Abstract
A transmission controller determines whether or not an input rotation speed of a sub-transmission mechanism is stagnant and executes a feedback control by adding a rotation speed change rate feedback correction amount caused by a difference between a target input rotation speed change rate and an actual input rotation speed change rate of the sub-transmission mechanism to a rotation speed feedback correction amount if the input rotation speed is determined to be stagnant.
