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: 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: Hydraulic systems and methods comprising a source of hydraulic pressure; a hydraulic load; and an energy recovery circuit. The source of hydraulic pressure is fluidly connected to the hydraulic load through a first hydraulic channel with an orifice. The energy recovery circuit includes a recovery channel which is fluidly connected at its first end to the orifice on the side of it which is connected to the source of hydraulic pressure, and which is fluidly connected at its second end to a hydraulic motor.

Abstract: A method for controlling the ground grip of a wheeled loader having a pair of front wheels, a bucket, and at least one boom, comprising measuring the relative position of said front wheels with respect to the ground, detecting the reaching of a critical threshold value by measuring the relative position of the front wheels with respect to the ground, comparing the measurement of the relative position of the front wheels to a critical threshold value, and, when the measurement of the relative position of the front wheels with respect to the ground reaches the critical threshold value, inhibiting a further tilting of the bucket and a further lowering of the at least one boom.

Abstract: The present disclosure relates to a valve assembly, in particular for use in a tire inflation system, the valve assembly comprising: a valve body comprising 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, wherein when the piston is in the open position the first fluid port is fluidly connected with the second fluid port, and wherein when the piston is in the closed position the first fluid port is fluidly isolated from the second fluid port, wherein 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. The present disclosure further relates to a tire inflation system including said valve assembly.
