Abstract: When a MODE selector SW is manipulated while CVT automatic shifting mode is selected, the shifting mode is switched to STEP-AT automatic shifting mode. Then, when the shift lever of a shifting device is manipulated by the driver while the CVT automatic shifting mode is selected as the shifting mode of a CVT, the then-set automatic shifting control mode for the CVT is maintained whereas the shifting mode of the CVT is switched to sport mode. When the sport mode being selected as the shifting mode of the CVT is canceled, the shifting mode of the CVT is switched to the mode selected before the switchover to the sport mode, that is, the maintained automatic shifting control mode, unless the MODE selector SW is manipulated during execution of the sport mode.
