To provide a preview damping control apparatus and method capable of damping a sprung part by reading effective road surface information in advance, even without a large number of vehicles traveling on the same road at various lateral positions.SOLUTION: Road surface displacement-related information corresponding to left and right wheels which has been detected by a pair of on-vehicle detection devices is transmitted to a preview reference database control device together with detection position information, and a preview reference database including road surface displacement-related values is created. An on-vehicle control unit uses the road surface displacement-related values in the preview reference database to perform preview damping control for reducing the vibration of the sprung part of a vehicle. It is assumed that road surface displacement-related values in predetermined adjacent regions located in a direction crossing the traveling direction of the vehicle with respect to two points where the road surface displacement-related information has been detected by the pair of detection devices are the same as the in-phase components of the road surface displacement-related values at the two points.SELECTED DRAWING: Figure 5

    【課題】多数の車両が同一の道路を様々な横方向位置にて走行しなくても、有効な路面情報を先読みしてばね上を制振することができるプレビュー制振制御装置及び方法を提供する。【解決手段】車載の一対の検出装置により検出された左右の車輪に対応する路面変位関連情報が検出位置の情報と共にプレビュー参照データベース制御装置へ送信され、路面変位関連値を含むプレビュー参照データベースが作成される。車載の制御ユニットは、プレビュー参照データベースの路面変位関連値を使用して車両のばね上の振動を低減するプレビュー制振制御を行う。一対の検出装置により路面変位関連情報が検出された二つの地点に対し車両の進行方向を横切る方向に位置する所定の隣接領域の路面変位関連値が、二つの地点の路面変位関連値の同相成分と同一であると仮定される。【選択図】図5
