Description
図1を参照して、本実施の形態に係るハイブリッド車両1(以下、単に車両1と記載する)の全体ブロック図を説明する。車両1は、トランスアクスル8と、エンジン10と、ドライブシャフト17と、ディファレンシャルギヤ18と、PCU(Power Control Unit)60と、バッテリ70と、駆動輪72と、HV−ECU(Electronic Control Unit)200と、エンジンECU300とを含む。
以下に、エンジン10の通信異常時のフェールセーフ運転の一例について説明する。通信異常時におけるエンジン10の動作中には、フェールセーフ運転として、たとえば、エンジンECU300がエンジン10の出力を一定に保つ制御を行ないつつ、HV−ECU200が、エンジン10の出力軸にエンジントルクとは逆方向に第1MG20のトルクを作用させてエンジン回転速度Neを一定に保つ制御を行なうことが考えられる。
図2は、通信異常時における、エンジン10の動作中の動力分割装置40の各回転要素の回転速度の変化を示す共線図である。エンジン10、第1MG20および第2MG30が動力分割装置40によって機械的に連結されることによって、図2に示すように、第1MG20の回転速度(サンギヤSの回転速度)、エンジン回転速度Ne(キャリアCの回転速度)、および、第2MG30の回転速度(リングギヤRの回転速度)は、動力分割装置40の共線図上で直線で結ばれる関係(いずれか2つの回転速度が決まれば残りの回転速度も決まる関係)になる。
通信異常時に動作中のエンジン10を停止させる場合には、HV−ECU200は、第1MG20のトルク出力を停止する。図3は、第1MG20のトルク出力が停止される場合の動力分割装置40の各回転要素の回転速度の変化を示す共線図である。図3に示すように、第1MG20のトルク出力が停止されると、第1MG20のトルクによるエンジン回転速度Neの制限が解除される。そのため、エンジン回転速度Neは、エンジントルクTeによって上昇する。エンジンECU300は、このエンジン回転速度の上昇を検出することによってエンジン10を停止させる。すなわち、HV−ECU200は、エンジン回転速度を上昇させることによって、エンジン10の停止要求をエンジンECU300に間接的に送信する。
図4は、フューエルカット制御が実行される場合の動力分割装置40の各回転要素の回転速度の変化を示す共線図である。図4に示すように、燃料噴射が停止することによってエンジントルクが発生しなくなるため、エンジン回転速度Neは、エンジン10のフリクショントルクによって低下する。
上述の第1の実施の形態においては、スロットル開度を周期的に変動させることによってエンジン10の出力を周期的に変動させる場合について説明したが、本実施の形態においては、スロットル開度を変動させる制御に代えてエンジン10の回転中にフューエルカット制御を周期的に行なうことによってエンジン10の出力を周期的に変動させる。
上述の実施の形態においては、出力変動制御として、スロットル開度を周期的に変動させる構成と、フューエルカット制御を周期的に実行する構成とを一例として説明したが、特に、これらの制御に限定されるものではない。出力変動制御して、たとえば、点火時期を周期的に変更する構成であってもよいし、あるいは、エンジン10にバルブタイミングを変更可能な可変バルブタイミング機構を搭載している場合には、進角量を周期的に増減する構成であってもよい。
今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。
