Abstract
Description
図1は、本実施形態に係る油圧制御装置10の構成図である。油圧制御装置10は、例えば、無段変速機(CVT)である変速機12を搭載する車両14に適用される。
以上のように構成される本実施形態に係る油圧制御装置10の動作について、図4A〜図13を参照しながら説明する。ここでは、主として、出力圧センサ26が検出した出力圧P1、又は、ライン圧センサ60が検出したライン圧PHを用いて、制御ユニット28がモータ32に対するフィードバック制御を行うことにより、第2ポンプ30を最適に駆動制御させる場合について説明する。ここでは、必要に応じて、図1〜図3も参照しながら説明する。
上記のフィードバック制御の動作説明に先立ち、油圧制御装置10の基本的な動作について説明する。この基本的な動作では、主として、リザーバ18から第1ポンプ20等を介して無段変速機構56にオイルを供給する油圧系統の動作について説明する。
図5は、油路50(図1及び図2参照)を介した無段変速機構56へのオイル供給が、第1ポンプ20からチェック弁58を介した第1オイルの供給より、第2ポンプ30からの第2オイルの供給に切り替わる場合を図示したタイミングチャートである。図5中、PDRは、油路50bを介してドライブプーリ56bに供給されるオイルの圧力(側圧、プーリ圧)である。
具体的に、図6に示すように、第2ポンプ30の回転数Nepの指令値(指令回転数)の大きさによって、下記の課題が発生する。
このような課題に対して、本実施形態に係る油圧制御装置10では、出力圧P1又はライン圧PHを用いたモータ32(第2ポンプ30)に対するフィードバック制御を行うことにより、第2ポンプ30を最適に制御し、車両14の燃費の低下と油圧応答遅れの発生とを抑制できるようにしている。その制御手法について、図7〜図13を参照しながら詳細に説明する。
以上説明したように、本実施形態に係る油圧制御装置10によれば、第2ポンプ30における第1オイルの吸入側(上流側)に出力圧センサ26が配設されると共に、第2オイルの吐出側(下流側)にライン圧センサ60が配設されている。制御ユニット28(の制御部28i)は、出力圧センサ26が検出した出力圧P1、又は、ライン圧センサ60が検出したライン圧PHに基づいてモータ32を制御することにより、第2ポンプ30の駆動を制御する。
