Abstract
A hybrid vehicle implements a required traveling condition by generating a required driving force necessary to drive the vehicle even in the case where a supply source of a working fluid develops a malfunction. The hybrid vehicle is equipped with a motor which changes the phase difference between two rotors and an engaging/disengaging device which turns on/off the supply of a driving force of an internal combustion engine, the motor and the engaging/disengaging device being driven by a working fluid. The hybrid vehicle further includes a clutch which carries out the engagement/disengagement between a first drive shaft through which a driving force of an engine is transmitted and a second drive shaft through which a driving force of the motor is transmitted to wheels, an electrically-operated first pump capable of supplying hydraulic oil to a relative rotational force generator of the motor and the clutch, a mechanical second pump which is driven by the engine and which is capable of supplying the hydraulic oil to the clutch, and a solenoid selector valve for selectively switching the source of supply of the hydraulic oil to the clutch to the first pump or the second pump.
