Zusammenfassung:	To provide a hybrid vehicle that is less prone to a deterioration of fuel efficiency with reduced NO levels in exhaust gas.SOLUTION: A power distribution part 103 calculates an EG command power Pe and an MG command power Pm so that the vehicle runs in an assistance travel mode when a fuel consumption assistance cost, which is a reduction of fuel consumption per assistance power, exceeds a fuel consumption balance cost, while an exhaust NOx assistance cost, which is an NOx reduction per assistance power, exceeds a predetermined value.SELECTED DRAWING: Figure 2 【課題】ハイブリッド車両において、燃料消費量の悪化を抑制しつつ排気ガス中のＮＯｘ量を削減する。【解決手段】パワー分配部１０３は、アシスト電力あたりの燃料消費量の削減量である燃費アシストコストが燃費収支コストより大きく、かつ、アシスト電力あたりのＮＯｘ低減量である排気ＮＯｘアシストコストが所定値より大きいとき、アシスト走行モードによる走行を行うよう、ＥＧ指令パワーＰｅとＭＧ指令パワーＰｍを算出する。【選択図】図２
