Zusammenfassung:A failure determination device of a hybrid vehicle (100), includes an engine (1), a motor (3) arranged in series with the engine, a clutch (6) arranged between the motor and a driving wheel (8), a pressure adjusting mechanism that adjusts hydraulic pressure supplied to the clutch, and that performs wet start clutch control for adjusting the hydraulic pressure, supplied to the clutch at least upon starting, to the hydraulic pressure causing the clutch to slip, and a controller configured to calculate required driving force on the basis of accelerator opening, and calculate torque capacity of the clutch, required for transmitting the required driving force by the clutch, as target torque capacity (Tc), calculate actual torque (Te) of the engine and actual torque (Tm) of the motor, and calculate a torque deviation as a deviation between the target torque capacity and a sum of the actual torque of the engine and the actual torque of the motor.
