Abstract

Le dispositif de serrage de frein de stationnement électro-mécanique comporte un module de mesure du courant électrique alimentant le moteur électrique, pour estimer continuellement la force de serrage du frein. La stratégie de serrage comporte plusieurs commandes (27, 29), dont les commandes de resserrage (29) ont des durées variables et cessent seulement quand une valeur de force de serrage a été atteinte. Figure pour l’abrégé : Figure 6.The electro-mechanical parking brake application device includes a module for measuring the electric current supplying the electric motor, to continuously estimate the brake application force. The tightening strategy comprises several commands (27, 29), of which the tightening commands (29) have variable durations and only stop when a tightening force value has been reached. Figure for abstract: Figure 6.
