  • the invention relates to a device consisting of at least two components for determining whether an object, in particular a vehicle, which is connected to one of the two components, has been stolen or not.
  • Such devices are known for example to prevent shoplifting.

  • DE-OS 36 05 697 proposes to store important vehicle-related data in vehicles with diagnostic electronics and in police controls, border crossings or visits to the workshop, to query these data and to compare or determine them with a list of vehicles reported as stolen whether the approval numbers match the stored matches, etc.

  • a passive transponder is present in the vehicle which, after receiving an activation signal which is periodically emitted by a checking station, sends an encrypted response which is checked by the checking unit for its validity, that if the answer is valid, the The driver is prompted to issue a code corresponding to the transponder arranged in the vehicle, which in turn is checked for validity by the checking unit and that the result and, if appropriate, the progress of the checking is displayed on a display unit.

Since, for safety reasons, the vehicle transponder has no connection to the vehicle's electrical system, that is to say it works completely autonomously, switching off the power level leads to a minimization of the power consumption and an extension of the intervals between battery replacement and recharging. It is entirely possible to provide an energy supply that works over the entire expected lifespan of the transponder. If the microprocessor 3 determines, when checking the received signal, that it is not a valid activation signal, the switch 4 remains in its interrupted position and the transmitting part remains completely passive.

Abstract

L'invention concerne un dispositif composé d'au moins deux éléments, servant à déterminer si un objet, notamment un véhicule, relié à un des deux éléments, a été dérobé ou non. Selon l'invention, il est prévu qu'un transpondeur passif se trouve monté sur l'objet et qu'à réception d'un signal d'activation diffusé périodiquement par un poste de contrôle, il émette comme réponse, un code-objet codé dont l'unité de contrôle vérifie la validité. Si le code-objet est juste, la personne à qui appartient l'objet à protéger est invitée à transmettre un code personnel correspondant au transpondeur placé sur l'objet. Ce code personnel est lui aussi vérifié par l'unité de contrôle. Le résultat et éventuellement la suite de la procédure d'évaluation sont indiqués sur une unité d'affichage.
