Abstract
Description
Die Erfindung betrifft ein Akustiksystem für ein Fahrzeug, welches sitzplatzindividuell aktiviert werden kann, sowie ein Verfahren zum Betrieb eines solchen Systems nach den Oberbegriffen der Patentansprüche 1 und 5.The The invention relates to an acoustic system for a vehicle, which is seat-specific can be activated, and a method of operating such System according to the preambles of claims 1 and 5.
In Fahrzeugen kommt es aufgrund von Umgebungsgeräuschen häufig zu Beeinträchtigungen der Kommunikation zwischen den Insassen. Hierbei haben im Wesentlichen zwei Faktoren einen entscheidenden Einfluss. Der erste Faktor betrifft die Beeinflussung der Kommunikation durch Wind- und Fahrgeräusche, insbesondere verursacht durch Motor, Gebläse und Abrollen der Räder. Diese störende Geräuschquellen überlagern die akustische Information, welche im Rahmen der Kommunikation von einem bzw. zu einem Insassen transportiert werden soll. Der zweite Faktor betrifft die Position der Insassen zueinander. Abhängig von dieser Positionierung wird die Qualität der Kommunikation, insbesondere bei in Reihe hintereinander angeordneten Positionen der Insassen, besonders stark durch die Sprechrichtung (Signalausbreitung) und daraus resultierend durch entsprechende Signalverluste auf dem Übertragungsweg bestimmt werden.In Vehicles often experience adverse effects due to ambient noise Communication between the inmates. Here are essentially two factors have a decisive influence. The first factor concerns the influencing of the communication by wind and driving noise, in particular caused by engine, blower and rolling the wheels. These disturbing noise sources overlap the acoustic information, which in the context of the communication of to be transported to or to an occupant. The second Factor relates to the position of the occupants to each other. Depending on This positioning will increase the quality of communication, especially at in-line occupant positions, in particular strong due to the direction of speech (signal propagation) and as a result of corresponding signal losses are determined on the transmission path.
Um den ersten, die Insassenkommunikation beeinflussenden Faktor, die Überlagerung der akustischen Information durch Störgeräusche zu minimieren, sind so genannte Anti- Schallsysteme bekannt, welche ein dem störenden Geräuschsignal gegenphasiges akustisches Gegensignal am Ort eines Insassen erzeugen. Auf diese Weise soll erreicht werden, dass sich an diesem Ort das Gegensignal und das Störsignal nach Möglichkeit gegenseitig aufheben.Around the first factor affecting inmate communication, the overlay To minimize the acoustic information due to noise, so are called anti-sound systems known which one the disturbing noise signal generate antiphase acoustic counter signal at the location of an occupant. In this way it should be achieved that in this place the Counter signal and the interference signal if possible cancel each other out.
Derartige
Anti-Schallsysteme für
Kraftfahrzeuge werden in dem deutschen Patent
Um
aber sowohl den ersten als auch den zweiten die Insassenkommunikation
beeinflussenden Faktor zu minimieren ist ein System von notwendig,
wie dies beispielsweise mit dem deutschen Patent
Ausgehend von diesem Stand der Technik ist es die Aufgabe der Erfindung ein derartiges sitzplatzindividuelles Kommunikationssystem weiter zu bilden, um die Qualität der Insassenkommunikation noch weiter zu verbessern.outgoing From this prior art, it is the object of the invention such seat-individual communication system continues to make up for the quality the inmate communication even further.
Die Aufgabe wird durch ein Akustiksystem und ein Verfahren zum Betrieb dieses Akustiksystems mit den Merkmalen der Patentansprüche 1 und 5 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung werden durch die nachgeordneten Patentansprüche beschrieben.The Task is by an acoustic system and a method of operation this acoustic system with the features of claims 1 and 5 solved. Advantageous embodiments and further developments of the invention will be described by the subordinate claims.
Bei dem Akustiksystem für ein Fahrzeug sind einzelnen Sitzpositionen als Akustikeinheit wenigstens ein Lautsprecher und ein Mikrofon zugeordnet. Dabei sind die Akustikeinheiten der Sitzpositionen über Pegelwaagen und Echokompensatoren so miteinander gekoppelt, dass es den Fahrzeuginsassen möglich ist, über dieses gekoppelte System miteinander zu kommunizieren. In erfinderischer Weise ist nun ein Mittel vorgesehen, durch welches die Akustikeinheiten einzelner Sitzpositionen aktiviert und deaktiviert werden können.In the acoustic system for a vehicle, individual seating positions as an acoustic unit are assigned at least one loudspeaker and a microphone. In this case, the acoustic units of the seating positions are coupled to one another via level balances and echo compensators in such a way that it is possible for the vehicle occupants to communicate with one another via this coupled system. In an innovative way now provided a means by which the acoustic units of individual seating positions can be activated and deactivated.
Auf diese vorteilhafte Weise lässt sich somit die Anzahl der miteinander gekoppelten Akustikeinheiten bedarfsgerecht verändern. Insbesondere wird es möglich diejenigen Akustikeinheiten zu deaktivieren, welche Sitzpositionen zugeordnet sind, auf welchen sich keine Person befindet. Da hierdurch nicht notwendige Lautsprecherausgaben vermieden werden ergibt sich eine Reduzierung von akustischen Störsignalen im Innenraum des Fahrzeuges. Zusätzlich wirkt sich die Deaktivierung der nicht benötigten Mikrofone günstig aus, da sich der Signaleintrag in die Signalregelung des Akustiksystems verringert. Somit ergibt sich in besonders vorteilhafter Weise eine gegenüber dem Stand der Technik wesentlich stabilere und somit verbesserte Signalregelung. Hierdurch wird insbesondere die Kommunikationsqualität deutlich verbessert.On this advantageous way lets Thus, the number of coupled together acoustic units change as needed. In particular, it becomes possible to disable those acoustic units, which seating positions are assigned, on which there is no person. Because of this unnecessary speaker outputs are avoided a reduction of acoustic noise in the interior of the Vehicle. additionally the deactivation of the unnecessary microphones has a favorable effect, because the signal entry in the signal control of the acoustic system reduced. This results in a particularly advantageous manner across from the prior art much more stable and thus improved Signal control. As a result, in particular the communication quality is clear improved.
Das Mittel zur Aktivierung und Deaktivierung der Akustikeinheiten steht bevorzugt mit einem Mittel zur Sitzbelegungserkennung in Verbindung. Hierbei kann es sich beispielsweise um in den Fahrzeugsitzen integrierte Gewichtssensoren handeln. Andererseits ist es aber sehr wohl auch denkbar zur Sitzbelegungserkennung das Anlegen des Sicherheitsgurtes zu erfassen (beispielsweise über einen Tastmechanismus im Gurtschloss oder der Gurtumlenkrolle). Derartige Sensorinformation wird in modernen Kraftfahrzeugen meist bereits über den internen Fahrzeug-Datenbus als Information vor und kann somit ohne großen Aufwand dem Akustiksystem zur Weiterverarbeitung zur Verfügung gestellt werden.The Means for activating and deactivating the acoustic units preferably with a means for seat occupancy detection in conjunction. This may for example be integrated in the vehicle seats Weight sensors act. On the other hand, it is very well conceivable for seat occupancy recognition, the application of the seat belt to capture (for example, over a feeler mechanism in the buckle or the Gurtumlenkrolle). Such sensor information is usually in modern motor vehicles already over the internal vehicle data bus as information before and can thus without huge Expenditure made available to the acoustic system for further processing become.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung umfasst das Mittel zur Aktivierung und Deaktivierung der Akustikeinheiten ein manuelles (Tastatur) oder sprachbedienbares Eingabemittel, über das Sitzpositionen einzeln oder individuell ausgewählt werden können. Hierdurch wird es gewinnbringend möglich, ohne Sitzplatz individuelle Sensoren eine Auswahl von zu aktivierenden bzw. zu deaktivierenden Akustikeinheiten vorzunehmen.In a further advantageous embodiment of the invention the means for activating and deactivating the acoustic units a manual (keyboard) or voice-operated input means via which Seat positions can be selected individually or individually. hereby will it be profitable, without seating individual sensors a choice of to be activated or to be deactivated acoustic units.
Die Akustikeinheit so ausgestaltet sein, dass das manuelle bzw. sprachbediente Eingabemittel alternativ zu der automatischen Sitzplatzerkennung verwendet wird. Gewinnbringend ist es aber sehr wohl denkbar, beide Aktivierungs- und Deaktivierungsmittel parallel zu verwenden. Dabei ist es vorteilhaft, wenn das Zusammenspiel dieser beiden Komponenten so gestaltet ist, dass eine Aktivierung bzw. Deaktivierung über das manuelle bzw. sprachbediente Eingabemittel mit höherer Priorität als die automatische Sitzplatzerkennung behandelt wird. So wird es beispielsweise ermöglicht, dass die Akustikeinheit eines Sitzplatzes auf welchem sich ein Kleinkind in einer dafür geeigneten Transportschale mit einem Sicherheitsgurt gesichert befindet, durch den Fahrzeugführer deaktiviert wird. So kann das Kleinkind vor ungewollter akustischer Beschallung geschützt werden. Auch ist es denkbar, dass bei der Nutzung des Akustiksystems als Element einer Freisprecheinrichtung zur Kommunikation mit einer außerhalb des Fahrzeuges befindlichen Person, die Kommunikationsqualität dadurch verbessert wird, dass nur die dem kommunizierenden Insassen zugeordnete Akustikeinheit aktiv geschaltet beleibt; dies kann sich vor allem bei einem stark gestörten Funkkommunikationskanal als hilfreich erweisen.The Acoustic unit be designed so that the manual or speech-operated Input means used as an alternative to the automatic seat recognition becomes. However, it is very possible to profit from both activation and deactivating means in parallel. It is advantageous if the interaction of these two components is designed that activation or deactivation via the manual or voice-operated Input means with higher priority is treated as the automatic seat recognition. So will for example, it allows that the acoustic unit of a seat on which a toddler in one for that suitable transport tray is secured with a safety belt, by the driver is deactivated. Thus, the toddler can prevent unwanted acoustic Sound protected become. It is also conceivable that when using the acoustic system as an element of a handsfree device for communicating with a outside the vehicle person, the communication quality thereby is improved, that only those assigned to the communicating inmates Acoustic unit active switched; This is especially true in a badly disturbed Radio communication channel prove to be helpful.
In besonders vorteilhafter Weise lässt sich die erfindungsgemäße Akustikeinheit als Teil eines Insassenkommunikationssystem (In-Car-Communication-System), eines Telefonkonferenzsystems, als von unterschiedlichen Sitzplätzen wirkendes Sprachbediensystem oder zur individuellen Audiobeschallung verwenden.In particularly advantageous manner the acoustic unit according to the invention as part of an in-car communication system, of a conference call system, as acting from different seats Voice control system or for individual audio sound use.
