Abstract
A suspension system for a vehicle, includes (a) a shock absorber disposed between a sprung portion and an unsprung portion and having a damping-force changing mechanism, the shock absorber being configured to generate a damping force with respect to a relative movement of the sprung portion and the unsprung portion such that the magnitude of the damping force is changeable, and (b) a controller configured to control the damping-force changing mechanism. The controller includes a target sprung-speed determining portion configured to determine, as a target sprung speed, a speed of the sprung portion in a behavior of a body of the vehicle that matches an operation input to the vehicle by a driver, for permitting the behavior to match the operation input, the controller being configured to control the damping force such that the speed of the sprung portion becomes equal to the target sprung speed.
