Experimental analysis and modeling of longitudinal tire friction dynamics for abrupt transients

A test vehicle has been used to collect experimental data related to abrupt engine throttle tip-in transients. The data point to significant dynamic potential of longitudinal tire friction force on ice surface. Such a behavior cannot be predicted by using the available brush-type dynamic tire friction models. Based on the results of experimental and simulation analyses, the LuGre tire friction model is extended to predict the dynamic friction potential. The extended model is validated against the experimental data.
