Abstract

Ein Verfahren zur Code-Sicherung bei einem elektroni­ schen Schlüssel besteht darin, daß im Sender (1) und im Empfänger (2) eine Anzahl von Code-Nummern 1 bis n gespeichert sind, wobei nach jedem Sende- und Empfangs­ vorgang im Sender (1) und Empfänger (2) eine neue übereinstimmende Code-Nummer selbsttätig eingestellt wird. Der Sender (1) steuert über einen Verstärker (3) eine Fotodiode (4) an, welche ein codiertes Infrarot-Signal (5) aussendet. Dieses Signal (5) wird von einem Fototransistor (6) aufgenommen, der es über einen Verstärker (7) dem Empfänger (2) zuleitet. Am Ausgang (8) des Empfängers (2) steht ein Signal (9) an, mit welchem die Zentralverriegelung eines Kraftfahrzeuges betätigt wird.
