PROBLEM TO BE SOLVED: To prevent actual drive force from being excessively delayed against requested drive force or a vibration suppression effect from becoming insufficient due to an excessively large notch degree or an excessively small notch degree, while adjusting the notch degree to be an appropriate value corresponding to a travel situation of a vehicle.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 drive force; a drive force control unit 22 for controlling the drive device on the basis of instructed drive force; and a notch filter 24 for receiving a signal indicating 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 notch filter control unit 26 for variably setting a notch degree of the notch filter on the basis of plural travel parameters of the vehicle, and correcting the notch degree to a limit value when the notch degree exceeds the limit value.
【課題】ノッチ度が車両の走行状況に応じた適値になるようにしつつ、ノッチ度が過大又は過小になって要求駆動力に対し実際の駆動力が過剰に遅れたり振動抑制効果が不足したりすることを防止すること。【解決手段】運転者の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、車両の複数の走行パラメータに基づいてノッチフィルタのノッチ度を可変設定し、ノッチ度が限界値を越えるときには、ノッチ度を限界値に補正するノッチフィルタ制御装置26を有する。【選択図】図1
