PROBLEM TO BE SOLVED: To provide a vehicle damping controller capable of changing a filter promptly according to a change in a vehicle state, and capable of suitably suppressing the occurrence of vibration or noise.SOLUTION: There is provided a vehicle damping controller mounted on a vehicle travelling by transmitting to a drive wheel the power output from at least one of an internal combustion engine and a drive motor 2 via a transmission. The vehicle damping controller includes a torque command unit 50 for outputting a torque command value to a drive motor 2, and a control unit 40 having a plurality of filters 41, 42, and 43, each of which has a different filter coefficient, for extracting a signal indicating vibration or noise of the drive motor 2. The control unit 40 performs weighting among signals extracted by the filters 41, 42, and 43 on the basis of a change in a vehicle state, and corrects the torque command value on the basis of the signals that are weighted.SELECTED DRAWING: Figure 2 【課題】車両状態の変化に応じて速やかにフィルタを変更することができ、振動又は騒音の発生を好適に抑制することができる車両用制振制御装置を提供すること。【解決手段】内燃機関及び駆動モータ２の少なくとも一方から出力された動力を、変速機を介して駆動輪に伝達することにより走行する車両に搭載される車両用制振制御装置であって、駆動モータ２に対してトルク指令値を出力するトルク指令部５０と、駆動モータ２の振動又は騒音を示す信号を抽出する、それぞれフィルタ係数の異なる複数のフィルタ４１、４２及び４３を有する制御部４０とを備え、制御部４０が車両状態の変化に基づいて各フィルタ４１、４２及び４３によって抽出された信号間で重み付けを行い、重み付けがなされた信号に基づきトルク指令値を補正する。【選択図】図２
