Abstract

Abstract Translated from German Bei einer Diebstahlsicherungsvorrichtung für Kraftfahrzeuge mit drahtlos übertragenem Codesignal wird dieses außerhalb des Kraftfahrzeuges in geeigneter Weise von einem Zweitsignal überlagert, das im bzw. am Kraftfa zeug nicht empfangen werden soll. Dadurch wird ein wirksamer Schutz vor Abhören des Codesignals erzielt. In an anti-theft device for motor vehicles with wirelessly transmitted code signal, this is superimposed in a suitable manner outside the motor vehicle by a second signal which is in or on the motor vehicle stuff should not be received. This provides effective protection against eavesdropping on the code signal.
