1. A suspension control system comprising:
an actuator that adjusts a suspension stroke of a control target wheel of a vehicle; and
a control device that controls the actuator, wherein:
the control device includes
an acquisition unit that acquires, from a road surface data map in which a road surface displacement-associated value associated with vertical displacement of a road surface is associated with a position, a road surface displacement-associated value at a predicted passing position of the control target wheel a predetermined time after a present time,
a calculation unit that calculates a target control force based on the acquired road surface displacement-associated value, and
a control unit that controls the actuator such that a control force generated by the actuator coincides with the target control force when the control target wheel passes the predicted passing position; and
the calculation unit calculates the target control force such that an amount of change in the target control force per unit time becomes smaller when a blinker of the vehicle starts operating than when the blinker is not operating.
