Abstract
A vehicle driving apparatus configured with a drive power source, a fluid coupling, a transmission apparatus; and a control apparatus. A rotation of a drive input member driven by the drive power source is transmitted to a shift input member via the fluid coupling and a rotation of the shift input member is shifted by the transmission apparatus and then transmitted to an output member. When a state shift command for shifting from a non-transmission state to a transmission state is input into a control apparatus in a state in which the drive power source does not generate a driving force, the control apparatus performs a shift input rotation operation before engaging a frictional engagement element and shifting to the transmission state by causing the drive power source to generate the driving force and rotating the shift input member via the fluid coupling while maintaining the non-transmission state.
