Abstract

The invention relates to a method for outputting audio signals of at least one audio display device (2) arranged in a vehicle (1). According to the invention, the output of the audio signals in the case of detected, verbal acoustic signals is automatically delayed by a period of the presence of the verbal acoustic signals or the audio signals are output automatically seat-oriented.

Description

The invention relates to a method for outputting audio signals of at least one audio playback device arranged in a vehicle.

From the DE 198 27 197 A1 For example, a method and apparatus for influencing the volume of audio playback devices in motor vehicles is known. The method provides that, depending on the perception of verbal acoustic signals from vehicle occupants, the volume of the audio playback devices is reduced and remains reduced as long as the verbal acoustic signals are present within any time window.

The invention has for its object to provide a comparison with the prior art improved method for outputting audio signals in a vehicle.

The object is achieved by the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A method for outputting audio signals of at least one audio reproduction device arranged in a vehicle provides according to the invention that the output of the audio signals with detected, verbal acoustic signals, in particular of occupants of the vehicle, is delayed by a period of presence of the verbal acoustic signals or if the Audio signals are output automatically seat-oriented.

By automatically outputting the audio signals either time delayed or seat oriented in the presence of verbal acoustic signals, operation of the audio playback device to turn it off, for example, or to adjust a volume, is not required. Since the operation is not required, a driver of the vehicle is not substantially distracted from a driving event, whereby the safety during driving of the vehicle is substantially increased.

For example, the verbal acoustic signals is a telephone call, wherein the driver is not distracted by the operation of the audio playback device in addition to telephoning. Furthermore, the verbal acoustic signals may be a conversation between occupants of the vehicle. The output of the audio signals is preferably seat-oriented, so that a loudspeaker for outputting the audio signals in the area of an occupant conducting the conversation or in the area of several inmates leading to a conversation is automatically switched off or the audio signals are output at reduced volume.

In addition to increasing security, comfort in making calls, especially telephone calls, is increased.

Embodiments of the invention will be explained in more detail below with reference to a drawing.

It shows:

1 schematically a vehicle with an audio player and connected to this speaker.

In the only figure is a vehicle 1 with an audio player 2 for the output of audio signals in the vehicle 1 shown.

To output the audio signals in the vehicle 1 is the audio player 2 to a driver's speaker L1, to a passenger's speaker L2, to a rear speaker L3 and to another rear speaker L4.

The driver's loudspeaker L1 is in the area of a driver's seat 3 , the passenger speaker L2 in the area of a passenger seat 4 , a rear speaker L3 in the area of a rear seat 5 and the other rear speaker L4 in the area of another rear seat 6 arranged.

It is often the case that conversations conducted by inmates or a telephone call conducted by an occupant are interrupted or disturbed by the output of audio signals, for example by announcements from a navigation system and / or by music.

In particular, in such a case, an operation of the audio playback device 2 to reduce the volume of the output audio signals or to turn off the audio playback device 2 thus avoiding the risk of distracting a driver of the vehicle 1 is at least reduced by the driving, is to output the audio signals in the vehicle 1 provided that verbal acoustic signals from occupants of the vehicle 1 be recorded.

For this purpose, preferably at least one microphone 7 , preferably in the roof area of the vehicle 1 arranged directional microphone, in the vehicle 1 provided, which while driving the vehicle 1 continuously detects signals. The by means of the microphone 7 detected signals are for evaluation fed to an evaluation unit, not shown, with the microphone 7 and the audio player 2 connected is.

In other embodiments, a plurality of such microphones 7 be provided, for example, each vehicle seat area is a microphone 7 assigned. The microphone 7 or the microphones 7 may or may, for example, a part of a telephone handsfree and / or voice control unit of the vehicle 1 be. By the advantageous use of such existing microphones 7 for the method described below advantageously eliminates the installation of additional microphones 7 ,

The evaluation unit is designed such that between noises of vehicle systems, audio signals of the audio playback device 2 and talking to inmates, and approximately locating a source of noise.

In addition, it is advantageously provided that based on the detected signals of the microphone and / or by means of a vehicle 1 integrated phone interface is determined, whether in the vehicle 1 a telephone call is made. The carrying of a telephone call becomes particularly with existing telephone integration in the vehicle 1 detected.

It is determined that in the vehicle 1 is spoken, for which purpose verbale acoustic signals are detected by at least one occupant, so provides an alternative that the output of audio signals is interrupted and automatically delayed by a period of presence of the verbal acoustic signals. That is, for the duration of the call, an output of audio signals of the audio playback device 2 is deactivated by means of the loudspeakers L1 to L4 and after no verbal acoustic signals are detected by occupants, the output of the audio signals is activated. In this case, the output of the audio signals from the time of the interruption takes place, ie delayed, so that occupants of the vehicle 1 have missed anything in terms of the output of the audio signals.

Additionally or alternatively, it may be provided that, in the case of comparatively important audio signals, in particular in the case of an announcement by the navigation system, an indication is displayed on a display unit in the vehicle 1 is highlighted visually and / or lights up in a predetermined frequency. This is done in particular when the output of these important audio signals is delayed in a deactivated manner and / or in the manner described above and / or when a volume of the output is reduced.

As an alternative to the time-delayed output of the audio signals, it is provided that upon detection and localization of the verbal acoustic signals of occupants, the loudspeakers L1 to L4 of the vehicle seats 3 . 4 and seats 5 . 6 be driven to output the audio signals in the area where no verbal acoustic signals have been located. This is useful, in particular, for making a telephone call, since the telephone occupant is not disturbed by the audio signals, but the other occupants continue to receive the audio signals, which minimizes the telephone-related impairment of the other occupants. Furthermore, this makes sense for entertaining, in which not all occupants participate, because in this way the entertaining inmates are not disturbed by the audio signals and the entertainment-related impairment of the other inmates is minimized.

In a further possible embodiment, upon detection of verbal acoustic signals of at least one occupant, the volume of the vehicle 1 Reduced output audio signals in order not to interfere with the conversation.

By locating at least one speaking occupant as a sound source, z. As in a telephone occupant, only the volume of the occupant associated speaker L1 to L4 reduced.

It is detected in the vehicle 1 When a conversation is taking place, the volume of the speakers L1 to L4 associated with occupants who are classified as listeners and not as speakers can be reduced.

For the occupants, especially the driver and the passenger, of the vehicle 1 It is possible at any time to adjust the volume manually and / or the automatically presettable settings regarding the output of the audio signals in the vehicle 1 to disable.
