Abstract:
1. A control device for a vehicular drive system including a differential portion having a differential mechanism operable to distribute an output of an engine to a first electric motor and a power transmitting member, and a second electric motor disposed in a power transmitting path between the power transmitting member and a drive wheel of a vehicle, said control device comprising: a differential limiting device provided in said differential mechanism and operable to limit a differential function of said differential mechanism for thereby limiting a differential function of said differential portion; and a torque-response control portion that controls a response of a change of a torque to an operation of a manually operable vehicle accelerating member, the torque being an input torque of said differential portion, the input torque changing according to the operation of the manually operable vehicle accelerating member, and the torque-response control portion controlling the response of the change of the input torque depending upon whether the differential function of said differential mechanism is limited or not.
