| Summary: | The power output apparatus of the invention increases a tentative engine power demand Petmp required for an engine, during a catalyst degradation detection time when degradation detection of an emission control catalyst is performed according to a variation in output of an oxygen sensor provided downstream of the emission control catalyst. The smaller between an increased power demand Peu by increasing the tentative engine power demand Petmp and an upper limit of a chargeable range of a battery is set to an engine power demand Pe* of the engine. Upon satisfaction of an auto engine stop condition that the engine power demand Pe* decreases below a preset reference power Pref, the engine is controlled to be driven at idle. |
