Abstract

The invention relates to a signaling device (1) for displaying and/or outputting warning signals and/or information in vehicles by means of optical and/or acoustic signal sources. According to the invention, a signal provided for example by a collision avoidance system, is used to output direction-related information for the driver of a vehicle. Said information is connected with an event related to a certain object to which event attention is to be drawn. Figure 1 is a schematic representation of the top view of a signaling device (1) comprising a vehicle windshield (2) and display elements (4) distributed therein, and an enlarged detail drawing (10) in a sectional side view of a display element (4a) arranged in the vehicle windshield (2). The right-hand portion of Figure 1 shows the top view of the vehicle windshield (2) across a substantial part (3) of which display elements (4) are distributed. Only the display element (4a) is active. For this purpose, a light beam is guided, starting from a fiber-optical waveguide (5), onto the display element (4) which becomes visible to the driver of the vehicle due to the illumination by the light beam. The remaining display elements (4) are invisible to the driver of the vehicle. The vehicle windshield (2), in this drawing, is configured as a two-layer laminated windshield between the two parts (2, 2) of which both the display elements (4) and the fiber-optical waveguides (5) are arranged.

Description

"Signalisiervorrichtung zur Anzeige von Warn- und /oder Informationshinweisen in Fahrzeugen." "Signaling device for displaying warning and / or information notices in vehicles."
Stand der Technik:State of the art:
Zur Erhöhung der Verkehrssicherheit von Fahrzeugen ist es bekannt dem Fahrzeuglenker wichtige Informationen direkt in seinem Sichtfeld an der Windschutzscheibe anzuzeigen, so dass ■ er den Blick nicht mehr vom Verkehrsgeschehen abwenden muss, wenn er diese Informationen erfassen möchte. Aus der DE 41 27 656 AI ist in diesem Zusammenhang ein Elektroluminiszenz- Dislplay (ELD) bekannt, welches im unteren Sichtbereich der Fahrzeugscheibe über dem Lenkrad als matrixför ige Struktur angeordnet ist. Dadurch können gezielt einzelne Punkte aus der Matrix zur Erzeugung eines Warn- und/oder Informationshinweises sichtbar gemacht werden.To increase road safety of vehicles it is known to display the vehicle driver important information directly in his field of vision on the windscreen so that it no longer ■ to look away from the road needs to if he wants to capture this information. From DE 41 27 656 AI an electroluminescent display (ELD) is known in this connection, which is arranged in the lower viewing area of the vehicle window above the steering wheel as a matrix-like structure. This allows individual points from the matrix to be made visible in order to generate a warning and / or information notice.
Im Weiteren sind KollisionsvermeidungsSysteme bekannt, die die Umgebung des Fahrzeugs nach Objekten sondieren, welche gegebenenfalls ein Kollisionsereignis begründen könnten. Diese Kollisionsvermeidungssysteme liefern bei der Erkennung eines entsprechenden Objektes ein Signal, welches ausgewertet und dem Fahrzeuglenker optisch oder akustisch mitgeteilt werden kann. Die optische Anzeige kann beispielsweise mittels eines ELD nach der DE 41 27 656 AI angezeigt werden.Furthermore, collision avoidance systems are known which probe the surroundings of the vehicle for objects which could possibly justify a collision event. When a corresponding object is detected, these collision avoidance systems deliver a signal which can be evaluated and communicated visually or acoustically to the vehicle driver. The optical display can be displayed for example by means of an ELD according to DE 41 27 656 AI.
Eine weitere optische Anzeige geht aus der DE 101 47 271 AI hervor, die ein Fahrzeugblinker-System beschreibt, bei dem am linken und rechten äußeren Rand einer Fahrzeugscheibe Reflexionsmittel eingebracht sind, die einen in die Fahrzeugscheibe eingestrahlten Lichtstrahl zur Anzeige der Blinkerfunktion für andere Verkehrteilnehmer nach außen reflektieren. Als Reflexionsmaterial werden Silberstreifen oder Silberpigmente offenbart, die aufgrund ihrer kleinen geometrischen Strukturen am Rande der Scheibe zwar nur unwesentlich den Blick durch die Fahrzeugscheibe stören, aber dennoch das Blickfeld einschränken.A further optical display is shown in DE 101 47 271 AI, which describes a vehicle turn signal system in which reflection means are introduced on the left and right outer edge of a vehicle window, which emit a beam of light irradiated into the vehicle window to indicate the turn signal function for other road users Outside reflect. Silver strips or silver pigments are disclosed as reflection material, which, because of their small geometric structures on the edge of the pane, only slightly disturb the view through the vehicle pane, but nevertheless restrict the field of vision.
Eine akustische Abgabe eines Warn- und/oder Informationshinweises ist beispielsweise aus Fahrzeugen bekannt, die in Stoßstangen Abstandssensoren enthalten, welche bei unterschreiten eines bestimmten Abstandes ein Signal für eine akustische Anzeige zur Warnung des Fahrzeuglenkers generieren.An acoustic output of a warning and / or information notice is known, for example, from vehicles which contain distance sensors in bumpers, which generate a signal for an acoustic display to warn the driver when the distance falls below a certain distance.
Aufgabe und Vorteile der Erfindung:Object and advantages of the invention:
Aufgabe der vorliegenden Erfindung ist es, die Verkehrssicherheit und/oder den Komfort beim Betrieb eines Fahrzeugs weiter zu erhöhen.The object of the present invention is to further increase traffic safety and / or comfort when operating a vehicle.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. In den abhängigen Ansprüchen sind vorteilhafte und zweckmäßige Weiterbildungen der Erfindung angegeben.This object is solved by the features of the independent claims. Advantageous and expedient developments of the invention are specified in the dependent claims.
Zunächst geht die Erfindung von einer Signalisiervorrichtung zur Anzeige von Warn- und/oder Informationshinweisen in Fahrzeugen mit wenigstens einem innerhalb des sichtbaren Bereichs einer Fahrzeugscheibe liegenden und an ihr angeordneten, optischen Anzeigeelement aus. Der Kern der Erfindung liegt nun darin, dass mehrere Anzeigeelemente in einem wesentlichen Bereich der Fahrzeugscheibe, insbesondere an oder in der Fahrzeugscheibe angeordnet sind, und zur Anzeige eines Warn- und/oder Informationshinweises selektiv sichtbar gemacht werden können.First of all, the invention is based on a signaling device for displaying warning and / or information notices in vehicles with at least one optical display element located within the visible area of a vehicle window and arranged on it. The essence of the invention lies in the fact that a plurality of display elements are arranged in an essential area of the vehicle window, in particular on or in the vehicle window, and can be made selectively visible for displaying a warning and / or information notice.
Der wesentliche Teil der Fahrzeugscheibe bezieht sich insbesondere auf den wesentlichen Teil der Breite der Fahrzeugscheibe, der sich aus dem für die Fahraufgabe relevanten Sichtfeld ergibt. Es sollen dem Fahrzeuglenker vom linken bis zum rechten Scheibenrand verteilt bedarfsweise Informationen angezeigt werden können. Entsprechend kann sich der wesentliche Teil der Fahrzeugscheibe auch noch über einen wesentlichen Teil der Höhe der Fahrzeugscheibe erstrecken, wodurch die gesamte bzw. nahezu die gesamte Fahrzeugscheibe als Anzeigefläche genutzt werden kann.The main part of the vehicle window relates in particular on the essential part of the width of the vehicle window, which results from the field of view relevant to the driving task. The driver should be able to display information from the left to the right edge of the pane as needed. Accordingly, the essential part of the vehicle window can also extend over a substantial part of the height of the vehicle window, so that the entire or almost the entire vehicle window can be used as a display area.
Der Vorteil einer solchen Verteilung von Anzeigeelementen liegt darin, dass dem Fahrzeuglenker durch die Aktivierung eines bestimmten Anzeigeelementes eine kontaktanaloge Information über die Richtung gegeben werden kann, aus welcher Richtung er mit einem das Verkehrsgeschehen beeinflussenden Objekt rechnen muss. Dies geschieht dadurch, dass jenes Anzeigeelement sichtbar gemacht wird, welches direkt auf der Sichtlinie liegt, welche sich zwischen dem Auge/Kopf des Fahrzeuglenkers und einem mittels einer die Umgebung des Fahrzeugs detektierenden Vorrichtung detektiertem Objekt ergibt. Durch das sichtbar gemachte Anzeigeelement blickt der Fahrzeuglenker automatisch in die Richtung des Objekts. Liegt das Objekt noch nicht im theoretischen Sichtbereich des Fahrzeuglenkers, können Anzeigeelemente im Randbereich der Scheibe aktiviert werden um deutlich zu machen, in welcher Richtung das Objekt zu beachten ist.The advantage of such a distribution of display elements is that by activating a specific display element, the vehicle driver can be given contact-analogous information about the direction from which direction he has to reckon with an object influencing the traffic situation. This is done by making visible that display element which lies directly on the line of sight which results between the eye / head of the vehicle driver and an object detected by means of a device which detects the surroundings of the vehicle. The vehicle driver automatically looks in the direction of the object through the display element made visible. If the object is not yet in the theoretical field of vision of the driver, display elements can be activated in the edge area of the pane to make it clear in which direction the object is to be observed.
Die Anzeigeelemente können in einer einfachen Ausführungsform bereits in der Struktur ausgebildet sein, in der sie dem Fahrzeuglenker als Signal bzw. Hinweis durch Sichtbarmachung angezeigt werden.In a simple embodiment, the display elements can already be designed in the structure in which they are displayed to the vehicle driver as a signal or indication by visualization.
Somit ist ihre Aktivierung durch einfache Mittel möglich. Es muss dazu lediglich ein einziges Signal generiert werden, um ein Anzeigeelement mit dem ihm zugeordneten Sichtbarmachungsmittel für den Fahrzeuglenker sichtbar zu machen. Die Anzeigeelemente können aber auch komplexere Strukturen aufweisen. Beispielsweise können sie jeweils als eine eigenständige Matrix aufgebaut sein. Sie können auch als mehrteilige Struktur mit einer Mehrzahl von gleichen oder unterschiedlichen Anzeigesymbolen ausgebildet sein, die am selben Anzeigeort mit unterschiedlicher Größe übereinander oder sich gegebenenfalls umschließend angeordnet sind. Somit ist es möglich das Anzeigesyrαbol in seiner Form und/oder seiner Größe zu variieren und damit zusätzliche Aufmerksamkeit zu erzeugen bzw. Informationen zu übermitteln.They can thus be activated by simple means. All that is required is to generate a single signal in order to make a display element with the visualization means assigned to it visible to the vehicle driver. However, the display elements can also have more complex structures. For example, they can each be constructed as an independent matrix. They can also be designed as a multi-part structure with a plurality of the same or different display symbols, which are arranged at the same display location with different sizes one above the other or, if appropriate, surrounding one another. It is thus possible to vary the shape and / or size of the display symbol and thus to generate additional attention or to transmit information.
Die Anzeige kann permanent erfolgen oder blinkend, mit konstanter oder veränderlicher Frequenz .-Auch können mehrere Anzeigeelemente gleichzeitig oder sequentiell sichtbar gemacht werden, insbesondere abhängig davon, welche Information mitgeteilt werden soll.The display can be permanent or flashing, with a constant or variable frequency. Also, several display elements can be made visible simultaneously or sequentially, in particular depending on which information is to be communicated.
Ein weiterer wesentlicher Aspekt der Erfindung ist, dass wenigstens einem Anzeigeelement zur Lichtversorgung ein kanalförmiger Lichtleiter zugeordnet ist, insbesondere ein Lichtleiter mit Seitenwänden in Kanalrichtung zur lateralen Begrenzung der Lichtführung in Bezug auf die flächige Erstreckung der Fahrzeugscheibe.A further essential aspect of the invention is that a channel-shaped light guide is assigned to at least one display element for light supply, in particular a light guide with side walls in the channel direction for the lateral limitation of the light guidance with respect to the areal extent of the vehicle window.
Das zur Sichtbarmachung des Anzeigeelements eingestrahlte Licht ist im Lichtleiter gefangen und kann nur an dessen Stirnseiten ein- bzw. austreten, wodurch auch eine Vielzahl von Anzeigeelementen voneinander unabhängig selektiv versorgt werden können.The light radiated in to make the display element visible is caught in the light guide and can only enter or exit at its end faces, as a result of which a large number of display elements can also be supplied selectively independently of one another.
Die Ausbildung des Lichtleiters als von der Fahrzeugscheibe separater Lichtleiter, eventuell als Lichtleitfaser, stellt eine mögliche Ausführungsform dar. Die Lichtführung ist damit in einem weiten Anordnungsbereich flexibel gestaltbar, gegebenenfalls sogar mit sich kreuzenden oder gebündelt geführten Lichtleitern. In einer weiteren Ausführungsform besteht die Möglichkeit, den bzw. die Lichtleiter als Struktur in einer Folie oder einer Scheibe, z.B. als strukturierte Folie oder Scheibe oder auch als strukturierte Beschichtung in einer solchen auszubilden.The design of the light guide as a light guide separate from the vehicle window, possibly as an optical fiber, represents a possible embodiment. The light guidance can thus be configured flexibly in a wide range of arrangements, possibly even with light guides crossing or bundled. In a further embodiment, there is the possibility of forming the light guide (s) as a structure in a film or a pane, for example as a structured film or pane or as a structured coating in such a film.
Weitere Variationsmöglichkeiten in der Signalisierung von Hinweisen eröffnen sich bei einer Zuordnung mehrerer Lichtleiter pro Anzeigeelement. Beispielsweise können die Anzeigeelemente mit verschiednen Lichtquellen aktiviert werden, wodurch ein und dieselben Anzeigeelementform mehrere Informationen wiedergeben kann .Further variation possibilities in the signaling of notices open up by assigning several light guides per display element. For example, the display elements can be activated with different light sources, as a result of which one and the same display element shape can reproduce more information.
In"einer besonders bevorzugten Ausgestaltung der Erfindung sind die Anzeigeelemente als Strukturen ausgebildet, die im deaktivierten Zustand nicht sichtbar sind. Dadurch ergibt sich beispielsweise gegenüber der Blinkerausführung mit den Silberstreifen der Vorteil, dass im inaktiven Zustand keine Strukturen in der Scheibe die Aufmerksamkeit des Fahrzeuglenkers stören.In a particularly preferred embodiment of the invention, the display elements are designed as structures which are not visible in the deactivated state. This has the advantage, for example, compared to the turn signal version with the silver strips, that no structures in the window disrupt the driver's attention in the inactive state ,
Die Anordnung einer Lichtquelle ermöglicht die Versorgung der Anzeigeelemente zu deren Sichtbarmachung mit Licht. Für die Versorgung der Anzeigeelemente können auch mehrere Lichtquellen zur Verfügung stehen, so dass die Anzeigeelemente einzeln, gruppenweise einfarbig oder auch mehrfarbig sichtbar gemacht werden können.The arrangement of a light source enables the display elements to be supplied with light to make them visible. Several light sources can also be provided for supplying the display elements, so that the display elements can be made visible individually, in groups in one color or also in multiple colors.
Es ist ebenfalls denkbar, dass die Anzeigeelemente als Hologramme ausgebildet sind. Dadurch ist es beispielsweise möglich, dass die Anzeigeelemente lediglich mittels eines Laserlichtes sichtbar gemacht werde können. Ungünstige Einstrahlungen aus anderen Lichtquellen können dann die Anzeigeelemente nicht versehentlich aktivieren um den Fahrzeuglenker gegebenenfalls durch eine falsche Anzeige zu irritieren. In einer nächsten, vorteilhaften. Ausführungsform kann es vorgesehen sein, dass die Anzeigeelemente als aktiv Licht emittierende Elemente ausgebildet sind. Dabei kann gegebenenfalls auf eine Lichtzuführung verzichtet werden und die Versorgung der Anzeigeelemente mit Energie zur Sichtbarmachung mittels einfach anzubringender elektrischer Leitungen erfolgen. Eine Kombination mit den zuvor beschriebenen Ausführungsformen ist aber dennoch grundsätzlich möglich.It is also conceivable that the display elements are designed as holograms. This makes it possible, for example, for the display elements to be made visible only by means of a laser light. Unfavorable radiation from other light sources can then inadvertently activate the display elements in order to possibly irritate the vehicle driver with an incorrect display. In a next, advantageous one. Embodiment, it can be provided that the display elements are designed as active light-emitting elements. It may be possible to dispense with a light supply and the display elements are supplied with energy for visualization by means of electrical cables which are easy to attach. However, a combination with the previously described embodiments is still possible in principle.
In einer bevorzugten Ausführungsform können die Anzeigeelemente als TOLED (Transparent Organic Light Emmitting Device) ausgebildet sein. Diese organischen Displays sind im deaktiven, also 'stromlosen Zustand transparent und emittieren erst bei Anlegen eines elektrischen Stroms das für die Anzeige des Warn- und/oder Informationshinweises erforderliche Licht. Eine außerdem mögliche Ausführungsform realisiert die Anzeigeelemente als ELD (Elektro-Luminiszenz-Display) . Dabei ist die Signalisiervorrichtung als EL-Folie ausgebildet, die beispielsweise auf der Fahrzeuginnenseite an der Fahrzeugscheibe als einfache aber wirkungsvolle Ausführungsform aufgebracht wird. In beiden Fällen dieser aktiven selbstleuchtenden Anzeigeelemente gilt ebenfalls der oben genannte Vorteil im Hinblick auf die Leitungsführung.In a preferred embodiment, the display elements can be designed as TOLED (Transparent Organic Light Emitting Device). These organic displays are transparent when they are deactivated, that is to say when they are de-energized, and only emit the light required for displaying the warning and / or information notice when an electrical current is applied. Another possible embodiment realizes the display elements as ELD (electro-luminescence display). The signaling device is designed as an EL film, which is applied, for example, on the inside of the vehicle to the vehicle window as a simple but effective embodiment. In both cases of these active self-illuminating display elements, the above-mentioned advantage with regard to the cable routing also applies.
Grundsätzlich ist es auch denkbar, dass die Strukturen derart ausgebildet sind, dass sie auch eine Filterwirkung für bestimmte Wellenlängen aufweisen. Durch die Anordnung einer entsprechenden Anzahl von Strukturen in der Fahrzeugscheibe kann somit eine Abschirmung des Fahrzeuginneren gegenüber thermischer Einstrahlung und dergleichen bewirkt werden.In principle, it is also conceivable that the structures are designed such that they also have a filter effect for certain wavelengths. By arranging an appropriate number of structures in the vehicle window, the interior of the vehicle can be shielded from thermal radiation and the like.
Eine weitere Ausführungsform sieht vor, dass die Sichtbarmachung eines Warn- und/oder Informationshinweises mit der Abgabe eines akustischen Warn- und/oder . Informationshinweises gekoppelt ist. Durch eine solche Koppelung ergibt sich der Vorteil, dass der Fahrzeuglenker auch dann gewarnt wird, wenn er gerade nicht auf die Fahrzeugscheibe blickt, sondern durch irgendwelche Ereignisse vom Verkehrsgeschehen abgelenkt ist.A further embodiment provides that the visualization of a warning and / or information notice with the delivery of an acoustic warning and / or. Information note is coupled. Such a coupling has the advantage that the vehicle driver is warned even when he is not looking at the vehicle window but is distracted from the traffic situation by any events.
In einer dritten wesentlichen Ausführungsform wird eine Signalisiervorrichtung zur Abgabe von Warn- und/oder Informationshinweisen in Fahrzeugen vorgeschlagen, die eine akustische Signaisquelle umfasst, welche sich dadurch auszeichnet, dass ein Warn- und/oder Informationshinweis mittels der Signalquelle derart ausgesendet wird, dass dieser eine Information über die Richtung enthält, die im Zusammenhang mit einem von Detektionsmitteln zur Erfassung der Umgebung des Fahrzeugs detektierten Objekt- steht, auf welches mittels des akustischen Warn- und/oder Informationshinweis aufmerksam gemacht wird.In a third essential embodiment, a signaling device for issuing warning and / or information notices in vehicles is proposed, which comprises an acoustic signal source, which is characterized in that a warning and / or information note is transmitted by means of the signal source in such a way that it signals one Contains information about the direction which is associated with an object detected by detection means for detecting the surroundings of the vehicle, which is pointed out by means of the acoustic warning and / or information note.
Auch hier ist, wie bei den optischen Signalisiervorrichtungen, die Zusatzinformation des Richtungshinweises eine deutliche Verbesserung beim Betrieb eines Fahrzeugs, indem die Aufmerksamkeit des Fahrzeugslenkers gleich in die Richtung gelenkt wird, in welcher ein das Verkehrsgeschehen gegebenenfalls beeinflussendes Ereignis durch ein Objekt zu erwarten ist.Here too, as with the optical signaling devices, the additional information in the directional information is a significant improvement in the operation of a vehicle, in that the driver's attention is immediately directed in the direction in which an event possibly influencing the traffic situation is to be expected by an object.
Eine besondere Ausführungsform kann so realisiert werden, dass die Information über die Richtung des Ereignisses, auf welches aufmerksam gemacht wird, durch selektive Abgabe eines akustischen Signals aus wenigstens einer von mehreren am Fahrzeug räumlich verteilt angeordneten Signalquellen erfolgt. Beispielsweise kann dazu ein akustisches Signal an einer Stelle des Fahrzeugs abgegeben werden, in dessen Richtung sich das detektierte Objekt befindet, beispielsweise rechts vorne.A special embodiment can be implemented in such a way that the information about the direction of the event, to which attention is drawn, is provided by selective delivery of an acoustic signal from at least one of a plurality of signal sources arranged spatially distributed on the vehicle. For this purpose, for example, an acoustic signal can be emitted at a point in the vehicle in the direction of which the detected object is located, for example at the front right.
In einer demgegenüber abgewandelten Ausführungsform soll die Information über die Richtung, in der das Objekt detektiert wird, durch eine Sprachausgabe aus einer Signalquelle erfolgen. Eine. zusätzliche vorteilhafte Möglichkeit bietet die Kombination mit dem vorigen Ausführungsbeispiel. Dazu wird von einer bestimmten Stelle des Fahrzeugs auch noch durch eine verbale Angabe die Richtung des detektieren Objektes bekannt gegeben, um die Aufmerksamkeit des Fahrzeuglenkers auf das detektierte Objekt zu richten. Dadurch ist eine räumliche Signalwirkung möglich, und der Fahrzeuglenker richtet seine Aufmerksamkeit intuitiv in die entsprechende Richtung.In an embodiment modified from this, the information about the direction in which the object is detected is to be output by a voice output from a signal source respectively. A. the combination with the previous exemplary embodiment offers an additional advantageous possibility. For this purpose, the direction of the detected object is also given from a specific point in the vehicle by verbal information in order to direct the driver's attention to the detected object. This enables a spatial signal effect and the driver intuitively directs his attention in the corresponding direction.
Vorteilhafterweise kann eine solche Signalquelle ein Lautsprecher der üblicherweise in Fahrzeugen vorhandenen Radio- und/oder Musikanlage sein.Such a signal source can advantageously be a loudspeaker of the radio and / or music system usually present in vehicles.
Eine zusätzliche Ausführungsform kann so "verwirklicht- erden, dass der Warn- und/oder Informationshinweis eine Abstandsinformation in Bezug auf das Ereignis erhält, auf welches hingewiesen wird. Dadurch ist es möglich, dem Fahrzeuglenker mitzuteilen, ob das gegebenenfalls verkehrsbeeinflussende Ereignis durch das detektierte Objekt unmittelbar bevor steht, oder ob noch eine gewisse Zeit bis zum Auftreten des Ereignisses vergeht.An additional embodiment can be implemented in such a way that the warning and / or information notice receives distance information in relation to the event to which reference is made. This makes it possible to inform the driver of the vehicle whether the event that may be influencing traffic is caused by the detected object is imminent, or whether a certain time elapses before the event occurs.
Denkbar sind dazu auch stufenweise Abstandsinformationen wie beispielsweise sehr nahe, nahe oder noch ausreichend entfernt. Eine solche Signalisierung kann beispielsweise durch die Höhe der Frequenz angezeigt werden, wobei vorteilhafterweise die Erhöhung der Frequenz mit der Annäherung des Ereignisses einhergeht, so dass intuitiv der Fahrer erkennt, ob er sofort oder erst später mit dem Objekt zu rechnen hat.In addition, step-by-step distance information such as, for example, very close, close or still sufficiently distant is also conceivable. Such signaling can be indicated, for example, by the level of the frequency, the increase in frequency advantageously being associated with the approach of the event, so that the driver intuitively recognizes whether he has to reckon with the object immediately or only later.

Figur 6 eine schematische Darstellung einer Signalisiervorrichtung zur kombinierten Abgabe eines optischen und eines akustischen Warn- und/oder Informationshinweises ..Figure 6 is a schematic representation of a signaling device for the combined delivery of an optical and an acoustic warning and / or information notice.
Die Figur 1 zeigt schematisch eine Signalisiervorrichtung 1 mit einer Fahrzeugscheibe 2 und darin verteilt angeordneten Anzeigeelementen 4 in der Draufsicht, sowie einen vergrößerten Detailausschnitt 10 eines in der Fahrzeugscheibe 2 angeordneten Anzeigeelementes 4a in geschnitten dargestellter Seitenansicht.FIG. 1 schematically shows a signaling device 1 with a vehicle window 2 and display elements 4 arranged therein distributed in plan view, as well as an enlarged detail 10 of a display element 4a arranged in vehicle window 2 in a sectional side view.
Der rechte Teil der Figur 1 zeigt die Draufsicht auf die Fahrzeugscheibe 2, bei der über einen wesentlichen Teil 3 Anzeigeelemente 4 verteilt angeordnet sind. Lediglich das Anzeigeelement 4a ist aktiv. Dazu wird, ausgehend von einer Lichtquelle 7, ein Lichtstrahl 6 mittels eines Lichtleiters 5 an das Anzeigeelement 4 gelenkt, welches aufgrund der Bestrahlung durch den Lichtstrahl für den Fahrzeuglenker sichtbar wird. Die übrigen Anzeigeelemente 4 sind für den Fahrzeuglenker nicht sichtbar.The right part of FIG. 1 shows the top view of the vehicle window 2, in which an essential part 3 Display elements 4 are arranged distributed. Only the display element 4a is active. For this purpose, starting from a light source 7, a light beam 6 is directed to the display element 4 by means of a light guide 5, which is visible to the vehicle driver due to the radiation by the light beam. The remaining display elements 4 are not visible to the vehicle driver.
Dazu sind die Strukturen 9 im Anzeigeelement 4 so klein, dass sie im nicht beleuchteten Zustand vom menschlichen Auge nicht gesehen werden können.For this purpose, the structures 9 in the display element 4 are so small that they cannot be seen by the human eye in the non-illuminated state.
Das Gleiche gilt für die Lichtleiter 5. Diese sind aber auch während der Durchleitung des ' Lichtstrahles aufgrund ihrer' lichteinschließenden Eigenschaft für den Fahrzeuglenker unsichtbar.The same applies to the light guide 5. However, these are also invisible to the vehicle driver during the passage of the ' light beam due to their' light-enclosing property.
Ausgehend vom sichtbaren Anzeigeelement 4a ist der Detailausschnitt 10 zum linken Bereich in der Figur 1 hin dargestellt. Die Vergrößerung des für den Fahrzeuglenker 8 sichtbaren Anzeigeelementes 4 zeigt den Verlauf des von der Lichtquelle 7 erzeugten und vom Lichtleiter 5 an das Anzeigeelement 4 geführten und von diesem in Richtung des Fahrzeuglenkers durch die Struktur 9 reflektierten Lichtstrahls 6.Starting from the visible display element 4a, the detail section 10 is shown towards the left area in FIG. 1. The enlargement of the display element 4 visible to the vehicle driver 8 shows the course of the light beam 6 generated by the light source 7 and guided by the light guide 5 to the display element 4 and reflected by the structure 9 in the direction of the vehicle driver.
Die Fahrzeugscheibe 2 ist in diesem Fall als zweiteilige Verbundglasscheibe ausgebildet, zwischen deren beiden Teilen 2 , 2 sowohl die Anzeigeelemente 4 als auch die Lichtleiter 5 angeordnet sind. Die Proportionen in der Zeichnung sind nicht maßstabsgetreu, es handelt sich lediglich um eine Beispielsdarstellung. Eine solche Anordnung ist möglich aber nicht notwendigerweise erforderlich. Es kann durchaus auch vorgesehen sein, dass die Signalisiervorrichtung außen an der Scheibe angeordnet ist. Vorteilhafterweise .wird sie dabei an der dem Fahrgastinnenraum zugewandten Seite der Scheibe angeordnet um gegen äußere Einflüsse geschützt zu sein. Die für die Lichtleiter 5 wesentliche Ebene 21 der Fahrzeugscheibe 2 ist in der Figur 1 durch strichpunktierte Linien angezeigt.In this case, the vehicle window 2 is designed as a two-part laminated glass window, between the two parts 2, 2 of which both the display elements 4 and the light guide 5 are arranged. The proportions in the drawing are not to scale, it is only an example. Such an arrangement is possible but not necessarily necessary. It can also be provided that the signaling device is arranged on the outside of the pane. It is advantageously arranged on the side of the window facing the passenger interior in order to be protected against external influences. The plane 21 of the vehicle window 2 that is essential for the light guides 5 is indicated in FIG. 1 by dash-dotted lines.
Die Figur 2 zeigt eine schematische Darstellung einer Signalwirkung auf einen Fahrzeuglenker mit einem sichtbar gemachten Anzeigeelement 4. Dazu wird auf ein in Blickrichtung des Fahrzeuglenkers 8 hinter dem sichtbar gemachten Anzeigeelement 4a, vom Fahrzeug noch entfernten Objekt 11 aufmerksam gemacht, das als Ursache für ein gegebenenfalls das Verkehrsgeschehen beein lussendes Ereignis angezeigt wird.FIG. 2 shows a schematic representation of a signal effect on a vehicle driver with a display element 4 made visible. For this purpose, attention is drawn to an object 11 which is still removed from the vehicle in the direction of view of the vehicle driver 8 behind the display element 4a and which is possibly the cause of an the event affecting traffic is displayed.
An'de'r Fahrzeugscheibe 2 sind in diesem Fall' über deren' wesentlichen Teil 3 verteilt eine Vielzahl von Anzeigeelementen 4 angeordnet. Sie befinden sich an der dem Fahrgastraum zugewandten Oberfläche der Scheibe aufgebracht. Die Blickrichtung 13 des Fahrzeuglenkers 8 auf das Objekt 11 liegt innerhalb seines bei normalem Verkehrsgeschehen üblichen vertikalen und horizontalen Blickfeldes 12. Durch die Sichtbarmachung des Anzeigeelementes 4a als eines von vielen ansonsten nicht sichtbaren Anzeigeelementen 4 wird nun die Aufmerksamkeit des Fahrzeuglenkers in die Richtung gelenkt, aus welcher ihm das Objekt 11 entgegenkommt.Are to 'de' r vehicle wheel 2 in this case, 'over their "essential part 3 distributed a plurality of display elements 4 are arranged. They are applied to the surface of the window facing the passenger compartment. The line of sight 13 of the vehicle driver 8 towards the object 11 lies within its vertical and horizontal field of view 12 which is normal in normal traffic conditions. By making the display element 4a visible as one of many otherwise invisible display elements 4, the driver's attention is now directed in the direction which comes towards him object 11.
Die Darstellungen der Figuren 3 bis 5 zeigen wiederum über den wesentlichen Teil 3 der Fahrzeugscheibe 3 verteilt angeordnete Anzeigeelemente 4, 4a mit zum Teil anderen, ebenfalls fest vorgegebenen geometrischen Formen. Ein weiterer Unterschied dieser Darstellungen liegt in der Ausführungsform der einzelnen Elemente. In Figur 3 sind die Anzeigeelemente 4 als TOLED ausgebildet. Lediglich das linke Element 4a ist durch Beaufschlagung mit elektrischem Strom sichtbar. Alle anderen Elemente und auch die Zuleitungen 14 sind in gestrichelter Darstellung als vom menschlichen Auge nicht sichtbare Strukturen gezeigt. Das Anzeigeelement 4 bzw. 4a ist in dieser Darstellung als Warndreieck wiedergegeben. Selbstverständlich sind aber auch andere Ausführungsformen denkbar.The illustrations in FIGS. 3 to 5 in turn show display elements 4, 4a, which are distributed over the essential part 3 of the vehicle window 3, with partly different, likewise predetermined geometric shapes. Another difference between these representations lies in the embodiment of the individual elements. In Figure 3, the display elements 4 are designed as TOLED. Only the left element 4a is visible when it is subjected to electrical current. All other elements and also the supply lines 14 are shown in broken lines as structures not visible to the human eye. The display element 4 or 4a is shown in this representation as a warning triangle. Of course but other embodiments are also conceivable.
Die Figur 4 zeigt eine Ausführungsform mittels einer Elektroluminiszenzfolie. Das Anzeigeelement 4a wird hier durch die Aktivierung der Elektroluminiszenzeigenschaft des ansonsten nicht sichtbaren Anzeigeelementes 4 sichtbar gemacht. Auch in dieser Darstellung sind die Zuleitungen 14 sowie die nicht sichtbaren Anzeigeelemente 4 gestrichelt dargestellt.FIG. 4 shows an embodiment using an electroluminescent film. The display element 4a is made visible here by activating the electroluminescent property of the otherwise invisible display element 4. The supply lines 14 and the non-visible display elements 4 are also shown in dashed lines in this illustration.
Die Figur 5 zeigt wiederum über einen wesentlichen Teil 3 der Fahrzeugscheibe 2 verteilt angeordnete Anzeigeelemente 4, 4a, die in diesem Fall als Hologramme ausgebildet sind. Diese unter gewöhnlichen Lichteinflüssen nicht sichtbaren Hologramme werden mittels eines von einem Laser 15 erzeugten Laserstrahl 16 mit einer auf das Hologramm abgestimmten Wellenlänge angestrahlt und dadurch für den Fahrzeuglenker sichtbar gemacht. Vorzugsweise sind die Anzeigeelemente 4 als diffus reflektierende Hologramme ausgebildet, so dass die Aktivierung durch den Laserstrahl 16 auch dann gewährleistet ist, wenn der Winkel für die Einstrahlung des Laserstrahls 16 auf das Anzeigeelement 4 nicht optimal ist.FIG. 5 again shows display elements 4, 4a distributed over an essential part 3 of the vehicle window 2, which in this case are designed as holograms. These holograms, which are not visible under normal light influences, are illuminated by means of a laser beam 16 generated by a laser 15 with a wavelength matched to the hologram and thereby made visible to the vehicle driver. The display elements 4 are preferably designed as diffusely reflecting holograms, so that activation by the laser beam 16 is also ensured when the angle for the irradiation of the laser beam 16 on the display element 4 is not optimal.
Die Figur 6 zeigt eine Ausführungsform einerFIG. 6 shows an embodiment of a
Signalisiervorrichtung bei der sowohl eine optische als auch eine akustische Warnung für den Fahrzeuglenker generiert wird. In der Draufsicht auf das Fahrzeug wird in der Mitte der Fahrzeugscheibe 2, also vom Fahrzeuglenker 8 aus gesehen rechts vorne ein Anzeigeelement 4a sichtbar gemacht. Dieses lenkt die Aufmerksamkeit des Fahrzeuglenkers auf ein Objekt 11, welches sich rechts vor dem Fahrzeug befindet und wobei in diesem Fall eine Bewegungsrichtung 19 in Richtung vor das Fahrzeug vermutet wird, welches sich seinerseits mit der Bewegungsrichtung 20 fortbewegt.Signaling device in which both an optical and an acoustic warning are generated for the vehicle driver. In the top view of the vehicle, a display element 4a is made visible in the center of the vehicle window 2, that is to say seen from the vehicle driver 8, at the front right. This directs the driver's attention to an object 11 which is located to the right in front of the vehicle and in which case a direction of movement 19 in the direction in front of the vehicle is assumed, which in turn moves with the direction of movement 20.
Zusätzlich zum optischen Warn- und/oder Informationshinweis erfolgt ein akustisches Signal 18 aus einer akustischen Signalquelle 17, in diesem Fall einem-- Lautsprecher der Musikoder Radioanlage des Fahrzeugs, rechts vorne im Fahrzeug. Dadurch wird die Aufmerksamkeit des Fahrzeuglenkers sowohl optisch als auch akustisch in die Richtung des Objektes 11 gelenkt . In addition to the visual warning and / or information notice, an acoustic signal 18 is emitted from an acoustic signal Signal source 17, in this case a loudspeaker of the vehicle's music or radio system, in the front right of the vehicle. As a result, the driver's attention is drawn both optically and acoustically in the direction of the object 11.
