Abstract:
1. A control device for vehicle drive apparatus, the vehicle drive apparatus including a continuously variable transmission part having a differential mechanism distributing an output of an engine to a first electric motor and a transmitting member, and a second electric motor disposed in a power transmitting path from the transmitting member to drive wheels, and operating as an electrically controlled continuously variable transmission; and an automatic transmission part constituting a portion of the power transmitting path and functioning as an automatic transmission; the control device comprising: a differential state switching device that is disposed in the differential mechanism and that selectively switches the continuously variable transmission part between a continuously variable shifting state for performing an electrically controlled continuously variable shifting operation, and a shifting state not for performing the electrically controlled continuously variable shifting operation; and an input torque limit means that limits, upon switching of the continuously variable transmission part from the continuously variable shifting state to the shifting state not performing the electrically controlled continuously variable shifting operation being unable, an input torque inputted into the continuously variable transmission part to a value not more than a predetermined torque.
