Abstract
(DE)
Verfahren zum Betrieb einer Bremsanlage für ein Kraftfahrzeug mit hydraulisch betätigbaren Radbremsen (8a-8d), einem mittels eines Bremspedals (1) betätigbaren Hauptbremszylinder (2), wobei der Hauptbremszylinder (2) über ein Trennventil (23) mit einer Bremsversorgungsleitung (13) trennbar verbunden ist, an welche die Radbremsen (8a-8d) angeschlossen sind, einer Simulationseinrichtung (3), welche mit dem Hauptbremszylinder (2) hydraulisch verbunden ist, wobei die Simulationseinrichtung (3) mittels eines Simulatorfreigabeventils (32) zu- und abschaltbar ist, und einer elektrisch steuerbaren Druckbereitstellungseinrichtung (5), wobei die Druckbereitstellungseinrichtung (5) mit der Bremsversorgungsleitung (13) verbunden ist, wobei bei einer Bremspedalbetätigung durch einen Fahrer ein Sonderdruckstellverfahren durchgeführt wird, bei welchem die Druckbereitstellungseinrichtung (5) mit dem Hauptbremszylinder (2) und zumindest einer der Radbremsen verbunden wird und mittels der Druckbereitstellungseinrichtung (5) ein vorbestimmter Drucksollwert (Psyssoll) in dem Hauptbremszylinder (2) eingeregelt wird, sowie Bremsanlage, in welcher ein solches Verfahren durchgeführt wird.
(EN)
The invention relates to a method for operating a brake system for a motor vehicle, comprising hydraulically actuatable wheel brakes (8a - 8d), a master brake cylinder (2) actuatable by a brake pedal (1), wherein the master brake cylinder (2) is detachably connected by a separating valve (23) to a brake supply line (13) on which the wheel brakes (8a, 8d) are connected, and a simulation device (3) which is hydraulically connected to the main brake cylinder (2), said simulation device (3) can be switched on and off by means of a simulator release valve (32). Also comprising an electrically controllable pressure supply device (5) which is connected to the brake supply line (13). A special pressure-regulating method is carried when a brake pedal is actuated by a driver, in which the pressure supply device (5) is connected to the master brake cylinder (2) and to at least one of the wheel brakes and a predetermined pressure desired value (Psyssoll) is controlled in the master brake cylinder (2) using the pressure supply device (5). The invention also relates to a brake system which carries out said method.

L'invention concerne un procédé pour faire fonctionner un système de freinage pour véhicule automobile comprenant des freins de roue à actionnement hydraulique (8 a-8d), un maître-cylindre (2) pouvant être actionné au moyen d'une pédale de frein (1), ce maître-cylindre (2) étant relié de manière séparable par l'intermédiaire d'une vanne de séparation (23) à une conduite d'alimentation de frein (13) à laquelle sont raccordés les freins de roue (8a-8d), un dispositif de simulation (3) qui est relié hydrauliquement au maître-cylindre (2), ce dispositif de simulation (3) pouvant être mis en circuit et hors circuit au moyen d'une soupape de libération de simulateur (32), ainsi qu'un dispositif générateur de pression (5) à commande électrique, ce dispositif générateur de pression (5) étant relié à la conduite d'alimentation de frein (13). Lors d'un actionnement de la pédale de frein par un conducteur, un procédé de réglage de pression particulier est mis en oeuvre, selon lequel le dispositif générateur de pression (5) est relié au maître-cylindre (2) et à au moins un des freins de roue, et une valeur de consigne de pression (Psyssoll) prédéfinie est réglée dans le maître-cylindre (2) au moyen du dispositif générateur de pression (5). L'invention concerne également un système de freinage dans lequel un tel procédé est mis en oeuvre.
