Abstract
L'invention concerne un système de freinage (1) pour véhicule automobile, comprenant : - deux actionneurs (11, 12), adaptés à produire une pression dans un circuit de freinage hydraulique (70), et - une unité de commande (40), adaptée à élaborer des consignes de freinage (Cf) pour lesdits deux actionneurs. Selon l'invention, l'unité de commande est adaptée à systématiquement transmettre la même consigne de freinage aux deux actionneurs, il est prévu au moins un capteur (23) adapté à mesurer la valeur d'un paramètre de freinage (Acc), et un premier des actionneurs comprend un calculateur (32) qui est adapté à déterminer une valeur cible pour le paramètre de freinage en fonction de ladite consigne de freinage, et à calculer une consigne corrigée (Cfc2) en fonction de la différence entre la valeur mesurée et la valeur cible du paramètre de freinage.
