Patent ID: 7010420

Claim:
A vibration controller for active vibration insulators, the vibration controller comprising: a data map storage for storing a data map prepared in advance, the data map comprising amplitude and/or phase data with respect to torque values of a vehicle engine; means for detecting actual torque values of the vehicle engine; means for determining one of the amplitude and/or phase data with respect to one of the actual torque values based on the data map; a signal generator for generating a control signal based on cyclic pulsating signals emitted from the vehicle engine, the control signal comprising an amplitude and a phase, and updating the amplitude and/or phase of the control signal based on the one of the determined amplitude and/or phase data; and an actuator for actuating an electromagnetic actuator of an active vibration insulator based on the updated control signal, whereby inhibiting vibrations of the vehicle engine from transmitting by means of vibrating forces exerted by the electromagnetic actuator.
