Abstract
Description
図1は、この開示の実施の形態に従うハイブリッド車両(以下、単に車両と記載する)10の駆動システムの構成の一例を示す図である。図1に示すように、車両10は、制御部11と、走行用の動力源となる、エンジン13と、第1モータジェネレータ(以下、第1MGと記載する)14と、第2モータジェネレータ(以下、第2MGと記載する)15とを駆動システムとして備えている。エンジン13は、ターボチャージャ47を含む。
図2は、ターボチャージャ47を備えたエンジン13の構成の一例を示す図である。エンジン13は、たとえば、直列4気筒型の火花点火型の内燃機関である。図2に示すようにエンジン13は、たとえば、4つの気筒40a,40b,40c,40dが一方向に並べられて形成されるエンジン本体40を含む。
図3は、制御部11の構成の一例を示すブロック図である。図3に示すように、制御部11は、HV(Hybrid Vehicle)−ECU(Electronic Control Unit)62と、MG−ECU63と、エンジンECU64とを備える。
以上のような構成を有する車両10は、エンジン13および第2MG15を動力源としたハイブリッド(HV)走行モードやエンジン13を停止状態にするとともに第2MG15をバッテリ18に蓄積した電力で駆動して走行する電気(EV)走行モードなどの走行モードに設定または切り替えが可能である。各モードの設定や切り替えは、HV−ECU62により実行される。HV−ECU62は、設定または切り替えられた走行モードに基づいてエンジン13、第1MG14および第2MG15を制御する。
図9は、エンジン13、第1MG14、および第2MG15の動作点を決定する基本算出処理の一例を示すフローチャートである。このフローチャートに示される一連の処理は、HV−ECU62において所定周期毎に繰り返し実行される。
この開示の車両10においては、ターボチャージャ47の過給圧の応答遅れによる、エンジン13が発生するトルクの応答遅れを第1MG14または第2MG15の発生トルクで補うことができる。しかし、バッテリ18から放電される電力の許容値Woutが小さく制限されている場合には、バッテリ18の電力で駆動される、第1MG14または第2MG15は、エンジン13の発生するトルクの応答遅れを補う発生トルクを、十分、発生することができない虞がある。
(1) 前述した実施の形態においては、図10のステップS112で示したように、Woutに対応する動作ラインは、図11で示した3つの動作ラインから選択されることとした。しかし、これに限定されず、Woutに対応する動作ラインは、3つ以外の複数の動作ラインから選択されるようにしてもよい。この場合であっても、Woutが小さい場合は、大きい場合と比較して、図4または図11で示すマップ上における発生トルクに対する回転速度が高い動作ラインが選択されるようにする。
(1) 図1から図3で示したように、車両10は、エンジン13と、第1MG14と、エンジン13と第1MG14とカウンタシャフト25とが接続される遊星歯車機構20と、第1MG14によって発電される電力を蓄電可能であるとともに、蓄電された電力を第1MG14に供給可能なバッテリ18と、エンジン13および第1MG14を制御するように構成されたHV−ECU62とを備える。図1および図2で示したように、エンジン13は、エンジン13への吸気を過給するターボチャージャ47を含む。図4で示したように、エンジン13の回転速度と発生トルクとの関係を示すマップ上で定められる過給ラインL2は、それぞれ、マップ上の動作点で示されるエンジン13の発生トルクが当該過給ラインL2を上回っている状態であるときに、ターボチャージャ47により吸気を過給するラインである。
