Abstract

See full text

A suspension control apparatus includes a damping force adjustable shock absorber disposed between a vehicle body and a wheel of a vehicle and capable of adjusting a damping force to be generated, a vertical movement detection device configured to detect a state regarding a vertical movement of a vehicle, and a controller including: a target damping force calculation section configured to calculate a target damping force based on a detection result of the vertical movement detection device, a correction section configured to calculate a corrected damping force, which is acquired by reducing the target damping force when a relative speed is a low speed between a sprung side and an unsprung side of the damping force adjustable shock absorber, and a control signal output section configured to output the control signal corresponding to the corrected damping force to the damping force adjustable shock absorber.
