Hybrid vehicle control apparatus with exhaust gas purification

A hybrid vehicle control apparatus which is capable of improving the deterioration of the emission performance unique to the hybrid vehicle during idle stop by purifying the exhaust gas remaining in the engine intake pipe (15), the cylinders (1a), the exhaust pipe (20) and the catalyst (21). The apparatus comprises two drive sources including an engine (1) operated by fuel combustion and an electric motor/generator (3) operated by electric energy. A residual exhaust gas purifier purifies the gas remaining in the intake pipe, the cylinders, the exhaust pipe and the catalyst of the engine.
