When temperature increase promotion processing (for example, prohibiting lockup application and prohibiting shifts to a high gear position) is started while an initial value of an ATF temperature is in a low temperature region, an ATCU determines whether to terminate the temperature increase promotion processing on the basis of a current ATF temperature, and when the temperature increase promotion processing is started while the initial value of the ATF temperature is in an extremely low temperature region, the ATCU determines whether to terminate the temperature increase promotion processing on the basis of a duration of the temperature increase promotion processing. When the temperature increase promotion processing is determined to be complete, the ATCU terminates the temperature increase promotion processing.
