Claim 6:
7. A damping control system comprising:
a vehicle configured to control a control force generating device to change a vertical control force for damping a sprung portion, the control force generating device being configured to generate the control force between at least one wheel and a portion of a vehicle body that corresponds to a position of the wheel; and
a management server having a storage device configured to connect to the vehicle via a wireless network, and prestores 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, wherein
the storage device is configured to provide the preview reference data wirelessly to the vehicle, and
the vehicle is configured to:
acquire, as a preview condition amount, an unsprung condition amount at a predicted passing position where the wheel is predicted to pass at a timing when a predetermined period has elapsed from a current time, based on the preview reference data provided by the storage device; 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 for damping the sprung portion, the target control force being calculated based on the preview condition amount.
