Abstract

L’invention a pour objet un procédé de communication entre un module de communication (1) d’un véhicule et un dispositif d’authentification. Le module de communication (1) comprend une unique antenne (11), un circuit de contrôle (12) de ladite antenne (11), un faisceau (13) de câbles permettant notamment d’alimenter le module de communication (1) en énergie électrique, un ensemble (14) d’éléments en ferrite permettant de réduire les rayonnements électromagnétiques émis par ledit faisceau (13) et un module de commutation (15) apte à connecter ou non électromagnétiquement l’ensemble (14) d’éléments en ferrite entre le faisceau (13) et le module de communication (1). Le procédé comprend une étape de commutation entre un premier mode de fonctionnement, dans lequel le faisceau (13) est relié électriquement au module de communication (1) via l’ensemble (14) d’éléments en ferrite, et un deuxième mode de fonctionnement, dans lequel l’ensemble (14) d’éléments en ferrite est court-circuité de sorte que le faisceau (13) est relié électriquement directement au module de communication (1). Figure pour l’abrégé : Fig. 1The subject of the invention is a method of communication between a communication module (1) of a vehicle and an authentication device. The communication module (1) comprises a single antenna (11), a control circuit (12) of said antenna (11), a bundle (13) of cables making it possible in particular to supply the communication module (1) with energy electrical, a set (14) of ferrite elements making it possible to reduce the electromagnetic radiation emitted by said beam (13) and a switching module (15) capable of electromagnetically connecting the set (14) of ferrite elements or not between the harness (13) and the communication module (1). The method comprises a step of switching between a first operating mode, in which the bundle (13) is electrically connected to the communication module (1) via the assembly (14) of ferrite elements, and a second operating mode , wherein the set (14) of ferrite elements is short-circuited so that the harness (13) is electrically connected directly to the communication module (1).
