Abstract
Description
上記の目的を達成するために講じられた本発明の解決原理は、ハイブリッド車両の動力伝達系に設けられた遊星歯車機構のプラネタリキャリアに支持されているピニオンギヤの回転力をオイルポンプに伝達する構成とし、このピニオンギヤの回転に伴ってオイルポンプが駆動するようにしている。つまり、内燃機関の駆動時には、この内燃機関に連結されたプラネタリキャリアの回転によりピニオンギヤを介してオイルポンプに動力が伝達され、内燃機関が停止している走行時(駆動輪の回転時)には、この駆動輪に連結されたリングギヤの回転によりピニオンギヤを介してオイルポンプに動力が伝達される構成としている。
具体的に、本発明は、内燃機関の出力軸が連結されたプラネタリキャリアと、電動機が連結されたサンギヤと、駆動輪が連結されたリングギヤとを有する遊星歯車機構が動力伝達系に備えられたハイブリッド車両を前提とする。このハイブリッド車両に対し、前記遊星歯車機構のプラネタリキャリアに回転自在に支持されているピニオンギヤと、オイルポンプの駆動軸とを動力伝達可能に連結した構成としている。
エンジン1は、ガソリンエンジンやディーゼルエンジンなど、燃料を燃焼させて動力を出力する公知の動力装置であって、吸気通路11に設けられたスロットルバルブ13のスロットル開度、燃料噴射量、点火時期などの運転状態を制御できるように構成されている。また、燃焼後の排気ガスは排気通路12を経て図示しない酸化触媒等の排気浄化装置による浄化が行われた後に大気中に放出される。
第1モータジェネレータMG1は、永久磁石からなるロータMG1Rと、3相巻線が巻回されたステータMG1Sとを備えた交流同期発電機であって、発電機として機能するとともに電動機(電動モータ)としても機能する。また、第2モータジェネレータMG2も同様に、永久磁石からなるロータMG2Rと、3相巻線が巻回されたステータMG2Sとを備えた交流同期発電機であって、電動機(電動モータ)として機能するとともに発電機としても機能する。
図1に示すように、動力分割機構3は、複数の歯車要素の中心で自転する外歯歯車のサンギヤSfと、このサンギヤSfに噛み合いながらその周囲を自転しつつ公転する外歯歯車の複数のピニオンギヤPfと、このピニオンギヤPfと噛み合うように中空環状に形成されたリングギヤRfと、ピニオンギヤPfを支持するとともに、このピニオンギヤPfの公転を通じて自転するプラネタリキャリアCfとを有する遊星歯車機構によって構成されている。プラネタリキャリアCfはエンジン1側のインプットシャフト21に回転一体に連結されている。サンギヤSfは、第1モータジェネレータMG1のロータMG1Rに繋がるモータ軸41に回転一体に連結されている。
次に、デファレンシャル装置8に向けてトルクを伝達するギヤ列5について説明する。
次に、本実施形態の特徴とする構成であるオイルポンプ9への動力伝達経路について説明する。
ECU100は、エンジン1の運転制御、エンジン1およびモータジェネレータMG1,MG2の協調制御などを含む各種制御を実行する電子制御装置であって、CPU(Central Processing Unit)、ROM(Read Only Memory)、RAM(Random Access Memory)およびバックアップRAMなどを備えている。
このように構成されたハイブリッド車両HVは、ドライバによるアクセルペダルの踏み込み量に対応するアクセル開度Accと車速Vとに基づいて、駆動輪6に出力すべきトルク(要求トルク)を計算し、この要求トルクに対応する要求駆動力により走行するように、エンジン1とモータジェネレータMG1,MG2とが運転制御される。
次に、前述した如く構成された動力伝達系により動力が伝達されることによるオイルポンプ駆動状態について説明する。ここでは、前記HV走行時およびEV走行時それぞれについてのオイルポンプ9の駆動状態について、図4および図5の共線図を用いて説明する。
図4はHV走行時における動力分割機構3の各回転要素の回転速度の一例を表す共線図である。
図5はEV走行時における動力分割機構3の各回転要素の回転速度の一例を表す共線図である。
図6は、比較例として、エンジンaの出力軸にオイルポンプbが直結された動力伝達系の構成(この図6では動力伝達系の上側半分のみを示している)であり、図7は、この図6に示した動力伝達系を有するハイブリッド車両のEV走行時における動力分割機構cの各回転要素の回転速度を表す共線図である。なお、図6に示した動力分割機構cにおける各ギヤについて、前記実施形態のものと同様のギヤについては同じ符号を付している。また、図6における符号dはリングギヤRfに噛み合うカウンタドリブンギヤであり、符号eは第2モータジェネレータMG2に繋がると共にカウンタドリブンギヤdに噛み合うカウンタドライブギヤである。
次に、変形例1について説明する。本変形例は、オイルポンプ9の配設位置が前記実施形態のものと異なっている。従って、ここでは前記実施形態との相違点についてのみ説明する。
次に、変形例2について説明する。本変形例は、動力伝達系の構成が前記実施形態のものと異なっている。従って、ここでも前記実施形態との相違点についてのみ説明する。
次に、変形例3について説明する。本変形例は、オイルポンプ9の配設位置が前記変形例2のものと異なっている。従って、ここでは前記変形例2との相違点についてのみ説明する。
次に、変形例4について説明する。本変形例は、本発明をFR(フロントエンジン・リアドライブ)方式のハイブリッド車両に適用した場合である。
以上の実施形態および各変形例では、FF方式のハイブリッド車両HVおよびFR方式のハイブリッド車両HVに本発明を適用した場合について説明したが、本発明はこれに限られることなく、4輪駆動方式のハイブリッド車両にも適用できる。
