Abstract
A suspension controller includes a wheel speed sensor that detects the wheel speed of each wheel, a basic input amount calculating unit that calculates the basic input amount of the vehicle on the basis of a wheel speed variation detected by the wheel speed sensor, a state amount calculating unit that calculates the state amount of the vehicle by inputting the basic input amount to a vehicle model representing the motion of the vehicle, and a damper controlling unit that controls the damping force of a damping-force-variable damper on the basis of the calculated state amount. If the wheel speed variation detected by the wheel speed sensor decreases below zero by a predetermined value or more on the minus side, the vertical load of the wheel is considered to be decreased, and the damping force is controlled to be greater than before the decrease.
