ABSTRACT:
A hybrid vehicle comprises an engine and a motor as its drive sources. The hybrid vehicle also comprises a control device which stops the fuel supply to the engine at the time of vehicle deceleration, and performs regenerative braking by the motor depending on the deceleration state, in which the engine is a cylinder deactivation engine capable of switching between all cylinder operation for operating all cylinders and cylinder deactivation operation for deactivating at least one or more cylinders. The cylinder deactivation operation is conducted during deceleration state of the vehicle to reduce pumping losses of the engine so that the regeneration efficiency of the motor is improved. The control device comprises an abnormality detection device which detects abnormality in the cylinder deactivation engine, and a motor output limiting device which limits the output of the motor in response to the detection of the abnormality.
