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 betriffteine Vorrichtung zur optischen Anzeige von Hindernissen vor Kraftfahrzeugen, welchemittels in Fahrtrichtung abgestrahlter und reflektierter Energie erfaßt und in einerSpeichermatrix aufgezeichnet werden. Als Einrichtung zur Abstrahlung und zum Empfangder reflektierten Energie kommt in erster Linie ein Radargerät in Betracht.new claims 1-5 "display device" The invention relates toa device for the visual display of obstacles in front of motor vehicles, whichdetected by means of radiated and reflected energy in the direction of travel and in oneMemory matrix are recorded. As a device for emission and receptionof the reflected energy is primarily a radar device.

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

Die Erfindung befaßt sich mit einer optischen Anzeigevorrichtung fürein 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 forsuch 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 Anzeigevorrichtungfür in Kraftfahrzeuge einzubauende Abstandswarngeräte anzugeben, die den Kraftfahrzeugführerauch bei schlechten Sichtverhältnissen frühzeitig auf Gefahrenpunkte aufmerksammacht, ohne daß seine Aufmerksamkeit vom übrigen Verkehrsgeschehen abgelenkt wird.Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß im Blickfeld des Fahrzeugführersein den Inhalt der Speichermatrix signalisierende IJeuchtdiodenmatrix angeordnetist und daß jede Leuchtdiode einem bestimmten Entfernungs- und Winkelbereich desvom Energiestrahl erfaßten Sektors zugeordnet ist.The invention is based on the object of an optical display devicefor distance warning devices to be installed in motor vehicles, which the motor vehicle driveralert you to danger points early on, even in poor visibilitymakes 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 drivera light emitting diode matrix signaling the content of the memory matrix is arrangedis and that each light emitting diode has a certain distance and angle range of theis assigned to the sector covered by the energy beam.

Die Halbleiterleuchtdioden der Leuchtdiodenmatrix können gemäß derErfindung zwischen den Schichten der Windschutzscheibe des Kraftfahrzeugs angebrachtund entsprechend dem Inhalt der Speichermatrix ansteuerbar sein. Die Halbleiterleuchtdiodenkönnen zwischen den Schichten der Windschutzscheibe aufgedampft sein. Die Leuchtdiodenmatrixkann nach einem anderen Gedanken der Erfindung unterhalb der Windschutzscheibe aufder Oberseite des Armaturenbretts angeordnet sein und an der Windschutzscheibe indas Blickfeld des Fahrzeugführers gespiegelt werden.The semiconductor light-emitting diodes of the light-emitting diode matrix can according to FIGInvention applied between the layers of the windshield of the motor vehicleand be controllable according to the content of the memory matrix. The semiconductor light emitting diodesmay be vapor deposited between the layers of the windshield. The light emitting diode matrixcan according to another idea of the invention below the windshieldthe top of the dashboard and attached to the windshield inthe driver's field of vision can be mirrored.

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

Die erfindungsgemäße Anzeigevorrichtung signalisiert Gefahrenpunkte,die sich vor dem Fahrzeug auf der Fahrbahn befinden, unmittelbar im Gesichtsfelddes Kraftfahrzeugführers, ohne aber dessen Sicht zu behindern. Durch die Wahl derLeuchtdioden kann deren Leuchten eine der Einstufung des Gefahrenmoments entsprechendeFarbe gegeben werden. Beispielsweise können Reflekticnsberge, die bei der Reflektionder abgestrahlten Energie an relevanten Hindernissen entstehen, durch rotes undfreies Gelände durch gar'indes Licht angezeigt werden. Die Ausführungsform, beider die Leuchtdiodenmatrix auf der Oberseite des Armaturenbretts angebracht undüber die Windschutzscheibe in das Gesichtsfeld des Fahrzeugführers gespiegelt wird,bietet eine besonders einfache Anpassungsmöglichkeit für verschiedene Sitzstellungenund 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 visionof the motor vehicle driver, but without obstructing his view. By choosing theLight-emitting diodes can light up according to the classification of the moment of dangerColor to be given. For example, reflective mountains can occur during reflectionof the radiated energy at relevant obstacles arise, through red andclear terrain can be indicated by a gar'indes light. The embodiment atwhich the LED matrix attached to the top of the dashboard andis reflected via the windshield into the driver's field of vision,offers a particularly simple adjustment option for different sitting positionsand 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 Beuchtdiodenmatrix2 außerhalb des direkten Blickfeldes des Fahrers angeordnet. An der Windschutzscheibe3 wird es in das Gesichtsfeld des Fahrzeugführers eingspiegelt, der ein Aufleuchtender Dioden 1 ohne Miihe und ohne Beeinträchtigung seiner Aufmerksamkeit erkennenläßt. Die Sicht des Fahrers wird nicht behindert.LeerseiteThe light diode matrix is on the dashboard 5 of a motor vehicle 42 arranged outside the driver's direct field of vision. On the windshield3 it is reflected in the driver's field of vision, which lights upof the diodes 1 without difficulty and without impairing his attentionleaves. The driver's view is not obstructed.Blank page
