FERNSTEUERUNGS-SCHLÜSSEL FÜR KRAFTFAHRZEUGEREMOTE CONTROL KEYS FOR MOTOR VEHICLES

Die vorliegende Erfindung betrifft ein Fernsteuerungs-Schlüssel für Kraftfahrzeuge, insbesondere ein Fernsteuerungs-Schlüssel zum öffnen des Türschlosses oder des Zündschalter an einem Kraftfahrzeug sowohl direkt als auch aus einer Entfernung.The present invention relates to a remote control key for motor vehicles, in particular a remote control key for opening the door lock or the ignition switch on a motor vehicle both directly and from a remotely.

Die herkömmlichen Zündschalter in irgendwelchen Modellen von Kraftfahrzeugen werden gewöhnlich durch einen Schlüssel an- und abgeschaltet. Sobald der Zündschalter durch den Schlüssel angeschaltet ist, wird die Stromversorgung der Batterie sofort mit dem internen elektrischen Stromkreis angeschlossen, um den Motor anzulassen. Der Schlüssel muss jedoch in das Schlüsselloch der Zündschaltung gesteckt und in eineThe conventional ignition switches in any model of automobiles are usually turned on and off by a key. Once the ignition switch is turned on by the key, the power supply of the battery is immediately connected to the internal electrical circuit to start the engine. However, the key must be inserted into the keyhole of the ignition circuit and inserted into a

Richtung gedreht werden, um den Zündschalter einzuschalten. Der Benutzer muss vielleicht mehrere Male versuchen, den Schlüssel in das Schlüsselloch zu stecken.direction to turn the ignition switch on. The user may have to try several times to insert the key into the keyhole.

Verschiedene Fernsteuerungen sind im übrigen bekannt und finden praktisch überall zur Schaltung der Motorfahrzeug-Türschlösser ihre Anwendung. Verglichen mit den Schlüsseln für Türschlösser an Autos sind diese Fernsteuerungen für Kraftfahrzeuge schwer. Ein Kraftfahrzeug-Schlüssel eignet sich aus diesem Grund eher zum Mitnehmen als eine solche Fernsteuerung.Various remote controls are also known and are used practically everywhere to operate motor vehicle door locks. Compared to keys for car door locks, these remote controls for motor vehicles are heavy. For this reason, a motor vehicle key is more suitable for carrying around than such a remote control.

Die vorliegende Erfindung wurde unter den obengenannten Umständen vollendet. Die Erfindung dient zum Integrieren der Fernsteuerung in den Schlüssel, so dass der Schlüssel zum öffnen des kraftfahrzeuges sowohl direkt als auch aus einer Entfernung gebraucht werden kann. Der Funksignal-Schaltkreis ist im Innern des Schlüsselgriffes eingesetzt und wird durch einen Schaltknopf, der ein Funksignal zum öffnen des Kraftfahrzeuges vom metallenen Schlüsselbart aussendet, betätigt. Eine Anzeigeleuchte, welche auf dem Griff des Schlüssels aufgesetzt und mit dem Schaltkreis verbunden ist, leuchtet auf, wenn die Fernsteuerung im Schlüssel betätigt wird.The present invention has been completed under the above circumstances. The invention serves to integrate the remote control into the key so that the key can be used to open the motor vehicle both directly and from a distance. The radio signal circuit is installed inside the key handle and is operated by a switch button that sends a radio signal for opening the motor vehicle from the metal key bit. An indicator lamp, which is mounted on the handle of the key and connected to the circuit, lights up when the remote control in the key is operated.

Figur 1: Fernsteuerungs-Schlüssel, der im allgemeinen aus einem metallenen Schlüsselbart 12 besteht, welcher mit dem Plastick-Griff 11 verbunden ist, und aus einem Schaltkreis (nicht gezeigt), die im Griff 11 eingebaut ist. Der Griff 11 ist aussen mit einem Schaltknopf 13 und einer Anzeigeleuchte IAFigure 1: Remote control key, which generally consists of a metal key bit 12 connected to the plastic handle 11 and a circuit (not shown) built into the handle 11. The handle 11 is provided on the outside with a switch button 13 and an indicator light IA

versehen, welche dementsprechend am Schaltkreis angeschlossen sind.which are accordingly connected to the circuit.

Figur 2: Eine elektronische Knopfbatterie dient in der vorliegenden Erfindung als StromversorgungFigure 2: An electronic button battery serves as a power supply in the present invention

15. Die Stromversorgung 15 ist an einer Anzeige-Schaltung 16 und einer Encode-IC 17 über den obengenannten Schaltknopf 13 angeschlossen. Eine Hochfrequenz-Modulationsschaltung 18 ist am Pluspol der Stromversorgung 15 angeschlossen.15. The power supply 15 is connected to a display circuit 16 and an encoder IC 17 via the above-mentioned switch button 13. A high frequency modulation circuit 18 is connected to the positive terminal of the power supply 15.

Figur 3: Der Encode-IC 17 dient zum Kodieren von 8-bit-Koden, wobei jeder Kode aus A0-A7 zusammengesetzt ist. Die Koden sind gemäss einer der drei Kontaktverhältnissen der Pole des Encode-IC 17 eingestellt, nämlich der Erdung, des Contact Float oder des positiven Stromanschlusses. Dies ermöglicht eine Kodierung vieler Ziffern der Koden. Die Einstellung eines bestimmten Kodes muss deshalb genau mit dem Kode des entesprechenden Empfängers abgestimmt sein, so dass das zu steuernde Ziel von anderen unterschieden werden kann.Figure 3: The encoder IC 17 is used to encode 8-bit codes, each code being composed of A0-A7. The codes are set according to one of the three contact relationships of the poles of the encoder IC 17, namely ground, contact float or positive power connection. This enables encoding of many digits of the codes. The setting of a specific code must therefore be precisely coordinated with the code of the corresponding receiver so that the target to be controlled can be distinguished from others.

Die Hochfrequenz Modulationsschaltung 18 muss direkt am Pluspol der Stromversorgung 15 durch den Schaltknopf 13 angeschlossen sein, um einen Frequenzausgleich während der Betätigung des Fernsteuerungs-Schlüssels 10 auszuschalten. Die Stromversorgung 15 ist mit der Anzeige-Schaltung 16 verbunden und der Encode-IC 17 durch den Schaltknopf 13.The high frequency modulation circuit 18 must be connected directly to the positive pole of the power supply 15 through the switch button 13 in order to switch off frequency compensation during operation of the remote control key 10. The power supply 15 is connected to the display circuit 16 and the encoder IC 17 through the switch button 13.

Beim Auslösen aktiviert der Widerstand Rl die Anzeigeleuchte 14, die aufleuchtet, um die Funktion des Fernsteuerungs-Schlüssels 10 anzueigen. An der Leuchtkraft der Anzeigeleuchte IA kann der Benutzer sehen, wann und ob die Knopfbatterie ausgewechselt werden muss. Da der Strom durch den Stift Nr. 17 des Encoder-IG 17 einfliesst, wird der Stift Nr. 15 sofort durch den Stift Nr. 17 angetrieben. Ein dem vorher eingestellten Kode entsprechendes Ausgangssignal wird dann durch den Stift Nr. 15 ausgelöst und an einen Schwingungskreis, der aus einem Transistor Ql, einem Kondensator C3 und diner Induktanz L2 besteht, über den Widerstand R2 abgegeben. Da die Signale des Encode-IC aus Digitalsignalen bestehen, fängt der Schwingungskreis zu schwingen an, wenn das Signal "1" ist bzw, hört auf zu schwingen wenn das Signal "0" ist. Ein komplettes Amplitude-Modulationssignal wird ausgelöst, da dieser Vorgang immer wiederholt wird. Das Signal wird dann von der Induktanz L2 durch den Schlüsselbart 12 - die als Übertragungsantenne selbst funktioniert - ausgesendet.When triggered, the resistor Rl activates the indicator lamp 14, which lights up to indicate the function of the remote control key 10. The brightness of the indicator lamp IA allows the user to see when and if the button battery needs to be replaced. Since the current flows in through pin No. 17 of the encoder IG 17, pin No. 15 is immediately driven by pin No. 17. An output signal corresponding to the previously set code is then triggered by pin No. 15 and delivered to an oscillation circuit consisting of a transistor Ql, a capacitor C3 and an inductance L2 via resistor R2. Since the signals of the encoder IC consist of digital signals, the oscillation circuit starts to oscillate when the signal is "1" and stops oscillating when the signal is "0". A complete amplitude modulation signal is triggered as this process is repeated over and over. The signal is then transmitted from the inductance L2 through the key bit 12 - which functions as a transmission antenna itself.

Durch das Betätigen des Schaltknopfes 13 wird das Kodesignal durch den SchlüsselbartBy pressing the button 13, the code signal is transmitted through the key bit

(Übertragungsantenne) 12 ausgesendet und die entsprechende Schaltvorrichtung am Kraftfahrzeug aus(transmission antenna) 12 and the corresponding switching device on the motor vehicle
