  • the imaging position of the virtual image V2 of the left rear image is not on the extension line from the left end surface of the vehicle 1, the driver corrects the sense by comparing with the virtual image V3 of the pair of the right rear image. Therefore, even for the virtual image V2 of the left rear image, it is possible to reduce a sense of incongruity due to a deviation between the imaging position and the imaging position.

Abstract

L'invention concerne un dispositif d'affichage de véhicule qui permet une reconnaissance intuitive d'une direction à partir de laquelle une image d'affichage est obtenue par imagerie sans nécessiter un grand déplacement de point de vue. Un dispositif d'affichage de véhicule (1000) est pourvu des éléments de réflexion (513, 523, 533) pour refléter une lumière d'affichage (L1, L2) vers un observateur de façon à permettre une reconnaissance visuelle d'une image virtuelle d'une image d'affichage. L'image d'affichage comprend au moins une image d'aide à la conduite comprenant des informations de véhicule ou des informations de navigation, une image de l'arrière gauche obtenue par imagerie d'une zone à la gauche et à l'arrière d'un véhicule (1), et une image de l'arrière droit obtenue par imagerie d'une zone à la droite et à l'arrière du véhicule (1). Une image virtuelle (V1) de l'image d'aide à la conduite est entièrement incluse dans un angle de champ de vision effectif dans une direction horizontale. Une image virtuelle (V2) de l'image de l'arrière gauche est positionnée sur le côté gauche de l'image virtuelle (V1) de l'image d'aide à la conduite, au moins une partie de l'image virtuelle (V2) étant incluse dans l'angle de champ de vision effectif dans la direction horizontale. Une image virtuelle (V3) de l'image de l'arrière droit est positionnée sur le côté droit de l'image virtuelle (V1) de l'image d'aide à la conduite, au moins une partie de l'image virtuelle (V3) étant incluse dans l'angle de champ de vision effectif dans la direction horizontale.
