Controller of driver for vehicles

A control apparatus for a vehicular drive system including a continuously-variable transmission portion operable as an electrically controlled continuously variable transmission, and a step-variable 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, a second electric motor disposed in a power transmitting path between the power transmitting member and a drive wheel of a vehicle, and a differential-state 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 step-variable transmission portion constituting a part of said power transmitting path and functioning as a step-variable transmission operable to perform a clutch-to-clutch shifting action by a releasing action of a coupling device and an engaging action of another coupling device, said control apparatus comprising:

• a step-variable shifting control portion configured to change an amount of racing of an input speed of said step-variable transmission portion during said clutch-to-clutch shifting action, depending upon whether the operation of said continuously-variable transmission portion as said electrically controlled continuously variable transmission is limited by said differential-state limiting device.
