Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce an HC emission amount stably when an engine is temporarily driven in a CD mode travel (a travel on a motor).SOLUTION: A plug-in hybrid vehicle includes a motor-generator and an engine as vehicle drive sources, and travels only on the motor-generator in priority as a CD mode in the state of a battery being charged from an external power source. When a required output exceeds an output limit SL of the motor-generator 2 at time t1, the engine is operated at constant torque, with an output of the motor-generator changing in accordance with the required output. Maintaining the engine at constant torque makes it possible to obtain a temperature rise of catalyzer stably, reducing a tail pipe HC reliably. 【課題】ＣＤモード（モータを用いた走行）中における一時的なエンジンの運転の際のＨＣ排出量を安定的に低減する。【解決手段】プラグインハイブリッド車両は、車両駆動源としてモータジェネレータとエンジンとを有し、外部電源によりバッテリが充電された状態では、ＣＤモードとして、モータジェネレータのみによる走行が優先的に行われる。時間ｔ１で要求出力がモータジェネレータ２の出力限界ＳＬを越えると、エンジンが一定トルクで運転され、モータジェネレータの出力が要求出力に応じて変化する。エンジンを一定トルクとすることで、触媒温度上昇が安定して得られ、テールパイプＨＣが確実に低減する。【選択図】図３
