ABSTRACT:
Vehicle stability control system, the system including means for imparting a longitudinal force on the tire and means for calculating the slip parameter GOptat each activation of the means for imparting a longitudinal force on the tire in the following manner: as the values of Giare acquired, calculating the variation in G with respect to time, as long as the variation is above a low threshold, calculating coefficients A[wet, p]by direct calculation or by an appropriate regression so as to model variation in G with respect to time by a variation curve which is a function of (Gi, A[wet, p]), as soon as the variation is greater than a high threshold, determining a target slip GCwetusing at least the last values of A[wet, p].
