Description
まず、図1を参照して、本発明の一実施形態である車両用油圧制御装置が搭載される車両の一構成例について説明する。
次に、図2を参照して、油圧回路200の構成について説明する。
次に、図3を参照して、可変容量MOP201の構成について説明する。
このような構成を有する車両用油圧制御装置では、ECU300が以下に示す油圧制御処理を実行することにより、実吐出油圧の測定装置を用いることなく、可変容量MOP201を応答性よく制御する。以下、図4〜図7を参照して、油圧制御処理を実行する際のECU300の動作について説明する。
次に、図8及び図9を参照して、上記ステップS2における吐出流量/吐出油圧算出処理について詳しく説明する。
まず、図8を参照して、本発明の第1の実施形態である吐出流量/吐出油圧算出処理の流れについて説明する。
次に、図9を参照して、本発明の第2の実施形態である吐出流量/吐出油圧算出処理の流れについて説明する。
可変容量MOP201の目標吐出容量を算出する際、可変容量MOP201の容積効率が低くなるのに応じて可変容量MOP201の目標吐出容量を大きく設定することが望ましい。具体的には、可変容量MOP201のオイル漏れ量は、MOP軸回転数、吐出油圧、及び油温によって変化し、オイル漏れ量が多くなると可変容量MOP201の実吐出油圧が目標吐出油圧に対して不足する。そこで、図10に示すように、可変容量MOP201の目標吐出容量を算出する際には、ECU300は、目標ライン圧及びMOP軸回転数と可変容量MOP201の容積効率との関係を示す可変容量MOP201の吐出容量別のマップから目標ライン圧とMOP軸回転数及び吐出容量とに対応する容積効率を読み出す。そして、ECU300は、読み出された容積効率分の流量を上乗せした流量を可変容量MOP201の目標流量として算出し、算出された目標流量を用いて可変変量MOP201の目標吐出容量を算出することが望ましい。
ECU300は、EOP202を現在の動作点の効率よりも効率が良い動作点で駆動させた場合において、EOP202の駆動電力量の増加分に対応する燃料消費量より可変容量MOP201の吐出流量の減少に伴うエンジン1の燃料消費量の減少量が大きい場合、現在の動作点の効率よりも効率が良い動作点でEOP202を駆動すると共に、可変容量MOP201の吐出流量を減少させる吐出流量制御処理を実行することが望ましい。以下、図11,図12を参照して、この吐出流量制御処理について詳しく説明する。
ECU300は、エンジン1への燃料供給が停止している場合、可変容量MOP201の目標吐出容量を最大吐出容量に設定する吐出容量制御処理を実行することが望ましい。以下、図15を参照して、この吐出流量制御処理について詳しく説明する。
本実施形態は、無段変速機(CVT)を変速機として備える車両に本発明を適用したものであるが、本発明は、本実施形態に限定されることはなく、図18に示すような自動変速機(AT)を変速機として備える車両にも適用することができる。但し、ATを備える車両に本発明を適用する場合には、目標変速比の代わりにギヤ段をパラメータとして用いてT/M目標流量を算出する。以下、図18に示すATを備える車両の構成について説明する。なお、上述した図1に示す車両Veと同様の構成については、説明を省略してその参照符号を引用する。
