Description

Stand der TechnikState of the art

Die Erfindung bezieht sich auf ein Zugangssystem, insbesondere für Kraftfahrzeuge.The invention relates to an access system, in particular for motor vehicles.

Zugangssysteme für Kraftfahrzeuge sind gegenwärtig unterteilt in sogenannte passive Zugangssysteme und sogenannte aktive Zugangssysteme. Beide umfassen einen elektronischen Schlüssel, normalerweise im Besitz einer Person, die den Zutritt zu dem Kraftfahrzeug wünscht, und einer Basisstation, die im Kraftfahrzeug angeordnet ist zur Kommunikation mit dem Schlüssel. Um einen Zugang zu dem Kraftfahrzeug zu erreichen, führen Schlüssel und Basisstation ein Sicherheitskommunikationsprotokoll aus, um zu entscheiden, ob der Zugang berechtigt ist.Motor vehicle access systems are currently divided in so-called passive access systems and so-called active access systems. Both include an electronic one Keys, usually in the possession of a person who has access to the motor vehicle and a base station, which is arranged in the motor vehicle for communication with the key. To gain access to the motor vehicle, the key and base station maintain a security communication protocol to decide if access is justified.

Passive Zugangssysteme benutzen einen Transponder als elektronischen Schlüssel. Der Transponder enthält normalerweise keine zu aktivierenden Knöpfe und kommuniziert mit der Basisstation dann, wenn er sich innerhalb einer vorgegebenen Entfernung von der Basisstation befindet. Solche Systeme sind normalerweise nicht gänzlich passiv, so daß die Basisstation zum Zwecke der Kommunikation durch eine Handlung der den Zutritt wünschenden Person aktiviert wird, wie beispielsweise durch Betätigen eines Türgriffs des Kraftfahrzeugs. Passive Zugangssysteme weisen jedoch den Nachteil auf, daß sie anfällig sind gegenüber sogenannten weitergeleiteten Attacken. Diese Attacken lassen sich durchführen, wenn der Dieb annimmt oder weiß, daß der Schlüssel sich in der Umgebung des Kraftfahrzeugs befindet. Eine elektronische Einrichtung detektiert und verstärkt die Kommunikationssignale zwischen der Basisstation und dem Schlüssel, während - falls notwendig - die Basisstation beispielsweise durch Ziehen am Türgriff aktiviert wird.Passive access systems use a transponder as an electronic one Key. The transponder normally contains no buttons to activate and communicates with the base station then if he is within a given Distance from the base station. Such systems are usually not entirely passive, so the base station for the purpose of communication through an act of the person requesting access is activated, for example by operating a door handle of the motor vehicle. Passive access systems have the disadvantage, however that they are vulnerable to so-called forwarded Attacks. These attacks can be carried out if the thief accepts or knows that the key is in the area surrounding the motor vehicle. An electronic one Device detects and amplifies the communication signals between the base station and the key while - if necessary - the base station, for example Pull on the door handle is activated.

Ein aktives Zugangssystem umfaßt einen elektronischen Schlüssel, der vom Benutzer zu aktivierende Bedienelemente umfaßt, um das Kommunikationsprotokoll auszuführen. Diese Systeme sind deshalb sicherer als passive Zugangssysteme, weil der Besitz und die Aktivierung des Schlüssels notwendig ist, um Zugang zu erhalten. Dennoch weisen diese Zugangssysteme den Nachteil auf, daß sie nicht die Benutzerfreundlichkeit des passiven Zugangssystems aufweisen.An active access system includes an electronic one Key, the control elements to be activated by the user to execute the communication protocol. This Systems are therefore more secure than passive access systems, because possession and activation of the key are necessary is to get access. Nevertheless, these access systems point The disadvantage is that it is not user friendliness of the passive access system.

Gemäß der Erfindung ist ein Zugangssystem für eine Sicherheitszone vorgesehen, das eine Basisstation in der Sicherheitszone und einen elektronischen Schlüssel zur Ausführung eines Kommunikationsprotokolls mit der Basisstation aufweist, um Zugang zur sicheren Zone zu erhalten. Das Zugangssystem zeichnet sich dadurch aus, daß der Schlüssel angepaßt ist, um mit der Basisstation zu kommunizieren, um ein passives Zugangssystem zu aktivieren oder zu deaktivieren.According to the invention is an access system for a security zone provided that a base station in the security zone and an electronic key for execution a communication protocol with the base station, to gain access to the safe zone. The access system is characterized in that the key is adapted is to communicate with the base station to a passive Activate or deactivate the access system.

Das Zugangssystem zeichnet sich dadurch aus, daß in dem Schlüssel Mittel vorgesehen sind, um mit der Basisstation zu kommunizieren, um einen eingeschränkten Betriebsmodus des Systems zu aktivieren oder zu deaktivieren. In dem beschränkten Betriebsmodus ist der Zugang zu der Sicherheitszone beschränkt.The invention relates to an access system for a security zone, which is a base station in the security zone and an electronic key for executing a communication protocol with the base station to gain access to the To maintain the security zone includes. The access system is characterized in that means are provided in the key are in order to communicate with the base station to activate a restricted operating mode of the system or disable. In the limited operating mode access to the security zone is restricted.

Bevorzugte Ausführungsbeispiele der Erfindung werden nachfolgend beispielhaft beschrieben unter Bezugnahme auf die entsprechenden Zeichnungen, wobei Figur 1 ein Blockdiagramm einer bevorzugten Ausführungsform des Zugangssystems und Figur 2 ein detaillierteres Blockdiagramm des Zugangssystems darstellen.Preferred embodiments of the invention are as follows described by way of example with reference to the corresponding drawings, wherein Figure 1 is a block diagram a preferred embodiment of the access system and figure 2 shows a more detailed block diagram of the access system represent.

Ein Zugangssystem 2 gemäß den Figuren 1 und 2 umfaßt als elektronischen Schlüssel einen Transponder 4 und eine in einem Fahrzeug 8 angeordnete Basisstation 6. Der Tansponder 4 und die Basisstation 6 sind in der Lage, miteinander über eine Funkverbindung zu kommunizieren. Der Tansponder 4 umfaßt Standardtransponderkomponenten wie eine Antenne 20, einen Empfänger 22, einen Sender 24 und einen Mikroprozessor 26 mit einem nichtflüchtigen Speicher 28. In ähnlicher Weise enthält die Basisstation 6 in dem Kraftfahrzeug 8 ebenfalls solche Standardkomponenten wie eine Antenne 30, einen Empfänger 32 und einen Mikroprozessor 34 mit einem nichtflüchtigen Speicher 36. Die Basisstation 6 ist Teil oder im Sinne einer Kommunikation verbunden mit einer elektronischen Steuereinheit 38 des Fahrzeugs 8, die elektronische Funktionen des Kraftfahrzeugs, inklusive einer Wegfahrsperrenfunktion, steuert.An access system 2 according to Figures 1 and 2 comprises as electronic key a transponder 4 and one in one Vehicle 8 arranged base station 6. The transponder 4 and the base station 6 are able to communicate with each other to communicate a radio link. The transponder 4 comprises Standard transponder components such as an antenna 20, one Receiver 22, a transmitter 24 and a microprocessor 26 with a non-volatile memory 28. Similarly also contains the base station 6 in the motor vehicle 8 such standard components as an antenna 30, a receiver 32 and a microprocessor 34 with a non-volatile Memory 36. Base station 6 is part or in the sense a communication connected to an electronic control unit 38 of the vehicle 8, the electronic functions of the motor vehicle, including an immobilizer function, controls.

Die Basisstation 6 ist in der Lage, mit dem Tansponder 4 als ein passives Zugangssystem zu kommunizieren, indem die Basisstation 6 den Transponder 4 anregt, das Sicherheitskommunikationsprotokoll zu initiieren und aktivieren. Die Basisstation 6 ist so programmiert, daß sie Konfigurationsinformationen und/oder Parameter in den Speicher 36 hinterlegt. The base station 6 is able to use the transponder 4 as a passive access system to communicate by the base station 6 excites the transponder 4, the security communication protocol to initiate and activate. The base station 6 is programmed to provide configuration information and / or parameters are stored in the memory 36.

Diese Konfigurationsinformationen und/oder Parameter können durch den Transponder 4 gesetzt werden, um den passiven Zugangsmodus und damit das passive Zugangssystem zu deaktivieren. Hierzu ist ein spezielles Initiierungssignal des aktivierten Transponders 4 notwendig, um ein Sicherheitskommunikationsprotokoll auszuführen. Die Konfigurationsinformationen und/oder Parameter können auch in der Weise gesetzt werden, daß das Zugangssystem 2 in einem Timer-Modus betrieben wird, in dem die Basisstation 6 das passive Zugangssystem für eine vorbestimmte Zeitspanne deaktiviert. Außerdem können die Konfigurationsinformationen und/oder Parameter so beeinflußt werden, daß das Zugangssystem 2 sich in einem sogenannten beschränkten Betriebsmodus befindet, in dem der Transponder 4 lediglich den Zugang zu bestimmten Zonen des Kraftfahrzeugs 8 ermöglicht und Zugang zu anderen Zonen wie beispielsweise Kofferraum oder Handschuhfach vorsieht oder unterbindet. Demgemäß weist das Zugangssystem 2 vier Betriebsarten auf, einen passiven Zugangsmodus, einen aktiven Zugangsmodus, einen Timer-Modus und einen beschränkten Betriebsmodus. Die aktuelle Betriebsart ist durch die Aktivierung und Deaktivierung der LEDs 10 und 12 angezeigt. Die Aktivierung der LED 10 zeigt den im Betrieb befindlichen passiven Zugangsmodus an, die Aktivierung der enable-LED 12 zeigt an, daß der aktive Zugangsmodus aktiv ist. Die Aktivierung der beiden LEDs zeigt den Timer-Modus an, wobei die zweimalige Aktivierung der beiden LEDs den beschränkten Betriebsmodus signalisiert. Um den Energieverbrauch zu begrenzen, bleiben die LEDs 10 und 12 nur für eine kurze Zeitspanne aktiviert. Die Betriebsart kann durch gleichzeitiges Drücken der beiden Knöpfe 14, 16 des Transponders 4 überprüft werden. Jede der Betriebsarten kann von dem Benutzer ausgewählt und konfiguriert werden, indem er den Transponder 4 zur Kommunikation mit der Basisstation 6 verwendet und die Konfigurationsinformationen und/oder Parameter einstellt. Um in den Programmiermodus zu gelangen, in dem die Betriebsarten ausgewählt und konfiguriert werden können, sind die Knöpfe 14, 16 in einer vorgegebenen Weise zu drücken, beispielsweise durch gleichzeitiges Drücken bestimmter Knöpfe oder durch Drücken in einer vorbestimmten Reihenfolge.This configuration information and / or parameters can be set by the transponder 4 to the passive access mode and thus deactivate the passive access system. For this, a special initiation signal is activated Transponders 4 necessary to use a security communication protocol to execute. The configuration information and / or parameters can also be set in such a way that the access system 2 operated in a timer mode in which the base station 6 is the passive access system deactivated for a predetermined period of time. You can also the configuration information and / or parameters so be influenced that the access system 2 is in a so-called limited operating mode in which the Transponder 4 only access to certain zones of the Motor vehicle 8 allows and access to other areas such as provides for example trunk or glove compartment or prevents. Accordingly, the access system 2 has four modes of operation on, a passive access mode, an active one Access mode, a timer mode and a limited operating mode. The current operating mode is through activation and deactivation of LEDs 10 and 12 are displayed. The activation LED 10 shows the passive one in operation Access mode on, activation of the enable LED 12 indicates that the active access mode is active. The activation of the two LEDs indicates the timer mode, the Activation of the two LEDs twice the limited operating mode signals. To limit energy consumption, LEDs 10 and 12 remain only for a short period of time activated. The operating mode can be changed by simultaneous Pressing the two buttons 14, 16 of the transponder 4 checked become. Each of the modes can be customized by the user can be selected and configured by using the transponder 4 used for communication with the base station 6 and the Set configuration information and / or parameters. Around to enter the programming mode in which the operating modes can be selected and configured are the Press buttons 14, 16 in a predetermined manner, for example by pressing certain buttons at the same time or by pressing in a predetermined order.

Der Transponder 4 umfaßt drei Standardknöpfe 14 zur Steuerung eines aktiven Zugangssystems und einen weiteren vierten Knopf 16, um das Zugangssystem 2 für eine der vier Betriebsarten zu konfigurieren. Um den passiven Zugangsmodus zu aktivieren oder zu deaktivieren um demgemäß umzuschalten zwischen passivem Zugang und aktivem Zugang, muß der vierte Knopf 16 gedrückt werden, so daß zwischen den vier Betriebsarten und in Übereinstimmung zwischen den LEDs 10 und 12 umgeschaltet wird.The transponder 4 comprises three standard buttons 14 for control an active access system and another fourth Button 16 to access system 2 for one of the four operating modes to configure. To activate the passive access mode or deactivate to switch between accordingly passive access and active access, the fourth Button 16 are pressed so that between the four modes and switched in accordance with LEDs 10 and 12 becomes.

Um die Zeit für den Timer-Modus einzustellen, muß der vierte Knopf 16 solange gedrückt werden, bis die enable-LED 10 leuchtet. Während der vierte Knopf 16 gedrückt bleibt, muß einer der anderen Knöpfe 14 in der gewünschten Weise gedrückt werden, um die Zeit für den Timer-Modus zu inkrementieren, beispielsweise um eine vorbestimmte Anzahl von Stunden mit jedem Druck. Um hierauf den Timer-Betrieb zu aktivieren, ist der vierte Knopf 16 zu drücken, um zwischen den Betriebsarten zu schalten (Toggle-Betrieb), solange bis beide LEDs 10 und 12 gleichzeitig angeschaltet sind. Im Timer-Modus arbeitet das Zugangssystem 2 wie folgt, abhängig von der Systemkonfiguration:

  • (i) der passive Zugangsmodus ist für eine vorbestimmte Zeit deaktiviert, sobald der Benutzer in den Timer-Modus wechselt;
  • (ii) der passive Zugangsmodus ist nach der vorbestimmten Zeit deaktiviert, sofern der Benutzer in den Timer-Modus wechselt; oder (iii) der passive Zugangsmodus ist nach Verstreichen einer vorbestimmten Zeitspanne, beginnend mit dem Verschließen des Kraftfahrzeugs 8, deaktiviert.
    • To set the time for the timer mode, the fourth button 16 must be pressed until the enable LED 10 lights up. While the fourth button 16 remains depressed, one of the other buttons 14 must be depressed in the desired manner to increment the timer mode time, for example, a predetermined number of hours with each press. To activate the timer mode, the fourth button 16 must be pressed to switch between the operating modes (toggle mode) until both LEDs 10 and 12 are switched on at the same time. In timer mode, access system 2 works as follows, depending on the system configuration:
  • (i) the passive access mode is deactivated for a predetermined time as soon as the user switches to the timer mode;
  • (ii) the passive access mode is deactivated after the predetermined time if the user switches to the timer mode; or (iii) the passive access mode is deactivated after a predetermined period of time has elapsed, starting with the locking of the motor vehicle 8.

    • Um den beschränkten Betriebsmodus zu aktivieren, ist der vierte Knopf 16 zu drücken, bis beide LEDs 10 und 12 zweimal aufleuchten. Die vier Knöpfe 14 und 16 werden dann benutzt, um eine persönliche Identifikationsnummer (PIN) einzugeben. Jeder Knopf 14 bis 16 steht für eine Ziffer. Bei der Eingabe der PIN leuchten die LEDs 10 und 12 dreimal auf. Dadurch wird angezeigt, daß die PIN nochmals eingegeben werden muß zur Bestätigung. Wird die korrekte PIN ein zweites Mal eingegeben, leuchten die LEDs 10 und 12 wieder dreimal auf, um die Eingabe einer korrekten PIN zu bestätigen. Eine Bestätigung der PIN ist nur dann notwendig, wenn dies durch den Benutzer ausgewählt ist und nicht von dem Hersteller des Transonders 4 vorgegeben. Der Zugang zu dem Kraftfahrzeug 8 ist dann begrenzt in der Weise, daß der Transponder 4 nicht dazu benutzt werden kann, um Zugang zu den beschränkten Bereichen zu erhalten, wie beispielsweise Kofferraum und/oder Handschuhfach des Kraftfahrzeugs 8. Die Eingabe der PIN bedeutet, daß die gleiche PIN eingegeben werden muß, um den beschränkten Betriebsmodus zu deaktivieren. Wiederum muß der vierte Knopf 16 solange gedrückt werden, bis die LEDs 10 und 12 zweimal aufleuchten. Die vier Knöpfe 14 und 16 können dann zur Eingabe des korrekten PINs benutzt werden. Wenn der korrekte PIN eingegeben wird, leuchten die LEDs 10 und 12 abwechselnd dreimal, um die Deaktivierung des beschränkten Betriebsmodus anzuzeigen. In dieser Konfiguration kann der durch die Eingabe der PIN gesicherte und in den beschränkten Betriebsmodus versetzte Transponder 4 dem Hotelpersonal oder dem Gepäckträger ausgehändigt werden. Um die Notwendigkeit der Eingabe der PIN zu vermeiden, kann der Eigentümer alternativ mit zumindest zwei Transpondern 4 versehen werden, die bis auf einen in jedem Schlüssel in dem Speicher hinterlegten schlüsselspezifischen Signatur-Code identisch sind. Wenn ein Transponder 4 zur Eingabe des beschränkten Betriebsmodus verwendet ist, empfängt die Basisstation 6 den schlüsselspezifischen Signatur-Code und speichert ihn in dem Speicher 36. Nur der Transponder 4 mit dem abgespeicherten Signatur-Code kann zur Deaktivierung des beschränkten Betriebsmodus verwendet werden. Der Eigentümer des Fahrzeugs 8 kann hierfür einen zweiten Transponder 4 für das Hotelpersonal oder den Gepäckträger vorsehen, der nicht zur Anzeige des beschränkten Betriebsmodus verwendet werden kann. Um den beschränkten Betriebsmodus zu deaktivieren, ist der Signatur-Code von der Basisstation 6 zu löschen. In einer dritten Alternative speichert die Basisstation 6 nichtflüchtig einen Mastertransponder-Signatur-Code, der ebenfalls in einem Mastertransponder hinterlegt ist, wobei der Mastertransponder dem Eigentümer zusammen mit anderen Schlüsseln ausgehändigt wird. Nur der Mastertransponder kann zur Aktivierung und Deaktivierung des Hotelbetriebsmodus verwendet werden. In dieser Ausgestaltung befindet sich der Mastertransponder immer im Besitz des Eigentümers und bedarf einer Markierung oder Farbcodierung.To activate the restricted operating mode, the fourth button 16 to press both LEDs 10 and 12 twice light up. The four buttons 14 and 16 are then used to enter a personal identification number (PIN). Each button 14 to 16 represents a number. When entering LEDs 10 and 12 of the PIN light up three times. Thereby indicates that the PIN must be entered again for confirmation. If the correct PIN is entered a second time, LEDs 10 and 12 light up three times again confirm the entry of a correct PIN. A confirmation the PIN is only necessary if this is done by the user is selected and not by the manufacturer of the transonder 4 specified. Access to the motor vehicle 8 is then limited in such a way that the transponder 4 does not do so can be used to access restricted areas to get, such as trunk and / or glove box of the motor vehicle 8. Entering the PIN means that the same PIN must be entered to access the restricted Disable operating mode. Again, the fourth button 16 pressed until the LEDs 10 and 12 light up twice. The four buttons 14 and 16 can then be used to enter the correct PIN. If the If the correct PIN is entered, LEDs 10 and 12 light up alternately three times to deactivate the restricted Operating mode. In this configuration, the secured by entering the PIN and in the restricted Operating mode offset transponder 4 to the hotel staff or are handed over to the porter. To the need Alternatively, the owner can avoid entering the PIN be provided with at least two transponders 4 which except for one stored in each key in the memory key-specific signature code are identical. If a transponder 4 for entering the restricted operating mode is used, the base station 6 receives the key-specific Signature code and stores it in memory 36. Only the transponder 4 with the stored signature code can be used to disable the limited operating mode be used. The owner of vehicle 8 can do this a second transponder 4 for the hotel staff or provide the porter who is not to display the restricted Operating mode can be used. To the limited Deactivating the operating mode is the signature code to be deleted from the base station 6. In a third alternative the base station 6 stores one permanently Master transponder signature code, which is also in a master transponder is stored, the master transponder handed over to the owner along with other keys becomes. Only the master transponder can be activated and deactivated the hotel operating mode. In this The master transponder is always in the configuration owned by the owner and requires a marker or Color coding.

    Der Transponder 4 enthält darüber hinaus eine akustische Warneinrichtung 40, die von dem Mikroprozessor 26 gesteuert wird, um ein kurzes akustisches Signal abzugeben, wenn der Transponder 4 ein Berechtigungssignal von der Basisstation 6 empfängt. Die Basisstation 6 überträgt das Berechtigungssignal, wenn sie den Zugang zu dem Kraftfahrzeug 8 zuläßt. Das Berechtigungssignal kann ebenso bei der Eingabe eines neuen Betriebsmodus übertragen werden. Sofern sich der Besitzer des Tansponders 4 innerhalb der Reichweite des Kraftfahrzeugs 8 befindet, wird der Besitzer auf den aktivierten Zugang zu dem Kraftfahrzeug 8 aufmerksam gemacht, entweder eingeleitet durch den Transponder 4 des Eigentümers oder einer anderen Partei, beispielsweise einer unberechtigten Person. The transponder 4 also contains an acoustic Warning device 40 controlled by the microprocessor 26 to give a short beep when the Transponder 4 an authorization signal from the base station 6 receives. The base station 6 transmits the authorization signal, if it allows access to the motor vehicle 8. The authorization signal can also be entered when entering a new operating mode are transmitted. Unless the owner of the transponder 4 within the range of the motor vehicle 8 is located, the owner is activated on the Access to the motor vehicle 8, either initiated by the owner's transponder 4 or one other party, for example an unauthorized person.

    Zur Unterstützung des Benutzers kann der Transponder 4 mit einer LCD-Anzeige versehen sein anstelle der LEDs 10 und 12. Die LCD-Anzeige wird gesteuert durch den Mikroprozessor 26. Die LCD-Anzeige ist in dem Transponder 4 integriert und kann aktiviert werden, um den Benutzern Meldungen anzuzeigen, so daß sie leicht zwischen den vier Betriebsarten wechseln können. Die LCD-Anzeige kann alternativ oder zusätzlich auch im Kraftfahrzeug 8 angeordnet sein und mit der Basisstation 6 verbunden werden, um die gleiche Anzeige wie die des Tansponders 4 zu erhalten. Die Knöpfe auf dem Transponder 4 können benutzt werden oder es sind zusätzliche Steuerknöpfe in dem Kraftfahrzeug 8 hinzuzufügen. In einer alternativen Ausgestaltung sind weder ein zusätzlicher Knopf 16 noch eine zusätzliche LED notwendig. Die existierende Knöpfe 14 und die existierende LED 10 des Transponders 4 können für mehrere Funktionen benutzt werden. Beispielsweise können zwei der existierenden Knöpfe 14 gleichzeitig gedrückt werden, um zwischen den vier Betriebsarten umzuschalten. Der Timer kann auch gesetzt werden, indem zwei der Knöpfe 14 gleichzeitig für eine vorbestimmte Zeit gedrückt werden, und während die LED in einer bestimmten Weise blinkt, kann einer der Knöpfe 14 dazu verwendet werden, um die Verzögerungszeit einzustellen. Die Betriebsart, in der sich das System 2 befindet, kann über die Blinkfrequenz der existierenden LED 10 angezeigt werden.To support the user, the transponder 4 can be used be provided with an LCD display instead of LEDs 10 and 12. The LCD display is controlled by the microprocessor 26. The LCD display is integrated in the transponder 4 and can be activated to display messages to users, so that they can easily switch between the four modes. The LCD display can alternatively or additionally also in the Motor vehicle 8 can be arranged and with base station 6 connected to the same display as that of the Get Tansponders 4. The buttons on the transponder 4 can be used or there are additional control buttons add in the motor vehicle 8. In an alternative Design are neither an additional button 16 nor one additional LED necessary. Existing buttons 14 and the existing LED 10 of the transponder 4 can be used for several Functions are used. For example, two of the existing buttons 14 are pressed simultaneously to switch between the four operating modes. The timer can can also be set by two of the buttons 14 simultaneously pressed for a predetermined time and while the LED flashes in a certain way, one of the buttons 14 can be used to set the delay time. The operating mode in which system 2 is located can be displayed via the flashing frequency of the existing LED 10 become.

    Das Zugangssystem 2 ist besonders vorteilhaft, weil es dem Benutzer mit all den Vorzügen eines passiven Zugangssystems ausstattet, jedoch die Sicherheit des Systems erhöht - sofern gewünscht -. Das System ist nicht anfällig gegen sogenannte weitergeleitete Attacken.Schläft der autorisierte Benutzer beispielsweise in einem Motel, benachbart zu dem Kraftfahrzeug 8, so kann der passive Zugangsmodus unverzüglich deaktiviert werden oder für eine vorbestimmte Zeitspanne in den Timer-Modus gebracht werden. Das Zugangssystem 2 kann in einen beschränkten Zugangsmodus versetzt werden. Der Transponder 4 gibt ein aktustisches Signal ab, wenn er sich in Reichweite befindet und das Zugangssystem 2 unautorisierten Zugang vorsieht. Das Zugangssystem 2 weist die Vorzüge eines passiven Zugangssystem auf und die Sicherheit eines aktiven Zugangssystems, wobei dies ohne doppelte Auslegung der Standardkomponenten möglich ist, außer vielleicht das Versehen eines Schlüssels mit einem zusätzlichen Steuerknopf, visueller oder akustischer Anzeige.The access system 2 is particularly advantageous because it User with all the advantages of a passive access system equipment, but increases the security of the system - if desired -.
