Description
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、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、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し、ディーゼルエンジンであってもよい。K0クラッチ14、モータ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、プロペラシャフト12a及び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、クランク軸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軸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軸33の回転運動に変換する。
図3は、ECU100が実行するエンジン始動制御の一例を示したフローチャートである。本制御では、イグニッションがオンの状態で所定の周期ごとに繰り返し実行される。ECU100は、エンジン10の始動要求があるか否かを判定する(ステップS1)。ステップS1でNoの場合には、本制御は終了する。ステップS1でYesの場合にECU100は、アクセル開度が閾値α以上であるか否かを判定する(ステップS2)。閾値αは、運転者による加速要求の度合いが大きく点火時期の進角が必要となる最小値に設定されている。ステップS2は、判定部が実行する処理の一例である。
次に、上述した予測モータ回転数を算出するためのモータ回転数予測制御について説明する。モータ回転数予測制御は、予測部が実行する処理の一例である。図5は、モータ回転数予測制御の一例を示したフローチャートである。モータ回転数予測制御は、エンジン10の始動要求があってアクセル開度が閾値α以上の場合に実行される。
