Vehicle stability control system with an algorithm for estimation of the rate of change of a representative parameter

摘要

System for controlling the stability of a vehicle, the system comprising means for printing on the tire, a longitudinal force and means for calculating the parameter sliding gopt during each activation means for printing on the tire, a longitudinal force of the following manner: during the acquisition of the values of g i, to calculate the variation in g with respect to time, as long as said variation is greater than a low threshold, to calculate the coefficients [wet, p] direct calculation or by a suitable regression in order to model the variation in g with respect to time by a curve of variation which is a function of (gi, [wet, p]), as soon as said variation is greater than a high threshold, to determine a target slip gcwet by using at least the last values of a [wet, p].
