Providing a control device of a vehicle drive device capable of improving vehicle fuel efficiency by adjusting a torque of an electric motor to control an operating point of an engine. A first electric motor MG1, a second electric motor MG2, and a torque converter 16 make up a continuously variable transmission 60 as a whole and an engine operating point control means 70 provides an engine operating point control in which a first electric motor torque T MG1 is adjusted to control an operating point of an engine 12 during an engine running. Therefore, since a continuously variable transmission operation of the continuously variable transmission 60 can be performed by adjusting the first electric motor torque T MG1 (basically, regenerative torque) and the continuously variable transmission operation of the continuously variable transmission 60 enables the operating point of the engine 12 to be controlled without being constrained by a turbine rotation speed Nt, the engine 12 can be driven at an operating point optimal for the fuel efficiency improvement, for example, and the vehicle fuel efficiency can be improved. |
