Abstract

Motor vehicle keyless entry system has a first portable transceiver (14, 16) and a second onboard transceiver (18). The range of the mobile transceiver is greater than that of the onboard transceiver. Also the transceiver system is configured so that the commands that the mobile transceiver can issue to the second transceiver are divided into two sets (A, B). With one set only able to be carried out within a range that is closer to the vehicle than the other set. The analysis unit on the second onboard transceiver determines which category a command falls into and then executes it in a range dependent manner.

Bevor eine jeweilige Funktion ausgeführt werden kann, wird der von der Chipkarte übermittelte Identifikationscode geprüft.There are already chip card systems for keyless entry (keyless entry) for which the key is used to replace the Chip card, for example, the doors and trunk of the person concerned Motor vehicle opened and its engine can be started. there are integrated between a transmitter in the motor vehicle as well as a receiver comprising transceiver and the chip card transmit and Response signals changed. Before performing any function can be, the identification code transmitted by the chip card checked.

Bei einem aus der EP-A-0 965 710 bekannten Kraftfahrzeugbedienungssystem werden zur Schonung der Batterie von dem im Fahrzeug installierten Steuersystem zunächst Überwachungssignale geringer Energie ausgesandt, um einem weitreichenden Bereich auf die Präsenz einer die Benutzeridentifikation dienenden tragbaren Einrichtung hin zu überwachen. Erst dann, wenn auf diese Weise eine tragbare Einheit erfaßt wurde, wird auf eine die Batterie stärker belastende Überwachung einer Vielzahl unterschiedlich positionierter Nahbereiche umgeschaltet. Dabei geht die jeweilige Kommunikation sowohl für den weitreichenden Bereich als auch für die Nahbereiche jeweils von dem im Fahrzeug installierten Steuersystem aus.In a motor vehicle operating system known from EP-A-0 965 710 are used to protect the battery from the one installed in the vehicle Control system first sent out monitoring signals of low energy, to a wide area on the presence of a user identification serving portable device to monitor. Only when a portable unit has been detected in this way, is on monitoring a large number of the batteries, which is more demanding on the battery positioned close ranges switched. The goes respective communication both for the far-reaching area as well for the close-up areas in each case by the control system installed in the vehicle out.

Ein Nachteil der bekannten Systeme besteht darin, daß alle nach einer Erfassung der tragbaren Einrichtung auszuführenden Funktionen in der Regel bei sich innerhalb einer bestimmten, üblicherweise kleineren Reichweite befindender Einrichtung ausgeführt werden.A disadvantage of the known systems is that all after one Capture the portable device functions to be performed in the Usually within a certain, usually smaller range located facility to be executed.

Ziel der Erfindung ist es, ein Funk-Fernbedienungssystem der eingangs genannten Art zu schaffen, das auf einfache und entsprechend kostengünstige Weise insbesondere auch eine reichweitenabhängige Ausführung unterschiedlicher Funktionen gestattet.The aim of the invention is to provide a radio remote control system at the beginning to create the type mentioned in a simple and correspondingly inexpensive In particular, a range-dependent version different functions allowed.

Zur Lösung dieser Aufgabe wird erfindungsgemäß ein Funk-Fernbedienungssystem insbesondere für Kraftfahrzeuge vorgeschlagen, mit einem einer tragbaren Bedienungseinrichtung zugeordneten ersten Transceiver zur Kommunikation mit einem insbesondere einem Kraftfahrzeug zugeordneten zweiten Transceiver über eine bidirektionale Funkstrecke, deren Reichweite für vom ersten Transceiver ausgesandte Befehlssignale größer ist als für auf den Empfang solcher Befehlssignale hin vom zweiten Transceiver ausgesandte Rückfragesignale, wobei die vom zweiten Transceiver empfangenen Befehle in einer zugeordneten Steuer- und/oder Auswerteeinheit daraufhin ausgewertet werden, ob sie einer ersten Kategorie von Befehlen, die auch noch bei einem der größeren Reichweite entsprechenden größeren gegenseitigen Abstand der beiden Transceiver ausgeführt werden dürfen, oder einer zweiten Kategorie von Befehlen zuzuordnen sind, die nur bei sich innerhalb einer kleineren Reichweite befindender Bedienungseinrichtung ausgeführt werden dürfen, ein vom zweiten Transceiver empfangener Befehl, der der ersten Befehlskategorie zugeordnet wurde, über die Steuer- und/oder Auswerteeinheit direkt ausgeführt wird, vom zweiten Transceiver jeweils nur dann ein Rückfragesignal ausgesandt . wird, wenn der jeweilige empfangene Befehl einer zweiten Befehlskategorie zugeordnet wurde, und der erste Transceiver auf den Empfang einer Rückfrage hin ein Bestätigungssignal aussendet, auf dessen Empfang durch den zweiten Transceiver hin der betreffende, einer zweiten Befehlskategorie zugeordnete Befehl ausgeführt wird.According to the invention, a radio remote control system is used to achieve this object especially proposed for motor vehicles with a a first transceiver assigned to a portable operating device for communication with a motor vehicle in particular second transceiver over a bidirectional radio link whose Range for command signals transmitted by the first transceiver is greater is as for receiving such command signals from the second transceiver transmitted inquiry signals, the signals from the second transceiver received commands in an assigned control and / or evaluation unit thereupon be evaluated whether they belong to a first category of Orders that also correspond to a larger range distance between the two transceivers may be assigned to a second category of commands are those that are only within a smaller range Operating device may be carried out, one from the second transceiver received command assigned to the first command category was executed directly via the control and / or evaluation unit, The second transceiver then only sends out a query signal. if the respective received command of a second command category has been assigned and the first transceiver to receive one Sends a confirmation signal upon receipt, upon receipt through the second transceiver, the relevant, a second command category assigned command is executed.

Aufgrund dieser Ausbildung ist auf besonders einfache und entsprechend kostengünstige Weise eine reichweitenabhängige Ausführung unterschiedlicher Funktionen möglich. Von Vorteil ist auch, daß zur Realisierung des erfindungsgemäßen Funk-Fernbedienungssystems zur Erfüllung anderer Anforderungen vorgesehene Komponenten bereits existierender Systeme verwendet werden können. Es ergibt sich somit mit minimalem Aufwand sowie bei minimalem Platzbedarf ein insgesamt höheres Leistungsvermögen.Because of this training is particularly simple and appropriate cost-effective way a range-dependent execution of different Functions possible. It is also advantageous that to implement the Radio remote control system according to the invention to meet others Components of existing systems that are intended to meet the requirements can be used. It thus results with minimal effort as well as a higher overall performance with minimal space requirements.

In bestimmten Fällen kann es von Vorteil sein, wenn mehrere, unterschiedlichen kleineren Reichweiten zugeordnete zweite Befehlskategorien vorgesehen sind und die Reichweiten der Funkstrecke für die vom zweiten Transceiver auf den Empfang entsprechender Befehle hin ausgesandten Rückfragen je nachdem, welcher dieser zweiten Befehlskategorien der jeweils empfangene Befehl zuzuordnen ist, entsprechend unterschiedlich gewählt sind.
An den zweiten Transceiver sind vorzugsweise verschiedene Antennen anschließbar. Dabei können für die größere Reichweite und eine jeweilige kleinere Reichweite der Funkstrecke unterschiedliche Antennen vorgesehen sein. In certain cases it may be advantageous if several second command categories assigned to different, smaller ranges are provided and the ranges of the radio link for the queries sent by the second transceiver upon receipt of corresponding commands, depending on which of these second command categories to assign the command received in each case is selected accordingly.
Various antennas can preferably be connected to the second transceiver. Different antennas can be provided for the larger range and a respective smaller range of the radio link.

The invention is explained below using an exemplary embodiment with reference to the drawing; in this show:

further details of the radio remote control system.

Die Figuren 1 und 2 zeigen in rein schematischer Darstellung ein Funk-Fernbedienungssystem 10 für ein Kraftfahrzeug 12.Figures 1 and 2 show a purely schematic representation of a radio remote control system 10 for a motor vehicle 12.

Dieses Funk-Fernbedienungssystem 10 umfaßt einen einer tragbaren Bedienungseinrichtung 14 zugeordneten ersten Transceiver 16 sowie einen im Kraftfahrzeug 12 installierten zweiten Transceiver 18. Die Transceiver 16, 18 enthalten jeweils einen Sender und einen Empfänger. Die Kommunikation zwischen diesen beiden Transceivern 16, 18 erfolgt über eine bidirektionale Funkstrecke 20.This radio remote control system 10 includes a portable one Operating device 14 assigned first transceiver 16 and a second transceiver 18 installed in the motor vehicle 12. The transceivers 16, 18 each contain a transmitter and a receiver. The Communication between these two transceivers 16, 18 takes place via a bidirectional radio link 20.

Dabei ist die Reichweite R1 dieser bidirektionalen Funkstrecke 20 für vom ersten Transceiver 16 ausgesandte Befehlssignale 22 größer als die Reichweite R2 für auf den Empfang solcher Befehlssignale 22 hin vom zweiten Transceiver 18 ausgesandte Rückfragesignale 24.
Es existiert ein Satz von Befehlen, die in zumindest zwei Befehls- bzw. Funktionskategorien A und B unterteilt werden können. Die Unterteilung erfolgt nach dem Kriterium, aus welcher Entfernung ein jeweiliger Befehl 22 (z.B. Ansteuern der elektrischen Fensterheber, Ansteuern der Zentralverriegelung, Ansteuern des Lenkradschlosses, usw.) ausgeführt werden darf. Die entsprechenden Befehlssätze können beispielsweise in dem ersten Transceiver 16 gespeichert sein und beispielsweise über ein Bedienfeld 26 dieses Transceivers 16 abgerufen werden. Dabei können in dem Bedienfeld 26 beispielsweise entsprechende Bedienknöpfe 28 oder dergleichen vorgesehen sein.The range R1 of this bidirectional radio link 20 for command signals 22 transmitted by the first transceiver 16 is greater than the range R2 for query signals 24 transmitted by the second transceiver 18 upon receipt of such command signals 22.
There is a set of commands that can be divided into at least two command and function categories A and B. The subdivision is based on the criterion from which distance a respective command 22 (for example actuation of the electric window lifters, actuation of the central locking system, actuation of the steering wheel lock, etc.) may be carried out. The corresponding command sets can, for example, be stored in the first transceiver 16 and can be called up, for example, via a control panel 26 of this transceiver 16. Corresponding control buttons 28 or the like can be provided in the control panel 26, for example.

Die vom zweiten Transceiver 18 empfangenen Befehle 22 werden in einer diesem zweiten Transceiver 18 zugeordneten, im Fahrzeug 12 installierten Steuer- und/oder Auswerteeinheit 30 daraufhin ausgewertet, ob sie beispielsweise einer ersten Kategorie A (z.B. Fahrzeugtür verriegeln) von Befehlen 22, die auch noch bei einem der größeren Reichweite R1 entsprechenden größeren gegenseitigen Abstand a1 der beiden Transceiver 16, 18 ausgeführt werden dürfen, oder beispielsweise einer zweiten Kategorie B von Befehlen 22 zuzuordnen sind, die nur bei sich innerhalb einer kleineren Reichweite R2 befindender Bedienungseinrichtung 14 ausgeführt werden dürfen. Der gegenseitige Abstand der beiden Transceiver 16, 18 muß im zweiten Fall also entsprechend kleiner sein.The commands 22 received by the second transceiver 18 are in one assigned to this second transceiver 18 and installed in the vehicle 12 Control and / or evaluation unit 30 then evaluates whether, for example a first category A (e.g. locking the vehicle door) from Commands 22, which also correspond to one of the larger range R1 greater mutual distance a1 of the two transceivers 16, 18 may be executed, or for example a second category B of instructions 22 are to be assigned, which are only within one Operating range 14 located within a smaller range R2 may be. The mutual distance between the two transceivers 16, 18 must therefore be correspondingly smaller in the second case.

Wird nun vom zweiten Transceiver 18 ein Befehl 22 empfangen, der durch die Steuer- oder Auswerteeinheit 30 der ersten Befehlskategorie A zugeordnet werden kann, so wird dieser Befehl 22 über die Steuer- und/oder Auswerteeinheit 30 direkt ausgeführt. Vom zweiten Transceiver 18 wird jeweils nur dann ein Rückfragesignal 24 ausgesandt, wenn der jeweilige empfangene Befehl 22 von der Steuer- und/oder Auswerteeinheit 30 einer zweiten Befehlskategorie B zugeordnet wurde.A command 22 is now received by the second transceiver 18, which by the control or evaluation unit 30 assigned to the first command category A. can be, this command 22 via the control and / or Evaluation unit 30 executed directly. The second transceiver 18 a query signal 24 is only sent if the respective received command 22 from the control and / or evaluation unit 30 one second command category B was assigned.

Der erste Transceiver 16 sendet auf den Empfang einer Rückfrage 24 hin ein Bestätigungssignal aus, auf dessen Empfang durch den zweiten Transceiver 18 hin der betreffende, einer zweiten Befehlskategorie B zugeordnete Befehl 22 ausgeführt wird. Falls das Rückfragesignal 24 vom ersten Transceiver 16 nicht empfangen wird, liegt dieser außerhalb der für Befehle 22 der Befehlskategorie B geltenden kleineren Reichweite R2. Der betreffende Befehl wird in diesem Fall nicht ausgeführt. The first transceiver 16 transmits upon receipt of an inquiry 24 an acknowledgment signal, upon receipt by the second Transceiver 18 towards the relevant one assigned to a second command category B. Command 22 is executed. If the inquiry signal 24 from first transceiver 16 is not received, this is outside of the for Commands 22 of command category B apply smaller range R2. The the relevant command is not executed in this case.

An den zweiten Transceiver 18 sind vorzugsweise verschiedene Antennen 32, 34 anschließbar. So können z.B. die an verschiedenen Stellen des Kraftfahrzeugs wie z.B. an den seitlichen Türen sowie am Kofferraumdeckel positionierten Antennen 32 dem durch die kleinere Reichweite R2 definierten Bereich B2 und die Antenne 34 dem durch die größere Reichweite R1 definierten Bereich B1 zugeordnet sein. Für die größere Reichweite R1 und eine jeweilige kleinere Reichweite R2 der Funkstrecke 20 können somit unterschiedliche Antennen 34, 32 vorgesehen sein.Different antennas are preferably on the second transceiver 18 32, 34 can be connected. For example, at various points in the Motor vehicle such as on the side doors and on the trunk lid positioned antennas 32 due to the smaller range R2 defined area B2 and the antenna 34 by the greater range R1 defined area B1 assigned. For the greater range R1 and a respective smaller range R2 of the radio link 20 Different antennas 34, 32 can thus be provided.

Während im vorliegenden Fall mehrere für die kleinere Reichweite R2 der Funkstrecke 20 bestimmte Antennen 32 und nur eine für die größere Reichweite R1 der Funkstrecke 20 bestimmte Antenne 34 vorgesehen ist, ist es insbesondere auch möglich, mehrere Antennen für eine jeweilige größere Reichweite R1 einzusetzen.While in the present case several for the smaller range R2 the Radio link 20 certain antennas 32 and only one for the larger one Range R1 of the radio link 20 specific antenna 34 is provided, it is in particular also possible to use several antennas for each use longer range R1.

Grundsätzlich können auch mehrere, unterschiedlichen kleineren Reichweiten R2 zugeordnete zweite Befehlskategorien B vorgesehen sein. In diesem Fall können die kleineren Reichweiten R2 der Funkstrecke 20 für die vom zweiten Transceiver 18 auf den Empfang entsprechender Befehle 22, B hin ausgesandten Rückfragen 24 je nachdem, welcher dieser zweiten Befehlskategorien B der jeweils empfangene Befehl zuzuordnen ist, entsprechend unterschiedlich gewählt sein.In principle, several, different, smaller ranges can also be used Second command categories B assigned to R2 can be provided. In In this case, the smaller ranges R2 of the radio link 20 for those from the second transceiver 18 upon receipt of corresponding commands 22, B queries sent out depending on which of these second Command categories B the assigned command is assigned, be chosen differently accordingly.

Auch die tragbare Bedienungseinrichtung 14 kann mit einer Steuerund/oder Auswerteeinheit, einer oder mehreren Antennen und/oder dergleichen versehen sein.The portable operating device 14 can also be operated with a control and / or Evaluation unit, one or more antennas and / or the like.

Die jeweilige Form und/oder Größe bzw. Reichweite R1, R2 der betreffenden Empfangs- und/oder Sendebereiche B1, B2 kann zumindest teilweise durch die Art der Antennen 32, 34 und/oder durch Parameter wie insbesondere die Sendeleistung und/oder dergleichen bestimmt sein.The respective shape and / or size or range R1, R2 of the relevant Reception and / or transmission areas B1, B2 can at least partially by the type of antennas 32, 34 and / or by parameters such as in particular the transmission power and / or the like can be determined.

Wie anhand der Figur 1 zu erkennen ist, kann die Frequenz f1 der vom ersten Transceiver 16 ausgesandten Signale 22 von der Frequenz f2 der vom zweiten Transceiver 18 ausgesandten Signale 24 verschieden sein.As can be seen from FIG. 1, the frequency f1 can be that of first transceiver 16 signals 22 emitted by the frequency f2 signals 24 emitted by the second transceiver 18 may be different.

Das Funk-Fernbedienungssytem 10 kann beispielsweise Teil eines schlüssellosen Zugangssystems sein. Dabei kann die tragbare Bedienungseinrichtung 14 insbesondere auch der Benutzeridentifikation dienende Mittel umfassen. The radio remote control system 10 can, for example, be part of a keyless one Access system. The portable control device 14 in particular also means for user identification include.
