Abstract
【解決手段】電子制御ユニットECUは、トランスアクスルに設けられたギアの歯打ち音を抑制すべく、エンジン回転速度が上昇されるようにエンジンENGの運転点を変更する歯打ち音抑制制御を実施する。そして電子制御ユニットECUは、このときの歯打ち音抑制制御の実施に際して、エンジン出力が低下されるようにエンジンENGの運転点を変更することで、エンジンENGの通常動作ラインを最適燃費ラインに近づけて、歯打ち音抑制制御の実施に伴う燃費の悪化を抑えるようにしている。
【選択図】図1
Description
本発明に係る車両の制御装置では、エンジン回転速度が上昇されるようにエンジンの運転点を変更してトランスアクスルに設けられたギアの歯打ち音を抑制する歯打ち音抑制制御を実施するようにしている。そして請求項1に記載の車両の制御装置では、このときの歯打ち音抑制制御の実施に際して、エンジン出力が低下されるようにエンジンの運転点を変更するようにしている。また請求項2に記載の車両の制御装置では、このときの歯打ち音抑制制御の実施に際して、その実施前のエンジンの等パワーラインよりも、エンジン出力が低下される側にエンジンの運転点を変更するようにしている。
図1は、本実施形態に係る車両の制御装置の適用されるハイブリッド車両の駆動系の構成を示している。同図に示すように、このハイブリッド車両は、車両の駆動源としてエンジンENGと2つの電動機(第1電動機MG1及び第2電動機MG2)とを備えている。またこのハイブリッド車両のトランスアクスルには、動力分配機構や電気式トルクコンバーターとして機能する2つの遊星歯車機構、すなわちフロント遊星歯車機構P1及びリア遊星歯車機構P2が備えられている。
Tm=−1/ρr×{Tpc−1/(1+ρf)×Te}
こうして第2電動機MG2の発生トルクTmを演算した後、電子制御ユニットECUは、今回の本ルーチンの処理を終了する。なおその後、電子制御ユニットECUは、先のステップS102,S103にて演算したエンジン回転速度Ne及びエンジントルクTeにより示される運転点へとエンジンENGを制御するとともに、ステップS104にて演算した補完トルクTmが得られるように第2電動機MG2を制御する。
(1)本実施形態では、車両のトランスアクスルに設けられたギアの歯打ち音を抑制すべく、エンジン回転速度が上昇されるようにエンジンENGの運転点を変更する歯打ち音抑制制御を実施するようにしている。そして本実施形態では、このときの歯打ち音抑制制御の実施に際して、エンジン出力が低下されるようにエンジンENGの運転点を変更するようにしている。すなわち、本実施形態では、このときの歯打ち音抑制制御の実施に際して、その実施前のエンジンENGの等パワーラインよりも、エンジン出力が低下される側にエンジンENGの運転点を変更するようにしている。こうしてエンジン出力が低下するように、或いはその実施前のエンジンENGの等パワーラインよりもエンジン出力が低下される側に、エンジンENGの運転点を変更した場合には、エンジン出力を一定に維持しつつエンジン運転点を変更した場合に比して、上記歯打ち音抑制ライン上に至るまでのエンジン回転速度の変更量を少なくすることができる。換言すれば、歯打ち音抑制ラインからより離れたところに、すなわち最適燃費ラインにより近いところに通常動作ラインを設定することができるようになる。そのため、本実施形態によれば、燃費の悪化を抑えつつ、トランスアクスルのギア歯打ち音を抑制することができるようになる。
続いて、本発明の車両の制御装置を具体化した第2実施形態を、図5を併せ参照して、上記実施形態と異なる点を中心に説明する。
(3)本実施形態では、電子制御ユニットECUは、アクセル操作量Accθに基づき車両の要求駆動力Tdcを演算するに際して、歯打ち音抑制制御の実施時には、その実施に伴うエンジントルクの低下分、要求駆動力Tdcを小さく演算するようにしている。そのため、本実施形態によれば、歯打ち音抑制制御の実施に伴うエンジン出力の低下に拘らず、車両の要求駆動力の推定結果を実情と一致させることができるようになる。
・第2実施形態では、電子制御ユニットECUは、歯打ち音抑制制御の実施時には、その実施に伴うエンジントルクの低下分、要求駆動力Tdcを小さく演算するようにしていた。もっとも、歯打ち音抑制制御の実施時におけるアクセル操作量Accθから推定される車両の要求駆動力とその実情との乖離が十分に無視し得る程度のものである場合には、こうした演算処理を割愛するようにしても良い。
