Abstract:
A suspension control system comprising:a shock absorber of a variable damping characteristic type to be interposed between sprung and unsprung members of a vehicle; an actuator for changing damping characteristics of said shock absorber; a velocity detecting device for detecting velocity of said sprung member; a piston speed estimating device for estimating a level of piston speed of a piston performing sliding movement inside said shock absorber; and a controller having damping force maps for showing relationships between damping force and an actuator command signal, respectively, in correspondence to various levels of the piston speed; wherein said controller is to obtain necessary damping force from the velocity of the sprung member, and further, said controller is to select a damping force map, from said damping force maps, corresponding to the level of piston speed estimated by said piston speed estimating device and is to output the actuator command signal on the basis of the selected damping force map.
