Abstract

Selon l'invention, un procédé de communication entre des véhicules (FF, PF1, PF2) comporte l'envoi d'un appel de réveil (W1) depuis un premier véhicule (FF) à au moins un second véhicule (PF1) dans l'environnement du premier véhicule (FF). Lorsque le ou les seconds véhicules (PF1) ont reçu l'appel de réveil (W1) du premier véhicule (FF), le réveil d'un système de communication (K) du ou des seconds véhicules (PF1) est effectué. Lorsque le ou les seconds véhicules (PF1) ont reçu l'appel de réveil (W1) du premier véhicule (FF), des données d'un modèle de l'environnement sont envoyées par le ou les seconds véhicules (PF1) au premier véhicule (FF), les données du modèle de l'environnement du ou des seconds véhicules (PF1) décrivent l'environnement du ou des seconds véhicules (PF1).
