In der Zeichnung wurde für funktionell entsprechende Komponen ten die gleichen Bezugszeichen wie in der bereits erläuterten Fig. 4 verwendet.In the drawing, the same reference numerals as in FIG. 4 already explained were used for functionally corresponding components.
Das in Fig. 1 dargestellte erste Ausführungsbeispiel umfaßt ein ein über die Diagnoseschnittstelle 3 mit den als Steuergeräte dargestellten elektrischen Einrichtungen 4 des Fahrzeugs 2 ver bindbares Prüfmodul 5. Die Ausgabeeinrichtung, mit welcher ei nem Bediener Prüfergebnisse oder Anweisungen über durchzufüh rende Betätigungen in Form eines Textes ausgebbar sind, wird gemäß der Erfindung durch eine dem Fahrzeug 2 zugehörige Ausga beeinrichtung 6 gebildet, nämlich einem zum Beispiel in der In strumententafel angeordneten Bildschirm, welcher bei bestim mungsgemäßem Gebrauch des Fahrzeugs 2 der Fahrerinformation dient, insbesondere durch Darstellung fahrzeugbezogener oder fahrroutenbezogener Daten. Die als Bildschirm ausgebildete Aus gabeeinrichtung 6 ist über die Diagnoseschnittstelle 3 von dem Prüfmodul ansteuerbar. Mit dieser Maßnahme entfällt ein exter ner mitzuführender Bildschirm.The first exemplary embodiment shown in FIG. 1 comprises a test module 5 that can be connected via the diagnostic interface 3 with the electrical devices 4 of the vehicle 2 shown as control devices. The output device with which an operator can output test results or instructions about operations to be carried out in the form of a text is formed according to the invention by an output device 6 belonging to the vehicle 2 , namely a screen arranged, for example, in the instrument panel, which at intended use of the vehicle 2 serves the driver information, in particular by displaying vehicle-related or route-related data. The display device 6 , designed as a screen, can be controlled by the test module via the diagnostic interface 3 . This measure eliminates the need for an external monitor to be carried.
Als Eingabeeinrichtung kann wie beim Stand der Technik in Fig. 4 ein Handsender verwendet werden. In einer vorteilhaften Wei terbildung wird die Eingabeeinrichtung jedoch durch eine dem Fahrzeug 2 zugehörige Eingabeeinrichtung 7 gebildet, beispiels weise einem Tastenfeld im Lenkrad des Fahrzeugs 2, wie in Fig. 1 dargestellt, welches bei bestimmungsgemäßem Gebrauch des Fahrzeugs als Eingabeeinrichtung für einen Bordrechner oder für ein Fahrzeugtelefon dient. Die Eingabeeinrichtung 7 steuert das Prüfmodul 5 auf dem Weg über die Diagnoseschnittstelle 3 an. Mit dieser Maßnahme kann eine separate Eingabeeinrichtung zur Ansteuerung des Prüfmoduls 5 durch den Bediener entfallen.As in the prior art in FIG. 4, a hand-held transmitter can be used as the input device. In an advantageous further development, however, the input device is formed by an input device 7 belonging to the vehicle 2 , for example a keypad in the steering wheel of the vehicle 2 , as shown in FIG. 1, which, when the vehicle is used as intended, as an input device for an on-board computer or for a Vehicle telephone is used. The input device 7 controls the test module 5 on the way via the diagnostic interface 3 . With this measure, a separate input device for activating the test module 5 by the operator can be dispensed with.
Alternativ oder ergänzend ist als Ausgabeeinrichtung eine im Fahrzeug ohnehin vorhandene Sprachausgabeeinrichtung nutzbar, welche bei bestimmungsgemäßem Gebrauch des Fahrzeugs der Fahre rinformation dient, insbesondere durch Ausgabe von Fahrinstruk tionen, die von einem Navigationssystem vorgegeben werden. Al ternativ oder ergänzend ist als Eingabeeinrichtung eine im Fahrzeug ohnehin vorhandene Sprachbefehlseingabeeinrichtung nutzbar, welche bei bestimmungsgemäßem Gebrauch des Fahrzeugs der sprachlichen Eingabe von Befehlen, wie z. B. zur Senderwahl beim Radio oder der Eingabe eines Zielortes bei einem Navigati onssystem dient.As an alternative or in addition, an im Vehicle speech device already available can be used, which if the vehicle is used as intended by the driver rinformation serves, in particular by issuing driving instructions tions that are specified by a navigation system. Al ternatively or additionally, an im is an input device Vehicle voice command input device already present usable if the vehicle is used as intended the voice input of commands, such as B. for channel selection on the radio or entering a destination with a Navigati system.
Zur Kommunikation mit dem Leitrechner 8 ist das Prüfmodul 5 mit einer Kommunikationseinrichtung 10 zum drahtlosen Datenaus tausch mit dem Leitrechner 8 oder dem Werksnetz 11, mit welchem der Leitrechner 8 verbunden ist, ausgestattet. Der Kontroll drucker 9 ist nicht unmittelbar an das Prüfmodul angeschlossen, sondern wird indirekt auf dem Wege über die Kommunikationsein richtung 10 und über das Werksnetz 11 von dem Prüfmodul 5 ange steuert. Dies ermöglicht, den Kontrolldrucker 9 räumlich vom Prüfmodul 5 zu trennen, so daß dieser nicht mit Fahrzeug 2 mit geführt werden braucht.For communication with the host computer 8 , the test module 5 is equipped with a communication device 10 for wireless data exchange with the host computer 8 or the works network 11 to which the host computer 8 is connected. The control printer 9 is not connected directly to the test module, but is controlled indirectly by the test module 5 via the communication device 10 and the works network 11 . This enables the control printer 9 to be physically separated from the test module 5 , so that it does not have to be carried with the vehicle 2 .
Mit den dargestellten erfindungsgemäßen Maßnahmen werden die zur bedienergeführten Prüfung benötigten Komponenten des Prüfsystems, welche mit einem auf einem Montageband bewegten Fahrzeug mitzuführen sind, auf das Prüfmodul 5 reduziert. Zur Durchführung der Prüfung genügt es daher, das Prüfmodul 5 mit tels des Diagnosesteckers über die Diagnoseschnittstelle 3 mit den elektrischen Einrichtungen 4 des Fahrzeugs 2 elektrisch zu verbinden und das Prüfmodul 5 an einem geeigneten Ort im, am oder auf dem Fahrzeug 2 abzustellen, so daß es nicht getrennt mitgeführt werden braucht. Damit können Einrichtungen zur Mit führung von Komponenten des Prüfsystems wie z. B. die Trage schiene 1 in Fig. 4 entfallen.With the measures according to the invention shown, the components of the test system required for operator-guided testing, which are to be carried with a vehicle moving on an assembly line, are reduced to the testing module 5 . To carry out the test, it is therefore sufficient to electrically connect the test module 5 by means of the diagnostic connector via the diagnostic interface 3 to the electrical devices 4 of the vehicle 2 and to switch off the test module 5 at a suitable location in, on or on the vehicle 2 , so that it does not need to be carried separately. This means that facilities for carrying components of the test system such. B. the stretcher rail 1 in Fig. 4 omitted.
In dem in Fig. 2 dargestellten zweiten Ausführungsbeispiel ist der der Erfindung zugrundeliegende Hauptgedanke - Nutzung von ohnehin im Fahrzeug vorhandenen elektrischen Einrichtungen als Komponenten eines Prüfsystems zur bedienergeführten Prüfung - fortgeführt. Die zur drahtlosen Kommunikation mit dem Leitrech ner 8 oder dem Werksnetz 11 benötigte Kommunikationseinrichtung wird von einer dem Fahrzeug zugehörigen Kommunikationseinrich tung 10 gebildet, die auf dem weg über die Diagnoseschnittstel le 3 mit dem Prüfmodul 5 kommunikativ verbunden ist und bei be stimmungsgemäßen Gebrauch des Fahrzeugs eine andere Funktion erfüllt. Mit dieser Maßnahme kann eine in dem Prüfmodul 5 inte grierte Kommunikationseinrichtung entfallen.In the second exemplary embodiment shown in FIG. 2, the main idea on which the invention is based - use of electrical devices which are present in the vehicle anyway as components of a test system for operator-controlled testing - is continued. The communication device required for wireless communication with the master computer 8 or the works network 11 is formed by a communication device 10 associated with the vehicle, which is communicatively connected to the test module 5 via the diagnostic interface 3 and, if the vehicle is used in accordance with intended use other function fulfilled. With this measure, an integrated communication device in the test module 5 can be omitted.
Geeignete dem Fahrzeug zugehörige Kommunikationseinrichtungen 10 können bereitgestellt werden von: uni- oder bidirektionale Infrarot- oder Funkfernbedienungsanlagen für Zentralschließan lagen, Wegfahrsperren, Fahrberechtigungssystemen, Diebstahl warnanlagen; desweiteren von auf Infrarot- oder Funkradarab standsmessungen basierenden Abstandswarngeräten, von auf Ultra schall basierenden Hilfseinrichtungen zum Einparken, von der Empfangseinrichtung eines Radios oder eines auf Funkwellen ba sierenden Globalen-Positionier-System (GPS) oder von einem Fahrzeugtelefon. Bei unidirektionalen Kommunikationseinrichtun gen mit denen Daten entweder nur empfangen oder gesendet werden können, ist der Datenaustausch systembedingt nur in eine Rich tung möglich, was für manche Prüfablauf keinen Nachteil bedeu tet.Suitable communication devices 10 associated with the vehicle can be provided by: unidirectional or bidirectional infrared or radio remote control systems for central locking systems, immobilizers, driver authorization systems, theft warning systems; furthermore from distance or distance warning devices based on infrared or radio radar measurements, from ultrasound-based auxiliary devices for parking, from the receiving device of a radio or a radio-based global positioning system (GPS) or from a vehicle telephone. With unidirectional communication devices with which data can either only be received or sent, data exchange is only possible in one direction due to the system, which is not a disadvantage for some test procedures.
In dem in Fig. 3 dargestellten dritten Ausführungsbeispiel ist der Gedanke der Nutzung von ohnehin im Fahrzeug vorhandenen elektrischen Einrichtungen nochmals weitergeführt, indem das Prüfmodul 5 durch ein dem Fahrzeug zugehöriges Steuergerät ge bildet wird, welches bei bestimmungsgemäßem Gebrauch des Fahr zeugs eine andere Funktion erfüllt. Durch diese Maßnahme kann das externe Prüfmodul und die Diagnoseschnittstelle entfallen.In the third exemplary embodiment shown in FIG. 3, the idea of using electrical devices already present in the vehicle is continued by the test module 5 being formed by a control unit belonging to the vehicle, which, when used as intended, fulfills another function. This measure means that the external test module and the diagnostic interface can be omitted.
Geeignet ist ein Steuergerät, welches zur Durchführung von Prüfaufgaben geeignet ist und beispielsweise bei bestimmungsge mäßem Gebrauch des Fahrzeugs Prüfaufgaben im Rahmen einer ON-BOARD-Diagnose übernimmt. Ein solches Steuergerät weist bereits den erforderlichen Vernetzungsgrad und notwendige Hardewarekom ponenten wie Mikropozessor mit Speicher und Softwarekomponenten z. B. Meßprogramme auf.A control device which is suitable for carrying out Test tasks is suitable and, for example, in the case of according to the use of the vehicle test tasks in the context of a ON-BOARD diagnosis takes over. Such a control device already has the required degree of networking and the necessary hardware components such as micro processor with memory and software components e.g. B. Measuring programs.
Alternativ ist auch denkbar, daß das integrierte Prüfmodul 5 nur mit einfacher Intelligenz ausgestattet ist und lediglich eine Kommunikationsschnittstelle zum Linienrechner 8 bildet, wobei der Prüfablauf durch den Linienrechner 8 gesteuert wird. Bei dieser Ausführung ist es vorteilhaft, wenn das Prüfmodul 5 durch das Steuergerät gebildet wird, an welches die Kommunika tionseinrichtung 10 angeschlossen ist.Alternatively, it is also conceivable that the integrated test module 5 is only equipped with simple intelligence and only forms a communication interface to the line computer 8 , the test sequence being controlled by the line computer 8 . In this embodiment, it is advantageous if the test module 5 is formed by the control device to which the communication device 10 is connected.
