Identification of tire model parameters from vehicle measurements using sensitivity analysis
Résumé
Vehicle handling performance simulation is subject to many different tire models existing to estimate tire lateral forces. However, even with complex and accurate vehicle/tire models, significant differences appear between actual measurements of vehicle performance and simulation results. The non-consideration of actual operating conditions such as tire/road temperatures when using empirical tire models could be a significant contributor to these observations. A solution envisaged to reduce these differences is to identify new tire model parameters directly from vehicle track tests and to make a comparison with the parameters identified from indoor bench testing.
