PROBLEM TO BE SOLVED: To reduce a possibility of feeling that responsiveness of a drive unit is deteriorated against a drive operation even when request drive force is changed stepwise, while suppressing a vehicle body vibration effectively as far as possible.SOLUTION: A vehicle body vibration control device 10 of a vehicle includes: a requested drive force computation unit 20 for computing drive force requested by a driver; a drive unit 16 for providing a vehicle 12 with the drive force; a drive force control unit 22 for controlling the drive unit on the basis of instructed drive force; and a notch filter 24 for receiving a signal indicating the requested drive force, processing the signal indicating the requested drive force so that a frequency component of a vibration of a vehicle is reduced and outputting the processed signal as a signal indicating the instructed drive force to the drive force control unit. The device 10 further includes a correction unit 30 for correcting the notch filter so as to use a present value as data to be applied to filter processing when there is no need of correcting the instructed drive force to a value with effectiveness of filter processing reduced.

    【課題】車体振動をできるだけ効果的に抑制しつつ、要求駆動力が段差的に変化しても駆動操作に対する駆動装置の応答性が低下したと感じる虞れを低減する。【解決手段】運転者の要求駆動力を演算する要求駆動力演算装置20と、車両12に駆動力を付与する駆動装置16と、指令駆動力に基づいて駆動装置を制御する駆動力制御装置22と、要求駆動力を示す信号を受信し、車体の振動の周波数成分が低減されるよう要求駆動力を示す信号を処理し、処理後の信号を駆動力制御装置へ指令駆動力を示す信号として出力するノッチフィルタ24とを有する車両の車体振動制御装置10であって、指令駆動力をフィルタ処理の効果が低減された値に修正する必要性がなったときには、フィルタ処理に供されるデータとして現在値を使用するようノッチフィルタを修正する修正装置30を有する。【選択図】図1
