ABSTRACT:
A control device for a vehicular drive system including a differential mechanism operable to distribute an output of an engine to a first electric motor and a power transmitting member, and a second electric motor disposed in a power transmitting path between the power transmitting member and a drive wheel of a vehicle. The control device includes a differential-state switching device operable to place the differential mechanism selectively in one of a differential state and a non-differential state, and a switching control device operable to control the differential-state switching device, so as to place the differential mechanism in the differential state when the vehicle is in a motor-drive mode in which at least one of the first and second electric motors is used as a drive power source to drive the vehicle.
