Suspension control apparatus for damping oscillation of a vehicle

A suspension control apparatus comprising:

• a damping force adjustable shock absorber disposed between a sprung side and an unsprung side 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 the vehicle;
• and
• a controller configured to output a control signal for controlling the damping force to be generated by the damping force adjustable shock absorber based on a detection result of the vertical movement detection device,
• wherein the controller is configured to:
• calculate a target damping force based on a detection result of the vertical movement detection device,
• calculate a corrected damping force which is smaller than an absolute value of the target damping force in a low-speed region in which a relative speed between the sprung side and the unsprung side of the vehicle is a low speed, an absolute value of the corrected damping force being set so that the corrected damping force increases as the relative speed increases and that an inclination of the corrected damping force to the relative speed when the relative speed is in a first range of the low-speed region is smaller than the inclination of the corrected damping force to the relative speed when the relative speed is in a second range of the low speed region in which the relative speed is higher than in the first range, and
• output the control signal corresponding to the corrected damping force to the damping force adjustable shock absorber.
