Definitions

  • the present invention relates to a radio receiver for a vehicle, in particular a radio receiver for the reception of additional signals provided radio signals in problematic for radio reception Areas.
  • Radio Data Standard RDS
  • broadcast signals with corresponding additional signals are received, in particular occur Areas such as underpasses, tunnels or garages have problems.
  • tunnels or garages can occur annoying noise during the interruption and partly to the loss of the originally set and before the interruption of the broadcast signal received station.
  • the invention is based on the consideration that by saving the additional information characterizing the transmitter, or the Reception frequency of the transmitter, this also after an interruption, such as. B. caused by shadowing of the radio signals, reset and can be received.
  • the advantage of the radio receiver according to the invention is in particular in that disruptive channel changes are avoided.
  • the figure shows a basic circuit diagram of an embodiment of a Radio receiver according to the invention with an antenna 1, one Receiving device 2, an audio amplifier 3, one or more Speakers or groups of speakers 4, a display 5 and one Control device 6, which is formed, for example, by a microcomputer can be.
  • a connection 7 for a switched Supply voltage provided, for example by means of the ignition lock of the vehicle in which the radio receiver is installed can.
  • Radio signals from the antenna 1 received in the receiving device 2 by means of not shown High frequency, intermediate frequency and demodulator circuits Broadcast signal selected under control of the control device 6.
  • the Audio signal of the received broadcast signal is sent to the audio amplifier 3 passed on, controlled by the control device 6, for playback amplified by the speaker (s) 4.
  • the receiving device 2 provides the Control device 6 also contained in the broadcast signal Additional information, e.g. B. according to the RDS standard.
  • the Additional information can be shown on the display 5, for example.
  • the receiving device 2 of the control device 6 can provide information available via the reception field strength of the respective received transmitter put.
  • the radio receiver constructed as described above, the for example installed in a vehicle, operated in an area in which the radio reception is shadowed, such. B. in an underpass, a tunnel or a garage, the Receiving the set station.
  • the interruption is also due to the reduced reception level caused by the radio receiver an alternative can be initiated by controlling the control device 6 Frequency of the originally tuned station. Because of the Shadowing of the radio signals no station can be received, this remains Attempt unsuccessful. A station search also remains because of the shadowing of the Broadcast signals unsuccessful. Therefore disturbing noise is reproduced. If you leave the shading area, the originally set transmitter is lost. A new search is carried out and a station becomes random set and played.
  • the Control device 6 detects a reduction in the reception field strength from which Control device 6 the available over the currently set transmitter Information such as transmitter frequency and / or the transmitter Additional information, e.g. B. PS and / or PI code, stored. At the same time controls the control device 6 to the audio amplifier 3 in order to amplify the to terminate the signal delivered by the receiving device 2, d. H. on So-called NF mute is effected by the control unit 6. This will not play annoying noise.
  • transmitter Information such as transmitter frequency and / or the transmitter Additional information, e.g. B. PS and / or PI code
  • the control device 6 After completion of the shadowing of the broadcast signals, i. H. if from the Control device 6 re-evaluable reception levels are determined, the control device 6 checks whether the one set before the interruption Transmitter can still be received. For this, the saved Reception frequency from the control device 6 at the reception device 2 set. If no level is found or indicates sufficient for reception the station now received is different from the stored one Additional information (PI and / or PS code), a station search carried out. The receivable stations are stored on the Additional information of the originally set station, such as PS and / or PI code, checked. Based on this review, the original tuned and received stations tuned again after the interruption and reproduced, even if it is now on a different frequency Will be received.
  • the additional information PI and / or PS code
  • a similarly marked transmitter is preferably set and reproduced.
  • the control device 6 controls the Audio amplifier 2 on and restores the originally set volume on.
  • transmitter-related information is again shown on the display 5 shown, such as. B. reception frequency and / or station name.
