Abstract
A hybrid vehicle driving device is capable of causing a motor-powered travel of a hybrid vehicle in which only an electric motor is used as a drive force source, by driving the electric motor with electric power from an electric storage device while a rotational driving of an internal combustion engine has been stopped. A control device for the hybrid vehicle driving device includes a rotational drive portion that determines whether or not supply of a lubrication oil to at least a portion of the power transmission device by the lubrication oil supply device is necessary based on a travel distance in the motor-powered travel following a stop of the rotational driving of the internal combustion engine, and rotationally drives the internal combustion engine based on determination as to need for the supply of the lubrication oil.
