PROBLEM TO BE SOLVED: To control execution of a catalyst warm-up operation at the starting of an engine in accordance with travel characteristics of CD and CS modes.SOLUTION: A hybrid vehicle includes: an engine provided with a catalyst in an exhaust system for purifying exhaust gas; a battery for charging and discharging; a travelling motor driven with power supplied from the battery; and a control apparatus for controlling travel of the vehicle by switching between a CD mode and a CS mode. The control apparatus includes a catalyst warm-up control part for performing control so as to perform a catalyst warm-up operation once again in restarting the engine, if a catalyst temperature is lower than a given value when the vehicle travels on the travelling motor while the engine is stopped, after a catalyst warm-up operation accompanying starting of the engine.SELECTED DRAWING: Figure 3 【課題】ＣＤモード及びＣＳモードの走行特性に応じてエンジン再始動時における触媒暖機運転の実行を制御する。【解決手段】本発明は、排気系に排気ガスを浄化する触媒を有するエンジンと、充放電を行うバッテリと、バッテリから供給される電力によって駆動する走行用モータと、を備え、ＣＤモードとＣＳモードとを切り替えて車両の走行制御を遂行する制御装置を備えたハイブリッド車両である。制御装置は、エンジンの始動に伴う触媒暖機運転後、エンジンを停止して走行用モータによって車両走行している間の触媒温度が所定値よりも低いとき、エンジンを再始動する際に再度触媒暖機運転を実行させるように制御する触媒暖機制御部を有する。このとき、触媒暖機制御部は、ＣＳモードでの走行中に停止状態にあるエンジンが再始動するときは、触媒暖機運転を実行しないように制御する。【選択図】図３
