Description
Die Erfindung betrifft ein Druckmittelbehälter mit einer Behälterwarnvorrichtung, insbesondere für ein hydraulisches Kraftfahrzeug-Bremssystem. In Kraftfahrzeugen werden vielfach Druckmittelbehälter eingesetzt, deren Inhalt mithilfe Behälterwarnvorrichtung überwacht wird. Eine stets verfügbare Funktionsfähigkeit ist für sicherheitsrelevante Systeme wie hydraulische Bremssysteme eminent, daher muss der Füllstand in dem Druckmittelbehälter besonders zuverlässig und mit einer hohen Ausfallsicherheit überwacht werden muss.The invention relates to a pressure medium container with a container warning device, in particular for a hydraulic motor vehicle brake system. In motor vehicles, pressure medium containers are often used, the contents of which are monitored by means of a container warning device. An always available functionality is eminent for safety-relevant systems such as hydraulic brake systems, therefore the level in the pressure fluid container must be monitored particularly reliably and with a high degree of reliability.
Stand der TechnikState of the art
Die Verfügbarkeit von ausreichender Menge an Druckflüssigkeit in einem hydraulischen Bremssystem ist eine unbedingte Voraussetzung für eine sichere Bremsung. Zu einer genauen Ermittlung von Füllstand in dem Druckmittelbehälter sowie einer effektiven Verarbeitungs- und Übertragungsmöglichkeit der gewonnenen Informationen an Regelungs- und Steuerungssysteme des Fahrzeugs verwenden die meisten bekannten Behälterwarnvorrichtungen elektrische und elektronische Messmethoden, welche insbesondere Veränderungen von Strom und/oder Spannung registrieren und verfügen dementsprechend über Komponententräger mit den daran angeordneten elektrischen und/oder elektronischen Schaltungen und elektrischen Komponenten wie empfindliche Messwiderstände, die oft durch gesonderte Widerstände vor Beschädigungen durch Überlastung geschützt werden müssen, sogenannte Schutzwiderstände. Die Zuverlässigkeit vorgenannter Schaltungen und Komponenten hinsichtlich einer stabilen Leistungsfähigkeit sowie Ausfallsicherheit wird jedoch in einer spezifischen fahrzeugtypischen Umgebung, die sich durch ständige weite Temperaturänderungen, hohe Vibrationen, Stoßbelastungen und Spannungsschwankungen im elektrischen Bordsystem auszeichnet, insbesondere in sicherheitsrelevanten Bereichen wie Überwachung von Bremssystemen oft als weiterhin verbesserungswürdig angesehen.The availability of sufficient pressure fluid in a hydraulic brake system is an absolute requirement for safe braking. For a precise determination of level in the pressure fluid container and an effective processing and transmission of the information obtained to control and control systems of the vehicle most known container warning devices use electrical and electronic measuring methods, which register in particular changes in current and / or voltage and have accordingly Component carrier with the arranged thereon electrical and / or electronic circuits and electrical components such as sensitive measuring resistors, which often have to be protected by separate resistors from damage due to overloading, so-called protective resistors. However, the reliability of the aforementioned circuits and components in terms of stable performance and reliability is still in a specific vehicle environment, which is characterized by constant wide temperature changes, high vibration, shock loads and voltage fluctuations in the onboard electrical system, especially in safety-related areas such as monitoring of braking systems often still in need of improvement considered.
Aufgabe:Task:
Es besteht daher die Aufgabe, einen Druckmittelbehälter mit einer erhöhten Ausfallsicherheit der Behälterwarnvorrichtung anzubieten.It is therefore an object to offer a pressure fluid container with increased reliability of the container warning device.
