PROBLEM TO BE SOLVED: To effectively suppress a vehicle body vibration while satisfying a drive request of a driver.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 unit 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 the vehicle is reduced and outputting the processed signal as a signal indicating the instructed drive force to the drive force control unit. The device further includes a notch filter control unit 26 for variably setting a notch degree of the notch filter according to whether the requested drive force of the driver increases or not.
【課題】運転者の駆動要求を満たしつつ車体振動を効果的に抑制すること。【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、運転者の要求駆動力が増加しているか否かに基づいてノッチフィルタのノッチ度を可変設定するノッチフィルタ制御装置26を有する。【選択図】図1
