Definitions

  • the coating cost increases as the area of the glass increases.
  • the antireflection layer provided on the outer surface of the vehicle deteriorates due to the influence of rain and wind, etc., and does not exert the effect of suppressing the reflection of the injection port with the passage of time.
  • the specular reflection generation region D1 is the intersection of the specularly reflected light from the upper and lower ends of the eyebox EB toward the upper and lower ends of the windshield WS and the specularly reflected light reflected by the windshield WS and the upper surface of the dashboard D. Is the area within the specific intersection, where is defined as the "specific intersection”. That is, it can be said that the specular reflection generation region D1 is a region inside the outer shell generated by connecting the specific intersections. Further, as shown in FIG. 1, for example, the specular reflection generation region D1 is paraphrased as an region between the portion of the dashboard D that abuts on the windshield WS and the specific intersection closest to the driver in a cross-sectional view. You can also do it.
  • the upper surface of the dashboard D referred to here is a surface of the outer surface of the dashboard D located in a direction opposite to the vertical direction.
  • the imaging unit F acquires the position information of the occupant's eyes when the occupant's posture changes due to the occupant tilting the seat of the vehicle V toward the rear of the vehicle, and obtains the position information of the occupant's eyes on the dashboard D. It is used to calculate the change in the specular reflection generation region D1.
  • the effect of the above-mentioned first embodiment can be obtained also by this embodiment. Further, the specular reflection generation region D1 fluctuates due to the change in the posture of the occupant, and even if the projection lens 21 of the projector 2 is located in this region, the windshield display device S2 can move the projector 2.
  • the control unit 4 has a correction unit. May be.
  • the correction unit executes control for maintaining the display position and size of the image before and after the movement of the projector 2.

Abstract

Selon la présente invention, un dispositif d'affichage de pare-brise, qui fait en sorte qu'un occupant dans un corps en mouvement (V) reconnaisse visuellement une image à un emplacement d'un pare-brise (WS), comporte: un écran transparent (1) qui est disposé en recouvrement avec le pare-brise; et un projecteur (2) qui projette une lumière d'image sur l'écran transparent. Le projecteur est doté d'une lentille (21) de projection et est disposé de telle façon qu'au moins la lentille de projection soit située dans une région d'un tableau de bord (D) du corps en mouvement, la région étant différente d'une région de génération de réflexion régulière (D1). Lorsqu'on suppose la présence d'une lumière de réflexion régulière qui est obtenue suite à une réflexion régulière, par le pare-brise, d'une lumière linéaire se propageant des extrémités verticales supérieure et inférieure d'un rectangle oculaire (EB) de l'occupant vers les extrémités verticales supérieure et inférieure du tableau de bord, la région de génération de réflexion régulière est une région située à l'intérieur d'un contour formé en reliant les intersections entre le tableau de bord et la lumière de réflexion régulière.
