Description
Die Erfindung bezieht sich auf ein Audiosystem für Kraftfahrzeuge nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an audio system for motor vehicles according to the preamble of claim 1
Ein
derartiges Audiosystem ist beispielsweise aus der
Es ist Aufgabe der Erfindung, ein Audiosystem eingangs genannter Art hinsichtlich der Berücksichtigung weiterer Störgeräusche zu verbessern.It Object of the invention, an audio system of the type mentioned in terms of consideration to further noise improve.
Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind die Gegenstände der abhängigen Patentansprüche.These The object is achieved by the The subject of claim 1 solved. Advantageous developments are the objects the dependent Claims.
Das erfindungsgemäße Audiosystem für Kraftfahrzeuge weist eine Signalausgabeeinheit und eine Steuereinheit auf, die abhängig von verschiedenen Eingangssignalen verschiedene Audiosignale über die Signalausgabeeinheit ausgeben kann. Die Steuereinheit enthält ein Modul zur automatischen Lautstärkeanpassung der Audiosignale abhängig von einem ein Störgeräusch wiedergebenden Signal in Form eines Signals, das die Drehzahl eines Gebläses der Klimaanlage wiedergibt, und/oder in Form eines Signals, das den Öffnungsgrad eines Fensters und/oder eines Schiebedaches wiedergibt.The audio system according to the invention for motor vehicles has a signal output unit and a control unit which dependent different audio signals from the different input signals via the signal output unit can spend. The control unit contains a module for automatic volume adjustment the audio signals depends on causing a noise Signal in the form of a signal representing the speed of a fan of the Air conditioning reproduces, and / or in the form of a signal indicating the degree of opening a window and / or a sunroof.
Die Audiosignale können in zwei Gruppen eingeteilt werden. Vorzugsweise ist eine erste Gruppe von Audiosignalen durch frequenzmäßig eher breitbandige Signale und eine zweite Gruppe von Audiosignalen durch frequenzmäßig eher schmalbandige Signale gebildet. Die Gruppen können beispielsweise anhand von definierten Frequenzbändern festgelegt werden. Unterschiedlich Lautstärkevorgaberegeln zur Lautstärkeanpassung sind beispielsweise derart definiert, dass die Lautstärke der Audiosignale der zweiten Gruppe verglichen mit der Lautstärke der Audiosignale der ersten Gruppe mit zunehmendem Störgeräusch schneller angehoben wird.The Audio signals can be divided into two groups. Preferably, a first group of audio signals by frequency rather broadband signals and a second group of audio signals by frequency rather narrowband signals formed. For example, the groups can be based on of defined frequency bands be determined. Different volume setting rules for volume adjustment are defined, for example, such that the volume of the Audio signals of the second group compared to the volume of the audio signals the first group is raised faster with increasing noise.
Beispielsweise ist eine erste Gruppe von Audiosignalen durch Entertainment-Signale und eine zweite Gruppe von Audiosignalen durch Warnton-Signale und/oder Navigations-Ausgabesignale gebildet. Es könnten auch mehr als zwei Gruppen definiert werden.For example is a first group of audio signals through entertainment signals and a second Group of audio signals by warning sound signals and / or navigation output signals educated. It could also more than two groups can be defined.
Der
Erfindung liegen folgende Erkenntnisse zugrunde:
Bisher wird
eine Lautstärkeanpassung
nur in Abhängigkeit
von der Fahrzeuggeschwindigkeit vorgenommen, die insbesondere ein
von der Brennkraftmaschine erzeugtes Störgeräusch wiedergibt. Weiterhin sind
Systeme bekannt, die im Zusammenhang mit einer Lautstärkeanpassung
die Gesamtheit aller Störgeräusche im
Kraftfahrzeug mittels eines Mikrofons erfassen. Derartige Systeme
sind jedoch kostenintensiv und benötigen zu den ohnehin vorhandenen Steuergeräten hinzu
weitere Komponenten.The invention is based on the following findings:
So far, a volume adjustment is made only as a function of the vehicle speed, which reproduces in particular a noise generated by the internal combustion engine. Furthermore, systems are known which detect the totality of all noise in the motor vehicle by means of a microphone in connection with a volume adjustment. However, such systems are costly and require additional components to the already existing control devices.
Die Weiterbildung der Erfindung berücksichtigt noch einen anderen Aspekt bei Lautstärkeanpassungen in Kraftfahrzeugen: Beim Stand der Technik wird die Lautstärke aller Audiosignale in einem Kraftfahrzeug mit steigendem Störgeräusch durch ein- und dieselbe Lautstärkevorgaberegel, beispielsweise durch eine Kennlinie bzw. eine Tabelle, angehoben. Der Nachteil dabei ist, dass insbesondere in Kraftfahrzeugen, die als Entertainment-Audioquelle ein Top-Hifi-Gerät enthalten, neben der fahrzeuggeschwindigkeitsabhängigen Lautstärkeanpassung parallel andere Equalizing- und Klangoptimierungsprozesse (Dynamikkompression) betrieben werden, die ebenfalls abhängig von der Fahrzeuggeschwindigkeit bzw. von Störgeräuschen sind. Dadurch kommt es zu dem Effekt, dass mit steigendem Störgeräusch bzw. mit steigender Fahrzeuggeschwindigkeit das frequenzmäßig eher breitbandige Audiosignal (z. B. Radio oder Musik-CD von 20 Hz bis 20 kHz) einer derartigen Entertainment-Audioquelle subjektiv schneller lauter wird als frequenzmäßig eher schmalbandige Audiosignale von Interrupt-Audioquellen (z. B. Warntöne, Telefon oder Navigationsansagen), die bei hohem Störgeräusch gegebenenfalls nicht mehr wahrgenommen werden können.The Development of the invention considered yet another aspect of volume adjustments in motor vehicles: In the prior art, the volume of all audio signals in one Motor vehicle with increasing noise through one and the same volume specification rule, for example, by a characteristic or a table, raised. Of the Disadvantage is that, especially in motor vehicles, as Entertainment audio source included a top hi-fi device, in addition to the vehicle speed-dependent volume adjustment parallel other equalization and sound optimization processes (dynamic compression) operated, which also depends on the vehicle speed or from noise. This leads to the effect that with increasing noise or with increasing vehicle speed the frequency more likely broadband audio signal (eg radio or music CD from 20 Hz to 20 kHz) of such an entertainment audio source subjectively faster louder than in terms of frequency narrowband audio signals from interrupt audio sources (eg warning sounds, telephone or navigation announcements), which may no longer be perceived at high noise can be.
Gemäß einer Weiterbildung der Erfindung werden demnach die eher schmalbandigen Audiosignale, wie insbesondere die Warntöne (z. B. Gongs) mit steigendem Störgeräusch schneller bzw. steiler lauter, als die eher breitbandigen Audiosignale.According to one Development of the invention are therefore the rather narrow-band Audio signals, in particular the warning tones (eg gongs) with rising Noise faster or steeper louder than the more broadband audio signals.

Somit ist ein besserer Abgleich insbesondere der Interrupt-Audioquellen in Relation zu den Entertainment-Audioquellen möglich. Damit verbessert sich das Klangverhalten des Audiosystems im Hinblick auf die Beeinträchtigung durch Störgeräusche verschiedener Art.Consequently is a better match especially of the interrupt audio sources in relation to the entertainment audio sources possible. This improves the sound behavior of the audio system with regard to the impairment by noise different Art.
