Abstract
In this paper the energetic dynamic model of the tire-ground interaction in a vehicle is presented and a comparison with the LuGre friction model is given. The Power-Oriented Graphs (POG) technique is exploited for both representing and analyzing the two dynamic systems. In particular the LuGre model is analyzed showing some drawbacks and a modified model is proposed in order to guarantee dissipativity. Simulation results end the paper comparing the two dynamic models of the tire-ground interaction.
