Abstract

The signal tone device provides a continuous or intermittent warning signal tone during the forwards movement of the vehicle which is softer than the sound provided by the vehicle horn. The signal tone source may be incorporated in the lamp housings of the front headlamps and/or trafficator lamps, with further signal tone sources for radiating a signal tone to the sides and rear of the vehicle.

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1The invention relates to a device according to the preamble of claim 1

Aus der DE 30 12 776 A1 und der DE 32 25 407 A1 sind ähnliche Vorrichtungen be­ kannt, die bei eingelegtem Rückwärtsgang einen Signalton von der Rückseite des Fahrzeuges aus abgeben. Derartige Vorrichtungen sind manchmal in Fahrzeugen ein­ gebaut, bei denen der Fahrzeugführer bei Rückwärtsfahrt in den hinter dem Fahrzeug liegenden Bereich keine Einsicht hat, wie z. B. bei Sattelzügen, Gliederzügen oder Ge­ lenkomnibussen. Bei diesen Fahrzeugen ist es in jedem Fall erforderlich, daß ein Ein­ weiser die Rückwärtsfahrt freigibt und dieser vom Fahrer über einen der Rückspiegel beobachtet werden muß.Similar devices are known from DE 30 12 776 A1 and DE 32 25 407 A1 knows the one beep from the back of the when reverse gear is engaged Drop off the vehicle. Such devices are sometimes used in vehicles built in which the driver when reversing into the rear of the vehicle lying area has no insight, such as B. in semi-trailers, articulated trains or Ge steering buses. In these vehicles, it is necessary that an on wise the backward drive and this by the driver via one of the rear-view mirrors must be observed.

Der Erfindung liegt die Aufgabe zugrunde, bei lärmarmen Kraftfahrzeugen im unteren Geschwindigkeitsbereich bei Vorwärtsfahrt Passanten, wie Fußgänger und Radfahrer, zu warnen, ohne die sehr laute Hupe zu betätigen.The invention has for its object in low noise vehicles in the lower Speed range when driving forward passers-by, such as pedestrians and cyclists, to warn without pressing the very loud horn.

Die Aufgabe wird erfindungsgemäß durch die Merkmale dem Anspruches 1 gelöst.The object is achieved by the features of claim 1.

Mit lärmarmen Kraftfahrzeugen sind jene Kraftfahrzeuge gemeint, die bestimmte Ge­ räuschgrenzwerte, z. B. die nach § 49, 3, Anlage XXI StVZO nicht überschreiten. Wei­ terhin ist die Anwendung des Gegenstandes der Erfindung auch in Kraftfahrzeugen mit elektromotorischem Antrieb sinnvoll.Low-noise motor vehicles mean those motor vehicles that have certain Ge noise limits, e.g. B. do not exceed the according to § 49, 3, Annex XXI StVZO. Wei furthermore, the application of the subject of the invention is also in motor vehicles electric motor drive makes sense.

Lärmarme Nutzfahrzeuge dürfen in verkehrsberuhtigten Zonen und häufig sogar in Fußgängerzonen fahren. Da diese Fahrzeuge dabei im Teillastbereich fahren, wobei deren Antriebsmotoren dann im unteren und mittleren Drehzahlbereich arbeiten und das Rollgeräusch der Fahrzeuge noch nicht am Gesamtgeräusch beteiligt ist, hebt sich das Gesamtgeräusch eines dieser Fahrzeuge nicht mehr oder nur unwesentlich vom Umgebungsgeräusch ab. Das Umgebungsgeräusch in z. B. Fußgängerzonen wird er­ zeugt von Gesprächen der Menschen miteinander, vom Geräusch aufsetzender Schu­ he auf den Bodenbelag, von einem Geigenspieler oder mehreren Musikanten und von Turmglocken, die die Uhrzeit schlagen.Low-noise commercial vehicles are allowed in restricted traffic areas and often even in Drive pedestrian zones. Since these vehicles drive in the partial load range, whereby whose drive motors then work in the lower and middle speed range and the rolling noise of the vehicles is not yet part of the overall noise increases the total noise of one of these vehicles no longer or only insignificantly from  Ambient noise. The ambient noise in e.g. B. It becomes pedestrian zones testifies to the conversations of people with each other, the sound of footwear hey on the flooring, by a violin player or several musicians and by Tower bells that beat the time.

Im Nahfeld eines Passanten sind bei besonders dichtem Fußgängerverkehr die Geräu­ sche meistens noch höher, als das Umgebungsgeräusch, da der Passant von Geräu­ schen, wie z. B. Gesprächsteilen oder rauschender Kleidung seiner ihm am nähesten befindlichen Mitfußgänger beaufschlagt wird. Auch kann das Geräusch eines lärmar­ men Fahrzeuges durch alle möglichen Gegenstände, z. B. durch große Blumentöpfe oder geparkte Fahrzeuge, "akustisch verdeckt" werden. Der Passant ist abgelenkt und rechnet nicht mit der Möglichkeit, daß ein lärmarmes Nutzfahrzeug, das er in der ge­ nannten Betriebsweise meistens nicht hören kann, sich ebenfalls in seinem Nahbereich bewegt. Der Passant kann, wenn er das Fahrzeug nicht wahrnimmt, schnell und unbe­ rechenbar in die Gefahrenzone des Fahrzeuges kommen. Die Gefahrenzone des Kraft­ fahrzeuges ist nicht nur im vorderen Bereich des Kraftfahrzeuges zu sehen, sondern auch in den seitlichen Bereichen. Der Fahrzeugführer ist in diesem Fall überlastet und kann möglicherweise einen Unfall nicht mehr vermeiden, besonders wenn es sich um ein Nutzfahrzeug handelt. Betätigt der Fahrzeugführer die Hupe, so ist der Ton so viel­ mal höher als das Umgebungsgeräusch, daß anfällige Menschen z. B. eine Herz­ attacke erleiden können. Auch Anwohner würden sich von dem Hupton belästigt fühlen.In the near field of a passer-by, the noise is particularly high when pedestrian traffic is high usually higher than the ambient noise, because the passerby of noise like, e.g. B. parts of conversation or rushing clothes its closest to him pedestrians located. Also the noise of a noise can be men vehicle through all possible objects, such. B. by large flower pots or parked vehicles that are "acoustically covered". The passer is distracted and does not count on the possibility that a low-noise commercial vehicle that he is in the ge called mode of operation mostly can not hear, also in its close range emotional. The passer-by can quickly and easily, if he does not notice the vehicle come into the danger zone of the vehicle. The danger zone of the force vehicle can be seen not only in the front area of the motor vehicle, but also in the side areas. In this case, the driver is overloaded and can possibly no longer avoid an accident, especially if it is is a commercial vehicle. If the driver operates the horn, the sound is so much times higher than the ambient noise that susceptible people z. B. a heart can suffer attack. Local residents would also feel bothered by the Hupton.

Ein erfindungsgemäß zeitlich dauerhafter oder intermittierender Signalton, der wesent­ lich leiser ist als der Hupton, aber dennoch über dem Umgebungsgeräusch liegt, macht auf das fahrende Fahrzeug aufmerksam und beseitigt damit die Gefahr von Unfällen, die aus den beschriebenen Situationen entstehen können.A signal tone that is permanent or intermittent according to the invention, the essential is quieter than the horn, but still lies above the ambient noise attention to the moving vehicle and thus eliminates the risk of accidents, that can arise from the described situations.

In vorteilhafter Ausgestaltung der Erfindung wird der Signalton in Fahrtrichtung nach vorne abgestrahlt. Die Signaltongeber sind dabei vorzugsweise in entsprechend aus­ gebildeten Leuchtengehäusen der vorderen Scheinwerfer oder in entsprechend aus­ gebildeten Blinkergehäusen integriert. In an advantageous embodiment of the invention, the signal tone changes in the direction of travel radiated in front. The beepers are preferably in accordingly formed lamp housing of the front headlights or in accordingly formed turn signal housing integrated.  

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Signaltöne auch an den Seiten des Fahrzeuges abstrahlbar. Dies hat den Vorteil, daß der Einzel­ schallpegel der Signaltongeber bei gleicher Wirkung niedriger sein kann, als bei nur nach vorne gerichtetem Signalton. Für Passanten und Anwohner ist diese Ausgestal­ tung angenehmer.According to a further advantageous embodiment of the invention, the signal tones are can also be blasted on the sides of the vehicle. This has the advantage that the individual sound level of the signal generator can be lower than with just the same effect forward beep. This is designed for passers-by and residents tion more pleasant.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Signaltonge­ ber auch in den rückseitigen Leuchtengehäusen integrierbar. Damit ist das Fahrzeug rundum akustisch wahrnehmbar. Die Einzelschallpegel der Signaltongeber können da­ durch weiter reduziert werden, so daß Passanten und Anwohner diese Ausgestaltung noch weniger stört.According to a further advantageous embodiment of the invention, the signal tone Can also be integrated in the rear light housings. So that is the vehicle audible all around. The individual sound levels of the sounder can be there by further reducing, so that passers-by and residents of this configuration even less disturbing.

Der Signalton ist dauerhaft oder intermittierend und nur bei Vorwärtsfahrt im Ge­ schwindigkeitsbereich von 1 km/h bis 40 km/h abgebbar. Bleibt das Fahrzeug stehen, schaltet auch der Signalton ab. Den Bedarf für den Signalton gibt der Fahrer mittels eines Betätigungselementes, das am Armaturenbrett oder am Lenkstock angebracht ist.The signal tone is permanent or intermittent and only when driving forward in the Ge Speed range from 1 km / h to 40 km / h can be given. If the vehicle stops, the signal tone also switches off. The driver indicates the need for the signal tone an actuator that is attached to the dashboard or the steering column is.
