Description

Die Erfindung betrifft eine Einrichtung in einem Fahrzeug zur Aufzeichnung von Fahrtrouteninformationen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device in a vehicle Recording of route information according to the generic term of the Claim 1.

In der nicht vorveröffentlichten Patentanmeldung DE-P 43 10 099.6 der Anmelderin wird eine Einrichtung für ein Nutzungsabrechnungssystem vorgeschlagen, das sich insbesondere für den Einsatz im Rahmen der Gebührenabrechnung für ein gebührenpflichtiges Wegstreckennetz (z.B. für die Autobahngebührenabrechnung) eignet. Diese Einrichtung zeichnet sich gegenüber bekannten anderen Abrechnungssystemen vor allem dadurch aus, daß die Gebührenabrechnung praktisch ausschließlich im Fahrzeug selbst stattfindet und keine Informationen über die von einem Fahrzeug benutzten gebührenpflichtigen Wegstrecken das Fahrzeug verlassen. Dies wird dadurch ermöglicht, daß im Fahrzeug jeweils eine Abrechnungseinrichtung mitgeführt wird, die von einem Wertguthaben, das auf einem mobilen Guthabenspeicher (z.B. Chipkarte) geführt ist und im voraus vom Fahrer an einer beliebigen Zahlstelle (z.B. Chipkartenautomat) käuflich erworben wurde, fortlaufend die jeweilige Gebühr entsprechend dem geltenden Tarif für den gerade benutzten Streckenabschnitt abbucht. Hierzu sind Tarifinformationen auf einer Speichereinheit der Einrichtung verfügbar. Um die Abrechnungseinrichtung mit den Informationen zu versorgen, die zu einer Erkennung des gerade benutzten gebührenpflichtigen Streckenabschnitts erforderlich sind, verfügt sie über ein Empfangssystem, mit dem z.B. von einem Satellitennavigationssystem oder einem Funkpeilsystem Informationen empfangen werden können, die der aktuellen geographischen Position des Fahrzeugs entsprechen oder diese mit Hilfe einer Recheneinheit der Einrichtung errechenbar machen. Weiterhin verfügt die Abrechnungseinrichtung über eine Speichereinheit, in der die geographischen Daten sogenannter Identifikationspunkte gespeichert sind, die eine eindeutige Identifizierung der einzelnen gebührenpflichtigen Wegstrecken des Streckennetzes ermöglichen. Über das Empfangssystem werden in regelmäßigen kurzen Abständen (z.B. jede Sekunde) die Daten der gerade aktuellen geographischen Fahrzeugposition mit hoher Genauigkeit (z.B. 100 m) ermittelt. Liegen diese ermittelten Positionsdaten hinreichend nahe an aufeinanderfolgenden Identifikationspunkten, dann kann daraus auf das Durchfahren des zugehörigen gebührenpflichtigen Wegstreckenabschnitts geschlossen werden und automatisch eine entsprechende Abbuchung vom Wertguthabenkonto der Chipkarte erfolgen. Obwohl diese Einrichtung die durchfahrenen geographischen Positionen des Fahrzeugs sehr genau ermittelt, ist sie von ihrem Sinn und Zweck ausdrücklich nicht darauf ausgelegt, derartige Positionsdaten dauerhaft zu speichern. In the unpublished patent application DE-P 43 10 099.6 the The applicant becomes a facility for a usage billing system proposed that is particularly suitable for use in the context of Billing for a toll route network (e.g. for highway toll billing). This facility draws compared to other known accounting systems from that the billing is practically exclusively in the vehicle itself takes place and no information about that from a vehicle used toll routes leave the vehicle. This is made possible in that in the vehicle Billing facility carried by a credit, the on a mobile credit memory (e.g. chip card) and in in advance by the driver at any paying agent (e.g. Smart card machine) was purchased, the respective one continuously Fee according to the applicable tariff for the currently used Debit the route section. For this purpose, tariff information is on a Storage unit of the facility available. To the billing facility to provide with the information that leads to a recognition of the currently used section of the route subject to charges are required, it has a reception system with which e.g. of a Satellite navigation system or a radio direction finding system information can be received, the current geographic position of the Correspond to the vehicle or this with the help of a computing unit Make the facility calculable. Furthermore, the Billing device via a storage unit in which the geographic data of so-called identification points are stored, which clearly identify the individual fee-based Allow routes of the route network. Via the receiving system the data at regular short intervals (e.g. every second) the current geographic vehicle position with high Accuracy (e.g. 100 m) determined. Are these determined Position data sufficiently close to successive ones Identification points, then can be used to drive through the associated route section subject to a fee and automatically a corresponding debit from the credit account of Chip card done. Though this facility is the most traveled geographic positions of the vehicle is determined very precisely, it is expressly not designed for the purpose of such Store position data permanently.

In der FR 26 12 319 wird eine Vorrichtung in einem Fahrzeug beschrieben, die es ermöglicht, zum Zwecke einer die Intensität der Nutzung eines Fahrzeugs berücksichtigenden Kostenberechnung auf einem z.B. als Chip-Karte ausgebildeten auswechselbaren Datenträger neben fahrzeugspezifischen Daten (z.B. Motordrehzahl, Kraftstoffverbrauch) auch Daten aufzuzeichnen, die die Fahrtstrecke identifizieren. In diesem Zusammenhang wird lediglich die Möglichkeit der Aufzeichnung der zurückgelegten Wegstrecke erwähnt. Es werden aber keine Anregungen gegeben, auch Daten zu erfassen und gegen ein Überschreiben gesichert zu speichern, die eine zuverlässige Aussage darüber erlauben, an welchem Ort sich das Fahrzeug während einer Fahrt zu einem beliebigen Zeitpunkt jeweils befunden hat.In FR 26 12 319 a device in a vehicle is described that it allows for the purpose of an intensity of use of a vehicle considering cost calculation on a e.g. trained as a chip card exchangeable data carriers in addition to vehicle-specific data (e.g. engine speed, Fuel consumption) also record data that identify the route. In this The only connection is the possibility of recording the distance traveled Distance mentioned. However, no suggestions are given to also collect data and save against overwriting, which is a reliable statement about the location of the vehicle during a trip at any time.

Auf dem auswechselbaren Datenspeicher können bereits Daten eingespeichert sein, die den Fahrer identifizieren, so daß diese durch eine Datenleseeinrichtung in die Vorrichtung eingelegen werden können. Darüber hinaus besteht die Möglichkeit. zu Prüfzwecken über eine an die Vorrichtung angeschlossene Tastatur zusätzliche, den Fahrer identifizierende Daten einzugeben, um einen Mißbrauch des Datenträgers durch Unbefugte auszuschließen. Nach erfolgter Abrechnung können die aufgezeichneten Daten wieder mit den Daten der nächsten Fahrt überschrieben werden.Data can already be stored on the exchangeable data storage device Identify drivers so that they can be read into the device by a data reading device can be inserted. There is also the possibility. for testing purposes a keyboard connected to the device additional identifying the driver Enter data to prevent misuse of the data carrier by unauthorized persons. After settlement, the recorded data can again be combined with the data from the next trip will be overwritten.

Die EP-A 0 508 405 beschreibt ein System zur Positionsbestimmung eines Fahrzeugs, das vorzugsweise auf der Nutzung eines Systems zur Satellitennavigation beruht. Um die Tagesfahrleistung eines kommerziell genutzten Fahrzeugs (z.B. Taxi) möglichst genau und mit wenig gerätetechnischem Aufwand erfassen zu können, sieht dieses System im Fahrzeug jeweils ein einfaches Gerät vor, das den Empfang von Satellitensignalen und die Speicherung dieser Daten mit zugeordneten Zeitinformationen in digitalisierter Form auf einer Chip-Karte ermöglicht. Zur regelmäßigen Auswertung können die aufgezeichneten Daten aus der Chip-Karte in einen fahrzeugexternen Rechner ausgelesen werden, der über ein Auswertungsprogramm die sich aus den Satellitensignalen errechenbaren Fahrzeugpositionsdaten sowie die sich daraus ergebenden Fahrtstrecken ermittelt und auf diese Weise die Fahrleistung bestimmt. Eine gegenüber Überschreiben gesicherte Datenaufzeichnung wird ebensowenig erwogen wie die Aufzeichnung von Daten, die eine eindeutige Identifizierung des Fahrer ermöglichen würden.EP-A 0 508 405 describes a system for determining the position of a vehicle preferably based on the use of a system for satellite navigation. To the Daily mileage of a commercially used vehicle (e.g. taxi) as accurate and This system sees in the Vehicle each have a simple device that receives satellite signals and the Storage of this data with assigned time information in digitized form a chip card. The recorded data can be used for regular evaluation Data from the chip card can be read into a computer external to the vehicle an evaluation program that can be calculated from the satellite signals Vehicle position data and the resulting routes are determined and on this way determines the mileage. A secured against overwriting Data recording is no more considered than the recording of data that a would allow clear identification of the driver.

Die EP-A 0 189 204 bezieht sich auf ein für Nutzfahrzeuge vorgesehenes fahrzeuginternes Gerät zur Aufzeichnung von wesentlichen Betriebsparametern des Fahrzeugeinsatzes auf einem mobilen Speichermedium, z.B. auf einer Chip-Karte. Dieses Speichermedium kann in eine externe Recheneinrichtung eingelesen werden, so daß die aufgezeichneten Daten für Zwecke der Verwaltung (z.B. Kostenabrechnung) oder Fahrzeugwartung zur Auswertung zur Verfügung stehen. Eine gegen Überschreiben gesicherte Aufzeichnung von Daten zur eindeutigen Identifizierung des Fahrers des Fahrzeugs und der Orte, an denen sich das Fahrzeug zu beliebigen Zeitpunkten befunden hat, wird nicht erwogen.EP-A 0 189 204 relates to an internal vehicle intended for commercial vehicles Device for recording essential operating parameters of vehicle use a mobile storage medium, e.g. on a chip card. This storage medium can be used in an external computing device can be read so that the recorded data for Administration purposes (e.g. cost accounting) or vehicle maintenance for evaluation To be available. A recording of data saved against overwriting clear identification of the driver of the vehicle and the places where that Vehicle has been found at any time is not considered.

In der EP-A 0 191 413 wird ein Fahrtschreiber vorgeschlagen, bei dem analog zu der üblichen Diagrammscheibenregistrierung die Fahrtstrecken und Fahrgeschwindigkeiten auf einem elektronischen Speichermedium aufgezeichnet werden, das als mobile Datenkarte ausgebildet ist und in das den Fahrer identifizierende Daten eingeprägt sind. Eine irgendwie geartete Erfassung geografischer Ortspositionen des Fahrzeugs ist nicht vorgesehen. Eine in den Fahrtschreiber integrierte Druckereinheit ermöglicht das Ausdrucken eines tabellarischen Fahrtprotokolls mit den Arbeitszeit- und Fahrtdaten des Fahrers.EP-A 0 191 413 proposes a tachograph in which, analogously to the usual diagram disc registration the driving distances and driving speeds an electronic storage medium that is recorded as a mobile data card is formed and in which data identifying the driver are stamped. Somehow It is not intended to record geographic locations of the vehicle. A printer unit integrated in the tachograph enables the printing of a Tabular trip log with the driver's working hours and trip data.

Aus der US 5 016 206 ist ein elektronisches Aufzeichnungsgerät für Müllfahrzeuge bekannt, mit dem jeweils die Ortsposition des Müllfahrzeugs sowie zugeordnete Zeitinformationen gespeichert werden, wenn das Müllfahrzeug einen Vorgang zum Auf- oder Abladen von Müll ausführt. Zur Ermittlung der Ortsposition ist das Gerät mit einer Einrichtung zum Empfang von Signalen eines Navigationssenders (z.B. Navigationssatellitensystem) ausgestattet. Eine schreibgeschützte Aufzeichnung von Daten, die den Fahrer eindeutig identifizieren, sowie von Daten, die eine exakte Identifizierung der Fahrzeugposition zu einem beliebigen Zeitpunkt zum Zwecke der Verkehrskontrolle ermöglichen würden, ist nicht vorgesehen. An electronic recording device for refuse collection vehicles is known from US Pat. No. 5,016,206. with the location of the garbage truck and assigned time information be saved when the garbage truck has an operation to load or unload garbage executes. To determine the location, the device has a device for reception of signals from a navigation transmitter (e.g. navigation satellite system). A read-only recording of data that uniquely identify the driver, as well of data that accurately identify the vehicle position to any Time for traffic control purposes is not provided.

Aus der DE 38 29 725 Al ist eine Einrichtung zur Aufzeichnung von Fahrtrouteninformationen bekannt, die als Navigationsvorrichtung für Kraftfahrzeuge eingesetzt wird. Diese Einrichtung besitzt zur momentanen Standortbestimmung ein Empfangssystem für die Satellitennavigation (GPS-System). Darüber hinaus weist es einen Speicher mit digitalisierten Landkarten und einen z.B. als Chipkarte (IC-Karte) ausgebildeten Datenträger zur Speicherung von Fahrtroutendaten auf. Eine Recheneinheit ermittelt die Daten der tatsächlich vom Fahrzeug benutzten Fahrtroute und veranlaßt die Speicherung auf dem Datenträger, wobei auch Informationen zur verbrauchten Fahrtzeit mit abgespeichert werden können. Um die Menge der gespeicherten Daten auf ein Minimum zu beschränken, sieht diese Einrichtung vor, daß lediglich identifizierende Indexnummern von einzelnen Landkarten (Landkartennummer) und den darin enthaltenen Wegen (Wegnummern) sowie von sogenannten Knotenpunkten (z.B. Wegabzweigungen) zur Speicherung herangezogen werden, wenn diese Stellen vom Fahrzeug tatsächlich passiert worden sind. Es erfolgt keine Aufzeichnung, solange die aktuellen Werte der Landkarten-Nr. und der Weg-Nr. unverändert bleiben.DE 38 29 725 A1 describes a device for recording Route information known as a navigation device for Motor vehicles is used. This facility currently has Positioning a receiving system for satellite navigation (GPS system). In addition, it has a memory with digitized Maps and a e.g. trained as a chip card (IC card) Data carrier for storing route data. A computing unit determines the data of the route actually used by the vehicle and causes storage on the data carrier, whereby also Information about the travel time used can also be saved can. To keep the amount of data stored to a minimum restrict, this facility provides that only identifying Index numbers of individual maps (map number) and the ones in them included routes (route numbers) and so-called nodes (e.g. Branches) can be used for storage if these locations have actually been passed by the vehicle. There is no Recording as long as the current values of the map no. and the Route no. remain unchanged.

Diese bekannte Einrichtung dient allein als Navigationshilfe für den Fahrzeugführer und soll diesem verbesserte und aussagefähigere Informationen (z.B. hinsichtlich der verbleibenden Fahrzeit bis zum Ziel) liefern, wenn er dieselbe Route erneut befährt. Für verkehrsrechtliche Überwachungsaufgaben ist diese Einrichtung nicht vorgesehen. Es werden keine Aussagen darüber gemacht, ob der Datenträger zur Aufzeichnung der Fahrtrouteninformationen anders als die übrigen Komponenten etwa nicht fest in die Einrichtung eingebaut, sondern in leicht auswechselbarer Form angeordnet ist.This known device serves only as a navigation aid for the Driver and should this improved and more meaningful Information (e.g. regarding the remaining travel time until Destination) if he follows the same route again. For This facility is not a traffic monitoring task intended. No statements are made as to whether the disk to record the route information differently than the others Components, for example, are not permanently installed in the facility, but rather is arranged in an easily replaceable form.

Insbesondere im Rahmen gewerblich durchgeführter Transporte besteht vielfach der Wunsch, die von einem Fahrzeug zurückgelegten Wegstrecken nicht nur quantitativ (Länge), sondern auch qualitativ (Streckenführung) im Sinne eines Fahrtenbuchs zu erfassen und darüber hinaus zweifelsfrei festzuhalten, wer das Fahrzeug jeweils gefahren hat. Beispielsweise können für spezielle Gefahrguttransporte (z.B. Transport von von denen nicht abgewichen werden darf. Ein Nachweis hierüber ist heute sehr aufwendig, da er den Einsatz von entsprechendem Überwachungspersonal im jeweiligen Fahrzeug oder sogar von Begleitfahrzeugen erfordert.In particular in the context of commercial transports often the desire to cover the distances covered by a vehicle not only quantitatively (length), but also qualitatively (route) in the sense of a logbook and beyond that beyond doubt to record who drove the vehicle. For example can be used for special dangerous goods transports (e.g. transport of from which it is not allowed to deviate. Evidence of this is today very expensive, since he uses appropriate Surveillance personnel in the respective vehicle or even from Support vehicles required.

Umgekehrt gibt es geographische Zonen (z.B. Trinkwasserschutzgebiete), in denen Fahrzeuge mit wassergefährdender Ladung (z.B. Tankfahrzeuge) generell nicht verkehren dürfen. Ein Verstoß gegen entsprechende Vorschriften kann bisher nur dann festgestellt werden, wenn er von (zufällig) am Ort tätigem Uberwachungspersonal bemerkt wird.Conversely, there are geographical zones (e.g. drinking water protection areas), in which vehicles with water-polluting cargo (e.g. tank vehicles) generally not allowed to operate. A violation of the corresponding So far, regulations can only be determined if it is from (randomly) surveillance personnel working on site is noticed.

Weiterhin ist festzustellen, daß gerade die Betreiber größerer Fuhrparks (z.B. Speditionen) ein Interesse daran haben, den wirtschaftlichen Einsatz ihrer Transportkapazitäten möglichst gut zu steuern und zu überwachen (Fuhrparkmanagementsysteme). Dafür stehen bisher, was den eigentlichen Betrieb der Fahrzeuge angeht, im wesentlichen nur die aus den gesetzlich für Nutzkraftfahrzeuge vorgeschriebenen Fahrtschreibern hervorgehenden Daten zur Verfügung, die auf Diagrammscheiben aufgezeichnet werden. Eine Rekonstruktion der tatsächlich vom Fahrzeug benutzten einzelnen Wegstrecken ist daraus nicht möglich.It should also be noted that it is precisely the operators of larger fleets (e.g. freight forwarders) have an interest in the economic Use and manage their transport capacities as well as possible monitor (fleet management systems). So far, what stand for actual operation of the vehicles, essentially only from the tachographs required by law for commercial vehicles resulting data available on chart slices to be recorded. A reconstruction of the vehicle actually used individual routes is not possible.

Aufgabe der Erfindung ist es, eine Einrichtung der gattungsgemäßen Art dahingehend weiterzubilden, daß die von einem Fahrzeug benutzten Fahrtrouten nachträglich ohne großen Aufwand rekonstruiert werden können und eindeutige Informationen festgehalten werden, die den Nachweis ermöglichen, wer das Fahrzeug zu welchem Zeitpunkt bzw. an welchem 0rt gerade gefahren hat.The object of the invention is to provide a device of the generic type to further develop that used by a vehicle Routes can be subsequently reconstructed with little effort and clear information can be recorded that the Provide proof of who the vehicle is and at what time which 0rt just drove.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen 2 bis 13 angegeben. This task is solved by the characteristic features of the Claim 1. Advantageous developments of the invention are in the subclaims 2 to 13 indicated.

Durch die Erfindung wird die automatische Führung eines "elektronischen Fahrtenbuchs" geschaffen, in das alle Fahrten eines Fahrzeugs in einer Weise eingetragen werden, die eine nachträgliche Rekonstruktion der Streckenführung während der Fahrt zuläßt. Hierzu wird im Fahrzeug eine Einrichtung mitgeführt, die als kompaktes Gerät oder auch als verteilte, informationstechnisch miteinander verbundene Baugruppen im Fahrzeug installiert ist. Wesentlicher Teil der Einrichtung ist ein Empfangssystem, mit dem drahtlos gesendete Informationen empfangen werden können, die eine exakte Ermittlung der gerade vom Fahrzeug erreichten geographischen Position ermöglichen (z.B. anhand der Signale eines Satellitennavigationssystems wie GPS oder GLONASS) oder bereits selbst schon Positionsdaten darstellen (z.B. bei Funkpeilsystem). Auch im Rahmen eines zellular aufgebauten Mobilfunknetzes ließen sich genaue Ortsbestimmungen durchführen. Als besonders bevorzugt wird die Nutzung eines Satellitennavigationssystems angesehen. In diesem Fall ist die erfindungsgemäße Einrichtung auch mit einer Recheneinheit ausgestattet, die eine Berechnung der jeweiligen Positionsdaten anhand der empfangenen Satelliteninformationen ermöglicht. Als weitere wesentliche Baueinheit ist eine Speichereinrichtung vorgesehen, die eine Aufzeichnung der digitalisierten geographischen Fahrzeugpositionsdaten auf einem Datenträger ermöglicht. Letzterer ist leicht auswechselbar und gegen ein Überschreiben von bereits aufgezeichneten Daten geschützt, um unzulässige nachträgliche Manipulationen am gespeicherten Datenbestand auszuschließen. Hierzu kann darüber hinaus eine Verschlüsselung der aufgezeichneten Informationen erfolgen, die zweckmäßigerweise auch noch mit einer Komprimierung der Datenaufzeichnung verbunden werden kann. Letzteres hat den zusätzlichen Vorteil, daß die Kapazität des benutzten Datenträgers wesentlich erhöht wird. Als Datenträger können beispielsweise Speicher auf magnetischer Basis wie etwa Disketter eingesetzt werden. Besonders geeignet sind optische Speichermedien (compact disk), wobei solche mit nur einmaliger Beschreibbarkeit (WORM) bevorzugt werden.The invention automatically guides an "electronic Logbook "created, in which all trips of a vehicle in one Be entered in a way that a subsequent reconstruction of the Allows routing while driving. For this purpose, a Device carried as a compact device or as a distributed, Assemblies in the vehicle that are interconnected in terms of information technology is installed. An essential part of the facility is a Reception system that receives information transmitted wirelessly can be an exact determination of the straight from the vehicle enable the geographical position reached (e.g. based on the signals a satellite navigation system such as GPS or GLONASS) or already display position data itself (e.g. with radio direction finding system). Also within the framework of a cellularly constructed cellular network, precise Carry out local determinations. Use is particularly preferred of a satellite navigation system viewed. In this case it is The device according to the invention is also equipped with a computing unit, a calculation of the respective position data based on the received Allows satellite information. As another essential structural unit a memory device is provided which records the digitized geographic vehicle position data on one Allows disk. The latter is easily exchangeable and against one Protected to overwrite already recorded data inadmissible subsequent manipulation of the stored data to exclude. In addition, encryption of the recorded information take place, which is also expedient can be combined with a compression of the data recording. The latter has the additional advantage that the capacity of the used Disk is increased significantly. Can as a disk for example, magnetic-based memories such as diskettes be used. Optical storage media are particularly suitable (compact disk), with those that can only be written once (WORM) to be favoured.

Neben den rein geographischen Positionsdaten werden von der Speichereinrichtung auch die zugehörigen Zeitinformationen (Uhrzeit, Datum) aufgezeichnet. Die Positionsdaten werden von der Einrichtung vorzugsweise in regelmäßigen Zeitabständen ermittelt (z.B. alle 5 bis 10 Sekunden). Alternativ wäre auch eine fahrwegabhängige Positionsermittlung (z.B. alle 100 m) möglich. Insbesondere im ersten Fall, der einen festen Zeittakt vorsieht, ist es selbstverständlich nicht notwendig, zu jedem Positionsdatum auch eine Zeitinformation abzuspeichern. Es wäre beispielsweise möglich, aufgrund einer Aufzeichnung des Beginnzeitpunktes einer Fahrt die jeweils zugehörigen Zeitpunkte für die einzelnen Positionsdaten anhand des Zeittaktes zu errechnen. Die Zeitinformation selbst kann durch eine in die erfindungsgemäße Einrichtung integrierte Uhr oder auch durch ein entsprechendes Sendesignal von außen erhalten werden.In addition to the purely geographical position data, the Storage device also the associated time information (time, Date). The location data is provided by the facility preferably determined at regular intervals (e.g. every 5 to 10 Seconds). Alternatively, it would also be a route-dependent one Position determination (e.g. every 100 m) possible. Especially in the first If there is a fixed time, it goes without saying not necessary, also time information for each item date save. For example, it would be possible due to a Recording of the start time of a trip, the respective associated Points in time for the individual position data based on the timing calculate. The time information itself can be entered into the device integrated clock or by a corresponding transmission signal can be obtained from the outside.

Darüber hinaus ist die erfindungsgemäße Einrichtung zusätzlich mit einer Datenleseeinrichtung ausgestattet, die es erlaubt, Daten einzugeben, die eine Identifizierung des Fahrers des Fahrzeugs gewährleisten. Diese Daten werden ebenfalls auf dem Datenträger aufgezeichnet, der die Fahrtrouteninformationen speichert. Für eine solche Datenleseeinrichtung kommt insbesondere ein Chipkartenleser in Frage. Zur Vermeidung möglicher Mißbräuche kann eine zusätzliche Identifizierung beispielsweise über eine mittels einer entsprechenden Tastatur eingegebenen persönlichen Identifikationsnummer (PIN) oder über einen Fingerabdruckleser oder eine Stimmidentifizierungseinrichtung vorgesehen werden.In addition, the device according to the invention is additionally equipped with a Data reader equipped to allow data to be entered ensure identification of the driver of the vehicle. This Data is also recorded on the disk that contains the It saves route information. For such a data reading device a chip card reader is particularly suitable. To avoid Possible misuse can provide additional identification for example using a keyboard entered personal identification number (PIN) or via a Fingerprint reader or a voice identification device provided will.

Bei einer Überprüfung des Fingerabdrucks oder der Stimme des Fahrers könnte selbstverständlich auch auf eine Chipkarte verzichtet werden, wenn die Identifizierungsdaten in einem entsprechenden Datenspeicher der erfindungsgemäßen Einrichtung zuvor einmal gespeichert wurden.When checking the driver's fingerprint or voice could of course also be dispensed with a chip card, if the identification data in a corresponding data storage of the device according to the invention were previously stored once.

In vorteilhafter Weiterbildung der Erfindung kann die Einrichtung mit einer Schnittstelle versehen werden, über die aktuelle Daten des Fahrzeugbetriebs zur Aufzeichnung in die Speichereinrichtung gegeben werden können. Die zusätzlich aufgezeichneten Daten können sich beispielsweise auf die Fahrzeuggeschwindigkeit, den aktuellen Kraftstoffverbrauch, die Motordrehzahl oder ähnliche Größen beziehen. Dadurch werden beispielsweise Auswertungen möglich, die die Grundlage für eine bessere wirtschaftliche Nutzung des Verkehrsmittels bieten. Eine weitere Schnittstelle kann vorgesehen sein, über die die aufgezeichneten oder aufzuzeichnenden Daten (insbesondere die Positionsdaten) fortlaufend oder in bestimmten zeitlichen Abständen (z.B. alle 5 Minuten) mittels einer im Fahrzeug mitgeführten Kommunikationseinrichtung, vorzugsweise ein Mobiltelefon nach dem GSM-Standard, an eine Empfangsstelle (z.B. Betriebshof einer Spedition) zur Auswertung übermittelt werden. Dadurch wird beispielsweise eine externe gezielte Beeinflussung der zu wählenden Fahrtroute des Fahrzeugs ermöglicht. Für polizeiliche Überprüfungszwecke kann, ähnlich wie die Diagrammscheibe eines Fahrtschreibers, der Datenträger aus der erfindungsgemäßen Einrichtung herausgenommen und zur Überprüfung in einem geeigneten Lesegerät gelesen werden. Hierzu verfügt dieses Lesegerät über eine digitalisierte Straßennetzkarte, so daß die Fahrtroute genau nachvollzogen werden kann, indem die aufgezeichneten Positionsdaten mit den gespeicherten Daten des Straßennetzes verglichen werden. Anstelle eines Herausnehmens des Datenträgers könnte aber auch eine entsprechende Schnittstelle vorgesehen sein, die ein Auslesen der gespeicherten Daten ermöglicht.
Um den Fahrer rechtzeitig zum Austausch eines fast verbrauchten (d.h. weitgehend voll beschriebenen) Datenträgers gegen einen Datenträger mit ausreichend freier Speicherkapazität aufzufordern, damit ein Verlust von Daten vermieden wird, sollte die erfindungsgemäße Einrichtung mit einer geeigneten Signaleinrichtung versehen sein, die softwaremäßig angesteuert wird und den Fahrer warnt, wenn die Kapazitätsgrenze bald erreicht zu werden droht.
In an advantageous development of the invention, the device can be provided with an interface via which current data of the vehicle operation can be sent to the storage device for recording. The additionally recorded data can relate, for example, to the vehicle speed, the current fuel consumption, the engine speed or similar variables. This enables, for example, evaluations that provide the basis for better economic use of the means of transport. A further interface can be provided, via which the recorded or to be recorded data (in particular the position data) continuously or at certain time intervals (for example every 5 minutes) to a receiving point by means of a communication device carried in the vehicle, preferably a cell phone according to the GSM standard (eg depot of a shipping company) for evaluation. This enables, for example, an external targeted influencing of the route of the vehicle to be selected. For police checking purposes, similar to the chart of a tachograph, the data carrier can be removed from the device according to the invention and read in a suitable reading device for checking. For this purpose, this reading device has a digitized road network map, so that the route can be followed exactly by comparing the recorded position data with the stored data of the road network. Instead of removing the data carrier, a corresponding interface could also be provided, which enables the stored data to be read out.
In order to prompt the driver to replace an almost used (ie largely fully described) data carrier with a data carrier with sufficient free storage capacity so that loss of data is avoided, the device according to the invention should be provided with a suitable signaling device which is controlled by software and which Driver warns if the capacity limit threatens to be reached soon.

Durch das nachfolgende Beispiel wird die Erfindung näher erläutert:The invention is explained in more detail by the following example:

In einem Fahrzeug einer Spedition befindet sich ein erfindungsgemäßes Fahrtroutenaufzeichnungsgerät, das in Abständen von 5 Sekunden die geographische Position des Fahrzeugs über das Satellitennavigationssystem GPS errechnet. Die digitalisierten Positionskoordinaten werden zusammen mit dem jeweiligen Zeitpunkt, zu dem die Ortsinformationen angefallen sind, auf einem mobilen Datenträger in Form einer CD-WORM abgespeichert. Zusätzlich zu dieser Information werden über eine Schnittstelle die Fahrzeuggeschwindigkeit und der aktuelle Kraftstoffverbrauch erfaßt und ebenfalls abgespeichert. Um die aufgezeichneten Daten auf den Fahrer des Fahrzeugs beziehen zu können, wird dem Gerät vor Fahrtbeginn über einen Chipkartenleser die Identität des Fahrers mitgeteilt, die aus den Daten auf einer dem betreffenden Fahrer gehörenden Chipkarte hervorgeht. Der Datenträger für die Aufzeichnung der Fahrtrouteninformationen ist leicht auswechselbar und besitzt ein großes Speichervolumen. Da die Fahrtroute in der Regel vor Antritt der Fahrt bekannt ist, kann der Speicherbedarf rechtzeitig abgeschätzt werden und ein geeigneter Datenträger mit ausreichender freier Kapazität verwendet werden, so daß auf jeden Fall die gesamte Fahrt dokumentiert wird. Falls dennoch Speicherplatzprobleme auftreten sollten, kann durch eine entsprechende Softwareroutine rechtzeitig eine Warnung generiert werden, die den Fahrer auffordert, den fast ganz beschriebenen Datenträger herauszunehmen und durch einen leeren Datenträger zu ersetzen. Die abgespeicherten Daten können nach Abschluß der Fahrt archiviert werden und bei Bedarf mit einer digitalisierten Straßenkarte verglichen werden. Dieser Vergleich kann durch eine entsprechende Software graphisch aufbereitet werden und als Hardcopy archiviert werden.A vehicle according to the invention is located in a vehicle of a freight forwarder Route recording device that the at 5-second intervals geographical position of the vehicle over the Satellite navigation system GPS calculated. The digitized Position coordinates are added together with the respective time the location information has accumulated on a mobile data carrier saved in the form of a CD WORM. In addition to this information the vehicle speed and the current fuel consumption recorded and also saved. To the to be able to relate recorded data to the driver of the vehicle, the device is verified by a chip card reader before the start of the journey of the driver communicated from the data on one of the concerned Driver-owned chip card emerges. The disk for the Recording the route information is easily interchangeable and has a large storage volume. Because the route usually precedes When the journey begins, the memory requirement can be met in good time can be estimated and a suitable disk with sufficient free capacity can be used, so that definitely the whole Trip is documented. If you still have space problems should, by means of a corresponding software routine, a Warning generated that prompts the driver to almost entirely remove the data medium described and insert an empty one To replace disk. The saved data can after completion the trip can be archived and if necessary with a digitized Road map to be compared. This comparison can be made by a Appropriate software can be prepared graphically and as a hard copy be archived.

In Weiterbildung der Erfindung ist vorgesehen, daß durch eine zusätzliche Schnittstelle zu einem Mobilfunktelefon nach dem GSM-Standard die erfaßten Daten (zusätzlich zur Speicherung) an den zentralen Betriebshof der Spedition geschickt werden. Dort werden sie einer Auswertung zugänglich gemacht, so daß gegebenenfalls auf den Verlauf der Fahrt Einfluß genommen werden kann. Beispielsweise könnte über eine solche Schnittstelle ein Gefahrenguttransport in seiner Fahrtroute abhängig von der aktuellen Verkehrslage gesteuert werden. Die GPS- und GSM-Funktionen sind vorteilhaft in einem Gerät zusammengefaßt. Um zu vermeiden, daß die Identität des Fahrers zu seinem Nachteil verfälscht wird, da er unter Umständen für Schäden, die während der Fahrt entstehen, haftet, muß der Fahrer, dem die Chipkarte gehört, durch die Eingabe eines PIN-Codes über eine Tastatur vor Antritt der Fahrt seine Identität nachweisen. Dadurch wird verhindert, daß ein Unberechtigter mit einer Chipkarte fährt, die sich nicht rechtmäßig in seinem Besitz befindet. Damit die aufgezeichneten Daten nicht manipuliert werden können, werden sie in verschlüsselter Form abgespeichert. Gleichzeitig wird zur Reduktion des Datenvolumens eine geeignete Komprimierung angewendet. Der Datenträger ist von vornherein nur einmal beschreibbar (WORM), so daß nachträgliche Manipulationen ausgeschlossen sind. Eine Manipulation an der Schnittstelle zum Ortsdatenerfassungssystem oder an den übrigen Schnittstellen wird durch entsprechende Verplombungsmaßnahmen verhindert. Um eine Kontrolle des Fahrzeugs während der Fahrt durch die Polizei zu ermöglichen, ist eine zusätzliche Schnittstelle am Gerät vorgesehen, die ein schnelles Auslesen der Daten zur Fahrthistorie ermöglicht. In a development of the invention it is provided that by a additional interface to a mobile phone after GSM standard to the recorded data (in addition to storage) central shipping depot. There they will made accessible to an evaluation, so that, if necessary, on the Course of the trip can be influenced. For example a dangerous goods transport in his Route can be controlled depending on the current traffic situation. The GPS and GSM functions are advantageously combined in one device. To avoid the driver's identity to his disadvantage is falsified as it may be responsible for damage caused during the The driver who owns the chip card must go through entering a PIN code using a keyboard before starting the journey to prove one's identity. This prevents a Unauthorized person drives with a chip card that is not lawfully in is in his possession. So that the recorded data is not can be manipulated, they are encrypted saved. At the same time, to reduce the data volume appropriate compression applied. The disk is from the start writable only once (WORM), so that subsequent manipulation excluded are. A manipulation at the interface to Location data acquisition system or at the other interfaces is through appropriate sealing measures prevented. To control the Enabling the vehicle while driving by the police is one additional interface provided on the device, which is a fast Read out the data on the trip history.

Bei der aus der DE 38 28 725 Al bekannten Navigationseinrichtung werden die Fahrtrouteninformationen systembedingt nur für ganz bestimmte Punkte einer Fahrtroute aufgezeichnet. Das bedeutet, daß ein Abweichen von einer vorgegebenen Fahrtroute, beispielsweise das vorübergehende Befahren von Feldwegen, die nicht in der digitalisierten Straßenkarte verzeichnet sind, ebenso unbemerkt bleiben kann wie ein unzulässiges Verweilen an einer beliebigen Stelle zwischen zwei (fest vorgegebenen) Aufzeichnungspunkten. Die erfindungsgemäße Einrichtung schließt diese Lücken problemlos.In the navigation device known from DE 38 28 725 A1 the route information is system-specific only for very specific ones Points of a route recorded. That means a departure from a given route, for example the temporary one Driving on dirt roads that are not in the digitized road map listed, can remain as unnoticed as an inadmissible one Linger anywhere between two (fixed) Recording points. The device according to the invention closes this Gaps easily.
