Patent ID: 7747353

Claim:
A method of setting control data used in an active vibration isolation control system for attenuating vibration of a vehicle in such a manner that the control data, which is based on a periodical pulse signal emanating from a vibration-producing source of the vehicle, is applied to an active mount which is attached with a vibrator and which is mounted on a vehicle, the method comprising: using a control device which is associated only with the vehicle to set the control data selectively either by use of an adaptive control algorithm when a frequency of the pulse signal from the vibration-producing source of the vehicle is higher than a predetermined frequency or by selecting map-based control data from a data map for establishing a map-based control of the vibration when the pulse signal from the vibration-producing source of the vehicle is not higher than the predetermined frequency; using the control device to calculate a deviation between the map-based control data and actually detected data representing the vibration at a specific position of the vehicle; and using the control device to modify the map-based control data on a basis of the calculated deviation, wherein the control data is compensated on a basis of the modified map-based control data.
