Verfahren und Vorrichtung zum Versorgen von Kraftfahrzeugen mit Daten oder zum DatenaustauschMethod and device for supplying data to motor vehicles or for data exchange
Die Erfindung bezieht sich auf ein Verfahren zum Versorgen von Kraftfahrzeugen mit Daten, die zum Betrieb, zur Überwachung und/oder Wartung von Kraftfahrzeugen, insbesondere von geregelten Bremsanlagen und anderen KFZ- Regelungs- oder Steuerungssystemen, dienen, zum Austausch von Daten und/oder zum Abfragen, ändern, Aktualisieren von Daten dieser Art. Eine Anordnung zur Durchführung des Verfahrens gehört ebenfalls zur Erfindung.The invention relates to a method for supplying motor vehicles with data which are used for the operation, monitoring and / or maintenance of motor vehicles, in particular regulated brake systems and other motor vehicle regulation or control systems, for the exchange of data and / or Querying, changing, updating data of this type. An arrangement for carrying out the method is also part of the invention.
Zur Erhöhung der Sicherheit und des Fahrkomforts von Kraftfahrzeugen werden in zunehmendem Maße elektronische Regelungs- und Steuerungssysteme, Überwachungs- und Warnsysteme usw. in die einzelnen Fahrzeuge installiert. Die Funktion solcher Systeme beruht vornehmlich auf Datenverarbeitung, weshalb dem Laden der Daten, der Datenaktualisierung, dem Datenaustausch, der Überwachung der einzelnen Vorgänge große Bedeutung zukommt.To increase the safety and driving comfort of motor vehicles, electronic regulation and control systems, monitoring and warning systems, etc. are increasingly being installed in the individual vehicles. The function of such systems is primarily based on data processing, which is why loading data, updating data, exchanging data and monitoring individual processes is of great importance.
Das Laden der Regelungsprogramme gehört zur Fertigung des Fahrzeugs. Das Überwachen solcher Daten, das Aktualisieren der Programme, das Auslesen von Verschleißdaten etc. geschieht im Rahmen von Reparaturen oder Wartungsarbeiten in den Werkstätten, die hierzu mit entsprechenden Diagnosegeräten, Datenhbertragungseinrichtungen und Computern ausgerüstet sind. Der Austausch der Daten und deren Auswertung ist den Fachleuten in den Werkstätten vorbehalten .The loading of the control programs is part of the production of the vehicle. The monitoring of such data, the updating of the programs, the reading of wear data etc. are carried out as part of repairs or maintenance work in the workshops, which are equipped with the appropriate diagnostic devices, data transmission devices and computers. The exchange of data and their evaluation is reserved for specialists in the workshops.
Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren zu entwickeln, das ein von den Service-Intervallen undThe invention is based on the object to develop a method that one of the service intervals and
BESTAT I GUNGSKOP I E Werkstattbesuchen unabhängiges "Kommunizieren" mit der Elektronik des Fahrzeugs, nämlich ein von den Werkstattbesuchen unabhängiges Erfassen, Auswerten, Austauschen und Aktualisieren der verschiedenen Daten und Programme zuläßt. Natürlich sollte dieses (zusätzliche und häufigere) Kommunizieren zwischen der installierten Elektronik und den externen Überwachungs- oder Serviceeinrichtungen mit höchstens geringfügig höherem Kosten- und Zeitaufwand für den Fahrzeughalter verbunden sein.BESTAT I GUNGSKOP IE Workshop visits independent "communication" with the electronics of the vehicle, namely a recording, evaluation, exchange and updating of the various data and programs independent of the workshop visits. Of course, this (additional and more frequent) communication between the installed electronics and the external monitoring or service facilities should involve at most only slightly higher costs and time for the vehicle owner.
Es hat sich nun herausgestellt, daß diese Aufgabe mit einem Verfahren der eingangs genannten Art gelöst werden kann, dessen Besonderheit darin besteht, daß während des Betankens des Fahrzeugs die Datenübertragung mit Hilfe von in dem Betankungsweg installierten Datenübertragungseinrichtungen durchgeführt wird.It has now been found that this object can be achieved with a method of the type mentioned at the beginning, the special feature of which is that during the refueling of the vehicle, the data transmission is carried out with the aid of data transmission devices installed in the refueling path.
Unabhängig von den Service-Intervallen und ohne zusätzlichen Zeitaufwand wird erfindungsgemäß bei jedem Tanken eine Datenübertragung durchgeführt, die in unterschiedlicher Weise und zu verschiedenartigem Nutzen ausgewertet werden kann. Dies geschieht quasi unbemerkt von dem Fahrer und ohne Zeitaufwand. Gleichzeitig mit dem Tanken, d.h. mit dem Zuführen von Treibstoff, findet eine Kommunikation zwischen den elektronischen Systemen des Fahrzeugs und den externen Überwachungseinrichtungen statt. Das Fahrzeug wird bei dem Tankvorgang automatisch über die Tankanlage und, je nach Realisierung der Erfindung, über eine Online-Verbindung mit Servicestellen oder mit dem Werk (dem Fahrzeughersteller) verbunden wird.Regardless of the service intervals and without additional expenditure of time, according to the invention a data transmission is carried out with each refueling, which can be evaluated in different ways and for different uses. This happens practically unnoticed by the driver and without expenditure of time. Simultaneously with refueling, i.e. with the supply of fuel, communication takes place between the electronic systems of the vehicle and the external monitoring devices. During the refueling process, the vehicle is automatically connected via the tank system and, depending on the implementation of the invention, via an online connection to service points or to the factory (the vehicle manufacturer).
Das erfindungsgemäße Verfahren ist natürlich nicht auf das Tanken von Treibstoffen beschränkt. Ausschlaggebend ist das regelmäßig erforderliche Anfahren einer bestimmten Stelle, an der sich eine Verbindung zum Fahrzeug herstellen läßt, die auch zur Datenübertragung genutzt werden kann. BeimThe method according to the invention is of course not limited to the refueling of fuels. It is crucial Regularly required starting at a certain point at which a connection to the vehicle can be established, which can also be used for data transmission. At the
"Tanken'Von elektrischer Energie sind diese Voraussetzungen ebenfalls erfüllt. Beim Laden der Fahrzeugbatterie lassen sich neue Programme und Daten zum Aktualisieren oder Abfragen von Informationen dem Ladestrom aufmodulieren ."Refueling 'of electrical energy also fulfills these requirements. When the vehicle battery is being charged, new programs and data for updating or querying information can be modulated onto the charging current.
Die Datenübertragung geschieht grundsätzlich in beiden Richtungen. Auf diese Weise können z.B. Parametersätze oder komplette Software-Programme in die Fahrzeugelektronik geladen werden, wenn die einzelnen Steuergeräte über entsprechende Datenspeicher und Einrichtungen verfügen.The data transfer basically takes place in both directions. In this way e.g. Parameter sets or complete software programs can be loaded into the vehicle electronics if the individual control units have the appropriate data storage and facilities.
Nach einem vorteilhaften Ausführungsbeispiel der Erfindung werden während des Betankens des Fahrzeugs Daten übertragen, abgefragt oder ausgetauscht, die eine oder mehrere der folgenden Informationen enthalten:According to an advantageous embodiment of the invention, data are transmitted, queried or exchanged during the refueling of the vehicle which contain one or more of the following information:
- technische Diagnose oder Analyse des Bremsensystems, des Fahrwerks, des elektrischen Systems, eines oder mehrerer Fahrzeug-Regelungssysteme, des Antriebsmotors, insbesondere Informationen über- Technical diagnosis or analysis of the brake system, the chassis, the electrical system, one or more vehicle control systems, the drive motor, in particular information about
- den Luftdruck der einzelnen Räder,- the air pressure of the individual wheels,
- den Ölstand im Antriebsmotor,- the oil level in the drive motor,
- die Bremsbelagstärke etc..- the brake pad thickness etc.
Auf diese Weise wird das Fahrzeug überwacht.The vehicle is monitored in this way.
Das erfindungsgemäße Verfahren macht es auch möglich, die Art des getankten Treibstoffs, die Benzinqualität (z.B. Oktan-Zahl, Bleigehalt etc.) und andere Daten dem Motormanagement zuzuleiten und dadurch automatisch die Motorsteuerung den Gegebenheiten anzupassen.The method according to the invention also makes it possible to forward the type of fuel refueled, the gasoline quality (eg octane number, lead content, etc.) and other data to the engine management and thereby automatically the Adapt motor control to the circumstances.
Wird eine Abweichung vom vorgegebenen Reifen-Solldruck bei der Datenübermittlung während des Tankens festgestellt, wird dies dem Fahrzeugführer optisch oder akustisch signalisiert. Er wird zur Korrektur des Reifendrucks aufgefordert.If a deviation from the specified target tire pressure is found during data transmission during refueling, this is signaled to the driver of the vehicle optically or acoustically. He is asked to correct the tire pressure.
Die erfindungsgemäße Anordnung zur Durchführung des Verfahrens ist als Bestandteil einer üblichen Tankstelle ausgebildet und mit einer Datenübertragungseinrichtung ausgerüstet, die eine im Kraftfahrzeug und in der Betankungseinrichtung, vorzugsweise an dem Einfüllstutzen des Tanks und an der Zapfpistole, installierte Schnittstelle umfaßt, über die beim Tankvorgang der Datenfluß oder Datenaustausch stattfindet.The arrangement according to the invention for carrying out the method is designed as part of a conventional petrol station and is equipped with a data transmission device which comprises an interface installed in the motor vehicle and in the refueling device, preferably on the filler neck of the tank and on the fuel nozzle, via which the data flow during the refueling process or data exchange takes place.
Als Datenübertragungseinrichtung eignet sich z.B. eine in oder an der Zapfpistole und an dem Kraftfahrzeug installierte Sende- und Empfangseinrichtung, die in beiden Richtungen Daten übertragen kann. Solche Übertrager basieren zweckmäßigerweise auf einer elektromagnetischen, induktiven, kapazitiven oder optischen (Infrarotsensoren und -empfänger etc.) Übertragungsmethode. Vorzuziehen sind Sender/Empfänger- oder Geber/Aufnehmer-Systeme, bei denen die Informationsübertragung berührungslos erfolgt.A suitable data transmission device is e.g. a transmitting and receiving device installed in or on the fuel nozzle and on the motor vehicle, which can transmit data in both directions. Such transmitters are expediently based on an electromagnetic, inductive, capacitive or optical (infrared sensors and receivers, etc.) transmission method. Transmitter / receiver or transmitter / transducer systems in which information is transmitted without contact are preferred.

Nach der Fahrzeug-Identifikation im Programmschritt 21, nach dem Suchen der Fahrzeugkartei 22, nach dem Empfang der Fehlerbotschaft in 23 und/oder der Verschleißbotschaft in 24, nach dem Bestätigen und Quittieren der Ergebnisse (25,26) werden die benötigten Kalibrierdaten im Schritt 27, symbolisiert durch den Zuordnungspfeil P5 zum Fahrzeug 1 gesendet und veranlassen dort die erwünschten Einstellungen oder Parameteranpassungen (im Schritt 20).The processes shown in FIG. 3 in the program part extending from the nozzle 4 to the computer 5 are coordinated with the sequence described with reference to FIG. 2. After the vehicle identification in program step 21, after searching the vehicle file 22, after receiving the error message in 23 and / or the wear message in 24, after confirming and acknowledging the results (25, 26), the required calibration data in step 27 , symbolized by the assignment arrow P5 sent to the vehicle 1 and initiate the desired settings or parameter adjustments there (in step 20).
Schließlich ist in Fig. 3 noch der weitere Signalfluß zu einer Datenauswertung 28 und einer Verzweigung 29 dargestellt, die entweder das Stillsetzen des Fahrzeugs (Schritt 30) und/oder die Anfertigung des Fehlerprotokolls bewirkt . Der Signalfluß über die Pfeile Pl bis P4 ergibt sich aus den angegebenen Aufgaben der einzelnen Aktionen oder Schritte, die durch die Pfeile miteinander verbunden sind.Finally, FIG. 3 shows the further signal flow to a data evaluation 28 and a branch 29, which either brings the vehicle to a standstill (step 30) and / or produces the error log. The signal flow via the arrows P1 to P4 results from the specified tasks of the individual actions or steps which are connected by the arrows.
Es versteht sich von selbst, daß die dargestellte Prozedur nur eine von zahlreichen Verknüpfungen, Möglichkeiten zur Auswertung oder Signallaufplanen wiedergibt. Wichtig ist, daß aus den übertragenen und ausgewerteten Informationen die geeigneten Maßnahmen zur Fehlererkennung, Fehlersignalisierung und, wenn möglich, Fehlerbehebung abgeleitet werden. It goes without saying that the procedure shown represents only one of numerous links, possibilities for evaluation or signal scheduling. It is important that the appropriate measures for error detection, error signaling and, if possible, troubleshooting are derived from the transmitted and evaluated information.
