Abstract
In a vehicular power transmitting apparatus provided with an electrically-controlled differential portion in which controlling an operating state of an electric motor controls a differential state of a differential mechanism, a control device for starting up a drive force source in an appropriate mode depending on a vehicle condition can be provided. The control device includes drive-force source start control means 86 for switching start modes of an engine 8 depending on a vehicle condition to achieve an appropriate start mode for the engine 8 depending on the vehicle condition, so that for instance a contracted drive range by a second electric motor can be avoided.
