図1に示す車両3は、内燃機関4と電動機5とが直列に接続された駆動装置6(以下、前輪駆動装置と呼ぶ。)を車両前部に有するハイブリッド車両であり、この前輪駆動装置6の動力がトランスミッション7を介して前輪Wfに伝達される一方で、この前輪駆動装置6と別に車両後部に設けられた駆動装置1(以下、後輪駆動装置と呼ぶ。)の動力が後輪Wr(RWr、LWr)に伝達されるようになっている。前輪駆動装置6の電動機5と後輪Wr側の後輪駆動装置1の第1及び第2電動機2A、2Bとは、バッテリ9に接続され、バッテリ9からの電力供給と、バッテリ9へのエネルギー回生が可能となっている。符号8は、車両全体の各種制御をするための制御装置である。
油圧ブレーキ60は、いわゆる湿式多板式のブレーキであり、上記したように、複数の固定プレート35と、複数の回転プレート36とが軸方向に交互に配置され、これらのプレート35,36が環状のピストン37によって締結及び解放操作されるようになっている。湿式多板式のブレーキは、潤滑油としてのオイルにより両プレート35、36を潤滑するもので、オイルがダンパーの役割を果たすため、乾式クラッチに比べて締結時のショックが穏やかになる。
次に、ブレーキ強制解放を含めた油圧ブレーキ60のブレーキ解放制御について図12を参照しながら説明する。
制御装置8から油圧ブレーキ60の強制解放指令が出力された際に、車両3がFWD走行している場合、即ち、第1及び第2電動機2A、2Bがトルクを発生していない場合、前輪駆動装置6で前輪Wfを駆動しており、油圧ブレーキ60は動力伝達に寄与していないため、短時間の解放であれば随時許容されるので、即時に油圧ブレーキ60を解放する。このとき、通常のブレーキ解放制御と同様に、油圧ブレーキ60を解放することで、油圧ブレーキ60が潤滑される。
制御装置8から油圧ブレーキ60の強制解放指令が出力された際に、車両3がRWD又はAWD走行している場合、即ち、第1及び第2電動機2A、2Bが順方向のトルクを発生している場合、油圧ブレーキ60の解放を、順方向のトルクが略零となるまで待機し、後述する所定のタイミング(A)、(B)又は(C)で油圧ブレーキ60を解放する。
FWD走行となるまで待機して油圧ブレーキ60を強制解放する場合、即ち、FWD走行時のブレーキ強制解放制御については、上記(<ブレーキ強制解放制御 FWD走行時>)と同様であり、ここでは説明を省略する。
後輪駆動装置1が回生駆動指令を受けると通常、即時に油圧ブレーキ60を締結状態に制御するとともに第1及び第2電動機2A、2Bを回生駆動状態に制御するところ、制御装置8から油圧ブレーキ60の強制解放指令が出力されている場合には、第1及び第2電動機2A、2Bの回生駆動前に油圧ブレーキ60の解放を割り込ませ、さらに第1及び第2電動機2A、2Bを停止又は逆力行駆動するように制御する。これにより、通常のブレーキ解放制御と同様に、油圧ブレーキ60を解放することで、油圧ブレーキ60が潤滑される。図11に記載の走行モードにおいては、第1及び第2電動機2A、2Bの力行駆動から回生駆動への移行について記載されていないが、例えば、EV加速後に回生する場合、第1及び第2電動機2A、2Bの力行駆動から回生駆動への移行時に油圧ブレーキ60が解放される。
停車するまで待機して油圧ブレーキ60を強制解放する場合、即ち、停車時に油圧ブレーキ60を解放することについては、上記通常停車時のブレーキ解放と同様である。油圧ブレーキ60を解放することで油圧ブレーキ60によるリングギヤ24A、24Bの締結が解除され、摩擦締結されていた固定プレート35と回転プレート36とが離間し、固定プレート35と回転プレート36との間にオイルが供給される。停車時に、制御装置8から油圧ブレーキ60の強制解放指令が出力されている場合には、油圧ブレーキ60の解放に加え、第1及び第2電動機2A、2Bを逆力行駆動するように制御する。
また、断接手段として油圧駆動式の湿式多板式ブレーキを例示したが、これに限らず機械駆動式、電磁駆動式等を任意に選択できる。
また、サンギヤ21A、21Bに第1及び第2電動機2A、2Bを接続し、リングギヤ同士を互いに連結したが、これに限らずサンギヤ同士を互いに連結し、リングギヤに第1及び第2電動機を接続してもよい。
また、断接手段と一方向動力伝達手段は、3要素を有する差動装置の一要素に配置される場合に限らず、回転体と回転体との単純な動力伝達部に配置されるものであってもよい。
また、駆動源は2つある必要はなく、1つの駆動源により被駆動部を駆動する機構でもよい。
また、前輪駆動装置は、内燃機関を用いずに電動機を唯一の駆動源とするものでもよい。
また、駆動源として、電動機の代わりに、内燃機関等他の動力発生装置を用いてもよい。
また、本発明の駆動装置は、車両に限らず他の輸送機関、例えば船舶や航空機でもよい。
