The present invention is provided with a first rotating machine and a second rotating machine, wherein the sum torque of a torque command value (Tt1) of the first rotating machine and a torque command value (Tt2) of the second rotating machine is set larger than a required torque (Tr) for a vehicle when transitioning from a first travel mode in which one of the first rotating machine and the second rotating machine is used as the power source to a second travel mode in which the first rotating machine and the second rotating machine are used as the power source. The torque command value when transitioning from the first travel mode to the second travel mode for the rotating machine used as the power source in the first travel mode may be set larger than the torque command value prior to starting said mode transition.
