Abstract

저온시 자동 변속차량이 잦은 변속으로 느끼는 변속감의 저하와 촉매컨버터의 기능저하를 향상시키기 위하여, 스로틀 개도 및 유온과 엔진회전수, 인히비터 스위치 등의 신호를 입력받는 트랜스밋션 제어 유닛에 의해 솔레노이드 밸브가 온/오프되어 유압제어장치의 마찰요소들을 제어하는 자동 변속차량의 변속제어 방법에 있어서, 유온이 설정치보다 낮은 저온 주행시에 스로틀 개도 및 엔진 회전수가 설정치보다 낮으면 설정치 이하에서는 차속에 의해서만 변속이 이루어지는 것을 특징으로 하는 자동 변속차량의 저온시 변속제어 방법.Solenoid valve by transmission control unit that receives signals such as throttle opening degree, oil temperature, engine speed, inhibitor switch, etc. In a shift control method of an automatic transmission vehicle that is turned on / off to control friction elements of a hydraulic control device, when the throttle opening degree and the engine speed are lower than the set value at low temperature when the oil temperature is lower than the set value, the shift is made only by the vehicle speed below the set value. A shift control method at low temperature of the automatic transmission vehicle, characterized in that made.
