Abstract:
A speed change ECU for a CVT sets a target input rotational speed Nin* such that the speed ratio of the CVT is varied stepwise a plurality of times consecutively to the downshift side in response to an operation to depress a brake pedal by a driver, and sets the target input rotational speed Nin* such that an amount of increase S(1), S(2), . . . in input rotational speed along with a downshift becomes smaller as the number of times of execution of downshifts is increased while downshifts in which the speed ratio is varied stepwise are executed consecutively.
