    • 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.

    • 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).
    • ACM_ECU(200)基于来自TDC传感器(Sb)和曲柄脉冲传感器(Sa)的信号输出来估计发动机振动的第一周期(C1)中的发动机振动状态,并且计算具有 循环长度(T1)。 然后,ACM_ECU(200)以恒定的采样率对目标电流值波形进行采样,从而获得例如用于驱动主动控制装置(MF)的驱动单元的目标电流值(Fr_ICMD)的数据的集合 前侧(Fr侧)。 之后,ACM_ECU(200)基于预定数量的曲柄脉冲间隔来估计发动机振动的第三周期(C3)的周期长度(T3'),该定时在目标电流值( Fr_ICMD)输出到驱动单元(41)。 所获得的目标电流值的数据的总和被校正为与估计的周期长度(T3')相对应并被馈送到驱动单元(41)。
