Abstract

An electronic system for the early recognition, in the car, of road traffic warning signals is characterised in that the noise of road traffic is picked up already outside the car. The audio sensitivity (acoustic sensitivity) of the car driver for these signals is increased by acoustically receiving them electronically at an early stage. The outside signals are constantly compared in an additional device with the known warning signals of police, ambulance and fire brigade. When a warning signal is recognised, the volume of the car radio is turned down. It is also possible to amplify the microphone signal in the radio.

Description

Die Erfindung betrifft eine elektronische Signalfrüherkennung von Warnsignalen der Polizei, Krankenwagen und Feuerwehr.The invention relates to electronic early signal detection of warning signals from the police, ambulance and fire brigade.

In fast jedem Auto ist heutzutage ein Autoradio eingebaut.A car radio is installed in almost every car these days.

Ist ein Autoradio während der Fahrt eingeschaltet, werden die Geräusche des Straßenverkehrs in einem entsprechenden Maße überdeckt. Kritisch kann eine Überdeckung der Alarmsignale von Polizei, Krankenwagen und Feuerwehr sein, denn je später solche Alarmsignale erkannt werden, desto weniger umsichtig und gestreßt verhält sich der Autofahrer.If a car radio is switched on while driving, the noise of road traffic is reduced covered a corresponding dimension. Coverage of the alarm signals from Police, ambulance and fire department, because the later such alarm signals are recognized, the less prudent and stressed the driver behaves.

Durch elektronische Erkennung der Warnsignale wird eine Hörfrühwahrnehmung durchgeführt und somit die Hörempfindlichkeit des Autofahrers für diese Signale erhöht.An early hearing perception is carried out by electronic detection of the warning signals and thus increases the driver's hearing sensitivity to these signals.

Aus der Patentschrift DE 41 23 857 C2 ist eine Anordnung zum Erkennen von Notdienstfahrzeugen bekannt, die von einem zusätzlichen Sendesignal der Einsatzfahrzeuge, neben dem Blaulicht und Martinshorn, ausgeht.From the patent DE 41 23 857 C2 an arrangement for recognizing Emergency service vehicles known by an additional transmission signal of the emergency vehicles, next to the blue lights and siren.

Diese Erfindung kommt ohne zusätzliche Signale aus und die Notdienstfahrzeuge bleiben davon unberührt.This invention manages without additional signals and the emergency service vehicles remain unaffected.

Am Auto werden vorne und hinten Akustikwandler außen angebracht. Die Signale dieser Akustikwandler werden analog oder digital mit den bekannten Alarmsignalen der Polizei, Feuerwehr und Krankenwagen ständig verglichen.Acoustic transducers are attached to the front and rear of the car. The signals of this Acoustic transducers are analog or digital with the known alarm signals from the police, Fire department and ambulance constantly compared.

Wird ein Warnsignal erkannt, geht ein Steuerbefehl an die Arbeitsstufe des Radios, dessen Lautstärke sofort heruntergeregelt wird. Die Überdeckung durch das Radio ist aufgehoben und der Fahrer kann sich auf die Alarmsituation sofort konzentrieren.If a warning signal is detected, a control command goes to the radio's working level, its volume is immediately reduced. The coverage by the radio is removed and the Drivers can immediately focus on the alarm situation.

Bei der Erkennung eines Warnsignalsignals kann auch eine Zwangsübertragung im Radio stattfinden. Dazu wird das Mikrofonsignal über den NF-Weg in das Radio eingekoppelt, das eigentliche NF-Signal wird heruntergeregelt und das Mikrofonsignal verstärkt.When a warning signal is detected, forced transmission can also take place on the radio. For this purpose, the microphone signal is coupled into the radio via the NF path actual LF signal is turned down and the microphone signal is amplified.

Aus dem Gebrauchsmuster DE 91 15 490 U1 ist eine solche Warnvorrichtung bekannt. Der Nachteil dieser Lösung ist die Verwendung von Mikrofonen als Akustikwandler, die in der Praxis aufgrund des Schalldrucks und anderer zerstörischer Einflüsse nur eine sehr kurze Lebensdauer haben. Die Funktionssicherheit der gesamten Anlage dürfte somit insgesamt gering sein.Such a warning device is known from utility model DE 91 15 490 U1. Of the Disadvantage of this solution is the use of microphones as acoustic transducers, which in practice due to the sound pressure and other destructive influences only a very short lifespan to have. The overall functional reliability of the entire system should therefore be low.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Anordnung für eine elektronische Signalfrüherkennung zu schaffen, die sich durch extreme Zuverlässigkeit auszeichnet.The invention is therefore based on the object of an arrangement for to create an electronic signal early detection system that is characterized by characterized by extreme reliability.

Die Aufgabe wird durch die Merkmale im Patentanspruch gelöst.The object is achieved by the features in the claim solved.
