Abstract

The head-up instrument display system for motor vehicles is for use with vehicle-mounted radar anti-collision equipment. The display of data uses a series of LEDs mounted near the windscreen so that light is reflected from the windscreen to the eyes of the vehicle driver without distracting his attention from the road ahead. The LED matrix can be arranged so that certain patterns or colours indicate the range and bearing of obstructions ahead of the vehicle as detected by the radar. The information is first stored in a register before being passed to the display. The diode matrix (1)(2) may be mounted in a suitable position on top of the dashboard (5) so that the display appears in the driver's line of vision through reflection.

neue Patentansprüche 1-5 "Anzeigevorrichtung" Die Erfindung betrifft eine Vorrichtung zur optischen Anzeige von Hindernissen vor Kraftfahrzeugen, welche mittels in Fahrtrichtung abgestrahlter und reflektierter Energie erfaßt und in einer Speichermatrix aufgezeichnet werden. Als Einrichtung zur Abstrahlung und zum Empfang der reflektierten Energie kommt in erster Linie ein Radargerät in Betracht.new claims 1-5 "display device" The invention relates to a device for the visual display of obstacles in front of motor vehicles, which detected by means of radiated and reflected energy in the direction of travel and in one Memory matrix are recorded. As a device for emission and reception of the reflected energy is primarily a radar device.

Zur Verbesserung der Verkehrssicherheit, des Verkehrsflusses und der Verkehrsleistung werden elektronische Hilfen gesucht, die auch bei schlechten Sichtverhältnissen vor den Kraftfahrzeugen auftauchende Hindernisse frühzeitig erkennbar machen, damit das Kraftfahrzeug rechtzeitig zum Halten gebracht werden kann.To improve road safety, traffic flow and the Electronic aids are sought, even when visibility is poor Make obstacles appearing in front of the motor vehicle recognizable at an early stage so that the motor vehicle can be brought to a stop in time.

Die Erfindung befaßt sich mit einer optischen Anzeigevorrichtung für ein solches Abstandswarngerät, mit der vor dem Fahrzeug auftauchende Hindernisse, die vom Radar erfaßt worden sind, dem Fahrzeugführer signalisiert werden.The invention relates to an optical display device for such a distance warning device, with which obstacles appearing in front of the vehicle, which have been detected by the radar are signaled to the vehicle driver.

Der Erfindung liegt die Aufgabe zugrunde, eine optische Anzeigevorrichtung für in Kraftfahrzeuge einzubauende Abstandswarngeräte anzugeben, die den Kraftfahrzeugführer auch bei schlechten Sichtverhältnissen frühzeitig auf Gefahrenpunkte aufmerksam macht, ohne daß seine Aufmerksamkeit vom übrigen Verkehrsgeschehen abgelenkt wird. Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß im Blickfeld des Fahrzeugführers ein den Inhalt der Speichermatrix signalisierende IJeuchtdiodenmatrix angeordnet ist und daß jede Leuchtdiode einem bestimmten Entfernungs- und Winkelbereich des vom Energiestrahl erfaßten Sektors zugeordnet ist.The invention is based on the object of an optical display device for distance warning devices to be installed in motor vehicles, which the motor vehicle driver alert you to danger points early on, even in poor visibility makes without his attention being distracted from the rest of the traffic. This object is achieved according to the invention in that in the field of vision of the vehicle driver a light emitting diode matrix signaling the content of the memory matrix is arranged is and that each light emitting diode has a certain distance and angle range of the is assigned to the sector covered by the energy beam.

Die Halbleiterleuchtdioden der Leuchtdiodenmatrix können gemäß der Erfindung zwischen den Schichten der Windschutzscheibe des Kraftfahrzeugs angebracht und entsprechend dem Inhalt der Speichermatrix ansteuerbar sein. Die Halbleiterleuchtdioden können zwischen den Schichten der Windschutzscheibe aufgedampft sein. Die Leuchtdiodenmatrix kann nach einem anderen Gedanken der Erfindung unterhalb der Windschutzscheibe auf der Oberseite des Armaturenbretts angeordnet sein und an der Windschutzscheibe in das Blickfeld des Fahrzeugführers gespiegelt werden.The semiconductor light-emitting diodes of the light-emitting diode matrix can according to FIG Invention applied between the layers of the windshield of the motor vehicle and be controllable according to the content of the memory matrix. The semiconductor light emitting diodes may be vapor deposited between the layers of the windshield. The light emitting diode matrix can according to another idea of the invention below the windshield the top of the dashboard and attached to the windshield in the driver's field of vision can be mirrored.

Die Leuchtdiodenmatrix kann auch neben den anderen Instrumenten in das Armaturenbrett eingebaut sein.The LED matrix can also be used in addition to the other instruments in the dashboard must be installed.

Die erfindungsgemäße Anzeigevorrichtung signalisiert Gefahrenpunkte, die sich vor dem Fahrzeug auf der Fahrbahn befinden, unmittelbar im Gesichtsfeld des Kraftfahrzeugführers, ohne aber dessen Sicht zu behindern. Durch die Wahl der Leuchtdioden kann deren Leuchten eine der Einstufung des Gefahrenmoments entsprechende Farbe gegeben werden. Beispielsweise können Reflekticnsberge, die bei der Reflektion der abgestrahlten Energie an relevanten Hindernissen entstehen, durch rotes und freies Gelände durch gar'indes Licht angezeigt werden. Die Ausführungsform, bei der die Leuchtdiodenmatrix auf der Oberseite des Armaturenbretts angebracht und über die Windschutzscheibe in das Gesichtsfeld des Fahrzeugführers gespiegelt wird, bietet eine besonders einfache Anpassungsmöglichkeit für verschiedene Sitzstellungen und Fahrer.The display device according to the invention signals danger points, that are in front of the vehicle on the road, directly in the field of vision of the motor vehicle driver, but without obstructing his view. By choosing the Light-emitting diodes can light up according to the classification of the moment of danger Color to be given. For example, reflective mountains can occur during reflection of the radiated energy at relevant obstacles arise, through red and clear terrain can be indicated by a gar'indes light. The embodiment at which the LED matrix attached to the top of the dashboard and is reflected via the windshield into the driver's field of vision, offers a particularly simple adjustment option for different sitting positions and driver.

Die Zeichnung zeigt eine Ausführung der Erfindung.The drawing shows an embodiment of the invention.

Auf dem Armaturenbrett 5 eines Kraftfahrzeugs 4 ist die Beuchtdiodenmatrix 2 außerhalb des direkten Blickfeldes des Fahrers angeordnet. An der Windschutzscheibe 3 wird es in das Gesichtsfeld des Fahrzeugführers eingspiegelt, der ein Aufleuchten der Dioden 1 ohne Miihe und ohne Beeinträchtigung seiner Aufmerksamkeit erkennen läßt. Die Sicht des Fahrers wird nicht behindert. LeerseiteThe light diode matrix is on the dashboard 5 of a motor vehicle 4 2 arranged outside the driver's direct field of vision. On the windshield 3 it is reflected in the driver's field of vision, which lights up of the diodes 1 without difficulty and without impairing his attention leaves. The driver's view is not obstructed. Blank page
