To enhance the anti-vibration performance within a vehicle interior by suppressing transmission of vibrations of a sub frame to a vehicle body via a plurality of mounts.SOLUTION: A vehicular anti-vibration device 11 includes: a sub frame 13 to which vibrations of wheels 2 are transmitted; a plurality of mounts 15FL, 15FR, 15RL and 15RR which are arranged between the sub frame 13 and a vehicle body 4, and are configured to change rigidities in a predetermined direction when exciting currents IFL, IFR, IRL and IRR are supplied; and a control device 18 that controls the exciting currents IFL, IFR, IRL and IRR supplied to the plurality of mounts 15FL, 15FR, 15RL and 15RR. The control device 18 sets a target elastic center of the sub frame 13, and individually calculates the exciting currents IFL, IFR, IRL and IRR supplied to the plurality of mounts 15FL, 15FR, 15RL and 15RR so as to make an actual elastic center of the sub frame 13 consistent with the target elastic center.SELECTED DRAWING: Figure 1

    【課題】サブフレームの振動が複数のマウントを介して車体に伝達されることを抑制することで、車室内の防振性能を高める。【解決手段】車両用防振装置11は、車輪2の振動が伝達されるサブフレーム13と、サブフレーム13と車体4との間に配置され、励磁電流IFL、IFR、IRL、IRRが供給されることで所定方向の剛性が変化するように構成された複数のマウント15FL、15FR、15RL、15RRと、複数のマウント15FL、15FR、15RL、15RRに供給される励磁電流IFL、IFR、IRL、IRRを制御する制御装置18と、を備え、制御装置18は、サブフレーム13の目標弾性中心を設定し、サブフレーム13の実際の弾性中心を目標弾性中心と一致させるべく、複数のマウント15FL、15FR、15RL、15RRに供給される励磁電流IFL、IFR、IRL、IRRを個別に算出する。【選択図】図1
