Abstract

L’invention porte sur un procédé de gestion d'une décélération d'un véhicule automobile comportant: - une étape d'acquisition d'un déplacement (D) d'une pédale de freinage, - une étape d'acquisition d'une décélération (Dec_veh) du véhicule automobile, - une étape de vérification que le couple formé par le déplacement (D) de la pédale de freinage et la décélération (Dec_veh) correspondante se trouve dans une zone de freinage efficace (Zeff), - et dans le cas où le couple formé par le déplacement (D) de la pédale de freinage et la décélération (Dec_veh) correspondante ne se trouve pas dans la zone de freinage efficace (Zeff), ledit procédé comporte une étape d'activation du dispositif de modulation de pression de façon à produire une décélération (Dec_veh) du véhicule automobile se situant au minimum sur la courbe d'activation (C_act).
