A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

A vehicle damper assembly is disclosed. The damper includes a reservoir, a cylinder having an inner diameter (ID) and fluidly coupled with the reservoir and a rod and a piston. The piston coupled to the rod and configured to divide the cylinder into a compression side and a rebound side. The damper further includes an active base valve to provide independent flow control for a reservoir flow path between the cylinder and the reservoir. The damper also includes an active main valve to provide independent flow control for a piston flow path fluidly coupling the compression side with the rebound side.

Disclosed herein is a sway bar system comprising a damping link that couples a first end of a sway bar to a first location on a vehicle. The damping link is comprised of a body comprising a damping chamber and a reservoir. There is also a through shaft coupled to a piston, where the piston divides the chamber into a first chamber and a second chamber. A high-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the first chamber and the second chamber to the reservoir. A low-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the reservoir to the first chamber and the second chamber. The high-pressure line and the low-pressure line assist in self-centering the sway bar.

The invention relates to a vehicle seat or a vehicle cab with a suspension system comprising an upper closing part and a lower closing part which is deflectable in relation to the upper closing part, which closing parts are connected to each other in a resilient manner by means of a suspension element, and with a damping system for damping vibrations acting on at least one of the two closing parts, wherein the damping system and a distance levelling system for adjusting a distance between the upper closing part and the lower closing part have a common fluid actuator element controlled by compression and tension stages.

The invention relates to a shock absorber (1), in particular for a motor vehicle, which comprises: a cylinder (2) containing a hydraulic fluid; a main piston (4) actuated by a rod (3), defining in the cylinder a first main chamber (5) and a second main chamber (6), the second main chamber containing the rod; a hydraulic fluid vessel (24); and a valve (11) placed in the flow of the hydraulic fluid between the first main chamber and the second main chamber or between the first main chamber and the vessel. The valve comprises a mobile gate (14) engaging with a seat (13), a spring (20) tending to urge the gate against the seat thereof, and a mobile valve piston (17, 78), defining a first valve chamber (18, 82) and a second valve chamber (19, 83) in the valve, said mobile valve piston being capable of compressing the spring and closing the gate. The shock absorber also includes a control restriction (15) mounted in the flow of the hydraulic fluid from the first main chamber (5) during a compression movement, the control restriction being capable of generating a pressure difference acting on the respective surfaces of the mobile valve piston in a direction that tends to compress the spring during a compression movement and a means (51) for slowing the movement of the mobile valve piston (17, 78).
