A vehicle drive device () is disclosed that includes a shift detent mechanism (); an actuator () that generates drive power for allowing the shift detent mechanism to operate; a sensor () that generates sensor information indicating an amount of operation of the shift detent mechanism; a control part () that controls the actuator; and a clutch () that is synchronized with operation of the shift detent mechanism, and when the control part changes a state of the clutch, the control part performs feedback control of the actuator based on a relationship between a target value for an amount of operation of the shift detent mechanism and the sensor information, and before completing the change in the state of the clutch, the feedback control ends and operation of the actuator stops.

Vehicle drive device and control device

A control device performs upshifting in a state in which an operating point of a rotating electrical machine for outputting requirement-based torque at wheel-based rotational speed falls within an operable range of the rotating electrical machine both before and after shifting a shift speed by the upshifting, and in which before shifting the shift speed, output torque from the rotating electrical machine is less than or equal to determination torque (T), the wheel-based rotational speed being rotational speed of the rotating electrical machine based on rotational speed (V) of a wheel, the requirement-based torque being output torque from the rotating electrical machine based on required wheel transmission torque, and the determination torque (T) being torque obtained by subtracting an amount of increased torque (&#x394;Tmg) resulting from torque increase control from maximum torque (Tmax) that can be outputted from the rotating electrical machine at the wheel-based rotational speed.
