Abstract

Method and device for transfer of noises or sound, whereby external noise is replayed almost immediately within the interior of a motor vehicle or converted into a warning signal. The inventive device has sound sensors or microphones that arranged to the rear and sides of a motor vehicle.

Description

Ein Verfahren/eine Vorrichtung mit deren Hilfe der Fahrer Außergeräusch verstärkt wahrnimmt – insbesondere zur Wahrnehmung, Warnung oder Orientierung beim Rückwärtsfahren.On Method / a device with the help of which the driver perceives increased noise - in particular for perception, warning or orientation when reversing.

Beschreibung:Description:

Die Erfindung betrifft ein Verfahren/eine Vorrichtung zur Verbesserung der Wahrnehmung, Warnung und Orientierung des Fahrers insbesondere beim Rückwärtsfahren. Typischerweise orientiert sich ein Mensch auch am Gehör – insbesondere nimmt er hierdurch Warngeräusche war. Jedoch ist normalerweise das Ziel bei der Auto-Entwicklung den Fahrer möglichst gut von Außergeräuschen abzuschirmen. Dies ist insbesondere hinderlich beim Rückwärtsfahren, wobei die Sicht stark eingeschränkt sein kann. Man denke nur an Situationen wie z.B. wenn man einen Kombi hinten voll Gepäck für den Urlaub geladen hat. In anderen Situationen kommen die Fahrer schon selber auf eine Teillösung des Problems. Zum Beispiel beim Rangieren mit einem Anhänger, der sehr lang ist (wie z.B. ein Bootsanhänger), ist es hilfreich das Fahrerfenster zu öffnen, da man im Allgemeinen dann einen anderen Verkehrsteilnehmer erst hört – bevor man ihn sieht. So kann man rechtzeitig beim Rückwärtsfahren anhalten. Bei viele Kleinlasterfahrer im Lieferverkehr kann man auch beobachten, dass sie das Fahrerfenster geöffnet haben beim Rückwärtsfahren. Fährt man mit Einweiser rückwärts, so kann dieser Handzeichen geben oder muß laut rufen, damit der Fahrer in selbst bei geöffnetem Fenster noch versteht. In allen beschriebenen Fällen wäre es also hilfreich für die Wahrnehmung des Fahrers die rückwärtigen Geräusche an den Fahrer weiterzugeben. Auch Warnrufe ansonsten unbeteiligter Passanten könnten so vom Fahrer wahrgenommen werden. Dies kann bei einem normalen LKW aufgrund der starken Auspuffgeräusche problematisch sein. Auf jeden Fall bleibt festzuhalten, dass die passive Wahrnehmung vor möglichen Gefahren durch diese Erfindung verbessert wird. Bei einer Stereoübertragung wird vorzugsweise der räumliche Eindruck im Auto nachgebildet, um dem Fahrer die räumliche Orientierung zum anderen Verkahrsteilnehmer zu ermöglichen. Voraussichtlich ließen sich durch die hier beschriebene Erfindung viele klein Unfälle beim Rangieren/Rückwärtsfahren vermeiden. Ferner soll die Übertragung der Geräusche nahezu zeitgleich erfolgen – d.h. deutlich unter 10sec. Vorzugsweise ist der zeitliche Versatz zwischen Aufnahme und Wiedergabe fast nicht messbar oder hörbar – d.h. ggf. kleiner 1Femtosekunde oder 1Millisekunde.The The invention relates to a method / a device for improvement the driver's perception, warning and orientation, especially when Drive backwards. Typically, a person also orientates himself by hearing - especially taking this causes warning noises was. However, the goal is usually in auto development the driver if possible well shielded from noise. This is particularly cumbersome when reversing, with the view highly limited can be. Just think of situations such as if you have one Combined rear luggage for vacation loaded. In other situations, the drivers come themselves to a partial solution of the Problem. For example when maneuvering with a trailer, the is very long (such as a boat trailer), it helps that Open driver's window because in general you only have another road user listen - before you see him. So you can stop in time when reversing. With many Small truck drivers in delivery traffic can also be observed that they opened the driver's window have when reversing. You drive with guide backwards, see above can give this hand signal or must shout loudly so that the driver in even when open Window still understands. In all of the cases described, it would be helpful for perception the rear noises pass the driver on. Also warning calls otherwise uninvolved Passers-by could be perceived by the driver. This can be normal Trucks can be problematic due to the strong exhaust noise. On in any case it should be noted that the passive perception before possible Hazards are improved by this invention. With a stereo transmission preferably the spatial Imitation imitated in the car to give the driver the spatial To enable orientation to the other road user. Probably left by the invention described here many small accidents Maneuvering / reversing avoid. Furthermore, the transfer of Sounds occur almost simultaneously - i.e. clear under 10sec. Preferably, the time lag between recording is and playback almost not measurable or audible - i.e. possibly less than 1 femtosecond or 1 millisecond.

Die Vorrichten könnte bestehen aus einem oder mehreren Mirkophonen die vorzugsweise in der hinteren Partie des Fahrzeuges montiert sind (siehe hierzu 1). Eine mögliche Position wäre auch die der Abstandswarner in dem Stoßfänger. Vorzugsweise wird der Schall im Innenraum durch Lautsprecher erzeugt. Hierzu eignet sich besonders die meist vorhandene Stereoanlage im Fahrzeug. Die Signale der Außenmikrophone werden entweder zusätzlich als Signal über einen Verstärker auf die Lautsprecher gegeben – oder vermutlich besser über einen separaten Eingang als Tonsignal vom "Autoradio" weitergegeben, wobei noch ein Signal für den Fahrzustand des Rückwärtsfahrens mit berücksichtigt wird – bzw. eine Signal über eine niedrige Geschwindigkeit oder ähnliches.The devices could consist of one or more microphones, which are preferably mounted in the rear of the vehicle (see here 1 ). A possible position would also be that of the distance warning device in the bumper. The sound in the interior is preferably generated by loudspeakers. The mostly existing stereo system in the vehicle is particularly suitable for this. The signals from the external microphones are either sent to the loudspeakers as a signal via an amplifier - or better transmitted via a separate input as a sound signal from the "car radio", whereby a signal for the driving state of reversing is also taken into account - or a signal via a low speed or the like.

Die Vorrichtung kann somit im wesentlichen bestehen aus (siehe hierzu 4) einem oder mehreren Mirkophonen (1), einem oder mehrerer Verstärker oder Radio/Audioanlage (2) und einem oder mehrerer Lautsprechern (3). Verarbeitet werden kann noch ein Signal über den Fahrzustand (4) – bzw. das eigentliche Tonsignal kann ggf. auf dem Weg zu den Lautsprechern mittels einer Filterfunktion (5) noch verarbeitet bzw. aufbereitet werden. Über ein Bedienelement (7) kann die Möglichkeit geschaffen werden, dass das gesamt System zu konfigurieren hinsichtlich Funktionalität bzw. Lautstärke oder Deaktivierung des Systems. Die Übertragung kann – vorzugsweise bei längeren Fahrzeugen oder welchen mit Anhänger – auch per Funkstrecke (8) erfolgen.The device can thus consist essentially of (see here 4 ) one or more microphones ( 1 ), one or more amplifiers or radio / audio system ( 2 ) and one or more speakers ( 3 ). A signal about the driving status can also be processed ( 4 ) - or the actual sound signal can possibly be on the way to the speakers using a filter function ( 5 ) are still processed or processed. Via a control element ( 7 ) it is possible to configure the entire system in terms of functionality, volume or deactivation of the system. The transmission can - preferably for longer vehicles or those with a trailer - also via radio link ( 8th ) respectively.

Mittels dieser Vorrichtung wäre es dann auch denkbar spezielle Aussengeräusche zu verstärken bzw. herauszufiltern. Der Ton eines Martinshornes könnte zum Beispiel auch während der Fahrt (verstärkt) übertragen werden. Anders herum könnten Wind- oder Fahr-/Auspuffgeräusche herausgefiltert werden. Alternativ kann auch stellvertretend ein Warnsignal anstelle der Außengeräusche erzeugt werden.through this device would be then it is also conceivable to amplify special external noises or filter out. The sound of a Martinshorn could, for example, also during the Transfer drive (intensified) become. The other way around, wind or driving / exhaust noise could be filtered out. Alternatively, a warning signal can be substituted for the Outside noises are generated.

Der besondere Vorteil der Erfindung besteht also in der zu erzielenden Wirkung eines akustischen Rückspiegels der durch die Nachbildung des Schalls die passive Wahrnehmung des Fahrers von Geräuschen oder gezielten Rufen (z.B. eines Einweisers) unterstützt. Diese passive/aktive Wahrnehmung von Geräuschen durch den Fahrer kann Unfälle vermeiden, da andere Verkehrsteilnehmer "gehört" werden.The So particular advantage of the invention is that to be achieved Effect of an acoustic rearview mirror which through the reproduction of the sound the passive perception of the Driver of noise or targeted calls (e.g. a guide). This passive / active perception of noise by the driver accidents avoid because other road users are "heard".

Als Stand der Technik ist bekannt der Handy-Eingang am Autoradio und der Abstandswarner, der in die Stoßfänger integriert ist.As State of the art is the cell phone input on the car radio and the distance warning integrated in the bumpers.
