Ferner weist der Fahrerraum 4 ein Armaturenbrett auf, das zu¬ mindest einen Tachographen 12 umfasst. Alternativ kann der Tachograph 12 ein eigenständiges Gerät sein, das an ein Ta¬ chometer 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. Further, 4 has the driver's compartment of a dashboard, the minimum to ¬ comprises a tachograph 12th Alternatively, the tachograph 12 may be an independent device that can be connected to a Ta ¬ chometer 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 ver¬ sorgt wird, können durch die Recheneinheit der Chipkarte Pro¬ gramme ausgeführt werden, die beispielsweise auf der Spei¬ chereinheit der Chipkarte CARD gespeichert sind. Alternativ zu der Chipkarte CARD kann auch ein anderer Datenträger mit oder ohne Recheneinheit verwendet werden. 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 entspre¬ chenden 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.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. Is if the smart card CARD suitable makes energy ver ¬, can be executed by the computing unit of the smart card Pro ¬ programs, which are for example, SpeI ¬ chereinheit the chip card CARD stored.

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 end time of entspre ¬ sponding ride. 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 i- dentifiziert werden (Figur 2). Das heißt in diesem Zusammenhang, dass der Tachograph 12 bzw. die Chipkarte CARD die Chipkarte CARD bzw. den Tachographen 12 dahingehend überprü¬ fen, 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). That is, in this context, that the tachograph 12 and the smart card CARD the chip card CARD or the tachograph fen 12 to the effect überprü ¬ whether the tachograph 12 and the smart card CARD are authentic, that is, in this context, that the chip card CARD or the tachograph 12 are not counterfeit and are intended by the legislature and / or the corresponding 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 been¬ det, so muss die Chipkarte CARD regelmäßig in der Datenträ¬ gervorrichtung angeordnet bzw. regelmäßig aus der Datenträ¬ gervorrichtung 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 Authenti¬ fizierung 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 a ride to the driver or change takes place, or if the drive ¬ been det are so must the chip card CARD regularly arranged in the gervorrichtung Datenträ ¬ or periodically removed from the gervorrichtung Datenträ ¬. 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 Authenti ¬ fication AUTH or identification the smart card CARD or the tachograph 12 is performed automatically.
Vorzugsweise 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.Preferably, 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 ab¬ stellen 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 Ak¬ tualisieren 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 allows the driver of the motor vehicle 2 at rest can put the motor vehicle 2 from ¬ , it may leave briefly and then still quickly his smart card CARD can be issued.
