Abstract
【解決手段】第1モータおよび第2モータならびにエンジンを駆動力源とするハイブリッド車両であって、前記第1モータの出力トルクを駆動軸側に伝達する歯車伝動機構と、前記エンジン以外の動力によって駆動されて前記歯車伝動機構へオイルを供給するオイル供給機構とを備えたハイブリッド車両の制御装置において、前記エンジンの運転を停止した状態で少なくとも前記第1モータの出力トルクによって前記ハイブリッド車両を走行させる際に、前記オイル供給機構から前記歯車伝動機構へ供給される推定オイル供給量が適量よりも少ない場合は、前記歯車伝動機構に掛かる負荷が低下するように運転状態を制限して前記第1モータを制御する(ステップS4)。

Description
Vehicle)であった場合は、通常のHV(Hybrid Vehicle)と比較して、上記のような「EV走行モード」の頻度が高くなる。そのようなPHVの場合は、「第1EV走行モード」が設定された場合であっても、その「第1EV走行モード」での連続運転時間が長くなり、「第2EV走行モード」が設定された場合のようにEOP19による遊星歯車機構の潤滑および冷却が必要になることがある。
特に、この発明では、エンジンの運転を停止しかつ前記ブレーキ機構によりキャリアの回転を止めた状態で第1モータおよび第2モータの両方の出力トルクによってハイブリッド車両を走行させる際に、上記のようにして、オイルの供給量が推定される。遊星歯車機構のキャリアの回転を止めて第1モータおよび第2モータの両方の出力トルクによってEV走行する場合には、遊星歯車機構においてはサンギヤとリングギヤとが互いに逆方向に回転することになり、それらサンギヤとリングギヤとの間の差回転が大きくなる。その結果、キャリアによって自転可能に支持されているピニオンギヤの回転数が増大し、その温度が上昇する。ピニオンギヤの温度が過度に上昇すると焼き付きや異常な摩耗などを起こしてしまうおそれがある。それに対して、この発明によれば、上記のように、キャリアの回転を止めて第1モータおよび第2モータの両方の出力トルクによってハイブリッド車両をEV走行させる場合は、オイル供給機構から遊星歯車機構へ供給されるオイルの供給量が推定される。そして、その推定したオイルの供給量が適量よりも少ない場合には、第1モータの運転状態が制限される。そのため、ピニオンギヤの温度上昇を抑制して焼き付きや異常な摩耗などの発生を防止することができる。
