Description
遠心力G=(車重m*車速V^2)/旋回半径R・・・(式1)
ここで、旋回半径Rは、道路データ内に含まれる値を参照する。車重mと車速Vは、車両状態検出センサ26の出力から得ることができる。
ロール量MR=遠心力G*h・・・(式2)
変速段のエンジンブレーキ量=(力1)+(力2)+(力3)・・・(式3)
(力2):転がり抵抗力=μ*W*cosθ
(力3):空気抵抗力=1/2*ρ*CD*S*(V/36)^2
なお、「μ」は摩擦係数、「W」は荷重、「ρ」は空気密度、CDは空気抵抗計数、「S」は前面投影面積、「V」は速度を示す。
第2必要エンジンブレーキ量=車重m*(ΔV/Δt)・・・(式4)
