Abstract
An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.
