Abstract

Selon un procédé de détermination de l'obliquité αi et/ou de la stabilité latérale Fs d'un véhicule freiné, on détermine les valeurs recherchées en tant que valeurs estimatives à partir d'un modèle simplifié du véhicule, en utilisant les vitesses des roues VRi, l'angle de braquage δ, la vitesse d'embardée σ et la pression PHB2 dans le maître-cylindrique de freinage ou les pressions Pi de freinage des roues en tant que valeurs de mesure.
