Abstract
A continuously variable transmissionchanges a speed-change ratio γ so that an actual rotation speed Nof an input shaftcoincides with a target rotation speed N* set based on a target output P*. A target output calculating portioncalculates a first target drive force related value P* based on both an acceleration required amount Acc and a load of an auxiliary machine A, calculates a second target drive force related value P* based on the acceleration required amount without considering the auxiliary machine load, and sets the second drive force related value as the drive force related value P* upon a vehicle regular running. Even when the auxiliary machine load fluctuates in the vehicle regular running the target output does not fluctuate, and prevention of fluctuation of the target output rotation speed increases the drivability in the vehicle regular running.
