Classification: CPC B | IPC B

Claim 0:
1. A damping control device for a vehicle, comprising:
a control force generating device configured to generate a vertical control force for damping a sprung portion of the vehicle between at least one wheel and a portion of a vehicle body that corresponds to a position of the wheel; and
an electronic control unit configured to control the control force generating device and to change the control force, wherein
the electronic control unit is configured to:
acquire, as a preview condition amount, an unsprung condition amount at a predicted passing position where the wheel of the vehicle is predicted to pass at a timing when a predetermined period has elapsed from a current time, based on preview reference data being sets of data in which unsprung condition amounts and pieces of positional information are linked to each other, the unsprung condition amounts indicating a displacement condition of an unsprung portion actually displaced in a vertical direction due to a displacement of a road surface that is acquired when at least one of the vehicle and another vehicle has actually traveled on the road surface, the pieces of positional information being available to determine a position of the wheel when the unsprung condition amount is acquired; and
execute, at a timing when the wheel passes through the predicted passing position, preview damping control for controlling the control force generating device to cause the control force generated by the control force generating device to agree with a target control force being a target value of the control force that is calculated based on the preview condition amount,

wherein the preview reference data is wirelessly acquired by the electronic control unit from a storage device of a management server.
