ACTIVE NOISE CONTROL SYSTEM IN THE CABIN OF A MOTOR VEHICLE

摘要

The system has a controller (2) capturing noise measured by a microphone (1) and vehicle parameters for establishing noise calibration tables within a master audio (3), where the microphone is a hands-free kit of the master audio. A speaker (4) of a vehicle information system generates noise in phase opposition with the noise present in a vehicle passenger compartment to limit or cancel the compartment noise. The controller is programmed such that information is dynamically and progressively updated in the tables, where calibration is performed as a measure of use of the vehicle.
