Abstract
When the change speed is instructed, without changing value of a suppressing vibration flag set to value 1 as initial value, a fast fill as the preparation of a brake to be engaged when the change speed is executed and low pressure standby of hydraulic pressure to set the brake in a half-engaged state. Then the suppressing vibration flag is set to value 0 when a predetermined time passed since the change speed is instructed, a sum of a drive torque required for driving and a suppressing vibration torque, which is in the same direction as suppressing rotational fluctuation of a drive shaft, is output from a motor when the suppressing vibration flag is set to value 1.
