Abstract: When throttle valve opening degree is larger than predetermined throttle valve opening degree Y in the case where a decision on shift to gear stage at which maximum load is applied to predetermined rotary member of automatic transmission is made, the gear stage is not formed. Therefore, large load is restrained from being applied to the predetermined rotary member of the automatic transmission. Besides, gear stage that is lower in vehicle speed than the gear stage by one stage or gear stage that is higher in vehicle speed than the gear stage by one stage is formed depending on whether acceleration requirement is large or small. Therefore, driving torque corresponding to the acceleration requirement is likely to be obtained. In consequence, the load applied to the predetermined rotary member of the automatic transmission can be reduced, and feeling of strangeness can be restrained from being caused by the driving torque.
