Definitions

  • the object of the invention is therefore to provide a device for displaying lateral and rear surrounding images of a vehicle, which does not unnecessarily increase the width of the vehicle and does not unnecessarily increase fuel consumption.
  • the device has an electronic image recording device, that it has an electronic image generating device, that it has an optical image enlarging device, that that can be displayed by the electronic image capturing device after capturing the information on the electronic image generating device, and with the image enlarging device can be enlarged and projected onto a first mirror inside the vehicle, so that a driver of the vehicle can perceive the information displayed with the electronic image generation device as a virtual image.
  • This ensures that no outside the mirror is required and thus the width of the vehicle can be significantly reduced, since the electronic image capture device can be integrated into the outer contour of the motor vehicle and, if at all, only insignificantly broadens the motor vehicle.
  • the representation of the image information comes very close to the previously used optical rear-view mirror arranged outside the vehicle.
  • the fact that the mirror or mirrors are arranged in the area of an A-pillar within the vehicle means that a driver does not have to get used to it, since he would also be looking for a rear-view mirror arranged outside the vehicle in this area.
  • the fact that the image generation device and part of the image enlargement device are combined to form an imaging unit means that a compact structure can be achieved. Because the imaging unit is arranged in the dashboard, a compact, inconspicuous structure can be achieved.
  • the imaging unit is arranged in the roof area of the vehicle, this unit can be accommodated particularly well in motor vehicles and commercial vehicles because of the space available there and no installation space is required in the dashboard. Because the imaging unit can be used to generate a plurality of partial images which can be projected onto a first mirror in each case, it is possible to provide a plurality of first mirrors with image information using only a single imaging unit. In this way, for example, a left, a middle and a right mirror can be supplied and thus give a familiar impression to a driver. It is possible here for the partial images to partially overlap, so that parts of the image information can be displayed simultaneously on two different first mirrors. If there are several imaging units, they can be very compact.
  • the electronic imaging device can be a liquid crystal talldisplay (LCD), digital mirror device (DMD), a liquid crystal on silicon (LCOS) or an electron tube.

  • electron tube an electron tube.
  • the first three imaging devices mentioned can be constructed very compactly.
  • Fig. 2 shows a second embodiment
  • Fig. 3 shows a third embodiment of the invention.

Furthermore, the imaging unit 1 has a second mirror 4, which is part of the magnification device. The first mirror is also arched and is therefore part of the magnification device. Light rays S of the image generated by means of the TFT display 3a are reflected into the eye E of a driver via the second mirror and the first mirror. As a result, he can perceive the image shown on the transmissive TFT display 3a as a virtual image P.

  • the beam path is selected such that half of the image shown on the transmissive TFT display is perceptible on the first mirror 6a or 6b. It is also possible to design the beam path in such a way that parts of the image shown on the transmissive TFT display can be displayed simultaneously on the first mirror 6a and the first mirror ⁇ b.

Abstract

La présente invention concerne un dispositif pour représenter des images de l'environnement latéral et arrière d'un véhicule. Selon l'invention: le dispositif comprend un système électronique d'acquisition d'image, un système électronique de production d'image (3, 7) et un système optique de grossissement d'image (2, 4, 6a, 6b, 8a, 8b); les informations détectées par le système électronique d'acquisition d'image, peuvent être représentées sur le système électronique de production d'image (3, 7), grossies par le système de grossissement d'image (2, 4, 6a, 6b, 8a, 8b), et projetées sur un premier miroir du véhicule de sorte que les informations représentées par le système de production d'image (3, 7) apparaissent au conducteur du véhicule sous la forme d'une image virtuelle (P, P1, P2).
