Abstract: A suspension control system including a suspension control unit, an unsprung mass accelerometer positioned at each wheel of the vehicle, and a global positioning system. The suspension control unit determines if a road irregularity, such as a bump or pothole, is approaching based on vehicle location data, provides pre-emptive road event classification information for the approaching road irregularity, and sets both a threshold based suspension pre-setting and a threshold based pre-trigger based on the pre-emptive road event classification information. The suspension control unit monitors the unsprung mass acceleration data, calculates a slope value for the unsprung mass acceleration data, and activates a suspension control action if the unsprung mass acceleration data exceeds the threshold based pre-trigger and the slope value exceeds a maximum slope value.

Abstract: An air-spring assembly includes a flexible bellows extending from a top end to a bottom end and enclosing an air-spring chamber between the top end and the bottom end, a first panel partially defining the air-spring chamber and movable in response to a pressure of the air-spring chamber, an enclosure partially defining a working chamber fluidly isolated from the air-spring chamber, a second panel partially defining the working chamber and movable relative to the enclosure, and a linkage member fixed relative to the first panel and to the second panel and defining a fixed distance between the first panel and the second panel. The top and bottom ends are fixable to a frame and a wheel of a vehicle, respectively. A volume of the air-spring chamber varies with movement of the bottom end relative to the top end. Movement of the second panel changes a volume of the working chamber.

Abstract: A suspension system including four dampers is disclosed where each damper includes a compression chamber and a rebound chamber. First and second hydraulic circuits interconnect the compression and rebound chambers of the front left and back right dampers, while third and fourth hydraulic circuits interconnect the compression and rebound chambers of the front right and back left dampers. A first bi-directional pump is connected between the first and second hydraulic circuits and a second bi-directional pump is connected between the third and fourth hydraulic circuits. The first and second bi-directional pumps can either pump in the same direction or in opposite directions. The level of pitch and roll stiffness can be adjusted by running the first and second bi-directional pumps to change the pressure in select hydraulic circuits of the system.

Abstract: A suspension system including four dampers each having a compression chamber and a rebound chamber. First and second hydraulic circuits interconnect the compression and rebound chambers of the front dampers, while third and fourth hydraulic circuits interconnect the compression and rebound chambers of the back dampers. A first longitudinal hydraulic line extends between and connects the first and third hydraulic circuits and a second longitudinal hydraulic line extends between and connects the second and fourth hydraulic circuits. A first bi-directional pump is connected in-line with a fluid distribution line that extends between and connects the first and second longitudinal hydraulic lines a can pump fluid in opposite directions through the fluid distribution line to provide active roll stiffness.

Abstract: A single axle suspension system that includes right and left dampers, first and second hydraulic circuits, a first pressurizing mechanism that is connected in fluid communication with the first hydraulic circuit, and a second pressurizing mechanism that is connected in fluid communication with the second hydraulic circuit. The first and second pressurizing mechanisms are configured to provide active roll control by adding and removing hydraulic fluid to and from the first and second hydraulic circuits to increase and decrease pressure inside the first and second hydraulic circuits independent of damper movements. This in turn causes a simultaneous increase in the fluid pressure inside either the first working chamber of the right and the second working chamber of the left damper or the first working chamber of the left damper and the second working chambers of the right damper to provide roll stiffness that counters vehicle roll during cornering.
