Abstract

L’invention concerne un procédé d’émission d’un message de freinage d’urgence d’un premier véhicule à destination d’un second véhicule, le premier et le second véhicule embarquant chacun un système radar, le procédé comprenant des étapes de :- établissement (410) d’une connexion radiofréquence entre le système radar du premier véhicule et le système radar du second véhicule fonctionnant tous les deux en mode dialogue ;- obtention (420) périodique d’une position relative du premier véhicule par rapport au second véhicule par le système radar du premier véhicule fonctionnant en mode écho ;- émission (430) par le système radar du premier véhicule fonctionnant en mode dialogue d’un signal radiofréquence porteur d’un message de freinage d’urgence si la position relative du premier véhicule par rapport au second véhicule devient inférieure à une valeur seuil.
