PROBLEM TO BE SOLVED: To provide a suspension control device which a vehicle body posture can be made adequate even if the vehicle behavior is made unstable and violence below springs can be prevented without fitting a vertical G sensor and a stroke sensor.SOLUTION: A suspension control device comprises: basic input quantity calculation means (37) which calculates a basic input quantity (u) of a vehicle based on wheel speed variation quantity &Dgr;Vw detected by wheel speed sensors 9; sky hook control means (90) which controls attenuation force of a damper 6 based on the basic input quantity; and road surface convexo-concave judgment means (23) which judges road surface convexo-concave. The sky hook control means (90), in a case that the road surface convexo-concave is judged, implements, for a specified continuation time (TB), increasing processing which increases the attenuation force (sky hook control target current Ash) of the damper 6 compared with the value immediately before the road surface convexo-concave is judged against at least wheels in which the road surface convexo-concave is judged. |
