It has been shown recently that the tire-ice friction is characterized by a significant dynamic potential for abrupt increases of wheel torque at low vehicle speeds. The paper presents experimental identification and modeling of dynamic tire friction potential (DTFP) on ice surfaces. The model is based on the LuGre tire friction model extended with the DTFP effect. The extension is based on the hypothesis that the DTFP is caused by the bristle dwell time effect. The bristle dwell time process is firstly described by a distributed-parameter model, which is then transformed to a lumped-parameter form based on a definition of average tire-bristle dwell time. The calculated bristle dwell time is used to schedule the maximum static friction parameter of the LuGre model. The extended tire friction model is validated against the experimental data for different operating conditions.
