Zusammenfassung: | To provide a driving force control device of a hybrid vehicle which can satisfy requested drive force while restraining emission from being deteriorated under such a condition that quantity of particulates accumulated within a particulate filter is little.SOLUTION: A driving force control device of a hybrid vehicle is configured so as to switch from motor travel mode to hybrid travel mode on the basis of charging residual quantity of a power storage device and to set the charging residual quantity of a power storage device, which functions as threshold switching from motor travel mode to hybrid travel mode, to be higher (step S7) when the particulate quantity accumulated in the particulate filter is below prescribed quantity (Yes at step S2) and at the same time to set upper limit output of an internal combustion engine when traveling at the hybrid travel mode(step S8) to be lower than when quantity of particulates accumulated in a particulate filter is prescribed quantity or more (No at step S2).SELECTED DRAWING: Figure 2
【課題】パティキュレートフィルタ内に堆積したパティキュレートの量が少ない条件下でのエミッションの悪化を抑制しつつ、要求駆動力を充足できるハイブリッド車両の駆動力制御装置を提供する。【解決手段】蓄電装置の充電残量に基づいてモータ走行モードからハイブリッド走行モードに切り替えるように構成され、パティキュレートフィルタに堆積したパティキュレートの量が予め定められた所定量未満の場合(ステップS2でYes)には、パティキュレートフィルタに堆積したパティキュレートの量が所定量以上である場合(ステップS2でNo)よりも、モータ走行モードからハイブリッド走行モードへの切り替え閾値となる蓄電装置の充電残量を高く設定する(ステップS7)とともに、ハイブリッド走行モードでの走行時における内燃機関の上限出力を低く設定する(ステップS8)。【選択図】図2 |
