Abstract

L'invention concerne un dispositif (110) destiné à l'affichage d'informations et un procédé de commande de ce dispositif. L'affichage d'informations est effectué à l'aide à la fois d'un moyen d'affichage, par ex. sous forme d'un écran, et d'un moyen de projection piloté par une unité de commande, ce moyen de projection permettant de projeter les informations sur une zone située à l'extérieur du dispositif. L'invention est caractérisée en ce qu'en tant qu'information, un paramètre de fonctionnement du véhicule est projeté sur la chaussée (130).
