Optische Warnvorrichtung zur Verwendung bei StraßenfahrzeugenOptical warning device for use on road vehicles

Die Neuerung bezieht sich auf eine optische Warnvorrichtung zur Verwendung bei Straßenfahrzeugen. The innovation relates to an optical warning device for use in road vehicles.

Viele Straßenunfälle, wie z.B. Auffahrunfälle auf Autobahnen bei plötzlichem Nebel oder plötzlicher Glätte ließen sich durch eine aktuelle Warnung der Verkehrsteilnehmer u.U. vermeiden. Many road accidents, such as rear-end collisions on motorways in the event of sudden fog or sudden slippery conditions, could possibly be avoided by providing timely warnings to road users.

Aufgabe der Neuerung ist es, eine Vorrichtung aufzuzeigen, mit der bei gefährlichen Verkehrssituationen und/oder Straßenverhältnissen usw. eine Warnung der Verkehrsteilnehmer möglich ist. Zur Lösung dieser Aufgabe ist eine Vorrichtung entsprechend dem Schutzanspruch 1 ausgebildet.The aim of the innovation is to demonstrate a device with which it is possible to warn road users in dangerous traffic situations and/or road conditions, etc. To solve this problem, a device is designed in accordance with protection claim 1.

Mit der neuerungsgemäßen Vorrichtung, die bevorzugt an großen Straßenfahrzeugen, wie LKW oder Bussen vorgesehen wird, können entgegenkommende Verkehrsteilnehmer vor einer gefährlichen Verkehrssituation durch Einschalten des wenigstens einen Anzeige-Displays der Warnvorrichtung rechtzeitig gewarnt werden, beispielsweise vor Nebelbänken, Straßenglätte, Staus usw.. Das wenigstens eine Anzeige-Display ist hierbei möglichst hoch derart befestigt, daß es für den Gegenverkehr gut sichtbar ist.With the new device, which is preferably provided on large road vehicles such as trucks or buses, oncoming road users can be warned in good time of a dangerous traffic situation by switching on at least one display of the warning device, for example of fog banks, slippery roads, traffic jams, etc. The at least one display is attached as high as possible so that it is clearly visible to oncoming traffic.

Weiterbildungen der Neuerung sind Gegenstand der Unteransprüche. Die Neuerung wird im Folgenden an einem Ausführungsbeispiel näher erläutert. Es zeigen:Further developments of the innovation are the subject of the subclaims. The innovation is explained in more detail below using an example. They show:

Fig. 1 in vereinfachter Darstellung eine Frontansicht eines LKW; Fig. 2 ein Block- oder Funktionsdiagramm der neuerungsgemäßen Vorrichtung; Fig. 3 in vereinfachter Darstellung einen Teilschnitt durch ein Anzeigendisplay.Fig. 1 shows a simplified front view of a truck; Fig. 2 shows a block or functional diagram of the device according to the innovation; Fig. 3 shows a simplified partial section through a display.

In den Figuren ist 1 ein LKW üblicher Bauart, von dem in der Fig. 1 u.a. das Fahrerhaus 2 und ein auf dem Dach des Fahrerhauses montiertes Luftleitschild 3 dargestellt sind. Auf dem DachIn the figures, 1 is a truck of a conventional design, of which the driver's cab 2 and an air deflector 3 mounted on the roof of the driver's cab are shown in Fig. 1. On the roof

4:4:

j des Fahrerhauses 2 befindet sich weiterhin ein Anzeigen-Display 4 der erfindungsgemäßen * Vorrichtung. j of the driver's cab 2 there is also a display screen 4 of the device according to the invention *.

Eine Ausführungsform dieser Vorrichtung ist in der Fig. 2 im Prinzip wiedergegeben. Sie besteht im wesentlichen aus dem elektrisch betriebenen Anzeigen-Display 4, aus einem dieses Anzeige-Display ansteuernden Generator 5 und einem manuell betätigbaren Signalgeber oder Auslöser 6, der beispielsweise von einem Taster gebildet ist und im Fahrerhaus 2 derart angeordnet ist, daß dieser Signalgeber bequem vom Fahrersitz aus betätigt werden kann.An embodiment of this device is shown in principle in Fig. 2. It consists essentially of the electrically operated display 4, a generator 5 that controls this display and a manually operated signal generator or trigger 6, which is formed, for example, by a button and is arranged in the driver's cab 2 in such a way that this signal generator can be conveniently operated from the driver's seat.

Der Generator bzw. die Ansteuerschaltung 5 ist so ausgeführt, daß sie nach dem Betätigen des .Signalgebers 6 für eine vorgegebene Zeitperiode der Anzeige-Display 4 einschaltet bzw. aktiviert, und zwar zur Abgabe eines optischen Warnsignals, vorzugsweise zur Abgabe eines blinkenden optischen Warnsignals in Form eines Bildes oder Symbols auf der vom Display gebildeten Bildfläche. Das Anzeige-Display 4 besteht hierfür, wie in der Fig. 3 angedeutet ist, aus einer Vielzahl von Leuchtdiodenoder anderen Licht emittierenden, elektrisch ansteuerbaren Elementen 7, die hinter einer aus lichtdurchlässigem bzw. translizentem Material bestehenden Scheibe 8 angeordnet sind, und zwar in mehreren horizontalen Zeilen, wobei jede der in vertikaler Richtung aufeinanderfolgenden Zeilen eine Vielzahl von Elementen 7 aufweist. Die Scheibe 8 ist an ihrer Außenseite optisch so ausgebildet, daß sich eine Bündelung des austretenden Lichtes nach vorne ergibt, wie dies mit den Strahlen 9 in der Fig. 3 angedeutet ist.The generator or the control circuit 5 is designed in such a way that after the signal generator 6 is actuated, it switches on or activates the display 4 for a predetermined period of time, specifically to emit an optical warning signal, preferably to emit a flashing optical warning signal in the form of an image or symbol on the image area formed by the display. The display 4 consists for this purpose, as indicated in Fig. 3, of a large number of light-emitting diodes or other light-emitting, electrically controllable elements 7, which are arranged behind a disc 8 made of transparent or translucent material, specifically in several horizontal rows, with each of the rows following one another in the vertical direction having a large number of elements 7. The disc 8 is optically designed on its outside in such a way that the emerging light is bundled forwards, as indicated by the rays 9 in Fig. 3.

Durch entsprechende farbliche und/oder graphische Gestaltung oder aber durch entsprechende farbliche Gestaltung der Licht emittierenden Elemente ist erreicht, daß bei eingeschaltetem Display 4 dort ein hell leuchtendes, auf eine mögliche Gefahr hindeutendes Symbol beispielsweise ein Dreieck in roter Farbe auf einem weißen, leuchtenden Untergrund erscheint, welches in dem vom Generator 5 bestimmten Takt blinkt. Der Generator 5 liefert hierfür eine in ihrer Amplitude sich ändernde Spannung zur Ansteuerung des Displays 4 bzw. der dortigen Elemente 7. Da das Anzeige-Display 4 auf dem Dach des Fahrerhauses 2 des LKW 1 angeordnet ist, ist dieses Anzeige-Display 4 für entgegenkommende Fahrzeuge weithin sichtbar.By means of appropriate color and/or graphic design or by means of appropriate color design of the light-emitting elements, it is achieved that when the display 4 is switched on, a brightly lit symbol indicating a possible danger appears, for example a red triangle on a white, luminous background, which flashes at the rate determined by the generator 5. The generator 5 supplies a voltage that changes in amplitude to control the display 4 or the elements 7 there. Since the display 4 is arranged on the roof of the driver's cab 2 of the truck 1, this display 4 is clearly visible to oncoming vehicles.

A18113.DOCA18113.DOC

Wird von dem mit dieser Vorrichtung ausgestatteten LKW 1 eine Gefahrenquelle, beispielsweise ein Stau, Nebelbildung oder eine andere gefährliche Verkehrssituation bemerkt, die den Gegenverkehr betrifft, so kann durch Einschalten des Anzeige-Displays 4 bzw. durch den dann blinkenden Warnhinweis auf diese Gefahrenquelle frühzeitig aufmerksam gemacht werden.If the truck 1 equipped with this device notices a source of danger, for example a traffic jam, fog or another dangerous traffic situation that affects oncoming traffic, this source of danger can be alerted to early by switching on the display 4 or by the warning message then flashing.

Es versteht sich, daß das Anzeige-Display 4 auch anders, als vorstehend beschrieben, ausgeführt sein kann. In jedem Fall wird aber dieses Anzeige-Display so ausgeführt, daß es vom Fahrersitz aus zur Abgabe des optischen Warnsignals eingeschaltet bzw. aktiviert werden kann. Weiterhin kann die Vorrichtung selbstverständlich nicht nur in einem LKW, sondern auch an anderen Straßenfahrzeugen, beispielsweise an Bussen, vorgesehen werden, wobei auch die Anordnung des Anzeige-Displays 4 abweichend von der vorstehend beschriebenen Anordnung sein kann, beispielsweise an bzw. hinter der Windschutzscheibe des LKW oder des Busses. Bevorzugt sollte das Anzeige-Display 4 aber möglichst hoch angeordnet werden, daß der optische Warnhinweis möglichst weit sichtbar ist.It goes without saying that the display 4 can also be designed differently than described above. In any case, however, this display is designed in such a way that it can be switched on or activated from the driver's seat to emit the optical warning signal. Furthermore, the device can of course be provided not only in a truck, but also on other road vehicles, for example on buses, whereby the arrangement of the display 4 can also differ from the arrangement described above, for example on or behind the windshield of the truck or bus. Preferably, however, the display 4 should be arranged as high as possible so that the optical warning is visible from as far as possible.
