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 ePaper, which is arranged on the 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, traffic light systems (traffic lights) and traffic rules, so that even in usually crowded metropolitan areas with a large number of different road users there is an essentially undisturbed traffic flow. Nevertheless, traffic situations regularly occur in which the existing regulations do not provide clear rules for action for road users. In such cases, the drivers of the affected vehicles must communicate with one another directly via eye contact or other gestures and resolve the existing traffic situation with one another.
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 fahrenden 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 participate. While autonomous and semi-autonomous vehicles can use Car2Car communication to coordinate any right of way, comparable communication between autonomous vehicles and conventional road users is ruled out. Situations that require direct communication between such road users can then no longer be resolved immediately by eye contact, which will lead to a sluggish flow of traffic and which can provoke the causes of accidents. In addition, autonomously driving vehicles do not differ externally from conventional vehicles, so that road users cannot immediately recognize whether it is possible and sensible to contact the vehicle occupant.
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 can emit warning messages, such as traffic jam warnings or the like, in addition to conventional light signals. 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 vergleichsweisen 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 according to the prior art usually have LCD displays or LED matrices, which, however, have to be permanently energized in order to display the desired information, which is associated with a comparatively high energy consumption. Furthermore, such display devices result in poor readability, particularly in the case of solar radiation, and known display devices have a sensitive surface due to the required installation space depth.
Neben LCD-Displays und LED-Matrizen ist 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
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 which has a comparatively low power consumption, can be installed easily and cost-effectively and is low-maintenance and also shows recognizable information in adverse viewing conditions, in particular in the dark.
Diese Aufgabe wird durch die Anzeigevorrichtung nach Anspruch 1 gelöst. Erfindungsgemäß besitzt die Anzeigevorrichtung eine Streuscheibe und mehrere Lichtquellen, die derart ausgerichtet sind, dass das abgestrahlte Licht über Lichteintrittsflächen in die Streuscheibe einkoppelt und nach einer Reflexion am Display über eine Lichtaustrittsfläche aus der Streuscheibe auskoppelt. 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.This object is achieved by the display device according to
Bevorzugte Ausgestaltungen der vorliegenden Erfindung werden nachfolgend und in den Unteransprüchen angegeben.Preferred embodiments of the present invention are specified below and in the subclaims.
Nach einer ersten bevorzugten Ausführungsform der vorliegenden Erfindung ist vorgesehen, dass die Anordnung der Lichtquellen die Streuscheibe (zumindest abschnittsweise) umringt. Das bedeutet, dass die Lichtquellen im Wesentlichen ringförmig am Rand der Streuscheibe angeordnet sind und das Licht in die Streuscheibe einkoppeln, wodurch eine direkte Beleuchtung des Betrachters vermieden wird. Hierbei sind im Wesentlichen zwei unterschiedliche Ausführungsformen vorgesehen.According to a first preferred embodiment of the present invention, it is provided that the arrangement of the light sources surrounds the lens (at least in sections). This means that the light sources are arranged essentially in a ring on the edge of the lens and couple the light into the lens, thereby avoiding direct illumination of the viewer. Essentially two different embodiments are provided here.
Zunächst ist nach einer bevorzugten Ausgestaltung vorgesehen, das die Lichteintrittsflächen seitlich an der Streuscheibe angeordnet sind. Mithin sind auch die Lichtquellen derart angeordnet und ausgerichtet, dass das Licht durch die seitlichen Lichteintrittsflächen der Streuscheiben einkoppelt.First, according to a preferred embodiment, it is provided that the light entry surfaces are arranged on the side of the lens. Consequently, the light sources are also arranged and aligned in such a way that the light is coupled in through the lateral light entry surfaces of the diffusing screens.
Alternativ 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.Alternatively, an angled light coupling and a corresponding light source alignment are also provided, in which case reflection elements are arranged which allow the light to be coupled into the scattering disc in an aligned manner.
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 predefinable color and intensity, so that colored warning notices, advertisements and the like can also be displayed with the display device. Through targeted control of the individual light sources in relation to their respective color and / or respective intensity, individual points on the display surface can be optically highlighted by a high light intensity and / or another color, so that so-called hot spots can essentially be freely positioned on the display device . The illumination of the display device designed in this way also enables the light intensity to be changed over time, so that flashing effects and the like can be represented.
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 diffusing screen 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 substantially equal to the light intensity at the edge of the display device and therefore in close proximity to the light sources. For this purpose, too, the diffusing screen for coupling out the light has a preferred direction, according to which the coupled light is first reflected or scattered in the direction of the ePaper display after being coupled into the diffusing plate, so that the outcoupled light has been 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. The lens is preferably permanently connected to the display, the lens being preferably glued to the display. This sandwich construction results in a so-called optical bonding, which prevents an air gap between the lens and the ePaper display, which otherwise leads to a blurred or washed-out image.
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 influenced and to maintain the aerodynamic properties of the body, it is provided according to a preferred embodiment of the invention that the light exit surface of the lens 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. For example, a magnetic attachment is provided as a releasable 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 lens of the display device is preferably made of PMMA (acrylic glass), which is an insensitive surface that can also be 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.
