Title:
ACTIVE VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3402120
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To suppress reduction of an accuracy of identification process by monitoring power supply voltage, and correcting an amplitude of a fixing control signal in a small level, in the case where power supply voltage is reduced more than a prescribed value, in a device formed in such a constitution that control vibration interfered with vibration generated from a vibration source is generated from a control vibration source.
SOLUTION: An engine 30 is supported to a suspension member 35 and the like of a car body through an active engine mount 1 for generating active supporting force according to a driving signal. The active engine mount 1 is provided with an electromagnetic actuator for generating damping force, and is formed in, such a constitution that prescribed electromagnetic force is generated according to a driving current signal (I) from a controller 25 so as to suppress vibration. In the controller 25, when an identification process start switch 28 is operated, vibration reducing process is stopped, and the identification process of a transmitting function is started. In this time, power supply voltage is monitored, and the identification process is carried out after an amplitude of the identification signal is corrected in a small level in the case where the power supply voltage value is not within a prescribed range.
