Description

Anzeigeeinrichtung zur optischen Warnung vor Radfahrern  Display device for visual warning against cyclists
beim Abbiegen von einer Haupt- in eine Nebenstraße Die Erfindung betrifft eine Anzeigeeinrichtung zur optischen Warnung eines von einer Hauptstraße in eine Nebenstraße abbiegenden Autofahrers vor einer sich der Nebenstraße parallel zur Hauptstraße annähernden Person, mit wenigstens einem Sensor zum Erfassen der Person und wenigstens einer bei Annäherung einer Person ein optisches Warnsignal abgebenden Leuchte.  The invention relates to a display device for optically warning a driver turning from a main road to a side road in front of a person approaching the side road parallel to the main road, with at least one sensor for detecting the person and at least one approaching person a person emitting an optical warning light emitting lamp.
Fig. 1 zeigt solch eine typische Verkehrs Situation beim Abbiegen an einer Kreuzung von einer Hauptstraße in eine Nebenstraße in einer schematischen Draufsicht. Insbesondere zeigt Fig. 1 eine Hauptstraße HS mit einer unter Ausbildung einer Kreuzung sich rechtwinklig zur Hauptstraße HS erstreckenden Nebenstraße NS. Für den Zweck dieser Beschreibung dienen die Begriffe„Hauptstraße" und„Nebenstraße" lediglich der Unterscheidung der Straßen, stellen aber nicht zwingend eine Vorrangigkeit der einen Straße vor der anderen Straße dar. Fig. 1 shows such a typical traffic situation when turning at an intersection from a main road to a side street in a schematic plan view. In particular, FIG. 1 shows a main road HS with a secondary road NS extending at right angles to the main road HS, forming an intersection. For the purposes of this description, the terms "main road" and "side road" are used merely to distinguish the roads, but are not necessarily a priority of one road in front of the other road.
Zur Regelung des Verkehrsflusses sind im Kreuzungsbereich an der Hauptstraße HS und an der Nebenstraße NS mehrere Lichtsignalanlagen LSA installiert, die ein gefahrloses To regulate the traffic flow several traffic signal systems LSA are installed in the crossing area on the main road HS and on the side road NS, which is a safe
Abzweigen von der Hauptstraße HS in die Nebenstraße und/oder von der Nebenstraße NS in die Hauptstraße ermöglichen. Branching off the main road HS into the side road and / or from the side road NS into the main road.
Des Weiteren sind zwei Autos bzw. Autofahrer AI, A2 dargestellt, die sich auf der Furthermore, two cars or motorists AI, A2 are shown on the
Hauptstraße HS befinden, wobei der eine Autofahrer AI im Begriff ist, von der Hauptstraße HS in die Nebenstraße NS einzubiegen. Main road HS are, with the one driver AI is about to turn from the main road HS in the side road NS.
Der Abbiegevorgang des Autofahrers A2 ist insofern gefahrträchtig, dass parallel zur The turning process of the driver A2 is dangerous in that parallel to
Hauptstraße HS ein die Nebenstraße NS kreuzender Radweg RW verläuft, der von den Radfahrern Rl, R2, R3 verwendet wird. Main road HS a wheel path RW crossing the side road NS, which is used by the cyclists Rl, R2, R3.
Während der Autofahrer AI die in Fahrtrichtung vor ihm liegenden Radfahrer R2, R3 während des Abbiegens beobachten und durch eine an deren Bewegung angepasste Fahrweise berücksichtigen kann, bewegt sich der für den Autofahrer AI entgegen seiner Fahrtrichtung zurückliegende Radfahrer Rl außerhalb dessen üblichen Blickfelds und bleibt daher beim Abbiegevorgang unbeachtet. Selbst bei Ausführung eines entgegen der Fahrtrichtung schwenkenden Schulterblicks mag ein sich schnell in Fahrtrichtung bewegender Radfahrer Rl nicht wahrgenommen werden, sodass es zu einer Kollision zwischen dem Autofahrer AI und dem Radfahrer Rl kommen kann. While the driver AI watching in the direction of travel in front of him cyclists R2, R3 while turning and consider by adapted to their movement driving, moves for the driver AI against its direction of travel past cyclists Rl outside its usual field of vision and therefore remains unnoticed when turning. Even when executing a shoulder view that pivots counter to the direction of travel, a cyclist Rl moving rapidly in the direction of travel may not be perceived, so that a collision can occur between the driver AI and the cyclist Rl.
Um diese Gefahrensituation möglichst zu vermeiden und entsprechende Unfälle zu verhindern, ist aus der EP 2 462 574 Bl bereits eine Lichtsignalanlage bekannt, die mit einem gegen die Fahrtrichtung des zu regelnden Verkehrs ausgerichteten Sensor ausgestattet ist, der eine in Fahrtrichtung gesehen rechts neben einem Fahrzeug sich der Lichtsignalanlage annähernde Person erkennt und darauf ansprechend das Aufleuchten oder Blinken einer zu dem grünen Signallicht benachbart angeordneten vierten Signallichts bewirkt. In order to avoid this dangerous situation as far as possible and to prevent corresponding accidents, EP 2 462 574 B1 already discloses a traffic light system which is equipped with a sensor oriented against the direction of travel of the traffic to be controlled, which, seen in the direction of travel, is located to the right of a vehicle the light signal system recognizes approaching person and responsively causes the lighting or flashing of a signal light adjacent to the adjacent arranged fourth signal light.
Wenngleich diese Idee grundsätzlich zur Vermeidung der oben genannten Unfälle geeignet ist, hat es sich in praktischen Versuchen herausgestellt, dass die Lichtsignalanlage zwar bei entfernter Annäherung an die Kreuzung noch wahrgenommen wird, jedoch - wenn die Ampel grün zeigt - bei weiterer Annäherung nicht weiter beachtet wird und zwischenzeitlich sich der Lichtsignalanlage annähernde, in diese Gefahrenzone eintretende Personen nicht viel besser geschützt sind. Although this idea is basically suitable for avoiding the abovementioned accidents, it has been found in practical experiments that the light signal system is still perceived when the approaching distance to the intersection is remote, but - if the traffic light turns green - is disregarded on further approach and in the meantime, the light signal system approaching, entering this danger zone people are not much better protected.
Aufgabe der Erfindung ist es daher, eine Anzeigeeinrichtung für den Schutz einer zur Überquerung einer Straße oder eines Weges ansetzenden Person im Bereich einer Kreuzung zu schaffen, die vom Autofahrer besser wahrgenommen werden kann. Diese Aufgabe wird erfindungsgemäß durch die Anzeigeeinrichtung mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder. The object of the invention is therefore to provide a display device for the protection of a person starting for crossing a road or a road person in the area of an intersection, which can be better perceived by the driver. This object is achieved by the display device with the features of claim 1. The subclaims reflect advantageous embodiments of the invention.
Grundgedanke der Erfindung ist es, eine Anzeigeeinrichtung bereit- und so aufzustellen, dass diese während des Abbiegevorgangs vom Autofahrer wahrgenommen werden kann. The basic idea of the invention is to provide a display device and to set it up so that it can be perceived by the driver during the turn-off process.
Erfindungsgemäß ist die Anzeigeeinrichtung für den abbiegenden Autofahrer so ausgerichtet, dass dieser das von der Anzeigeeinrichtung abgegebene Lichtzeichen beim Abbiegevorgang selbst, d.h. während des Einbiegens von der Hauptstraße in die Nebenstraße sehen kann. Hierfür ist die Anzeigeeinrichtung in Fahrtrichtung eines auf der Hauptstraße fahrenden Autofahrers im Kreuzungsbereich mit der Nebenstraße vor der Nebenstraße, also auf der Innenseite der vom Autofahrer zu beschreibenden Kurve, angeordnet und so eingerichtet, dass der Ab strahl winkel der Anzeigeeinrichtung in den Kreuzungsbereich in einem Bereich zwischen einer quer zum Straßenverlauf der Hauptstraße verlaufenden ersten Achse und einer quer zum Straßenverlauf der Nebenstraße verlaufenden zweiten Achse liegt. Die According to the display device for the turning motorist is oriented so that it can see the emitted light from the display device during the turning process itself, ie during the turning of the main road in the side street. For this purpose, the display device in the direction of travel on the main road motorist in the crossing area with the side street in front of the side street, ie on the inside of the driver to be described curve, arranged and set up so that the beam angle of the display device in the crossing area in one area between a first axis extending transversely to the road of the main road and a second axis running transversely to the road of the minor road. The
Anzeigeeinrichtung befindet sich während des Abbiegevorgangs bei Rechtsverkehr also stets rechts vom Autofahrer (bei Linksverkehr entsprechend links vom Autofahrer) und strahlt von der Innenseite der Kurve im Wesentlichen quer zur Fahrtrichtung des abbiegenden Fahrzeugs ab. Insbesondere strahlt die Anzeigeeinrichtung in einen Bereich hinter einer vor der Display device is during the turn-off for right-hand traffic so always right of the driver (in left-hand traffic corresponding to the left of the driver) and radiates from the inside of the curve substantially transverse to the direction of travel of the turning vehicle. In particular, the display device radiates into an area behind a front of the
Abzweigung aufgestellten Lichtsignalanlage ab, die vom abbiegenden Autofahrer erkannt werden kann. Hingegen wird ein Autofahrer, der sich auf der Hauptstraße befindet und nicht in die Abzweigung set up traffic lights, which can be detected by the turning motorist. On the other hand, a driver who is on the main road and not in the
Nebenstraße einbiegen will, die Anzeigeeinrichtung nicht wahrnehmen, da dessen Blick in Richtung des Verlaufs der Hauptstraße ausgerichtet ist, in die im Wesentlichen auch die Anzeigeeinrichtung abstrahlt. War es nach dem Stand der Technik zuvor nicht möglich, den abbiegenden Autofahrer vor einer herannahenden Person zu warnen, wenn dieser die vor der Abzweigung aufgestellte Lichtsignalanlage passiert hat, erscheint die erfindungsgemäße Anzeigeeinrichtung jetzt beim Schulterblick unmittelbar im Gesichtsfeld des Autofahrers, sodass eine Warnung problemlos wahrgenommen werden wird. Da erfindungsgemäß eine sich im„toten Winkel" des  Side street wants to turn, do not perceive the display device, since its view is aligned in the direction of the course of the main street, in which essentially emits the display device. It was not previously possible according to the prior art to warn the turning motorist from an approaching person, if this has passed the set up before the junction light signal system, the display device according to the invention now appears at shoulder glance directly in the driver's field of vision, so perceived a warning problem will be. Since according to the invention in the "blind spot" of the
Autofahrers bewegende Person durch die während des Abbiegevorgangs für den Autofahrer jederzeit sichtbare Anzeigeeinrichtung angezeigt wird, ist das Unfallrisiko beim Abbiegen erheblich gesenkt. Driver's moving person is displayed by the visible during the turn for the driver at any time display device, the accident risk when turning is significantly reduced.
Dabei ist die Anordnung der Anzeigeeinrichtung so gewählt, dass die erfindungsgemäße Anzeigeeinrichtung auf der Kurveninnenseite angeordnet ist, sodass der Autofahrer nicht etwa auf Lichtsignale oder Anzeigen (etwa auf der gegenüberliegenden Straßenseite) achten muss, die von der eigentlichen Gefahrenquelle ablenken. Die erfindungsgemäße Anzeigeeinrichtung ist insbesondere unabhängig von einer Lichtsignalanlage operabel und einsetzbar. Beispielsweise kann eine erfindungsgemäß ausgestaltete Anzeigeeinrichtung auch an Kreuzungen aufgestellt werden, an denen keine Lichtsignalanlagen installiert sind, sodass auch an Kreuzungen ohne Ampeln die Sicherheit für kreuzende Personen, insbesondere Radfahrern, vor dem abbiegenden Verkehr erhöht ist. Darüber hinaus sorgt eine erfindungsgemäß eingerichtete Anzeigeeinrichtung, die speziell als Inselsystem autark betrieben werden kann, für eine erhöhte Sicherheit bei der The arrangement of the display device is chosen so that the display device according to the invention is arranged on the inside of the curve, so that the driver does not have to pay attention to light signals or displays (for example on the opposite side of the road), which distract from the actual source of danger. The display device according to the invention is in particular operable and usable independently of a traffic signal system. For example, a display device designed according to the invention can also be set up at intersections where no traffic signal systems are installed, so that the safety for intersecting persons, especially cyclists, is increased in front of the intersecting traffic even at intersections without traffic lights. In addition, a display device configured according to the invention, which can be operated autonomously as an isolated system, provides for increased safety in the case of
Straßenüberquerung für den Fall, dass eine vorinstallierte Ampel ausfällt und die Road crossing in the event that a pre-installed traffic light fails and the
Verkehrssituation unter Umständen ohne Verkehrsregelung durch entsprechende Traffic situation under circumstances without traffic regulation by appropriate
Lichtsignalanlagen unübersichtlich ist. Traffic lights is confusing.
Erfindungsgemäß ist also eine Anzeigeeinrichtung bzw. eine Anordnung mit einer According to the invention, therefore, a display device or an arrangement with a
Anzeigeeinrichtung zur optischen Warnung eines von einer Hauptstraße in eine Nebenstraße abbiegenden Autofahrers vor einer (aus der Fahrtrichtung des Autofahrers auf der Hauptstraße kommenden) sich der Nebenstraße parallel zur Hauptstraße annähernden Person vorgesehen, mit wenigstens einem Sensor zum Erfassen der Person und wenigstens einer bei Annäherung einer Person ein optisches Warnsignal abgebenden Leuchte, deren Ab strahl winkel sich in den Kreuzungsbereich zwischen einer quer zum Straßenverlauf der Hauptstraße verlaufenden ersten Achse und einer quer zum Straßenverlauf der Nebenstraße verlaufenden zweiten Achse öffnend ausgerichtet ist. Die gedachten Achsen können beispielsweise jeweils im rechten Winkel zur Hauptstraße bzw. Nebenstraße verlaufen. Display device for optically warning a driver turning off a main road into a side street in front of a person (coming from the driver's direction on the main road) approaching the side street parallel to the main street, with at least one sensor for detecting the person and at least one approaching one Person an optical warning signal emitting luminaire whose beam angle is aligned in the crossing region between a transverse to the road course of the main road extending first axis and a transverse to the road course of the minor road extending second axis opening. The imaginary axes can, for example, each run at right angles to the main road or side road.
Die Begriffe„Hauptstraße" und„Nebenstraße" sollen für den Zweck der Beschreibung lediglich die Unterscheidung zwischen zwei Straßen und/oder Wegen deutlich machen. So kann es sich bei der„Nebenstraße" beispielsweise auch um eine Einfahrt oder Zufahrt zu einem Grundstück handeln, die von einem Fußgänger- oder Radweg gekreuzt wird, wobei die erfindungsgemäße Anzeigeeinrichtung im Kreuzungsbereich von Straße („Hauptstraße") und Einfahrt/Zufahrt („Nebenstraße") Verwendung findet. Bevorzugt ist der Ab strahl winkel der Leuchte selbst durch die erste Achse und die zweiteThe terms "main street" and "side street" are intended to make clear for the purpose of description only the distinction between two streets and / or paths. For example, the "secondary road" may also be a driveway or access road to a property that is crossed by a pedestrian or cycle path, wherein the display device according to the invention is located in the crossing area of the street ("main street") and the entrance / driveway (" Nebenstraße).) Preferably, the beam angle of the luminaire is itself determined by the first axis and the second
Achse begrenzt. Dadurch wird der gesamte gefahrenträchtige Bereich, in dem der Autofahrer ohnehin einen Schulterblick durchführen muss, so ausgeleuchtet, dass der Autofahrer das durch die Anzeige abgegebene Warnsignal wahrnimmt. Weiter bevorzugt ist die Anzeigeeinrichtung wenigstens teilweise als den Übergang von der Hauptstraße in die Nebenstraße begleitendes Geländer ausgebildet. Die Ausbildung der Anzeigeeinrichtung als Geländer hat den Vorteil, dass einerseits ein„Schneiden" der Kurve durch den Autofahrer verhindert, andererseits ein Schutz der sich hinter dem Geländer auf dem Radweg oder Fußgängerweg befindlichen Personen erzeugt wird. Dieses ist insbesondere an von LKW-Fahrern häufig befahrenen Kreuzungen von Vorteil. Axis limited. As a result, the entire hazardous area, in which the driver must anyway perform a shoulder view, is illuminated so that the driver perceives the warning signal emitted by the display. More preferably, the display device is at least partially formed as the transition from the main road to the side street accompanying railing. The design of the display device as a railing has the advantage that, on the one hand, the driver is prevented from "cutting" the curve, and, on the other hand, the protection of the persons located behind the railing on the cycle path or pedestrian path is created, which is particularly common among truck drivers used intersections of advantage.
Die wenigstens eine Leuchte ist speziell auf Höhe eines PKW -Fensters angeordnet, wobei die wenigstens eine Leuchte auch auf Höhe eines LKW-Fensters angeordnet sein kann. The at least one lamp is arranged especially at the height of a passenger car window, wherein the at least one lamp can also be arranged at the height of a truck window.
Besonders bevorzugt sind jedoch zwei auf unterschiedlichen Höhen angeordnete Leuchten vorgesehen, sodass sowohl PKW -Fahrer als auch LKW-Fahrer das optische Warnsignal wahrnehmen können. Die auf Höhe eines PKW-Fensters angeordnete Leuchte befindet sich ungefähr im Bereich zwischen etwa 0,90 m und etwa 1,30 m Höhe gemessen vom Straßenbelag. Die auf Höhe eines LKW-Fensters angeordnete Leuchte befindet sich ungefähr im Bereich zwischen etwa 2, 10 m und etwa 2,70 m Höhe gemessen vom Straßenbelag. Nach einer weiteren bevorzugten Ausgestaltung ist die wenigstens eine Leuchte als Anzeige ausgebildet. Die Anzeige kann beispielsweise als Bildschirm ausgebildet sein. Insbesondere kann die Anzeige als Lauflicht ausgebildet sein.  However, two luminaires arranged at different heights are particularly preferably provided so that both passenger car drivers and lorry drivers can perceive the visual warning signal. The arranged at the height of a car window light is located approximately in the range between about 0.90 m and about 1.30 m height measured from the road surface. The luminaire arranged at the height of a truck window is located approximately in the area between about 2.10 m and about 2.70 m height measured from the road surface. According to a further preferred embodiment, the at least one lamp is designed as a display. The display can be designed for example as a screen. In particular, the display can be designed as a running light.
Insbesondere ist die wenigstens eine Leuchte konvex ausgebildet. Durch diese Ausgestaltung wird gleichfalls ein Geländer mit den oben genannten Vorteilen geschaffen. In particular, the at least one luminaire is convex. By this embodiment, a railing is also created with the above advantages.
Die Anzeigeeinrichtung weist bevorzugt eine den dem Kreuzungsbereich diagonal gegenüberliegenden Quadranten wenigstens teilweise ausleuchtende Beleuchtungseinrichtung auf. Mithilfe dieser Ausbildung wird eine sich an den Kreuzungsbereich annähernde Person bei Dunkelheit besser wahrgenommen. Die Anzeigeeinrichtung weist weiter bevorzugt auf der ihrer Außenseite gegenüberliegenden (Innen-) Seite, also dem Radweg zugewandt, ein Schild oder eine Anzeige auf, die die Person, die sich der Nebenstraße nähert, auf die Gefahrensituation hinweist. Des Weiteren ist eine die Anzeigeeinrichtung mit Energie versorgende Photovoltaikanlage vorgesehen, sodass eine autarke Steuerung der Einrichtung ermöglicht ist. The display device preferably has a lighting device that at least partially illuminates the quadrant that is diagonally opposite the crossing region. With the help of this training, a person approaching the crossing area is better perceived in the dark. The display device further preferably has a sign or a display on the (inner) side opposite its outer side, that is to say facing the cycle path, which points out the danger situation to the person approaching the side street. Furthermore, a photovoltaic system supplying the display device with energy is provided so that a self-sufficient control of the device is made possible.
Schließlich ist die Anzeigeeinrichtung so eingerichtet, dass die zu erfassende Person bzw. erfasste Person ein Zweiradfahrer, insbesondere ein Radfahrer, ist.

Der Ab strahl winkel der Leuchte ist dabei durch gedachte, rechtwinklig zur Hauptstraße HS und Nebenstraße NS verlaufende Achsen begrenzt. For further clarification, a further embodiment according to the present invention is shown in Fig. 4, in which the display device is extended counter to the direction of travel of the driver AI along the main road HS. The dashed area is the area in which the warning signal of the display device AE can be perceived by the driver AI. From the beam angle of the lamp is limited by imaginary, perpendicular to the main road HS and side road NS extending axes.
Schließlich zeigt Fig. 5 eine schematische Seitenansicht einer besonders bevorzugt ausgestalteten Anzeigeeinrichtung AE gemäß der vorliegenden Erfindung Die Anzeigeeinrichtung AE weist eine Säule S mit in zwei unterschiedlichen Höhen angebrachten Leuchten LI, L2 auf. Die niedrig angeordnete Leuchte LI ist zur Warnung von PKW-Fahrern eingerichtet, wohingegen die hoch angeordnete Leuchte L2 zur Warnung von LKW-Fahrern eingerichtet ist. Finally, FIG. 5 shows a schematic side view of a particularly preferred display device AE according to the present invention. The display device AE has a column S attached at two different heights LI, L2 lights up. The low-mounted lamp LI is set up to warn car drivers, while the high-level lamp L2 is set up to warn truck drivers.
Wie für die niedrig angeordnete Leuchte LI gezeigt, kann die wenigstens eine Leuchte LI . L2 als Lichtband ausgebildet sein, wobei mittels Piktogrammen auf eine sich nähernde Person, beispielsweise ein Radfahrer, aufmerksam gemacht werden kann. As shown for the low light LI, the at least one light LI. L2 can be formed as a light band, by means of pictograms on an approaching person, such as a cyclist, can be made attentive.
Die in Fig. 5 dargestellte Anzeigeeinrichtung AE weist darüber hinaus eine Photovoltaikanlage PV auf, die den Betrieb der Anzeigeeinrichtung als autarkes Inselsystem ermöglicht. Der Sensor zum Erfassen der sich der Nebenstraße NS parallel zur Hauptstraße HS annähernden Person ist nicht dargestellt.
