Abstract

Durch das nicht Wahrnehmen oder verspätete Erkennen von Sondersignalen entstehen immer wieder Behinderungen von Einsatzfahrzeugen oder gar Unfälle. Die Erfindung hat das Ziel, andere Verkehrsteilnehmer frühzeitig und eindeutig von herannahenden Einsatzfahrzeugen mit eingeschaltetem Sondersignal zu warnen.
Die Erfindung liegt zugrunde, dass aus dem allgemeinen Geräuschpegel durch geeignete Signalverarbeitung die interessierenden Signale und Informationen, beispielweise Sondersignale, identifiziert und als Warnung akustisch oder visuell ausgegeben werden.By not perceiving or late recognition of special signals repeatedly arise obstructions of emergency vehicles or even accidents. The invention aims to warn other road users early and clearly of approaching emergency vehicles with activated special signal.
The invention is based on the fact that the signals of interest and information, for example special signals, are identified from the general noise level by suitable signal processing and emitted acoustically or visually as a warning.

Description

Jedes Einsatzfahrzeug ist mit einer Sondersignalanlage (Licht- und/oder Tonsignalanlage) ausgerüstet, um es für andere Verkehrsteilnehmer erkennbar zu machen. Ein Ziel des Kraftfahrzeugbaus jedoch ist die Verringerung der Lautstärke im Fahrzeuginnenraum. Lärmquellen befinden sich vor allem außerhalb des Fahrzeuges. Unglücklicherweise werden, diesem Ziel folgend, auch wichtige Sondersignale mit unterdrückt. Durch das nicht Wahrnehmen oder verspätete Erkennen von Sondersignalen entstehen immer wieder Behinderungen von Einsatzfahrzeugen oder gar Unfälle.Each emergency vehicle is equipped with a special signaling system (light and / or sound system) to make it recognizable to other road users. However, an object of the motor vehicle construction is the reduction of the volume in the vehicle interior. Noise sources are mainly outside the vehicle. Unfortunately, following this goal, important special signals are also suppressed. By not perceiving or late recognition of special signals repeatedly arise obstructions of emergency vehicles or even accidents.

Die Erfindung hat das Ziel, andere Verkehrsteilnehmer frühzeitig und eindeutig von herannahenden Einsatzfahrzeugen mit eingeschaltetem Sondersignal zu warnen.The invention aims to warn other road users early and clearly of approaching emergency vehicles with activated special signal.

Der Erfindung liegt zugrunde, dass aus dem allgemeinen Geräuschpegel durch geeignete Signalverarbeitung die interessierenden Signale und Informationen, beispielweise Sondersignale, identifiziert und als Warnung ausgegeben werden.The invention is based on the fact that from the general noise level by suitable signal processing, the signals of interest and information, for example, special signals, identified and issued as a warning.

Die Vorteile der Erfindung bestehen darin, dass Verkehrsteilnehmer frühzeitig und eindeutig über Fahrzeuge mit eingeschaltetem Sondersignal gewarnt werden. Dadurch können Behinderungen und Unfälle vermieden werden.The advantages of the invention are that road users are warned early and clearly about vehicles with the special signal on. As a result, disabilities and accidents can be avoided.

Die Erfindung bezieht sich auf das eindeutige Identifizieren von akustischen Sondersignalen. Aus diesen können zum Beispiel Informationen über die Art der Bewegung sowie die Geschwindigkeit der Signalquelle oder der Abstand bis zum Sondersignal ermittelt werden. Weiterhin kann die Erfindung auch auf optische Sondersignale ausgedehnt werden.The invention relates to the unique identification of special acoustic signals. From these, for example, information about the type of movement and the speed of the signal source or the distance to the special signal can be determined. Furthermore, the invention can also be extended to special optical signals.

Ein oder mehrere Mikrofone nehmen das Geräuschspektrum auf. Dieses Signal wird einem Mikrokontroller zugeführt, auf dem das Signal nach bekannten Sondersignalen analysiert wird. Das kann beispielweise über gespeicherte Kontrollmuster geschehen, Bewegungsarten, Bewegungsrichtungen und Abstand lassen sich beispielsweise über den Doppler-Effekt berechnen, erkannte Sondersignale und die berechneten Informationen sollen dem Verkehrsteilnehmer deutlich gemacht werden, was zum Beispiel akustisch oder visuell erfolgen kann (1). Die gleiche Verfahrensweise kann auch auf optische Sondersignale ausgedehnt werden, wobei die Rolle der Mikrofone durch Kameras übernommen wird.One or more microphones pick up the noise spectrum. This signal is fed to a microcontroller on which the signal is analyzed for known special signals. This can be done, for example, via stored control patterns, movement types, directions of movement and distance can be calculated for example via the Doppler effect, detected special signals and the calculated information should be made clear to the road user, which can be done acoustically or visually ( 1 ). The same procedure can also be extended to special optical signals, wherein the role of the microphones is taken over by cameras.
