Abstract
A hybrid vehicle includes: an internal combustion engine having an in-cylinder injection valve directly injecting fuel into a combustion chamber and a port injection valve injecting fuel into an intake port; and a motor generator, and causes a torque equal to a user required torque to act on a drive shaft by controlling output torques of the engine and motor generator. When a misfire is not detected, the hybrid vehicle operates the engine at an engine operation point at which an engine power satisfies an engine required power in a first engine operation line. When a misfire is detected, the hybrid vehicle operates the engine at an engine operation point at which the engine power satisfies the engine required power in a second engine operation line, causes one of the injection valves to inject an entire amount of fuel, and determines which one is abnormal.
