1. A suspension control system comprising:

  • a suspension, which suspends a wheel on a vehicle body;

    an actuator, which changes a damping force of a damper of the suspension;

    an acceleration sensor, which detects at least one of a lateral acceleration and a longitudinal acceleration of a vehicle;

    acceleration derivative value calculating means, which differentiates the acceleration detected by the acceleration sensor to calculate an acceleration derivative value;

    target electrical current calculating means, which calculates, based on the acceleration derivative value, a target electrical current to be supplied to the actuator;

    a damper displacement sensor, which detects a damper displacement; and

    damper speed calculating means, which calculates a damper speed based on the damper displacement detected by the damper displacement sensor,wherein the target electrical current calculating means corrects the target electrical current based on the damper speed.
