Description

Die Erfindung betrifft ein Verfahren zum Betreiben eines elektronischen Wartungsbuchs für ein Fahrzeug.The invention relates to a method for operating an electronic maintenance book for a vehicle.

Die Erfindung betrifft weiterhin ein elektronisches Wartungsbuch für ein Fahrzeug zur Speicherung von durchgeführten Wartungsarbeiten.The invention further relates to an electronic maintenance book for a vehicle for storing performed maintenance.

Zur Dokumentation der an einem Fahrzeug durchgeführten notwendigen Wartungsarbeiten, zum Beispiel eines Ölwechsels oder eines Zahnriementauschs, werden üblicherweise gedruckte Wartungsbücher mit dem Fahrzeug mitgeführt, in die sämtliche durchgeführte Wartungsarbeiten manuell eingetragen werden. Diese Wartungsbücher beziehungsweise Servicehandbücher sind jedoch sehr fehlerträchtig und aufwändig zu pflegen. Darüber hinaus können sie verloren gehen oder durch eine Benutzung beziehungsweise Beschädigung unleserlich werden. Weiterhin ist eine direkte Zuordnung des Wartungsbuchs zu dem Fahrzeug beziehungsweise der Fahrgestellnummer des Fahrzeugs eigentlich nicht gegeben.To document the necessary maintenance work carried out on a vehicle, for example an oil change or a tooth exchange, printed maintenance books are usually carried along with the vehicle into which all the maintenance work carried out is entered manually. However, these maintenance books or service manuals are very error prone and expensive to maintain. In addition, they may be lost or illegible by use or damage. Furthermore, a direct assignment of the maintenance book to the vehicle or the chassis number of the vehicle is not actually given.

Eine fehlerfreie lückenlose Dokumentation der an einem Fahrzeug durchgeführten Wartungsarbeiten ist jedoch von Vorteil hinsichtlich des Werterhalts des Fahrzeugs. Auch wird die Lebensdauer des Fahrzeugs nicht aufgrund nicht durchgeführter Wartungsarbeiten unnötig verkürzt, da notwendige Wartungsarbeiten mit Hilfe des Wartungsbuchs ermittelt werden können.An error-free, complete documentation of the maintenance work carried out on a vehicle, however, is advantageous in terms of the value retention of the vehicle. Also, the life of the vehicle is not unnecessarily shortened due to not performed maintenance, since necessary maintenance can be determined using the maintenance book.

Die 198 12 318 A1 offenbart ein elektronisches, in einem Fahrzeug installiertes Wartungshandbuch.The 198 12 318 A1 discloses an electronic maintenance manual installed in a vehicle.

Der Erfindung liegt die Aufgabe zugrunde, ein Wartungsbuch für ein Fahrzeug bereitzustellen, das in sicherer Weise mit dem Fahrzeug verknüpft ist und gleichzeitig eine vereinfachte Pflege des Wartungsbuchs ermöglicht.The invention has for its object to provide a maintenance book for a vehicle that is securely linked to the vehicle and at the same time allows simplified maintenance of the maintenance book.

Diese Aufgabe wird mit den Merkmalen der unabhängigen Ansprüche gelöst.This object is achieved with the features of the independent claims.

Vorteilhafte Ausführungsformen ergeben sich aus den abhängigen Ansprüchen.Advantageous embodiments will be apparent from the dependent claims.

Die Erfindung baut auf dem gattungsgemäßen Verfahren dadurch auf, dass durchgeführte Wartungsarbeiten mit Fahrzeugdaten verknüpft und in einem in dem Fahrzeug angeordneten Speicher gespeichert werden. Das Verknüpfen der durchgeführten Wartungsarbeiten mit Fahrzeugdaten, zum Beispiel der Fahrgestellnummer und/oder dem aktuellen Kilometerstand des Fahrzeugs, ermöglicht eine präzise Zuordnung der durchgeführten Wartungsarbeiten zu einem bestimmten Fahrzeug. Dabei kann auch der Zeitpunkt, zu dem eine Wartungsarbeit durchgeführt worden ist, beispielsweise ein Ölwechsel, relevant sein und mitberücksichtigt werden. Weiterhin ist die Speicherung der so verknüpften Information in einem in dem Fahrzeug angeordneten Speicher geeignet, eine gegenüber einem gedruckten Wartungsbuch höhere Sicherheit vor einem Verlust des Wartungsbuchs zu gewährleisten.The invention is based on the generic method in that performed maintenance work associated with vehicle data and stored in a memory arranged in the vehicle. Linking the performed maintenance work with vehicle data, for example the chassis number and / or the current mileage of the vehicle, allows a precise assignment of the performed maintenance work to a specific vehicle. In this case, the time at which a maintenance work has been carried out, such as an oil change, be relevant and taken into account. Furthermore, the storage of the information thus linked in a memory arranged in the vehicle is suitable for ensuring a higher security against a loss of the maintenance book compared to a printed maintenance book.

Nützlicherweise kann vorgesehen, dass der in dem Speicher gespeicherte Informationsinhalt des elektronischen Wartungsbuchs in zumindest einem weiteren Speicher in dem Fahrzeug als eine Kopie gespeichert wird. Durch das Anlegen einer Kopie in zumindest einem weiteren Speicher in dem Fahrzeug wird eine Back-up-Lösung des elektronischen Wartungsbuchs geschaffen, falls der in dem Fahrzeug angeordnete Speicher durch einen Defekt ausfällt. Ein Mehraufwand durch das Anlegen der Kopie entsteht nur hinsichtlich eines weiteren Speicherbausteins und ist daher vernachlässigbar.Usefully, it may be provided that the information content of the electronic maintenance book stored in the memory is stored in at least one further memory in the vehicle as a copy. By creating a copy in at least one further memory in the vehicle, a back-up solution of the electronic maintenance book is created if the memory arranged in the vehicle fails due to a defect. An additional expenditure by the creation of the copy arises only with respect to a further memory module and is therefore negligible.

Dabei ist es nützlich, dass der in dem Speicher gespeicherte Informationsinhalt des elektronischen Wartungshandbuchs weiterhin in Teilen in mehreren anderen Speichern in dem Fahrzeug gespeichert wird, wobei die Teile zusammen eine Kopie des elektronischen Wartungsbuchs ergeben. Durch eine dezentrale Kopie des elektronischen Wartungsbuchs in mehreren anderen Speichern in dem Fahrzeug wird eine Manipulation des elektronischen Wartungsbuchs erschwert beziehungsweise ein unbeabsichtigtes Verändern des elektronischen Wartungsbuchs, beispielsweise durch Austauschen des Speichers, verhindert. Weiterhin können die anderen Speicher Informationsteile des elektronischen Wartungsbuchs umfassen, die mit der jeweiligen Baugruppe zusammenhängen, in denen sie angeordnet sind. Auf diese Weise können Teile des elektronischen Wartungsbuchs einfach zusammen mit den Baugruppen ausgetauscht werden. Dies kann beispielsweise bei einem Austauschmotor hilfreich sein, der eine andere Laufleistung aufweist, als ein ursprünglich in dem Fahrzeug angeordneter Fahrzeugmotor. Das elektronische Wartungsbuch kann dann durch den ersetzen anderen Speicher aktualisiert werden.In this case, it is useful that the information content of the electronic maintenance manual stored in the memory is further stored in parts in a plurality of other memories in the vehicle, the parts together resulting in a copy of the electronic maintenance book. By a decentralized copy of the electronic maintenance book in several other memories in the vehicle manipulation of the electronic maintenance book is difficult or inadvertent changing the electronic maintenance book, for example, by replacing the memory prevented. Furthermore, the other memory Information pieces of the electronic maintenance book, which are related to the respective assembly in which they are arranged. In this way, parts of the electronic maintenance book can be easily replaced together with the modules. This may be helpful, for example, in an exchange engine that has a different mileage than a vehicle engine originally arranged in the vehicle. The electronic maintenance book can then be updated by replacing other storage.

Weiterhin kann nützlich sein, dass einem Fahrzeugrechner des elektronischen Wartungsbuchs an dem Fahrzeug durchgeführte Wartungsarbeiten mitgeteilt werden und dass der Fahrzeugrechner das elektronische Wartungsbuch entsprechend aktualisiert. Ein in dem Fahrzeug angeordneter Fahrzeugrechner, der dem elektronischen Wartungsbuch zugehörig ist, kann in einfacher Weise das elektronische Wartungsbuch aktualisieren, wenn eine Wartungsarbeit an dem Fahrzeug durchgeführt wird und dieses dem Fahrzeugrechner mitgeteilt wird. Die Aktualisierung des elektronischen Wartungsbuchs umfasst dabei im Wesentlichen eine Erweiterung des elektronischen Wartungsbuchs, das heißt insbesondere werden ältere durchgeführte Wartungsarbeiten nicht gelöscht, falls eine weitere Wartungsarbeit an dem Fahrzeug durchgeführt wird.Furthermore, it may be useful for a vehicle computer of the electronic maintenance book to be notified of maintenance work carried out on the vehicle and for the vehicle computer to update the electronic maintenance book accordingly. A vehicle computer arranged in the vehicle, which is associated with the electronic maintenance book, can easily update the electronic maintenance book when a maintenance work is performed on the vehicle and this is communicated to the vehicle computer. The update of the electronic maintenance book essentially comprises an extension of the electronic maintenance book, that is, in particular, older performed maintenance work is not deleted if further maintenance work is performed on the vehicle.

Es kann vorgesehen sein, dass eine Kommunikation zwischen dem Fahrzeugrechner und einem anschließbaren fahrzeugextemen Servicerechner verschlüsselt wird. Über den anschließbaren fahrzeugextemen Servicerechner können dem Fahrzeugrechner durchgeführte Wartungsarbeiten mitgeteilt werden, die manuell eingegeben oder automatisch erfasst werden können. Weiterhin kann der Servicerechner den Inhalt des elektronischen Wartungsbuchs auslesen. Um Manipulationen vorzubeugen, ist es daher sinnvoll, die Kommunikation zwischen dem Fahrzeugrechner und dem fahrzeugextemen Servicerechner verschlüsselt durchzuführen.It can be provided that a communication between the vehicle computer and a connectable vehicle-extant service computer is encrypted. About the connectable fahrzeugxtemen service computer can be communicated to the vehicle computer maintenance, which can be entered manually or automatically recorded. Furthermore, the service computer can read the contents of the electronic maintenance book. In order to prevent manipulation, it is therefore advisable to encrypt the communication between the vehicle computer and the vehicle-specific service computer.

Vorteilhafterweise kann vorgesehen sein, dass Ersatzteile betreffende Informationen über den Servicerechner an das elektronische Wartungsbuch übertragen werden und dass die übertragenen Informationen mit Fahrzeugdaten verknüpft und in dem elektronischen Wartungsbuch gespeichert werden. Auch die bei Wartungsarbeiten verwendeten Ersatzteile können in dem elektronischen Wartungsbuch erfasst werden, wobei die Ersatzteile betreffenden Informationen beispielsweise den genauen Ersatzteiltyp, Herstellungsdatum, Hersteller und zulässige Standzeit umfassen können. In diesem Zusammenhang ist denkbar, dass die Ersatzteile selbst Identifikationsmittel aufweisen, zum Beispiel einen Transponder oder einen Barcode, der von einer Erfassungseinrichtung erfassbar ist, die an den fahrzeugextemen Servicerechner angeschlossen wird. Auf diese Weise kann die Erfassung der Ersatzteile und die Übertragung der Informationen in das elektronische Wartungsbuch nahezu automatisiert werden.Advantageously, it can be provided that information relating to spare parts is transmitted via the service computer to the electronic maintenance book and that the transmitted information is linked with vehicle data and stored in the electronic maintenance book. The spare parts used during maintenance work can also be recorded in the electronic maintenance book. For example, the information relating to replacement parts may include the exact type of replacement part, date of manufacture, manufacturer and allowable life. In this context, it is conceivable that the spare parts themselves have identification means, for example a transponder or a barcode, which can be detected by a detection device which is connected to the vehicle-specific service computer. In this way, the collection of spare parts and the transfer of information into the electronic maintenance book can be almost automated.

Nach dem Austausch einer Baugruppe mit einem anderen Speicher wird ein aktualisiertes elektronisches Wartungsbuch aus den nun neu in dem Fahrzeug vorhandenen anderen Speichern erstellt und in den Speicher übertragen. Auf diese Weise können Informationen über Ersatzteile einfach in das elektronische Wartungsbuch des Fahrzeugs eingepflegt werden.After replacing an assembly with another memory, an updated electronic maintenance book is created from the other memories now in the vehicle and transferred to memory. In this way, information about spare parts can easily be entered into the electronic maintenance book of the vehicle.

Das gattungsgemäße elektronische Wartungsbuch wird dadurch weiterentwickelt, dass das elektronische Wartungsbuch einen in dem Fahrzeug angeordneten Speicher umfasst, in dem der Informationsinhalt des elektronischen Wartungsbuchs gespeichert ist, wobei das elektronische Wartungsbuch geeignet ist, durchgeführte Wartungsarbeiten mit Fahrzeugdaten zu verknüpfen und in dem Speicher zu speichern. Auf diese Weise werden die Vorteile und Besonderheiten des erfindungsgemäßen Verfahrens auch im Rahmen einer Vorrichtung umgesetzt.The generic electronic maintenance book is further developed in that the electronic maintenance book includes a memory arranged in the vehicle, in which the information content of the electronic maintenance book is stored, the electronic maintenance book is suitable to combine performed maintenance with vehicle data and store in the memory. In this way, the advantages and special features of the method according to the invention are also implemented in the context of a device.

Dies gilt auch für die nachfolgend angegebenen besonders bevorzugten Ausführungsformen der erfindungsgemäßen Vorrichtung.This also applies to the following particularly preferred embodiments of the device according to the invention.

Diese wird nützlicherweise dadurch weitergebildet, dass das elektronische Wartungsbuch zumindest einen weiteren Speicher in dem Fahrzeug umfasst, in dem der Informationsinhalt des elektronischen Wartungsbuchs als Kopie gespeichert ist.This is usefully further developed in that the electronic maintenance book comprises at least one further memory in the vehicle, in which the information content of the electronic maintenance book is stored as a copy.

Es kann vorgesehen sein, dass das elektronische Wartungsbuch mehrere andere Speicher in dem Fahrzeug umfasst, in denen der Informationsinhalt des elektronischen Wartungshandbuchs in Teilen gespeichert ist, wobei die Teile zusammen eine Kopie des gesamten elektronischen Wartungshandbuchs ergeben.It may be contemplated that the electronic maintenance book includes a plurality of other memories in the vehicle in which the information content of the electronic service manual is stored in parts, the parts together providing a copy of the entire electronic maintenance manual.

Insbesondere kann vorgesehen sein, dass das elektronische Wartungsbuch einen Fahrzeugrechner umfasst, der mit einem fahrzeugextemen Servicerechner verbindbar ist.In particular, it can be provided that the electronic maintenance book comprises a vehicle computer which can be connected to a vehicle-external service computer.

Die Erfindung betrifft weiterhin ein Fahrzeug mit einem elektronischen Wartungsbuch in einer der beschriebenen Ausführungsformen.The invention further relates to a vehicle with an electronic maintenance book in one of the described embodiments.

Die Erfindung wird nun mit Bezug auf die begleitenden Zeichnungen anhand bevorzugter Ausführungsformen beispielhaft erläutert.The invention will now be described by way of example with reference to the accompanying drawings with reference to preferred embodiments.

Figur 1 zeigt eine schematische Darstellung der Systemarchitektur eines erfindungsgemäßen elektronischen Wartungsbuchs. Ein dargestelltes Fahrzeug 12 mit einem elektronischen Wartungsbuch 10 und einem Subsystemrechner 30 umfasst weiterhin eine Schnittstelle 34, über die ein Servicerechner 24 mit einem Fahrzeugrechner 14 des elektronischen Wartungsbuchs 10 koppelbar ist. Der Fahrzeugrechner 14 umfasst Speicher 16 und das elektronische Wartungsbuch 10 umfasst weiterhin weiteren Speicher 18 und anderen Speicher 20, 22. Der fahrzeugexteme Servicerechner 24 ist mit einer Erfassungseinrichtung 32 koppelbar, die geeignet ist, Identifikationsmittel zu erfassen, die an Ersatzteilen 26, 28 angeordnet sind. Weiterhin kann an dem fahrzeugextemen Servicerechner 24 eine manuelle Ersatzteilnummerneingabe 36 und/oder eine manuelle Wartungscodeeingabe 38 erfolgen. Die von der Erfassungseinrichtung 32 beziehungsweise durch die manuellen Eingaben 36, 38 ermittelten Informationen können von dem fahrzeugextemen Servicerechner 24 über die Schnittstelle 34 in verschlüsselter Form an den Fahrzeugrechner 14 des elektronischen Wartungsbuch übertragen werden. Der Fahrzeugrechner 14 koppelt die übertragenen Informationen an Fahrzeugdaten, beispielsweise an einen aktuellen Kilometerstand des Fahrzeugs, das aktuelle Datum und/oder die Fahrzeugfahrgestellnummer, wobei der Fahrzeugrechner 14 diese Informationen beispielsweise von dem Subsystemrechner 30 erhalten kann. Der Subsystemrechner 30 kann ein Instrumentierungsrechner oder ein EAC-/EBS-Steuergerät sein. Neben den bereits genannten Fahrzeugdaten können auch Fehlerinformationen und die aktuelle GPS-Position bei der Erstellung des elektronischen Wartungsbuchs verwendet werden. Nach der Verknüpfung aller erhaltenen Informationen speichert der Fahrzeugrechner 14 den erzeugten Datensatz in dem Speicher 16 ab, wobei insbesondere ältere Wartungsarbeiten, die an dem Fahrzeug 12 durchgeführt worden sind und als Datensatz ebenfalls in dem Speicher 16 gespeichert wurden, nicht überschrieben werden. Zusätzlich überträgt und speichert der Fahrzeugrechner 14 den erzeugten Datensatz an den weiteren Speicher 18 und je nach Art der durchgeführten Wartungsarbeiten an verschiedene andere Speicher 20, 22, wobei in den anderen Speichern 20, 22 verschiedene Teile des Informationsinhaltes des elektronischen Wartungsbuchs gespeichert werden. FIG. 1 shows a schematic representation of the system architecture of an electronic maintenance book according to the invention. An illustrated vehicle 12 with an electronic maintenance book 10 and a subsystem computer 30 further comprises an interface 34, via which a service computer 24 can be coupled to a vehicle computer 14 of the electronic maintenance book 10. The vehicle computer 14 includes memory 16 and the electronic maintenance book 10 further comprises further memory 18 and other memory 20, 22. The vehicle-equipped service computer 24 is coupled to a detection device 32, which is adapted to detect identification means, which are arranged on spare parts 26, 28 , Furthermore, a manual replacement part number input 36 and / or a manual maintenance code input 38 can be made to the vehicle-specific service computer 24. The information determined by the detection device 32 or by the manual inputs 36, 38 can be transmitted from the vehicle-specific service computer 24 via the interface 34 in encrypted form to the vehicle computer 14 of the electronic maintenance book. The vehicle computer 14 couples the transmitted Information on vehicle data, for example on a current mileage of the vehicle, the current date and / or the vehicle chassis number, wherein the vehicle computer 14 may receive this information, for example, from the subsystem computer 30. The subsystem computer 30 may be an instrumentation computer or an EAC / EBS controller. In addition to the vehicle data already mentioned, error information and the current GPS position can also be used when creating the electronic maintenance book. After linking all the information obtained, the vehicle computer 14 stores the generated data record in the memory 16, in particular older maintenance work that has been carried out on the vehicle 12 and was also stored as a data record in the memory 16, not be overwritten. In addition, the vehicle computer 14 transfers and stores the generated data record to the further memory 18 and, depending on the type of maintenance performed, to various other memories 20, 22, wherein different parts of the information content of the electronic maintenance book are stored in the other memories 20, 22.

Der fahrzeugexteme Servicerechner 24 kann über die Schnittstelle 34 den Inhalt des Speichers 16 durch den Fahrzeugrechner 14 auslesen, um beispielsweise notwendige anstehende Wartungsarbeiten ermitteln zu können. Sollte der Fahrzeugrechner 14 mit dem Speicher 16 defekt sein, beziehungsweise der Speicher 18 defekt sein, so kann die jeweils beschädigte Komponente ausgetauscht werden und das elektronische Wartungsbuch 10 durch die in der jeweils anderen Komponente gespeicherte Information wieder vollständig hergestellt werden. Falls eine Baugruppe mit einem anderen Speicher 20; 22 vollständig ausgetauscht werden muss, so kann ein aktualisiertes Wartungsbuch durch Zusammensetzen der in den nun vorhandenen neuen anderen Speichern 20, 22 gespeicherten Teile des elektronischen Wartungsbuchs erstellt werden. Dies kann beispielsweise notwendig sein, wenn ein Austauschmotor in das Fahrzeug 12 eingebaut wird, der eine von dem ursprünglichen Motor unterschiedliche Wartungsgeschichte und Laufleistung aufweist. Der Austauschmotor umfasst einen eigenen anderen Speicher 20; 22, wobei alle anderen Speicher 20, 22 zusammen ein aktualisiertes elektronisches Wartungsbuch 10 ergeben.The vehicle-specific service computer 24 can read out the contents of the memory 16 by the vehicle computer 14 via the interface 34, in order to be able to determine, for example, necessary pending maintenance work. If the vehicle computer 14 is defective with the memory 16 or the memory 18 is defective, then the respectively damaged component can be exchanged and the electronic maintenance book 10 can be completely restored by the information stored in the respective other component. If an assembly with another memory 20; 22 has to be completely replaced, an updated maintenance book can be created by assembling the parts of the electronic maintenance book which are stored in the now new, other memories 20, 22. This may be necessary, for example, if an exchange engine is installed in the vehicle 12 that has a different maintenance history and mileage from the original engine. The replacement engine includes its own other memory 20; 22, with all other memories 20, 22 together resulting in an updated electronic maintenance book 10.

Figur 2 zeigt ein Flussdiagramm zur Veranschaulichung der Arbeitsweise eines erfindungsgemäßen elektronischen Wartungsbuchs. Gestartet wird bei Schritt 100, in welchem festgestellt wird, dass das Fahrzeug einer Wartungsarbeit bedarf. Zunächst wird dann bei Schritt 102 ein fahrzeugextemer Servicerechner angeschlossen und die durchzuführende Wartungsarbeit in Schritt 104 erfasst. Sind Ersatzteile bei dieser Wartungsarbeit notwendig, 106-ja, so werden bei Schritt 108 die Informationen des notwendigen Ersatzteils erfasst. Anschließend wird bei Schritt 110 das elektronische Wartungsbuch aktualisiert. Waren keine Ersatzteile notwendig, 106-nein, so wird ebenfalls bei Schritt 110 fortgefahren und das elektronische Wartungsbuch aktualisiert. Nach der Aktualisierung des elektronischen Wartungsbuches kann der normale Fahrbetrieb des Fahrzeugs bei Schritt 112 wieder aufgenommen werden. Schritt 100, dass die Wartung erforderlich ist, kann übersprungen werden, da eine Wartungsarbeit natürlich durchgeführt werden kann, bevor sie notwendig ist. FIG. 2 shows a flowchart for illustrating the operation of an electronic maintenance book according to the invention. The process begins at step 100, where it is determined that the vehicle requires maintenance. First, a vehicle-specific service computer is then connected at step 102 and the maintenance work to be performed is detected in step 104. If spare parts are necessary in this maintenance work, yes, the information of the necessary spare part is recorded in step. Subsequently, at step 110, the electronic maintenance book is updated. If no replacement parts were required, 106-no, then the process continues at step 110 and the electronic maintenance book is updated. After updating the electronic maintenance book, the normal driving operation of the vehicle may be resumed at step 112. Step 100, that maintenance is required, can be skipped, as a maintenance job can of course be done before it is necessary.

Die in der vorstehenden Beschreibung, in den Zeichnungen sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung wesentlich sein.The features of the invention disclosed in the foregoing description, in the drawings and in the claims may be essential to the realization of the invention both individually and in any combination.
