PROBLEM TO BE SOLVED: To provide the oscillation control method of a oscillation isolation device which can adequately control the oscillation of a vehicle in a period from its idling to its running operation, and also provide an oscillation control device thereof. SOLUTION: The oscillation control device 20 of an engine mount 15, which electrically controls an oscillation control system, comprises a microcomputer and so on and is provided with; a frequency determination part 21; a setting frequency determining and switching part 22; a map control part 23; and an adaptation control part 24 using a DXHS LMS filter. The frequency determination part 21 receives a pulse signal from an engine, determines that it is a control object frequencyω, and outputs the input signal x of the control object frequency. The setting frequency determining and switching part 22 determines whether the frequency of the input signal x is not larger than a setting frequency fs or larger than the setting frequency fs. When the frequency of the input signal x is not larger than the setting frequency fs, the input signal x is inputted into the map control part 23. When the frequency of the input signal x is larger than the setting frequency fs, the input signal x is inputted into the adaptation control part 24. COPYRIGHT: (C)2005,JPO&NCIPI
