図12を参照して、第2実施形態について説明する。第2実施形態については、上記第1実施形態で説明したものと同様の機能を有する構成要素には同一の符号を付して重複する説明は省略する。図12は、第2実施形態に係る車両の概略構成図である。第2実施形態の車両用駆動装置101において、上記第1実施形態の車両用駆動装置100と異なる点は、第二回転機MG2が変速部34を介して接続されている点である。
図13を参照して、第3実施形態について説明する。第3実施形態については、上記第1実施形態および第2実施形態で説明したものと同様の機能を有する構成要素には同一の符号を付して重複する説明は省略する。図13は、第3実施形態に係る車両の概略構成図である。第3実施形態の車両用駆動装置102において、上記第2実施形態の車両用駆動装置101と異なる点は、オーバードライブロックが可能な点である。オーバードライブロックは、エンジン回転数と出力軸33の回転数との変速比がオーバードライブの所定の変速比に固定された状態を示す。
図14を参照して、第4実施形態について説明する。第4実施形態については、上記第1実施形態から第3実施形態で説明したものと同様の機能を有する構成要素には同一の符号を付して重複する説明は省略する。図14は、第4実施形態に係る車両の概略構成図である。第4実施形態の車両用駆動装置103において、上記第3実施形態の車両用駆動装置102と異なる点は、第二遊星歯車機構20においてロー側変速比とハイ側変速比の切り替えがなされる点である。
図15を参照して、第5実施形態について説明する。第5実施形態については、上記第1実施形態から第4実施形態で説明したものと同様の機能を有する構成要素には同一の符号を付して重複する説明は省略する。図15は、第5実施形態に係る車両の概略構成図である。第5実施形態の車両用駆動装置104において、上記第1実施形態乃至第4実施形態の車両用駆動装置100,101,102,103と異なる点は、回転機MGが1つである点、噛合式係合装置90がエンジン1と回転機MGとを接続および遮断する点などである。
上記第1実施形態乃至第5実施形態では、第二制御におけるアクチュエータ70,85の推力が第二領域R2の推力とされたが、これには限定されない。第二制御におけるアクチュエータ70,85の推力は、第一制御における推力よりも大きな推力とされればよい。第二制御においてトルク変動制御がなされれば、中途停止状態の解消が促進される。第二制御において、アクチュエータ70,85の推力が第一制御の推力よりも大きな値とされることと、トルク変動制御との相乗効果により、中途停止状態の解消が容易となる。
上記各実施形態では、第一制御および第二制御において、アクチュエータ70,85に対する指示電流値が一定とされたが、これには限定されない。アクチュエータ70,85の指示電流値は、可変とされてもよい。例えば、第一制御において、アクチュエータ70の推力の大きさを第一領域R1の値に維持するように、指示電流値が調節されてもよい。この場合、アーマチュア64を含む移動部材66のストローク量Staの検出値または推定値に基づいて指示電流値を調整することが好ましい。
上記各実施形態において、第二制御におけるアクチュエータ70,85の推力は、移動部材のストローク量Staに応じて定められてもよい。上記第1実施形態のように、第二制御におけるアクチュエータ70の推力を第二領域R2(図10参照)の推力とすれば、中途停止状態の態様にかかわらず移動部材66をストロークさせ続けることが可能である。様々な中途停止状態のうち、ドグ歯61a,62aの歯先面61c,62cが接触した中途停止状態では、伝達スプリング71の付勢力が最大となる。この場合であってもリターンスプリング72および伝達スプリング71の付勢力に抗して移動部材66をストロークさせることができるようなアクチュエータ70の推力とすれば、係合の確実性や応答性を向上させることができる。しかしながら、傾斜面同士が接触する中途停止状態では、それほど大きな推力を必要としない場合がある。
上記各実施形態では、アクチュエータ70,85が電磁アクチュエータであったが、これには限定されない。アクチュエータ70,85は、電磁力によって推力を発生させることに代えて、油圧等によって推力を発生させるものであってもよい。油圧等によって推力を発生させる場合、アクチュエータ70,85の推力は、一定値とされても、スリーブや移動部材のストローク量に応じて可変とされてもよい。例えば、スリーブや移動部材のストローク量の増加に応じてアクチュエータ70,85の推力を増加させてもよい。
