Description
Die vorliegende Erfindung betrifft eine Anzeigevorrichtung für ein Fahrzeug mit einem als ePaper ausgestalteten Display, das zur Außenkommunikation an einer Außenseite des Fahrzeugs angeordnet ist.The present invention relates to a display device for a vehicle with a display designed as an e-paper, which is arranged on an outside of the vehicle for external communication.
Der heutige Straßenverkehr wird durch eine Vielzahl von Verkehrszeichen, Lichtzeichenanlagen (Ampeln) und Verkehrsregeln geregelt, so dass sich selbst in üblicherweise überfüllten Ballungsgebieten mit einer Vielzahl von unterschiedlichen Verkehrsteilnehmern ein im Wesentlichen ungestörter Verkehrsfluss ergibt. Nichtsdestotrotz treten regelmäßig Verkehrssituationen auf, in denen die vorhandenen Regelungen keine eindeutige Handlungsvorschrift für die Verkehrsteilnehmer liefern. In solchen Fällen müssen die Fahrer der betroffenen Fahrzeuge unmittelbar über Blickkontakt oder sonstige Gesten miteinander kommunizieren und die vorhandene Verkehrssituation miteinander auflösen.Today's road traffic is regulated by a large number of traffic signs, light signal systems (traffic lights) and traffic rules, so that there is an essentially undisturbed flow of traffic even in usually overcrowded conurbations with a large number of different road users. Nevertheless, traffic situations occur regularly in which the existing regulations do not provide any clear instructions for road users. In such cases, the drivers of the affected vehicles have to communicate with each other directly through eye contact or other gestures and resolve the existing traffic situation with each other.
Im zukünftigen Straßenverkehr werden neben herkömmlichen Verkehrsteilnehmern auch autonom und/oder teilautonom fahrende Fahrzeuge (bemannt und/oder unbemannt) teilnehmen. Während autonom und teilautonom fahrende Fahrzeuge über Car2Car-Kommunikation unmittelbar etwaige Vorfahrtsberechtigungen abstimmen können, scheidet eine vergleichbare Kommunikation zwischen autonom fahrenden Fahrzeugen und herkömmlichen Verkehrsteilnehmern aus. Situationen, die eine unmittelbare Kommunikation zwischen solchen Verkehrsteilnehmern erfordern, können dann nicht mehr unmittelbar durch einen Blickkontakt aufgelöst werden, was zu einem stockenden Verkehrsfluss führen wird und was Unfallursachen provozieren kann. Hinzu kommt, dass sich autonom fahrende Fahrzeuge äußerlich nicht von herkömmlichen Fahrzeugen unterscheiden, so dass Verkehrsteilnehmer nicht unmittelbar erkennen können, ob eine Kontaktaufnahme mit dem Fahrzeuginsassen möglich und ggf. sinnvoll ist.In future road traffic, in addition to conventional road users, autonomous and/or semi-autonomous vehicles (manned and/or unmanned) will also take part. While autonomous and semi-autonomous vehicles can use Car2Car communication to immediately coordinate any right of way, comparable communication between autonomous vehicles and conventional road users is out of the question. Situations that require direct communication between such road users can then no longer be resolved immediately through eye contact, which will lead to a slowdown in traffic flow and which can provoke causes of accidents. In addition, autonomously driving vehicles do not look any different from conventional vehicles, so that road users cannot immediately see whether contact with the vehicle occupant is possible and possibly useful.
Aus dem Stand der Technik sind zusätzliche Anzeigevorrichtungen in Form von Displays bekannt, die an den Fahrzeugaußenseiten angeordnet sind und die über herkömmliche Lichtzeichen hinaus Warnmeldungen, wie beispielsweise Stauwarnungen oder dergleichen abgeben können. Auch Werbeinformationen sind auf derartigen Anzeigevorrichtungen darstellbar.Additional display devices in the form of displays are known from the prior art, which are arranged on the outside of the vehicle and which, in addition to conventional light signals, can emit warning messages, such as traffic jam warnings or the like. Advertising information can also be displayed on such display devices.
Die nach dem Stand der Technik bekannten Anzeigevorrichtungen weisen üblicherweise LCD-Displays oder LED-Matrizen auf, die jedoch zur Anzeige der gewünschten Informationen dauerhaft bestromt werden müssen, was mit einem vergleichsweise hohen Energieverbrauch verbunden ist. Ferner ergibt sich bei solchen Anzeigevorrichtungen insbesondere bei Sonneneinstrahlung eine schlechte Lesbarkeit und aufgrund der erforderlichen Bauraumtiefe besitzen bekannte. Anzeigevorrichtungen eine empfindliche Oberfläche.The display devices known from the prior art usually have LCD displays or LED matrices, which, however, have to be permanently supplied with current in order to display the desired information, which is associated with a comparatively high energy consumption. Furthermore, such display devices are poorly legible, particularly in direct sunlight, and known ones have them due to the required installation space depth. Display devices have a sensitive surface.
Neben LCD-Displays und LED-Matrizen sind aus
Weil ePaper-Displays konstruktionsbedingt keine aktiven Anzeigeelemente aufweisen, d.h.. aktiv leuchtende Pixel, sind derartige Anzeigevorrichtungen jedoch bei Dunkelheit und geringer Beleuchtung schlecht erkennbar. Im Rahmen von der bereits angesprochenen
Aus
Hiervon ausgehend ist es die Aufgabe der vorliegenden Erfindung, eine Anzeigevorrichtung für ein Fahrzeug vorzuschlagen, die einen vergleichsweise geringen Stromverbrauch aufweist, einfach und kostenschonend montierbar sowie wartungsarm ist und auch bei widrigen Sichtbedingungen, insbesondere bei Dunkelheit, erkennbare Informationen darstellt.Proceeding from this, it is the object of the present invention to propose a display device for a vehicle that has comparatively low power consumption, is easy and inexpensive to assemble and requires little maintenance, and displays recognizable information even under poor visibility conditions, particularly in the dark.
Durch die indirekte Beleuchtung des Displays nimmt der Betrachter die Beleuchtung nur als Reflexion von der Displayoberfläche wahr, womit eine Blendung durch direktes Licht verhindert wird, wie es bei Anzeigevorrichtungen bekannter Bauart zu beobachten ist. Zudem wird mit einer geringen Helligkeit eine gute Sichtbarkeit des dargestellten Inhalts auf dem Display erreicht, was sich positiv auf den Energieverbrauch der Anzeigevorrichtung auswirkt. Weil hierdurch auch auf ein zusätzliches aktiv leuchtendes Display verzichtet werden kann, ist die erfindungsgemäße Anzeigevorrichtung einfach und kostenschonend zu montieren und zu warten.Due to the indirect lighting of the display, the viewer only perceives the lighting as reflection from the display surface, preventing glare from direct light seen in prior art displays. In addition, good visibility of the content shown on the display is achieved with low brightness, which has a positive effect on the energy consumption of the display device. Because this also makes it possible to dispense with an additional actively luminous display, the display device according to the invention can be installed and maintained easily and inexpensively.
Bevorzugte Ausgestaltungen der vorliegenden Erfindung werden nachfolgend und in den Unteransprüchen angegeben.Preferred developments of the present invention are specified below and in the dependent claims.
Es ist auch eine winklige Lichteinkopplung und eine entsprechende Lichtquellenausrichtung vorgesehen, wobei in diesem Fall Reflexionselemente angeordnet sind, die eine ausgerichtete Einkopplung des Lichts in die Streuscheibe erlauben.Angular light coupling and a corresponding light source alignment are also provided, with reflection elements being arranged in this case, which allow the light to be coupled in an aligned manner into the diffuser.
Als bevorzugte Lichtquellen haben sich Leuchtdioden (LEDs) oder Laserdioden erwiesen, die vorzugsweise Licht in beliebiger und vorgebbarer Farbe und Intensität erzeugen, so dass mit der Anzeigevorrichtung auch farbige Warnhinweise, Werbung und dergleichen dargestellt werden kann. Durch eine gezielte Steuerung der einzelnen Lichtquellen in Bezug auf ihre jeweilige Farbe und/oder jeweilige Intensität können einzelne Punkte auf der Displayoberfläche optisch durch eine hohe Lichtintensität und/oder eine andere Farbe hervorgehoben werden, so dass sogenannte Hotspots auf der Anzeigevorrichtung im Wesentlichen frei positionierbar sind. Die derart ausgestaltete Beleuchtung der Anzeigevorrichtung ermöglicht auch eine zeitliche Veränderung der Lichtintensität, so dass Blinkeffekte und dergleichen darstellbar sind.Light-emitting diodes (LEDs) or laser diodes have proven to be preferred light sources, which preferably generate light in any desired and definable color and intensity, so that colored warnings, advertising and the like can also be displayed with the display device. Targeted control of the individual light sources with regard to their respective color and/or respective intensity allows individual points on the display surface to be visually emphasized by a high light intensity and/or a different color, so that so-called hotspots on the display device can essentially be freely positioned . The lighting of the display device configured in this way also enables the light intensity to change over time, so that flashing effects and the like can be displayed.
Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Streuscheibe eingerichtet ist, um eine homogene Lichtverteilung an der Lichteintrittsfläche zu erzeugen. Hiernach ist die abgestrahlte Lichtintensität in der Mitte der Anzeigevorrichtung zumindest im Wesentlichen gleich zu der Lichtintensität am Rand der Anzeigevorrichtung und mithin in unmittelbarer Nähe zu den Lichtquellen. Auch hierzu weist die Streuscheibe für die Lichtauskopplung eine Vorzugsrichtung auf, wonach das eingekoppelte Licht nach der Einkopplung in die Streuscheibe zunächst in Richtung des ePaper-Displays reflektiert oder gestreut wird, so dass das ausgekoppelte Licht zumindest einmal an der Oberfläche des ePaper-Displays reflektiert wurde.According to a further preferred embodiment of the invention, it is provided that the diffuser is set up in order to generate a homogeneous light distribution on the light entry surface. According to this, the emitted light intensity in the center of the display device is at least essentially equal to the light intensity at the edge of the display device and therefore in the immediate vicinity of the light sources. Here, too, the diffusing screen for the light extraction has a preferred direction, after which the coupled-in light, after being coupled into the diffusing screen, is first reflected or scattered in the direction of the ePaper display, so that the extracted light is reflected at least once on the surface of the ePaper display .
Die Streuscheibe besitzt nach einer weiteren bevorzugten Ausgestaltung der Erfindung eine Anlagefläche zum Display und deckt das Display zumindest teilweise, vorzugsweise vollständig, ab. Dabei ist die Streuscheibe vorzugsweise unlösbar mit dem Display verbunden, wobei die Streuscheibe vorzugsweise mit dem Display verklebt ist. Durch diese Sandwich-Bauweise ergibt sich ein sog. optischen Bonding, das einen Luftspalt zwischen der Streuscheibe und dem ePaper-Display verhindert, der anderenfalls zu einer unscharfen oder verwaschenen Abbildung der Darstellung führt.According to a further preferred embodiment of the invention, the lens has a contact surface for the display and covers the display at least partially, preferably completely. In this case, the diffuser is preferably non-detachably connected to the display, with the diffuser preferably being glued to the display. This sandwich construction results in a so-called optical bonding, which prevents an air gap between the diffuser and the ePaper display, which would otherwise result in a blurred or washed-out image of the display.
Damit der optische Eindruck eines Fahrzeugs mit einer erfindungsgemäßen Anzeigevorrichtung nicht beeinflusst wird und um die aerodynamischen Eigenschaften der Karosserie zu erhalten, ist nach einer bevorzugten Ausgestaltung der Erfindung vorgesehen, dass die Lichtaustrittsfläche der Streuscheibe an die Außenkontur des Fahrzeugs angepasst ist. Hierzu kann die Außenkontur der Streuscheibe entsprechend gefräst und/oder poliert sein.So that the visual impression of a vehicle with a display device according to the invention is not affected and in order to maintain the aerodynamic properties of the body, a preferred embodiment of the invention provides that the light exit surface of the diffuser is adapted to the outer contour of the vehicle. For this purpose, the outer contour of the lens can be milled and/or polished accordingly.
Die Anzeigevorrichtung ist vorzugsweise lösbar oder unlösbar mit der Fahrzeugkarosserie verbunden, so dass sich die Anzeigevorrichtung auch als Nachrüstsatz für bereits vorhandene Fahrzeuge ohne eine fest installierte Anzeigevorrichtung eignet. Als lösbare Befestigung ist beispielsweise eine magnetische Befestigung vorgesehen.The display device is preferably detachably or non-detachably connected to the vehicle body, so that the display device is also suitable as a retrofit kit for existing vehicles without a permanently installed display device. A magnetic attachment, for example, is provided as a detachable attachment.
Die Streuscheibe der Anzeigevorrichtung besteht vorzugsweise aus PMMA (Acrylglas), was eine unempfindliche Oberfläche darstellt, die darüber hinaus den gewünschten Bedingungen durch Fräsen und/oder Polieren gut angepasst werden kann. Im Übrigen hat PMMA gegenüber anderen lichtdurchlässigen Materialien, wie beispielsweise Glas, den Vorteil, dass PMMA bei einem etwaigen Unfall oder einer sonstigen Krafteinwirkung nicht splittert.The diffuser of the display device is preferably made of PMMA (acrylic glass), which represents a non-sensitive surface that can also be easily adapted to the desired conditions by milling and/or polishing. In addition, PMMA has the advantage over other translucent materials such as glass that PMMA does not splinter in the event of an accident or other force.
