Abstract

A noise cancellation system for a vehicle includes a sensor configured to determine an imminent noise that will be perceivable in a passenger compartment of the vehicle, a noise identification module operable to identify at least one quality of the imminent noise, and a noise cancellation device operable to substantially attenuate the imminent noise as the imminent noise becomes a perceivable noise in the passenger compartment based on the at least one quality of the imminent noise.

First claim

What is claimed is:

1. A noise cancelation system for a vehicle comprising:
a sensor configured to determine an imminent noise before being perceivable in a passenger compartment of the vehicle;
a noise identification module operable to identify at least one quality of the imminent noise; and
a noise cancellation device operable to substantially attenuate the imminent noise as the imminent noise becomes a perceivable noise in the passenger compartment based on the at least one quality of the imminent noise.

2. The noise cancellation system according to claim 1 , wherein the sensor comprises a camera.

3. The noise cancellation system according to claim 2 , wherein the camera is mounted at a forward portion of the vehicle.

4. The noise cancellation system according to claim 3 , wherein the forward portion of the vehicle comprises a front body feature of the vehicle.

5. The noise cancellation system according to claim 4 , wherein the front body feature comprises a front bumper.

6. The noise cancellation system according to claim 1 , wherein the sensor comprises an accelerometer.

7. The noise cancellation system according to claim 6 , wherein the accelerometer is mounted to a forward suspension component of the vehicle.

8. The noise cancellation system according to claim 6 , wherein the accelerometer is mounted to a forward drive component of the vehicle.

9. A vehicle comprising:
a body including a forward body feature;
a forward suspension component;
a forward drive component;
a passenger compartment; and
a noise cancellation system comprising:
a sensor configured to detect an imminent noise before being perceivable in a passenger compartment of the vehicle;
a noise identification module operable to identify at least one quality of the imminent noise; and
a noise cancellation device operable to substantially attenuate the imminent noise as the imminent noise becomes a perceivable noise in the passenger compartment based on the at least one quality of the imminent noise.

10. The vehicle according to claim 9 , wherein the sensor comprises a camera.

11. The vehicle according to claim 10 , wherein the camera is mounted at a forward portion of the vehicle.

12. The vehicle according to claim 11 , wherein the forward portion of the vehicle comprises a front body feature of the vehicle.

13. The vehicle according to claim 12 , wherein the front body feature comprises a front bumper.

14. The vehicle according to claim 9 , wherein the sensor comprises an accelerometer.

15. The vehicle according to claim 14 , wherein the accelerometer is mounted to one of a forward suspension component and a forward drive component of the vehicle.

16. The vehicle according to claim 9 , further comprising: an internal communication system, the noise cancellation system attenuating the perceivable noise to enhance sound quality for the internal communication system.

17. A computer program product for cancelling noise produced between a vehicle and a road surface, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions being executable by a computer processor to cause the computer processor to:
detect an imminent noise before the noise is perceivable in the vehicle;
identify the imminent noise;
determine an abatement strategy; and
generate a cancellation frequency that substantially suppresses the imminent noise as the imminent noise becomes a perceivable noise in a passenger compartment.

18. The computer program product of claim 17 , wherein the program instructions cause the computer processor to identify the imminent noise by receiving signals produced by an accelerometer.

19. The computer program product of claim 18 , wherein the program instructions cause the computer processor to identify the imminent noise by receiving signals produced by the accelerometer at one of a forward drive component and a forward suspension component of the vehicle.

20. The computer program product of claim 17 , wherein the program instructions cause the computer processor to identify the imminent noise by receiving image data of the road surface through a camera.
