Method and apparatus for active noise shedding

摘要

A method for reducing audible noise in a vehicle audio component includes steps of: determining that the audio component is or is about to be operating in a susceptible mode wherein it is likely to receive electrical interference caused by an electrical component operating in an interfering operating state; communicating to the electrical component that the audio component is operating in the susceptible mode; and changing operation of the electrical component from the interfering operating state to a non-interfering operating state less likely to generate electrical signals causing audible noise.

1. A method of reducing noise in a vehicle audio system comprising:
determining that a vehicle audio system radio receiver is operating in a susceptible mode wherein it is susceptible to electrical interference caused by a vehicle electrical component having no wireless communications capability operating in an interfering state, the vehicle electrical component and the radio receiver both connected to an electronic communication bus of a motor vehicle; sending a mode message to the vehicle electrical component via the communication bus that the radio receiver is in the susceptible mode; and changing operation of the vehicle electrical component to a non-interfering state less likely to cause electrical interference.
