Die Erfindung betrifft ein Warnsystem für Kurven.The The invention relates to a warning system for curves.
Es
sind schon Warnsysteme bekannt, die Straßenkrümmungen bzw. Kurven mittels
digitaler Karte (
Ein Warnsystem, das ohne Fahrereingriff die Geschwindigkeit reduziert, hat den Nachteil einer Fahrerbevormundung. Außerdem ist es beispielsweise bei einer Fehldetektion der Kurve relativ sicherheitskritisch. Ein Warnsystem, welches auch die Funktion eines Kurvenwarn- oder Kurveninformationssystems erfüllt, muss hingegen die Reaktionszeit des Fahrers berücksichtigen und wird entsprechend früher reagieren müssen als das bei einem eingreifenden System der Fall wäre. In der Regel wird ein Fahrer aber immer relativ kurzfristig vor einer Kurve die Geschwindigkeit reduzieren. Aus diesem Grunde kommt es zu unnötigen Warnungen, so dass der Fahrer das Warnsystem eher als störend empfinden könnte. Bei den aus dem Stand der Technik bekannten Warnsystemen besteht darüber hinaus das Problem, dass Krümmungen falsch geschätzt werden und dass wichtige Parameter, die für die Berechnung der möglichen Durchfahrtsgeschwindigkeit durch eine Kurve relevant sind, unbekannt sind, wie z.B. der Straßenzustand (Oberflächenbelag, Laub, Nässe, Eis), der Reifenzustand, die Fahrbahnneigungen usw.. Bei einer Warnung in Abhängigkeit von der aktuellen Geschwindigkeit zur möglichen Durchfahrtsgeschwindigkeit ist daher ein relativ hoher Testaufwand vor Systemfreigabe erforderlich. Die mögliche Durchfahrtsgeschwindigkeit (Grenzgeschwindigkeit) lässt sich dabei durch Gleichsetzen von Zentrifugalkraft und Haftreibungskraft berechnen. Die Geschwindigkeitsabhängigkeit erklärt sich dabei durch einen zunehmenden Aquaplaningeffekt auf nassen Fahrbahnbelägen.One Warning system that reduces the speed without driver intervention has the disadvantage of driver training. It is also, for example in a misdetection of the curve relatively safety-critical. One Warning system, which also functions as a curve warning or curve information system Fulfills, On the other hand, it has to take into account the reaction time of the driver and will react earlier accordingly have to than that would be the case with an intervening system. In the Usually, a driver is always in front of a turn relatively short term Reduce speed. For this reason, unnecessary warnings are generated so that the driver could feel the warning system rather than disturbing. at Moreover, the warning systems known from the prior art exist the problem that bends misjudged and that important parameters necessary for the calculation of the possible Throughput speeds through a curve are relevant, unknown are such as the road condition (Surface covering, Foliage, wetness, Ice), the tire condition, the road inclinations, etc. In case of a warning dependent on from the current speed to the possible passage speed Therefore, a relatively high test effort before system release is required. The possible passage speed (Limit speed) leaves doing so by equating centrifugal force and static friction force to calculate. The speed dependence is explained thereby by an increasing aquaplaning effect on wet road surfaces.
Des Weiteren spielt die Straßenquerneigung eine wichtige Rolle, z.B. können auf einem Hochgeschwindigkeitsoval durch die starke Querneigung trotz kleiner Radien hohe Geschwindigkeiten gefahren werden. Demnach müssen für eine exakte Bestimmung der Grenzgeschwindigkeit sehr viele Parameter bekannt sein, die unter Umständen durch Umweltsensoren detektiert werden müssen. Dabei lassen sich die Parameter in fahrzeugtypische (Reifenzustand, Fahrwerk, aktuelle Geschwindigkeit), fahrbahntypische (Belag, Neigung, Querneigung) und wettertypische (Regen, Temperatur, Eis, Laub) Parameter aufteilen.Of Furthermore, the street bank plays one important role, e.g. can despite the strong bank on a high speed oval small radii are driven at high speeds. Therefore, for an exact Determining the limit speed very many parameters known that may be must be detected by environmental sensors. This can be the Parameter in typical vehicle (tire condition, chassis, current Speed), roadway-typical (pavement, slope, bank) and typical weather (rain, temperature, ice, foliage) split parameters.
Darstellung der Erfindung, Aufgabe, Lösung, VorteilePresentation of the invention, Task, solution, advantages
Es ist deshalb Aufgabe der Erfindung, ein Warnsystem, welches die Funktion eines Kurvenwarnsystems erfüllt, zur Verfügung zu stellen, welches einen geringeren Testaufwand erfordert und unnötige Warnungen vermeidet.It is therefore an object of the invention, a warning system which the function meets a curve warning system, to disposal which requires less testing and unnecessary warnings avoids.
Gelöst wird diese Aufgabe durch ein Warnsystem mit den in Anspruch 1 angegebenen Merkmalen.Is solved This object is achieved by a warning system with the specified in claim 1 Features.
Die Grundidee der Erfindung ist die Verknüpfung eines Kurvenwarnsystems mit rechtlichen Geschwindigkeitsbegrenzungen, wobei das Kurvenwarnsystem eine Warneinrichtung enthält, die einen Fahrer des Fahrzeugs warnt, wenn der Fahrer trotz Einhaltung der vorgeschriebenen Geschwindigkeitsbegrenzung die Kurve nicht sicher durchfahren kann.The The basic idea of the invention is the linking of a curve warning system with legal speed limits, with the curve warning system contains a warning device, which alerts a driver of the vehicle when the driver, despite compliance the prescribed speed limit the curve is not safely pass through.
Ein Vorteil der Erfindung ist darin zu sehen, dass das Warnsystem mit wenigen Warnungen auskommt, weil in der Regel Geschwindigkeitslimits an kritischen Kurven aufgestellt sind. Lediglich vor Krümmungen, an denen keine Warnungen in Form von Hinweisschildern angebracht sind, würde gewarnt werden, d.h. das Warnsystem schließt gewissermaßen eine Sicherheitslücke. Auch wird der Fahrer nicht zum Austesten des Warnsystems ermutigt. Dazu basiert gemäß Anspruch 2 das Kurvenwarnsystem auf digitalen Kartendaten. Dabei ist in den Daten ein Ergebnis oder ein Zwischenergebnis, aus dem man das Endergebnis z.B. unter Berücksichtigung von weiteren, mit Sensoren bestimmten, Parametern oder fahrbahntypischen Parametern, etc. errechnen kann, abgelegt, ob die jeweilige Kurve mit der gesetzlich vorgeschriebenen Geschwindigkeit durchfahren werden kann oder nicht. Sollte dies nicht der Fall sein, handelt es sich bei der hier gewählten Terminologie um eine kritische Kurve. Das Warnsystem würde den Fahrer unabhängig von seiner aktuellen Geschwindigkeit vor einer solchen kritischen Kurve warnen. Der Fahrer würde also nur gewarnt werden, wenn er trotz Einhaltung der vorgeschriebenen Geschwindigkeitsbegrenzung die Kurve nicht sicher durchfahren könnte. Da ein Fahrer in der Regel etwas schneller fährt als vorgeschrieben, kann hierbei noch ein Sicherheitsaufschlag von z.B. 10% oder 10 Stundenkilometer berücksichtigt werden. Fahrer die sich nicht an diese Vorschriften halten, werden u.U. nicht gewarnt. Dies hat den Vorteil, dass das System nicht zur Geschwindigkeitsübertretung ermutigt, weil der Fahrer davon ausgeht, dass er notfalls in kritischen Situationen ohnehin gewarnt würde. Der Testaufwand wird für das Warnsystem minimiert, weil nicht für jede Kurve die genaue Grenzgeschwindigkeit ermittelt werden muss, sondern nur die Klassifikationsaufgabe „ist mit gesetzlichem Limit sicher durchfahrbar: JA/NEIN" zu lösen ist. Da digitale Karten die Basis für die Warnung sind, wird nur ein geringer Datensatz benötigt, weil im wesentlichen nur JA/NEIN-Informationen notwendig sind.One advantage of the invention is the fact that the warning system manages with few warnings, because usually speed limits are set at critical curves. Only in front of bends to which no warnings in the form of signs are attached, would be warned, ie the warning system closes a certain extent a security gap. Also, the driver is not encouraged to debug the warning system. For this purpose, the curve warning system is based on digital map data. Here, in the data, a result or an intermediate result, from which one can calculate the final result, taking into account, for example, other sensors, parameters or roadway typical parameters, etc., stored, whether the respective curve can be traversed at the statutory speed or not. If this is not the case, the terminology chosen here is a critical curve. The warning system would warn the driver of such a critical turn regardless of his current speed. The driver would therefore only be warned if, despite observance of the prescribed speed limit, the curve was not safe could drive through. Since a driver usually drives a little faster than prescribed, a safety charge of eg 10% or 10 km / h can be taken into account. Drivers who do not follow these rules may not be warned. This has the advantage that the system does not encourage speeding because the driver assumes that he would be warned in case of emergency anyway. The test effort is minimized for the warning system, because the exact limit speed does not have to be determined for each curve, but only the classification task "can be safely traversed with legal limit: YES / NO" is to be solved since digital maps are the basis for the warning. Only a small data set is needed because essentially only YES / NO information is necessary.
Neben dem (ggf. Zwischen-)Ergebnis und vielen weiteren Daten würden auch fahrbahntypische Parameter (Neigung, Querneigung, Belag, etc.) – sofern sie bekannt sind – mit in den digitalen Kartendaten abgelegt sein und/oder mit geeigneten Sensoren online erfasst werden.Next the (possibly intermediate) result and many other data would also typical roadway parameters (inclination, bank, pavement, etc.) - provided they are known - with be stored in the digital map data and / or with appropriate Sensors are recorded online.
Es ist von Vorteil, dass das Warnsystem ein Geschwindigkeitswarnsystem enthält, das mit dem Kurvenwarnsystem in Verbindung steht und einen Fahrer des Fahrzeugs vor Übertretung einer gesetzlich vorgeschriebenen Geschwindigkeitsbegrenzung warnt. Durch Kommunikation des Kurvenwarnsystem mit dem Geschwindigkeitswarnsystem ist ein erweitertes Warnsystem gewährleistet. Im Falle einer Geschwindigkeitsübertretung seitens des Fahrers des Fahrzeugs warnt das Geschwindigkeitswarnsystem, ansonsten das Kurvenwarnsystem. Auf diese Weise kann eine Kurvenwarnung in bestimmten Situationen vermieden werden.It It is advantageous that the warning system is a speed warning system contains that is related to the curve warning system and a driver the vehicle from violation a legally prescribed speed limit warns. By communicating the Curve Warning System with the Speed Alert System An extended warning system is guaranteed. In case of speeding on the part of the driver of the vehicle warns the speed warning system, otherwise the curve warning system. In this way, a turn warning in certain situations are avoided.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Warnungen über eine optische und/oder akustische und/oder haptische Ausgabe gegeben sind. Dadurch ist gewährleistet, dass die Warnungen dem Fahrer des Fahrzeugs über seine Sinnesorgane schnell zugeleitet werden.A advantageous embodiment of the invention provides that the warnings about a given optical and / or acoustic and / or haptic output are. This ensures that that the warnings are fast to the driver of the vehicle via his sense organs be forwarded.
Vorzugsweise enthält das Warnsystem ein Navigationssystem, das mit dem Kurven- und Geschwindigkeitswarnsystem in Verbindung steht und auf Grundlage digitaler Daten auf der digitalen Karte Fahrhinweise an den Fahrer gibt. Dies trägt der Tatsache Rechnung, dass der Fahrer des Fahrzeuges häufig zusätzlich noch Angaben über die Routenplanung benötigt.Preferably contains the warning system is a navigation system that uses the cornering and speed warning system communicating and based on digital data on the digital Map driving instructions to the driver there. This reflects the fact that the driver of the vehicle frequently additionally still information about the route planning needed.
Auch können bei dem Navigationssystem die Fahrhinweise über eine optische oder akustische Ausgabe gegeben sein.Also can in the navigation system, the driving information about a visual or audible output be given.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass das Kurvenwarnsystem und das Geschwindigkeitswarnsystem sowie das Navigationssystem mit Umweltsensoren in Verbindung stehen, die die Umweltbedingungen in der Kurvenkrümmung vermessen. Zu den digital abgelegten Daten kommen also noch zusätzliche Informationen von Umweltsensoren hinzu, wodurch sich die Einschätzung, welche Kurve kritisch ist, auf die jeweiligen Umweltbedingungen anpassen lässt. Bei den Umweltsensoren kann es sich beispielsweise um Regensensoren, Temperatursensoren, Neigungssensoren oder auch Reifendrucksensoren handeln. In den digitalen Kartendaten sollten zu den gesetzlich vorgeschriebenen Geschwindigkeiten auch Zusatzinformationen wie z.B. „bei Nässe" abgelegt sein, so dass eine Ergebniskorrelation mit den aktuellen gesetzlichen Geschwindigkeitsbegrenzungen auch bei unterschiedlichen Umweltbedingungen optimal erfolgen kann.A Another embodiment of the invention provides that the curve warning system and the speed warning system as well as the navigation system with Environmental sensors related to the environmental conditions in measure the curvature of the curve. To the digitally stored data so additional Information from environmental sensors adds to the assessment of which Curve is critical, adapt to the particular environmental conditions leaves. The environmental sensors may be, for example, rain sensors, temperature sensors, Tilt sensors or tire pressure sensors act. In the digital Map data should be at the legally prescribed speeds also additional information such. Be stored "wet", so that a result correlation with the current legal speed limits too can be done optimally under different environmental conditions.
Schließlich sieht die Erfindung ein Verfahren zur Warnung vor Krümmungen eines Verkehrsweges vor, bei dem ein Kurvenwarnsystem einen Fahrer des Fahrzeugs warnt, wenn der Fahrer trotz Einhaltung einer vorgeschriebenen Geschwindigkeitsbegrenzung eine Kurve nicht sicher durchfahren kann.Finally sees the invention provides a method for warning against curvatures of a traffic route, in which a curve warning system warns a driver of the vehicle when the driver despite compliance with a prescribed speed limit can not drive through a curve safely.
