Description
Tra=Tma・ηP …(1)
逆に、領域2と領域3の交点Bにおける電気モータのトルク出力Tmb(ロールモーメント換算)と慣性力(横加速度)に起因するロールモーメントTrbとの均衡は、領域3は、電気モータMが車体慣性力によってねじり戻される領域3であるため、次の式(2)となる。
Tmb=Trb・ηN …(2)
Trb=Tra/(ηP・ηN) …(3)
ここで、車体慣性力に起因するロールモーメントは、概ね横加速度と比例関係にあるため、式(3)から、点A及びBにおける横加速度を夫々Ga及びGbとすると、次の式(4)の関係が導かれる。
Gb=Ga・{1/(ηP・ηN)} …(4)
Gye =(Vx2・δf)/{L・N・(1+Kh・Vx2)}…(5)
ここで、Lはホイールベース、Nはステアリングギア比、Khはスタビリティファクタである。
Rmv =K1・Gye+K2・dGye+K3・Gy+K4・dGy …(6)
上記のように、制御演算の遅れやアクチュエータの応答性を補償するために、ハンドル角δfと車速Vxから求められる演算横加速度Gyeとその変化量dGyeが考慮される。
