PROBLEM TO BE SOLVED: To prevent command drive force from being excessively deviated from requested drive force while securing a high vehicle body vibration control effect as far as possible.SOLUTION: A vehicle body vibration control device 10 of a vehicle includes: a requested drive force calculation unit 20 which calculates requested drive force of a driver; a drive unit 16 which imparts drive force to a vehicle 12; a drive force control unit 22 which controls the drive unit on the basis of instructed drive force; and a notch filter 24 which receives a signal indicating the requested drive force, processes the signal indicating the requested drive force so that a frequency component of the vibration of a vehicle body is reduced, and outputs the processed signal to the drive force control unit as a signal indicating the instructed drive force. The vehicle body vibration control device also includes an instructed drive force limit unit 30 which limits a magnitude of the instructed drive force on the basis of a limit value for limiting the deviation of the instructed drive force from the requested drive force of the driver.
【課題】できるだけ高い車体制振効果を確保しつつ、指令駆動力が要求駆動力から過剰に乖離することを防止する。【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、運転者の要求駆動力からの指令駆動力の乖離を制限するための制限値に基づいて指令駆動力の大きさを制限する指令駆動力制限装置30を有する。【選択図】図1
