| 摘要 |
A control device for a vehicular drive system including (a) a differential mechanism operable to distribute an output of an engine to a first electric motor and a power transmitting member, and (b) a second electric motor disposed between the power transmitting member and a drive wheel of a vehicle, and a differential-state switching device operable to place the differential mechanism selectively in one of a differential state and a locked or non-differential state. The control device may include a switching control portion operable to control the differential-state switching device to place the differential mechanism selectively in one of the differential and locked states, and a power-source torque-change restriction control portion operable to restrict a change of an output torque of the engine upon switching of the differential mechanism between the differential and locked states.
