PROBLEM TO BE SOLVED: To reduce a possibility that a driver feels discomfort due to a delay of a change of drive force when the driver performs a shift operation and a change operation of a traveling mode, while effectively suppressing vehicle body vibration as much 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 of the vehicle also includes an instructed drive force correction unit 30 which corrects the instructed drive force to the requested drive force of the driver when either of a predetermined shift change operation and a predetermined change operation of a vehicle traveling mode is performed.
【課題】車体振動をできるだけ効果的に抑制しつつ、運転者がシフト操作や走行モードの変更操作を行った場合に駆動力の変化の遅れに起因して違和感を覚える虞れを低減する。【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、予め決定されたシフトチェンジ操作及び予め決定された車両走行モードの変更操作の何れかが行われたときには、指令駆動力を運転者の要求駆動力に修正する指令駆動力修正装置30を有する。【選択図】図1
