METHOD AND DEVICE FOR DETERMINING TIRE WEARS

A computer-implemented method for determining a wear indicator (W*) of a tire of a vehicle (VEH) so-called test vehicle based on driving states (DS) of said test vehicle during a time period, said method comprising steps of: • determining (S10) at least one statistical representation (HIST) of said driving states over said time period; • determining (S20) at least one parametrized function (FP, FP) representative of said at least one statistical representation; and • determining (S30) said wear indicator with an estimation model (PM) taking as input at least one parameter (A, B, A, B) of the at least one parametrized function.
