Title:
ACTIVE VIBRATION AND NOISE CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2009062024
Kind Code:
A
Abstract:

To provide an active vibration and noise control device for a vehicle, which simultaneously and consistently muffles the road noise of 40 Hz and 70 Hz.

The active vibration and noise control device for the vehicle subtracts the first control signal Sc1 to be outputted from a first band pass filter 56 from the error signal e1 by a subtracter 120, and feeds the difference to a second band pass filter 156. Thus, the second band pass filter 156 having the center frequency at 70 Hz is affected by the operation of the first band pass filter 56 having the center frequency at 40 Hz (the first control signal Sc1). The stability of the first band pass filter 56 is guaranteed because it is not affected by the operation of the second band pass filter 156 (the second control signal Sc2).
