  • Patent Document 1 discloses a HUD that can improve safety at intersections.
  • the HUD in Patent Document 1 projects an image showing an overhead view of the intersection onto the image projection unit at a first timing when the vehicle approaches the intersection to a predetermined distance, and projects an image showing other vehicles superimposed on the actual scene onto the image projection unit at a second timing when the vehicle approaches the intersection even closer than the first timing.
  • the HUD in Patent Document 1 is said to be able to recognize other vehicles earlier and further improve safety at intersections.
  • the display formats of driving assistance display devices generally include real images of the traffic environment around the vehicle and icon images that show the traffic environment around the vehicle in icon form.
  • Real images allow the driver to grasp the situation around the vehicle more accurately, based on reality.

This places a burden on the driver, so icon images that show a schematic representation of mainly the information necessary for driving are widely used.

For example, when approaching an intersection where there are multiple other vehicles on the approaching road, if the other vehicles are displayed as icon images, multiple moving icon images are displayed, which is difficult for the driver to judge and irritating. Also, in poor visibility environments such as at night or in thick fog, it is difficult for icon images to correspond to the actual traffic environment, which may cause stress for the driver.

Abstract

L'invention concerne un dispositif d'affichage d'aide à la conduite qui permet l'affichage d'informations de voie de circulation correspondant à un changement de l'environnement de circulation dans une région d'intersection avec une autre voie de circulation, sous une forme qui pouvant être reconnue visuellement facilement par un conducteur, ainsi qu'un procédé d'affichage d'aide à la conduite. Ce dispositif d'affichage d'aide à la conduite comprend une unité d'affichage (20) qui présente deux modes d'affichage, parmi un premier mode d'affichage dans lequel des objets sont affichés dans une image simplifiée dans laquelle des objets sont schématisés, et un second mode d'affichage dans lequel les objets sont affichés dans une image détaillée utilisant des images réelles, et qui est caractérisée par la commutation entre le premier mode d'affichage et le second mode d'affichage dans un cas où une condition qui est définie à l'avance est satisfaite.
