Abstract:

Tire is the only link between tire and road, which provides all force and moments for vehicle motion
including driving, steering and braking. Tire mechanics is the base for vehicle dynamics, which progress
depends on to a large extent the precise tire dynamical model. This paper reviews the state of the art for tire
dynamical models, including handing tire model, ride comfort model, and durability load simulation model. The
advantages and disadvantages for three tire modeling approaches, i.e. simple physics based, empirical based
and structure based, are compared. It can be concluded that the fufure of the tire model lies in the so called
advanced tire model, i.e. structure based model will gain more advances and interest in both academics and
industries, the tire dynamical model will be integrated with vehicle dynamics simulation and vehicle active safety
system development. The vehicle-tire-road indication theory will be ultimate goal of the research.

Key words: tire dynamical model, vehicle dynamics simulation, durability load simulation, advanced tire model, vehicle-tire-road interaction theory
