A Semi-Empirical Tire-Model for Transient Combined-Slip Forces

This paper presents a semi-empirical combined-slip tiremodel including transient behavior. The method relies on theassumption that the transient behavior is a result from the dynamicdeformation of the tire carcass and that the interaction between thelateral and longitudinal slip and forces can be explained by thedeformation of the rubber treads. The deformation of the tire carcassmakes the tread slip deviate from the wheel-rim motion in a way thatmay be described by differential equations. A method based onbrush-model tire mechanics is used to construct the combined-slipforces as nonlinearscalings of corresponding pure-slip forces
