicle is placed is less than a critical altitude based on the atmospheric pressure. The active purge pump control method during high-altitude driving prevents combustion instability and misfire by controlling the purging amount of boil-off gas in consideration of the altitude estimated based on the atmospheric pressure.

    본 발명은 고지 주행중 액티브 퍼지 펌프 제어 방법에 관한 것으로, 대기압을 근거로 자동차가 위치된 장소의 고도를 판단하는 단계와, 대기압을 근거로 자동차가 위치된 고도가 임계고도 미만인지 판단하는 단계를 포함하며, 대기압을 근거로 추정된 고도를 감안해 증발가스 퍼징량을 제어하므로, 연소불안정 및 실화 발생이 방지되는 효과가 있는, 고지 주행중 액티브 퍼지 펌프 제어 방법을 제공한다.
