<p>A suspension system (10) including: (a) a suspension spring (51); (b) a shock absorber (52); and (c) a displacement force generator (20) operable to generate a displacement force forcing sprung and unsprung members of a vehicle to be displaced toward or away from each other. The displacement force generator includes (c-1) an elastic body (22) connected one of the sprung and unsprung members and (c-2) an actuator (26) disposed between the elastic body and the other of the sprung and unsprung members and interconnecting the elastic body and the other of the sprung and unsprung members. The actuator includes a motor (70), and is operable to generate an actuator force based on a motor force generated by the motor, such that the generated actuator force acts on the elastic body and such that the generated actuator force is transmitted to the sprung and unsprung members via the elastic body so as to act as the displacement force. The suspension system further includes (d) a displacement force controller (100) operable to control operation of the motor so as to control the displacement force. The displacement force controller performs a damping-force control for controlling the displacement force as a damping force for damping vibration of the spring member and/or the unsprung members.</p> |
