Title:
ACTIVE VIBRATION NOISE CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP3661063
Kind Code:
B2
Abstract:
PURPOSE: To provide an active vibration noise control device which has a multi- channel active vibration noise control function and in which quantity of operation is reduced, the result of vibration noise reduction can be sufficiently improved even by an operation processor having low performance, a manufacturing cost is reduced, and sufficient performance for a vehicle is provided.
CONSTITUTION: In an active vibration noise control device for a vehicle provided with plural filter coefficient changing means MEFX-LMS, one of plural MEFX- LMS or more are selected by a control means. A filter coefficient of a corresponding adaptive filter is changed by this selected MEFX-LMS based on reference signals from corresponding reference signal generating means 1-4 and error signals from error detecting means 13, 14, respectively corresponding reference signals are filtered by an adaptive filter having a filter coefficient after changing and adaptive filters other than this, cancel signals are generated, converted to canceling vibrations by canceling vibration generating means 11, 12, and outputted to the inside of a vehicle.
