Abstract

The present invention provides an improved method and apparatus for controlling and making real-time adjustments to damping in a shock absorber based on driving conditions and desired driving characteristics. The shock absorber has a reservoir compartment and a fluid-filled internal chamber divided into a compression compartment and a rebound compartment by a movable piston. A piston rod is connected to the piston and extends through a seal in the rebound end of the internal chamber. The shock absorber contains flow passages connecting, and normally allowing fluid to flow between, the reservoir compartment, the compression compartment and the rebound compartment. Fluid flow in the flow passages, which is directly related to the relative motion between the shock main body and the piston rod assembly, is controlled by providing a variable valve closing force. Control of the valve closing force, and thus the damping of the shock absorber, may be controlled in real-time either by the vehicle operator or an autonomous damping, control system.
