Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Manipulationssicherung eines Kilometerzählers oder eines Fahrzeugschreibers eines Kraftfahrzeugs.The present invention relates to a method and a device for tamper-proofing of an odometer or a vehicle recorder of a motor vehicle.

Bei heutigen Fahrzeugsteuerkonzepten ist es möglich, mittels CAN-Schnittstellen eine Verbindung zwischen einem Fahrzeugcockpit und einem Motorsteuergerät herzustellen. Es ist bekannt, den Kilometerstand eines im Cockpit vorgesehenen Wegstrecken- bzw. Kilometerzählers im Fehlerfall in das Motorsteuergerät einzulesen und zu speichern. Mit dieser Maßnahme kann gegebenenfalls eine Fehlerdiagnose erleichtert werden.In today's vehicle control concepts, it is possible to establish a connection between a vehicle cockpit and an engine control unit by means of CAN interfaces. It is known to read the mileage of a provided in the cockpit distance or odometer in case of failure in the engine control unit and store. If necessary, a fault diagnosis can be facilitated with this measure.

Aus der DE OS 29 11 1160 ist eine Vorrichtung zum Verhindern einer unbefugten Inbetriebsetzung von Fahrzeugen mit einem vorzugsweise mit dem für die mechanischen Schlösser des Fahrzeugs vorgesehenen Schlüssel verbundenen Informationsträger und mit einer Auswerteschaltung, welche ein Signal auslöst, wenn die richtige Information eingeben wurde, bekannt. Es ist dort insbesondere beschrieben, daß der Stand eines Kilometerzählers und/oder eines Betriebsstundenzählers auf den Fahrzeugschlüssel übertragbar und dort speicherbar ist. Das Fahrzeug kann nur dann neu gestartet werden, wenn beim Startvorgang der Start des Kilometerzählers bzw. des Betriebsstundenzählers von dem Schlüssel zurück in eine fahrzeugseitige Auswerteeinheit übertragen wird. Diese Druckschrift beschäftigt sich mit einer Diebstahlsicherung von Fahrzeugen, nicht jedoch mit der in jüngster Zeit immer häufiger auftretenden Manipulation von Kilometerzählern bzw. von Fahrtenschreibern.From the DE OS 29 11 1160 is a device for preventing unauthorized operation of vehicles with a preferably associated with the provided for the mechanical locks of the vehicle key Information carrier and with an evaluation circuit which triggers a signal when the correct information was entered, known. It is described there in particular that the state of an odometer and / or an operating hours counter can be transferred to the vehicle key and stored there. The vehicle can only be restarted if, during the starting process, the start of the odometer or the operating hours counter is transmitted from the key back to a vehicle-side evaluation unit. This document is concerned with an anti-theft device of vehicles, but not with the recent occurrence of more frequent manipulation of odometers or tachographs.

Ein weiteres Dokument des Stands der Technik ist GB 2326720 A . Es beschreibt ein Verfahren zur Manipulationssicherung von Wegstreckenzählern, bei dem in regelmäßigen Abständen der Wegstreckenzählerstand ausgelesen und in mehreren nichtflüchtigen, fahrzeuginternen Speichern abgespeichert wird. Diese abgespeicherten Werte werden regelmäßig synchronisiert, wobei der größte gespeicherte Wert kleinere Werte überschreibt. In diese Synchronisation wird der vom Wegstreckenzähler aktuell dargestellte Wert mit einbezogen.Another prior art document is GB 2326720 A , It describes a method for tamper-proofing of odometer, in which the odometer reading is read at regular intervals and stored in several non-volatile, in-vehicle memories. These stored values are periodically synchronized, with the largest stored value overwriting smaller values. In this synchronization, the value currently displayed by the odometer is included.

Aufgabe der Erfindung ist eine einfache und preiswerte Bereitstellung einer Manipulationssicherung von Wegstreckenzählern oder Fahrtenschreibern von Kraftfahrzeugen.The object of the invention is a simple and inexpensive provision of a tamper-proofing of odometer or tachographs of motor vehicles.

Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 sowie eine Vorrichtung mit den Merkmalen des Patentanspruchs 4.This object is achieved by a method having the features of patent claim 1 and a device having the features of patent claim 4.

Erfindungsgemäß ist nun eine in einfacher und preiswerter Weise bereitzustellende Manipulationssicherung von Wegstreckenzählern oder Fahrtenschreibern von Kraftfahrzeugen zur Verfügung gestellt. Zur wirksamen Durchführung einer Manipulation müßten sowohl im Cockpit (d. h. dem Wegstreckenzähler) und im Steuergerät Änderungen der aktuellen bzw. gespeicherten Wegstreckenstände vorgenommen werden, was einen gegenüber herkömmlichen Manipulationsmöglichkeiten wesentlich höheren und technisch schwierigeren Aufwand darstellt.In accordance with the invention, a manipulation safeguard of odometer or tachographs of motor vehicles to be provided in a simple and economical manner is now provided. To effectively carry out a manipulation both in the cockpit (ie the odometer) and in the control unit changes to the current or stored distance distances should be made, which compared to conventional Manipulation opportunities represents much higher and technically difficult effort.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche.Advantageous embodiments of the method according to the invention are the subject of the dependent claims.

Gemäß des erfindungsgemäßen Verfahrens wird bei einer Nichtübereinstimmung der jeweiligen aktuellen und gespeicherten Wegstreckenstände bzw. -werte eine Motorfunktion des Kraftfahrzeugs unterbunden. Durch diese Maßnahme ist als zusätzlicher Effekt eine wirksame Abschreckung bzw. Sicherung vor einem Diebstahl des Kraftfahrzeuges zur Verfügung gestellt.According to the method according to the invention, if the respective current and stored distance values or values do not match, an engine function of the motor vehicle is prevented. By this measure, an effective deterrence or protection against theft of the motor vehicle is provided as an additional effect.

Zweckmäßigerweise wird bei Nichtübereinstimmung der jeweiligen Wegstreckenstände ein Alarmsignal ausgegeben. Ein derartiges Alarmsignal kann entweder unmittelbar akustisch oder optisch, oder über entsprechende Funkverbindungsmittel an eine Sicherungszentrale übermittelt werden. Im Zusammenspiel mit entsprechenden, an sich bekannten Ortungsmitteln ist ein Kraftfahrzeug, welches einer Manipulation des Wegstreckenzählers unterzogen wird, in einfacher Weise auffindbar.Conveniently, an alarm signal is output in case of disagreement of the respective distances. Such an alarm signal can be transmitted either directly acoustically or visually, or via appropriate radio communication means to a backup center. In conjunction with corresponding, known per se locating a motor vehicle, which is subjected to a manipulation of the odometer, can be found in a simple manner.

Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung sind die Mittel zur Feststellung des aktuellen Wegstreckenzählerstandes und/oder zum Vergleich des Wegstreckenzählerstandes bei Motorneustart mit einem gespeicherten Wegstreckenzählerstand in Form eines Kombiinstrumentes, und erfindungsgemäß die Mittel zur Veranlassung geeigneter Maßnahmen für den Fall, daß der beim Motorneustart festgestellte Wegstreckenzählerstand und der gespeicherte Wegstreckenzählerstand nicht übereinstimmen, in Form eines Getriebe- oder Motorsteuergerätes realisiert. Derartige, herkömmlicherweise bei Kraftfahrzeugen vorgesehene Einrichtungen sind ohne bzw. mit nur geringem Aufwand im Sinne der angegebenen Funktionalitäten modifizierbar.According to a preferred embodiment of the device according to the invention, the means for determining the current odometer reading and / or comparing the odometer reading at engine restart with a stored odometer reading in the form of a combination instrument, and according to the invention the means for initiating appropriate measures for the In the event that the odometer reading found during the engine restart and the stored odometer reading do not match, realized in the form of a transmission or engine control unit. Such, conventionally provided in motor vehicles facilities can be modified without or with little effort in terms of the specified functionality.

Eine bevorzugte Ausführungsform der Erfindung wird nun anhand der beigefügten Zeichnung im einzelnen beschrieben. In dieser zeigt

Figur 2
schematisch eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung.
A preferred embodiment of the invention will now be described in detail with reference to the accompanying drawings. In this shows
FIG. 1
a flowchart for explaining a preferred embodiment of the method according to the invention, and
FIG. 2
schematically a preferred embodiment of the device according to the invention.

In einem Schritt 100 erfolgt bei einem Abstellen des Motors des Kraftfahrzeuges eine Speicherung des Wegstrecken- bzw. Km-Standes des Wegstreckenzählers. Die Speicherung des Kilometer-Standes erfolgt in einem Speicher eines fahrzeuginternen Steuergeräts, welches Einfluß auf die Fahrzeugbewegung hat. Als Beispiel sei insbesondere ein an sich bekanntes Motorsteuergerät angegeben.In a step 100 takes place when stopping the engine of the motor vehicle, a storage of Wegstrecken- or Km-level of the odometer. The storage of the mileage takes place in a memory of an in-vehicle control unit, which has influence on the vehicle movement. As an example, a per se known engine control unit is given.

Bei einem Motorneustart erfolgt zunächst, wiederum in an sich bekannter Weise, eine Steuergerät-Initialisierung (Schritt 101). In einen anschließenden Schritt 102 wird der in dem Speicher des Steuergeräts gespeicherte Kilometerstand ausgelesen. In einem nachfolgenden Schritt 103 wird der aktuelle Kilometerstand des Wegstreckenzählers ausgelesen. Der aus dem Speicher des Steuergeräts ausgelesene Kilometerstand wird in einem Schritt 104 mit dem aktuellen Kilometerstand des Kilometerzählers verglichen. Der Vergleich kann beispielsweise durch das Steuergerät, in welchem die Speicherung des Kilometerstandes erfolgte, oder ein beliebiges anderes Steuergerät durchgeführt werden. Wird in dem Schritt 104 festgestellt, daß der aktuelle Kilometerstand dem gespeicherten Kilometerstand entspricht, insbesondere, daß der aktuelle Kilometerstand größer oder gleich dem gespeicherten Kilometerstand ist, kann davon ausgegangen werden, daß keine Manipulation des Wegstreckenzählers durchgeführt wurde, da derartige Manipulationen typischerweise zur Vortäuschung eines geringeren Kilometerstandes verwendet werden. In einem Schritt 105 erfolgt in diesem Fall eine Speicherung des aktuellen Kilometerstandes. Anschließend verzweigt das Verfahren von Schritt 105 zu einem Schritt 107, in welchem bewirkt wird, daß das normale Steuergeräte-Programm durchgeführt werden kann.When the engine is restarted, a control unit initialization takes place, again in a manner known per se (step 101). In a subsequent step 102, the mileage stored in the memory of the control unit is read out. In a subsequent step 103, the current odometer reading of the odometer read. The read out of the memory of the controller odometer reading is compared in a step 104 with the current odometer of the odometer. The comparison can be carried out for example by the control unit in which the storage of the mileage was carried out, or any other control unit. If it is determined in step 104 that the current mileage corresponds to the stored mileage, in particular, that the current mileage is greater than or equal to the stored mileage, it can be assumed that no manipulation of the odometer was performed, since such manipulations are typically for the purpose of pretending lower mileage can be used. In a step 105, a storage of the current mileage takes place in this case. Subsequently, the process branches from step 105 to a step 107, in which it is effected that the normal controller program can be performed.

Es sei angemerkt, daß auf den Schritt 105, d. h. eine Speicherung des aktuellen Kilometerstandes beim Motorneustart, verzichtet werden kann und lediglich bei einem weiteren Abstellen des Motors eine Speicherung des entsprechenden Kilometerstandes vorgesehen sein kann, wie sie bereits unter Bezugnahme auf Schritt 100 erläutert wurde.It should be noted that the step 105, d. H. a storage of the current mileage when the engine is restarted, can be dispensed with and a storage of the corresponding mileage can be provided only at a further shutdown of the engine, as has already been explained with reference to step 100.

Wird in dem Schritt 104 jedoch festgestellt, daß der aktuelle Kilometerstand dem gespeicherten Kilometerstand nicht entspricht, insbesondere kleiner als dieser ist, wird in einem Schritt 106 eine kundenspezifische Reaktion auf eine in diesem Falle angenommene Wegstreckenzählermanipulation ermöglicht. Das heißt, da in diesem Fall von einer Wegstreckenzählermanipulation ausgegangen werden muß, können verschiedene geeignete Maßnahmen, neben der Unterbindung der Motorfunktion des Kraftfahrzeugs beispielsweise die Auslösung eines Alarmsignals, eingeleitet werden. Nach Durchführung derartiger Maßnahmen ist auch hier eine Verzweigung zu dem Schritt 107, welcher die Durchführung eines normalen Steuergeräte-Programms ermöglicht, durchführbar.However, if it is determined in step 104 that the current mileage does not correspond to the stored mileage, in particular is less than this in a step 106, a custom response to an assumed odometer manipulation in this case is enabled. That is, since in this case an odometer manipulation must be assumed, various suitable measures can be initiated in addition to the inhibition of the motor function of the motor vehicle, for example the triggering of an alarm signal. After carrying out such measures, a branch to the step 107, which makes it possible to carry out a normal control program, can also be carried out here.

Es sei angemerkt, daß für den Fall, daß ein Cockpit bzw. ein Wegstreckenzähler oder ein Steuergerät (rechtmäßigerweise und vom Fahrzeughalter gewünscht) ausgetauscht werden muß, entsprechend Werkstatt-Werkzeuge vorzusehen sind, welche eine entsprechende Handhabung bzw. Beeinflussung des erfindungsgemäßen Verfahrens ermöglichen.It should be noted that in the event that a cockpit or an odometer or a control unit (legitimately and desired by the vehicle owner) must be replaced, workshop tools are accordingly provided, which allow appropriate handling or influencing the method according to the invention.

Das erfindungsgemäße Verfahren stellt einen einfachen und im wesentlichen ohne Mehrkosten bereitstellbaren Manipulationsschutz eines Wegstreckenzählers zur Verfügung. Zur wirksamen Durchführung einer Manipulation müßten gleichzeitig im Cockpit bzw. dem Wegstreckenzähler und im Steuergerät Änderungen vorgenommen werden; dies stellt einen gegenüber herkömmlichen Möglichkeiten deutlichen höheren und technisch schwierigeren Aufwand dar, und ist in effektiver Weise lediglich durch autorisierte Werkstätten, welche mit entsprechenden Werkzeugen ausgerüstet sind, durchführbar.The method according to the invention provides a simple manipulation protection of an odometer which can be provided essentially without additional costs. To effectively carry out a manipulation would have to be made simultaneously in the cockpit or the odometer and in the control unit changes; this represents a significantly higher and technically difficult effort compared to conventional options, and is effectively only by authorized repairers who are equipped with appropriate tools, feasible.

Eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung ist schematisch in Figur 2 dargestellt. Mit 1 und 2 sind hierbei ein erstes bzw. ein zweites Steuergerät bezeichnet. Die Steuergeräte 1, 2 sind über eine Datenaustauschleitung, beispielsweise eine Busleitung, miteinander verbunden. Wenigstens eines der Steuergeräte 1, 2 ist hierbei in der Lage, einen aktuellen Kilometerstand einzulesen und mit einem gespeicherten Kilometerstand zu vergleichen. Ferner ist wenigstens eines der Steuergeräte 1, 2 in der Lage, die gewünschte Reaktion, beispielsweise eine Unterbindung der Motorfunktion des Kraftfahrzeugs oder die Auslösung eines Alarm- oder Ortungssignals, einzuleiten.A preferred embodiment of the device according to the invention is shown schematically in FIG FIG. 2 shown. 1 and 2 hereby designate a first or a second control device. The control units 1, 2 are connected to one another via a data exchange line, for example a bus line. At least one of the control units 1, 2 is in this case able to read in a current mileage and compare it with a stored mileage. Furthermore, at least one of the control units 1, 2 is able to initiate the desired reaction, for example an inhibition of the engine function of the motor vehicle or the triggering of an alarm or locating signal.

Bei einem Anwendungsbeispiel wäre es möglich, das Steuergerät 1 beispielsweise durch das Kombiinstrument, und das Steuergerät 2 beispielsweise durch das Getriebe- oder Motorsteuergerät zu realisieren. Hierbei würde das Kombiinstrument 1 die Daten an das Getriebe- oder Motorsteuergerät 2 aussenden, welches die Daten miteinander vergleicht und eine entsprechende Reaktion einleitet.In an application example, it would be possible to implement the control unit 1, for example, by the instrument cluster, and the control unit 2, for example by the transmission or engine control unit. In this case, the instrument cluster 1 would send the data to the transmission or engine control unit 2, which compares the data with each other and initiates a corresponding reaction.

Es sei schließlich darauf hingewiesen, daß die beschriebene Vorrichtung auch in Form lediglich eines Steuergerätes oder auch in Form von mehr als zwei Steuergeräten realisiert sein kann.It should finally be noted that the device described can also be implemented in the form of only one control unit or in the form of more than two control units.
