METHOD FOR ESTIMATING THE PERFORMANCE OF A TYRE IN BRAKING CONDITIONS

摘要

The invention relates to a method for estimating, in braking conditions, the performance of a tyre to be fitted on a vehicle, the method including an experimental phase (EXPERIM) including at least one evaluation step (EVAL_MU) of the adhesion coefficient (µ) of the tyre on the ground. According to the invention, the evaluation step is carried out for different values (Vi) of the relative movement speed of the tyre axis relative to the ground and for different values (gi%) of the sliding rate of the tyre on the ground, wherein the experimental phase (EXPERIM) further includes the step of modelling (MODEL) that comprises representing the adhesion coefficient of the tyre so that the evaluation step (EVAL__MU) results in a function (MU3D) of the relative movement speed of the tyre axis relative to the ground and of the sliding rate of said tyre on the ground.
