To provide a vibration damping device for a vehicle capable of continuing control over a first damping force variable damper and a second damping force variable damper even if an abnormality occurs in a first acceleration sensor or a second acceleration sensor.SOLUTION: A control device 21 is connected to bogie side acceleration sensors 14A to 14D and vehicle body side acceleration sensors 15A to 15D. The control device 21 varies damping forces of first dampers 9A to 9H and second dampers 12A to 12D on the basis of acceleration information from the bogie side acceleration sensors 14A to 14D and the vehicle body side acceleration sensors 15A to 15D. Also, the control device 21 detects an abnormality of the bogie side acceleration sensors 14A to 14D and the vehicle body side acceleration sensors 15A to 15D. The control device 21 complements acceleration information of one of the bogie side acceleration sensors 14A to 14D and the vehicle body side acceleration sensors 15A to 15D with acceleration information from the other of the bogie side acceleration sensors 14A to 14D and the vehicle body side acceleration sensors 15A to 15D, when detecting an abnormality in one of the bogie side acceleration sensors 14A to 14D and the vehicle body side acceleration sensors 15A to 15D.SELECTED DRAWING: Figure 1

    【課題】第1加速度センサまたは第2加速度センサに異常が発生しても、第1減衰力可変ダンパと第2減衰力可変ダンパの制御を継続できる車両用制振装置を提供する。【解決手段】制御装置21は、台車側加速度センサ14A-14Dと車体側加速度センサ15A-15Dとに接続されている。制御装置21は、台車側加速度センサ14A-14Dと車体側加速度センサ15A-15Dとからの加速度情報に基づいて、第1ダンパ9A-9Hと第2ダンパ12A-12Dとの減衰力を可変する。また、制御装置21は、台車側加速度センサ14A-14Dと車体側加速度センサ15A-15Dの異常を検出する。制御装置21は、台車側加速度センサ14A-14Dと車体側加速度センサ15A-15Dの一方の加速度センサに異常を検出したとき、他方の加速度センサからの加速度情報により、一方の加速度センサの加速度情報を補完する。【選択図】図1
