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、エンジン13の発生トルクの応答遅れ自体は緩和できない。
(1) 前述した実施の形態においては、図11で示したように、加速を開始するときの動作点E1がNA域であることとした。しかし、加速を開始するときの動作点E1が、過給ラインL2を上回っている領域である過給域であってもよい。
(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、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10および図11で示したように、HV−ECU62は、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において、動作点E1から、動作点E1と比較してエンジン13の発生トルクおよび回転速度が高くターボチャージャ47により吸気が過給される動作点E3に移動させる場合、エンジン13の回転速度を一旦下げながら、エンジン13の発生トルクを上昇させるように、エンジン13および第1MG14を制御する。
