Abstract

L'invention concerne un système de freinage (100), comprenant un actionneur de frein primaire (1) et un actionneur de frein secondaire (2), une pression de freinage cible (p_target) devant être réglée (603) au moyen de l'actionneur de frein primaire. Dans une première phase de surveillance, l'actionneur de frein secondaire (2) surveille (604) l'actionneur de frein primaire (1) pour vérifier si la pression de freinage cible est présente. Si la pression de freinage cible n'est pas présente, l'actionneur de frein secondaire (2) déconnecte hydrauliquement (605) au moins une connexion hydraulique (22) entre l'actionneur de frein primaire et secondaire (1, 2).
