Abstract

The car has an acoustic alarm. The loudness is greater during the day than at night. The loudness is controlled by the output signal of a brightness sensor and on-board electric clock.

Description

Die Erfindung bezieht sich auf ein Kraftfahrzeug mit einem akustischen Signalgeber. Mit Hilfe eines derartigen Gebers wird der Verriegelungszustand bzw. der Status einer Diebstahlwarnanlage oder aber auch der Zustand einer Beleuchtungsanlage (eingeschalteter Scheinwerfer) hörbar gemacht.The invention relates to a motor vehicle with an acoustic signal transmitter. With the help of such an encoder, the locked state or status an anti-theft alarm system or the condition of a lighting system (switched on headlight) made audible.

Ein derartiger Signalgeber ist bei einem hohen Umgebungs-Geräuschpegel nicht besonders deutlich zu hören. Er kann dann seiner eigentlichen Zweckbestimmung nicht dienen. In der Nacht hingegen ist der Umgebungs-Geräuschpegel in der Regel sehr niedrig. Die mit dem Signalgeber erzeugten Warn- bzw. Hinweistöne sind dann weithin hörbar und werden insbesondere für Unbeteiligte als störend empfunden.Such a signal generator is not at a high ambient noise level to hear particularly clearly. He can then use his actual purpose don't serve. In contrast, the ambient noise level is usually at night very low. The warning or advisory tones generated with the signal generator are then widely audible and are perceived as a nuisance, especially for bystanders.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Kraftfahrzeug der eingangs genannten Art die Hörbarkeit der mit dem Signalgeber ausgegebenen Warn- und Hinweistöne zu verbessern und andererseits die Geräuschbelästigung zu verrin­ gern.The invention has for its object in a motor vehicle of the beginning mentioned type the audibility of the warning and To improve advisory tones and, on the other hand, to reduce noise pollution gladly.

Die Erfindung löst diese Aufgabe durch die Merkmale des Patentanspruchs 1.The invention solves this problem by the features of claim 1.

Die Erfindung zeichnet sich durch einen äußerst geringen Aufwand aus, mit dem sowohl die Hörbarkeit vergrößert als auch die Geräuschbelästigung deutlich verrin­ gert wird.The invention is characterized by an extremely low outlay with which both increases audibility and significantly reduces noise pollution is gert.

Möglichkeiten, die Erfindung zu realisieren, bestehen beispielsweise darin, die Laut­ stärke in Abhängigkeit von einem Helligkeitssensor zu steuern. Dieser ermöglicht aufgrund der Umgebungsheiligkeit eine eindeutige Aussage über Tag- oder Nacht­ betrieb. Die Einbeziehung der Umfeldhelligkeit kann über den Solarsensor erfolgen. Dieser wird zunehmend für die Regelung der Klimatisierung in Kraftfahrzeugen verwendet. Dieser Sensor hat eine spektrale Empfindlichkeit im IR-Bereich. Hierdurch können Fehlmessungen (z. B. Straßenbeleuchtung) reduziert werden.Possibilities for realizing the invention are, for example, the sound to control strength depending on a brightness sensor. This enables due to the surrounding holiness, a clear statement about day or night business. The ambient brightness can be included via the solar sensor. This is increasingly used for the regulation of air conditioning in motor vehicles  used. This sensor has a spectral sensitivity in the IR range. In this way, incorrect measurements (e.g. street lighting) can be reduced.

Alternativ ist es auch möglich, die Tageszeit mit einer Bordnetzuhr zu bestimmen und entsprechend die Lautstärke einzustellen.Alternatively, it is also possible to determine the time of day using an on-board power supply clock and adjust the volume accordingly.

Die Lautstärke kann stufenweise - im einfachsten Fall eine tagsüber wirksame hohe Lautstärke und in der Nacht geringe Lautstärke - oder mit mehreren Stufen einge­ stellt werden. Es ist aber auch ein kontinuierlicher Übergang zwischen unterschiedli­ chen Lautstärken möglich.The volume can be gradually - in the simplest case, a high effective during the day Volume and low volume at night - or switched on with several levels be put. But it is also a continuous transition between different ones Chen volumes possible.
