Abstract
Description
T:伝達トルク
α:プーリのシーブ角
μ:ベルトとプーリとの間の摩擦係数
R:ベルトとプーリとの接触半径
[0027]
理論下限値=(Tcosθ)/(2μR)
T:伝達トルク
θ:プーリのシーブ角
μ:ベルトとプーリとの間の摩擦係数
R:ベルトとプーリとの接触半径
[0028]
そして、一方が理論下限値に制限される場合は、他方の圧を上げて、プライマリプーリ2とセカンダリプーリ3との間で変速に必要な差推力が確保されるようにする。
[0029]
さらに、アクセルが解放されて、ブレーキが踏み込まれる、又は、登坂時等で、車両が減速し、図2のAPO=0/8の線に沿ってCVT1が最Lowに向けてダウンシフトするLow戻し変速時であって、停車直前または変速比が変動しない変速定常時(最Low)には、プライマリ圧理論下限値よりも低下させることによって発生する可能性のあるベルト滑りを抑制するために、停車直前または変速比が変動しない変速定常時を除き、プライマリ圧Ppriを上記理論下限値よりも下げることが可能である。
[0030]
そこで、変速機コントローラ12は、以下に説明するLow戻し変速時の油圧降下制御を行うことにより、プライマリ圧Ppriを上記理論下限値よりも下げ、これによってCVT1が搭載される車両のLOW戻り性を向上させつつ、オイルポンプの小型化によって燃費をさらに向上させることが可能となる。
[0031]
図3は、変速機コントローラ12が行うLow戻し変速時の油圧降下制御の内容を示したフローチャートである。これを参照しながら本制御の内容及びその作用効果について説明する。説明中、適宜、図5に示すタイムチャートを参照する。図5に示すタイムチャートは、Low戻し変速時の油圧降下制御が行われるときの様子を示している。
[0032]
まず、S1では、変速機コントローラ12は、Low戻し変速中か判断する。アクセル開度ゼロかつブレーキペダルが踏み込まれている場合、又は、アクセル開度ゼロかつ車両の減速度が所定値よりも大きい場合(登坂時)は
必要なセカンダリ圧Psecを図4に示すテーブルを参照して演算する。なお、図4には必要プライマリ圧も図示されているが、Low戻し変速時の油圧降下制御では使用しない。
[0039]
S6では、変速機コントローラ12は、プライマリ圧理論下限値とプライマリ圧実測下限値との差(図5中Y1)を必要セカンダリ圧に加算し(図5中Y2)、補正後必要セカンダリ圧を演算する。そして、変速機コントローラ12は、セカンダリ圧Psecが補正後必要セカンダリ圧になるように、セカンダリ圧Psecを制御する。具体的には、セカンダリ圧Psecを調圧するソレノイドバルブを制御する。
[0040]
S7では、変速機コントローラ12は、S6でセカンダリ圧Psecを制御した結果、得られる実セカンダリ圧Psecをセカンダリ圧センサ15sによって検出し、これとプライマリプーリ2とセカンダリプーリ3の受圧面積の比とに基づきプライマリバランス圧に換算する(図5中Y3)。
[0041]
S8では、変速機コントローラ12は、プライマリバランス圧からダウンシフトに必要な差推力分(必要な差推力をプライマリプーリ2の受圧面積で割った値)を引き、目標プライマリ圧を演算する(図5中Y4)。目標プライマリ圧は、プライマリ圧理論下限値よりも低くなるが、プライマリ圧実測下限値よりも高いため、プライマリ圧実測下限値によって制限されることはない。そして、変速機コントローラ12は、プライマリ圧Ppriが目標プライマリ圧になるようにプライマリ圧Ppriを制御する。具体的には、プライマリ圧Ppriを調圧するソレノイドバルブを制御する。
[0042]
図5では、時刻t1からt2までは、油量収支が実際に不足していないため、実セカンダリ圧を補正後必要セカンダリ圧まで上昇させる。これは、プライマリ圧理論下限値をプライマリ圧実測下限値に変更することにより、目標プライマリ圧をプライマリ圧実測下限値まで低下させることが可能であるが、プライマリ圧を低下させることによって発生する懸念のあるベルト滑りの発生を抑制するために、油量収支が実際に不足するまでの間、実セカンダリ圧を上昇させ、実セカンダリ圧Psecから必要となる差推力を得るため
