Abstract

The invention relates to a warning light for motor vehicles which is arranged as a reflector (1) which shines backwards with the inscription "Keep your distance!" on the rear of the vehicle and lights up or flashes whenever the safety distance required for satisfactory braking of a more quickly travelling, following vehicle (4) is undershot. A computer (6) determines a value from the values of a speed measurement device (7) and a distance measurement device (9) in combination with the time and permanently programmed characteristic variables (reaction time, braking deceleration, friction, road/wheel) and transmits it to the control device (5) which controls the switching on of the reflector (1) after a desired value/actual value comparison. <IMAGE>

Description

Beschreibung description

Abstandswarnleuchte für Kraftfahrzeuge Die Erfindung betrifft eine speziell ausgestaltete Lichtzeichenanlage für Kraftfahrzeuge, nämlich eine Abstandswarnleuchte. Lichzeichenanlagen dienen ganz allgemein der Sicherheit im Straßenverkehr. Sie sind für einige Funktionen gesetzlich vorgeschrieben. So zeigen sie den anderen Verkehrsteilnehmern u. a. den Fahrzustand (z. B. das Bremsen durch Aufleuchten der Bremslichter) oder die beabsichtigte Fahrtrichtungsänderung (Blinker links oder rechts) des Fahrzeuges an. Distance warning light for motor vehicles The invention relates to a specially designed light signal system for motor vehicles, namely a distance warning light. Light signal systems are generally used for road safety. they are required by law for some functions. So show them to other road users i.a. the driving status (e.g. braking by lighting up the brake lights) or the intended change in the direction of travel (indicator left or right) of the vehicle at.

Den Brerlllichtern kommt dabei zur Kennzeichnung von C;efahrenssituationen -insbesoiidere zur Veroleidung von Auffahrunfällen - erheblich Bedeutung zu.The roaring lights are used to identify dangerous situations -insbesoiidere to avoid rear-end collisions - is of considerable importance.

Es ist bekannt, daß zur Erhöhung der Aufmerksamkeit bei Bremsvorgängen zusätzliche, erhöht placierte Bremslichter hinter den Heckscheiben montiert werden können.It is known that to increase the attention during braking additional, raised brake lights can be installed behind the rear windows can.

Diese vorhandenen Lichzeichenanlagen versetzen einen Fahrer eines nachfolgenden Fahrzeuges in die Lage, im Zusammenhang mit den sonstigen Verkehrsumweltbedirigungen (Kolonne steht oder ist in Fluß; Ampel springt auf grün oder auf rot, Abstand zum voranfahrenden Fahrzeug usw.) sein Fahrzeug angemessen zu steuern, also mehr oder weniger scharf zu bremsen oder itl Abhängigkeit von der eigenen Geschwindigkeit zu der des vorausfahrenden Fahrzeuges nur den Fuß vom Gaspedal zu nehmen. Dieses jeweils angemessene Reagieren setzt aber Erfahrung, gutes Sehvermögen (Entfernungseinschätzen, Geschwindigkeitseinschätzen) und gute Lichtverhältnisse voraus. Es kommt nicht von ungefähr, daß der Auffahrunfall eine der häufigsten Kollisionsarten zwischen zwei Fahrzeuge darstellt.These existing light sign systems put a driver in the position following vehicle in connection with the other traffic environmental conditions (Column stands or is in flow; traffic light jumps to green or red, distance to preceding vehicle, etc.) to control his vehicle appropriately, i.e. more or to brake less sharply or itl depending on your own speed to take your foot off the accelerator pedal in addition to that of the vehicle in front. This Reacting appropriately in each case requires experience, good eyesight (assessing distance, Speed assessment) and good lighting conditions ahead. It doesn't come from roughly that the rear-end collision is one of the most common types of collision between two Represents vehicles.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zu schaffen, die unabhängig von den Fahrleistungen der nachfolgenden Fahrer (Reaktion, Erfahrung, Sehvermögen) und den optischen Umweltbedingungen (Nacht, Nebel, Gegenlicht) Auffahrunfälle vermeiden hilft.The invention is based on the object of creating a device which are independent of the driving performance of the following drivers (reaction, experience, Eyesight) and the optical environmental conditions (night, fog, back light) rear-end collisions helps avoid.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an den Heckpartien der Fahrzeuge ein Rückstrahler mit der Aufschrift 'ABSTAND" montiert ist, der immer dann aufleuchtet, wenn für ein nachfolgendes Fahrzeug der Sicherheitsabstand für eine ordnungsgemäße Bremsung bzw. Verzögerung unterschritten wird.According to the invention, this object is achieved in that at the rear the vehicles have a reflector with the label 'SPIT' installed, which is always then lights up when the safety distance for a vehicle behind a proper braking or deceleration is not reached.

Der jeweilige Sicherheitsabstand hängt dabei von mehreren Faktoren ab: - Reaktion des Fahrers - Verzögerungsvermögen der Bremsen beim nachfolgenden Fahrzeug - Reibbeiwert Räder - Straße - Geschwindigkeitsdifferenz v2-v1 Während die ersten drei Faktoren für das voranfahrende Fahrzeug schwer oder nicht zu erfassen sind, so daß dafür Durchschnitts- bzw.The respective safety distance depends on several factors from: - reaction of the driver - deceleration ability of the brakes when following Vehicle - coefficient of friction wheels - road - speed difference v2-v1 during It is difficult or impossible to determine the first three factors for the vehicle in front are, so that for it average resp.

Erfahrungswerte angesetzt werden, läßt sich die Geschwindigkeitsdifferenz zwischen beiden Fahrzeugen sehr gut ermitteln.Empirical values are used, the speed difference determine very well between the two vehicles.

Es gibt heute schon Abstandsmei3einricixtungen lür l:ahrzeuge, die mit gesendeten und empfangenen, reflektierten Strahlen bzw. Wellen (Ultraschall, Radar) arbeiten. Werden die Werte in einen Rechner gegeben, so kann aus der Wegänderung über der Zeit die relative Geschwindigkeit ermittelt werden, mit der sich das nachfolgende Fahrzeug dem voranfahrenden nähert. Daraus läßt sich im Zusammenhang mit den o. g. Faktoren ein Sicherheitsabstand errechnen.There are already distance measurement devices for vehicles that do with transmitted and received, reflected rays or waves (ultrasound, Radar) work. If the values are entered into a computer, the path change can be made the relative speed with which the following Vehicle approaches the one in front. From this, in connection with the above G. Factors calculate a safety margin.

Gemäß dem Patentanspruch 1 wird immer dann der Rüciestrahler mit der Aufschrift "ABSTAND" aufleuchten, wenn von einen nachfolgenderl Fahrzeug dieser Mindestabstand für eine normale Bremsung unterschritten wird.According to claim 1, the back radiator is always with the The inscription "DISTANCE" lights up if this is from a following vehicle Minimum distance for normal braking is not reached.

Die auf diese Weise geschaffene Abstandswarnleuchte hat den großen Vorteil, unabhängig von vielen Randbedingungen (z. B. Lichtverhältnisse, Fahrvermögen usw.) den Fahrern nachfolgender Fahrzeuge einen Vorwarneffekt zu vermitteln und ihnen somit die Möglichkeit einer rechtzeitigen Bremsbereitschaft zu geben.The distance warning light created in this way has the big one Advantage regardless of many boundary conditions (e.g. lighting conditions, driving ability etc.) to give the drivers of following vehicles an advance warning effect and thus giving them the opportunity to be ready to brake in good time.

Diese erfindungsgemäße Abstandwarnleuchte stellt die z. Z. wirksamste Maßnahme zur Verhütung von Auffahrunfällen dar. Als sehr deutliches Beispiel sei hier das Heranfahrei mit hoher Geschwindigkeit an einen Stau auf der Autobahn genannt. Viele Fahrer reagieren hier mit der erforderlichen Bremseinleitung zu spät; sei es aus Gewöhnung an die über längere Zeit gefahrene und somit unterschätzte hohe Geschwindigkeit, sei es mangelnde Erfahrung/Routine oder Unachtsamkeit. In jedem Fall wird das rechtzeitige Aufleuchten des erfindungsgemäßen Rückstrahlers mit der Aufschrift "ABSTAND" eine hilfreiche Warnung sein und dazu beitragen, den Straßenverkehr sicherer zu machen.This distance warning light according to the invention represents the z. Currently most effective Measure to prevent rear-end collisions. Let me be a very clear example here the approaching at high speed to a traffic jam on the Highway called. Many drivers react too late by initiating the required braking; be it out of getting used to the long time driven and thus underestimated high speed, be it lack of experience / routine or carelessness. In in any case, the timely lighting up of the reflector according to the invention labeled "DISTANCE" can be a helpful warning and help reduce the Making road traffic safer.

In einer optisch sehr wirkungsvollen Ausführungsform mit hohem Erkennungwert ist der Rückstrahler als Blinklicht mit zwei Helligkeitsstufen ausgebildet. Die Aufschrift "ABSTAND" ist sinnvoll in schwarz auf rotem Grund angebracht, jedoch wäre auch gelb oder orange denkbar.In an optically very effective embodiment with a high recognition value the reflector is designed as a flashing light with two brightness levels. the The inscription "DISTANCE" makes sense in black on a red background, however yellow or orange would also be conceivable.

Die Placierung des Rückstrahlers am Heck erfolgt vorteilhaft in einfacher Ausführung mittig entwder hinter der Heckscheibe oder integriert in die vorhandene Rückleuchtenleiste. Eine Anordnung in zweifacher Ausführung rechts und links wie z. B. die Zusatzbremsleuchten wäre auch möglich.The placement of the reflector at the stern is advantageously carried out in a simple manner Execution in the middle either behind the rear window or integrated into the existing one Taillight strip. An arrangement in duplicate right and left like z. B. the additional brake lights would also be possible.

Statt der Aufschrift "ABSTAND" sind auch andere Begriffe denkbar, z. B.Instead of the inscription "DISTANCE", other terms are also conceivable, z. B.

"BREMSEN" oder "HALT" oder die international bekannte Formel "STOP'."BREMSEN" or "HALT" or the internationally known formula "STOP".

Einige Ausführungsformen und Erläuterungen der Erfindung sind in den Zeichnungen dargestellt.Some embodiments and illustrations of the invention are shown in FIGS Drawings shown.

Es zeigen: Fig. 1: Die Heckpartie eines Fahrzeuges mit der Abstandwarnleuchte hinter der Heckscheibe.They show: Fig. 1: The rear section of a vehicle with the distance warning light behind the rear window.

Fig. 2: Die Heckpartie eines Fahrzeuges mit der Abstandwarnleuchte in die Rückleuchtenleiste integriert.Fig. 2: The rear of a vehicle with the distance warning light integrated in the tail light strip.

Fig. 4: Ein Diagramm mit der Grenzkurve für den Mindest -Sicherheitsabstnd.Fig. 4: A diagram with the limit curve for the minimum safety distance.

Eine sehr vorteilhafte Anordnung der Warnleuchte 1 ist in Fig, 1 dargestellt.A very advantageous arrangement of the warning light 1 is shown in FIG.

Sie befindet sich relativ zentrisch im Fahrzeugquerschnitt und kann auch noch von dem zweiten und dritten nachfolgenden Fahrzeug wahrgenommen werden. It is located relatively centrally in the vehicle cross-section and can can also be perceived by the second and third following vehicles.

Die in Fig. 2 dargestellte Anordnung hat den Vorteil der Integration in die vorhandene Rückleuchtenleiste 2, aus der auch alle anderen Informationen für die nachfolgenden Fahrer kommen. The arrangement shown in Fig. 2 has the advantage of integration in the existing rear light strip 2, from which all other information come for the following drivers.

Fig. 3 zeigt ein Funktionsschema. Die rückwärtige Entfernungsmeßeinrichtung 9 sendet Strahlen (Wellen) 10 aus, die von dem nachfolgenden Fahrzeug 4 reflektiert werden und von der Entfernungsmeßeinriclltung 9 wieder -empfangen werden. Ein Rechner ermittelt aus der Laufzeit der Strahlen (Wellen) die Entfernung, also den Abstand zum Hindernis bzw. zum nachfolgenden Fahrzeug, Ist die Geschwindigkeit v2 des Fahrzeuges 4 größer als die Geschwindigkeit vl des Fahrzeuges 3, so verringert sich der Abstand Sv über der Zeit. Der Rechner 6 ermittelt aus den gefahrenen Geschwindigkeiten in Abhängigkeit von weiteren vorprogrammierten Kenngrößen (Bremsverzögerung, Reaktionszeit, Reibung Straße/Rad) den Mindest-Sicherheitsabstand S.3 shows a functional diagram. The rear distance measuring device 9 emits rays (waves) 10, which are reflected by the following vehicle 4 and are received again by the distance measuring device 9. A calculator determines the distance, i.e. the distance, from the transit time of the rays (waves) to the obstacle or to the following vehicle, is the speed v2 of the vehicle 4 is greater than the speed vl of the vehicle 3, the distance is reduced Sv over time. The computer 6 determines from the speeds driven in Dependence on other preprogrammed parameters (braking delay, reaction time, Friction road / wheel) the minimum safety distance S.

Wird er unterschritten, was in Fig, 4 durch den schraffierten Bereich 12 dargestellt ist, so veranlaßt das Steuergerät 5 den Kückstrahler 1 zum Aufleuchten. Der Fahrer des nachfolgenden Fahrzeuges 4 erhält rechtzeitig die Information zum Bremsen. If it falls below it, which is shown in FIG. 4 by the hatched area 12 is shown, the control unit 5 causes the reflector 1 to light up. The driver of the following vehicle 4 receives the information in good time Brakes.
