Abstract
A control apparatus for a vehicular drive system including (a) an electrically controlled differential portion having a differential mechanism and operable to control a differential state between its input and output speeds by controlling an operating state of an electric motor connected to a rotary element of the differential mechanism, and (b) a transmission portion which constitutes a part of a power transmitting path between the electrically controlled differential portion and a drive wheel of a vehicle, the control apparatus including a non-iso-power shifting control portion configured to implement a non-iso-power shifting control of the vehicular drive system (differential portion) when a required special shifting action of the transmission portion not according to a shifting boundary line map should be restricted.
