Title:
能動型防振装置の制御方法及び制御装置
Document Type and Number:
Japanese Patent JP4172414
Kind Code:
B2
Abstract:
A vibration controller includes a data map storage, a detector, a determiner, a signal generator, and an actuator. The data map storage stores amplitude and/or phase data with respect to torque values of a vehicle engine as a data map in advance. The detector detects actual torque values of the vehicle engine. The determiner determines one of the amplitude and/or phase data with respect to one of the actual torque values based on the data map. The signal generator generates a control signal based on cyclic pulsating signals emitted from the vehicle engine, and updates the amplitude and/or phase of the control signal based on the one of the determined amplitude and/or phase data. The actuator actuates 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.
