Beschreibung
Zusammenfassung:	To enable a hybrid vehicle to reduce amounts of harmful exhaust gas that is exhausted from an engine and vibration noise, without impairing travelling performance.SOLUTION: A control device of a hybrid vehicle calculates engine torque that can be outputted from an engine in accordance with a state quantity of the engine when torque required to the hybrid vehicle increases, sets a mode of assisting the engine in which insufficient torque is set to motor-generator torque outputted by a motor generator when the calculated engine torque is insufficient for the required torque, and transfers the mode to a charging mode in which charging of the secondary battery is started immediately after the assist mode ends when an amount of charge of a secondary battery is below a predetermined first reference amount of charge.SELECTED DRAWING: Figure 2 【課題】ハイブリッド車両において走行性能を損なうことなく、エンジンから排出される有害な排気ガスの排出量や振動騒音を低減する。【解決手段】ハイブリッド車両に対する要求トルクが増加する際には、エンジンの状態量に応じてエンジンから出力可能なエンジントルクを算出し、算出されたエンジントルクが要求トルクに対して不足する場合には当該不足分をモータジェネレータが出力するモータジェネレータトルクとしてエンジンのアシストモードとし、二次電池の充電量が所定の第１基準充電量以下である場合、アシストモードの終了後に直ちに二次電池の充電を開始する充電モードに移行させるハイブリッド車両の制御装置とする。【選択図】図２
