To provide a method of generating a database for preview damping control, which is improved so that a target control force for reducing vibration of sprung mass does not exceed a maximum output of an actuator even in a condition that vertical displacement of a road surface is very large.SOLUTION: The method of generating a database for preview damping control includes: acquiring road surface displacement-related information S310; acquiring position information allowing for identification of a position where the road surface displacement-related information is detected S320; calculating a road surface displacement-related value relating to vertical displacement of a road surface on the basis of the road surface displacement-related information S340; storing a set of data associating the road surface displacement-related value and the position information with each other into a storage device as a part of the database S370; and making a downward correction of the magnitude of the road surface displacement-related value S360 before the step of storing the set of data into the storage device if it is determined that the magnitude of the road surface displacement-related value exceeds a preset allowable reference value S350 (Yes).SELECTED DRAWING: Figure 3
【課題】ばね上の振動を低減するための目標制御力が、路面の上下変位が非常に大きい状況においても、アクチュエータの最大出力を越えないよう改善されたプレビュー制振制御用データベース作成方法を提供する。【解決手段】プレビュー制振制御用データベース作成方法において、路面変位関連情報を取得しS310、路面変位関連情報が検出された位置を特定可能な位置情報を取得しS320、路面変位関連情報に基づいて路面の上下変位に関連する路面変位関連値を演算しS340、路面変位関連値と位置情報とが紐づけられたデータのセットをデータベースの一部として記憶装置に記憶するS370、路面変位関連値の大きさが予め設定された許容基準値を越えると判定されたときにはS350(Yes)、データのセットを記憶装置に記憶するステップに先立って、路面変位関連値の大きさを低減修正するS360。【選択図】図3
