Title:
VIBRATION DAMPING DEVICE AND VEHICLE PROVIDED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2011/065441
Kind Code:
A1
Abstract:
Provided is a vibration damping device wherein vibration damping properties and stability are improved even in a case where the frequency of a vibration to be damped is erroneously recognized as a frequency different from an actual frequency. When an offsetting vibration (Vi4) is to be offset at a position-requiring-vibration-damping (pos), the vibration damping device performs operations wherein an adaptation control algorithm is used to calculate a pseudo-vibration (Vi3') required to offset a vibration (Vi3) transmitted to the position-requiring-vibration-damping from a vibration generating source (gn), wherein the offsetting vibration is generated at the position-requiring-vibration-damping via a vibration excitation means (2) on the basis of the pseudo-vibration calculated, wherein detection is made of a vibration (Vi3 + Vi4) which is a vibration left over as an offset error between the offsetting vibration generated and the vibration at the position-requiring-vibration-damping, and wherein the adaptation control algorithm is subjected to learning-adaptation so that the vibration left over as the detected offset error is reduced. The vibration damping device comprises a frequency recognition means (31) for performing an operation wherein the frequency of a vibration at the position-requiring-vibration-damping is recognized on the basis of a vibration generating source-related signal generated at the vibration generating source, the aforementioned frequency being intended to be used as a basis of the frequency of the pseudo-vibration; a phase difference identification means (34) for identifying the phase difference (Δφ) between the phase of the offsetting vibration and the phase of the vibration left over as the offset error at the position-requiring-vibration-damping; and a frequency correction means (35) for performing an operation wherein a frequency recognized by the frequency recognition means on the basis of the phase difference identified is corrected in a direction where the phase difference vanishes.
