Verfahren zur Übermittlung von VerkehrsinformationenProcedure for the transmission of traffic information
Die Erfindung befaßt sich mit einem Verfahren zum Übermitteln von Verkehrsinformationen an den Fahrzeuglenker und/oder direkt an Steuerorgane des Fahrzeuges.The invention is concerned with a method of transmitting of traffic information to the vehicle driver and / or directly to control organs of the vehicle.
Zur Steuerung und Lenkung des Straßen- und Schienenverkehrs ist die Mitteilung von Informationen an den Fahrzeuglenker oder an sonstige Steuerorgane des Fahrzeugs selbst erforderlich. Derartige Informationen betreffen beispielsweiseInformation is communicated to the driver of the vehicle in order to control and direct road and rail traffic or to other control organs of the vehicle itself. Such information relates to, for example
° Geschwindigkeitsbegrenzungen, 0 Überholverbot,
° Abbiegeverbot,° speed limits, 0 no overtaking,
° no turning,
° Stau-, Nebel-, Glatteis-, Aquaplaning- und Seitenwindwarnung,° traffic jam, fog, black ice, aquaplaning and crosswind warning,
° Straßensperrungen,° road closures,
0 Fahrtrichtungsempfehlungen, Umleitungen, 0 travel direction recommendations, detours,
° Vorfahrtsregelungen,° right of way,
0 Durchfahrtshöhe und/oder -breite von Bauwerken, 0 clearance height and / or width of structures,
° Brückenbelastbarkeit,° bridge load capacity,
° Zufahrtsberechtigungen oder -beschränkungen,° access authorizations or restrictions,
0 Park- und Halteverbote, 0 parking and stopping bans,
° Ortsangaben (Gemeinde, Straßenabschnitt),° Location information (municipality, street section),
° Baustellen,° construction sites,
° Fußgängerüberwege.° pedestrian crossings.
Meist erfolgt die Übermittlung solcher Informationen durch Aufstellung von entsprechenden Schildern, Tafeln und Lichtzeichen (Ampeln, Signale) entlang der Fahrbahn (Straße, Schiene) oder durch Kennzeichnungen auf der Fahrbahn selbst (Zebrastreifen, Haltelinien etc.), die vom Fahrzeuglenker erkannt und beachtet werden müssen, um einen sicheren und reibungslosen Verkehr zu gewährleisten.Such information is usually transmitted by setting up appropriate signs, boards and light signals (Traffic lights, signals) along the roadway (road, rail) or through markings on the roadway itself (Zebra crossings, stop lines, etc.) that must be recognized and observed by the vehicle driver in order to ensure safe and to ensure smooth traffic.

Au.3er dieser optischen Informationsübertragung werden auch Funkwege (Verkehrsfunk, Zugfunk) und induktive Verfahren (z.B. induktive Zugbeeinflußung) eingesetzt. Diese Übertragungsarten erfordern jedoch gegenüber den optischen Zeichen wesentlich höhere Installations- und Wartungskosten. Bei der Funkübertragung wirkt sich zudem die bestehende Frequenzknappheit und die gegenseitige Beeinflussung der Funkstrecken hemmend auf den Einsatz aus.In addition to this optical information transmission, Radio paths (traffic radio, train radio) and inductive processes (e.g. inductive train control) are used. These types of transmission however, require significantly higher installation and maintenance costs than the optical signs. The existing frequency shortage and the mutual influence of the radio links also have an effect on radio transmission inhibiting use.
Nachteile optischer Signalisierung zum Fahrzeugführer entstehen durch erschwerte Erfassung beiDisadvantages of optical signaling to the driver arise by making it difficult to record
° hohen Fahrgeschwindigkeiten,° high driving speeds,
° Verschmutzung oder Beschädigung der Schilder,° soiling or damage to the signs,
0 Dunkelheit, 0 darkness,
° schlechter Witterung (Nebel, Regen, Schnee),° bad weather (fog, rain, snow),
° Konzentration des Fahrers auf den Verkehr,° concentration of the driver on the traffic,
0 Ablenkung, Ermüdung des Fahrers, 0 distraction, driver fatigue,
° zu großer Informationsmenge (Schilderwald),° too much information (forest of signs),
° Sehschwäche des Fahrers.° poor eyesight of the driver.
Selbst wenn der Fahrer die optisch übermittelte Information erkannt hat, besteht noch keine Gewähr dafür, daß er diese auch beachtet und sich entsprechend verhält. Automatische Erkennung, Auswertung und Steuerung bzw. Beeinflußung des Fahrzeuges, wie im Fall der induktiven Zugbeeinflußung, ist hierbei nicht möglich.Even if the driver has recognized the optically transmitted information, there is still no guarantee that he will have it also observes and behaves accordingly. Automatic detection, evaluation and control or influencing of the Vehicle, as in the case of inductive train control, is not possible here.
Durch das Nichterkennen und Nichtbeachten der optischen Signale durch den Fahrzeuglenker entstehen oft kritische Verkehrssituationen, die nicht selten zu Unfällen führen.Failure to recognize and ignore the optical signals by the vehicle driver often results in critical ones Traffic situations that often lead to accidents.
Geht man davon aus, daß die zu übermittelnden Informationen wesentlich für einen sicheren Verkehrsablauf sind, so sollte alles getan werden, um deren Erkennung und Beachtung sicherzustellen. If one assumes that the information to be transmitted is essential for a safe traffic flow, then should everything is done to ensure that they are recognized and observed.

Das Mittel der polizeilichen Kontrollen mit der Folge von Bußgeld- oder Strafverfahren um ein Fehl verhalten der Fahrer zu vermeiden, ist unzulänglich und mit hohen Kosten für die staatlichen Organe verbunden.The means of police controls with the consequence of Fine or criminal proceedings for misconduct by the Avoiding drivers is inadequate and involves high costs for government bodies.
Die Erfindung beschreibt ein technisches Verfahren, welches dazu dient, die Erkennung der genannten Informationen zu verbessern und die Möglichkeit einer automatischen Auswertung und Steuerung bzw. Beeinflussung des Fahrzeuges bietet.The invention describes a technical method which is used to identify the information mentioned and offers the possibility of an automatic evaluation and control or influencing of the vehicle.
Gelöst wird diese Aufgabe durch die Merkmale gemäß AnspruchThis object is achieved by the features according to the claim
Vorteilhafte Weiterbildungen der Erfindung werden in den Unteransprüchen gezeigt.Advantageous developments of the invention are in the Subclaims shown.
Die Grundlage des erfindungsgemäßen Verfahrens besteht darin, daß die an das Fahrzeug 6 und/oder dessen Fahrer zu Ti übermittelnde Information in einer z.B. quer, schräg, senkrecht oder längs zur Fahrbahn verlaufenden Strichkodierung enthalten ist.The basis of the method according to the invention is that the information to be transmitted to the vehicle 6 and / or its driver on Ti in a, for example, transverse, oblique, vertical or bar coding running along the road is included.
Diese Kodierung kann beispielsweise aus in ihrem Reflexions-Leitfähigkeitsverhalten von der übrigen Fahrbahnoberfläche abweichenden Querstrichen bestehen. Die Kodierung der Information kann dabei in an sich bekannter Weise durch die Breite eines oder mehrerer Striche und/oder deren Abstände erfolgen (sogen. Balken-Kodierung).This coding can be derived, for example, from its reflection-conductivity behavior there are horizontal lines that differ from the rest of the road surface. The coding of the information can take place in a manner known per se through the width of one or more lines and / or their spacing (so-called bar coding).
Durch Hinzufügen von Prüf informationen mittels zusätzlicher Bits oder Striche oder durch redundanten Aufbau der Kodierung kann die Erkennungssicherheit erhöht werden.By adding test information by means of additional bits or bars or by redundant structure of the coding the detection reliability can be increased.
Die erfindungsgemäße Kodierung kann darüber hinaus auch so gestaltet werden, daß daraus ein Rückschluß auf die Fahrtrichtung gezogen werden kann.The coding according to the invention can also be used in this way be designed so that a conclusion can be drawn about the direction of travel.

Ein über diese Kodierung hinwegfahrendes Fahrzeug tastet die Information ab, indem es von einer Quelle 1 Energie - vorzugsweise sichtbare Lichtenergie - auf die Fahrbahn abstrahlt. Diese wird abhängig von den Reflexionseigenschaften der Fahrbahn bzw. der aufgebrachten Streifen unterschiedlich stark reflektiert. Die reflektierte Energie wird von einem Empfänger 2 aufgenommen und einer Auswerteeinrichtung 3 zugeführt. Die Auswerteeinrichtung erkennt aus den vom Empfänger 2 kommenden elektrischen Werten die Breite und/oder die Abstände und/oder die Farbwerte der Streifen und bewertet deren Informationsinhalt, über eine Anzeige- und Steuereinheit 4 wird die so gewonnene Information dem Fahrzeuglenker zur Anzeige gebracht und/oder zur Betätigung von Fahrzeugfunktionen, wie Bremse, Kraftstoffzufuhr, benutzt.A vehicle driving over this coding scans the information by emitting energy - preferably visible light energy - from a source 1 onto the roadway. This varies in strength depending on the reflective properties of the roadway or the applied strips reflected. The reflected energy is picked up by a receiver 2 and fed to an evaluation device 3. The evaluation device recognizes the width and / or the distances and / or the color values of the stripes from the electrical values coming from the receiver 2 and evaluates them their information content, via a display and control unit 4, the information obtained in this way is displayed to the driver of the vehicle and / or to operate Vehicle functions, such as brakes, fuel supply, are used.
Die Auswertung der Information kann außerdem auch noch abhängig von der Fahrzeugart (PKW, LKW, Krad) unterschiedliche Aussagen ergeben. Derartige Unterschiede werden dem Auswerteprogramm durch entsprechende Voreinstellung der Auswerteeinrichtung 3 und/oder der Anzeige- und Steuereinrichtung 4 vorgegeben.The evaluation of the information can also vary depending on the type of vehicle (car, truck, motorcycle) Statements. Such differences are made clear to the evaluation program by appropriate presetting of the evaluation device 3 and / or the display and control device 4 specified.
Zur Verbesserung der Auswertesicherheit, d.h. der Genauigkeit der Form-, der Breiten- und/oder Abstandsermittlung der Strich-Kodierung, wird der Auswerteeinrichtung 3 von der Wegstrecken- oder Geschwindigkeitsmeßeinrichtung 5 des Fahrzeuges die zur Messung erforderliche Information zugeführt. Dadurch wird auch bei diskontinuierlicher Fahrzeuggeschwindigkeit, die den zeitweiligen Stillstand des Fahrzeuges einschließt, eine Kodeerkennung sichergestellt.To improve the evaluation reliability, i.e. the accuracy of the form, width and / or distance determination of the Bar coding, the evaluation device 3 is supplied with the information required for the measurement from the distance or speed measuring device 5 of the vehicle. This ensures code recognition even in the event of a discontinuous vehicle speed, which includes the temporary standstill of the vehicle.
Die durch den Kodeaufbau mögliche Erkennung der Fahrtrichtung kann vorteilhaft benutzt werden, um bei Überfahren desselben Kodes in der einen Richtung, beispielsweise an Grenzen geschlossener Ortschaften, eine Geschwindigkeitsbegrenzung zuThe recognition of the direction of travel made possible by the code structure can be used to advantage in order to limit the speed when driving over the same code in one direction, for example at the boundaries of built-up areas
- 9 - BK 84/115- 9 - BK 84/115
veranlassen, in der anderen Richtung dagegen diese Geschwindigkeitsbegrenzung wieder aufzuheben.cause this speed limit to be lifted in the other direction.
Neben der festen Aufbringung der Strich-Kodierung auf die Fahrbahn besteht die Möglichkeit der bedarfsweisen Aufbringung z.B. durch flexible Matten oder Platten, auf welchen die jeweilige Information in Form einer entsprechenden Strich-Kodierung enthalten ist. Dies kann bei der kurzfristigen Einrichtung von Baustellen, Umleitungen, Straßensperrungen sowie Stau-, Nebel- und Glatteiswarnungen von Vorteil sein.In addition to the fixed application of the bar coding on the roadway, there is the option of applying it as required, e.g. using flexible mats or plates on which the respective information is contained in the form of a corresponding bar coding. This can be the case with the short-term establishment of construction sites, diversions, road closures as well as traffic jam, fog and black ice warnings from Be an advantage.
Das beschriebene Verfahren der Informationsübermittlung kann auch dann angewendet werden, wenn die Strich-Kodierung seitlich neben der Fahrbahn senkrecht oder in besonderen Fällen über den Fahrzeugen waagrecht angebracht werden. Die im Fahrzeug befindliche abstrahlende Quelle und der Empfänger 2 müssen lediglich auf die Streifen-Kodierung ausgerichtet sein.The method of information transmission described can also be used if the bar coding is attached vertically next to the roadway or, in special cases, horizontally above the vehicles will. The emitting source located in the vehicle and the receiver 2 only need to be aligned with the stripe coding.
Den bisherigen Betrachtungen lagen Kodestreifen zugrunde, die aufgrund ihres gegenüber ihrer Umgebung unterschiedlichen Reflexions- oder Absorptionsverhaltens erkennbar sind.The previous considerations were based on code strips that are recognizable due to their different reflection or absorption behavior compared to their surroundings are.
Ebenso sind bei dem erfindungsgemäßen Verfahren aktiv energiesendende Strich-Kodierungen anwendbar.They are also active in the process according to the invention energy-sending bar codes can be used.
