Abstract

The vehicle signalling display is used to indicate to the vehicle driver the amount of noise generated by the vehicle engine, dependent on the acceleration. It employs a mechano-acoustic transducer (3) with an oscillating membrane (6) incorporated in the vehicle passenger space, coupled to the air intake line or the exhaust gas line for the IC engine via a pneumatic line containing a throttle (8) controlled in dependence on the engine acceleration. Pref. the throttle is controlled by an electric setting motor in response to a signal representing the depression of the vehicle accelerator pedal. USE/ADVANTAGE - Provides feedback signal to vehicle driver to give pleasant awareness of high-speed revolving engine esp. during acceleration. Keeps driver informed of engine running condition in car well insulated against internal and external noise.

Description

Die Erfindung bezieht sich auf ein Kraftfahrzeug, insbe­ sondere PKW, das nach dem Oberbegriff des Patentan­ spruches 1 mit einer zumindest für den Fahrzeuglenker wirksamen akustischen Anzeigevorrichtung ausgerüstet ist.The invention relates to a motor vehicle, in particular special car, which according to the preamble of the patent saying 1 with at least for the vehicle driver effective acoustic indicator is equipped.

Die bei modernen Kraftfahrzeugen wirksamen Maßnahmen zur inneren und äußeren Geräuschreduzierung lassen im Betrieb des Fahrzeuges, insbesondere bei instationärer Fahrweise, eine wünschenswerte akustische Rückmeldung an Brennkraft­ maschinen-Geräuschen vermissen.The measures effective in modern motor vehicles internal and external noise reduction let in operation of the vehicle, especially when driving unsteadily, a desirable acoustic feedback to the internal combustion engine missing machine noises.

Zur Erzielung einer akustischen Rückmeldung bietet sich nach dem bekannten Stand der Technik an, bei nach außen voll wirksamer Schalldämpfung diese für den Fahrzeug­ innenraum auf einem modulierten Sound-Effekt auszulegen. Weiter ist es im Stand der Technik bekannt, derartige Ge­ räusche auch künstlich zu erzeugen. To get an acoustic feedback offers itself according to the known state of the art, at the outside fully effective sound absorption these for the vehicle to design the interior on a modulated sound effect. It is also known in the prior art to use such Ge to generate noise artificially.  

Schließlich sind im Stand der Technik Anzeigevor­ richtungen mit einem mit dem Ansaug- oder Auspuff-System einer Brennkraftmaschine pneumatisch verbundenen mechanoakustischen Wandler bekannt. Von Ansaugluftströmen beaufschlagte Wandler in als Hupen dienenden Anzeigevorrichtungen sind aus den deutschen Patentschriften 255 721 und 299 536 bekannt. Eine Anzeigevorrichtung als Hupe mit einer von Abgasen der Brennkraftmaschine beaufschlagten Membrane ist aus der deutschen Patentschrift 427 215 bekannt.Finally, prior art displays directions with one with the intake or exhaust system an internal combustion engine pneumatically connected mechanoacoustic transducer known. From intake air flows applied transducers in serving as horns Indicators are from the German Patents 255 721 and 299 536 are known. A Display device as a horn with one of the exhaust gases Internal diaphragm is from the German patent 427 215 known.

Der Erfindung liegt die Aufgabe zugrunde, eine akustische Anzeigevorrichtung zu schaffen, die während einer Fahr­ zeugbeschleunigung der Abgabe fahrzeugbeschleunigungs­ abhängiger Brennkraftmaschinen-Geräusche dient.The invention has for its object an acoustic To create display device during a driving acceleration of the vehicle acceleration dependent engine noise is used.

Diese Aufgabe ist durch die im Kennzeichen des Patentanspruches 1 angegebenen Merkmale gelöst, wobei der Anspruch 2 eine vorteilhafte Weiterbildung beschreibt.This task is characterized by the Features specified claim 1 solved, the Claim 2 describes an advantageous development.

Der Vorteil der Erfindung liegt in der im Aufbau beson­ ders einfachen Anordnung der Membrane zur fahrzeug­ beschleunigungsabhängigen Ansteuerung zur Abgabe inter­ ner, brennkraftmaschinenbezogener Akustiksignale, wobei die Membrane durch einfache Abstimmung auf die Ansaug- und/oder Auspuff-Geräusche im Innenraum des Fahrzeuges ein reales Klangbild einer hochdrehenden Brennkraft­ maschine vermittelt. Für eine angenehme subjektive Wahr­ nehmung der akustischen Rückmeldung (Feedback) während einer Beschleunigung ist ein sportlicher Klang bzw. Sound bevorzugt. Zur Wahrnehmung der Brennkraftmaschinen-Ge­ räusche im Fahrzeug-Innenraum in Echtzeit wird die An­ zeigevorrichtung bevorzugt über das Fahrpedal ange­ steuert.The advantage of the invention lies in the particular structure simple arrangement of the membrane to the vehicle acceleration-dependent control for delivery inter ner, internal combustion engine-related acoustic signals, whereby the membrane by simply matching it to the suction and / or exhaust noises in the interior of the vehicle a real sound image of a high-revving internal combustion engine machine mediates. For a pleasant subjective truth taking the acoustic feedback (feedback) during acceleration is a sporty sound prefers. To perceive the internal combustion engine Ge Noise in the vehicle interior becomes real pointing device is preferably on the accelerator pedal controls.

Die Erfindung ist anhand einer in der Zeichnung schema­ tisch dargestellten Anzeigevorrichtung beschrieben. The invention is based on a schematic in the drawing described table device described.  

Eine Anzeigevorrichtung 1 umfaßt einen mit einer Haupt­ leitung 2 eines nicht näher dargestellten Ansaug- und/oder Auspuff-Systems einer nicht gezeigten Brenn­ kraftmaschine pneumatisch verbundenen mechanoakustischen Wandler 3. Dieser Wandler 3 ist eine in einem Fahrgast­ raum 4 am freien Ende eines mit der Hauptleitung 2 des jeweiligen Systems verbundenen Rohres 5 angeordnete Mem­ brane 6. In dem Rohr 5 ist stromauf der Membrane 6 ein vorzugsweise als Drosselklappe 7 ausgebildetes Drossel­ organ 8 angeordnet. Ein elektrischer Stellmotor 9 dient zum Antrieb der Drosselklappe 7 bzw. des Drosselorgans 8, das fahrzeugbeschleunigungsabhängig in eine der jeweili­ gen Fahrzeugbeschleunigung entsprechende Offenstellung gesteuert wird zur pneumatischen Beaufschlagung der Mem­ brane 6. Die Signale zur entsprechenden Offenstellung des Drosselorgans 8 sind vorzugsweise von Fahrpedalbewegungen abgeleitet und werden über ein Steuergerät 10 dem Stell­ motor 9 zugeführt.A display device 1 comprises a main line 2 of a not shown intake and / or exhaust system of an internal combustion engine, not shown, pneumatically connected mechanoacoustic transducer 3rd This converter 3 is arranged in a passenger compartment 4 at the free end of a tube 5 connected to the main line 2 of the respective system Mem 6 . In the tube 5 upstream of the membrane 6, a throttle organ 8 , preferably designed as a throttle valve 7 , is arranged. An electric servomotor 9 is used to drive the throttle valve 7 or the throttle member 8 , which is controlled depending on the vehicle acceleration in an open position corresponding to the respective vehicle acceleration for pneumatic actuation of the membrane 6 . The signals for the corresponding open position of the throttle element 8 are preferably derived from accelerator pedal movements and are supplied to the actuating motor 9 via a control unit 10 .

Bei entsprechender Abstimmung der Anzeigevorrichtung 1 werden die bei einer Fahrzeugbeschleunigung auftretenden Geräusche des Ansaug- und/oder Auspuff-Systems mit einem sportlichen Klang unterlegt im Fahrgastraum 4 wiedergege­ ben und dienen zumindest dem Fahrzeuglenker als akusti­ sches Feedback.With a corresponding adjustment of the display device 1 , the noises of the intake and / or exhaust system which occur when the vehicle is accelerated are highlighted with a sporty sound in the passenger compartment 4 and serve at least the vehicle driver as acoustic feedback.
