Abstract
In a suspension control system for a suspension supporting a mass body on a support base via a parallel combination of a spring means variable damp coefficient, absolute displacement (Z) and absolute having a variable spring coefficient and a shock absorber having a velocity (Z) of the mass body along a moving path of expansion and contraction of the spring means and the shock absorber, and relative displacement (Y) and relative velocity (Y) of the mass body in reference to the support base along the moving path are respectively obtained, and the damp coefficient of the shock absorber is controlled according to the ratio of the absolute velocity to the relative velocity (Z/Y) so as to be substantially proportional thereto, while the spring coefficient of the spring means is controlled according to the ratio of the absolute displacement to the relative displacement (Z/Y) so as to be substantially proportional thereto.
