A tire-road model for fast grip potential estimation

Résumé

This paper presents a novel model of tire-road contact forces intended for fast grip potential estimation. Here, grip potential is defined as the reachable peak of friction provided by a given tire-road contact. The proposed model is written in such a way that grip potential and slip-ratio at grip potential appear both explicitly into the model description. The model is intended for fitting experimental data into the range of zero slip-ratio and grip potential, and by consequence it requires a few number of parameters to be tuned. A parameter estimation process using the proposed model has been implemented and compared with trajectories generated by a Pacejka’s model, for illustrating the advantages and limitations of the proposed model. In addition, a parameter estimation has been also performed by using real-data, obtained from a flat track tire testing machine, to illustrate the performance of the model for grip potential estimation, in presence of noisy and small amounts of data.
