Definitions
- the invention relates to a traffic information system for motor vehicles.
- DE-A-29 40 205 discloses a device for warning of the risk of ice icy.
- a film which contains liquid crystals or temperature-indicating color pigments which change color at certain temperatures, optionally together with reflecting particles. The film becomes visible above a certain temperature and indicates the risk of slippage.
- the perceptibility of the device is low, since any kind of supply with external energy and / or activation to generate different traffic information is not provided.
- a system in which a conventional emergency column also serves as a transmitter for optical information signals.
- Such emergency call pillars are usually only arranged on motorways and are at least 1 km apart.
- it is necessary to arrange corresponding transmitters at a relatively short distance in order to achieve a higher information density. Because of their large distances, the known emergency call pillars are not suitable as carriers for corresponding transmitters.
- the invention has for its object to provide a traffic information system for motor vehicles, in which a sequence of traffic information signals can be generated with little design effort.
- such a road boundary post does not differ from one in which such a transmitter is missing. If one considers a section of the route, such a transmitter can be arranged in each road boundary post and thus, due to the generally short distance of 50 m, a dense network of such transmitters and thus an effective road-parallel traffic information system can be installed. The density can also be varied by only accommodating such a transmitter in every second road boundary post.
- the transmitter appears only insignificantly.
- This achieves another object of the invention. This consists in not allowing the traffic information system to appear or not appearing clearly in the inactive state. This is intended to prevent the driver from being weighed into false safety if the system cannot (yet) be activated or is activated, although this would be necessary due to an actually existing danger.
- the system should therefore only take on a supporting function, but on the other hand should not relieve the driver of the responsibility for careful driving. In this case, the cases are of importance in which the system is installed but is not yet in operation, or in which an installed system which is functional in itself is activated late.
- the transmitter does not appear visually or only insignificantly, if it is deactivated, it is difficult for the driver to distinguish sections of the route with and without such a traffic information system. He will never rely on being automatically alerted to an impending danger by such a system. As a consequence, this means that the driver does not change his driving behavior to the disadvantage compared to the situation in which such a traffic information system is not installed.
- the characteristic feature of claim 1 already serves this aim of accommodating the transmitter for such a traffic information system as inconspicuously as possible.
- the transmitter can be arranged within the field in which the reflection body is located. This makes it even more difficult to distinguish whether a road boundary post is equipped with such a transmitter if it is deactivated. Regardless of this, the transmitter is visually striking if it is activated. The goal of not letting the vehicle user easily recognize whether he is traveling on a route section with or without such a traffic information system is thus achieved even better.
- Another improvement is to conceal the surface of the transmitter by having a surface texture that corresponds to that of the reflection body. A deactivated transmitter therefore no longer appears optically.
- the transmitter when the transmitter is arranged in the direction of view behind the reflection body, which is transparent to the radiation emitted by the transmitter, a particularly advantageous embodiment of the invention.
- the advantage of this is that the reflection body remains effective at night and the presence of a deactivated transmitter is therefore not recognizable to the vehicle user even at night.
- the reflection body has an unrestrictedly effective surface.
- the effect of the reflection body is canceled by the activated transmitter, which then outshines the reflection body and, in particular when it is not directly exposed to direct illumination of motor vehicle lights, develops its effect.
- a transmitter 2 for optical information signals is contained in a commercially available road boundary post 1.
- the transmitter 2 sits in the head segment of the road boundary post 1 and is formed in two parts from an indicator light 3 for red and an indicator light 4 for a yellow light signal.
- a reflection body 6 in a black-painted field 5 defined by oblique boundary lines, which reflects incident headlight light and thus marks the roadside in connection with the following corresponding road boundary posts, not shown, posted on the roadside, not shown.
- the surface of the transmitter 2 can be designed in color so that, when the transmitter is deactivated, it does not differ, or differs only insignificantly, from the surroundings in the (usually white) head segment of the road boundary post. It is therefore not readily apparent to the vehicle user that the road boundary post is equipped with such a transmitter, provided that the transmitter is deactivated. The driver is therefore not prompted by such a road delimitation post to change his driving behavior and, for example, to be led to the possibly incorrect assumption that the following section of the route is safe to drive on.
- the transmitter 2 in a road boundary post that has not been changed or has changed only insignificantly compared to a conventional post when the transmitter is not activated, it is possible to equip sections of the route with such transmitters in a more or less dense sequence.
- the optimal arrangement density also depends on the course of the road, with a sequence of transmitters at the usual distance of 50 to 100 meters if necessary provides effective warning or information for the vehicle user.
- the transmitter no longer appears in the deactivated state.
- the transmitter 2 is now arranged directly behind the reflection body 6, which is opaque to the optical signals of the transmitter.
- the transmitter can be located behind the reflection body 6 on the front side facing the vehicle user or else on the back side, in which a two-part reflection body 7 is present. In the exemplary embodiment, only the arrangement behind the reflection body 6 is shown.
- the transmitter consists of two lights 8, each consisting of a lamp 9, a reflector 10 and a transparent, red or yellow film 11 or 11 '.
- electrical lines 12 are provided, which lead to a control part 13 in the foot 14 of the route limitation post 1.
- Control part and foot part 13 and 14 are arranged below the road surface 15 (Fig. 6).
- the control part 13 is controlled and supplied with energy by supply lines 16 which connect the road boundary posts, which are equipped with such a transmitter 2, parallel to the roadside.
- the transmitter 2 no longer appears at all, provided that it is deactivated. It is therefore not at all apparent to the vehicle user whether the road boundary post is equipped with such a transmitter if the transmitter is inactive.
- the transmitter 2 Only when it is necessary to give the driver a warning or information signal is the transmitter 2 activated and emits red or yellow light through the reflection body 6. Due to the dense sequence of such transmitters, a particularly effective warning and information means can also be created, since the vehicle user can now be confronted with such warning or information signals in close succession. The prerequisite for this is that such transmitters are correspondingly frequently arranged in road boundary posts. This is theoretically possible for each post and leads to a sequence of transmitters that is the same as the sequence of the posts. Despite this high density of transmitters, due to the "invisible" accommodation of the transmitters, the vehicle user is not prompted to change his driving behavior in a dangerous manner due to the inactivity of the transmitters.

Description
Die Erfindung bezieht sich auf ein Verkehrsinformationssystem für Kraftfahrzeuge.The invention relates to a traffic information system for motor vehicles.
In diesem Zusammenhang sind singuläre Sendeeinrichtungen bekannt, die in einem Straßenbegrenzungspfosten untergebracht sind. So ist beispielsweise aus der DE-A-29 40 205 eine Vorrichtung zum Warnen vor Eisglättegefahr bekannt. Am oberen und unteren Ende des Reflektionskörpers befindet sich jeweils eine Folie, die sich bei bestimmten Temperaturen verfärbende flüssige Kristalle oder temperaturanzeigende Farbpigmente, gegebenenfalls zusammen mit reflektierenden Partikeln, enthält. Über einem bestimmten Temperaturwert wird die Folie sichtbar und weist auf die Glättegefahr hin. Die Wahrnehmbarkeit der Vorrichtung ist gering, da eine irgendwie geartete Versorgung mit Fremdenergie und/oder eine Ansteuerung zur Erzeugung unterschiedlicher Verkehrsinformationen dabei nicht vorgesehen ist.In this context, singular transmission devices are known, which are accommodated in a road boundary post. For example, DE-A-29 40 205 discloses a device for warning of the risk of ice icy. At the upper and lower ends of the reflecting body there is a film which contains liquid crystals or temperature-indicating color pigments which change color at certain temperatures, optionally together with reflecting particles. The film becomes visible above a certain temperature and indicates the risk of slippage. The perceptibility of the device is low, since any kind of supply with external energy and / or activation to generate different traffic information is not provided.
Außerdem ist aus, der DE-AS 27 15 081 ein System bekannt, bei dem eine übliche Notrufsäule gleichzeitig als Sender für optische Informationssignale dient. Derartige Notrufsäulen sind in der Regel lediglich auf Autobahnen angeordnet und besitzen einen Abstand von mindestens jeweils 1 km. Bei zukünftigen infrastrukturellen Maßnahmen zum Aufbau eines flächendeckenden Verkehrsinformationssystems ist es jedoch erforderlich, entsprechende Sender in relativ geringem Abstand anzuordnen, um damit eine höhere Informationsdichte zu erreichen. Die bekannten Notrufsäulen eignen sich aufgrund ihrer großen Abstände nicht als Träger für entsprechende Sender.In addition, from DE-AS 27 15 081 a system is known in which a conventional emergency column also serves as a transmitter for optical information signals. Such emergency call pillars are usually only arranged on motorways and are at least 1 km apart. In future infrastructural measures to set up a comprehensive traffic information system, however, it is necessary to arrange corresponding transmitters at a relatively short distance in order to achieve a higher information density. Because of their large distances, the known emergency call pillars are not suitable as carriers for corresponding transmitters.
Ferner ist aus der DE-A-27 18 352 bekannt, einzelne Straßenbegrenzungspfosten mit einer Lichtleiteinrichtung zu versehen, um auf der Vorderseite auftreffendes Licht eines entgegenkommenden Fahrzeugs oder dergleichen aufzunehmen und an der Rückseite des Straßenbegrenzungspfostens austreten zu lassen. Das Ziel dieser Vorrichtung ist lediglich, die Wahrnehmbarkeit des einzelnen Straßenbegrenzungspfosten zu verbessern.Furthermore, it is known from DE-A-27 18 352 to provide individual road boundary posts with a light guide device in order to receive light from an oncoming vehicle or the like that hits the front and let out at the back of the road boundary post. The aim of this device is only to improve the visibility of the individual road boundary post.
Der Erfindung liegt die Aufgabe zugrunde, ein Verkehrsinformationssystem für Kraftfahrzeuge zu schaffen, bei dem mit konstruktiv geringem Aufwand eine Folge von Verkehrsinformationssignalen erzeugt werden kann.The invention has for its object to provide a traffic information system for motor vehicles, in which a sequence of traffic information signals can be generated with little design effort.
Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1.The invention solves this problem by the characterizing features of patent claim 1.
Durch die Unterbringung des Senders in einem Straßenbegrenzungspfosten unterscheidet sich somit ein derartiger Straßenbegrenzungspfosten nicht von einem, bei dem ein derartiger Sender fehlt. Betrachtet man einen Streckenabschnitt, so läßt sich in jedem Straßenbegrenzungspfosten ein derartiger Sender anordnen und damit aufgrund des in der Regel gegebenen geringen Abstands von 50 m ein dichtes Netz von derartigen Sendern und damit ein wirksames straßenparalleles Verkehrsinformationssystem installieren. Die Dichte läßt sich darüberhinaus variieren, indem lediglich in jedem zweiten Straßenbegrenzungspfosten ein derartiger Sender untergebracht ist.By placing the transmitter in a road boundary post, such a road boundary post does not differ from one in which such a transmitter is missing. If one considers a section of the route, such a transmitter can be arranged in each road boundary post and thus, due to the generally short distance of 50 m, a dense network of such transmitters and thus an effective road-parallel traffic information system can be installed. The density can also be varied by only accommodating such a transmitter in every second road boundary post.
Durch die Unterbringung in einem Straßenbegrenzungspfosten tritt der Sender zugleich nur unwesentlich in Erscheinung. Damit wird eine weitere Aufgabe der Erfindung gelöst. Diese besteht darin, das Verkehrsinformationssystem im inaktiven Zustand nicht oder nicht deutlich in Erscheinung treten zu lassen. Dadurch soll erreicht werden, den Fahrer nicht in falsche Sicherheit zu wiegen, wenn das System (noch) nicht aktivierbar bzw. aktiviert ist, obwohl dies aufgrund einer tatsächlich bestehenden Gefahr erforderlich wäre. Das System soll somit lediglich unterstützende Funktion übernehmen, den Fahrer andererseits aber nicht von der Verantwortung für vorsichtiges Fahren zu befreien. Es sind hierbei die Fälle von Bedeutung, bei denen das System zwar installiert, jedoch noch nicht in Betrieb ist oder bei denen ein installiertes, an sich funktionsfähiges System verspätet aktiviert wird.Due to the placement in a road boundary post, the transmitter appears only insignificantly. This achieves another object of the invention. This consists in not allowing the traffic information system to appear or not appearing clearly in the inactive state. This is intended to prevent the driver from being weighed into false safety if the system cannot (yet) be activated or is activated, although this would be necessary due to an actually existing danger. The system should therefore only take on a supporting function, but on the other hand should not relieve the driver of the responsibility for careful driving. In this case, the cases are of importance in which the system is installed but is not yet in operation, or in which an installed system which is functional in itself is activated late.
Da der Sender optisch nicht oder nur unwesentlich in Erscheinung tritt, sofern er deaktiviert ist, lassen sich für den Fahrer Streckenabschnitte mit und ohne einem derartigen Verkehrsinformationssystem schwer von einander unterscheiden. Er wird sich somit nie darauf verlassen, durch ein derartiges System automatisch und rechtzeitig auf eine bevorstehende Gefahr aufmerksam gemacht zu werden. In der Konsequenz bedeutet dies, daß der Fahrer gegenüber der Situation, bei ein derartiges Verkehrsinformatiossystem nicht installiert ist, sein Fahrverhalten nicht zum Nachteil ändert.Since the transmitter does not appear visually or only insignificantly, if it is deactivated, it is difficult for the driver to distinguish sections of the route with and without such a traffic information system. He will never rely on being automatically alerted to an impending danger by such a system. As a consequence, this means that the driver does not change his driving behavior to the disadvantage compared to the situation in which such a traffic information system is not installed.
Diesem Ziel, den Sender für ein derartiges Verkehrsinformatiossystem möglichst unauffällig unterzubringen, dient bereits das kennzeichnende Merkmal des Patentanspruchs 1. In Verbesserung hierzu kann der Sender innerhalb des Feldes angeordnet sein, in dem der Reflexionskörper sitzt. Dadurch wird es noch schwieriger, zu unterscheiden, ob ein Straßenbegrenzungspfosten mit einem derartigen Sender ausgerüstet ist, sofern dieser deaktiviert ist. Unabhängig davon tritt der Sender optisch auffallend in Erscheinung, sofern er aktiviert ist. Damit wird das Ziel, den Fahrzeugbenutzer nicht ohne weiteres erkennen zu lassen, ob er einen Streckenabschnitt mit oder ohne einem derartigen Verkehrsinformationssystem befährt, noch besser erreicht.The characteristic feature of claim 1 already serves this aim of accommodating the transmitter for such a traffic information system as inconspicuously as possible. In an improvement to this, the transmitter can be arranged within the field in which the reflection body is located. This makes it even more difficult to distinguish whether a road boundary post is equipped with such a transmitter if it is deactivated. Regardless of this, the transmitter is visually striking if it is activated. The goal of not letting the vehicle user easily recognize whether he is traveling on a route section with or without such a traffic information system is thus achieved even better.
Eine weitere Verbesserung besteht darin, die Oberfläche des Senders zu kaschieren, indem diese eine Oberflächenbeschaffenheit besitzt, die der des Reflexionskörpers entspricht. Ein deaktivierter Sender tritt somit optisch in keiner Weise mehr in Erscheinung.Another improvement is to conceal the surface of the transmitter by having a surface texture that corresponds to that of the reflection body. A deactivated transmitter therefore no longer appears optically.
Schließlich ergibt sich durch Anordnung des Senders in Blickrichtung gesehen hinter dem Reflexionskörper, der für die vom Sender ausgehende Strahlung durchlässig ist, eine besonders vorteilhafte Ausgestaltung der Erfindung. Der Vorteil hiervon ist, daß in der Nacht der Reflexionskörper unverändert wirksam ist und somit auch in der Nacht die Anwesenheit eines deaktivierten Senders für den Fahrzeugbenutzer nicht erkennbar ist. Der Reflexionskörper besitzt in diesem Fall eine uneingeschränkt wirksame Oberfläche. Gleichzeitig wird im Bedarfsfall die Wirkung des Reflexionskörpers durch den aktivierten Sender aufgehoben, der dann den Reflexionskörper überstrahlt und insbesondere dann, wenn er nicht unmittelbar einer direkten Bestrahlung von Kraftfahrzeug-Leuchten ausgesetzt ist, seine Wirkung entfaltet.Finally, when the transmitter is arranged in the direction of view behind the reflection body, which is transparent to the radiation emitted by the transmitter, a particularly advantageous embodiment of the invention. The advantage of this is that the reflection body remains effective at night and the presence of a deactivated transmitter is therefore not recognizable to the vehicle user even at night. In this case, the reflection body has an unrestrictedly effective surface. At the same time, if necessary, the effect of the reflection body is canceled by the activated transmitter, which then outshines the reflection body and, in particular when it is not directly exposed to direct illumination of motor vehicle lights, develops its effect.

- ein zweites Ausführungsbeispiel, wobei in Fig. 1 und 6 ein Straßenbegrenzungspfosten in der Vorderansicht, in Fig. 2 und 7 bzw. 3 und 8 eine Seitenansicht hierzu in geschlossener bzw. teilweise offener Form, in Fig. 4 und 9 ein Ausschnitt von Fig. 3 bzw. 8 in der Vorderansicht und in Fig. 5 und 10 eine Vorderansicht analog zu Fig. 1 bzw. 6 in vollständige, teilweise offener Darstellung gezeigt ist.

- a first embodiment of the invention and
- Fig. 6-10
- a second embodiment, wherein in Fig. 1 and 6 a road boundary post in the front view, in Fig. 2 and 7 or 3 and 8 a side view of this in a closed or partially open form, in Fig. 4 and 9 a detail of Fig. 3 and 8 in the front view and in FIGS. 5 and 10 a front view analogous to FIGS. 1 and 6 is shown in complete, partially open representation.
Im Ausführungsbeispiel von Fig. 1-5 ist in einem handelsüblichen Straßenbegrenzungspfosten 1 ein Sender 2 für optische Informationssignale enthalten. Der Sender 2 sitzt im Kopfsegment des Straßenbegrenzungspfosten 1 und ist zweigeteilt aus einer Anzeigeleuchte 3 für rotes und einer Anzeigeleuchte 4 für ein gelbes Lichtsignal ausgebildet.In the exemplary embodiment of FIGS. 1-5, a
Unterhalb des Senders 2 befindet sich in einem durch schräge Begrenzungslinien definierten, schwarz lackierten Feld 5 ein Reflexionskörper 6, der auftreffendes Scheinwerferlicht reflektiert und damit in Verbindung mit den folgenden, am Straßenrand postierten, nicht dargestellten entsprechenden Straßenbegrenzungspfosten den Straßenrand markiert.Below the
Die Oberfläche des Senders 2 kann farblich so gestaltet sein, daß sie sich bei deaktiviertem Sender nicht oder nur unwesentlich von der Umgebung im (in der Regel weißen) Kopfsegment des Straßenbegrenzungspfostens unterscheidet. Damit ist es für den Fahrzeugbenutzer nicht ohne weiteres erkennbar, daß der Straßenbegrenzungspfosten mit einem derartigen Sender ausgerüstet ist, sofern der Sender deaktiviert ist. Der Fahrer wird somit durch einen derartigen Straßenbegrenzungspfosten nicht veranlaßt, sein Fahrverhalten zu verändern und sich beispielsweise zu der möglicherweise falschen Annahme verleiten lassen, der nachfolgende Streckenabschnitt sei gefahrlos zu befahren.The surface of the
Andererseits besteht durch die Anordnung des Senders 2 in einem bei nicht aktiviertem Sender nicht oder nur unwesentlich gegenüber einem herkömmlichen Pfosten geänderten Straßenbegrenzungspfosten die Möglichkeit, Streckenabschnitte in mehr oder weniger dichter Folge mit derartigen Sendern auszurüsten. Die optimale Anordnungsdichte richtet sich auch nach dem Straßenverlauf, wobei eine Folge von Sendern im üblichen Abstand von 50 bis 100 Meter in Bedarfsfall eine wirksame Warnung bzw. Information für den Fahrzeugbenutzer liefert.On the other hand, by arranging the
Beim Ausführungsbeispiel nach den Fig. 6 bis 10 besteht insofern eine Verbesserung, als der Sender nunmehr im deaktivierten Zustand überhaupt nicht mehr in Erscheinung tritt. Der Sender 2 ist nunmehr unmittelbar hinter dem für die optischen Signale des Senders undurchlässigen Reflexionskörper 6 angeordnet. Der Sender kann dabei hinter dem Reflexionskörper 6 auf der dem Fahrzeugbenutzer zugewandten Vorderseite oder aber auch auf der Rückseite liegen, bei der ein zweigeteilter Reflexionskörper 7 vorhanden ist. Im Ausführungsbeispiel ist lediglich die Anordnung hinter dem Reflexionskörper 6 dargestellt.In the exemplary embodiment according to FIGS. 6 to 10, there is an improvement in that the transmitter no longer appears in the deactivated state. The
Der Sender besteht aus zwei Leuchten 8, die jeweils aus einer Lampe 9, einem Reflektor 10 sowie einer transparenten, roten bzw. gelben Folie 11 bzw. 11′ bestehen. Zur Stromversorgung der Lampen 9 sind elektrische Leitungen 12 vorgesehen, die zu einem Steuerteil 13 im Fuß 14 des Streckenbegrenzungspfosten 1 führen. Steuerteil und Fußteil 13 bzw. 14 sind unterhalb der Straßenoberfläche 15 (Fig. 6) angeordnet. Das Steuerteil 13 wird durch Versorgungsleitungen 16 gesteuert und mit Energie versorgt, die parallel zum Straßenrand die Straßenbegrenzungspfosten miteinander verbinden, die mit einem derartigen Sender 2 ausgerüstet sind.The transmitter consists of two
Der Sender 2 tritt beim Ausführungsbeispiel nach den Figuren 6 bis 10 nunmehr überhaupt nicht mehr in Erscheinung, sofern er deaktiviert ist. Es ist für den Fahrzeugbenutzer somit überhaupt nicht zu erkennen, ob der Straßenbegrenzungspfosten mit einem derartigen Sender ausgerüstet ist, sofern der Sender inaktiv ist.In the exemplary embodiment according to FIGS. 6 to 10, the
Erst wenn es erforderlich ist, dem Fahrer ein Warn- bzw. Informationssignal zu geben, wird der Sender 2 aktiviert und strahlt durch den Reflexionskörper 6 hindurch rotes bzw. gelbes Licht ab. Durch die dichte Folge von derartigen Sendern läßt sich darüberhinaus ein besonders wirksames Warn- und Informationsmittel schaffen, da der Fahrzeugbenutzer nunmehr in dichter Folge mit derartigen Warn- bzw. Informationssignalen konfrontiert werden kann. Voraussetzung hierfür ist, daß entsprechend häufig derartige Sender in Straßenbegrenzungspfosten angeordnet sind. Dies ist theoretisch für jeden Pfosten möglich und führt zu einer Folge von Sendern, die gleich der Folge der Pfosten ist. Trotz dieser hohen Dichte von Sendern wird der Fahrzeugbenutzer aufgrund der "unsichtbaren" Unterbringung der Sender nicht veranlaßt, aufgrund der Inaktivität der Sender sein Fahrverhalten in gefährlicher Weise zu verändern.Only when it is necessary to give the driver a warning or information signal is the
