Description
図1において、車両100は、動力源として、内燃機関型のエンジン101と、モータ・ジェネレータ(MG)として機能する回転電機111、112とを搭載する、所謂、ハイブリッド車に構築されている。すなわち、車両100が本実施形態の回転電機システムを搭載している。この車両100は、車両全体がECU(Electronic Control Unit)1により統括制御されて、例えば、これらエンジン101や回転電機111、112が効率よく駆動されるようになっている。これらエンジン101や回転電機111、112の動力は、差動装置としての機能を有する動力伝達機構121などを介して駆動軸151に伝達される。これにより、車両100は、不図示の車輪が回転されて走行する。
図7に示すように、MOP11およびEOP21が組み込まれる油圧回路161の第1分配油路163や第2分配油路164には、MOP11の吐出側に調圧弁41が介在するように設置され、また、EOP21の吐出側にも調圧弁42が介在するように設置されている。これら調圧弁41、42は、MOP11やEOP21の吐出する圧力の変動の影響を受けないように、第1、第2分配油路163、164のそれぞれに吐出される潤滑油の油圧を一定の圧力に減圧するように設定されている。すなわち、調圧弁41、42は、減圧弁を構成している。
(第3の実施形態)
図9に示すように、ECU1は、上述の第1の実施形態のステップS18において、計時カウンタの計時する潤滑油の供給量を増加してからの継続時間が設定経過閾値を越えたか否かを繰り返し確認するのと並行して、ステップS11〜S13と同様の処理を実行し、電食発生の可能性ありと判定できない場合に、潤滑油の供給量を増加する処理を中断して制限するようになっている。
