Abstract

L'invention concerne un système d'affichage pour un véhicule à moteur (11), selon lequel un dispositif d'imagerie (2) génère une information imagée qui est visualisée par un système optique (5) sous forme d'image (10) virtuelle dans le champ de vision du pilote (7) d'un véhicule à moteur (11). Selon l'invention, le système d'affichage représente l'image (10) virtuelle dans une zone située au-dessus du champ de vision (17) linéaire horizontal du pilote (7). Ainsi, l'image (10) virtuelle ne gêne pas la vue sur la circulation.
