Abstract

L'invention porte sur un affichage tête haute comprenant : un moyen d'acquisition d'informations de circulation, qui obtient des informations relatives à un encombrement et/ou aux restrictions de circulation qui sont présentes plus loin en avant d'une pluralité de routes de bifurcation qui partent d'une bifurcation présente dans la direction de la progression sur la route qu'un corps mobile parcourt ; et un moyen de commande d'affichage qui affiche sur un moyen d'affichage une image guide contenant des informations indiquant la présence de chacune de la pluralité de routes de bifurcation indiquées par les panneaux routiers réellement présents sur la route sur laquelle le corps mobile circule, et des informations d'encombrement et/ou des informations de restriction de circulation correspondant à chacune de la pluralité de routes de bifurcation, qui sont indiquées par les panneaux routiers et obtenues par le moyen d'acquisition d'informations de circulation. Le résultat est que les informations d'encombrement et les informations de restriction de circulation peuvent être aisément saisies par un utilisateur et qu'une zone d'affichage contenue dans l'affichage tête haute peut être efficacement utilisée.
