Stand der TechnikState of the art

Es ist aus dem Stand der Technik bekannt, Auspuffblenden zum Schutz und zur Verzierung von Auspuffrohren von Kraftfahrzeugen zu verwenden, wie unter anderem in der DE 10 2004 038 782 A1 und DE 10 2014 208 722 A1 angeführt ist. US2017/0133003 A1 offenbart ein solches System.It is known from the prior art to use exhaust covers to protect and decorate the exhaust pipes of motor vehicles, such as, inter alia, in US Pat DE 10 2004 038 782 A1 and DE 10 2014 208 722 A1 is listed. US2017 / 0133003 A1 discloses such a system.

Bei den aus dem Stand der Technik bekannten Auspuffblenden treten keine kontrolliert unterscheidbaren akustischen Effekte zusätzlich zu denen auf, welche durch das Kraftfahrzeug bei dessen Gebrauch erzeugt werden, wie zum Beispiel Motorgeräusche.In the case of the exhaust trims known from the prior art, there are no audible effects that can be distinguished in a controlled manner in addition to those that are generated by the motor vehicle when it is in use, such as engine noises for example.

Es ist daher Aufgabe der Erfindung, eine Auspuffblende bereitzustellen, mit welcher solche zusätzlichen akustischen Effekte kontrolliert erzeugt werden können, zum Beispiel Warnsignale für andere Verkehrsteilnehmer bei Beschleunigung oder Abbremsung des Kraftfahrzeugs oder Erkennungssignale für ein individuelles Kraftfahrzeug, z.B. ein motorspezifischer Sound. Es ist ferner Aufgabe der Erfindung, eine Auspuffanlage mit einer solchen Auspuffblende bereitzustellen. Es ist weiter Aufgabe der Erfindung, ein Verfahren zur Schallabgabe mit einer solchen Auspuffblende anzugeben.It is therefore the object of the invention to provide an exhaust cover with which such additional acoustic effects can be generated in a controlled manner, for example warning signals for other road users when the motor vehicle is accelerating or braking, or detection signals for an individual motor vehicle, e.g. an engine-specific sound. It is also an object of the invention to provide an exhaust system with such an exhaust screen.

Offenbarung der ErfindungDisclosure of the invention

Die erfindungsgemäße Auspuffblende für ein Kraftfahrzeug weist einen röhrenförmigen Inneneinsatz auf. Sie ist dadurch gekennzeichnet, dass sie mit einer ansteuerbaren Schallerzeugungseinrichtung zur Schallabgabe aus der Auspuffblende ausgestattet ist.The exhaust screen according to the invention for a motor vehicle has a tubular inner insert. It is characterized in that it is equipped with a controllable sound generating device for emitting sound from the exhaust aperture.

Vorteilhaft lassen sich durch eine Schallerzeugungseinrichtung Töne bzw. Schallwellen kontrolliert zusätzlich zu den Geräuschen bewirken, welche von dem Kraftfahrzeug selber während dessen Gebrauch erzeugt werden. Dadurch können akustische Effekte zum Beispiel zu einer Erhöhung der Sicherheit im Straßenverkehr hervorgebracht werden, unter anderem in Form von Warnsignalen. Die Schallerzeugungseinrichtung ist besonders bevorzugt in Form einer Lautsprechermembran ausgebildet. Für verschiedene Kraftfahrzeuge können verschiedene akustische Signale verwendet werden, sodass einzelne Kraftfahrzeuge anhand dieser Signale unterschieden werden können. Weiterhin kann der Klang bzw. "Sound" eines Motors verstärkt werden.In addition to the noises generated by the motor vehicle itself during its use, tones or sound waves can advantageously be produced in a controlled manner by a sound generating device. As a result, acoustic effects can be produced, for example, to increase safety in road traffic, among other things in the form of warning signals. The sound generating device is particularly preferably designed in the form of a loudspeaker diaphragm. Different acoustic signals can be used for different motor vehicles, so that individual motor vehicles are based on these signals can be distinguished. Furthermore, the sound or "sound" of an engine can be amplified.

Bei einer vorteilhaften Ausgestaltung der Auspuffblende ist der Inneneinsatz in Form eines Klangkörpers zur Schallabgabe ausgebildet. Die von der Schallerzeugungseinrichtung erzeugten Töne können dann in den Inneneinsatz geleitet und dort verstärkt und/oder fokussiert werden. Insbesondere können durch den Inneneinsatz und gegebenenfalls andere akustische Mittel wie weitere Verstärker Töne erzeugt werden, welche tief sind im Vergleich zu Geräuschen, welche das Kraftfahrzeug bei dessen Gebrauch erzeugt. Die Temperatur am Lautsprecher, dem Innneneinsatz und den weiteren akustischen Mitteln kann hierbei durch Luftströme in einem zum Funktionieren des Lautsprechers und der akustischen Mittel angemessenen Bereich gehalten werden.In an advantageous embodiment of the exhaust panel, the inner insert is designed in the form of a sound body for sound emission. The tones generated by the sound generating device can then be passed into the interior insert and amplified and / or focused there. In particular, through the indoor use and possibly other acoustic means such as further amplifiers, tones can be generated which are deep in comparison to noises which the motor vehicle generates when it is in use. The temperature on the loudspeaker, the inner insert and the other acoustic means can be kept in a range appropriate for the functioning of the loudspeaker and the acoustic means by means of air currents.

Vorteilhaft weist der Inneneinsatz eine Ausnehmung auf, insbesondere in Form einer Durchgangsausnehmung, in der die Schallerzeugungseinrichtung angeordnet ist. Dann kann der von der Schallerzeugungseinrichtung erzeugte Schall unmittelbar in den Inneneinsatz geleitet werden.The inner insert advantageously has a recess, in particular in the form of a through recess, in which the sound generating device is arranged. The sound generated by the sound generating device can then be passed directly into the interior insert.

In einer weiteren Ausgestaltung weist die Auspuffblende zur mittelbaren oder unmittelbaren Spannungsversorgung der Schallerzeugungseinrichtung eine Batterie und/oder einen Akkumulator auf. Hierdurch kann eine unabhängige Versorgung der Schallerzeugungseinrichtung mit elektrischer Energie sichergestellt werden.In a further embodiment, the exhaust cover has a battery and / or an accumulator for the direct or indirect power supply of the sound generating device. In this way, an independent supply of the sound generating device with electrical energy can be ensured.

Bei einer weiteren Ausführungsform weist die Auspuffblende zur mittelbaren oder unmittelbaren Spannungsversorgung der Schallerzeugungseinrichtung einen Wandler zur Umwandlung von Wärme in elektrische Spannung auf, insbesondere in Form eines Piezoelements. Hierdurch kann die im Kraftfahrzeug während dessen Benutzung entstehende Wärme, zum Beispiel Abgaswärme, zur Bereitstellung elektrischer Energie für die Schallerzeugungseinrichtung verwendet werden.In a further embodiment, the exhaust panel has a converter for converting heat for the direct or indirect voltage supply of the sound generating device in electrical voltage, in particular in the form of a piezo element. As a result, the heat generated in the motor vehicle during its use, for example exhaust gas heat, can be used to provide electrical energy for the sound generating device.

Vorteilhaft weist die Auspuffblende eine Steuereinheit zum Ansteuern der Schallerzeugungseinrichtung auf, wobei die Steuereinheit vorzugsweise ein digitales Abspielgerät aufweist. Dann können durch die Schallerzeugungseinrichtung erzeugte Töne gezielt vorab ausgewählt und gespeichert werden.The exhaust cover advantageously has a control unit for controlling the sound generating device, the control unit preferably having a digital playback device. Then tones generated by the sound generating device can be specifically selected in advance and stored.

In einer vorteilhaften Ausgestaltung ist die Steuereinheit durch eine Funk-Fern-Verbindung, insbesondere per WLAN, ansteuerbar. Dann können die Töne, welche durch die Schallerzeugungseinrichtung erzeugt werden, von außerhalb der Auspuffblende und/oder des Kraftfahrzeugs gesendet werden bzw. von einem Nutzer von einer äußeren Datenquelle heruntergeladen werden.In an advantageous embodiment, the control unit can be controlled by a radio remote connection, in particular by WLAN. The tones which are generated by the sound generating device can then be sent from outside the exhaust cover and / or the motor vehicle or downloaded by a user from an external data source.

Bei einer weiteren Ausführungsform weist die Auspuffblende einen Vibrationssensor auf, insbesondere am Inneneinsatz. Dadurch lassen sich die Töne bzw. der Schall in Abhängigkeit von der Vibration des Inneneinsatzes einstellen. Durch diese Vibration lässt sich eine Kopplung des erzeugten Schalls an die Geschwindigkeit des Kraftfahrzeugs bewirken.In a further embodiment, the exhaust cover has a vibration sensor, in particular on the inner insert. This allows the tones or the sound to be set depending on the vibration of the indoor insert. This vibration allows the generated sound to be coupled to the speed of the motor vehicle.

Vorteilhaft weist die Auspuffblende, insbesondere am Inneneinsatz, einen Gasflusssensor auf. Der Gasflusssensor kann zur Luftmassenmessung und/oder zur Luftvolumenmessung ausgebildet sein. Dadurch lassen sich die Töne bzw. der Schall in Abhängigkeit von dem Abgasfluss durch die Auspuffblende einstellen. Auch durch den Fluss bzw. Volumenstrom des Abgases aus dem Motor lässt sich eine Kopplung des erzeugten Schalls an die Geschwindigkeit des Kraftfahrzeugs bewirken.The exhaust panel advantageously has a gas flow sensor, in particular on the inner insert. The gas flow sensor can be designed for air mass measurement and / or for air volume measurement. In this way, the tones or the sound can be adjusted as a function of the exhaust gas flow through the exhaust cover. Also by the flow or volume flow of the Exhaust gas from the engine can be used to couple the generated sound to the speed of the motor vehicle.

Eine Auspuffanlage weist ein Auspuffrohr und eine an das Auspuffrohr montierte erfindungsgemäße Auspuffblende auf. Vorteilhaft kann eine solche Auspuffanlage eines Kraftfahrzeugs kontrolliert akustische Effekte zusätzlich zu den bei Gebrauch des Fahrzeugs erzeugten Geräuschen bewirken. Der Klang des Motors eines Kraftfahrzeugs kann verstärkt und/oder modifiziert werden. Hierdurch können zum Beispiel andere Verkehrsteilnehmer vor einer Beschleunigung oder Abbremsung des Kraftfahrzeugs gewarnt werden. Die abgegebenen Töne können für einzelne Kraftfahrzeuge individuell gestaltet werden.An exhaust system has an exhaust pipe and an exhaust screen according to the invention mounted on the exhaust pipe. Such an exhaust system of a motor vehicle can advantageously produce controlled acoustic effects in addition to the noises generated when the vehicle is in use. The sound of the engine of a motor vehicle can be amplified and / or modified. In this way, for example, other road users can be warned of acceleration or deceleration of the motor vehicle. The tones emitted can be designed individually for individual vehicles.

Bei einem Verfahren zur Schallabgabe an einer Auspuffblende wird an dieser Auspuffblende über eine angesteuerte Schallerzeugungseinrichtung Schall abgegeben. Mit dem Verfahren wird vorzugsweise der Klang des Motors eines Kraftfahrzeugs verstärkt und/oder modifiziert. Durch von der Schallerzeugungseinrichtung abgegebene akustische Signale kann die Verkehrssicherheit erhöht werden, wenn ein Kraftfahrzeug, welches über eine solche Schallerzeugungseinrichtung verfügt, beschleunigt oder abbremst.In a method for emitting sound at an exhaust screen, sound is emitted at this exhaust screen via a controlled sound generating device. The method is preferably used to amplify and / or modify the sound of the engine of a motor vehicle. Traffic safety can be increased by the acoustic signals emitted by the sound generating device when a motor vehicle which has such a sound generating device accelerates or brakes.

Bei einer vorteilhaften Ausgestaltung des Verfahrens erfolgt die Schallabgabe in Abhängigkeit von

  1. a) einer gemessenen Schwingung der Auspuffblende und/oder eines Teils der Auspuffblende; und/oder
  2. b) in Abhängigkeit von einem gemessenen Abgasfluss durch die Auspuffblende.
In an advantageous embodiment of the method, the sound is emitted as a function of
  1. a) a measured vibration of the exhaust screen and / or part of the exhaust screen; and or
  2. b) as a function of a measured exhaust gas flow through the exhaust aperture.

Vorteilhaft kann auf diese Weise die Schallabgabe an die Erhöhung bzw. Absenkung der Vibrationen der Auspuffblende und/oder des Abgasflusses und damit mittelbar an die Geschwindigkeit des Kraftfahrzeugs gekoppelt werden.In this way, the sound output to the increase or decrease in the vibrations of the exhaust aperture and / or the exhaust gas flow can be advantageous and thus indirectly linked to the speed of the motor vehicle.
