Abstract

In this paper, to analyse rider’s effects on the motion of a motorcycle, we model a rider-motorcycle system taking account of the leaning motion of the rider’s upper torso and the rider’s arm. In addition, the nonlinearity of the tire force is introduced to the tire model taking account of the cross-sectional shape, the elastic deformation and the tire-ground contact area. On the basis of the derived nonlinear state-space model, we analyse the effects of not only the rider’s arm but also his/her postures in steady-state turning by simulations. The rider’s postures of lean-with, lean-in, and lean-out are realized by adding the lean torque to the rider’s upper torso. The motorcycle motion and the rider’s effects are analysed in the case where the friction coefficient of the road surface changes severely in the steady-state turning. Also, the linearised steady-state turning model is derived, and the stability analysis of the motorcycle in the steady-state turning is performed.
