Abstract:
1. A control apparatus for a vehicular power transmitting system including (a) an electrically controlled differential portion operable to distribute an output of a drive power source of a vehicle to a first electric motor and a power transmitting member, (b) a second electric motor connected to a power transmitting path between an output shaft of said drive power source and a drive wheel of the vehicle, (c) a coupling device provided in the electrically controlled differential portion and operable to selectively switch the electrically controlled differential portion between a differential state and a non-differential state, and (d) an electric-energy storage device operable to store and discharge an electric energy supplied from the first or second electric motor, said control apparatus comprising: a torque-receiving-proportion control portion configured to control a proportion of torque values of a reaction torque corresponding to a torque acting on a predetermined member of said electrically controlled differential portion, which torque values are respectively received by said first electric motor and said coupling device, such that a ratio of the torque value received by the coupling device, with respect to said reaction torque, increases with an increase of a difference of an electric energy amount consumed by said second electric motor from an electric energy amount generated by said first electric motor.
