Abstract
Description
まず、図1に基づいて車両の自動変速制御システムの概略構成を説明する。
車両の動力源であるエンジン11の出力軸(クランク軸)に、自動変速機12の入力軸が連結されている。この自動変速機12には、変速歯車機構(図示せず)と油圧制御回路13等が設けられている。変速歯車機構には、変速段(変速比)を切り換えるための複数のクラッチやブレーキ等の摩擦係合要素(図示せず)が設けられている。また、油圧制御回路13には、摩擦係合要素に作用させる油圧を制御する油圧制御弁14や、摩擦係合要素の作動油の油圧回路を切り換えるマニュアル弁17等が設けられている。このマニュアル弁17は、レンジセレクタ15の操作に連動してレンジ切換機構16によって駆動される。
図4及び図5に示すように、可変容量型のオイルポンプ34には、一回転当りの吐出量を変化させる容量可変部52が設けられている。切換動作機構48は、オイルポンプ34の容量可変部52に作用させる油圧を切り換えることでオイルポンプ34の吐出量を変更するものである。この切換動作機構48には、油圧回路を切り換えるための切換弁49が設けられている。この切換弁49は、マニュアル弁17と一体的に移動するように設けられている。切換弁49のスリーブ50には、油圧が導入される入力ポート51と、オイルポンプ34の容量可変部52に連通する供給ポート53と、ドレンポート54が設けられている。
図7に示す吐出量切換制御ルーチンは、AT−ECU22の電源オン期間中に所定周期で繰り返し実行され、特許請求の範囲でいう制御手段としての役割を果たす。
図13に示す吐出量切換制御ルーチンでは、まず、ステップ201で、現在のシフトレンジがDレンジ(つまりマニュアル弁17がDレンジ位置)であるか否かを判定する。このステップ201で、Dレンジではないと判定された場合には、ステップ202以降の処理を実行することなく、本ルーチンを終了する。
