The present invention relates to a method for controlling engine torque and transmission shift in the winter when the weather is cold. The present invention provides a method for controlling the engine torque and transmission shift in the winter season, comprising: a vehicle low temperature condition determining step; a transmission shift low temperature determining step; a low temperature region control logic actuating step; and a transmission shift low temperature condition feedback step, wherein an engine torque map and transmission shift map are changed downwards at conditions of low temperature of engine intake air and low temperature of transmission shift oil in the winter. The present invention provides a method for controlling the engine torque and transmission shift in the winter, in which the engine torque is intentionally downward using values of external intake air temperature and transmission shift oil temperature when the temperature in a corresponding region is low, and a new transmission control map is configured to add a new driving mode that transmission pattern optimization is possible according thereto, thereby ensuring soft transmission sense and operability and enhancing real mileage.

    본 발명은 날씨가 추운 동절기의 차량 운전시 변속감, 운전성 및 연비를 향상시키는 동절기 엔진토크 및 변속 제어방법에 관한 것으로, 본 발명에 따른 동절기 엔진토크 및 변속 제어방법은 차량 저온조건 판단 단계, 변속기 저온조건 판단 단계, 저온영역 제어로직 작동 단계, 및 변속기 저온조건 피드백 단계를 포함하며, 동절기 엔진 저흡기온 및 변속기 저유온 조건시 엔진토크맵 및 변속패턴을 하향 변동시키는 것을 특징으로 한다. 본 발명에 따른 동절기 엔진토크 및 변속 제어방법은 외부 흡기온 및 변속기 유온값을 이용하여 해당 지역의 기온이 낮을 시 엔진토크를 의도적으로 하향하고 그에 따른 변속패턴 최적화가 가능한 신규 주행모드를 추가하도록 신규 변속제어 맵을 구성하여 부드러운 변속감 및 운전성을 확보하고, 실연비를 향상시키는 효과를 갖는다.
