Abstract
Description
クラッチ入力軸回転数理論値=A{V・cos(δ−β)+γ・Lf・sinδ}
クラッチ出力軸回転数理論値=B・V・cos β
引算器72で算出される回転差(ΔN)目標値は、
回転差(ΔN)目標値=クラッチ入力軸回転数理論値−クラッチ出力軸回転数理論値
である。
修正後の配分比=(1−BDR)DNR+BDR
と表せる。ここで、回転差制御量DNRは、絶対値1以下の小数値であるから、「修正後の配分比」は、1以下の値であり、総駆動力に対応する配分比「1」を上回らないように調整することができる。
修正後の配分比=(1−BDR)DNR+BDR
は、「0.82」となり、総駆動力に対応する配分比「1」を上回らないように調整され、タイトコーナーブレーキング現象が防止される。
