Definitions

  • the invention relates to a glare protection device for a motor vehicle according to the preamble of claim 1 and a method for controlling a glare protection device for a motor vehicle.
  • a drivable filter disk especially for motor vehicles, which has a plurality of predetermined liquid crystal regions, with the help of which larger sections of the filter disk can be darkened. This reduces glare, but at the same time considerably limits the driver's field of vision.
  • a screen element which is arranged in the area of the windshield of the motor vehicle and covers a certain area of the driver's field of vision.
  • the screen element is moved mechanically.
  • Such mechanical devices have several disadvantages. On the one hand, their mechanical control is very complex. On the other hand the degree of darkening or the degree of transmission of such a screen element cannot be varied. Opaque screen elements have a degree of darkening of 100% (degree of transmission 0%). In addition, the size of the blend element is fixed and cannot be adapted to the apparent size of the dazzling object. As a result, either the glare object is not completely darkened, ie a residual glare remains, or the glare element covers the glare object by far and thereby impairs the driver's field of vision, which is also undesirable and is perceived as disturbing. In general, mechanical devices react with certain time delays, so that a quick reaction to sudden light reflections is also not possible.
  • the object of the invention is to provide an anti-glare device for a motor vehicle and a method for controlling an anti-glare device for a motor vehicle, which avoid the disadvantages specified above, which in particular allow delay-free masking of the glare object, which enable adaptation to the glare object and which are simple and can be produced and carried out inexpensively.
  • the essential idea of the invention is to design a filter plate that can be uncoupled, in which case individual matrix elements of the filter disc can be uncoupled.
  • the filter disk is controlled via a control unit, which is connected to sensors for detecting a glare object and to a camera for detecting the current eye position of a motor vehicle occupant.
  • the point of intersection (passage point) of the light path “glare object” “eye position vehicle occupant” with the filter disk is determined in the control unit, and this area of the filter disk is darkened by appropriate activation of the filter disk.

  • FIG. 1 schematically shows an anti-glare device 1 according to the invention based on a view of the front window area of a motor vehicle.

In the interior 52, two motor vehicle occupants, a driver and a passenger, are indicated schematically on the front seats by their corresponding eye positions 40 and 42, respectively The eye position 40 or 42 is recorded by a camera 24, which is also arranged in the interior 52. The camera 24 is connected to the control unit 20 via a connecting line 25c.

The important thing here is that the two sensors 22a, 22b each provide a clear view in the direction of the glare object 30.

  • the size of the darkened area 36 thus becomes just so large that the shadow cast covers the driver's eye position 40. Because of the adapted small size of the darkened area 36, the driver's field of vision is only limited in certain areas, specifically in the area that would lead to glare

  • Glare objects 30 of lower intensity are therefore darkened to a lesser extent for the driver. However, this also affects his field of vision less, which in turn increases traffic safety.
  • a darkened area 36 can be easily generated on a filter disk 10 without delay.
  • the area 36 follows the movement of the glare object 30 and adapts to the glare object 30 in terms of its size and its darkening behavior. As a result, the effects on the driver are considerably reduced and the traffic safety is thus increased.

Abstract

L'invention concerne un dispositif anti-éblouissement destiné à un véhicule automobile, comportant une vitre filtrante qui peut s'obscurcir. Dans ce dispositif, une unité de commande (20) est reliée à des détecteurs (22a, 22b) pour détecter un objet éblouissant (30) et à une caméra (24) pour détecter la position (40, 42) des yeux d'un occupant du véhicule automobile. La vitre filtrante (10) conçue de manière matricielle comporte des éléments matriciels individuels (38) pouvant s'obscurcir. Ce dispositif permet de créer facilement et immédiatement sur une vitre filtrante (10) une zone obscurcie (36) qui suit le mouvement de l'objet éblouissant (30). La taille et les propriétés d'obscurcissement de cette zone s'adaptent à l'objet éblouissant (30). Ce dispositif permet de réduire considérablement les phénomènes d'éblouissement pour le conducteur et accroît ainsi la sécurité routière.
