Road noise masking in a vehicle

A system for implementing road noise masking for a vehicle, the system comprising:

• a computer processor disposed in the vehicle and communicatively coupled to a vehicle bus;
• and
• logic executable by the computer processor, the logic configured to implement a method, the method comprising:
• determining an expected interior sound associated with the vehicle, the expected interior sound defined by a design of the vehicle in conjunction with road conditions encountered by the vehicle;
• monitoring, over the vehicle bus, information sources of the vehicle during a driving event;
• upon determining a current road surface from the monitoring:
• calculating a masking noise shape commensurate with the expected interior sound;
• and
• transmitting instructions including the masking noise shape to an audio system in the vehicle, the audio system producing masking noise from a tuner of the audio system that approximates the masking noise shape.

A computer program product for implementing road noise masking for a vehicle, the computer program product comprising a computer-readable storage medium having program code embedded thereon, which when executed by a computer processor, causes the computer processor to implement a method, the method comprising:

• determining, via a computer processor in the vehicle, an expected interior sound associated with the vehicle, the expected interior sound defined by a design of the vehicle in conjunction with road conditions encountered by the vehicle;
• monitoring, via the computer processor, information sources of the vehicle during a driving event;
• upon determining a current road surface from the monitoring:
• calculating a masking noise shape commensurate with the expected interior sound;
• and
• transmitting instructions including the masking noise shape to an audio system in the vehicle, the audio system producing masking noise from a tuner of the audio system that approximates the masking noise shape.
