Abstract:
A control apparatus for controlling a vehicle drive apparatus including: (i) a power transmitting member; (ii) a differential mechanism which has a first element connected to an engine, a second element connected to a first electric motor, and a third element connected to a second electric motor and the power transmitting member; (iii) an automatic transmission constituting at least a part of a power transmitting path between the power transmitting member and a drive wheel; and (iv) a differential-state switching device operable to selectively place the differential mechanism in its differential state in which the second and third elements are rotatable at respective different speeds, and in its non-differential state in which the second and third elements are not rotatable at respective different speeds. The control apparatus includes a switching device controller operable to cause the differential-state switching device to place the differential mechanism in the differential state, at least during generation of an electric energy by the first electric motor and/or second electric motor while the power transmitting path is being disconnected. Also disclosed is a vehicle drive system including the above-described control apparatus.
