Abstract
A damper control device includes a rate sensor that detects a pitching angular velocity of a vehicle body, a vehicle speed sensor, a steering angle sensor and a calculation unit that detect a roll angle and a yaw angular velocity of the vehicle body, a pressure sensor that detects a pressure of a contraction-side chamber in a front-wheel side damper, a pressure sensor that detects a pressure of a contraction-side chamber in a rear-wheel side damper, and a correction unit that corrects the pitching angular velocity. The pressures are controlled on the basis of the corrected pitching angular velocity and the pressures. The vehicle speed sensor, the steering angle sensor and the calculation unit detect the roll angle and the yaw angular velocity on the basis of a traveling speed and a steering angle.
