Description
Gmax=(Freq-Fload)/W …(1)
なお、上式(1)におけるFloadは、走行抵抗を示しており、この走行抵抗は、路面と車輪との転がり摩擦抵抗や、空力抵抗などの車両1の推進力に対抗した荷重であり、車速に基づいて算出することができる。また、Wは、車両1の総重量であって、サスペンションの変位量などから求めてもよく、所定の重量を積載しているものと仮定した重量に設定してもよい。この到達加速度Gmaxが、この発明の実施形態における「目標加速度」に相当する。
Jwout=((Gmax-Gcurrent)×Jopt)/(Gwout-Gcurrent) …(3)
なお、上式(3)における(Gmax-Gcurrent)×Jopt)が、この発明の実施形態における「基準刺激強度」に相当し、上式(3)における(Gwout-Gcurrent)とJwoutとの積が、この発明の実施形態における「要求刺激強度」に相当する。
