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.Commands (38, 41) for controlling the movement of an electro-mechanical brake actuator, operating as an emergency brake while driving the vehicle, are provided to alternately apply and re-tighten the brake as a function of a speed difference ( Δω) between the wheel fitted with the brake and another wheel. The release commands (38) are interrupted as soon as the intensity value (I) of the electric current driving the actuator stabilizes, in order to avoid empty strokes of the actuator and to allow rapid tightening afterwards. Figure for abstract: Figure 5.
