Abstract
It is provided a control device of a vehicle drive device having an electric motor connected via an inverter to an electric-motor power source, an inverter smoothing capacitor connected to the inverter of the electric-motor power source side thereof, and a transmission making up a portion of a power transmission path between the electric motor and drive wheels, the control device being configured to make an output torque of the electric motor smaller as the rotation speed of the electric motor being higher, and to make a gradient of an output torque reduced amount of the electric motor larger as the rotation speed of the electric motor being higher if a rotation speed of the electric motor rises at the time of upshift of the transmission higher than a rotation speed before the shift.
