1. A damper control device comprising:

  • a pitching angular velocity detection unit configured to detect a pitching angular velocity of a vehicle body of a two-wheeled vehicle;

    a roll angle detection unit configured to detect a roll angle of the vehicle body;

    a yaw angular velocity detection unit configured to detect a yaw angular velocity of the vehicle body;

    a front-wheel side pressure detection unit configured to detect a pressure of a contraction-side chamber in a front-wheel side damper, the front-wheel side damper being interposed between the vehicle body and a front-wheel of the two-wheeled vehicle;

    a rear-wheel side pressure detection unit configured to detect a pressure of a contraction-side chamber in a rear-wheel side damper, the rear-wheel side damper being interposed between the vehicle body and a rear-wheel of the two-wheeled vehicle; and

    a correction unit configured to correct the pitching angular velocity on the basis of the roll angle and the yaw angular velocity, the correction unit being configured to remove a component based on the roll angle and the yaw angular velocity from the detected pitching angular velocity during turning of the two-wheeled vehicle, whereinthe pressure of the contraction-side chamber in the front-wheel side damper and the pressure of the contraction-side chamber in the rear-wheel side damper are controlled on the basis of the corrected pitching angular velocity, the pressure of the contraction-side chamber in the front-wheel side damper, and the pressure of the contraction-side chamber in the rear-wheel side damper.
