To stabilize the combustion state of an engine at the time of transitional operation of the engine in a hybrid vehicle.SOLUTION: A control apparatus, for use in a hybrid vehicle that includes an engine, a motor as a traveling power source and a battery for charging power for supplying a motor, includes transitional operation control means. In a case where output-possible power of a battery and an absolute value of chargeable power are small at a time of transitional operation of the engine, the means executes a transitional operation of the engine, with an operating point of the engine controlled at a position with lower thermal efficiency and in a wider range of low output to high output than a normal operation and in a combustion state with a high margin down to a combustion limit than the normal operation.SELECTED DRAWING: Figure 4
【課題】ハイブリッド車両においてエンジンの過渡運転時にエンジンの燃焼状態を安定させること。【解決手段】エンジンと、走行用動力源のモータと、モータに供給するための電力を充電するバッテリとを備えたハイブリッド車両の制御装置であって、エンジンの過渡運転時に、バッテリの出力可能電力、及び、充電可能電力の絶対値が小さい場合には、エンジンの動作点を定常運転時よりも熱効率の低い位置かつ低出力から高出力の広い範囲で制御するとともに、定常運転時よりも燃焼限界までの余裕代が大きい燃焼状態にエンジンを制御する過渡運転を実施する過渡運転制御手段を備える。【選択図】図4
