Definitions
- the invention relates to a method and a device for operating an audio system in a motor vehicle, in which traffic radio broadcasts are recognized by the receipt of a specific identifier, and are switched from the current audio playback to traffic radio and / or switched manually and switched back again at the end of the traffic announcement is, during the time of the traffic announcement a level increase in volume is effected, according to the preamble of claims 1 and 9.
- Traffic radio station is, to said traffic radio station on the currently one
- Traffic announcement automatically returns the device to the original transmitter or to the original music carrier playback by means of a second identifier.
- Traffic announcements are sent, which are repeated continuously on an endless belt and updated if necessary. Since these frequencies are fixed, a station key of the audio system is often assigned the corresponding frequency.
- Control element with it. This has the advantage that the user does not have to switch to the AM area in order to be able to press the corresponding AM station button. It is usual for the volume of the volume to be raised automatically for the traffic announcement. This is to ensure that the traffic announcement can be clearly and unambiguously understood without having to adjust the volume accordingly. Many devices therefore have a preset volume for a traffic announcement, ie the user can either limit it or raise it as desired and also save the level.
- the traffic announcements or the traffic radio stations are linked to the locally or regionally valid stations.
- the traffic jam reports or traffic announcements should be current and limited to the catchment area that is in the reception area of the respective station.
- Signs are often attached to the edge of the motorways, indicating the relevant current traffic radio stations with the appropriate frequency.
- the driver can then select said frequency or, for example, call up the corresponding transmitter from an RDS device. This requires a corresponding setting, which must be readjusted several times when the driver leaves a transmission area and drives into the effective range of a new transmitter.
- EON mode means the operating mode in which any station can be heard, and with every current traffic announcement a switchover to the traffic information station is effected and then a return to the originally set station is achieved.
- EP 0 795 974 A 2 discloses a method and a receiver for reproducing received spoken messages, as well as a method for sending spoken messages. It is provided here that when a group of the data signal with predetermined content is received, the playback device is set to the playback of simultaneously received audio signals at a predetermined volume and or the audio signals received simultaneously get saved. As a result, important spoken messages that cannot be coded in the TMC system can be played back to the receiver at increased volume or after the playback of a recording has been switched off. A method for sending spoken messages and a receiver for receiving spoken messages are also described, which also correspond to the above-mentioned mode of operation.
- a so-called vehicle route guidance device is specified from EP 0 580 157 B1, in other words a navigation system for motor vehicles, which is provided with an automatic volume level adjustment.
- the volume level is increased in order to achieve a clear intelligibility and to stand out from other background noises.
- a corresponding level adjustment in the known manner does not take into account any differentiation here.
- the invention is therefore based on the object of improving a method and a device of the generic type in such a way that the relative level adjustments of the volume are adapted in a more differentiated manner to the previously and subsequently heard music reproduction.
- the volume level during the traffic announcement is regulated depending on the modulation of the station currently tuned before the traffic announcement or the music carrier playback previously heard.
- the file can be regulated either as a function of the average AM modulation level or as a function of the average FM hub of the station currently tuned to before the traffic announcement or the playback or both of them.
- the procedures which can either be used together or separately, are based on the knowledge that classic stations have a low FM hub and a low AM modulation and therefore appear to be quiet.
- Pop stations on the other hand, have a large FM hub and a large degree of AM modulation.
- the level adjustment should now be set or regulated depending on the average modulation of the station set before the traffic announcement and returning after the traffic announcement or the playback.
- the average AM modulation level and or the average FM hub is determined for each transmitter and then the average volume level to which a traffic announcement is raised is determined.
- the respective transmitter-specific average FM hub and or the average AM modulation level are each assigned to the stored transmitter and also stored, or are also renewed regularly. The latter happens automatically.
- the respective mean AM modulation or the mean FM hub which is typical for the corresponding station, is also called up and, accordingly, the volume level is influenced as soon as traffic announcements are activated.
- the receiver unit has an AM modulation and or an FM hub evaluation unit, the determined values of which can be stored in association with the currently selected transmitter or the currently reproduced medium, and that said unit is logically connected to the volume level control.
- volume level control is logically connected to the transmitter memory in order to ensure the aforementioned assigned storage of the level values to the transmitters.
- the invention takes into account both in terms of the method and of the device that so-called fixed offsets are only a compromise with regard to the level increase or decrease, as they are used in conventional devices.
- the invention essentially differentiates between several groups of transmitters, the distinction also being able to be carried out electronically.
- stations for example classic stations, which are generally heard quietly, differ clearly from stations, for example pop stations, which are generally heard loudly.
- the dynamics in the music genres can be recorded electronically through the AM modulation level and the FM hub, in the manner already described.
- the traffic radio can be set using a special traffic radio button, and then always detects the station with the strongest local traffic radio transmission capability. In this way, there is no need to switch back and forth manually between individual frequencies or transmitters if several areas are traversed on a longer journey.
- the figure shows a receiving unit 1 as the central unit.
- the receiving unit 1 is provided with an antenna (not shown further here), which accordingly receives radio signals, ie also those of the traffic radio station.
- Downstream of the receiving unit are the evaluation units 10 and 20, which are required for determining or evaluating the degree of AM modulation or the FM stroke.
- the representation of the individual components of the figure does not necessarily correspond to the advantageously chosen copying of the individual electronic elements, but is shown here in such a way that functional relationships and possibly also the process sequence can be recognized.
- the said values for the AM modulation level and for the FM hub 10, 20 are used to record the said values in the receiving unit 1 with respect to the currently set transmitters.
- the output of the volume level control 30 acts on the loudspeaker system 40 in the motor vehicle.
- a transmitter memory 50 is inserted, which can store the arriving or receiving receivers in the receiving unit.
- the transmitter memory 50 and the volume level control 30 there is also a further information technology connection which consists in that correspondingly stored transmitters are assigned a corresponding level increase after their characteristic reproduction or their characteristic music selection, that is to say their characteristic AM modulation values and FM stroke values is saved.
