Abstract

A system for attenuating vehicle audio for mobile application audible statements, the system comprising a vehicle computing system having one or more processors for playing audio in the vehicle from a plurality of different audio sources. The system also includes a wireless transceiver for communicating signals from a mobile computing device for processing by the vehicle computing system. The vehicle computing system is configured to receive a wireless signal from the mobile computing device representative of an audible statement to be played in the vehicle. If the vehicle computing system is playing audio in the vehicle at the time the wireless signal is received from the mobile computing device, determine an amount to attenuate the audio based on the source of the audio. Attenuate the audio and play the audible statement based on the determination.

First claim

What is claimed is:

1. A system for attenuating vehicle audio for mobile application audible statements, the system comprising:
a vehicle computing system having one or more processors for playing audio in the vehicle from a plurality of different audio sources; and
a wireless transceiver for communicating signals from a mobile computing device for processing by the vehicle computing system;
wherein the vehicle computing system is configured to:
receive a wireless signal from the mobile computing device representative of an audible statement to be played in the vehicle;
if the vehicle computing system is playing audio in the vehicle at the time the wireless signal is received from the mobile computing device, determine an amount to attenuate the audio based on the source of the audio; and
attenuate the audio and play the audible statement.

2. The system of claim 1 , wherein the amount to attenuate the audio is zero.

3. The system of claim 1 , wherein the vehicle computing system is further configured to receive a caller identification from the mobile computing device identifying the mobile application.

4. The system of claim 3 , wherein the caller identification includes a calling line identification presentation.

5. The system of claim 3 , wherein the caller identification contains an alpha-numeric number that is incapable of making an operable phone-call to a phone line.

6. The system of claim 1 , wherein the wireless signal from the mobile computing device includes an AT command.

7. The system of claim 6 , wherein the AT command is a list current call command.

8. The system of claim 1 , wherein the vehicle computing system is further configured to receive an audio video remote control profile message indicating the mobile device is requesting to output an audible statement.

9. The system of claim 1 , wherein the wireless signal is received from the mobile computing device utilizing an enhanced synchronous connection-oriented link.

10. The system of claim 1 , wherein the wireless signal is received from the mobile computing device utilizing a synchronous connection-oriented link.

11. The system of claim 1 , wherein the vehicle computing system is further configured to ignore the audible statement if the source of the audio is a phone call.

12. The system of claim 1 , wherein the amount to attenuate is greater than zero based on the source of the audio being either AM, FM, CD or USB.

13. A method for attenuating an audio source in a vehicle for playback of mobile application statements in a vehicle computing system, the method comprising:
playing audio in the vehicle from one of a plurality of different audio sources;
receiving a wireless signal at the vehicle from the mobile computing device representative of an audible statement to be played in the vehicle;
determining an amount to attenuate the audio based on the audio source when the vehicle computing system is playing audio in the vehicle at the time the wireless signal is received from the mobile computing device; and
attenuating the playing audio and playing the audible statement.

14. The method of claim 13 , wherein the amount to attenuate is zero.

15. The method of claim 13 , wherein receiving the wireless signal from the mobile computing device utilizes an enhanced synchronous connection-oriented link.

16. The method of claim 13 , wherein receiving the wireless signal from the mobile computing device is accomplished via a synchronous connection-oriented link.

17. The method of claim 13 , wherein the method further includes receiving a caller identification from the mobile computing device identifying the mobile application.

18. The method of claim 17 , wherein the caller identification includes a calling line identification presentation.

19. The method of claim 13 , wherein the method further includes eliminating the attenuation of the playing audio after playing the audible statement.

20. A vehicle computing system (VCS) comprising:
a wireless transceiver communicating with a mobile device; and
a processor configured to:
play audio from multiple audio sources;
receive an instruction from the mobile device representative of an audible statement to be output by the VCS;
attenuate the playing audio a determined amount based upon the audio source that the VCS is playing in the vehicle at a time the instruction is received; and
play the audible statement.
