Abstract

The method involves reducing the loudness when reversing motion is detected. Reversing is detected when reverse gear is selected. The loudness is reduced to zero, to a value greater than zero, or to a value set by the user.

Description

Die Erfindung betrifft ein Verfahren zur Einstellung der Lautstärke einer Audio- und/oder Videoanlage in einem Kraftfahrzeug abhängig von erkannten Fahrsituationen nach dem Oberbegriff von Patentanspruch 1.The invention relates to a method for adjusting the Volume of an audio and / or video system in one Motor vehicle depending on recognized driving situations after the Preamble of claim 1.

Es ist bereits ein derartiges Verfahren bekannt (US-PS 5,483,692), bei dem die Lautstärke einer Audioanlage abhängig von der momentanen Fahrzeuggeschwindigkeit eingestellt werden soll, um Fahrgeräusche zu übertönen.Such a method is already known (US-PS 5,483,692), in which the volume of an audio system depends can be set from the current vehicle speed supposed to drown out driving noises.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Lautstärkeneinstellung weiter zu verbessern.The present invention is based on the object Volume setting further improve.

Dies wird erfindungsgemäß gelöst durch ein Verfahren nach Anspruch 1, nach dem eine Reduzierung der Lautstärke erfolgt bei einer erkannten Rückwärtsfahrt.According to the invention, this is solved by a method according to Claim 1, after which the volume is reduced when a reverse drive is detected.

Dabei erweist es sich als vorteilhaft, daß eine geeignete Einstellung der Lautstärke gegeben ist in einer Fahrsituation, die üblicherweise eine erhöhte Konzentration erfordert. Erfindungsgemäß wird es dem Fahrzeugführer durch die Reduzierung der Lautstärke erleichtert, sich auf die Situation zu konzentrieren. Bei einer Rückwärtsfahrt handelt es sich üblicherweise um einen Rangier- oder Parkvorgang.It proves advantageous that a suitable Setting the volume is given in a driving situation, which usually requires increased concentration. According to the invention, it is the vehicle driver by the Reducing the volume makes it easier to relate to the situation to concentrate. It is a reverse drive usually a shunting or parking process.

Bei dem Verfahren nach Anspruch 2 wird eine Rückwärtsfahrt erkannt bei einem Einlegen des Rückwärtsganges. In the method according to claim 2, a reverse drive recognized when reverse gear is engaged.  

Vorteilhaft wird dabei bereits frühzeitig die Reduzierung der Lautstärke vorgenommen, so daß der Fahrzeugführer sich leichter auf die Situation schon zur Orientierung konzentrieren kann, bevor das Fahrzeug rückwärts in Bewegung gesetzt wird.It is advantageous to reduce the early Volume made so that the driver is easier can focus on the situation for orientation, before moving the vehicle backwards.

Alternativ kann die Reduzierung der Lautstärke auch vorgenommen werden, wenn sich das Fahrzeug rückwärts in Bewegung setzt.Alternatively, the volume can also be reduced when the vehicle starts moving backwards.

Bei dem Verfahren nach Anspruch 3 wird die Lautstärke auf 0 reduziert.In the method according to claim 3, the volume is set to 0 reduced.

Dadurch wird in vorteilhafter Weise sichergestellt, daß der Fahrzeugführer sich auf die Verkehrssituation konzentrieren kann. Vorteilhaft ist weiterhin, wenn nicht einfach nur eine Reduzierung der Lautstärke erfolgt sondern wenn das entsprechende Gerät bzw. die entsprechenden Geräte ausgeschaltet wird. Gegebenenfalls kann dieses Ausschalten gleichzeitig erfolgen, wenn der Motor ausgeschaltet wird. Dabei kann beispielsweise vorgesehen sein, daß die Ausschaltung nur dann erfolgt, wenn der Motor in einem zeitlichen Zusammenhang mit der erkannten Rückwärtsfahrt abgeschaltet wird.This ensures in an advantageous manner that the Drivers concentrate on the traffic situation can. It is also advantageous if not just one The volume is reduced but if that corresponding device or devices is turned off. If necessary, this can be switched off done simultaneously when the engine is turned off. Here can be provided, for example, that the switch-off only then occurs when the engine is in a temporal context is switched off when the reverse drive is detected.

Bei dem Verfahren nach Anspruch 4 wird die Lautstärke auf ein vorgegebenes Level größer als 0 gesetzt.In the method according to claim 4, the volume is on specified level is set greater than 0.

Damit kann erreicht werden, daß ein Level der Lautstärke einstellbar ist, bei dem eine Konzentration auf die Verkehrssituation sicher möglich ist.It can be achieved that a level of volume is adjustable, in which a concentration on the Traffic situation is safely possible.

Bei dem Verfahren nach Anspruch 5 erfolgt eine Reduzierung abhängig von der vom Benutzer eingestellten Lautstärke.In the method according to claim 5 there is a reduction depending on the volume set by the user.

Damit kann vorteilhaft erreicht werden, daß das Level der Lautstärke bei einer erkannten Rückwärtsfahrt den Hörgewohnheiten des Benutzers angepaßt wird.This can advantageously be achieved that the level of Volume when a reverse drive is detected Listening habits of the user is adjusted.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung näher dargestellt. Die Figur zeigt dabei ein Autoradio 1, das an seiner Rückseite einen Anschluß 2 aufweist. Dieser Anschluß 2 kann beispielsweise der Anschluß der Stummschaltung durch das Autotelefon sein. Indem dieser Anschluß mit Masse verbunden wird, erfolgt die Stummschaltung des Autoradios.An embodiment of the invention is shown in more detail in the drawing. The figure shows a car radio 1 which has a connector 2 on its rear. This connection 2 can be, for example, the connection of the muting by the car phone. By connecting this connection to ground, the car radio is muted.

Im Zusammenhang mit der vorliegenden Erfindung ist dazu ein Relais 3 vorgesehen, dessen Steueranschluß über einen Anschluß 4 mit dem Rückfahrlichtschalter des Getriebes verbunden sein kann, der mit +-Potential verbunden wird, wenn der Rückwärtsgang eingelegt wird. In diesem Fall zieht das Relais 3 an, so daß der Kontakt 6 geschlossen wird.In connection with the present invention, a relay 3 is provided, the control connection of which can be connected via a connection 4 to the reversing light switch of the transmission, which is connected to + potential when the reverse gear is engaged. In this case, the relay 3 picks up, so that the contact 6 is closed.

Bei Erreichen des statischen Zustands legt der Widerstand 5 die Lautstärke bei Rückwärtsfahrt fest. Diese Lautstärke kann beispielsweise mit "0" festgelegt werden, mit einem bestimmten, konstant vorgegebenen Level oder mit einem Level, das abhängig ist von der Lautstärkeneinstellung, die vom Benutzer vorgegeben wird.When the static state is reached, the resistor 5 determines the volume when reversing. This volume can be set, for example, with "0", with a specific, constantly predetermined level or with a level which is dependent on the volume setting which is specified by the user.

Die Dimensionierung des Kondensators 7 bestimmt die Dauer des Einschwingvorganges, mit der die Lautstärke des Autoradios reduziert wird.The dimensioning of the capacitor 7 determines the duration of the transient process with which the volume of the car radio is reduced.

Anstelle des dargestellten Beispiels unter Verwendung der Stummschaltung des Autoradios durch das Autotelefon kann beispielsweise auch der Eingang zur fahrgeschwindigkeitsabhängigen Regelung der Lautstärke des Autotelefons verwendet werden.Instead of the example shown using the The car radio can be muted by the car phone for example, the entrance to speed-dependent control of the volume of the Car phones are used.
