Title:
PREVIEW DAMPING CONTROL APPARATUS AND METHOD FOR VEHICLE
Document Type and Number:
Japanese Patent JP2022061856
Kind Code:
A
Abstract:
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 detected by an on-vehicle detection device 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 a road surface displacement-related value in a predetermined adjacent region located in a direction crossing the traveling direction of the vehicle with respect to a point where the road surface displacement-related information has been detected by the on-vehicle detection device is the same as the road surface displacement-related value at the point.SELECTED DRAWING: Figure 5
