Description
Die Erfindung betrifft eine zweikreisige Kraftfahrzeugbremsanlage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a dual-circuit motor vehicle brake system according to the preamble of
Aus der Patentschrift
Die Aufgabe der Erfindung wird nunmehr darin gesehen, eine hydraulische Kraftfahrzeugbremsanlage der eingangs genannten Gattung hinsichtlich des Befüllprozesses dahingehend zu optimieren, dass unter Beibehaltung des für die hydraulische Kraftfahrzeugbremsanlage notwendigen Aufbaus eine möglichst schnelle Befüllung der Bremskreise mit Bremsflüssigkeit erfolgt.The object of the invention is now seen to optimize a hydraulic motor vehicle brake system of the type mentioned in terms of the filling process to the effect that while maintaining the necessary structure for the hydraulic motor vehicle brake as fast as possible filling the brake circuits with brake fluid.
Diese Aufgabe wird erfindungsgemäß für eine Kraftfahrzeugbremsanlage der genannten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. This object is achieved for a motor vehicle brake system of the type mentioned by the characterizing features of
Weitere Merkmale der Erfindung sind den einzelnen Patentansprüchen als auch aus der Beschreibung eines Ausführungsbeispiels zu entnehmen.Further features of the invention can be taken from the individual claims as well as from the description of an embodiment.

Vor einer blasenfreien Befüllung der hydraulischen Kraftfahrzeugbremsanlage mit Bremsflüssigkeit erfolgt ein Evakuierungsprozess jedes Primärkreises, der jeweils die hydraulischen Bremskreisabschnitte eines jeden Bremskreises umfasst, welcher sich vom Bremsdruckgeber
Dem Evakuierungsprozess und einer empfohlenen Vakuumleckprüfung folgt zweckmäßigerweise eine nochmalige Evakuierung, an die sich der erfindungsgemäße Befüllprozess jedes Primärkreises mit entgaster Bremsflüssigkeit anschließt. Im Einzelnen sind erfindungsgemäß zur Befüllung jedes Bremskreises mit Bremsflüssigkeit über jeden Hauptzylinderanschluss
Diese Befüllroutine kann nach der Fertigstellung der Bremsanlage im Kraftfahrzeug am Bandende beim Fahrzeughersteller unter Zuhilfenahme eines externen, der Befüllmaschine zugehörigen Steuergeräts, das entsprechend programmiert ist, als auch mittels eines im Kraftfahrzeug verbauten Bremsdrucksteuergeräts ausgeführt werden. Erfolgt die Befüllroutine über das Bremsdrucksteuergerät, so kann nach Beendigung des Befüllprozesses vorteilhaft mittels des Bremsdrucksteuergeräts gleichzeitig eine sichere Überwachung des zulässigen Systemdrucks in der Bremsanlage erfolgen. This Befüllroutine can be performed after the completion of the brake system in the motor vehicle at the end of the tape at the vehicle manufacturer with the help of an external, the filling machine associated control unit, which is programmed accordingly, as well as by means of a built-in motor vehicle brake pressure control unit. If the filling routine is carried out via the brake pressure control unit, it is advantageously possible after the filling process has ended to advantageously monitor the permissible system pressure in the brake system by means of the brake pressure control unit.

Das als Rechteckimpulse dargestellte Puls-/Pausenverhältnis der elektromagnetisch erregten Umschalt- und Auslassventile ESV, NC FL, NC FR hat überdies den Vorteil, dass im Sinne einer möglichst vollständigen Einlagerung von eventuell noch vorhandenen Lufteinschlüssen in der Bremsflüssigkeit ein Zerhacken und eine bessere Auflösung der eventuell noch vorhandenen Lufteinschlüsse im Bremsflüssigkeitsvolumen im Sinne eines Absorptionsprozesses gefördert wird. Durch die Verwendung von Bremsflüssigkeit, die hinsichtlich des Luftgehalts untersättigt ist, vermag die Bremsflüssigkeit im Rahmen des Absorptionsprozesses das Luftvolumen aufzulösen und in sich blasenfrei einzulagern.The pulse / pause ratio of the electromagnetically excited change-over and exhaust valves ESV, NC FL, NC FR shown as rectangular pulses has the further advantage that in the sense of a complete storage of possibly existing air bubbles in the brake fluid chopping and better resolution of possibly still existing air pockets in the brake fluid volume in the sense of an absorption process is promoted. Due to the use of brake fluid, which is undersaturated in terms of air content, the brake fluid is able to dissolve the air volume as part of the absorption process and to store it in a bubble-free manner.
