Abstract

Invention relates to an emergency calling system for a passenger transporting system, especially for a motor vehicle, with a transmitter for establishing a telephonic connection with an external receiving station, such as a call center (18) or the like, as well as to a method for automatically transmitting an emergency call from a passenger transporting system, especially from a motor vehicle. At least one reproduction parameter of the audio output is set to a predefined value when the telephonic connection is established. The invention furthermore relates to an audio reproducing device for a passenger transporting system, especially for a motor vehicle.

Claims

1. Emergency calling system for a passenger transporting system, especially for a motor vehicle, which includes at least one transmitter for establishing a telephone connection with an external receiving station, such as a call center (18) or the like, at least one audio source and at least one speaker (24), characterized in that at least one reproduction parameter of the audio output is set to a predefined value after the telephone connection is established.

2. The emergency calling system of claim 1, characterized in that the emergency calling system includes a mobile telephone facility and a radio or radio navigation system (20).

3. Amended) The emergency calling system of claim 1, characterized in that the telephonic connection can be established in that an emergency calling key (12) or the like is activated by a person or by a sensor, which ascertains a critical situation or an accident, which has already taken place.

4. The emergency calling system of claim 1, characterized in that the loudness of the audio output is set to a minimum value after the telephonic connection has been established.

5. The emergency calling system of claim 4, characterized in that the loudness of the audio output can be increased, but not decreased manually with respect to the set minimum value.

6. The emergency calling system of claim 4, characterized in that it has means for calculating the minimum value, which is to be set as a function of the noise level.

7. The emergency calling system of claim 1, characterized in that the balance of the audio output is centered after the telephonic connection is established.

8. The emergency calling system of claim 1, characterized in that the fade control is set to the front after the telephonic connection has been established.

16. Audio reproduction device for a passenger transporting system, especially for a motor vehicle, characterized by an emergency calling system of claim 1.

9. Method for automatically transmitting an emergency call from a passenger transporting system, especially from a motor vehicle, characterized in that at least one reproduction parameter of the audio output is set to a predefined value when the telephonic connection is established.

10. The method of claim 9, characterized in that the telephonic connection is established when an emergency calling key (12) or the like is activated by a person or by a sensor, who or which has ascertained a critical situation or an accident, which has already taken place.

11. The method of claim 9, characterized in that the loudness of the audio output is set to a minimum value.

12. The method of claim 11, characterized in that the loudness of the audio output can be increased but not decreased manually with respect to the minimum value set.

13. The method of claim 11, characterized in that the minimum value, which is to be set, is determined as a function of the noise level.

14. The method of claim 9, characterized in that the balance of the audio output is centered.

15. The method of claims 9, characterized and that the fade controller is set to the front.
