TIRE FRICTION MODELS AND THEIR EFFECT ON SIMULATED VEHICLE DYNAMICS

In this paper, various tire friction models are examined and their similarities and differences are pointed out. Emphasis is placed on the tire side force and a numerical comparison is illustrated based on existing experimental data. Different uses of the friction ellipse are discussed. The sensitivity of vehicle response to different tire models is studied using a nonlinear, simplified vehicle model. Three basic maneuvers are simulated: cornering, straight ahead braking and braking in a turn. The simulation results are compared with one particular set of simulations in which the tire forces are specified by tables of experimental tire data. Accuracies and computing times for each tire model are studied.
