Abstract

L’invention concerne un procédé d’échanges d’informations entre un système radar d’un véhicule et un système radar d’un autre véhicule, le procédé comprenant des étapes de :- réception (310) d’un signal radiofréquence par le système radar du véhicule ;- détermination (320) du type de signal radiofréquence reçu pour savoir si le signal radiofréquence reçu est un signal radiofréquence réfléchi ou un signal radiofréquence émis par le système radar de l’autre véhicule ; et- si le signal radiofréquence reçu est un signal radiofréquence réfléchi, fonctionnement (330) du système radar du véhicule en mode écho ;- si le signal radiofréquence reçu est un signal radiofréquence émis par le système radar de l’autre véhicule, basculement (340) du fonctionnement du système radar du véhicule en mode dialogue. Figure pour l’abrégé : Figure 4The invention relates to a method of exchanging information between a radar system of a vehicle and a radar system of another vehicle, the method comprising the steps of:- reception (310) of a radio frequency signal by the system radar of the vehicle; - determining (320) the type of radio frequency signal received as to whether the radio frequency signal received is a reflected radio frequency signal or a radio frequency signal emitted by the radar system of the other vehicle; and- if the received radio frequency signal is a reflected radio frequency signal, operating (330) the vehicle's radar system in echo mode;- if the received radio frequency signal is a radio frequency signal transmitted by the other vehicle's radar system, switching (340 ) operation of the vehicle's radar system in dialogue mode.
