Abstract

Safety system for motor vehicles, comprising a portable transmitter (1) for a coded signal which is radiotransmitted and a receiver (4) arranged inside the motor vehicle, which modifies the state of the theft-protection devices when it receives the appropriate coded signal. In this system, the coded signal includes an additional part for setting the operating elements of the motor vehicle according to the user. The transmitter (1) is specially designed so that the theft-protection devices no longer have to be separately unlocked and the user no longer needs to set said elements individually.

Description

Sicherheitseinrichtung für Kraftfahrzeuge.Safety device for motor vehicles.
Die Erfindung bezieht sich auf eine Sicherheitseinrich¬ tung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a safety device according to the preamble of patent claim 1.
Derartige Sicherheitseinrichtungen sind in verschiedener Form bekannt. Es ergibt sich aus der DE-OS 36 27 194 ein tragbarer Hochfrequenzsender für schlüssellose Zugangs¬ systeme, der selbst als Chipkarte ausgebildet ist. Das Zusammenspiel zwischen Sender und Empfänger kann auf unterschiedliche Weise gestaltet sein. So ist es bei¬ spielsweise möglich, den Sender selbst mit einem Betä¬ tigungsglied zu versehen, durch das der Sender zur Abgabe des Codesignals veranlaßt wird. Daneben aber sind Sicherheitseinrichtungen der eingangs genannten Art bekannt, bei denen durch den Empfänger der Sender zur Abgabe des Codesignals veranlaßt wird. Hierzu ist auf die DE-OS 35 36 377 zu verweisen, bei der der Empfänger seinerseits ein Fragesignal an den tragbaren Sender dann aussendet, wenn eine Türklappe oder dgl. betätigt wird.Such safety devices are known in various forms. DE-OS 36 27 194 results in a portable high-frequency transmitter for keyless access systems, which is itself designed as a chip card. The interaction between transmitter and receiver can be designed in different ways. For example, it is possible to provide the transmitter itself with an actuating element by which the transmitter is caused to emit the code signal. In addition, however, security devices of the type mentioned at the outset are known in which the receiver causes the transmitter to emit the code signal. For this purpose, reference is made to DE-OS 35 36 377, in which the receiver in turn sends a question signal to the portable transmitter when a door flap or the like is actuated.
Neben Sicherheitseinrichtungen der eingangs genannten Art ist es ferner bekannt, innerhalb des Kraftfahrzeugs eine sog. Memory-Einrichtung vorzusehen, die benutzer¬ individuelle Einstellungen von Bedien- und Benutzungs¬ elementen des Kraftfahrzeugs steuert. Hierzu gehört beispielsweise die Einstellung des Fahrersitzes hinsichtlich seiner axialen Stellung, die Neigung der Rückenlehne und die Höhenlage der Kopfstütze. Ferner gehören hierzu auch Einstellungen der Rückblickspiegel, des Lenkrades, der Pedalerie und auch der Heiz- und Klimaanlage, der maximal zulässigen Geschwindigkeit sowie weiterer Komforteinrichtungen, wie beispielsweise der Stoßdämpfer. Mit Hilfe der Memory-Einrichtung wird für den jeweiligen Fahrzeugbenutzer die für ihn passende Einstellung dieser Elemente selbsttätig vorgenommen. Die Memory-Einrichtung ihrerseits wiederum wird gesteuert durch den Benutzer. Sie kann beispielsweise verschiedene Druck astenschalter besitzen, die eine Einstellung der genannten Elemente auf drei verschiedene Arten für den Fahrzeugbenutzer 1, 2 bzw. 3 ermöglichen.In addition to safety devices of the type mentioned at the outset, it is also known to provide what is known as a memory device within the motor vehicle, which controls user-specific settings of operating and use elements of the motor vehicle. This includes setting the driver's seat, for example in terms of its axial position, the inclination of the backrest and the height of the headrest. This also includes settings for the rearview mirror, the steering wheel, the pedals and also the heating and air conditioning system, the maximum permissible speed and other comfort features such as the shock absorber. With the help of the memory device, the appropriate setting of these elements is carried out automatically for the respective vehicle user. The memory device in turn is controlled by the user. For example, it can have different push-button switches that enable the above-mentioned elements to be set in three different ways for vehicle users 1, 2 and 3.
Zwar bietet eine Memory-Einrichtung einen erheblichen Komfortgewinn, doch besitzt sie ihrerseits den Nachteil, daß es in der Regel dem Fahrzeugbenutzer selbst über¬ lassen bleibt, die "richtige" Auswahl zu treffen. Häufig kann es vorkommen, daß eine falsche Auswahl nicht oder nur zu spät erkannt wird mit der Folge, daß der eigent¬ liche Vorteil einer Memory-Einrichtung ins Gegenteil verkehrt wird.Although a memory device offers a considerable gain in comfort, it has the disadvantage that it is usually left to the vehicle user himself to make the "right" selection. It can often happen that an incorrect selection is not recognized or is recognized only too late, with the result that the actual advantage of a memory device is reversed.
Der Erfindung liegt die Aufgabe zugrunde, eine Sicher¬ heitseinrichtung der eingangs genannten Art zu schaffen, die mit einem Höchstmaß an Komfort sowohl die Steuerung der Diebstahlschutzeinrichtungen als auch weiterer benutzerindividuell einstellbarer Elemente ermöglicht.The invention is based on the object of providing a security device of the type mentioned at the outset which, with maximum convenience, enables both the control of the anti-theft devices and further elements which can be set individually for the user.
Die Erfindung löst diese Aufgabe durch die kennzeich¬ nenden Merkmale des Patentanspruchs 1.The invention solves this problem by the characterizing features of claim 1.
Wesentlich für die Erfindung ist, daß das Codesignal aus zwei Teilen besteht. Ein Teil ist für jeden Benutzer gleich und dient dazu, die Legitimation des Fahrzeugbe- nutzers für das jeweilige Kraftfahrzeug festzustellen. Wird vom Fährzeugbenutzer das richtige Codesignal hinsichtlich dieses Teiles ausgesandt, so werden die Diebstahlschutzeinrichtungen in den gewünschten Zustand versetzt. Dabei kann es sich beispielsweise um eine zentrale Ver- und Entriegelungsanlage sowie um ein Zündschloßsystem handeln.It is essential for the invention that the code signal consists of two parts. One part is the same for every user and is used to legitimize the vehicle determine user for the respective motor vehicle. If the vehicle user sends out the correct code signal with regard to this part, the anti-theft devices are set to the desired state. This can be, for example, a central locking and unlocking system and an ignition lock system.
Der weitere Anteil des Codesignals ist dem jeweiligen Fahrzeugbenutzer individuell zugeordnet und veranlaßt über eine entsprechende Auswertungseinrichtung, die dem Empfänger nachgeschaltet ist, die benutzerindividuelle Einstellung der genannten Elemente. Damit ist eine deutliche Komfortverbesserung verbunden, da es für den Fahrzeugbenutzer nicht mehr erforderlich ist, die Diebstahlschutzeinrichtungen und die benutzerindividuell einstellbaren Einrichtungen unabhängig voneinander und durch in der Regel zwei separate Bedienungsvorgänge zu steuern. Vielmehr wird im Rahmen der Überprüfung des Fahrzeugbenutzers hinsichtlich seiner Berechtigung bei positivem Ergebnis dieser Überprüfung gleichzeitig auch die individuelle Einstellung der genannten Elemente vorgenommen. Dies kann wie für die Steuerung der Diebstahlschutzeinrichtungen ohne separate Steuerung des Senders in der aus der DE-OS 35 36 377 bekannten Weise selbsttätig beim Versuch des Fahrzeugbenutzers erfolgen, das Kraftfahrzeug mit Hilfe der Türklappe zu öffnen.The further portion of the code signal is individually assigned to the respective vehicle user and, via a corresponding evaluation device which is connected downstream of the receiver, initiates the user-specific setting of the elements mentioned. This is associated with a significant improvement in comfort, since it is no longer necessary for the vehicle user to control the theft protection devices and the user-individually adjustable devices independently of one another and, as a rule, by means of two separate operating processes. Rather, as part of the verification of the vehicle user with regard to his authorization, if the result of this verification is positive, the individual setting of the elements mentioned is also carried out at the same time. This can be done automatically for the control of the theft protection devices without separate control of the transmitter in the manner known from DE-OS 35 36 377 when the vehicle user tries to open the motor vehicle with the help of the door flap.
Es ist ohne weiteres erkennbar, daß bei der erfindungs¬ gemäßen Sicherheitseinrichtung eine Begrenzung der verschiedenen Verstellmöglichkeiten, wie sie beispiels- weise bei einer Memor -Einrichtung mit drei Drucktasten¬ schaltern gegeben ist, nicht besteht. Dies ist unabhängig davon, wie der zusätzliche Anteil des Codesignals beschaffen ist. Es kann sich dabei lediglich um eine Codierung für den jeweiligen Fahrzeugbenutzer handeln. Mit Hilfe einer im Kraftfahrzeug vorgesehenenIt can easily be seen that the safety device according to the invention does not have a limitation of the various adjustment options, such as is given, for example, in the case of a memory device with three push-button switches. This is irrespective of how the additional portion of the code signal is designed. It can only be a coding for the respective vehicle user act. With the help of a provided in the motor vehicle
Memory-Einrichtung wird dann zu dieser Codierung die jeweilige Einstellung der genannten Elemente vorgenommen. Es kann sich beim zusätzlichen Anteil aber auch um eine Codierung der verschiedenenThe memory device is then made for this coding, the respective setting of the elements mentioned. The additional portion can also be a coding of the different ones
Eins ellmδglichkeiten selbst handeln. Der zusätzlicheOne way to act yourself. The additional
Anteil des Codesignals setzt sich somit zusammen aus verschiedenen Teilen, die jeweils einem der Elemente zugeordnet sind und die dessen Einstellung bestimmen. Damit kann eine Memory-Einrichtung im Kraftfahrzeug entfallen. Es ist dann lediglich erforderlich, die im zusätzlichen Anteil enthaltenen Vorgaben für diePart of the code signal is thus composed of different parts, each of which is assigned to one of the elements and which determine its setting. A memory device in the motor vehicle can thus be dispensed with. It is then only necessary to specify the requirements contained in the additional part for the
Einstellung der Elemente entsprechend umzusetzen.Implement the setting of the elements accordingly.
Weiter ist die Wirkungsweise der erfindungsgemäßen Sicherheitseinrichtung auch unabhängig davon, in welcher Weise der zusätzliche Anteil des Codesignals ausgesandt wird. Es kann sich dabei sowohl um einen zusätzlichen Anteil handeln, der unmittelbar im Anschluß an den ersten, für die Identifizierung des Fahrzeugbenutzers charakteristischen Anteil ausgesandt wird. Es wird in diesem Fall ein einheitliches Codesignal vom Sender erzeugt. Alternativ dazu kann der zusätzliche Anteil auch zeitlich verzögert ausgesandt werden. Dies kann beispielsweise in Form eines Frage-/Antwort-Dialogs erfolgen, bei dem zunächst der erste Anteil vom Sender ausgesandt wird und bei erfolgreichem Empfang aufgrund eines vom Empfänger ausgesandten Empfangsbestätigungs¬ signals der zweite Anteil vom Sender ausgesandt wird.Furthermore, the mode of operation of the security device according to the invention is also independent of the manner in which the additional portion of the code signal is transmitted. It can be both an additional portion that is sent out immediately after the first portion that is characteristic of the identification of the vehicle user. In this case, the transmitter generates a uniform code signal. Alternatively, the additional portion can also be sent with a time delay. This can take place, for example, in the form of a question / answer dialog, in which the first part is first sent out by the transmitter and, if reception is successful, the second part is sent out by the transmitter on the basis of an acknowledgment signal sent by the receiver.
Eine Weiterbildung der Erfindung beschäftigt sich mit der Handhabung einer derartigen Sicherheitseinrichtung. Es kann sich beim Sender um eine Einrichtung handeln, die eine benutzerindividuelle Kennung, beispielsweise in Form einer Aufschrift oder unterscheidungskräftigen Formgestaltung des Sender-Gehäuses handelt. Alternativ dazu ist es besonders vorteilhaft, dem zusätzlichen Anteil des Codesignals ein separates mechanisches Teil zuzuordnen, das Teil des Senders ist und gegenüber diesem demontierbar ist. Auf diese Weise ist es möglich, mit einem Grundmodul für den Sender durch Hinzufügen eines benutzerindividuellen mechanischen Teils den Sender zu komplettieren. Somit ist zur benutzerindivi¬ duellen Generierung des Senders lediglich die Hinzufü¬ gung des jeweiligen mechanischen Teiles erforderlich.A further development of the invention deals with the handling of such a safety device. The transmitter can be a device which is a user-specific identifier, for example in the form of an inscription or a distinctive design of the transmitter housing. Alternatively for this purpose, it is particularly advantageous to assign a separate mechanical part to the additional portion of the code signal, which part is part of the transmitter and can be removed from it. In this way it is possible to complete the transmitter with a basic module for the transmitter by adding a user-specific mechanical part. Thus, for the user-specific generation of the transmitter, only the addition of the respective mechanical part is required.
Das mechanische Teil seinerseits kann auf unterschied¬ liche Weise gestaltet sein. Es kann beispielsweise eine magnetische Codierung besitzen, die vom Fahrzeugbenutzer selbst durch Einstellen lageveränderlicher Magnetkörper erzeugt wird. Demgegenüber ergibt sich eine deutliche Verbesserung, wenn das demontierbare Teil einen elek¬ tronischen Speicher enthält, der entsprechend dem zusätzlichen Anteil des Codesignals belegt ist. Auf diese Weise wird es möglich, den zusätzlichen Anteil des Codesignals so zu gestalten, daß er aus einzelnen Teilen besteht, von denen jeder für sich die Einstellung eines Kraftfahrzeug-Bedien- bzw. Benutzungselements ermög¬ licht. Darüber hinaus ist ein derartiger Speicher mechanisch unempfindlich und schließt damit die Gefahr von Fehleinstellungen der genannten Elemente aus.The mechanical part in turn can be designed in different ways. For example, it can have a magnetic coding that is generated by the vehicle user himself by adjusting magnet bodies that can be changed in position. In contrast, there is a significant improvement if the removable part contains an electronic memory which is occupied in accordance with the additional portion of the code signal. In this way it becomes possible to design the additional portion of the code signal so that it consists of individual parts, each of which enables the setting of a motor vehicle operating or use element. In addition, such a memory is mechanically insensitive and thus eliminates the risk of incorrect settings of the elements mentioned.
Eine besonders vorteilhafte Gestaltung des elektroni¬ schen Speichers ergibt sich, wenn dieser in einer Chipkarte enthalten ist. Chipkarten gewinnen zunehmend an Bedeutung und dienen als Zahlungs- bzw. Abrechnungs¬ mittel. Im Rahmen der Erfindung können sie neben der üblichen Funktion auch dazu herangezogen werden, die für den jeweiligen Fahrzeugbenutzer individuellen Einstel¬ lungen der genannten Kraftfahrzeug-Elemente vorzunehmen. Da der Fahrzeugbenutzer stets nur seine persönliche Chipkarte zur Hand hat, ist damit die Gefahr einer eventuellen Fehleinstellung der genannten Elemente als Folge einer falschen Chipkarte ausgeschlossen.A particularly advantageous design of the electronic memory results if it is contained in a chip card. Chip cards are becoming increasingly important and are used as a means of payment or settlement. In the context of the invention, in addition to the usual function, they can also be used to make the individual settings of the motor vehicle elements mentioned for the respective vehicle user. Since the vehicle user always only has his personal chip card at hand, there is a risk of one possible incorrect setting of the elements mentioned as a result of an incorrect chip card excluded.
Schließlich beschäftigt sich eine weitere Ausgestaltung der Erfindung mit der Vereinfachung des mechanischen Aufbaus unter der Voraussetzung, daß eine Chipkarte Verwendung findet. Wird diese vollständig in einer Öffnung des Sender-Körpers aufgenommen, so ist sie damit gegenüber Beschädigungen und Veränderungen ihres Spei¬ cherinhalts mit Hilfe externer magnetischer Felder weitgehend geschützt.Finally, a further embodiment of the invention deals with the simplification of the mechanical structure provided that a chip card is used. If this is received completely in an opening in the transmitter body, it is thus largely protected against damage and changes to its contents by means of external magnetic fields.
Innerhalb des Sender-Gehäuses ist es damit lediglich erforderlich, den Inhalt des elektronischen Speichers auszulesen. Dies kann in der Weise erfolgen, wie es in der DE-OS 36 27 194 für das Zusammenspiel zwischen dem als Chipkarte ausgebildeten Sender und dem kraftfahrzeugeigenen Empfänger beschrieben ist. Es ist im Rahmen der Erfindung dann lediglich erforderlich, innerhalb des Sender-Gehäuses selbst einen Empfänger vorzusehen, der beispielsweise auf ein entsprechendes Sendesignal hin das Auslesen des Speicherinhalts der Chipkarte veranlaßt. Dieser Speicherinhalt wird innerhalb des Sender-Gehäuses in den entsprechenden Anteil des Codesignals umgesetzt und durch den Sender an das Kraftfahrzeug ausgesandt.Within the transmitter housing, it is only necessary to read out the content of the electronic memory. This can be done in the manner described in DE-OS 36 27 194 for the interaction between the transmitter designed as a chip card and the vehicle's own receiver. It is then only necessary within the scope of the invention to provide a receiver within the transmitter housing itself, which, for example, causes the memory content of the chip card to be read out in response to a corresponding transmission signal. This memory content is converted into the corresponding portion of the code signal within the transmitter housing and transmitted to the motor vehicle by the transmitter.

Anwendungsmöglichkeiten der erfindungsgemäßenApplications of the invention
Sicherheitseinrichtung zu erweitern. Hierzu ist derExpand safety device. For this is the
(tragbare) Sender zusätzlich mit einem Empfänger und einem Speicher für ein Codesignal mit fahrzeug- und/oder benutzerspezifischem -Dateninhalt versehen. Dieses Codesignal wird vom Kraftfahrzeug unmittelbar vor bzw. nach dem vom Sender ausgesandten Codesignal ausgesandt und im Empfänger gespeichert. Dabei ist es sinnvoll, die fahrzeugspezifischen Daten in Verbindung mit dem für den Anteil des Codesignals zu speichern, der den Zustand der Diebstahlschutzeinrichtungen steuert. Entsprechend sind die fahrzeugbenutzerspezifischen Daten in Verbindung mit dem anderen Anteil des Codesignals festzuhalten. Sofern für letzteres ein Speicher in einem separaten mechanischen Teil vorgesehen ist, können somit die fahrzeugbenutzerspezifischen Daten auch unabhängig von den fahrzeugspezifischen Daten verarbeitet werden. Dies ist beispielsweise in einer Werkstatt oder in einer Kundendienst-Annahmestelle möglich.(Portable) transmitters additionally provided with a receiver and a memory for a code signal with vehicle and / or user-specific data content. This code signal is transmitted by the motor vehicle immediately before or after the code signal transmitted by the transmitter and stored in the receiver. It makes sense that to store vehicle-specific data in conjunction with that for the portion of the code signal that controls the state of the anti-theft devices. Accordingly, the vehicle user-specific data must be recorded in connection with the other part of the code signal. If a memory is provided in a separate mechanical part for the latter, the vehicle user-specific data can thus also be processed independently of the vehicle-specific data. This is possible, for example, in a workshop or in a customer service acceptance point.
Damit wird es beispielsweise möglich, Informationen, die sich aus und über die individuelle Benutzung des Kraftfahrzeugs ergeben, ohne weiteres auszuwerten. Hierzu gehören die vom Fahrzeugbenutzer zurückgelegte Wegstrecke, sein Fahrverhalten oder zusätzliche Informationen, die sich aus dem Wechselspiel zwischen Fahrer und Fahrzeug ergeben. Letzteres gilt beispielsweise für einen Defekt, der vom Kraftfahrzeug zwar angezeigt wurde, vom Fahrzeugbenutzer jedoch lediglich durch Unterdrücken der Anzeige berücksichtigt wurde.This makes it possible, for example, to easily evaluate information that results from and about the individual use of the motor vehicle. This includes the distance traveled by the vehicle user, his driving behavior or additional information that results from the interplay between driver and vehicle. The latter applies, for example, to a defect that was displayed by the motor vehicle, but was only taken into account by the vehicle user by suppressing the display.
Die Erfindung ist anhand der Zeichnung weiter erläutert. Es zeigt:The invention is further illustrated by the drawing. It shows:
Fig. 1 den prinzipiellen mechanischen Aufbau eines tragbaren Senders, der im Rahmen der erfin¬ dungsgemäßen Sicherheitseinrichtung verwandt wird,1 shows the basic mechanical structure of a portable transmitter which is used in the context of the safety device according to the invention,
Fig. 2 schematisch die Wirkungsweise der erfindungsgemäßen Sicherheitseinrichtung und Fig. 3 schematisch eine Ausbaustufe der erfindungsgemäßen Sicherheitseinrichtung.Fig. 2 shows schematically the operation of the safety device according to the invention and Fig. 3 schematically shows an expansion stage of the safety device according to the invention.
Der in Fig. 1 gezeigte Sender 1' für ein drahtlos über¬ tragbares Codesignal sitzt in einem Gehäuse 1, das die zum Senden und Empfangen eines Codesignals und dem Erzeugen bzw. Umsetzen dieser Signale erforderlichen elektronischen Elemente besitzt (nicht dargestellt) . Der konstruktive Aufbau kann im Detail beispielsweise aus der DE-OS 36 27 194 entnommen werden. Das Gehäuse 1 dient ferner zur Aufnahme einer Chipkarte 2, die über eine Öffnung 3 in das Gehäuse 1 einschiebbar ist und im eingeschobenen Zustand vollständig im Gehäuse 1 enthal¬ ten ist. Die Chipkarte 2 enthält einen elektronischen Speicher (PROM, nicht dargestellt) , in dem Daten zum Einstellen von Bedien- und Benutzungselementen des Kraftfahrzeugs enthalten sind. Bei diesen Elementen handelt es sich beispielsweise um die Zentralverriege¬ lung, die Höhen- und Längseinstellung der Lenksäule und die Heiz- und Klimaanlage.The transmitter 1 'shown in FIG. 1 for a wirelessly transmissible code signal is seated in a housing 1 which has the electronic elements required for transmitting and receiving a code signal and for generating or converting these signals (not shown). The design can be found in detail, for example, from DE-OS 36 27 194. The housing 1 also serves to hold a chip card 2, which can be inserted into the housing 1 via an opening 3 and is completely contained in the housing 1 in the inserted state. The chip card 2 contains an electronic memory (PROM, not shown) in which data for setting operating and use elements of the motor vehicle are contained. These elements are, for example, the central locking, the height and length adjustment of the steering column and the heating and air conditioning system.
Innerhalb des Gehäuses 1 befindet sich ferner ein Empfänger, über den einerseits ein externes Codesignals aufgenommen und verarbeitet werden kann und über den ferner der Inhalt des elektronischen Speichers der Chipkarte 2 ausgelesen wird. Ferner ist innerhalb des Gehäuses 1 ein Sender enthalten, der ein aus zwei Anteilen zusammengesetztes Codesignal erzeugt und drahtlos, z. B. als Infrarot- bzw. Hochfrequenzsignal abgibt. Einer der beiden Anteile ist dabei nach einem vorgegebenen Algorithmus gebildet und stellt die Be- nutzerIdentifizierung dar, mit deren Hilfe die Dieb¬ stahlschutzeinrichtung des Kraftfahrzeugs entriegelt wird. Der andere Anteil ist charakteristisch für den jeweiligen Fahrzeugbenutzer und wird aus dem Speicher- inhalt des elektronischen Speichers der Chipkarte 2 gebildet. Er dient dazu, die genannten Bedien- und Benutzungselemente des Kraftfahrzeugs benutzerindivi¬ duell einzustellen.Within the housing 1 there is also a receiver via which an external code signal can be received and processed on the one hand and via which the content of the electronic memory of the chip card 2 is also read out. Furthermore, a transmitter is included within the housing 1, which generates a code signal composed of two parts and wireless, z. B. emits as an infrared or radio frequency signal. One of the two parts is formed according to a predetermined algorithm and represents the user identification with the aid of which the anti-theft device of the motor vehicle is unlocked. The other part is characteristic of the respective vehicle user and is derived from the storage content of the electronic memory of the chip card 2 is formed. It serves to set the above-mentioned operating and usage elements of the motor vehicle in a user-specific manner.
Das vom Sender ausgesandte zweiteilige Codesignal gelangt über eine Antenne des Kraftfahrzeugs in eine Auswerteeinheit , die einen Sender sowie einen Em¬ pfänger enthält. Die Antenne ihrerseits kann in der Fahrertür, der Beifahrertür und/oder der Heckklappe des Kraftfahrzeugs sitzen. In der Nähe der Antenne befindet sich ferner ein Schaltkontakt, bei dem es sich um einen Türgriff-Kontakt 4 bzw. 5 sowie um einen Heck¬ klappen-Schloßtaster 6 handelt. Wird dieser Kontakt betätigt, so wird die Auswerteeinheit 4 veranlaßt, einen Fragecode über die Antennen 1 bis 3 auszusenden. Der tragbare Sender 1 ' empfängt diesen Fragecode und wird dadurch veranlaßt, seinen zweigeteilten Code auszusen¬ den. Stimmt der erste Anteil, der für die Diebstahl¬ schutzeinrichtungen zuständig ist, mit dem erwarteten Codesignal überein, so veranlaßt die Auswerteeinheit 4 die Entriegelung der Diebstahlschutzeinrichtungen. Damit wird die Verriegelung der Fahrertür, aller anderen Türen, der Heckklappe sowie ferner des Zünd- und Lenk¬ radschlosses veranlaßt.The two-part code signal emitted by the transmitter arrives via an antenna of the motor vehicle in an evaluation unit which contains a transmitter and a receiver. The antenna in turn can sit in the driver's door, the passenger door and / or the tailgate of the motor vehicle. In the vicinity of the antenna there is also a switch contact, which is a door handle contact 4 or 5 and a tailgate lock button 6. If this contact is actuated, the evaluation unit 4 is prompted to send out a question code via the antennas 1 to 3. The portable transmitter 1 'receives this question code and is thereby caused to transmit its two-part code. If the first part, which is responsible for the theft protection devices, matches the expected code signal, the evaluation unit 4 initiates the unlocking of the theft protection devices. This causes the driver's door, all other doors, the tailgate and also the ignition and steering wheel lock to be locked.
Mit Hilfe des zweiten Anteils des vom Sender 1' ausge¬ sandten Codesignals wird ferner eine fahrerindividuelle Einstellung von nicht im einzelnen gezeigten Bedien¬ bzw. Benutzungselementen des Kraftfahrzeugs vorgenommen.With the aid of the second part of the code signal sent by the transmitter 1 ', a driver-specific setting of operating or use elements of the motor vehicle, which are not shown in detail, is also carried out.
Neben dem zweigeteilten Codesignal kann der Sender 1 ' Zusatzfunktionen auslösen. Hierzu dienen Tasten 7 bis 10, bei deren Betätigen die Änderung des Zustands der Diebstahlschutzeinrichtung aus größerer Entfernung (Taste 7) , die Fernbedienung von Einrichtungen außerhalb des Kraftfahrzeugs wie beispielsweise einem Garagentor (Taste 8) sowie die Fernbedienung weiterer Einrichtungen des Kraftfahrzeugs, wie beispielsweise der Fensterheber (Tast 9) und der Außenbeleuchtungsanlage (Taste 10) veranlaßt wird.In addition to the two-part code signal, the transmitter 1 'can trigger additional functions. This is done using buttons 7 to 10, when pressed, the change in the state of the anti-theft device from a greater distance (button 7), the remote control of devices outside the motor vehicle such as a garage door (key 8) and the remote control of other devices of the motor vehicle, such as the window regulator (key 9) and the exterior lighting system (key 10).
Damit ergibt sich ein ultifunktionaler automatischer Schlüssel, dessen zentrale Funktion im Aussenden eines aus zwei Anteilen bestehenden Codesignals besteht, dessen einer Anteil zum Bedienen der Diebstahlschutz- einrichtung und dessen anderer Anteil zum benutzerindi¬ viduellen Einstellen von Bedien- und Benutzungselementen des Kraftfahrzeugs dient. Der letztere Anteil wird mit Hilfe einer Chipkarte gewonnen, die im Gehäuse 1 ein¬ gesteckt ist und in einem Speicher die Daten zum Ein- stellen der genannten Elemente enthält. Diese Daten werden beispielsweise in einer Werkstatt oder einer Kundendienststelle mit Hilfe eines geeigneten Schreib-/ Lesegeräts in den Speicher bleibend eingegeben.This results in an ultimate functional automatic key, the central function of which is to send out a code signal consisting of two parts, one part of which serves to operate the anti-theft device and the other part of which is used for user-individually setting operating and use elements of the motor vehicle. The latter part is obtained with the aid of a chip card which is inserted in the housing 1 and contains the data for setting the elements mentioned in a memory. This data is permanently entered into the memory, for example in a workshop or a customer service point, using a suitable read / write device.
Die in Fig. 3 dargestellte Erweiterung der Sicherheitseinrichtung zeigt schematisch den Aufbau eines Gesamtsystems mit wechselseitigen Sende- und Empfangsmöglichkeit zwischen dem Sender 1 ' , einem Kraftfahrzeug 11 sowie weiteren externen Einrichtungen. Bei letzterem handelt es sich beispielsweise um ein Schreib-/Lesegerät 12 in einer Werkstatt oder dgl..The extension of the safety device shown in FIG. 3 schematically shows the structure of an overall system with mutual transmission and reception options between the transmitter 1 ', a motor vehicle 11 and other external devices. The latter is, for example, a read / write device 12 in a workshop or the like.
Der Sender 1* besteht aus einem Teil 1, das dazu dient, den für die Benutzeridentifizierung erforderlichen Anteil des ausgesandten Codesignals festzulegen. Das Teil 1 enthält nunmehr neben einem Sende- auch einen Empfangsteil, das ls kombiniertes Sende-/Empfangsteil (S/E-Teil) dargestellt ist. Ferner sind im Teil 1 die Tasten 7 bis 10 bzw. ihre nachgeschaltete Schaltelemente, ein nicht flüchtiger (NV-)Speicher sowie eine zugehörige Steuerung enthalten.The transmitter 1 * consists of a part 1, which serves to determine the portion of the transmitted code signal required for the user identification. In addition to a transmitting part, part 1 now also contains a receiving part, which is shown as a combined transmitting / receiving part (S / E part). Furthermore, in part 1, the keys 7 to 10 or their downstream Switching elements, a non-volatile (NV) memory and an associated control included.
Der Sender 1 ' enthält ferner die Chipkarte 2, die ebenfalls mit einem Sende-/Empfangsteil, einem nicht flüchtigen Speicher sowie einer Steuerung versehen ist. Die Teile 1 und 2 tauschen untereinander Daten aus. Zwischen dem Sender 1' und dem Kraftfahrzeug 11 ist bidirektional ein Datenaustausch möglich. Damit werden einerseits die Daten des in den nicht flüchtigen Speicher der Teile 1 und 2 enthaltenen Daten zum Kraftfahrzeug hin übertragen und umgekehrt vom Kraftfahrzeug die in diesen Speichern enthaltenen Daten abgefragt bzw. aktualisiert. Die Aufteilung der Daten ist dabei zweckmäßigerweise so vorgenommen, daß in der Chipkarte 2 die benutzerindividuellen Daten gespeichert werden. Diese Daten können wiederum extern durch das Schreib/Lese-Gerät 12 eingegeben bzw. aktualisiert werden. Damit ist es möglich, benutzerindividuelle Daten bereits vor der erstmaligen Benutzung des Kraftfahrzeugs vorzugeben bzw. zwischen verschiedenen . Benutzungen entsprechende Daten extern auszulesen und weiterzuverarbeiten. Auf diese Weise ist ein Höchstmaß von Komfort für den Fahrzeugbenutzer sowohl bei der Benutzung des Kraftfahrzeugs als auch vor und nach diesen Benutzungen möglich. The transmitter 1 'also contains the chip card 2, which is also provided with a transmitting / receiving part, a non-volatile memory and a controller. Parts 1 and 2 exchange data with each other. A bidirectional data exchange is possible between the transmitter 1 'and the motor vehicle 11. Thus, on the one hand, the data of the data contained in the non-volatile memory of parts 1 and 2 are transmitted to the motor vehicle and, conversely, the data contained in these memories are queried or updated by the motor vehicle. The division of the data is expediently carried out in such a way that the user-specific data are stored in the chip card 2. This data can in turn be entered or updated externally by the read / write device 12. It is thus possible to specify user-specific data even before the motor vehicle is used for the first time or between different ones. Reading out and processing the corresponding data externally. In this way, a maximum of comfort for the vehicle user is possible both when using the motor vehicle and before and after these uses.
