Abstract
(DE)
Die vorliegende Erfindung betrifft eine elektromechanisch betätigbare Feststellbremse für Kraftfahrzeuge mit mindestens einem elektromechanischen Aktuator, dessen Rotationsbewegung von einer Betätigungseinheit in eine Translationsbewegung umgesetzt wird und wenigstens ein Bremsglied derart verschiebt, dass mindestens ein mit dem Bremsglied verbundener Bremsbelag mit einer Feststellkraft gegen einen mit einem Kraftfahrzeugrad fest verbundenen Rotor gepresst wird, wobei beim Zuspannen und/oder Lösen der Feststellbremse, die Stromaufnahme des elektromechanischen Aktuators ermittelbar ist. Außerdem betrifft die Erfindung ein Verfahren zum Betrieb der elektromechanisch betätigbaren Feststellbremse. Bei der vorliegenden Erfindung sind Mittel vorgesehen, die die Stromaufnahme des elektromechanischen Aktuators derart verändern, dass vorab bestimmte Werte der Feststellkraft ermittelbar sind. Diese Mittel sind derart ausgebildet, dass sie eine signifikante Änderung der Stromaufnahme des elektromechanischen Aktuators beim Zuspannen oder beim Lösen der Feststellbremse bewirken, die auf einen vorab bestimmten Wert der Feststellkraft schließen lässt.
(EN)
The present invention relates to an electromechanically operable parking brake for motor vehicles with at least one electromechanic actuator, the rotor movement thereof being transformed by an actuating device in a translational motion and moving at least one brake member in such a way as that at least one brake lining connected to the brake member is pressed against a rotor connected tightly to a motor vehicle wheel by a locking force, wherein the current consumption of the electromechanic actuator can be determined by tightening and/or releasing the parking brake. The invention further relates to a method for the operation of the electromechanically operable parking brake. The present invention provides means by changing the current consumption of the electromechanic actuator is such a way, that certain values of the locking force can be determined beforehand. Said means are in such a manner, that a significant change of the current consumption of the electromechanic actuator, when tightening or releasing of the parking brake, is achieved. Said change draws conclusion to an earlier determined value of the locking force.

La présente invention concerne un frein à main pour véhicule actionnable de manière électromécanique avec au moins un vérin électromécanique, dont le mouvement de rotation est converti en un mouvement de translation par une unité de commande et déplace au moins un membre de freinage de sorte qu'au moins une garniture de frein reliée au membre de freinage est comprimée avec une force d'arrêt contre un rotor relié fermement à une roue de véhicule, l'absorption de courant du vérin électromécanique pouvant être déterminée lors du serrage et/ou du desserrage du frein à main. La présente invention concerne également un procédé d'actionnement du frein à main actionnable de manière électromécanique. Selon la présente invention sont prévus des moyens qui modifient l'absorption de courant du vérin électromécanique de telle sorte qu'il est possible de déterminer des valeurs prédéfinies de la force d'arrêt. Ces moyens sont formés de telle sorte qu'ils causent une modification importante de l'absorption de courant du vérin électromécanique lors du serrage ou du desserrage du frein à main, qui révèle une valeur prédéfinie de la force d'arrêt.
