Abstract

A vehicle system includes a navigation module, a memory, and a processor. The navigation module provides a vehicle velocity signal. An audio control program resides in the memory. The processor is programmed to execute the audio control program to adjust an audio parameter in the vehicle system.

Claims

1. A vehicle system comprising:

a navigation module that determines a vehicle velocity;

a memory that stores a velocity dependent audio control program and a velocity dependent audio parameter; and

a processor in communication with the navigation module and the memory that is operable to;

receive the vehicle velocity from the navigation module;

to determine an adjustment to an audio parameter using the velocity dependent audio control program, based on the vehicle velocity and the velocity dependent audio parameter; and

update the audio parameter based on the adjustment.

2. The vehicle system of claim 1, where the vehicle velocity is an instantaneous, momentary, or current vehicle velocity.

3. The vehicle system of claim 1, further comprising wheel sensors that interface the navigation module.

4. The vehicle system of claim 1, where the velocity dependent audio parameter comprises a manual control.

5. The vehicle system of claim 1, where the memory stores a velocity dependent noise control program, and the processor is further operable to update a second audio parameter based on the vehicle velocity and an output from a microphone.

6. The vehicle system of claim 5, where the processor is programmed to calculate the velocity dependent noise parameter at a single point in time, periodically in time, or continuously in time.

7. The vehicle system of claim 5, where the velocity dependent audio parameter is controlled automatically through the velocity dependent noise control program.

8. The vehicle system of claim 5, where the processor is further programmed to calculate the audio parameter adjustment based on the velocity dependent noise parameter.

9. The vehicle system of claim 5, where the velocity dependent noise parameter is manually preset by a user of the vehicle system.

10. The vehicle system of claim 1, where the velocity dependent audio parameter comprises profile data.

11. The vehicle system of claim 10, where the profile data comprises external condition data or data associated with the user occupant.

12. The vehicle system of claim 1, where a signal input controls whether the adjustment to the audio parameter occurs.

13. The vehicle system of claim 1, further comprising an audio module that receives and processes the adjustment to the audio parameter.

14. The vehicle system of claim 13, where the audio module comprises an entertainment and comfort device.

15. A method for updating an audio parameter to an audio module, the method comprising:

polling a navigation module for a vehicle velocity;

determining a velocity dependent audio parameter;

determining an adjustment to an audio parameter based on the vehicle velocity and the velocity dependent audio parameter; and

updating the audio parameter based on the adjustment.

16. The method of claim 15, where determining the velocity dependent audio parameter comprises:

polling a microphone for noise;

receiving the vehicle velocity;

determining an adjustment to the velocity dependent audio parameter based on the vehicle velocity and a detected noise; and

adjusting the velocity dependent audio parameter based on the velocity dependent audio parameter adjustment.

17. The method of claim 15, where determining the adjustment to the audio parameter is further based on a velocity dependent noise parameter.

18. The method of claim 17, where determining the velocity dependent noise parameter comprises:

polling a microphone to detect noise;

receiving the vehicle velocity; and

determining the velocity dependent noise parameter based on the vehicle velocity and a level of detected noise.

19. The method of claim 17, where the velocity dependent noise parameter is determined by a processor at a single point in time, periodically in time, or continuously in time.

20. The method of claim 17, where the velocity dependent noise parameter is manually preset by a user of the vehicle system.

21. The method of claim 15, where the vehicle velocity is an instantaneous, momentary, or current vehicle velocity.

22. The method of claim 15, where the navigation module interfaces wheel sensors and gyroscopes that provide data used to determine the vehicle velocity.

23. The method of claim 15, where the velocity dependent audio parameter is manually controlled.

24. The method of claim 15, where the velocity dependent audio parameter is associated with an external condition, an occupant, or profile data.

25. A vehicle system comprising:

a navigation device that determines a vehicle velocity;

a memory that stores a velocity dependent audio parameter; and

means for determining an audio parameter adjustment from the vehicle velocity and the velocity dependent audio parameter.

26. A velocity dependent audio module control product comprising:

a machine readable medium; and

instructions encoded on the machine readable medium, the instructions comprising;

instructions that map a navigation determined vehicle velocity to an adjustment to an audio parameter; and

modification instructions that adjust the audio parameter.
