Abstract:
1. A system for controlling the stability of a vehicle having wheels, including means for imparting a longitudinal force to a tire intended to roll on the ground, means for modulating the longitudinal force, and comprising a controller using at least a slip parameter G Opt corresponding to a predetermined value of a coefficient of friction μ, the system including means for performing the following operations: (a) on each activation of the means for imparting a longitudinal force to the tire, for at least two different levels “i” of the longitudinal force each corresponding to one slip G (b) determining a slope α (c) calculating coefficients A (d) calculating the optimum slip G (e) acting on the means for imparting a longitudinal force to the tire so as to maintain the slip at optimum value G
