Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a vibration damping control device for effectively damping vibration above a spring while effectively preventing overcharge of a battery even when the vibration above the spring includes a high frequency component.SOLUTION: A vibration damping control device 10 for a vehicle includes: a battery 34; an electric motor 18 for applying driving force to front wheels 28FL, 28FR by using electricity from the battery; and a control device 40 for calculating target vibration damping torque Tdt for vibration damping above a spring and controlling the electric motor and a regenerative braking device so that vibration damping torque generated by driving torque and regenerative braking torque of the electric motor becomes the target vibration damping torque. The electric motor, an inverter 32 and the control device function as the regenerative braking device for charging the battery by using electricity generated by applying braking force to the right and left front wheels through regenerative braking. When the charge amount of the battery is a reference value or larger and a sum of the driving torque of the electric motor for traveling the vehicle and the target vibration damping torque is braking torque, the target vibration damping torque is corrected to a value Tdtf after low-pass filter processing.SELECTED DRAWING: Figure 1
【課題】ばね上の振動が高周波成分を含む場合にも、バッテリの過充電を効果的に防止しつつ、ばね上の振動を効果的に制振する制振制御装置を提供する。【解決手段】車両の制振制御装置10は、バッテリ34と、バッテリからの電気を使用して前輪28FL、28FRに駆動力を付与する電動機18と、ばね上制振のための目標制振トルクTdtを演算し、電動機の駆動トルク及び回生制動トルクによる制振トルクが目標制振トルクになるように電動機及び回生制動装置を制御する制御装置40と、を含む。電動機、インバータ32及び制御装置は、回生制動により左右の前輪に制動力を付与し発生する電気にてバッテリを充電する回生制動装置として機能する。バッテリの充電量が基準値以上であり、かつ、車両走行用の電動機の駆動トルクと目標制振トルクとの和が制動トルクであるときには、目標制振トルクがローパスフィルタ処理後の値Tdtfに修正される。【選択図】図1 |
