Abstract
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, the control device including a differential limiting device provided in the differential mechanism and operable to limit a differential function of the differential mechanism for thereby limiting a differential function of the differential portion, and a torque-response control portion for controlling a response of a change of an input torque of the differential portion to an operation of a manually operable vehicle accelerating member, depending upon whether the differential function of the differential mechanism is limited or not.
