Abstract: A damper system for a vehicle comprises an electrically adjustable hydraulic shock absorber and a damper control module. The damper control module is disposed with and coupled to with the shock absorber. The damper control module determines a target damping state of the shock absorber based on data received from a plurality of sensors. Furthermore, the damper control module controls the shock absorber, such that the shock absorber operates at the target damping state.

Abstract: A damper system for a vehicle includes a shock absorber and a damper module. The shock absorber includes a plurality of digital valves. The shock absorber is operable at one of multiple damping states based on a valve state of the digital valves. The damper module is coupled to each of the digital valves and controls each of the digital valves to a desired state based on a damper setting. The damper module determines a target damping state, where the target state is one of the multiple damping states. The damper module performs a switch operation to control the valve state of the plurality of digital valves to a given desired state when the target damping state is different from a present damping state.

Abstract: A damper system for a vehicle comprises an electrically adjustable hydraulic shock absorber and a printed circuit board assembly. The printed circuit board assembly includes power drive electronics, and is electrically coupled to the shock absorber. The printed circuit board assembly is disposed with the shock absorber.

Abstract: A shock absorber has a compression valve assembly that provides a high damping load during a compression stroke and an extension valve assembly that provides a high damping load during an extension stroke. One or more digital valve assemblies is positioned to work in parallel with the compression valve assembly and the extension valve assembly to provide a lower damping load. The lowering of the damping load is based upon the cross sectional area of flow passages provided by the one or more digital valve assemblies.

Abstract: A shock absorber includes a pressure sensitive valve assembly that controls fluid flow through the pressure sensitive valve assembly based upon the velocity of the piston assembly in the shock absorber. The pressure sensitive valve assembly restricts fluid flow as the velocity of the piston in a compression stroke increases to increase the damping loads provided by the shock absorber.

Abstract: A two-stage shock absorber has a pressure tube within which a valve assembly is slidably disposed. A piston rod is attached to the valve assembly and extends out of the pressure tube. A ring is slidably disposed within the pressure tube and engages the valve assembly. After a specified amount of movement of the valve assembly with respect to the pressure tube in an extension movement of the shock absorber, the sleeve engages a metered slot and reduces the fluid flow through the valve assembly to progressively switch the shock absorber from soft damping to firm damping.

Abstract: A shock absorber has a base valve assembly which includes a compression valve assembly and an acceleration valve assembly. The compression valve assembly controls a fluid path through the base assembly to provide a firm damping characteristic for the shock absorber during low acceleration movement. The acceleration valve assembly controls a second fluid path through the base assembly to provide a soft damping characteristic for the shock when the shock absorber experiences acceleration beyond a specified amount.
