Abstract: Methods and systems for hydraulic vehicle suspension are provided. A hydraulic suspension system, in one example, includes a first manifold including a piston-side interface and a rod-side interface fluidically coupled to a piston chamber and a rod chamber, respectively, for each of a first hydraulic cylinder and a second hydraulic cylinder. In the system, the first manifold includes a first electrically activated valve fluidically coupled to the piston-side interfaces, a first damping device, and a second damping device, the first electrically activated valve is configured to lock and unlock vertical motion of the first and second hydraulic cylinders and, while vertical motion of the first and second hydraulic cylinders is locked, the first electrically activated valve permits fluidic communication between the first and second hydraulic cylinders to permit free roll motion in the hydraulic suspension system.

Abstract: Methods and systems for vehicle suspension are provided. A leveling manifold includes, in one example, a plurality of electrically-activated valves arranged between, on a first end, a rod-side and a piston-side of one or more hydraulic cylinders, and on a second end, a pressure source and a tank, wherein the plurality of electrically-activated valves include a first valve, a second valve, a third valve, and a fourth valve. The leveling manifold further includes a first flow path extending through the first and second valves and from the rod-side to the second end and a second flow path extending through the third and fourth valves and from the piston-side to the second end, the leveling manifold is designed to manage operation of the first, second, third, and/or fourth valves to independently adjust a position and a stiffness of the one or more hydraulic cylinders.

Abstract: The disclosure concerns an electronic control unit for a hydraulic system, the hydraulic system comprising a pump drivingly coupled to a motor, the pump configured to provide a supply pressure in a supply line of the hydraulic system. The electronic control unit is configured to receive a load sensing signal corresponding to a sensed load measure of the hydraulic system; determine, based on the load sensing signal and a predetermined pump margin, a target torque parameter for the motor; and adjust the motor based on the target torque parameter. The disclosure further concerns a hydraulic system and a method for controlling a hydraulic system.

Abstract: A valve assembly for use in a tire inflation system, the valve assembly including: a valve body including a first fluid port and a second fluid port; a piston disposed at least partially within the valve body and configured to be moved relative to the valve body between an open position and a closed position. When the piston is in the open position, the first fluid port is fluidly connected with the second fluid port. When the piston is in the closed position, the first fluid port is fluidly isolated from the second fluid port. When the piston is in the open position, the first fluid port and the second fluid port are fluidly connected with one another via a fluid channel extending through the piston. A tire inflation system including the valve assembly.

Abstract: The present document relates to a control device for a central tire inflation system, comprising: an inlet for connection with a pressure source, at least a first outlet for connection with a first pneumatic tire, a supply valve, at least a first channel valve, and at least a first pressure-limiting valve, wherein the supply valve and the first channel valve selectively fluidly connect the inlet to the first outlet and are fluidly connected in series between the inlet and the first outlet, and wherein the first pressure-limiting valve is fluidly connected to the first outlet for limiting a pressure at the first outlet. The present document further relates to methods of operating the control device for the central tire inflation system.
