Abstract

L'invention concerne un affichage tête haute (2) qui comprend une unité de source de lumière (4) et un combinateur (9). Un dispositif de commande (55) de l'unité de source de lumière (4) permet l'affichage des images symboliques des installations sous la forme d'image virtuelles (Iv) à des positions correspondantes des installations sur le combinateur (9) de telle sorte que les images symboliques soient superposées sur une scène réelle. A cet instant, à l'exception des installation situées à l'intérieur d'une zone cible d'affichage (AT) qui comprend une zone déterminée dans la direction de déplacement d'un véhicule (Ve) et où se trouvent les installations qui doivent être affichées, le dispositif de commande (55) limite l'affichage des images symboliques des installations qui se trouvent à l'intérieur d'une zone à accès restreint (AR) déterminée dans une direction éloignée de la direction de déplacement.
