Abstract

The range of vision of the driver (17) is extended by an IR sensitive camera (14) connected to a display device (16) which projects the image onto the windscreen. The driver sees simultaneously and uninterruptedly the areas served by the fog lamps (11) and the IR camera (14). For good superposition of the virtual and real images, the camera should be mounted close to the driver's eyes, e.g. on the internal rear-view mirror. Halogen lamp emission contains a sufficient IR component. USE/ADVANTAGE - IR vision system for car driver. Safety, esp. in fog, is enhanced without additional dazzle of oncoming drivers.

Eine andere Anzeigevorrichtung, die Anwendung in Kraftfahrzeugen findet, ist aus der DE-OS 38 22 222 bekannt, die eine Einrichtung für Head-up-Displays in Kraftfahrzeugen beschreibt. Ein Head-up-Dis­ play spiegelt bildhaft dargestellte Anzeigemuster in das Sichtfeld des Fahrers. Dabei werden auf einen Teil der Windschutzscheibe, der im Sichtfeld des Fahrers liegt, Meß- oder Warnsignale eingeblendet. Zur Überlagerung des virtuellen Bildes, das aus den Anzeigenele­ menten gebildet wird, mit dem tatsächlichen Bild der äußeren Land­ schaft ist beispielsweise ein teildurchlässiger Spiegel vorgesehen, wobei die Reflexion an der Windschutzscheibe ausgenutzt werden kann oder eine vor der Windschutzscheibe stehende zusätzliche Scheibe (Combiner) benutzt werden kann.Another display device for use in motor vehicles finds is known from DE-OS 38 22 222, which is a device for head-up displays in motor vehicles. A head-up dis play reflects pictorial display patterns in the field of vision of the driver. Do this on part of the windshield, the is in the driver's field of vision, measurement or warning signals are displayed. For overlaying the virtual image from the display element ment is formed with the actual image of the outer country for example, a partially transparent mirror is provided, the reflection on the windshield can be exploited or an additional pane in front of the windshield (Combiner) can be used.

Zeichnungdrawing

Eine erfindungsgemäße Vorrichtung zur Verbesserung der Sichtver­ hältnisse in einem Kraftfahrzeug ist in der Figur dargestellt.A device according to the invention for improving the sight Ratios in a motor vehicle is shown in the figure.

In der Figur ist ein Kraftfahrzeug 10 gezeigt, dessen Scheinwerfer und/oder Nebelscheinwerfer 11 den vor dem Fahrzeug 10 liegenden Sichtbereich 12 bestrahlen. Die Grenzen 13 der von den Scheinwerfern 11 ausgehenden Strahlung sind in der Figur strichliniert mit kurzen Strichen eingetragen. Die Strahlung der Scheinwerfer 11 enthält einen Infrarotstrahlungsanteil, der von einer im Fahrzeug 10 ange­ ordneten infrarotempfindlichen Kamera 14 erfaßt wird. Die Grenzen 15 der von der Kamera 14 erfaßten Strahlung sind in der Figur strich­ liniert mit langen Strichen eingetragen. Das von der Kamera 14 ab­ gegebene Bild ist einer Anzeigevorrichtung 16 zugeführt, die das Bild der Kamera 14 als virtuelles Bild dem Bild der äußeren Land­ schaft visuell überlagert.In the figure, a motor vehicle 10 is shown, the headlights and / or fog lights 11 of which illuminate the visible area 12 lying in front of the vehicle 10 . The limits 13 of the radiation emanating from the headlights 11 are shown in the figure by dashed lines with short dashes. The radiation of the headlights 11 contains an infrared radiation component which is detected by an infrared-sensitive camera 14 arranged in the vehicle 10 . The boundaries 15 of the radiation detected by the camera 14 are shown in the figure with dashed lines and long lines. The image given by the camera 14 is supplied to a display device 16 which visually overlays the image of the camera 14 as a virtual image of the image of the outer landscape.

Mit der erfindungsgemäßen Vorrichtung sieht der Fahrer 17 gleich­ zeitig und ununterbrochen den Sichtbereich 12 soweit wie möglich direkt mit der sichtbaren Strahlung und den entfernteren Straßen­ raum, der beispielsweise in Nebel gehüllt ist, mit Hilfe der von der Kamera 14 erfaßten Infrarotstrahlung. Die Auswertung der über­ lagerten Bilder erfolgt ausschließlich durch einen Fahrer 17, wobei keine weitere Signalverarbeitung nötig ist. With the device according to the invention, the driver 17 sees the viewing area 12 simultaneously and continuously as far as possible directly with the visible radiation and the more distant road space, which is, for example, enveloped in fog, with the help of the infrared radiation detected by the camera 14 . The overlaid images are evaluated exclusively by a driver 17 , no further signal processing being necessary.

Um eine gute Überlagerung des virtuellen Bildes mit dem tatsäch­ lichen Bild der äußeren Landschaft zu erhalten, sollte die Infrarot­ kamera 14 möglichst in Augennähe des Fahrers 17, beispielsweise bei einem Rückspiegel des Kraftfahrzeugs 10 angeordnet sein. Anderer­ seits sollte das optische System, das die Kamera 14 und die Anzeige­ vorrichtung 16 enthält, so ausgelegt sein, daß ein Betrachtungs­ winkel α der sichtbar gemachten Infrarotaufnahme der äußeren Land­ schaft dem Betrachtungswinkel β des direkt betrachteten Sichtbe - reichs 12 entsprechen. Weiterhin sollte die Darstellung der Infra­ rotaufnahme vor den Augen so weit entfernt sein, daß beim Betrachten keine Akkommodation nötig ist. Als Anzeigevorrichtung ist ein be­ kanntes Head-up-Display vorgesehen.In order to obtain a good overlay of the virtual image with the actual image of the outer landscape, the infrared camera 14 should be arranged as close as possible to the eyes of the driver 17 , for example in a rearview mirror of the motor vehicle 10 . On the other hand, the optical system, which contains the camera 14 and the display device 16 , should be designed such that a viewing angle α of the infrared image made visible of the outer landscape corresponds to the viewing angle β of the directly viewed viewing area 12 . Furthermore, the representation of the infrared image in front of the eyes should be so far away that no accommodation is necessary when viewing. A known head-up display is provided as a display device.

Der Infrarotstrahlungsanteil der derzeit verwendeten Glühlampen, gegebenenfalls mit Halogenzusatz, ist für die Bestrahlung des Sicht­ bereichs 12 ausreichend. Die in Zukunft gegebenenfalls vorgesehenen Entladungslampen weisen ein in Richtung auf kürzere Wellenlängen hin verschobenes Spektrum auf, so daß gegebenenfalls zusätzliche Infrarotstrahler erforderlich werden. Eine zusätzliche Blendung ent­ gegenkommender Fahrer von Kraftfahrzeugen tritt nicht auf.The infrared radiation component of the incandescent lamps currently used, possibly with halogen addition, is sufficient for irradiating the viewing area 12 . The discharge lamps which may be provided in the future have a spectrum which is shifted towards shorter wavelengths, so that additional infrared radiators may be required. There is no additional glare for oncoming drivers of motor vehicles.
