Title:
ACTIVE ANTI-VIBRATION SUPPORTING DEVICE AND ANTI-VIBRATION CONTROL METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2011/004784
Kind Code:
A1
Abstract:
An ACM_ECU (200) estimates an engine vibration state in a first cycle (C1) of engine vibration on the basis of signal outputs from a TDC sensor (Sb) and a crank pulse sensor (Sa) and calculates a target current value waveform having a cycle length (T1). The ACM_ECU (200) then samples the target current value waveform at a constant sampling rate, thereby obtaining, for example, an aggregate of the data of target current values (Fr_ICMD) for a driving unit for driving an active control mount (MF) on the front side (Fr side). After that, the ACM_ECU (200) estimates the cycle length (T3') of a third cycle (C3) of the engine vibration on the basis of a predetermined number of crank pulse intervals at a timing when the data of the target current values (Fr_ICMD) are output to the driving unit (41). The obtained aggregate of the data of target current values is corrected so as to correspond to the estimated cycle length (T3') and fed to the driving unit (41).
