Description
以下、本発明の実施形態について、添付図面を参照しつつ説明する。ただし、図面中、各部の寸法、比率等は、実際のものと完全に一致するようには図示されていない場合がある。また、図面によっては細部が省略されて描かれている場合もある。さらに、各図間に描かれている各要素の縮尺が異なっている場合がある。
図1は、ハイブリッド車両1の概略構成図である。ハイブリッド車両1には、内燃機関に相当するエンジン10から駆動輪13までの動力伝達経路に、K0クラッチ14、モータジェネレータ(Motor Generator:MG)15、トルクコンバータ18、及び変速機19が順に設けられている。エンジン10及びモータジェネレータ15は、ハイブリッド車両1の走行用駆動源として搭載されている。エンジン10は、内燃機関の一例であり、例えばV型6気筒ガソリンエンジンであるが気筒数はこれに限定されず、直列型のガソリンエンジンであってもよい。K0クラッチ14、モータジェネレータ15、トルクコンバータ18、及び変速機19は、変速ユニット11内に設けられている。変速ユニット11と左右の駆動輪13とは、ディファレンシャル12を介して駆動連結されている。
図2は、エンジン10の概略構成図である。エンジン10は、気筒30、ピストン31、コネクティングロッド32、クランクシャフト33、吸気通路35、吸気弁36、排気通路37、及び排気弁38を有している。図2には、エンジン10が有する複数の気筒30のうちの一つのみが表示されている。気筒30では混合気の燃焼が行われる。ピストン31は、各気筒30に往復動可能に収容され、エンジン10の出力軸であるクランクシャフト33にコネクティングロッド32を介して連結されている。コネクティングロッド32は、ピストン31の往復運動をクランクシャフト33の回転運動に変換する。ピストン31は、気筒30の軸方向に沿って、気筒30のシリンダボア内周壁30aに摺接するように往復運動を行う。
このように構成されたエンジン10に対して、ECU100は、ハイブリッドモード又はエンジンモードにおいて所定の停止条件が成立した場合に自動停止させ、所定の自動再始動条件が成立した場合に自動再始動させる間欠運転制御を実行する。自動停止条件は、例えばハイブリッドモード又はエンジンモードにおいてアクセル開度が0になった場合である。自動再始動条件は、例えばエンジン10の自動停止後にアクセル開度が0よりも大きくなってエンジン10への要求トルクが0よりも大きくなった場合である。
以下、始動時制御について、図3及び図4を参照しつつ説明するが、説明を分かり易くする為、図3に示すフローチャートに沿った制御の具体的内容の説明に先立ち、始動時制御の概略構成について説明する。
以上のように、本実施形態では、噴射回数が第1目標回数に到達した場合に、始動時制御の終了に先行して直噴インジェクタ41dのみを用いる第1燃料噴射形態からポートインジェクタを用いる第2燃料噴射形態へ切り替えるため、シリンダボア内周壁への燃料の付着が抑制される。
つぎに、図5及び図6を参照して、変形例について説明する。図5に例示するフローチャートでは、図3に例示するフローチャートにおけるステップS6がステップS61に置き換えられている。
