PROBLEM TO BE SOLVED: To set responsiveness of vehicular drive force against a drive operation to responsiveness appropriate for respective shift positions and respective travel modes, while suppressing a vehicle vibration effectively as far as possible, in a vehicle including a motor as a drive source for controlling a drive unit with instructed drive force in which a frequency component of a vibration of a vehicle body is reduced by a notch filter.SOLUTION: A vehicle body vibration control device 10 includes: a requested drive force computation unit 20 for computing drive force requested by a driver; a drive unit 16 including a motor EM and 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 a vehicle body 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 according to a shift position or a travel mode unique to the vehicle including the motor.
【課題】ノッチフィルタにより車体の振動の周波数成分が低減された指令駆動力にて駆動装置を制御する駆動源として電動機を含む車両において、車体振動をできるだけ効果的に抑制しつつ、駆動操作に対する車両の駆動力の応答性を各シフト位置や各走行モードに適した応答性にする。【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、電動機EMを含み車両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、電動機を含む車両に固有のシフト位置又は走行モード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
