ABSTRACT:
A vibration
oise active control system for automotive vehicles which generates a canceling signal for canceling vibrations and noises generated within the compartment of the vehicle, based on a reference signal related to the vibrations and noises by means of an adaptive filter. The canceling signal is converted into a canceling sound. The adaptive filter has a filter coefficient thereof changed based on the cancellation error between the canceling sound and the vibrations and noises within the compartment, detected by an error sensor, and the reference signal. A memory stores a plurality of filter coefficient values of the adaptive filter corresponding to a plurality of predetermined traveling conditions of the vehicle. A discriminator reads out a filter coefficient value of the adaptive filter corresponding to the detected predetermined traveling condition of the vehicle, supplies the read-out filter coefficient value to the adaptive filter to generate the canceling signal, and stores a filter coefficient value of the adaptive filter which has been changed based on the generated canceling signal.
