Zusammenfassung:	Providing a control device of a vehicle drive device capable of suppressing fuel efficiency deterioration in the vehicle drive device including an engine and an electric motor. The fuel cut electric motor drive control means 146 increases the engine rotation speed Ne with the drive force of the electric motor MG and provides the fuel cut electric motor drive control interrupting the fuel supply to the engine 10 at the time of the acceleration operation of the vehicle 6. When the engine rotation speed Ne is increased at the time of vehicle acceleration, fuel efficiency deterioration can often be suppressed by increasing the engine rotation speed Ne by electric motor drive rather than engine drive. This is because the electric storage device 46 is charged if the electric motor MG performs regenerative operation, for example, during deceleration while a vehicle is running. Therefore, if the engine rotation speed is increased, the interruption of the fuel supply to the engine by the fuel cut electric motor drive control can suppress the fuel efficiency deterioration.
