Description
図1は本発明の第1の実施形態に係る無段変速機を搭載した車両の概略構成図である。この車両は動力源としてエンジン1を備える。エンジン1の出力回転は、ロックアップクラッチ付きトルクコンバータ2、第1ギヤ列3、無段変速機(以下、単に「変速機4」という。)、第2ギヤ列5、終減速装置6を介して駆動輪7へと伝達される。第2ギヤ列5には駐車時に変速機4の出力軸を機械的に回転不能にロックするパーキング機構8が設けられている。
(a):アクセルペダルから足が離されている(アクセル開度APO=0)
(b):ブレーキペダルが踏み込まれている(ブレーキスイッチ47がON)
(c):車速が所定の低車速(例えば、15km/h)以下
(d):ロックアップクラッチが解放されている
なお、これらの条件は、言い換えると運転者に停車意図があることを判断する条件である。
次に、本発明の第2の実施形態を説明する。第2の実施形態では、メカオイルポンプ10mの構成が異なる。なお、第2の実施形態の基本構成(図1から図3)は第1実施形態と同一であり、その説明は省略する。
