Abstract
【解決手段】 ECT_ECUは、急変速制御を終了すると判別すると(S104にてYES)、目標入力回転数NINCと実入力回転数NINとの偏差を算出するステップ(S106)と、目標入力回転数NINCと実入力回転数NINとの偏差が、予め定められた回転数よりも小さい場合(S108にてYES)、目標入力回転数NINTの初期値を、目標入力回転数NINCに設定するステップ(S110)と、目標入力回転数NINCと実入力回転数NINとの偏差が予め定められた回転数よりも大きい場合(S108にてNO)、目標入力回転数NINTの初期値を、実入力回転数NINに設定するステップ(S112)とを含む、プログラムを実行する。

Description
。
明する(以下、動力源100をエンジン100と記載する)。
ーブ242,244を固定シーブ238,240に対して接近する方向に押圧する油圧アクチュエータ246,248が設けられている。これら各シーブ238,240,242,244によって、ベルト236を巻掛けるためのV溝状のベルト巻掛け溝(プーリ溝)が形成されている。
のスプール4400の一端側にはスプリング4500が配置されるとともに、その一端側に信号圧を印加するための第1信号圧ポート4600が形成されている。そのスプール4400を挟んでスプリング4500とは反対側の端部に、信号圧を印加するための第2信号圧ポート4700が形成されている。
大の状態で、最低速側の変速比(最大変速比:最減速状態)が設定され、また、これとは反対にプライマリプーリ232に対するベルト236の巻き掛け半径が最大でかつセカンダリプーリ234に対するベルト236の巻き掛け半径が最小の状態で、最高速側の変速比(最小変速比:最増速状態)が設定される。
