Abstract

In order to increase the safety of moving vehicles, a warning signal for the vehicles behind is triggered by the respective individual vehicle, by the control signal which is required for this being derived directly from the negative acceleration. The solution of this technical problem takes the form of electronically determining the deceleration value, comparing it with a presettable limit value and feeding it to a warning device when the limit value is exceeded. Preferably, the aforesaid warning device is applied in public road traffic. Additional possible uses for the device are the semi-automatic and/or automatic control of queues of traffic.

Description

Beschreibung:Description:

Die Erfindung bezieht sich auf das Messen einer Geschvrindigkeitsreduzierung eines bewegten Objektes, insbesonders Fahrzeuge des öffentlichen Straßenverkehrs und eine Gewinnung von 'farn- und Regel signalen.The invention relates to measuring a speed reduction of a moving object, especially vehicles used on public roads and an acquisition of fern and rule signals.

Die durch die Einrichtung gewonnen Warn- und Regelsignale dienen, auf Fahrzeuge des öffentlichen Verkehrs bezogen, dem nachfolgenden Verkehrsfluß zur Geschwindigkeitsanpassung an vorausfahrende Fahrzeuge.The warning and control signals obtained by the device are used, related to public transport vehicles, the subsequent flow of traffic to adapt the speed to vehicles in front.

Es ist bekannt, daß an Fahrzeugen, die am öffentlichen Straßenverkehr teilnehmen, der nachfolgende Verkehrsstrom durch eine optische arneinrichtung ( Bremsschlußleuchten ), deren Funktion beim Betätige der Bremseinrichtung ausgelöst wird, gewarnt wird. er Fahrer des nachfolgenden Fahrzeuges hat sein Fahrverhalten entsprechend einzurichten.It is known that on vehicles used on public roads participate, the subsequent traffic flow through an optical alarm device ( Brake tail lights) whose function is triggered when the braking device is actuated is warned. he driver of the following vehicle has his driving behavior set up accordingly.

er Nachteil dieser Betriebsart liegt in folgenden Punkten: - keine Signalgabe bei Geschwindigkeitsreduzierung infolge Gaswegnahme.he disadvantage of this mode of operation lies in the following points: - none Signal is given when speed is reduced as a result of the accelerator being released.

- keine Möglichkeit zur synchronisierten Bremsbetätigung hintereinetnder sich bewegender Fahrzeuge.- no possibility of synchronized brake actuation one after the other moving vehicles.

- individuelle Reaktion des Lenkers des nachfolgenden Fahrzeuges auf die optische warnung.- individual reaction of the driver of the following vehicle the visual warning.

- keine ;;;öglichkeit zur automatischen Regelung der Geschwindigkeit hintereinander fahrender Fahrzeuge.- none ;;; possibility of automatic speed control vehicles driving one behind the other.

Der Erfindung liegt die Aufgabe zu Grunde, eine arn-und Degeleinrichtung zu schaffen, die auf die tatsächliche Geschwindigkeitsreduzierung als Meßgröße zurückgreift und nicht auf die Betätigung einer Betriebseinheit.The invention is based on the object of an arn and control device to create, which falls back on the actual speed reduction as a measured variable and not to the actuation of an operating unit.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die dinrichtung in ihren kennzeichnenden Merkmalen dem Patentanspruch 1 entspricht.The object is achieved according to the invention in that the dinrichtung corresponds to claim 1 in its characterizing features.

Um eine solche Einrichtung in einfacher Weise zu realisieren muß sie - die Beschleunigungsgröße erfassen - die Signalgröße verstärken - die Signalgröße mit einem voreinstellbaren Grenzwert vergleichen - eine optische, optoakustische oder akustische t;iarneinrichtung durch geeignete Mittel ansteuern - in besonderen Fällen eine drahtlose Funktionsweise in mindestens zwei Fahrzeugen ermöglichen.In order to implement such a device in a simple manner, it must - record the acceleration size - amplify the signal size - the signal size compare with a preset limit value - an optical, optoacoustic one or control acoustic warning devices by suitable means - in particular Cases enable wireless functionality in at least two vehicles.

- je nach vorhandenen tlatz in diskreter Schaltungstechnik oder in integrierter Bauweise ausgestaltet sein Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß - eine fruhzeitigere Mctivierung der Warneinrichtung erfolgt und damit die Sicherheit (Einhaltung des Sicherheitsabstandes ) im öffentlichen Straßenverkehr erhöht wird.- depending on the available space in discrete circuit technology or in integrated design The advantages achieved with the invention are in particular that - an earlier activation the warning device and thus the safety (compliance with the safety distance ) is increased in public road traffic.

- eine automatische Einhaltung des Sicherheitsabstandes gewährleistet wird.- automatic compliance with the safety distance is guaranteed will.
