Abstract
A vehicle driving apparatus that can execute cranking of an internal combustion engine by transmitting a mechanical power from a rotor of a motor to an engine output shaft without executing an engaging/disengaging operation of a clutch. A driving apparatus of a hybrid vehicle includes a first speed change mechanism capable of receiving mechanical power from an engine output shaft by a first input shaft and transmitting the mechanical power to drive wheels, a second speed change mechanism capable of receiving the mechanical power from the engine output shaft and a rotor by a second input shaft engaged with the rotor and transmitting the mechanical power to the drive wheels, a first clutch capable of engaging the engine output shaft with the first input shaft, and a second clutch capable of engaging the engine output shaft with the second input shaft.
