摘要：
A suspension system of a vehicle for calculating a product of the absolute speed zs of the sprung member and the relative speed zs-zu between the sprung member and the unsprung member and for controlling the damping force characteristic of the shock absorber to be higher if that product is more than the predetermined value and to be lower if the product is less than that value. An insensible range is formed for restricting switching of the damping force characteristic when .vertline.zs.vertline. and .vertline.zs-zu.vertline. are less than the predetermined value .delta.z, .delta.r, so that the damping force characteristic of the shock absorber is kept lower if .vertline.zs.vertline.>.delta.z and .vertline.zs-zu.vertline. or .vertline.zs-zu.vertline. .delta.z and .vertline.zs-zu.vertline. or .vertline.zs-zu.vertline.
