AUTOMATIC TRANSMISSION AND CONTROL METHOD FOR SAME

摘要

Detect the temperature of oil being supplied to an electrically powered oil pump, and if the oil temperature is either low or high in comparison to normal oil temperature then set a gradient threshold which is less than the gradient threshold for normal oil temperature. Then, detect the gradient of the road surface whereon the vehicle is stopped, and if the detected road surface gradient is greater than the set gradient threshold, prohibit idle-stop.
