Description
Die Erfindung betrifft Systeme zur Diagnose von Telematiksystemen. Insbesondere betrifft die Erfindung Testsysteme zur Überprüfung der Funktionalität von Telematikeinrichtungen in Fahrzeugen, die auch für den mobilen Einsatz geeignet sind.The The invention relates to systems for diagnosing telematics systems. Especially The invention relates to test systems for checking the functionality of telematics devices in vehicles that are also for suitable for mobile use.
Moderne Fahrzeuge sind mit einer Vielzahl von elektronischen Einrichtungen ausgestattet, wobei Radio, Kommunikations- und Sensorsysteme zu Telematikfunktionen über entsprechende Schnittstellen zusammengeführt sind.modern Vehicles come with a variety of electronic devices equipped with radio, communication and sensor systems to telematics functions via appropriate Interfaces merged are.

Komponenten sind bekannt. In der
Für eine Überprüfung aller wesentlichen Funktionen komplexer Telematikeinrichtungen werden weitergehende Testsysteme für Produktion und Service benötigt. Diese leistungsfähigen Testsysteme sollen es ermöglichen, die einwandfreie Funktion der drahtlosen Kommunikations- und Sensorsysteme mit geringem Aufwand, kurzen Messzeiten und in der normalen Fertigungs- und Serviceumgebung zu testen. Dabei soll es möglich sein, das vollständige Telematiksystem eines Fahrzeugs einschließlich der Funktion vorhandener Antennen zu diagnostizieren.For a review of all essential functions of complex telematics equipment advanced test systems for Production and service needed. This powerful Test systems should make it possible the proper functioning of the wireless communication and sensor systems low effort, short measurement times and in the normal manufacturing and service environment to test. It should be possible be, the whole Telematics system of a vehicle including the function of existing To diagnose antennas.
Insbesondere die Einbeziehung der Antennen in die Messungen bereitet bei bisherigen Testsystemen Probleme. In normalen Fertigungs- und Serviceumgebungen, z.B. Fertigungs- und Montagehallen, werden Funkstrecken durch vielfache Reflexionen und auch durch Abschattungen derartig gestört, dass eine aussagekräftige Vermessung von Funkübertragungsstrecken nicht möglich ist. Üblicherweise werden daher für eine messtechnische Charakterisierung der Antennensysteme die Messungen in einem reflektionsfreien Raum durchgeführt. Reflexionsfreie Räume in denen komplette Fahrzeuge vermessen werden können, haben aber einen erheblichen Raumbedarf und stellen auch eine hohe Investition dar. Darüber hinaus ist eine Einbeziehung solcher reflektionsarmen Räume in Fertigungsstraßen nicht praktikabel, und auch für Servicebetriebe können derartig hohe Investitionen nicht in Betracht gezogen werden. Eine mobile Telematikdiagnose erfordert kostengünstige Systeme, die mit geringem Aufwand in bestehende Produktions- und Serviceumgebungen integriert werden können.Especially the inclusion of antennas in the measurements prepares in previous Test systems problems. In normal manufacturing and service environments, e.g. Production and assembly halls, radio links are multiples Reflections and also so disturbed by shading that a meaningful Measurement of radio transmission links not possible is. Usually therefore for a metrological characterization of the antenna systems the measurements performed in a reflection-free room. Reflection-free spaces in which complete vehicles can be measured but have a significant Space requirements and also represent a high investment dar. In addition is not an inclusion of such low-reflection spaces in production lines workable, and also for Service companies can such high investments are not taken into account. A Mobile telematics diagnostics requires low-cost systems that operate at low cost Effort integrated into existing production and service environments can be.
Die vorliegende Erfindung geht aus von diesem Stand der Technik. Ihr liegt die Aufgabe zugrunde, ein kostengünstiges Diagnosesystem für Telematikeinrichtungen in Fahrzeugen zu entwickeln, das auch für den mobilen Einsatz geeignet ist. Diese Aufgabe wird bei einem Telematikdiagnosesystem gemäß Oberbegriff des Anspruchs 1 gelöst durch die kennzeichnenden Merkmale. Details und vorteilhafte Ausführungsbeispiele sind Gegenstand der jeweils zugeordneten Unteransprüche.The The present invention is based on this prior art. you the task is based, a cost-effective diagnostic system for telematics to develop in vehicles that are also suitable for mobile use is. This object is achieved in a telematics diagnostic system according to the preamble of claim 1 by the characteristic features. Details and advantageous embodiments are the subject of the respective associated subclaims.
Die Erfindung wird im Folgenden unter Bezugnahme auf die Figuren und den darin verwendeten Bezugszeichen näher beschrieben.The Invention is described below with reference to the figures and the reference numerals used therein described in more detail.

Entsprechend werden auch die nach Auswertung erhaltenen Diagnoseergebnisse gespeichert und stehen damit auch für spätere Auswertungen zur Verfügung. So kann für jedes getestete Fahrzeug ein individuelles Diagnose-Profil erstellt und abgespeichert werden, das auch bei einer späteren Wiederholung der Telematikdiagnose desselben Fahrzeugs zum Vergleich herangezogen werden kann. Damit können nicht nur Status-Informationen erfasst werden, sondern auch sich über einen Zeitraum allmählich entwickelnde Veränderungen.Corresponding The diagnostic results obtained after evaluation are also saved and are synonymous with that latter Evaluations available. So can for every tested vehicle creates an individual diagnosis profile and stored, even with a later repetition of the telematics diagnosis the same vehicle can be used for comparison. Can not do that only status information but also gradually developing over a period of time Changes.
