The present invention relates to a method for reducing non-driven spent fuel. According to the present invention, a road gradient, an accelerator position scope (APS), a vehicle speed, and a state of charge (SOC) of a battery are detected as a creep mode control factor. Moreover, a creep entry ranking is sorted by classifying a detection value of a creep condition factor into descent, level, or climb according to the road gradient; small APS, middle APS, or large APS according to APS press amount; low speed, middle speed, or high speed according to moving speed of the vehicle; and small SOC, middle SOC, or large SOC according to SOC. In addition, the creep mode is performed by a controller according to the creep entry ranking, which enhances accuracy of creep mode recognition. Particularly, the creep mode of a hybrid vehicle is controlled with the controller under a variable condition taking into account a rate of change of SOC, APS and the vehicle speed corresponding to the moving speed of the vehicle allowing for the road gradient such that fuel amount according to non-driven spent fuel decreases and aggravation of fuel economy according to SOC defense is relieved by the entry to the creep mode which exactly reflects a driving environment and a vehicle state.

    본 발명의 비 구동 소모연료 저감 방법은 도로 구배, ΔAPS(Accelerator Position Scope), 차속, 배터리 SOC(State of Charge)를 크리프 모드 제어인자로 검출하고, 크리프 조건인자의 검출값을 도로 경사에 따라 강판/평지/등판, APS 눌림량에 따른 소APS/중APS/대APS, 차량 이동속도에 따른 저속/중속/고속, SOC에 따른 소SOC/중SOC/대SOC로 구분하여 크리프 진입순위가 분류되며, 크리프 모드 수행이 크리프 진입순위에 따라 컨트롤러로 수행됨으로써 크리프 모드 인식의 정확도를 높이고, 특히 상기 컨트롤러로 하이브리드 차량의 크리프 모드가 도로구배가 고려된 차량이동속도인 차속과 APS 및 SOC의 변화율을 고려한 가변 조건으로 제어됨으로써 주행환경 및 차량 상태를 정확히 반영된 크리프 모드 진입으로 비 구동 소모연료에 따른 연료량 감소와 더불어 SOC 방어에 따른 연비 악화도 함께 해소되는 특징을 갖는다.
