Definitions

  • the invention relates to a method and a device for operating a Audioeinstrom in a motor vehicle, in which traffic broadcasts per Receiving a specific identifier can be detected, and from the current one Audio playback on traffic information automatically switched and / or manually is switched and is switched back at the end of the traffic announcement, wherein during the time of the traffic announcement a level increase of the volume is effected, according to the preamble of claims 1 and 8.
  • the General mode of the car audio systems is such that even at the current Listening to a non-radio station, or listening to music media such as cassette or CD same upon receipt of a station ID for a traffic announcement to be interrupted.
  • radio mode this means that the radio is receiving such an identifier immediately switches from the currently owned station, if this no Traffic news station is, to the said traffic radio station on the current one Announcement follows.
  • the device In the event that the currently set station or the current Sender was not the traffic information station, returns after the end of the Traffic announcement by a second identifier, the device automatically back to the the original station or to the original music carrier playback.
  • EON operation means one Mode in which any transmitter can be heard and at each current traffic announcement causes a switch to the traffic information station and then back to the originally tuned station is reached.
  • EP 0 795 974 A 2 discloses a method and a receiver for reproducing received spoken messages, as well as a method for transmitting spoken messages. It is provided that when receiving a group of the data signal with predetermined content, the playback device is set to the playback of simultaneously received audio signals with a predetermined volume and or simultaneously received audio signals are stored. As a result, important spoken messages which can not be encoded in the TMC system can be reproduced at the receiver at an increased volume or after the playback of a recording has been switched off. It also describes a method for transmitting spoken messages and a receiver for receiving voice messages, which also correspond to the above-mentioned mode of operation.
  • EP 0 580 157 B1 discloses a so-called vehicle-track guidance device, in other words a navigation system for motor vehicles, which is provided with an automatic volume level adjustment.
  • the volume level is raised in the passage of a Wegziel enclosuresinformation to achieve a clear understanding and stand out from other background noise.
  • a method according to the preamble of claim 1 is also known. All methods and devices have in common that the volume level increase is undifferentiated and thus can automatically assume a level that may be acoustically unpleasant for the driver concerned.
  • the invention is therefore based on the object to improve a method and a device of the generic type such that the relative level adjustments of the volume more differentiated adapted to the previously and subsequently heard music playback become.
  • the task is in a method of the generic type solved according to the invention by the characterizing features of claim 1.
  • Core of the inventive method is that the volume level during the traffic announcement depending on the modulation of the before Traffic announcement currently tuned station or the previously heard Music carrier playback is regulated.
  • the mean AM modulation degree and or the average FM hub is determined for each transmitter and then the average volume level on the at a traffic announcement is determined is determined.
  • the respective transmitter-specific mean FM stroke and or the average AM modulation level respectively stored stations are assigned and also stored, or also regularly renewed. The latter happens automatically.
  • the Receiving unit an AM modulation and or an FM hub rating unit whose determined values correspond to the currently set transmitter, or the currently reproduced medium assigned stored, and that the said Unit is logically connected to the volume level control. It is intended that the traffic is adjustable via a special traffic button, and then always detected the locally strongest radio station capable transmitter. In this way does not need to manually switch between individual frequencies or stations be switched when several areas go through in a long drive become.
  • volume level control logically with the Transmitter memory is interconnected to the said assigned storage of To ensure level values to the transmitters.
  • the invention carries both in accordance with the procedure as well as in setup Be aware of the fact that so-called fixed offsets in terms of leveling or lowering, as used in common facilities, only one Compromise.
  • the invention essentially distinguishes several groups of transmitters, the distinction is also electronically enforceable.
  • Sender for example Classical stations, which are usually quietly heard, differ accordingly clearly from broadcasters, for example pops, which are usually heard aloud.
  • the dynamics in the music genres are electronically detectable by the AM modulation degree and the FM hub, in the manner already described.
  • the figure shows a central unit of a receiving unit 1.
  • the receiving unit. 1 is provided with an antenna not shown here, the corresponding Broadcast signals, including the traffic station receives.
  • the receiving unit downstream are the valuation units 10 and 20, for the determination or the Assessment of the AM modulation level or the FM hub are needed.
  • the representation of the individual components of the figure does not represent all usual device elements but only shows individual electronic elements, but is shown here so that functional relationships and possibly also the Recognize procedure. So are the above valuation units for the AM modulation degree and for the FM hub 10, 20 the said values in the Receiving unit 1 detected with respect to the currently set transmitter.
  • the signals of the evaluation units 10 and 20 for the AM modulation and the FM hub of the volume level control 30 supplied.
  • the Volume level control will determine the detected AM modulation grade values and the FM stroke size implemented accordingly when the receiving unit 1 a Traffic announcement on one, on the appropriate station at short notice switched connection comes in. It thus takes a usual Volume level boosts the voice message accordingly well and unmistakably be detected by the occupants, in particular by the driver can. That is, the output of the volume level control 30 acts on the Loudspeaker system 40 in the motor vehicle.
  • a station memory 50 is inserted, which in the Receiving unit incoming, or via the same receivable transmitter can save.
  • a manual volume level engagement 60 still allows the operator to total affect the volume, as this manual intervention hierarchical is superior. Ie. the manual volume level intervention is in the device as prioritized.
