ことを特徴とする。

前記フリクションディスクの位置を制御することで、前記第1断接手段は前記内燃機関と前記第1電動機との動力伝達を断接し、前記第2断接手段は前記内燃機関と前記被駆動軸との動力伝達を断接する、
ことを特徴とする。
車両後進時に、前記第2断接手段を切断するとともに前記接続切替手段を接続し、前記第2電動機を逆転方向に駆動する、
ことを特徴とする。
高負荷走行時に、前記第1断接手段と、前記第2断接手段と、前記接続切替手段をそれぞれ接続することにより、前記内燃機関と、前記第1電動機と、前記第2電動機の全てを駆動して走行する、
ことを特徴とする。
車両減速時に、前記接続切替手段を接続することにより前記第2電動機で回生発電するか、又は、前記第1断接手段と前記第2断接手段を接続することにより第1電動機で回生発電するか、又は、その両方を行なう、
ことを特徴とする。
車両発進時に、前記第2断接手段を切断するとともに前記接続切替手段を接続することにより前記第2電動機で発進する、
ことを特徴とする。

ことを特徴とする。
前記第2電動機による車両走行時に、前記第2断接手段を接続する際、前記第2電動機から前記被駆動軸に伝達される回転数と前記内燃機関の回転数とを略同一にした後、前記第2断接手段を接続する、
ことを特徴とする。
前記内燃機関による車両走行時に、前記第1断接手段を接続し、状況に応じて前記第1電動機を駆動するか又は前記第1電動機で回生発電する、
ことを特徴とする。
前記内燃機関の始動時に前記第2断接手段を切断するとともに前記第1断接手段を接続して前記第1電動機を駆動することにより前記内燃機関を始動する、
ことを特徴とする。
定常走行時に前記第1断接手段を接続し前記内燃機関により前記第1電動機にて回生発電するとともに、前記第2断接手段を切断し前記接続切替手段により適正な前記変速ギヤ対を介して前記第2電動機を駆動して走行する、
ことを特徴とする。
また、第2電動機による走行時には、内燃機関と被駆動軸とを断接する第2断接手段を切断し、第2電動機と被駆動軸とを断接する接続切替手段を接続することにより、内燃機関や第1電動機の連れまわりによる負荷の増大を抑制し燃費の向上に寄与することができる。
また、内燃機関の回転変動を平準化するフライホイールの両側に第1断接手段と第2断接手段を配置するので、フライホイールの両側にある空間を有効に利用することができ、これにより省スペース化を図るとともに、これら2つの断接手段が離れて配置されている場合に比べて、断接手段を制御するアクチュエータを一箇所に配置でき油圧回路や電気回路の単一化を実現できる。
エンジン1のクランク軸11の被駆動軸12側端部にはクランク軸11と一体にフライホイール13が設けられ、フライホイール13の内径部には被駆動軸12が軸受82を介して、クランク軸11と相対回転可能に取り付けられている。
クラッチ接続時においては、レリーズベアリング6によりレバー部53bがフライホイール13と当接する側に押され、ダイヤフラムスプリング53の弾性力によりプレッシャープレート52がフライホイール13側へ付勢される。この結果、フリクションディスク42がフライホイール13とプレッシャープレート52との間に狭持され、クラッチが接続される。
高速ギヤ対71は、第2モータ22の出力軸14の第2モータ22と反対側に設けられた高速駆動ギヤ71aと高速駆動ギヤ71aと噛合する被駆動軸12に設けられた高速従動ギヤ71bと、から構成され、低速ギヤ対72は、高速ギヤ対71より減速比が大きく、シフター73(接続切替手段)を挟んで高速ギヤ対71の高速駆動ギヤ71aの反対側に設けられた低速駆動ギヤ72aと、低速駆動ギヤ72aと噛合する被駆動軸12に設けられた低速従動ギヤ72bとから構成される。
図3はハイブリッド車両用動力伝達装置10の車両停止時の模式図である。図3に示すように、車両停止時においては、第1クラッチ31が接続され、第2クラッチ32は切断されるとともにシフター73は低速ギヤ対接続位置に位置する。
このように、車両の停車時に第1クラッチ31を接続し、第2クラッチ32を切断するとともにシフター73は低速ギヤ対接続位置に位置させることで、発進時にクラッチ31、32の断接、シフター73の切替なしに発進することができる。
また、第2モータ22を用いて発進、発進後低速走行及び後進することで、エンジン1の効率が悪い始動、発進後低速走行及び後進を第2モータ22が担うことで効率のよい走行が可能となる。
また、この状態において、駆動輪17からの動力を用いて第2モータ22で回生発電し不図示のバッテリーを充電することもできる。
この発進後低速走行時やこの低速走行からより高速での高速走行時を含めた定常走行時には、エンジン1の動力を第1モータ21で回生発電するととともに、発電した電力を第2モータ22に供給して、いわゆるシリーズ走行をすることにより走行負荷が大きい場合や、バッテリー残容量が低下した場合においても対応することができる。
例えば平坦路のような一定速度で走行可能な場合には、エンジン効率が良いためエンジン1で走行することが好ましく、図7の破線で描かれた矢印で示すように、エンジン1の駆動力がフライホイール13を介してファイナルギヤ15、差動装置16を介して駆動輪17に伝達される。
このとき、第1モータ21と第2モータ22との動力伝達を切断することにより、これら第1モータ21と第2モータ22を連れまわすことがなくなり負荷を軽減し、燃費を向上させることができる。
例えば、バッテリー残容量が多い状態で登坂路を走行する時には、第1モータ21でエンジン走行をアシストしたり、バッテリー残容量が低い状態で降坂路を走行する時には、第1モータ21で回生発電して充電することができる。
