Abstract
Description
Die Erfindung betrifft eine Beleuchtungsvorrichtung für ein Fahrzeug gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lighting device for a vehicle according to the preamble of claim 1.
Gerade bei Dunkelheit ist es für einen ortsunkundigen Fahrer oft schwer, die Beschilderung an oder über einer Straße oder andere verkehrsrelevante Objekte rechtzeitig zu erkennen bzw. deren Informationen aufzunehmen.Especially in the dark it is often difficult for a driver unfamiliar with the location Signage on or over a street or other traffic-related Recognize objects in good time or record their information.
Das Problem tritt verstärkt bei höheren Geschwindigkeiten auf, da dann die Reaktions- und Erfassungszeit des Fahrers kürzer ist. Besonders wenn die normale Fahrzeugbeleuchtung ein Objekt in der Dunkelheit nicht mehr er reicht, wie dies beispielsweise bei Beschilderungen an Fahrbahnbrücken oder bei sonstigen in erhöhter Position angeordneten Schildern und Objek ten der Fall ist, kann ein Fahrer die für ihn gedachte Information nicht mehr aufnehmen.The problem becomes more pronounced at higher speeds because then the Response and detection time of the driver is shorter. Especially when the normal vehicle lighting no longer an object in the dark is sufficient, as is the case, for example, with signs on road bridges or with other signs and objects arranged in an elevated position If this is the case, a driver can no longer use the information intended for him take up.
Aufgabe der Erfindung ist es daher, eine Vorrichtung zur ausreichenden Sichtbarmachung von Objekten, insbesondere Beschilderungen, auch bei Dunkelheit anzugeben. The object of the invention is therefore to provide a device for sufficient Visualization of objects, especially signage, also at Indicate darkness.
Diese Aufgabe wird durch die im Anspruch 1 genannten Merkmale gelöst.This object is achieved by the features mentioned in claim 1.
Demgemäß aktiviert eine Steuereinheit eine Lichtquelle dann, wenn ein zu beleuchtendes Objekt kassiert wird. Ferner richtet die Steuereinheit den von einer Lichtquelle erzeugten Lichtstrahl auf das zu beleuchtende Objekt aus. Dazu werden die Daten aus der Datenbasis, welche zumindest Straßen- und/oder Objektdaten enthalten sowie die Fahrzeugposition und Fahrtrich tungsdaten ausgewertet. Entsprechend der darin enthaltenen Information reagiert die Steuereinheit.Accordingly, a control unit activates a light source when one is closed illuminating object is collected. Furthermore, the control unit directs the a light source generated light beam on the object to be illuminated. For this purpose, the data from the database, which are at least street and / or Contain object data as well as the vehicle position and driving lane evaluated. According to the information contained therein the control unit reacts.
Durch die erfindungsgemäße Beleuchtungsvorrichtung ist sichergestellt, daß bei Dunkelheit ansonsten nicht erkennbare Objekte, wie beispielsweise er höht angeordnete Hinweisschilder, vom Fahrer aufgenommen werden kön nen. Ferner wird die Aufmerksamkeit des Fahrer durch den Lichtstrahl in die Richtung des zu erfassenden Objektes gelenkt, so daß er sich auf diese bestimmte Stelle konzentrieren kann. Ferner ist die Infarmationserfassungs zeit für den Fahrer größer, so daß er auch bei größerer Geschwindigkeit eine Information länger und besser aufnehmen kann.The lighting device according to the invention ensures that objects that are otherwise not recognizable in the dark, such as him high-level signs that can be picked up by the driver nen. Furthermore, the driver's attention is drawn by the light beam into the Directed the direction of the object to be detected, so that it is on this can focus on a specific spot. Furthermore, the information collection is time for the driver to be larger so that he can drive at higher speeds can hold information longer and better.
Eine vorteilhafte Ausführung der Erfindung ist dadurch gekennzeichnet, daß der Lichtstrahl dem Objekt beim Passieren nachgeführt wird. Der erzeugte Lichtkegel hat nämlich immer nur eine bestimmte Größe, so daß bei einem schnellen Passieren das zu beleuchtende Objekt trotz der zusätzlichen Be leuchtung nicht allzulange sichtbar bleibt. Durch die Nachführung des Licht strahls ist der Zeitraum, in dem die Information aufgenommen werden kann, länger.An advantageous embodiment of the invention is characterized in that the light beam tracks the object as it passes. The generated one Cone of light has only a certain size, so that one quickly pass the object to be illuminated despite the additional lighting lighting does not remain visible for too long. By tracking the light is the period in which the information can be recorded, longer.
Ferner ist es von Vorteil, wenn die Lichtquelle bereits vor Erreichen eines zu beleuchtenden Objektes und/oder einige Zeit nach Passieren des Objektes aktiviert ist. Diese Maßnahme trägt der Tatsache Rechnung, daß zum einen die Fahrzeugposition eines Fahrzeugs gerade bei größeren Geschwindigkei ten nur in bestimmten Ungenauigkeitsbereichen angegeben werden kann. Es ist jedoch zu vermeiden, daß die Lichtquelle bereits vor Erreichen des Objektes wieder abgeschaltet bzw. erst nach Erreichen des Objektes akti viert wird.Furthermore, it is advantageous if the light source is already closed before reaching one illuminating object and / or some time after passing the object is activated. This measure takes account of the fact that, on the one hand the vehicle position of a vehicle, especially at higher speeds can only be specified in certain areas of inaccuracy. However, it is to be avoided that the light source is reached before the Object switched off again or activated only after reaching the object fourth.
Die Daten der Datenbasis können vorzugsweise von einer Straßendatenba sis, insbesondere von einer digitalen Straßenkarte, und/oder von einem GPS-System (global positioning system, satellitengestützten System) und/oder von einem Fahrzeug-Kommunikationssystem oder einem Fahr zeug-Sensarsystem und/oder einer speziellen Datenbank stammen. We sentlich ist lediglich, daß Informationen über die Straße bzw. ein zu erfas sendes Objekt vorliegen.The data of the database can preferably be from a road database sis, in particular from a digital road map, and / or from one GPS system (global positioning system, satellite-based system) and / or from a vehicle communication system or a vehicle tool sensor system and / or a special database. We It is only essential that information about the street or a to be acquired sending object.
Die vorliegende Erfindung wird anhand eines Beispiels mit Bezug auf die beiliegende Zeichnung näher erläutert. In der einzigen Zeichnung ist eine perspektivische Ansicht eines nur umrißhaft dargestellten Fahrzeugs 8 (ohne Reifen) gezeigt.The present invention is explained in more detail using an example with reference to the accompanying drawings. The only drawing shows a perspective view of a vehicle 8 (without tires) which is only shown in outline.
Im Dachbereich des Fahrzeugs 8 ist eine längliche, im wesentlichen quer zur Fahrtrichtung angeordnete Lichtquelle 10 vorgesehen. Diese Lichtquelle 10 ist ausrichtbar angeordnet und von einer (nicht dargestellten) Stelleinheit beaufschlagt. Diese Stelleinheit wird von einer Steuereinheit (ebenfalls nicht dargestellt) mit Steuersignalen versorgt, und entsprechend diesen Steuersi gnalen wird die Lichtquelle 10 ausgerichtet.In the roof area of the vehicle 8 , an elongated light source 10 is provided which is arranged essentially transversely to the direction of travel. This light source 10 is arranged such that it can be aligned and acted upon by an actuating unit (not shown). This actuating unit is supplied with control signals by a control unit (likewise not shown), and the light source 10 is aligned in accordance with these control signals.
Die Steuereinheit wertet die Fahrzeugposition sowie die Fahrtrichtung und auch Objektdaten und/oder Straßendaten aus und stellt unter Berücksichti gung dieser Informationen fest, wann und in welcher Weise die Lichtquelle 10 aktiviert bzw. ausgerichtet sein muß, um ein zu beleuchtendes Objekt anzustrahlen. The control unit evaluates the vehicle position and the direction of travel and also object data and / or road data and, taking this information into account, determines when and in what way the light source 10 must be activated or aligned in order to illuminate an object to be illuminated.
Kommt ein solches Objekt in den Erfassungsbereich des von der Lichtquelle erzeugten Lichtstrahls 12, so wird die Lichtquelle aktiviert, und der auf das Objekt ausgerichtete Lichtstrahl erleuchtet dieses.If such an object comes into the detection range of the light beam 12 generated by the light source, the light source is activated and the light beam aligned with the object illuminates it.
Soweit es im Stellbereich der Lichtquelle 10 möglich ist, wird der Lichtstrahl 12 beim Passieren des Objektes diesem nachgeführt. Zur Ausschaltung von Positionsunsicherheiten des Fahrzeugs wird die Lichtquelle 10 eingeschal tet, bevor der Erfassungsbereich erreicht ist. Damit bekommt der Fahrer Aufschluß, in welcher Blickrichtung eine Objektinfarmation kommen wird. Die Lichtquelle wird dann kurze Zeit nach Passieren des Objektes wieder deak tiviert.Insofar as it is possible in the adjustment range of the light source 10 , the light beam 12 is tracked when it passes the object. To eliminate positional uncertainties of the vehicle, the light source 10 is switched on before the detection range is reached. This gives the driver information about the direction in which an object information will come. The light source is then deactivated again a short time after passing the object.
Der Lichtkegel der Lichtquelle 10 ist vorzugsweise so ausgebildet, daß auch größere Beschilderungen im Autobahnbereich nach gut ausgeleuchtet wer den können.The light cone of the light source 10 is preferably designed so that even larger signage in the freeway area can be well lit who can.
Natürlich kann die Lichtquelle 10 alternativ zum vorliegenden Ausführungs beispiel auch in anderen Bereichen des Fahrzeugs plaziert werden.Of course, as an alternative to the present embodiment, the light source 10 can also be placed in other areas of the vehicle, for example.
Wesentlich für die Erfindung ist, daß ein Objekt bei Dunkelheit zu beleuch ten ist, so daß der Fahrer die von diesem Objekt ausgehenden Informatio nen ohne Schwierigkeiten aufnehmen kann.It is essential for the invention that an object be illuminated in the dark ten is so that the driver the information from this object can record without difficulty.
