Title:
ACTIVE VIBRATION CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JP3598888
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an active vibration controller for vehicle, which can avoid a situation where the effect of vibration reduction control is reduced.
SOLUTION: When a residual vibration signal (e) is read in step 107, a system is moved to step108. The residual vibration signal (e) is high-pass-filtered. The cutoff frequency of a high pass filter processing is set to be 5 Hz, for example. The system is moved to step 109 and a counter (j) is cleared to be zero. The system is moved to step 110 and the filter coefficient of an adaptive digital filter is updated by using the residual vibration signal (e) which is high-pass- filtered in step 108.
