Abstract

Des commandes (38, 41) de commande de mouvement d’un actionneur de frein électro-mécanique, fonctionnant en frein de secours durant la conduite du véhicule, sont fournies pour alternativement serrer et resserrer le frein en fonction d’une différence de vitesse (Δω) entre la roue qu’équipe le frein et une autre roue. Les commandes de relâchement (38) sont interrompues dès que la valeur d’intensité (I) du courant électrique entraînant l’actionneur se stabilise, afin d’éviter des courses à vide de l’actionneur et de permettre des resserrages rapides ensuite. Figure pour l’abrégé : Figure 5.
