Patent ID: 7901319

Claim:
A control apparatus for a vehicular drive system including a continuously-variable transmission portion which is operable as an electrically controlled continuously variable transmission and which has a differential mechanism operable to distribute an output of an engine to a first electric motor and a power transmitting member, a second electric motor connected to a power transmitting path between the power transmitting member and a first drive wheel of a vehicle, and a differential limiting device provided in said differential mechanism and operable to limit a differential function of said differential mechanism, for limiting an operation of said continuously-variable transmission portion as said electrically controlled continuously variable transmission, said vehicular drive system further including a third electric motor for driving a second drive wheel of the vehicle, said control apparatus comprising: differential-state switching means operated when driving of said second drive wheel by said third electric motor is selected, for switching said continuously-variable transmission portion to a continuously-variable shifting state in which the continuously-variable transmission portion is operable as said electrically controlled continuously variable transmission.
