Abstract

L'invention concerne un procédé pour afficher une disponibilité d'un premier mode de conduite d'un véhicule (1), le véhicule pouvant fonctionner au moins dans le premier mode de conduite, dans lequel le véhicule (1) est piloté au moins en partie automatiquement, et dans un second mode de conduite, dans lequel le véhicule (1) n'est pas piloté automatiquement. Selon le procédé de l'invention, on détecte si le véhicule se trouve dans le premier ou le second mode de conduite. On détermine des premières données environnementales autour du véhicule (1). Si on détecte que le véhicule (1) se trouve dans le second mode de conduite, on prévoit sur la base des premières données environnementales un début de portion de voie à partir duquel le premier mode de conduite est disponible. En fonction du début prévu de la portion de voie, on génère sur une première zone d'affichage (3) un premier élément d'affichage (13) qui représente le début prévu de la portion de voie dans un premier mode de présentation. En outre, l'invention concerne un dispositif (2) destiné à afficher une disponibilité d'un premier mode de conduite d'un véhicule (1).
