VEHICLE DRIVE DEVICE

A first rotating machine and a second rotating machine are provided. Total 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 higher than requested torque Tr for a vehicle when transition from a first travel mode, in which one of the first rotating machine and the second rotating machine is used as a power source, to a second travel mode, in which the first rotating machine and the second rotating machine are used as the power sources, is made. The torque command value of the rotating machine, which is used as the power source in the first travel mode, during the transition from the first travel mode to the second travel mode may be set higher than the torque command value before beginning of the transition.
