Abstract
A hybrid vehicle driven using power from an internal combustion engine and power from an auxiliary power source, includes an exhaust gas purification catalyst disposed in an exhaust passage of the engine. The catalyst stores oxygen and a power controller causes the engine to discharge exhaust gas including excess oxygen and causes the auxiliary power source to assist the engine in driving the vehicle when oxygen is to be stored in the exhaust gas purification catalyst. It is possible to supply the catalyst with exhaust gas containing excess oxygen while inhibiting the driveability from being adversely affected.
