Abstract

L'invention concerne un dispositif d'affichage pour un véhicule et son procédé de fonctionnement. Un dispositif d'affichage pour un véhicule selon un mode de réalisation de la présente invention comprend : de multiples unités d'affichage formées sur le côté avant du corps principal et formées pour pouvoir être montées sur un tableau de bord de véhicule ; et un processeur. Les multiples unités d'affichage comprennent : une première unité d'affichage ; une deuxième unité d'affichage, dont une partie peut être courbée ; et une troisième unité d'affichage ayant une taille d'écran d'affichage qui est variable. Lorsque la conduite du véhicule est détectée tandis que la deuxième unité affichage parmi les multiples unités d'affichage est dans un premier facteur de forme qui est plat, le processeur commande la deuxième unité d'affichage pour qu'elle passe à un second facteur de forme qui est différent du premier facteur de forme. De plus, le processeur peut déterminer qu'il existe une demande de passage au second facteur de forme sur la base d'au moins un élément parmi des données de détection du véhicule, du contenu affiché sur les multiples unités d'affichage et une demande d'entrée. Dans un tel cas, le processeur peut identifier si un passage au second facteur de forme est possible sur la base d'une situation de conduite du véhicule, et peut commander les multiples unités d'affichage pour passer au facteur de forme en fonction de la détermination.
