The driving data recorder arrangement has means for detecting driving conditions of the vehicle and obtaining driving status data, driving state storing means for storing the driving status data, means for inputting driver data associated with a driving or driving section, driver data storing means for storing the driver data and memory accessing means for enabling a readout of Fahrzustands- and driver data from at least one journey section. The driver data input device has identification means for identifying the driver on the basis of physical characteristics, in particular during a driving state, and for outputting identification data.

Es ist Aufgabe der Erfindung, ein Verfahren zum Betreiben eines Datenträgers, der in einer Datenträgervorrichtung eines Tachographen angeordnet ist, zu schaffen, das einfach ein komfortables Verwenden eines digitalen Tachographen bzw. des Datenträgers ermöglicht.It is an object of the invention to provide a method for operating a data carrier which is arranged in a data carrier device of a tachograph, which allows easy convenient use of a digital tachograph or the data carrier.

Die erfindungsgemäße Aufgabe wird durch ein Verfahren zum Betreiben eines Datenträgers gemäß Anspruch 1 gelöst. Der Datenträger ist in einer Datenträgervorrichtung des Tachographen angeordnet. Ausgelöst durch einen Fahrzeugstopp des Kraftfahrzeugs wird der Tachograph automatisch authentifiziert und/oder identifiziert, wobei der Tachograph nach einer vorgegebenen ersten Zeitdauer nach dem Fahrzeugstopp des Kraftfahrzeugs mittels des Datenträgers automatisch authentifiziert und/oder identifiziert wird. Dies kann dazu beitragen, dass beim Anfordern des Datenträgers durch den Fahrer des Kraftfahrzeugs kurz nach dem Einschalten der Zündung des Kraftfahrzeugs oder kurz nach dem Fahrzeugstopp der Datenträger sehr schnell ausgegeben werden kann. Ferner ermöglicht dies die Authentifizierung bzw. Identifizierung des Tachographen. Der Datenträger ist vorzugsweise eine Chipkarte, deren Chip zumindest über eine Speichereinheit und vorzugsweise zumindest über eine Recheneinheit verfügt.The object of the invention is achieved by a method for operating a data carrier according to claim 1. The data carrier is arranged in a data carrier device of the tachograph. Triggered by a vehicle stop of the motor vehicle, the tachograph is automatically authenticated and / or identified, wherein the tachograph is automatically authenticated and / or identified after a predetermined first period of time after the vehicle stop of the motor vehicle by means of the data carrier. This can contribute to the fact that when requesting the data carrier by the driver of the motor vehicle shortly after switching on the ignition of the motor vehicle or shortly after the vehicle stop the disk can be issued very quickly. Furthermore, this allows the authentication or identification of the tachograph. The data carrier is preferably a chip card whose chip is at least a memory unit and preferably has at least one arithmetic unit.

Das Authentifizieren und/oder Identifizieren des Tachographen nach der vorgegebenen ersten Zeitdauer kann dazu beitragen, ein unnötiges Authentifizieren zu vermeiden, insbesondere bei einem kurzfristigen Fahrzeugstopp, beispielsweise an einer roten Ampel.Authenticating and / or identifying the tachograph after the predetermined first time period may help to avoid unnecessary authentication, especially at a short-term vehicle stop, for example at a red traffic light.

In einer vorteilhaften Ausgestaltung wird der Datenträger bzw. der Tachograph nach dem erfolgreichen Authentifizieren des Datenträgers bzw. des Tachographen für eine vorgegebene zweite Zeitdauer als authentisch behandelt. Dies ermöglicht, dass der Fahrer nicht unmittelbar nach dem Einschalten der Zündung des Kraftfahrzeugs bzw. nach dem Fahrzeugstopp den Datenträger anfordern muss und dennoch der Datenträger schnell ausgegeben wird. Dass der Datenträger als authentisch behandelt wird, bedeutet in diesem Zusammenhang, dass der Datenträger so behandelt wird, als ob die Authentifizierung zeitnah erfolgreich durchgeführt wurde.In an advantageous embodiment, the data medium or the tachograph is treated as authentic after the successful authentication of the data medium or the tachograph for a predetermined second period of time. This allows the driver does not have to request the disk immediately after switching on the ignition of the motor vehicle or after the vehicle stop and still the disk is issued quickly. In this context, the fact that the volume is treated as authentic means that the volume is treated as if the authentication was successful in a timely manner.

In einer weiteren vorteilhaften Ausgestaltung werden lediglich nach dem erfolgreichen Authentifizieren bzw. nach dem erfolgreichen Identifizieren automatisch Daten zwischen dem Tachographen und dem Datenträger ausgetauscht. Dies trägt dazu bei, dass keine Daten mit einem nicht authentifizierten bzw. nicht identifizierten Datenträger bzw. Tachographen ausgetauscht werden.In a further advantageous embodiment, data is automatically exchanged between the tachograph and the data carrier only after successful authentication or after successful identification. This contributes to the fact that no data is exchanged with an unauthenticated or unidentified data carrier or tachograph.

Ein Kraftfahrzeug 2 (Figur 1) umfasst einen Fahrerraum 4 und beispielsweise einen Anhänger 6. In dem Fahrerraum 4 sind zumindest ein Fahrzeugsitz 8 und ein Lenkrad 10 angeordnet. Ferner weist der Fahrerraum 4 ein Armaturenbrett auf, das zumindest einen Tachographen 12 umfasst. Alternativ kann der Tachograph 12 ein eigenständiges Gerät sein, das an ein Tachometer des Kraftfahrzeugs 2 anschließbar ist.A motor vehicle 2 ( FIG. 1 ) comprises a driver's compartment 4 and, for example, a trailer 6. At least one vehicle seat 8 and one steering wheel 10 are arranged in the driver's compartment 4. Furthermore, the driver's compartment 4 has a dashboard which comprises at least one tachograph 12. Alternatively, the tachograph 12 may be an independent device which can be connected to a tachometer of the motor vehicle 2.

Der Tachograph 12 weist eine Datenträgervorrichtung auf. Die Datenträgervorrichtung eignet sich zur Aufnahme eines Datenträgers. Der Datenträger ist bevorzugt eine Chipkarte CARD. Die Chipkarte CARD weist einen Computerchip auf, der bevorzugt zumindest eine Recheneinheit und eine Speichereinheit umfasst. Falls die Chipkarte CARD geeignet mit Energie versorgt wird, können durch die Recheneinheit der Chipkarte Programme ausgeführt werden, die beispielsweise auf der Speichereinheit der Chipkarte CARD gespeichert sind. Alternativ zu der Chipkarte CARD kann auch ein anderer Datenträger mit oder ohne Recheneinheit verwendet werden.The tachograph 12 has a data carrier device. The data carrier device is suitable for receiving a data carrier. The data carrier is preferably a chip card CARD. The chip card CARD has a computer chip which preferably comprises at least one arithmetic unit and one memory unit. If the chip card CARD is supplied with suitable energy, programs can be executed by the arithmetic unit of the chip card, which programs are stored, for example, on the memory unit of the chip card CARD. As an alternative to the chip card CARD, another data carrier with or without arithmetic unit can also be used.

Durch den Tachographen 12 können Fahrdaten bezüglich des Kraftfahrzeugs 2 auf der Chipkarte CARD gespeichert werden. Die Fahrdaten umfassen beispielsweise eine Fahrdauer, eine Fahrgeschwindigkeit und/oder Fahrzeiten. Die Fahrzeiten sind beispielsweise eine Startzeit oder eine Endzeit der entsprechenden Fahrt. Ferner können auf der Chipkarte beispielsweise Informationen über den Fahrer des Kraftfahrzeugs 2 gespeichert werden. Beispielsweise kann der Tachograph zwei Datenträgervorrichtungen umfassen, in die jeweils eine Chipkarte CARD des Fahrers bzw. eines Beifahrers des Kraftfahrzeugs 2 eingeführt werden können. Bei einem Fahrerwechsel werden die Chipkarten CARD dann bevorzugt ausgetauscht. Alternativ kann ein Schalter an dem Tachographen 12 vorgesehen sein, durch den von der Chipkarte CARD des Fahrers auf die Chipkarte CARD des Beifahrers umgeschaltet werden kann.Driving data relating to the motor vehicle 2 can be stored on the chip card CARD by the tachograph 12. The driving data include, for example, a driving time, a driving speed and / or driving times. The travel times are, for example, a start time or an end time of the corresponding trip. Furthermore, information about the driver of the motor vehicle 2 can be stored on the chip card, for example. For example, the tachograph may comprise two data carrier devices into each of which a chip card CARD of the driver or of a passenger of the motor vehicle 2 may be introduced. In a driver change the smart card CARD are then preferably replaced. Alternatively, a switch can be provided on the tachograph 12, by which the driver can change over from the smart card CARD of the driver to the smart card CARD of the passenger.

Bevor Daten zwischen der Chipkarte CARD und dem Tachographen 12 ausgetauscht werden dürfen, müssen die Chipkarte CARD und/oder der Tachograph 12 authentifiziert AUTH und/oder identifiziert werden (Figur 2). Das heißt in diesem Zusammenhang, dass der Tachograph 12 bzw. die Chipkarte CARD die Chipkarte CARD bzw. den Tachographen 12 dahingehend überprüfen, ob der Tachograph 12 bzw. die Chipkarte CARD authentisch sind, d. h. in diesem Zusammenhang, dass die Chipkarte CARD bzw. der Tachograph 12 keine Fälschungen sind und vom Gesetzgeber und/oder vom entsprechenden Hersteller für diesen Verwendungszweck vorgesehen sind.Before data may be exchanged between the chip card CARD and the tachograph 12, the chip card CARD and / or the tachograph 12 must be authenticated AUTH and / or identified ( FIG. 2 ). In this context, that means that the tachograph 12 or the chip card CARD check the chip card CARD or the tachograph 12 to determine whether the tachograph 12 or the chip card CARD are authentic, ie in this context that the chip card CARD or the Tachograph 12 are not forgeries and are intended by law and / or the appropriate manufacturer for this purpose.

Die Authentifizierung AUTH kann zwischen einigen Sekunden und wenigen Minuten dauern. Tritt nun der Fahrer eine Fahrt an oder findet der Fahrerwechsel statt oder wird die Fahrt beendet, so muss die Chipkarte CARD regelmäßig in der Datenträgervorrichtung angeordnet bzw. regelmäßig aus der Datenträgervorrichtung entfernt werden. Nach dem Anfordern der Chipkarte CARD durch den Fahrer wird zunächst die Chipkarte CARD bzw. der Tachograph 12 authentifiziert AUTH und/oder identifiziert und danach werden die Daten ausgetauscht. Damit der Fahrer nicht unnötig lange auf das Ausgeben der Chipkarte CARD warten muss, ist vorgesehen, dass ausgelöst durch ein Einschalten der Zündung IGN des Kraftfahrzeugs einer Brennkraftmaschine des Kraftfahrzeugs 2 und/oder ausgelöst durch einen Fahrzeugstopp STOPP des Kraftfahrzeugs 2 die Authentifizierung AUTH bzw. Identifizierung der Chipkarte CARD bzw. des Tachographen 12 automatisch durchgeführt wird.Authentication AUTH can take between a few seconds and a few minutes. If the driver now drives or the driver change takes place or the journey is terminated, the chip card CARD must be regularly arranged in the data carrier device or regularly removed from the data carrier device. After requesting the smart card CARD by the driver, the smart card CARD or the tachograph 12 is first authenticated AUTH and / or identified and then the data is exchanged. So the Driver does not have to wait unnecessarily long for the issuing of the smart card CARD is provided that triggered by turning on the ignition IGN of the motor vehicle of an internal combustion engine of the motor vehicle 2 and / or triggered by a vehicle stop STOP of the motor vehicle 2, the authentication AUTH or identification of the smart card CARD or the tachograph 12 is performed automatically.

Erfindungsgemäß wird nach dem Auslösen der Authentifizierung AUTH eine vorgegebene erste Zeitdauer DUR_1, beispielsweise ein bis fünf Minuten, gewartet, bis die Authentifizierung AUTH bzw. Identifizierung durchgeführt wird. Dies kann dazu beitragen, beispielsweise zu verhindern, dass bei einem Fahrzeugstopp STOPP an einer roten Ampel oder in einem Stau die Authentifizierung AUTH unnötig durchgeführt wird.According to the invention, after the triggering of the authentication AUTH, a predefined first time duration DUR_1, for example one to five minutes, is waited until the authentication AUTH or identification is carried out. This can help, for example, to prevent AUTH authentication from being unnecessarily performed when the vehicle is stopped at a red light or in a traffic jam.

Ferner wird bevorzugt die Authentifizierung AUTH nach dem Authentifizieren AUTH bzw. Identifizieren für eine vorgegebene zweite Zeitdauer DUR_2 aufrecht erhalten und die Chipkarte CARD als authentisch behandelt. Dies ermöglicht, dass der Fahrer des Kraftfahrzeugs 2 in Ruhe das Kraftfahrzeug 2 abstellen kann, es eventuell kurz verlassen kann und dann immer noch schnell seine Chipkarte CARD ausgegeben werden kann. Nach dem Authentifizieren AUTH der Chipkarte CARD bzw. des Tachographen 12 werden die Daten auf der Chipkarte CARD vorzugsweise automatisch aktualisiert UPD. Das automatische Aktualisieren UPD kann so auch zu einem beschleunigten Ausgeben der Chipkarte CARD beitragen.Furthermore, the authentication AUTH is preferably maintained after the authentication AUTH or identification for a predefined second time duration DUR_2 and the smart card CARD is treated as authentic. This makes it possible for the driver of the motor vehicle 2 to park the motor vehicle 2 at rest, possibly leave it for a short time, and then still be able to quickly output his chip card CARD. After authenticating AUTH the chip card CARD or the tachograph 12, the data on the chip card CARD is preferably updated automatically UPD. The automatic updating UPD can thus also contribute to an accelerated output of the chip card CARD.

Ein erstes Programm (Figur 3) zum Betreiben des Tachographen 12 ist vorzugsweise auf einem Speichermedium des Tachographen 12 abgespeichert. Das erste Programm dient dazu, die Chipkarte CARD automatisch zu authentifizieren AUTH und/oder zu identifizieren und die Authentifizierung AUTH während der zweiten Zeitdauer DUR_2 nach dem Authentifizieren AUTH aufrecht zu halten. Das erste Programm wird vorzugsweise zeitnah zu dem Einschalten der Zündung des Kraftfahrzeugs IGN des Kraftfahrzeugs 2 in einem Schritt S1 gestartet. In dem Schritt S1 werden gegebenenfalls Variablen initialisiert.A first program ( FIG. 3 ) for operating the tachograph 12 is preferably stored on a storage medium of the tachograph 12. The first program is used to automatically authenticate the smart card CARD AUTH and / or to authenticate AUTH during the second period DUR_2 after authenticating AUTH. The first program is preferably timely to turn on the ignition of the motor vehicle IGN of the Motor vehicle 2 started in a step S1. If necessary, variables are initialized in step S1.

In einem Schritt S2 wird für eine vorgegebene erste Zeitdauer DUR_1 verweilt. Die vorgegebene erste Zeitdauer DUR_1 kann beispielsweise ein bis fünf Minuten betragen.In a step S2, DUR_1 is dwelled for a predefined first time duration. The predefined first time duration DUR_1 can be, for example, one to five minutes.

In einem Schritt S3 wird die Chipkarte CARD aktiviert ACT.In a step S3, the chip card CARD is activated ACT.

In einem Schritt S6 wird eine Zeit CLK_AV seit dem Authentifizieren AUTH der Chipkarte CARD ermittelt, beispielsweise abhängig von einer Uhrzeit CLK.In a step S6, a time CLK_AV is determined since the authentication AUTH of the chip card CARD, for example, depending on a time CLK.

In einem Schritt S7 wird überprüft, ob die Zeit CLK_AV seit dem Authentifizieren AUTH kleiner ist als die zweite Zeitdauer DUR_2. Die zweite Zeitdauer DUR-2 kann beispielsweise zehn Minuten betragen. Ist die Bedingung des Schritts S7 erfüllt, so wird die Bearbeitung erneut in dem Schritt S6 fortgesetzt. Ist die Bedingung des Schritts S7 nicht erfüllt, so wird die Bearbeitung in einem Schritt S8 fortgesetzt.In a step S7, it is checked whether the time CLK_AV since the authentication AUTH is smaller than the second time duration DUR_2. The second time period DUR-2 may be ten minutes, for example. If the condition of step S7 is satisfied, the processing is continued again in step S6. If the condition of step S7 is not met, the processing is continued in step S8.

In dem Schritt S8 wird die Chipkarte CARD deaktiviert DEACT.In step S8, the chip card CARD is deactivated DEACT.

In einem Schritt S9 kann das erste Programm beendet werden.In a step S9, the first program can be ended.

Das Ablaufdiagramm des ersten Programms kann ohne Weiteres auf ein Ablaufdiagramm eines ersten Programms übertragen werden, das von der Recheneinheit der unter Energie gesetzten Chipkarte CARD abgearbeitet wird zum Authentifizieren AUTH des Tachographen 12. Das erste Programm der Chipkarte CARD wird beim Aktivieren der Chipkarte CARD in dem Schritt S3 des ersten Programms gestartet. In dem Schritt S4 wird der Tachograph 12 authentifiziert AUTH bzw. identifiziert und nicht die Chipkarte CARD. Das erste Programm der Chipkarte CARD wird vorzugsweise mit dem Deaktivieren DEACT der Chipkarte CARD beendet.The flow chart of the first program can be easily transferred to a flow chart of a first program, which is processed by the arithmetic unit of the energized smart card CARD for authenticating AUTH of the tachograph 12. The first program of the smart card CARD is in activating the smart card CARD in the Step S3 of started the first program. In step S4, the tachograph 12 is authenticated AUTH or identified and not the smart card CARD. The first program of the chip card CARD is preferably ended with the deactivation DEACT of the chip card CARD.

Zusätzlich zu dem ersten Programm ist vorzugsweise ein zweites Programm (Figur 4) auf dem Speichermedium des Tachographen 12 gespeichert. Das zweite Programm dient dazu, die Chipkarte CARD schnell ausgeben zu können. Das zweite Programm wird vorzugsweise bei einem Anfordern der Chipkarte CARD durch den Fahrer des Kraftfahrzeugs 2 in einem Schritt S10 gestartet. In dem Schritt S10 werden gegebenenfalls Variablen initialisiert.In addition to the first program, a second program is preferably ( FIG. 4 ) is stored on the storage medium of the tachograph 12. The second program is used to quickly output the chip card CARD. The second program is preferably started when the chip card CARD is requested by the driver of the motor vehicle 2 in a step S10. If necessary, variables are initialized in step S10.

In einem Schritt S11 wird überprüft, ob die Zeit CLK_AV seit dem letzten Authentifizieren AUTH kleiner ist als die vorgegebene zweite Zeitdauer DUR_2. Ist die Bedingung in dem Schritt S11 nicht erfüllt, so wird die Bearbeitung in einem Schritt S12 fortgesetzt. Ist die Bedingung des Schritts S11 erfüllt, so wird die Bearbeitung in einem Schritt S14 fortgesetzt.In a step S11, it is checked whether the time CLK_AV since the last authentication AUTH is smaller than the predetermined second time duration DUR_2. If the condition is not satisfied in step S11, the processing is continued in step S12. If the condition of step S11 is satisfied, the processing is continued in step S14.

In dem Schritt S12 wird die Chipkarte CARD aktiviert ACT.In step S12, the smart card CARD is activated ACT.

In einem Schritt S13 wird die Chipkarte CARD authentifiziert AUTH und/oder identifiziert.In a step S13, the chip card CARD is authenticated AUTH and / or identified.

In dem Schritt S14 werden abschließend FINAL automatisch die Daten auf der Chipkarte CARD aktualisiert UPD.Finally, in step S14, FINAL automatically updates the data on the chip card CARD UPD.

In einem Schritt S15 wird die Chipkarte CARD deaktiviert DEACT.In a step S15, the chip card CARD is deactivated DEACT.

In einem Schritt S16 kann das zweite Programm beendet werden.In a step S16, the second program can be ended.

Alternativ und/oder zusätzlich kann das zweite Programm auch auf der Recheneinheit der Chipkarte CARD abgearbeitet werden, wobei dann das Aktivieren ACT der Chipkarte CARD des Schritts S12 des zweiten Programms entfällt und als Auslöser zum Starten des zweiten Programms der Chipkarte CARD verwendet wird. Ferner entfällt der Schritt S15, wobei dann das Deaktivieren der Chipkarte CARD durch den Tachographen 12 in dem Schritt S16 der Auslöser für das Beenden des zweiten Programms ist. Ferner wird in dem Schritt S13 der dann der Tachograph 12 authentifiziert AUTH bzw. identifiziert.Alternatively and / or additionally, the second program can also be processed on the arithmetic unit of the chip card CARD, in which case the activation ACT of the chip card CARD of the step S12 of the second program is omitted and used as a trigger for starting the second program of the chip card CARD. Furthermore, step S15 is omitted, in which case deactivating the chip card CARD by the tachograph 12 in step S16 is the trigger for terminating the second program. Further, in step S13, then the tachograph 12 is authenticated AUTH or identified.

Die Erfindung ist nicht auf das angegebene Ausführungsbeispiel beschränkt. Beispielsweise kann der Tachograph 12 in jedem beliebigen Kraftfahrzeug mit oder ohne Anhänger 6 angeordnet sein. Ferner können das erste und das zweite Programm in ein Programm implementiert sein. Ferner kann lediglich der Tachograph 12 bzw. lediglich die Chipkarte CARD authentifiziert AUTH bzw. identifiziert werden.The invention is not limited to the specified embodiment. For example, the tachograph 12 may be arranged in any motor vehicle with or without trailer 6. Further, the first and second programs may be implemented in a program. Furthermore, only the tachograph 12 or only the chip card CARD can be authenticated AUTH or identified.
