Abstract
A control apparatus for a vehicular drive system including a differential mechanism including an electric motor. The drive system includes a switching clutch and switching brake to switch the transmission mechanism between a continuously-variable shifting state and a step-variable shifting state. A shifting control mechanism changes a manner of controlling shifting action of the transmission mechanism during shifting action of an automatic transmission portion, for reducing a shifting shock, depending upon whether a differential portion is placed in the continuously-variable shifting state in which engine speed is variable due to differential function irrespective of rotating speed of power transmitting member, or the non-continuously-variable shifting state in which the engine speed is more difficult to be variable than in the continuously-variable shifting state.
