Validation of a basic combined-slip tyre model for use in friction estimation applications

Abstract

Tyre modelling is an important part of understanding and estimating the tyre–road friction. In this paper a basic steady-state tyre model for the combined-slip case is derived. The model is intended to be used in friction estimations applications, where the model complexity is of high priority. The model, described using only two parameters, is validated with measured data from various conditions and tyre types using mobile measurement equipment. The performance from the measurements suggests that only two parameters are sufficient for the combined-slip case.
