Bus-System in einem Kraftfahrzeug mit fahrzeugexternem Zugang Bus system in a motor vehicle with external access
Beschreibungdescription
Die Erfindung betrifft ein Bus-System in einem Kraftfahrzeug mit mindestens einem ersten Bus, der Steuergeräte als Busteilnehmer aufweist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a bus system in a motor vehicle with at least one first bus having control units as bus subscribers, according to the preamble of claim 1.
Bei der bekannten Diagnose der durch ein Bus-System vernetzten Steuergeräte gibt eine fahrzeugexterne Diagnose-Vorrichtung, insbesondere in einer Fahrzeug- Werkstatt, über eine Schnittstelle des Kraftfahrzeugs einen bestimmten Diagnose- Befehl auf das Bus-System und spricht hierdurch einen im angesprochenen Steuergerät gespeicherten Diagnose-Algorithmus an. Der Diagnose-Algorithmus prüft die Funktionsfähigkeit des betreffenden Steuergeräts und gibt eine entsprechende Nachricht auf das Bus-System, die von der Diagnose-Vorrichtung empfangen und ausgewertet wird. Ferner liest die Diagnose-Vorrichtung die Fehlerspeicher zu überprüfender Steuergeräte aus.In the known diagnosis of networked by a bus system control devices is a vehicle-external diagnostic device, in particular in a vehicle workshop, via an interface of the motor vehicle a specific diagnostic command on the bus system and thereby speaks a stored in the addressed control unit diagnosis Algorithm. The diagnostic algorithm checks the operability of the respective controller and gives a corresponding message to the bus system, which is received and evaluated by the diagnostic device. Furthermore, the diagnostic device reads out the error memories of control units to be checked.
Die bekannte Vorgehensweise bzw. das bekannte Bus-System ist wenig flexibel, weil die Diagnose-Algorithmen zum Selbsttest der Steuergeräte praktisch nicht veränderbar oder erweiterbar sind. Dies ist insbesondere bei einer Vielzahl vernetzter Steuergeräte, die aufeinander einwirken, von Nachteil.The known procedure or the known bus system is not very flexible, because the diagnostic algorithms for self-testing of the control devices are virtually unchangeable or expandable. This is particularly disadvantageous in the case of a large number of networked control devices which interact with one another.
Aufgabe der Erfindung ist die Bereitstellung eines im Hinblick auf die Fehlerdiagnose flexibleren Bus-Systems.The object of the invention is to provide a bus system that is more flexible with regard to fault diagnosis.
Diese Aufgabe wird durch ein Bus-System mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a bus system having the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.
Der Kern der Erfindung besteht darin, dass mindestens eine Gateway-Vorrichtung mit einer Zugangskontroll-Einrichtung als fahrzeugexterner Zugang mindestens zu dem ersten Bus und den an ihm angeschlossenen Steuergeräten vorgesehen ist. Die Gateway-Vorrichtung wird erfindungsgemäß in einen Diagnose-Modus gebracht, in dem, im Unterschied zu einem Betriebs-Modus der Gateway- Vorrichtung, der während des regulären Betriebs des Kraftfahrzeugs aktiviert ist, unter der Kontrolle der Gateway- Vorrichtung mindestens eine erste Bus-Nachricht mindestens einem ersten Steuergerät der Steuergeräte zugeführt wird. Die erste Busnachricht entspricht zumindest weitgehend einer Bus-Nachricht, die das erste Steuergerät auch während eines regulären Betriebs des Kraftfahrzeugs empfängt.The essence of the invention is that at least one gateway device is provided with an access control device as an external vehicle access at least to the first bus and the control units connected to it. The gateway device according to the invention is brought into a diagnostic mode in which, in contrast to an operating mode of the gateway device, which is activated during the regular operation of the motor vehicle, under the control of the gateway device at least a first bus Message is supplied to at least a first control device of the control units. The first bus message at least largely corresponds to a bus message which the first control unit also receives during regular operation of the motor vehicle.
Durch die erfindungsgemäße Lösung können ein oder mehrere reguläre Bus- Nachrichten, insbesondere von einer externen Diagnose-Vorrichtung, einem oder mehreren Steuergeräten zugeführt und damit deren Verhalten unter typischen Bus- Nachrichten-Bedingungen im Bus-System untersucht werden, insbesondere zur Ermittlung von fehlerhaften Steuergeräten oder Bus-Komponenten.By means of the solution according to the invention, one or more regular bus messages, in particular from an external diagnostic device, can be fed to one or more control devices and their behavior under typical bus message conditions in the bus system can be investigated, in particular for the determination of faulty control devices or bus components.
Bei einer Ausgestaltung der Erfindung ist vorgesehen, dass das erste Steuergerät eine erste Antwort-Nachricht im Anschluss an den Empfang der ersten Bus- Nachricht aussendet. Die erste Antwort-Nachricht entspricht zumindest weitgehend einer Bus-Nachricht, die das erste Steuergerät auch während des regulären Betriebs des Kraftfahrzeugs aussendet. Die erste Antwort-Nachricht wird über die Gateway-Vorrichtung einer fahrzeugexternen Diagnose-Vorrichtung zugeführt. Die fahrzeugexterne Diagnose-Vorrichtung übermittelt vorzugsweise der Gateway- Vorrichtung die erste Bus-Nachricht zur Weiterleitung an das erste Steuergerät.In one embodiment of the invention, it is provided that the first control unit emits a first response message following receipt of the first bus message. The first response message at least largely corresponds to a bus message which the first control unit also transmits during normal operation of the motor vehicle. The first response message is supplied via the gateway device to a vehicle-external diagnostic device. The vehicle-external diagnostic device preferably transmits to the gateway device the first bus message for forwarding to the first control device.
Bei einer Ausführungsform der Erfindung ist vorgesehen, dass die erste Bus- Nachricht eine Bus-Nachricht einer Mehrzahl von Bus-Nachrichten eines Bus- Nachrichten-Pakets ist und das Bus-Nachrichten-Paket eine Abfolge von Bus- Nachrichten darstellt, die dem ersten Steuergerät und/oder weiteren Steuergeräten zugeführt werden. Die hierdurch ausgelösten Antwort-Nachrichten des ersten und/oder der weiteren Steuergeräte werden von der Diagnose-Vorrichtung daraufhin überprüft, ob sie den Antwort-Nachrichten entsprechen, die während des regulären Betriebs des Kraftfahrzeugs bei ordnungsgemäßer Funktion des ersten Steuergeräts bzw. bei ordnungsgemäßer Funktion der angesprochenen Steuergeräte von dem ersten Steuergerät bzw. von den angesprochenen Steuergeräten ausgesandt werden. Anhand einer Abfolge von entsprechenden Bus-Nachrichten kann beispielsweise eine Abfolge von Schalter-Betätigungen simuliert und die Reaktion angesprochener Steuergeräte und Bus-Komponenten, insbesondere deren Antwort-Nachrichten, die über das Bus-System und die Gateway-Vorrichtung an die fahrzeugexterne Diagnose-Vorrichtung gelangen, mit den zu erwartenden Antwort-Nachrichten verglichen werden. Anhand solcher Szenarien bzw. Bus-Nachrichten-Pakete kann eine sehr realitätsnahe Analyse des erfindungsgemäßen Bus-Systems und seiner Komponenten durchgeführt werden. Zudem können solche Szenarien in sehr flexibler Weise an die Erfordernisse des betreffenden Fahrzeugs bzw. Bus-Systems angepasst und erforderlichenfalls im Laufe der Zeit modifiziert werden.In one embodiment of the invention, it is provided that the first bus message is a bus message of a plurality of bus messages of a bus message packet and the bus message packet represents a sequence of bus messages that the first control device and / or other control devices are supplied.

By means of a sequence of corresponding bus messages, it is possible to simulate, for example, a sequence of switch actuations and the response of addressed control devices and bus components, in particular their response messages, via the bus system and the gateway device to the vehicle-external diagnostic device can be compared with the expected response messages. On the basis of such scenarios or bus message packets, a very realistic analysis of the bus system according to the invention and its components can be carried out. In addition, such scenarios can be adapted in a very flexible manner to the requirements of the vehicle or bus system concerned and, if necessary, modified over time.
Eine Vielzahl solcher Analyse-Szenarien für verschiedene Fehlerbilder des Bus- Systems kann in der fahrzeugexternen Diagnose-Vorrichtung, insbesondere ein Laptop-Computer oder ein Personal Computer, bereitgehalten bzw. gespeichert werden. Zudem kann eine solche Bibliothek von Analyse-Szenarien auf der fahrzeugexternen Diagnose-Vorrichtung in technisch recht einfacher Weise durch eine Datenverbindung mit einer stets aktuellen entsprechenden Bibliothek, insbesondere beim Fahrzeughersteller, auf dem Laufenden gehalten werden. Ebenso kann von einem besonders spezialisierten Techniker in schwierigen Fällen über eine geeignete Datenverbindung mit der Gateway-Vorrichtung eine Fern- Analyse durch die Übertragung angepasster Analyse-Szenarien durchgeführt werden, was den Techniker in der Fahrzeug-Werkstatt entlastet.A plurality of such analysis scenarios for various fault images of the bus system can be stored or stored in the vehicle-external diagnostic device, in particular a laptop computer or a personal computer. In addition, such a library of analysis scenarios on the vehicle-external diagnostic device can be kept up to date in a technically quite simple manner by means of a data connection with an always current corresponding library, in particular at the vehicle manufacturer.
