ABSTRACT:
A control device for a vehicle which includes a differential portion controlling a differential state between the number of rotations of an input shaft connected to an engine, and the number of rotations of an output shaft connected to drive wheels, with controlling an operating state of an electric motor, and an automatic shifting portion forming part of a power transmitting path. The control device prevents degradation in operability of the vehicle, even in the presence of a shifting command resulting from a manual shift operation when the automatic shifting portion remains under a limited shifting state. More particularly, if the shifting command is present due to the manual shift operation, the differential state of the differential portion is controlled, thereby causing a variation in a drive force at a rate corresponding to the shifting command.
