This study, carried out in cooperation with ESSAIM, Ecole Supérieure des Sciences Appliquées pour l'Ingénieur, Mulhouse in France, was aimed at developing accurate mathematical models of some types of tyre, in order to analyze their influence on vehicle dynamics. The complete vehicle was studied under dynamic conditions, to quantify the influence of all factors, such as rolling forces, aerodynamic forces and many others, acting on their components on torque distribution and vehicle dynamics. Mathematical models for two common types of vehicle, namely front and rear wheel drive, each ones equipped with the different types of tyre, were developed. Both models were used to simulate the behaviour of a real vehicle, developing complete simulation software, developed in Matlab-Simulink environment at MIPS, Modélisation Intelligence Processus Systèmes. Therefore, this car model, running on a straight and curve track, was also developed, to get a qualitative insight of the influence of these kinds of interactions on traction capabilities. The software, used to simulate some dynamics manoeuvres, shows up the basic behaviour of vehicle dynamics.
