Patent ID: 6837320

Claim:
A hybrid vehicle comprising: an engine and a motor as its drive sources; and a control device, wherein the control device is configured to stop fuel supply to the engine at the time of vehicle deceleration, and to perform regenerative braking by the motor depending on a deceleration state, wherein said engine is a cylinder deactivation engine capable of switching between all cylinder operation for operating all cylinders and cylinder deactivation operation for deactivating more than one cylinder, said cylinder deactivation operation being performed depending on at least the deceleration state of said vehicle to reduce pumping losses of the engine, so that the regeneration efficiency of the motor is improved, and wherein said control device comprises: an abnormality detection device which detects abnormality in said cylinder deactivation engine; and a motor output limiting device which reduces the output of said motor when an abnormality in the cylinder deactivation engine is detected by said abnormality detection device.
