Provided is a vehicle driving apparatus which can be miniaturized or improve fuel efficiency. Switching clutch C0 as a differential state switching device for selectively switching the power distribution mechanism 16 to an operating state (stepless state) operable as an electric continuously variable transmission, and a fixed shift state operable as a transmission having a fixed speed ratio, and Since the switching brake B0 is provided, the power distribution mechanism 16 is in a fixed shift state in the high speed travel or the high rotation region of the engine 8, and the output of the engine 8 is driven only by the mechanical power transmission path. 38), the conversion loss between power and electricity is suppressed, improving fuel economy. Further, in the high power region of the engine 8, the power distribution mechanism 16 is in a fixed shift state, so that the electric reaction force to be guaranteed of the first electric motor M1 can be reduced, so that the first electric motor M1 or the vehicle drive including the same can be reduced. The device 10 is downsized. |
