Abstract

The purpose of this paper is the correlation research between objective tire parameters and subjective test driver evaluations. On the one hand, the test driver evaluates subjectively the tire in a freely chosen situation. On the other hand, the tire physical characteristics are measured objectively. This contribution consists in the determination of objective tire parameters which are responsible for the ratings given by the test driver. Then, these parameters are fused thanks to the Choquet integral aggregation tool. In the frame of this study, four objective tires parameters, based on the well-known Pacejka model, have been determined. Finally, this paper illustrates that these parameters can be satisfactorily correlated with the subjective ratings of the observed handling performances of the tire.
