ABSTRACT:
A method for actuating active vibration insulators includes the steps of generating an idling control signal in an idling range of a vehicle, generating a running control signal in a running range of the vehicle, and actuating an electromagnetic actuator of an active vibration insulator based on the idling control signal or the running control signal, thereby inhibiting vibrations of a vehicle engine from transmitting by the electromagnetic actuator. The idling control signal is produced by adding a higher order harmonic signal component with respect to a control frequency, based on a cyclic pulsating signal emitted from the vehicle engine, to a fundamental-wave signal component of the control frequency. The running control signal is composed of the fundamental-wave signal component of the control signal. The method can inhibit noises from generating by actuating simple electromagnetic actuators, and can damp vibrations of vehicle engines simply and less expensively.
