Abstract
Description
Die Erfindung betrifft eine Anordnung zur Bildprojektion in einem Kraftfahrzeug, insbesondere zur Darstellung von Verkehrs- oder Statusinformationen mit mindestens einer, vorzugsweise an der Decke des Fahrzeuginnenraumes angeordneten, Projektionseinheit, umfassend eine Beleuchtungsoptik sowie ein verstellbares Linsensystem, wobei das von der Projektionseinheit ausgehende Bild auf eine für mindestens einen Fahrzeuginsassen einsehbare, im Fahrzeuginnenraum befindliche Projektionsfläche trifft.The The invention relates to an arrangement for image projection in a motor vehicle, in particular for displaying traffic or status information with at least one, preferably on the ceiling of the vehicle interior arranged, projection unit, comprising a lighting optics and an adjustable lens system, which by the projection unit outgoing picture on one for at least a vehicle occupants visible, located in the vehicle interior Projection surface meets.
Bekannt sind Anordnungen zur Darstellung von Bildinformationen in Kraftfahrzeugen, bei denen die Informationen über im Armaturenbrett angeordnete LCD Bildschirme dargestellt werden. Derartige Anordnungen haben den Nachteil, dass das Innenraumdesign des Fahrzeuges an die ebenen Konturen der Bildschirme angepasst werden muss. Ferner sind die Informationen meist im Sichtfeld aller Insassen, was teilweise als störend empfunden wird.Known are arrangements for displaying image information in motor vehicles, where the information is about displayed in the dashboard LCD screens are displayed. Such arrangements have the disadvantage that the interior design of the vehicle adapted to the flat contours of the screens must become. Furthermore, the information is mostly in the field of vision of all Inmates, which partly as annoying is felt.
Ferner
wird in
Aufgrund der meist aufwendigen Abbildungsoptik erfordert eine derartige virtuelle Abbildung einen großen Raumbedarf innerhalb des Armaturenbrettes, der meist nicht zur Verfügung steht.by virtue of the most elaborate imaging optics requires such a virtual Figure a big one Space inside the dashboard, which is usually not available.
Zur
Beseitigung wesentlicher Nachteile des dargelegten Standes der Technik
wird in
Mit einer derartigen Anordnung wird zwar gegenüber der Bereitstellung von Informationen auf LCD Bildschirmen oder der Lösung über die virtuelle Betrachtung von Bildern eine qualitativ hochwertige Darstellung realisiert, jedoch ist der Kostenaufwand, insbesondere dann, wenn die Informationen für verschiedene Fahrzeuginsassen sichtbar sein sollen, relativ hoch.With Although such an arrangement is compared to the provision of Information on LCD screens or the solution via virtual viewing realized a qualitatively high-quality representation of pictures, However, the cost, especially if the information for different Vehicle occupants should be visible, relatively high.
Ausgehend hiervon ist es Aufgabe der Erfindung; eine Anordnung zur Bildprojektion in einem Kraftfahrzeug dahingehend weiterzubilden, dass bei minimalem Aufwand eine gezielte Darstellung von Bildinformationen auf verschiedene Projektionsflächen im Fahrzeuginnenraum möglich wird.outgoing of this it is the object of the invention; an arrangement for image projection in a motor vehicle to the effect that with minimal Effort a targeted representation of image information to different projection possible in the vehicle interior becomes.
Diese Aufgabe wird durch eine Anordnung der eingangs beschriebenen Art dadurch gelöst, dass die Projektionseinheit in den drei Freiheitsgraden verschieb- sowie um die Verschiebeachsen schwenkbar angeordnet ist. Die Verstelleinheit des Linsensystems steht dabei vorteilhafterweise mit einem zum Zwecke der Bildschärfekorrektur bei Lageveränderung der Projektionseinheit und/oder bei Veränderung der Position oder Struktur der Projektionsfläche vorgesehenen elektronischen Kompensationsmodul in Verbindung.These Task is achieved by an arrangement of the type described above solved by that the projection unit in the three degrees of freedom displaced and pivotable about the displacement axes is arranged. The adjustment unit of the lens system is included advantageously with one for the purpose of image sharpness correction with change of position the projection unit and / or changing the position or structure the projection surface provided electronic compensation module in conjunction.
Bedingt durch verstellbare Anordnung der Projektionseinheit lassen sich verschiedene Projektionsflächen im Fahrzeuginnenraum zur Betrachtung von Bildinformationen auf einfache Art und Weise auswählen. Die Anpassung der Bildschärfe erfolgt dabei über das elektronische Kompensationsmodul durch Signalgebung zur Bewegungsänderung des Linsensystems.conditioned by adjustable arrangement of the projection unit can be different projection surfaces in the vehicle interior for viewing image information to simple Select way. The adjustment of the image sharpness takes place via the electronic compensation module by signaling to change the movement of the lens system.
Eine vorteilhafte Weiterbildung der Anordnung besteht darin, die Projektionseinrichtung an verschiedene, im Fahrzeuginnenraum vorgesehene Aufnahmepunkte anzukoppeln. An jedem Aufnahmepunkt liegt dabei eine Verbindung zum elektronischen Kompensationsmodul vor, so dass unabhängig von der Projektionsrichtung entsprechend der Profilierung der Projektionsfläche eine selbsttätige Fokussierung über das Linsensystem in Verbindung mit der Signalgebung des elektronischen Kompensationsmoduls realisiert wird. Dies ermöglicht beispielweise, dass die sich auf den Rücksitzen befindlichen Insassen Bildinformationen, beispielsweise in Form von Video- oder TV-Signalen, wahrnehmen können, ohne dass die Informationen den Fahrer beeinflussen.A advantageous development of the arrangement is the projection device to various, provided in the vehicle interior receiving points to dock. There is a connection at each pickup point to the electronic compensation module, so that regardless of the projection direction according to the profiling of the projection a automatic focus on the Lens system in conjunction with the signaling of the electronic Compensation module is realized. This allows, for example, that who are in the back seats occupants image information, for example in the form of Video or TV signals, can perceive without the information influence the driver.
Zweckmäßigerweise besteht die Beleuchtungsoptik der Projektionseinheit aus einer Anordnung von Lumineszenzdioden (LEDs), da derartige Beleuchtungsquellen im zunehmenden Maße in der Projektionstechnik Anwendung finden und sich gerade durch ihre Baugröße als vorteilhaft in Fahrzeug auswirken.Conveniently, the illumination optics of the projection unit consists of an arrangement of light emitting diodes (LEDs), since such illumination sources in increasing dimensions to find application in projection technology and get straight through their size is advantageous in vehicle affect.
Wie bereits aus den Lösungen des Standes der Technik bekannt, ist es sinnvoll, die Projektionsfläche so auszubilden, dass eine definierte Begrenzung des Betrachtungsfeldes zum Fahrzeuginsassen, der die Informationen wahrnehmen will, vorliegt und ein weiterer Insasse, der von den Informationen nicht gestört werden möchte, diese nicht sieht.As already out of the solutions known in the prior art, it is useful to form the projection surface so that a defined limitation of the field of view to the vehicle occupant, who wants to perceive the information is present and another Inmate who does not want to be disturbed by the information, does not see this.
Denkbar ist es dabei, die Projektionsfläche an das Innenraumdesign anzupassen und direkt in die Bauteile des Fahrzeuges zu integrieren. Um Verschmutzungen zu vermeiden wäre es dabei sinnvoll, die Projektionsflächen in den Bauteilen versenkbar anzuordnen.Conceivable it is about the projection surface to adapt the interior design and directly into the components of the vehicle to integrate. To avoid contamination it would be there useful, the projection screens to arrange retractable in the components.
Die Gestaltung der Projektionsfläche mit einer reflektierenden Fresnellstruktur wäre dabei eine zweckmäßige Variante, wobei diese auf oder im Armaturenbrett oder auch beispielhaft in den Rückseiten der Kopfstützen integriert sein kann.The Design of the projection screen with a reflective Fresnellstruktur would be an expedient variant, being on or in the dashboard or even exemplarily in the backs the headrests can be integrated.
Eine andere Variante besteht darin, die Projektionsfläche so auszubilden, dass sie an verschiedenen Stellen im Fahrzeuginnenraum befestigt werden kann. Dies hätte den Vorteil, dass der Ort der Darstellung der Bildinformationen an die Sitzposition des Insassen angepasst werden könnte. Die Projektionsfläche ließe sich ohne großen Aufwand gegen eine anders strukturierte oder eine in den Abmaßen veränderte Fläche ersetzten, um somit auch das Betrachtungsfeld an die Betrachter anzupassen.A Another variant is to form the projection surface in such a way that they can be attached to various locations in the vehicle interior. This would have the advantage that the place of presentation of the image information could be adapted to the seating position of the occupant. The projection could without a big one Expenditure against a differently structured surface or an area modified in the dimensions, thus to adapt the field of view to the viewer.
Denkbar wäre auch eine mobile komplette Projektionseinheit in Verbindung mit einer Auswahl von Projektionsflächen als relativ preisgünstiges Zubehörset, welches dann zur Nachrüstung in älteren Fahrzeugen geeignet wäre.Conceivable would be too a mobile complete projection unit in conjunction with a Selection of projection screens as relatively inexpensive Accessory Set which then for retrofitting in older vehicles would be suitable.
Anhand eines Ausführungsbeispiels soll die erfindungsgemäße Projektionsanordnung näher erläutert werden.Based an embodiment should the projection arrangement according to the invention be explained in more detail.
