Vehicle anti-theft system and method, and application of this system for managing a fleet of vehicles
First Claim
1. Vehicle anti theft system, comprising:
- an immobilizing transponder integrated in the vehicle, an electronic label intended to communicate with the transponder, and connection means which are able to establish or interrupt the communication between the transponder and the electronic label in response to orders coming from a control unit, characterized in that the connection means include;
a first antenna close to the transponder, a second antenna close to the electronic label, and an electrical connection equipped with a switch and connecting the two antennae, the switch being controlled by the control unit.

Abstract
A vehicle anti-theft system, includes in a passive relay enabling an electronic label (2) usually identified when proximate to a transponder (1) to be offset. The electronic label (2) is integrated in a reinforced casing. Communication between the label and the transponder (1) is set up via an antenna (4) proximate the transponder (1), an electric cable and a second antenna (5) proximate the label. The cable includes an electromechanical switch enabling a control switch (8) to interrupt or set up the radio link. The invention therefore provides a novel anti-theft system for which the installation is entirely reversible and having no damaging effect on the vehicle since it does not require disconnecting a vehicle cable and entails no splicing.

13. Method for immobilizing a vehicle having an immobilizing transponder, this transponder being intended to communicate with an electronic label integrated in the vehicle;
- in which the communication between the transponder and the electronic label is established or interrupted in response to orders coming from a control unit, characterized in that the communication is established or interrupted by controlling a switch which electrically connects a first antenna close to the transponder to a second antenna close to the electronic label.
