Patent ID: 8036801

Claim:
A control apparatus for a vehicular drive system provided with a transmission mechanism constituted by a continuously-variable transmission portion operable as an electrically controlled continuously variable transmission, and a transmission portion, said continuously-variable transmission portion having 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, said transmission portion constituting a part of said power transmitting path, said control apparatus comprising: a differential-state switching device provided in said differential mechanism and operable to place said continuously-variable transmission portion in a selected one of a continuously-variable shifting state in which said continuously-variable transmission portion is operable as said electrically controlled continuously variable transmission portion, and a non-continuously-variable shifting state in which the continuously-variable transmission portion is not operable as the electrically controlled continuously variable transmission; and shifting control means for changing a manner of controlling a shifting action of said transmission mechanism during a shifting action of said transmission portion, depending upon whether the differential-state switching device places said continuously-variable transmission portion in said continuously-variable shifting state or in said non-continuously-variable shifting state, wherein said shifting control means positively changes a speed of said engine during the shifting action of said transmission portion, in said non-continuously-variable shifting state of said continuously-variable transmission portion, by using said first electric motor and/or said second electric motor.
