Abstract

The noise simulator/generator is fitted to a vehicle and is driven by a control which receives information on the speed of the vehicle. Sensors (13) monitor wheel speed, motor speed etc. and the control drives the noise generator to simulate engine noise corresponding to the speed of the vehicle. The noise is produced by loudspeakers inside and outside the vehicle. The noise patterns are stored on a CD or on an audio cassette. A selection of sound types is controlled by a microprocessor and by the driver selection. The system can be fitted to all types of vehicle including boats and aircraft.

Description

Die Erfindung betrifft eine Vorrichtung zur Imitation von Motor- und Fahrgeräuschen bei Kraftfahrzeugen.The invention relates to a device for imitation of engine and driving noises in motor vehicles.

Zunehmend werden Kraftfahrzeuge mit elektromotorischen Antrieben entwickelt. Diese Elektrofahrzeuge haben dan­ kenswerterweise eine recht geringe Geräuschemission. Diese geringe Geräuschemission, so anstrebsam sie sein mag, weist einen nicht zu unterschätzenden nachteili­ gen Sicherheitsaspekt auf. Diese Fahrzeuge sind nämlich so leise, daß sie von Passanten oder spielenden Kindern bei Annäherung nicht gehört werden. Insbesondere bei spiel enden Kindern sind Geräusche von sich nähernden Fahrzeugen als eine sich nähernde Gefahr im Unterbe­ wußtsein gespeichert. Dieses Unterbewußtsein ist mit einer entsprechenden Vorsicht gekoppelt. Nähert sich nun ein Fahrzeug fast ohne ein Fahrgeräusch, so wird es auch nicht oder zu spät wahrgenommen und es kann leicht zu Unfällen kommen. Motor vehicles with an electric motor are increasingly used Drives developed. These electric vehicles have dan notably a fairly low noise emission. This low noise emission, as ambitious as it is may have a disadvantage that should not be underestimated safety aspect. Because these vehicles are so quiet that it can be heard from passers-by or children playing not heard when approaching. Especially at Playing children are sounds of approaching Vehicles as an approaching danger in the lower sub awareness saved. This subconscious is with appropriate caution coupled. Approaches now a vehicle with almost no sound, so it will also not perceived or too late and it can easily accidents occur.  

Auch weisen Kraftfahrzeuge, insbesondere Personenkraftwagen, ein ganz spezifisches Fahr-, Auspuff- und Moto­ rengeräusch auf, das nicht unwesentlich für das Wohlbe­ finden des Fahrers und der Fahrzeuginsassen mit verant­ wortlich ist. Das Wohlbefinden des Fahrers wiederum trägt ganz wesentlich mit zur sicheren Beherrschung des Fahrzeuges und damit zur allgemeinen Verkehrssicherheit bei.Motor vehicles, in particular passenger vehicles, also have a very specific driving, exhaust and moto noise, which is not insignificant for the wellbeing find responsibility for the driver and the vehicle occupants is literal. The driver's well-being in turn contributes significantly to the safe mastery of the Vehicle and thus for general traffic safety at.

Aufgabe der vorliegenden Erfindung ist es, eine Vor­ richtung zu schaffen, mit der die Fahrgeräusche eines Fahrzeugs in einen besser wahrnehmbaren und das Wohlbe­ finden der Fahrzeuginsassen verbessernden Frequenzbe­ reich gebracht werden kann.The object of the present invention is to provide a create direction with which the driving noise of a Vehicle in a more noticeable and well-being find the vehicle occupant improving frequency can be brought rich.

Gelöst wird die Aufgabe dadurch, daß eine von der Fahr­ zeuggeschwindigkeit aktivierbare Meßvorrichtung vorge­ sehen ist, die Meßvorrichtung mit einem Geräuschgenera­ tor in Wirkverbindung steht und der Geräuschgenerator mit mindestens einer Geräuschabstrahlvorrichtung ver­ bunden ist.The task is solved in that one of the driving test speed activatable measuring device see the measuring device with a noise generator is in operative connection and the noise generator ver with at least one noise emitting device is bound.

Ferner kann es vorgesehen sein, daß eine drehzahlabhä­ gige Meßvorrichtung vorgesehen ist, die Meßvorrichtung mit einem Geräuschgenerator in Wirkverbindung steht und der Geräuschgenerator mit einer Geräuschabstrahlvor­ richtung verbunden ist.It can also be provided that a speed dependent Gige measuring device is provided, the measuring device is operatively connected to a noise generator and the noise generator with a noise emission direction is connected.

Durch diese Maßnahmen können drehzahl- und geschwindig­ keitsabhängige Geräuschfrequenzen abgestrahlt werden. Diese Geräuschfrequenzen werden in einem Frequenzbe­ reich wiedergegeben, der einerseits von der Umgebung als Gefahrensignal wahrgenommen wird und andererseits das Wohlbefinden der Fahrzeuginsassen steigert. Die in Abhängigkeit von der Drehzahl generierten Geräusch- und Klangfrequenzen des Geräuschgenerators werden mittels Innen- und/oder Außenlautsprecher wiedergegeben.These measures can speed and speed speed-dependent noise frequencies are emitted. These noise frequencies are in a frequency richly reproduced by the one hand from the surroundings is perceived as a danger signal and on the other hand increases the well-being of vehicle occupants. In the Dependence on the speed generated noise and  Sound frequencies of the noise generator are by means of Indoor and / or outdoor speakers reproduced.

Die Anwendung der vorliegenden Erfindung ist nicht nur auf Personenkraftwagen beschränkt. So können ebenfalls alle anderen, von einem Verbrennungsmotor, einem Elek­ tromotor, dem Wind, einem Pferdegespann, eine Dampfma­ schine oder in anderer Form angetriebenen Fahrzeuge wie z. B. Boote, Flugzeuge und Züge mit der Erfindung ausge­ rüstet werden.The application of the present invention is not only limited to passenger cars. So can also everyone else, from an internal combustion engine, an elec tromotor, the wind, a team of horses, a steam engine machines or in other forms powered vehicles such as e.g. B. boats, planes and trains with the invention be prepared.

Weitere vorteilhafte Maßnahmen sind in den Unteransprü­ chen beschrieben. Die Erfindung ist in den beiliegenden Zeichnungen dargestellt und wird nachfolgend näher be­ schrieben; es zeigt:Further advantageous measures are in the subclaims Chen described. The invention is in the accompanying Drawings are shown and will be closer wrote; it shows:

Fig. 1 ein Fahrzeug mit einer Meßvorrichtung, die über ein Drehzahlinformationsübertragungsmit­ tel mit einem Geräuschgenerator in Verbindung steht, der wiederum die generierten Geräu­ schinformationen über ein Geräuschinformati­ onsübertragungsmittel an Innen- und Außenlaut­ sprecher übermittelt und abstrahlt; Fig. 1 shows a vehicle with a measuring device, which is connected via a speed information transfer means with a noise generator, which in turn transmits and radiates the generated noise information via a noise information transmission means to the inside and outside speakers;

Fig. 2 den vorderen Bereich eines Fahrzeuges mit ei­ ner Antriebsmaschine, die ein Getriebe und ei­ ne Lichtmaschine antreibt, die über ein Dreh­ zahlinformationsübertragungsmittel mit einem Mikroprozessor-gesteuerten Geräuschgenerator in Verbindung stehen, der wiederum Informatio­ nen von einem Geräuschträger bezieht. Fig. 2 shows the front area of a vehicle with a drive engine that drives a transmission and an alternator that are connected via a speed information transmission means to a microprocessor-controlled noise generator, which in turn relates information from a noise carrier.

Das in der Fig. 1 beispielsweise dargestellte Kraft­ fahrzeug 10 weist eine Meßvorrichtung 14 auf, die mit unterschiedlichen rotierenden Bauteilen verbunden sind. Mögliche Bauteile sind beispielsweise die Laufräder 19, eine Lichtmaschine 20, eine Antriebsmaschine 11 oder ein Getriebe 23.The motor vehicle 10 shown in FIG. 1, for example, has a measuring device 14 , which are connected to different rotating components. Possible components are, for example, the impellers 19 , an alternator 20 , a drive machine 11 or a transmission 23 .

Die durch die Meßvorrichtung 14 ermittelten Informatio­ nen werden über ein Drehzahlinformationsübertragungs­ mittel 13 zu einem Geräuschgenerator 12 weiter gelei­ tet. Das Drehzahlinformationsübertragungsmittel 13 kann beispielsweise ein Metallkabel, ein Lichtleiter oder eine Funkübertragungsvorrichtung sein. Der Geräuschge­ nerator 12 wandelt die Drehzahlinformationen in ent­ sprechende Geräuschinformationen um.The information determined by the measuring device 14 is passed on via a speed information transmission means 13 to a noise generator 12 . The speed information transmission means 13 can be, for example, a metal cable, a light guide or a radio transmission device. The noise generator 12 converts the speed information into corresponding noise information.

Die Umwandlung der Geräuschinformationen kann durch ei­ nen Mikroprozessor 21 vorgenommen werden, der wiederum mit einem Geräuschträger 22 in Wirkverbindung steht. Auf dem Geräuschträger 22 sind in der Regel digitali­ sierte Geräusche, Klänge oder Töne unterschiedlicher Frequenzen und Frequenzbereiche gespeichert. Mögliche Formen des Geräuschträgers 22 sind nichtflüchtige RAM-Bausteine(SRAM), Compact Discs, oder digitale Bänder.The conversion of the noise information can be carried out by a microprocessor 21 , which in turn is in operative connection with a noise carrier 22 . On the sound carrier 22 digitized sounds, sounds or tones of different frequencies and frequency ranges are usually stored. Possible forms of the sound carrier 22 are non-volatile RAM chips (SRAM), compact discs, or digital tapes.

Bei einer Ausführungsform kann der Geräuschgenerator 12 mit einem Geräuschträger 22 in Wirkverbindung stehen, ohne daß die Geräusche durch einen Mikroprozessor mani­ puliert werden. Hierbei wird in Abhängigkeit von der Drehzahlinformation ein anderes Geräusch gewählt oder das Geräusch schneller abgespielt. Mögliche Ge­ räuschträger sind Compact Disks (CDs) oder Audio-Kassetten.In one embodiment, the noise generator 12 can be operatively connected to a noise carrier 22 without the noise being manipulated by a microprocessor. Depending on the speed information, a different sound is selected or the sound played back faster. Possible noise carriers are compact discs (CDs) or audio cassettes.

Die durch den Geräuschgenerator 12 erzeugten Geräu­ schinformationen werden mit Hilfe eines Geräuschinfor­ mationsübertragungsmittels 15 zu Lautsprechern 16 und/oder 17 übertragen. Die Lautsprecher können sowohl Innenlautsprecher 17, die ihre Schallwellen 18 in den Innenraum des Fahrzeugs 10 abstrahlen, als auch Außenlautsprecher 16 sein, die ihre Schallwellen 18 an die Umgebung abgeben.The sound information generated by the noise generator 12 is transmitted with the aid of a noise information transfer means 15 to speakers 16 and / or 17 . The loudspeakers can be both internal loudspeakers 17 , which emit their sound waves 18 into the interior of the vehicle 10 , and external loudspeakers 16 , which emit their sound waves 18 to the environment.

Es kann vorkommen, daß die imitierten Geräusche uner­ wünscht sind; dazu ist ein Schalter 24 vorgesehen, mit dem beispielsweise das Geräuschinformationsübertra­ gungsmittel 15 unterbrochen und damit die Geräuschab­ strahlung abgeschaltet werden kann. Auch die Lautstärke der abgestrahlten Schallwellen 18 kann mittels eines entsprechenden, nicht dargestellten Reglers variiert werden.It can happen that the imitated sounds are undesirable; for this purpose, a switch 24 is provided with which, for example, the noise information transmission means 15 can be interrupted and thus the noise radiation can be switched off. The volume of the emitted sound waves 18 can also be varied by means of a corresponding controller, not shown.

Um den das Wohlbefinden steigernde klanglichen Ge­ schmack einer Vielzahl von potentiellen Anwendern zu treffen, stellt der Geräuschgenerator 12 die Möglich­ keit bereit, zwischen unterschiedlichen Geräuschen zu wählen. So kann von klassischer Musik bis hin zu Moto­ rengeräusche von großvolumigen Fahrzeugen oder dem Fahrgeräusch einer Dampflokomotive ein großes Spektrum von Klängen und Geräuschen abgedeckt werden.In order to meet the well-being-enhancing sonic taste of a large number of potential users, the noise generator 12 provides the option of choosing between different noises. From classical music to engine noises from large-volume vehicles or the driving noise of a steam locomotive, a wide range of sounds and noises can be covered.

Derartige Geräuschimitationen können auch in Luft- und Wasserfahrzeuge eingebaut sein. So können z. B. manipu­ lierte und veränderte Motorgeräusche und Vibrationen der unterschiedlichsten Frequenzen oder Frequenzberei­ che bei Motor- oder Segelbooten imitiert werden. Sollen bei nicht mittels einer Drehkraftmaschine angetriebenen Fahrzeugen ein Fahrgeräusch imitiert werden, so ist die Verwendung von mit Fremdenergie betriebene, fahrzeu­ gunabhängigen Geräuschgeneratoren vorgesehen. Such imitations of noise can also be found in air and Watercraft can be installed. So z. B. manipu engine noise and vibrations of different frequencies or frequency range be imitated in motor or sailing boats. Should for those not driven by a rotary engine A driving noise are imitated in vehicles, so that is Use of vehicles powered by external energy gun-dependent noise generators provided.
