摘要： In an active anti-vibration supporting device (301), an ACM_ECU (200) for estimating an engine vibration state by using output data from a crank pulse sensor (Sa) and a TDC sensor (Sb) drives a driving unit (41) so as to extend and contract and thereby suppresses the transmission of vibration. The ACM_ECU (200) calculates the number of STGs (S1F) that is a quotient obtained when dividing the phase delay (P1F) of a target current value waveform by an average STG time ((T1)/4) in a first cycle (C1) of engine vibration and the remaining time (P′1F) of the phase delay (P1F), wherein the target current value waveform is used for suppressing the transmission of the engine vibration calculated using the output data from the crank pulse sensor (Sa) and the TDC sensor (Sb). The timing at which the elapse of the STG time equivalent to the number of STGs (S1F) in a third cycle (C3) of the engine vibration in the driving timing of the driving unit has been detected is set as a phase delay reference. Further, after the remaining time (P′1F) has elapsed, the target current value waveform is output.

摘要： The natural vibration frequency of a roll resonance which does not occur since the engine rotation number is high in a normal operation range of an engine is detected at the time of engine start or stop when the engine rotation number is lower than the normal operation range, and thus the natural vibration frequency of the roil resonance can be detected with a good accuracy. A current is generated by an electromotive force of an actuator of the active vibration isolation support device excited by the engine immediately before stopping its rotation, and the frequency of the current is used to detect the natural vibration frequency of the engine, and the roll resonance of the engine is suppressed by controlling the operation of the active vibration isolation support device at the time of engine start based on the natural vibration frequency, thereby not only eliminating the need of a specific frequency detection sensor, but also effectively reducing the vibration at the time of engine start when the roll resonance becomes strong.
