Abstract

Ce procédé commande un système de frein (2) de véhicule automobile. Ce système de frein (2) comporte une première chaîne de commande (6) de frein en roulage du véhicule, reliée à un organe de serrage (24) du frein (4), et une seconde chaîne de commande (8) de frein pour stationnement du véhicule, reliée à l’organe de serrage du frein (24). Cette seconde chaîne de commande (8) comporte une unité de commande électronique (15) pilotant l’organe de serrage (24) du frein (4). Lors d’une étape de commande de freinage, si l’on détecte une défaillance du système de frein, on applique une étape de commande de secours prenant en compte la valeur d’un paramètre d’état d’un organe de référence (16, 18) de la première chaîne de commande (6) de frein. En outre, si l’on détecte des défaillances (30, 40) à la fois dans les première (6) et seconde (8) chaînes de commande, lors de l’étape de commande de secours, on transmet la valeur du paramètre d’état de l’organe de référence (16, 18) à l’unité de commande électronique (15) qui en déduit une force de serrage pour piloter l’organe de serrage (24) du frein (4).
