Abstract
The present invention provides a CVT including a transmission mechanism and a planetary gear mechanism which includes a plurality of rotation elements. The transmission mechanism can differentially operate in a predetermined operation mode. The CVT includes a vehicle speed specifying unit for specifying a vehicle speed based on a rotation speed of a rotation member. The unit specifies the vehicle speed from the rotation speed when the rotation speed exceeds a threshold, and specifies the vehicle speed based on a target driving force, a running resistance and a weight of the vehicle when the rotation speed is not more than the threshold.
