Description

Technisches Gebiet:Technical area:

Die Erfindung betrifft eine Vorrichtung zur Geräuschkompensation in einem Kraftfahrzeug mit einer Empfangseinrichtung, die auftretende Geräusche erfasst, mit einer Signalerzeugungseinrichtung, die auf der Grundlage der erfassten Geräusche wenigstens ein Signal erzeugt und mit wenigstens einem Lautsprecher, der unter Zugrundelegung des Signals Auslöschungsschallwellen erzeugt und ins Fahrzeuginnere abstrahlt, die gegenüber den Schallwellen der auftretenden Geräusche phasenverschoben sind.The invention relates to a device for noise compensation in a motor vehicle with a receiving device that detects occurring noises, with a signal generating device that generates at least one signal based on the detected noise and with at least one speaker, which generates on the basis of the signal Auslöschungsschallwellen and into the vehicle interior radiates out of phase with the sound waves of the noises occurring.

Stand der Technik:State of the art:

In den vergangenen Jahrzehnten ist der Ausbau von Parkplätzen, insbesondere an den Autobahnen, nicht im gleichen Maße gewachsen, wie der Straßenverkehr. Aus diesem Grund finden vor allem Fernfahrer immer seltener einen ruhigen Standplatz für ihre Ruhezeiten. Oft stehen die Fahrzeuge in Zu- und Ausfahrten von Rasthöfen oder auf dem Standstreifen der Autobahn. Zudem sind insbesondere in Deutschland, im Gegensatz zu anderen Ländern,- die LKW-Parkplätze äußerst ungünstig angeordnet, da die LKW-Parkplätze der Autobahn zugewandt sind, während die PKW-Parkplätze im größeren Abstand zur Fahrbahn angeordnet sind.In recent decades, the expansion of parking lots, especially on the motorways, has not grown to the same extent as road traffic. For this reason, especially long-haul drivers are less and less likely to find a quiet spot for their rest periods. Often the vehicles are in entrances and exits of restraints or on the hard shoulder of the highway. In addition, especially in Germany, unlike other countries, - the truck parking arranged extremely unfavorable, since the truck parking areas facing the highway, while the car parking spaces are located at a greater distance to the roadway.

In Bezug auf das zuvor geschilderte Problem ist zu berücksichtigen, dass Lärm einen der größten Stressfaktoren darstellt, da er sich negativ auf das vegetative Nervensystem auswirkt. Müdigkeit, Konzentrationsmangel, Nervosität und Gereiztheit sind die Folgen. Darüber hinaus führt ständige, auch unterschwellige Lärmeinwirkung zu Dauerschäden des Gehörs. Um diesem Problem entgegenzuwirken, sind Einrichtungen mit aktiver Lärmkompensation bekannt, die auf dem Prinzip des phaseninversen Schalls basieren. Bei einer derartigen aktiven Schallkompensation werden am Schalleinwirkungsort, insbesondere im Bereich des Ohres, die dort auftretenden Schallwellen mittels eines Schallaufnehmers in Form eines Mikrophons zunächst aufgenommen und einem Filter zu einer 180°-Phasenverschiebung zugeführt. Die phasenverschobenen Schallwellen werden schließlich über einen Lautsprecher ausgesendet, so dass sich die aufgenommenen und die hierzu phasenverschobenen Schallwellen zumindest zum größten Teil auslöschen. Mit einer derartigen aktiven Lärmkompensationseinrichtung kann vor allem im unteren Frequenzbereich eine Lärmreduzierung von mehr als 15 dB erreicht werden, wobei eine Lärmreduzierung um 10 dB subjektiv bereits als Halbierung der Lautstärke wirkt.Regarding the problem described above, it has to be taken into account that noise is one of the biggest stress factors as it has a negative effect on the autonomic nervous system. Fatigue, lack of concentration, nervousness and irritability are the consequences. In addition, constant, even subliminal noise effects permanent damage to the hearing. To counteract this problem, devices with active noise compensation are known, which are based on the principle of phase-inverse sound. With such an active sound compensation, the sound waves occurring there are first recorded at the sound impact location, in particular in the region of the ear, by means of a sound pickup in the form of a microphone and fed to a filter for a 180 ° phase shift. The phase-shifted sound waves are finally transmitted via a loudspeaker, so that the recorded and the phase-shifted sound waves extinguish, at least for the most part. With such an active noise compensation device, especially in the lower frequency range, a noise reduction of more than 15 dB can be achieved, whereby a noise reduction of 10 dB subjectively already acts as a halving of the volume.

Die aktive Lärmkompensation wird unterdessen bereits in verschiedenen Bereichen eingesetzt. So sind etwa seit einigen Jahren Kopfhörer mit aktiver Lärmkompensation erhältlich, die beispielsweise im Bereich von Flugzeugen sowohl im Cockpit als auch im Passagierraum eingesetzt werden.In the meantime, active noise compensation is already being used in various areas. For example, headphones with active noise compensation have been available for some years and are used, for example, in the area of aircraft in both the cockpit and the passenger compartment.

Darüber hinaus ist aus der WO 90109655 eine aktive Fahrzeuginnenraum-Geräuschkompensation bekannt, mit der insbesondere vom Fahrzeugmotor ausgehende Geräusche im Fahrzeuginnenraum kompensiert werden sollen. Die beschriebene Anordnung erzeugt ein elektrisches Signal aus einem Referenzsignal, das unter anderem mit Hilfe eines Mikrophons, das ein von dem Motor kommendes Lärmfeld misst, erzeugt wird. Das aus dem Referenzsignal abgeleitete elektrische Signal wird verstärkt und gegenüber dem Lärmfeld um 180° phasenverschoben an den Lautsprecher angelegt, um ein das störende Geräusch mehr oder weniger neutralisierendes Gegenschallfeld auszustrahlen.In addition, from the WO 90109655 an active vehicle interior noise compensation known to be compensated in particular by the vehicle engine emanating noise in the vehicle interior. The described arrangement generates an electrical signal from a reference signal which is generated inter alia by means of a microphone which measures a noise field coming from the engine. The electrical signal derived from the reference signal is amplified and applied to the loudspeaker 180 ° out of phase with the loudspeaker, in order to emit a counter-sound field which more or less neutralises the interfering noise.

In Erweiterung des vorbeschriebenen Systems ist es beispielsweise aus der DE 10 2004 031 657 A1 bekannt, eine Geräuschkompensation nicht erst durchzuführen, wenn die Geräusche auftreten, sondern bereits, sobald Fahrzeuginsassen Schalter oder Fahrzeugkomponenten betätigen, die zukünftig entsprechende Geräusche verursachen werden. Bei dieser technischen Lösung wird bereits bei Betätigung eines Schalters, beispielsweise eines Scheibenwischerschalters, oder bei Ergreifen eines Türgriffes ein das nachfolgende Geräusch kompensierendes Schallwellenfeld erzeugt und in den Fahrzeuginnenraum abgestrahlt.In extension of the system described above, it is for example from the DE 10 2004 031 657 A1 It is known not to carry out a noise compensation until the noises occur, but already as soon as vehicle occupants actuate switches or vehicle components which will cause corresponding noises in the future. In this technical solution, a sound wave field compensating for the subsequent noise is generated already upon actuation of a switch, for example a windscreen wiper switch, or when a door handle is gripped, and radiated into the vehicle interior.

Selbstverständlich werden auch passive Schalldämmungen, wie sie beispielsweise aus der DE 102 31 509 B3 bekannt sind, im Bereich eines Kraftfahrzeugs, insbesondere im Bereich einer Nutzfahrzeugschlafkabine verbaut. Mit den bekannten passiven Schalldämmelementen kann allerdings nur eine begrenzte Absenkung des Innenraumgeräuschpegels erreicht werden. Vor allem bei Geräuschen mit tiefen Frequenzen ist die Schalldämmung eines Kraftfahrzeugs aufgrund der zugrundeliegenden physikalischen Gesetzmäßigkeiten begrenzt. Eine weitere Erhöhung der Schalldämmung hätte eine erhebliche Gewichtserhöhung einer Fahrzeugkarosserie, beispielsweise eines Nutzfahrzeugfahrerhauses, zur Folge. Eine derartige Gewichtserhöhung ist sowohl aus ökologischen als auch aus ökonomischen Gründen nicht umsetzbar.Of course, passive sound insulation, as for example from the DE 102 31 509 B3 are known, installed in the area of a motor vehicle, in particular in the field of a commercial vehicle sleeping cabin. With the known passive soundproofing elements, however, only a limited reduction of the interior noise level can be achieved. Especially with noises with low frequencies, the sound insulation of a motor vehicle is limited due to the underlying physical laws. A further increase in the sound insulation would result in a considerable increase in the weight of a vehicle body, for example a commercial vehicle cab. Such an increase in weight is not feasible for ecological as well as for economic reasons.

Ausgehend von den aus dem Stand der Technik bekannten technischen Lösungen sowie der zuvor geschilderten Problematik liegt der Erfindung die Aufgabe zugrunde, ein System zur Geräuschkompensation für den Fahrzeuginnenraum anzugeben, das dem Fahrzeugführer auch während der Ruhezeiten einen komfortablen Schlaf, der nicht durch Lärm gestört wird, ermöglicht. Das anzugebende System soll über einen verhältnismäßig einfachen Aufbau verfügen und bevorzugt auch in bereits im Fahrzeug vorhandene Systeme integrierbar sein. Weiterhin soll das System sowohl im Bereich von Nutzfahrzeugen, insbesondere Lastkraftwagen und Reiseomnibussen, als auch im Bereich anderer Fahrzeuge, wie beispielsweise in Wohnmobilen, einsetzbar sein.Based on the known from the prior art technical solutions and the above-described problem, the invention has for its object to provide a system for noise compensation for the vehicle interior, the driver during rest even a comfortable sleep that is not disturbed by noise, allows. The system to be specified should have a relatively simple structure and preferably also be integrated into existing systems in the vehicle. Furthermore, the system should be used both in the field of commercial vehicles, in particular trucks and travel buses, as well as in the field of other vehicles, such as motor homes.

Eine vorteilhafte Verwendung einer erfindungsgemäß ausgeführten Vorrichtung wird ferner im Anspruch 7 angegeben.The aforementioned object is achieved with a device according to claim 1. Advantageous developments of the invention are the subject of the dependent claims and are explained in more detail in the following description with partial reference to the figures.

Unter Schlafplatz eines Fahrzeugs wird hierbei im Allgemeinen ein Platz verstanden, an dem zumindest eine Person während der Fahrt oder in Ruhezeiten des Fahrzeugs schlafen und / oder sich ausruhen kann. Hierbei kann es sich entweder um einen Sitz handeln, der in eine zumindest teilweise Liegeposition überführbar ist, als auch um einen Schlafplatz, der im Bereich einer Schlafkabine angeordnet ist. Unter Schlafkabine wiederum wird sowohl der in einem Lastkraftwagen oder Omnibus vorgesehene Ruheraum für den Fahrer, als auch ein entsprechend ausgebildeter Raum in einem Wohnmobil verstanden.A sleeping space of a vehicle is generally understood to mean a place at which at least one person can sleep and / or rest while driving or while the vehicle is at rest. This can either be a seat that can be moved into an at least partially lying position, as well as a sleeping space that is located in the area of a sleeping cabin. Under sleeping cabin turn, both the intended in a truck or bus rest room for the driver, as well as a suitably trained space in a motorhome is understood.

Mit Hilfe der erfindungsgemäß ausgeführten Vorrichtung ist es auf bevorzugte Weise möglich, einer Person, die sich im Bereich des Schlafplatzes befindet, einen ruhigen, erholsamen Schlaf zu ermöglichen. Dies wird vor allem dadurch erreicht, dass innerhalb des Fahrzeugs wahmehmbare Geräusche, deren Geräuschursache sich entweder im und/oder außerhalb des Fahrzeugs befindet, detektiert werden und nach Auswertung der Geräusche durch einen Lautsprecher Schwallwellen in den Bereich des Schlafplatzes ausgesandt werden, die zu einer Kompensation der Geräusche aufgrund einer zumindest teilweisen Auslöschung der jeweiligen Schallwellen führen. Eine gegenseitige zumindest teilweise Auslöschung der Schallwellen wird hierbei auf bevorzugte Weise dadurch erreicht, dass die störenden Schallwellen und die Auslöschungsschallwellen in ihrer Phase gegeneinander verschoben werden, insbesondere um einen Phasenwinkel von 180°.With the help of the device according to the invention, it is possible in a preferred manner to allow a person who is in the area of the sleeping area, a peaceful, restful sleep. This is achieved above all by the fact that within the vehicle perceivable noise, the noise cause is either in and / or outside of the vehicle are detected and emitted after evaluation of the noise by a speaker waves in the area of the sleeping area, which leads to a compensation the noise due to an at least partial extinction of the respective sound waves. A mutual at least partial extinction of the sound waves is achieved in a preferred manner in that the disturbing sound waves and the extinguishing sound waves are shifted in phase against each other, in particular by a phase angle of 180 °.

Zur Verwirklichung der Geräuschkompensation im Bereich des Schlafplatzes ist im Innenraum des Fahrzeugs zumindest eine als Mikrophon ausgeführte Empfangseinrichtung vorgesehen, mit der die auftretenden Geräusche aufgenommen werden, ein entsprechendes Eingangsignal an eine Signalerzeugungseinheit gesandt wird und die Signalerzeugungseinheit ihrerseits ein Ausgangssignal generiert, auf dessen Grundlage wenigstens ein Lautsprecher Auslöschungsschallwellen zur Kompensation der im Fahrzeuginnenraum auftretenden Geräusche erzeugt. Gemäß der Erfindung ist wenigstens ein Lautsprecher im Fahrzeuginnenraum derart angeordnet, dass die Auslöschungsschallwellen in einen Bereich eines Schlafplatzes, insbesondere in einen Bereich eines in einer separaten Schlafkabine angeordneten Schlafplatzes, abgestrahlt werden. Unter einer separaten Schlafkabine ist hierbei vor allem ein Bereich des Fahrzeuginnenraums zu verstehen, der entweder durch eine feste Wand oder durch einen Vorhang zumindest zeitweise gegenüber dem Fahrerarbeitsplatz abtrennbar sein. Auf besonders geeignete Weise ist der wenigstens eine Lautsprecher derart angeordnet, dass die Auslöschungsschallwellen zumindest in den Kopfbereich, also den Bereich, in dem sich üblicherweise der Kopf einer ruhenden bzw. schlafenden Person befindet, abgestrahlt werden.To realize the noise compensation in the area of the sleeping area, at least one receiving device designed as a microphone is provided in the interior of the vehicle with which the occurring noises are recorded, a corresponding input signal is sent to a signal generation unit and the signal generation unit in turn generates an output signal on the basis of which at least one Speaker extinguishing sound waves generated to compensate for the noise occurring in the vehicle interior. According to the invention, at least one loudspeaker in the vehicle interior is arranged in such a way that the extinguishing sound waves are radiated into an area of a sleeping space, in particular into a region of a sleeping space arranged in a separate sleeping cabin. Under a separate sleeping compartment here is mainly an area of the vehicle interior to be understood, which can be separated either by a solid wall or by a curtain at least temporarily against the driver's workplace. In a particularly suitable manner, the at least one loudspeaker is arranged in such a way that the extinguishing sound waves are radiated at least into the head region, that is to say the region in which the head of a person sleeping or sleeping is usually located.

Eine derart kombinierte Mikrophon-Lautsprecher-Einheit lässt sich auf vorteilhafte Weise im Bereich des Schlafplatzes, insbesondere im Kopfbereich, also dem Bereich des Schlafplatzes, an dem eine Person üblicherweise den Kopf bettet, angeordnet werden. In diesem Zusammenhang ist es denkbar, eine derartige Einheit entweder mit Hilfe entsprechender Befestigungsmittel an der Innenwand zu befestigen oder aber in diese zu integrieren.In an advantageous embodiment of the invention it is provided that the receiving device and the speaker are integrated in a microphone-speaker unit.

In this connection, it is conceivable to fasten such a unit to the inner wall either by means of appropriate fastening means or to integrate it into this.

Wie bereits eingangs ausgeführt worden ist, stellt eine vorteilhafte Anordnung des erfindungsgemäß vorgesehenen Lautsprechers, die Platzierung im Bereich einer Schlafkoje, vorzugsweise der Schlafkoje eines Nutzfahrzeugs, dar. Der Lautsprecher wird vorteilhafter Weise derart angeordnet, dass die Auslöschungsschallwellen in den Kopfbereich der Schlafkoje, also des Liegeplatzes, ausgesandt werden.As already mentioned, an advantageous arrangement of the loudspeaker according to the invention, the placement in the area of a bunk, preferably the bunk of a commercial vehicle, represents. The speaker is advantageously arranged such that the extinguishing sound waves in the head area of the bunk, so the Berth, to be sent out.

In einer weiteren besonderen Ausführungsform der Erfindung wird als wenigstens ein Lautsprecher zur Aussendung von Auslöschungsschallwellen ein Lautsprecher verwendet, mit dem auch übliche Audioklänge erzeugt werden können. In diesem Zusammenhang bietet es sich an, Lautsprecher, die an eine Musik- und / oder Femsehanlage des Fahrzeugs gekoppelt sind, für die erfindungsgemäß ausgeführte Vorrichtung zur Geräuschkompensation zu verwenden.In a further particular embodiment of the invention, a loudspeaker is used as at least one loudspeaker for emitting extinction sound waves, with which standard audio sounds can also be generated. In this context, it makes sense to use speakers which are coupled to a music and / or television system of the vehicle for the device according to the invention carried out for noise compensation.

Auf vorteilhafte Weise bietet es sich ferner an, den zur Geräuschkompensation verwendeten Lautsprecher an ein Weck- und / oder Alarmsystem anzubinden. Auf diese Weise ist es möglich, einen Fahrer, der im Bereich des Liegeplatzes schläft, auf eine Gefahr, beispielsweise ein Feuer oder die Überschreitung einer Kühltemperatur in einem Kühlauflieger, hinzuweisen und / oder den Fahrer zu einer gewünschten Weckzeit zu wecken.Advantageously, it also makes sense to connect the speaker used for noise compensation to a wake-up and / or alarm system. In this way, it is possible for a driver who sleeps in the area of the berth to indicate a danger, for example a fire or the exceeding of a cooling temperature in a refrigerated trailer, and / or to wake the driver to a desired wake-up time.

Mit Hilfe der erfindungsgemäßen Vorrichtung zur Geräuschkompensation, die üblicherweise mit passiven Schalldämmungselementen innerhalb der Fahrzeugwand kombiniert wird, wird einem Fahrzeugführer ein ruhiger Schlafplatz, vorzugsweise im Fahrerhaus eines Nutzfahrzeugs, bereitgestellt. Diese Maßnahme stellt insbesondere sicher, dass der Fahrer während seiner Ruhepausen einen erholsamen Schlaf findet und bei Wiederaufnahme der Fahrt ausreichend erholt ist.With the aid of the noise compensation device according to the invention, which is usually combined with passive sound insulation elements within the vehicle wall, a driver is provided with a quiet sleeping space, preferably in the cab of a commercial vehicle. This measure ensures, in particular, that the driver finds a restful sleep during his rest breaks and is sufficiently recovered when resuming the ride.

Im Folgenden wird die Erfindung ohne Beschränkung des allgemeinen Erfindungsgedankens anhand von Figur näher erläutert. Es zeigen:

  • Fig. 1: Schematische Darstellung eines Schlafplatzes im Kraftfahrzeug mit Geräusch-
    kompensationsvorrichtung in einer Seitenansicht;
  • Fig. 2.: Schematische Darstellung eines Schlafplatzes im Kraftfahrzeug mit Geräusch- kompensationsvorrichtung in einer Draufsicht.
In the following the invention without further restriction of the general inventive concept will be explained in more detail with reference to FIG. Show it:
  • Fig. 1 : Schematic representation of a sleeping place in the motor vehicle with noise
    compensation device in a side view;
  • Fig. 2 .: Schematic representation of a sleeping place in the motor vehicle with noise compensation device in a plan view.

Die Figur 1 zeigt in einer Seitenansicht die Integration einer Vorrichtung zur Geräuschkompensation in einem Nutzfahrzeugfahrerhaus 1. In dem dargestellten Nutzfahrzeugfahrerhaus ist im Bereich des Fahrerschlafplatzes 11 eine Schlafliege 4 vorgesehen, die quer zur Fahrtrichtung hinter dem Fahrer- 5 sowie dem Beifahrersitz angeordnet ist und sich in ausgeklapptem Zustand befindet. Sowohl im Bereich der Rückenlehne 12 des Fahrersitzes 5 als auch gegenüberliegend im Bereich der Fahrerhausrückwand 9 sind jeweils Lautsprecher 7 vorgesehen. An den Lautsprechem 7 sind darüber hinaus Mikrophone 10 derart angeordnet, dass die Lautsprecher 7 gemeinsam mit den Mikrophonen 10 jeweils eine kompakte Mikrophon-Lautsprecher-Einheit darstellen.The FIG. 1 shows in a side view the integration of a device for noise compensation in a commercial vehicle cab 1. In the illustrated commercial vehicle cab a sleeping berth 4 is provided in the driver's sleeping area 11, which is arranged transversely to the direction behind the driver 5 and the passenger seat and is in the unfolded state , Both in the area of the backrest 12 of the driver's seat 5 and opposite in the area of the cab rear wall 9 each speaker 7 are provided. In addition, microphones 10 are arranged on the loudspeakers 7 in such a way that the loudspeakers 7 together with the microphones 10 each represent a compact microphone loudspeaker unit.

Mit Hilfe der Mikrophone 10 werden die im Bereich des Fahrerschlafplatzes 11 auftretenden Geräusche erfasst und entsprechende Signale an eine Signalerzeugungseinheit 8 übermitteln. Die Signalerzeugungseinheit 8 erzeugt auf der Grundlage der Eingangssignale wenigstens ein Ausgangssignal, auf dessen Grundlage die Lautsprecher 7 Auslöschungsschallwellen erzeugen, die derart gegenüber den Schallwellen der auftretenden Geräusche phasenverschoben sind, dass die Schallwellen sich gegenseitig auslöschen. Hierzu sind die Auslöschungsschallwellen in ihrer Phase um 180° gegenüber der Phase der Schallwellen der auftretenden Geräusche verschoben. Die um 180° phasenverschobenen Auslöschungsschallwellen werden mittels der Lautsprecher 7 in den Bereich des Schlafplatzes 11 abgestrahlt, in dem sich üblicherweise der Kopf 6 eines schlafenden oder ruhenden Fahrzeuginsassen befindet. Selbstverständlich ist es denkbar, das beschriebene Geräuschkompensationssystem bei einer Doppelliegenanordnung, also bei zwei übereinander angeordneten Liegen 4, sowohl im Bereich der unteren Liege als auch ergänzend oder alternativ im Bereich der oberen Liege vorzusehen.With the help of the microphones 10, the noises occurring in the area of the driver's sleeping place 11 are detected and transmit corresponding signals to a signal generating unit 8. The signal generating unit 8 generates, on the basis of the input signals, at least one output signal on the basis of which the loudspeakers 7 generate canceling sound waves which are out of phase with the sound waves of the noises occurring so that the sound waves cancel each other out. For this purpose, the extinction sound waves are shifted in their phase by 180 ° with respect to the phase of the sound waves of the noises occurring. The extinction sound waves phase-shifted by 180 ° are radiated by means of the loudspeakers 7 into the area of the sleeping place 11, in which the head 6 of a sleeping or resting vehicle occupant is usually located. Of course, it is conceivable to provide the described noise compensation system in a double-lying arrangement, that is, in the case of two superimposed couches 4, both in the area of the lower couch and additionally or alternatively in the area of the upper couch.

Zusätzlich zu den Mikrophonen 10, den Lautsprechem 7 und der Signalerzeugungseinheit 8, die Mittel zur aktiven Kompensation von Geräuschen darstellen, die im Bereich des Fahrerschlafplatzens 11 auftreten, verfügen die Fahrerhausrückwand 2, die Seitenwände 9 sowie der Fahrerhausboden 3 auf ihrer Innenseite über passive Schalldämmelemente. Diese Schalldämmelemente 15 sind derart ausgeführt, dass sie Schallwellen einer bestimmten Frequenz und Amplitude absorbieren können.In addition to the microphones 10, the loudspeakers 7 and the signal generating unit 8, which represent means for actively compensating for noise occurring in the area of the driver's sleeping place 11, the cab rear wall 2, the side walls 9 and the cab floor 3 have passive sound insulation elements on their inside. These sound-absorbing elements 15 are designed such that they can absorb sound waves of a specific frequency and amplitude.

Trotz dieser Maßnahmen zur passiven Schalldämmung kann hierdurch nur eine begrenzte Absenkung des Innengeräuschpegels erreicht werden. Insbesondere bei tiefen Frequenzen ist die Schalldämmung des Fahrerhauses aufgrund physikalischer Gesetzmäßigkeiten durch passive Schalldämmelemente 13 beschränkt. Weiterhin ist die Verstärkung der passiven Schalldämmelemente 13 nur begrenzt möglich, da das Fahrerhaus 1 auch im Hinblick auf sein Gewicht sowie das zur Verfügung gestellte Innenvolumen optimiert werden muss.Despite these passive noise control measures, only a limited reduction of the interior noise level can be achieved. Especially at low frequencies, the sound insulation of the cab is limited due to physical laws by passive sound insulation 13. Furthermore, the gain is passive Soundproofing 13 only limited possible, since the cab 1 must be optimized in terms of its weight and the provided inner volume.

Ergänzend ist zu einer besseren Veranschaulichung in Figur 2 der in Figur 1 in einer Seitenansicht dargestellte Fahrerschlafplatz 11 mit einem erfindungsgemäß ausgeführten System zur Geräuschkompensation in einer Draufsicht gezeigt. Das in Figur 2 dargestellte System entspricht im Übrigen in seiner technischen Ausführung dem im Zusammenhang mit Figur1 bereits erläuterten.In addition to a better illustration in FIG. 2 the in FIG. 1 shown in a side view driver's sleep 11 with a system according to the invention executed for noise compensation in a plan view. This in FIG. 2 shown system corresponds otherwise in its technical execution in connection with Figur1 already explained.

Die erfindungsgemäß eingesetzte Vorrichtung zur Geräuschkompensation kompensiert innerhalb des Fahrerhauses 1, insbesondere im Bereich des Fahrerschlafplatzes 11 auftretende Geräusche mit Hilfe des sogenannten Gegenschallprinzips. Wie die Figuren 1 und 2 zeigen, sind hierbei im Bereich der Schlafliege 4 in unmittelbarer Nähe des Kopfbereiches, also dort, wo der Fahrer üblicherweise seinen Kopf während des Ruhens oder Schlafens ablegt, Lautsprecher 7 vorgesehen, die Auslöschungsschallwellen aussenden, die Schallwellen der im Bereich des Fahrerschlafplatzes 11 auftretenden Geräusche zumindest weitgehend auslöschen.The noise compensation device used according to the invention compensates for noises occurring within the driver's cab 1, in particular in the area of the driver's sleeping place 11, with the aid of the so-called counter-noise principle. As the FIGS. 1 and 2 show are here in the area of the berth 4 in the immediate vicinity of the head area, ie where the driver usually puts his head while resting or sleeping, provided loudspeaker 7, send out the extinction sound waves, the sound waves of the noise occurring in the area of the driver's sleep 11 at least largely extinguish.

Die im Fahrzeuginnenraum auftretenden bzw. ohne Geräuschkompensation wahrnehmbaren Geräusche können ihre Ursache sowohl innerhalb als auch außerhalb des Fahrzeugs haben. Insbesondere Motorgeräusche, Verkehrslärm und / oder durch dieselbetriebene Kühlaggregate verursachter Lärm wirkt sich oftmals störend auf den Schlaf eines Fahrers, insbesondere eines Fernfahrers aus. Mit Hilfe des erfindungsgemäß ausgeführten Systems zur Geräuschkompensation werden derartige Störgeräusche zumindest weitgehend ausgelöscht.The noises occurring in the vehicle interior or perceptible without noise compensation can be caused both inside and outside the vehicle. In particular, engine noise, traffic noise and / or noise caused by diesel-powered refrigeration units often has a disturbing effect on the sleep of a driver, especially a truck driver. With the help of the inventively designed system for noise compensation such noise is at least largely extinguished.

Das den Figuren 1 und 2 zu entnehmende System zur Geräuschkompensation verfügt über zwei Mikrophon-Lautsprecher-Einheiten 7, 10 sowie eine Signalerzeugungseinheit 8, mit der das System gesteuert wird. Bei Bedarf können die Lautsprecher 7 des Geräuschkompensationssystems auch zur Audiowiedergabe in der Fahrerkabine, insbesondere im Bereich des Schlafplatzes, genutzt werden.That the FIGS. 1 and 2 To be taken out system for noise compensation has two microphone speaker units 7, 10 and a signal generating unit 8, with which the system is controlled. If required, the loudspeakers 7 of the noise compensation system can also be used for audio reproduction in the driver's cab, in particular in the area of the sleeping area.
