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.
Claims20
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.
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.
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.
