Gangwechselsteuereinheit für ein stufenlos verstellbares Getriebe

摘要

In a continuously variable transmission which varies a speed change ratio based on a target speed change ratio which has been set according to a running condition of a vehicle, a sensor is provided for detecting the temperature of the continuously variable transmission. A shift amount of the speed change ratio due to a thermal expansion difference of parts of the continuously variable transmission is prevented by correcting the target speed change ratio based on the temperature detected by the sensor.
