Description
(1)請求項1に記載の発明は、内燃機関の出力軸である機関出力軸の回転駆動力を、回転出力軸を介して駆動輪に伝達する車両に適用されて、車両の駆動特性として通常モードとパワーモードとを有する車両の制御装置において、前記機関出力軸の回転駆動力を前記回転出力軸に伝達する際の変速比を無段階に変更する無段変速機構を備え、アクセル開度が全開とされるときに前記内燃機関のスロットルバルブが全開とされるものであり、前記アクセル開度が全開とされるとき、パワーモードが選択されている場合には、目標回転速度まで機関出力軸の回転速度を上昇させる際に、前記内燃機関の出力のうち前記回転出力軸に伝達される駆動力が減少するように前記無段変速機構を制御することにより、通常モードが選択されている場合に比べて、前記機関出力軸の回転速度の上昇速度が大きくなるように前記無段変速機構を制御することをその要旨としている。
同図に示すように、ハイブリッド動力装置2においては、主動力源4が出力するトルクは回転出力軸6に伝達され、回転出力軸6からデファレンシャル8を介して駆動輪10に駆動力として伝達される。一方、走行のための駆動力を出力する力行制御、あるいはエネルギを回収する回生制御が可能なアシスト動力源であるモータジェネレータ12(以下、「MG2」)が設けられている。MG2は変速機14を介して回転出力軸6に連結され、MG2と回転出力軸6との間で伝達されるトルクは、変速機14にて設定される変速比に応じて増減される。
図2(A)に、上述したトルク分配機構(トルク合成機構としての機能も有する)としての遊星歯車機構20の共線図を示す。
変速機14は、一組のラビニョ型遊星歯車機構によって構成されている。すなわち、第1サンギヤ14aと第2サンギヤ14bとが設けられており、第1サンギヤ14aにショートピニオン14cが噛合するとともに、そのショートピニオン14cと第2サンギヤ14bとがこれより軸長の長いロングピニオン14dに噛合している。そして、ロングピニオン14dが各サンギヤ14a,14bと同心円上に配置されたリングギヤ14eに噛合している。各ピニオン14c,14dは、キャリヤ14fによって自転かつ公転自在に保持されている。従って、第1サンギヤ14aとリングギヤ14eとは、各ピニオン14c,14dと共にダブルピニオン型遊星歯車機構に相当する機構を構成している。また、第2サンギヤ14bとリングギヤ14eとは、ロングピニオン14dと共にシングルピニオン型遊星歯車機構に相当する機構を構成している。
同図に示すように、第2ブレーキB2によってリングギヤ14eを固定すれば、低速段Lowが設定され、MG2の出力したトルクが変速比に応じて増幅されて回転出力軸6に付加される。第1ブレーキB1によって第1サンギヤ14aを固定すれば、低速段Lowより変速比の小さい高速段Highが設定される。この高速段Highにおける変速比も「1」より小さいので、MG2が出力したトルクがその変速比に応じて増大させられて回転出力軸6に付加される。
尚、HV−ECU30には、機関運転状態や車両の走行状態を検出する各種センサからの検出結果が入力される。こうしたセンサとしては、例えば運転者要求であるアクセル開度ACCPを検出するアクセル開度センサ31、内燃機関16のクランク軸16aの回転速度である機関回転速度NEを検出する機関回転速度センサ16c、スロットルバルブ17の開度(以下、「スロットル開度」TA)を検出するスロットル開度センサ17a、及び回転出力軸6の回転速度、すなわち車速SPを検出する車速センサ6a等がある。また、E−ECU22、MG−ECU28、及びHV−ECU30は相互通信可能に接続されている。
(1)クランク軸16aの回転駆動力を回転出力軸6に伝達する際の変速比を無段階に変更するMG1を備えるものとした。また、HV−ECU30は、アクセル開度ACCPが全開とされるとき、目標回転速度NEtrgまで機関回転速度NEを上昇させる際に、パワーモードが選択されている場合には通常モードが選択されている場合に比べて、機関回転速度NEの上昇速度が大きくなるようにMG1の作動制御を実行するものとした。これにより、車両の加速度Gを早期に所定の大きさまで上昇させることができるようになる。また、車両の加速度Gを上昇させる際の上昇速度、いわゆる加加速度Jを大きなものとすることができるようになる。従って、パワーモードが選択されている場合と通常モードが選択されている場合とで内燃機関16の要求出力が同一となるときであれ、パワーモードが選択されている場合には通常モードが選択されている場合に比べて大きな加速感を得ることができるようになる。
・上記実施形態では、内燃機関としてガソリンエンジンについて例示したが、これをディーゼルエンジンに変更してもよい。
