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.The invention relates to a braking system (1) for a motor vehicle, comprising: - two actuators (11, 12), adapted to produce pressure in a hydraulic braking circuit (70), and - a control unit (40) , adapted to develop braking instructions (Cf) for said two actuators. According to the invention, the control unit is adapted to systematically transmit the same braking instruction to the two actuators, there is provided at least one sensor (23) adapted to measure the value of a braking parameter (Acc), and a first of the actuators comprises a computer (32) which is adapted to determine a target value for the braking parameter as a function of said braking setpoint, and to calculate a corrected setpoint (Cfc2) as a function of the difference between the measured value and the target value of the braking parameter.
