Abstract

A road vehicle is fitted at the rear with a distance sensor (1) that is connected by cable (4) to an on board microcomputer (2). This connects with a display (3) that is visible to the following vehicle and issues warnings, such as to maintain a safe distance.

Description

Vorrichtung zur Messung der Distanz zum direkt folgenden Fahrzeug außerhalb geschlossener Ortschaften und optische Warnung des Fahrers des nachfolgenden Fahrzeuges bei Unterschreitung des gesetzlich geregelten Mindestabstandes.Distance measuring device to the immediately following vehicle outside of built-up areas and visual warning of the driver of the following vehicle Falling below the legally regulated minimum distance.

Die Erfindung betrifft eine Vorrichtung aus den Komponenten Radar / Infrarot / Ultraschall, Mikrocomputer bzw. elektronischer Schalt- und Regeleinheit und optischer Anzeigentafel zur Information des nachfolgenden Fahrzeuges.The invention relates to a device from the components radar / infrared / ultrasound, microcomputer or electronic switching and control unit and optical display board for information of the following vehicle.

Ein zu geringer Abstand zum vorausfahrenden Fahrzeug ist die dritthäufigste Unfallursache in Deutschland. Dabei birgt dichtes Auffahren nicht nur große Gefahren in sich, sondern auch saftige Strafen.An insufficient distance from the vehicle in front Vehicle is the third most common Cause of the accident in Germany. There is no tight opening only big Dangers in themselves, but also hefty punishments.

Laut des Statistischen Bundesamtes wird sie nur von "zu hoher Geschwindigkeit" und der "Nichtbeachtung der Vorfahrt" übertroffen.According to the Federal Statistical Office it is only from "to high speed "and of "disregard the right of way ".

Generell gilt die Faustformel für den Mindestabstand: Halber Tachowert in Metern. Wer Tempo 120 fährt, muss zum vorausfahrenden Fahrzeug also 60 Meter Distanz halten. Bei schlechter Sicht oder glatter Fahrbahn gilt es, den Raum zwischen den Autos entsprechend zu vergrößern. Ein Puffer nach der Regel "Tachowert gleich Abstand in Metern" sorgt für ausreichende Sicherheit bei schlechten Witterungsverhältnissen.In general, the rule of thumb applies for the minimum distance: Half tachometer value in meters. If you drive at 120 km / h, you have to drive ahead So keep the vehicle 60 meters away. In poor visibility or smoother It is important to enlarge the space between the cars accordingly. On Buffer according to the rule "speedometer value equal distance in meters " for sufficient Safety in bad weather conditions.

Bisher galten als eine Orientierungshilfe, um die Distanz ermessen zu können, die Leitpfosten seitlich der Straße. Sie stehen auf Autobahnen in einem 50-Meter-Intervall voneinander entfernt. Auf Landstraßen sind sie alle 25 Meter postiert.So far, it was considered a guide, to measure the distance the delineators on the side of the road. They are on highways in a 50 meter interval separated from each other. On country roads they are every 25 meters posted.

Durch einen ausreichenden Abstand zum vorausfahrenden Fahrzeug können Auffahrunfälle vermieden werden. Er schafft im wahrsten Sinne des Wortes Platz für eine rechtzeitige Reaktion auf unvermittelte Bremsmanöver des Vordermannes. Das gilt im Stadtverkehr sowie auch auf der Autobahn. Wer sich selbst durch zu dichtes Auffahren dieser Sicherheit beraubt, riskiert darüber hinaus ein Bußgeld und Punkte in Flensburg.By a sufficient distance to the vehicle in front Collisions avoided become. It literally creates space for timely Reaction to sudden braking maneuvers by the person in front. That applies in City traffic as well as on the highway. Anyone through themselves Deprived of this security too close, also risks a fine and points in Flensburg.

Bisher bieten einige Automobilhersteller Radarsysteme an, die den Fahrer unterstützen, den Sicherheitsabstand zu vorausfahrenden Fahrzeugen einzuhalten.So far, some car manufacturers offer Radar systems that support the driver, the safety distance to keep to vehicles in front.

Die Erfindung soll hingegen dazu dienen dem direkt nachfolgenden Fahrzeug Informationen über den Abstand zu geben und den Fahrer optisch warnen, wenn dieser abhängig von der jeweiligen Geschwindigkeit zu gering ist.The invention is intended to do so serve the directly following vehicle information about the Give distance and give the driver a visual warning if this depends on the respective speed is too low.

Erfindungsgemäß wird diese Aufgabe mit den Merkmalen des Schutzanspruches gelöst.According to the invention this task with the Features of the protection claim solved.
