Abstract

Une unité de commande de freinage d'urgence autonome (AEB) (S1) réalise un actionnement autonome d'un système de freinage de véhicule (3) dans le cas où une stratégie de décision génère une requête d'évitement de collision par freinage (étape S2). Ultérieurement, une unité de commande de dispositif électronique de stabilité programmé (ESP) (52) provoque un changement dans une carte utilisée pour une commande de la répartition de force de freinage électronique (EBD) en remplaçant une première carte de répartition de force de freinage (La1, Lb1) par une seconde carte de répartition de force de freinage (La2, Lb2) (étape S3). L'unité de commande ESP (52) réalise la commande EBD sur la base de la seconde carte de répartition de force de freinage (La2, Lb2). À l'étape S4, l'unité de commande ESP réalise une commande de la répartition de force de freinage.An autonomous emergency braking control unit (AEB) (S1) realizes autonomous actuation of a vehicle braking system (3) in the event that a decision strategy generates a brake collision avoidance request ( step S2). Subsequently, a programmed electronic stability device (ESP) control unit (52) causes a change in a board used for electronic brake force distribution (EBD) control by replacing a first brake force distribution board (La1, Lb1) by a second braking force distribution map (La2, Lb2) (step S3). The ESP control unit (52) performs EBD control based on the second brake force distribution board (La2, Lb2). In step S4, the ESP control unit performs brake force distribution control.
