A control apparatus for a vehicular power transmitting system including (a) an electrically controlled differential portion having a differential mechanism disposed between an engine and a vehicle drive wheel, and a differential-portion electric motor operatively connected to the differential mechanism such that a differential state of the differential mechanism is controllable by controlling an operating sate of the electric motor, and (b) a transmission portion constituting a part of a power transmitting path, the control apparatus including a shifting-point changing portion configured to change a shifting point at which a determination to perform a shifting action of the transmission portion is made, such that the shifting point is changed according to a shifting response of the transmission portion. Alternatively, the control apparatus includes a shift-control start-point changing portion configured to change a shift-control start point at which the determination to perform the shifting action is made, such that the shift-control start point is changed according to the shifting response of the transmission portion, and a compulsory shift-control starting portion configured to make the determination when an operating point of the differential-portion electric motor has reached the shift-control start point.
