Abstract: A system for grading filling of a suspension system includes: a pump control module configured to, during first and second periods, operate an electric pump of the suspension system in first and second directions and decreasing and increasing hydraulic fluid pressure within the suspension system, respectively; a monitoring module configured to: store a first pressure of hydraulic fluid within the suspension system measured using a pressure sensor when the first pressure is less than or equal a first predetermined pressure while the pump is operated in the first direction; and store a second pressure measured using the pressure sensor when the second pressure is greater than or equal a second predetermined pressure while the pump is operated in the second direction; and a grade module configured to determine a grade value for the filling of the suspension system based on the first and second pressures.

Abstract: A suspension system including hydraulic circuits that extend between dampers located at opposite corners of the vehicle and at least one load distribution unit that is connected in fluid communication with at least two hydraulic circuits. The load distribution unit includes a manifold block with a cylinder bore, a pair of pressure tubes, a piston rod assembly, and a pair of reserve tubes. The pressure tubes are partially received in the cylinder bore to define a pair of opposed cylinders. The piston rod assembly includes a piston rod and a pair of opposed pistons that are slidingly received within the opposed cylinders. The reserve tubes are at least partially received in the cylinder bore and are arranged annularly about the pressure tubes to define a first pair of reservoir chambers between the pressure tubes and the reserve tubes.

Abstract: A suspension system including hydraulic circuits that extend between dampers located at opposite corners of the vehicle and at least one load distribution unit that is connected in fluid communication with at least two hydraulic circuits. The load distribution unit includes a manifold block with a cylinder bore, a pair of pressure tubes, a piston rod assembly, and an integral rod guide and pressure tube coupler. The pressure tubes are partially received in the cylinder bore to define a pair of opposed cylinders and mate with the integral rod guide and pressure tube coupler. The piston rod assembly includes a piston rod and a pair of opposed pistons that are slidingly received within the opposed cylinders. In addition to retaining the pressure tubes, the integral rod guide and pressure tube coupler supports and permits the piston rod to slide longitudinally relative to the manifold block.

Abstract: A suspension system and associated control methods that reduce temperature related fluctuations in the internal pressures and stiffness of the suspension system. A manifold assembly is connected in fluid communication with a plurality of dampers via hydraulic circuits and a pump assembly via a pump hydraulic line. Onboard sensors generate real-time data regarding the vehicle. A suspension control unit, arranged in electronic communication with the aforementioned components, monitors the real-time data, sets a target stiffness and a target pressure, calculates an effective stiffness based on the real-time data, determines if the effective stiffness is above or below the target stiffness and sets a new target pressure accordingly by making stepwise decreases or increases until the new target pressure is reached.

Abstract: A suspension system including four dampers is disclosed where each damper includes a compression chamber and a rebound chamber. A first hydraulic circuit includes a front hydraulic line, a rear hydraulic line, and a first longitudinal hydraulic line that extends between and fluidly connects the front and rear hydraulic lines of the first hydraulic circuit. A second hydraulic circuit includes a front hydraulic line, a rear hydraulic line, and a second longitudinal hydraulic line that extends between and fluidly connects the front and rear hydraulic lines of the second hydraulic circuit. First and second longitudinal comfort valves are positioned in the first and second longitudinal hydraulic lines, respectively, between the front and rear hydraulic lines. Both of the first and second longitudinal comfort valves are electromechanical valves and can be actuated to couple and decouple front axle roll control from rear axle roll control.

Abstract: A suspension system including four dampers where each damper includes compression and rebound chambers. The suspension system has four hydraulic circuits, each including a cross-over hydraulic line that extends between dampers located at opposite corners of the vehicle (i.e., between the front left and back right dampers or between the front right and back left dampers). The suspension system further includes four electromechanical comfort valves that open and close four bridge hydraulic lines that extend between the cross-over hydraulic lines at each corner of the vehicle. Each cross-over hydraulic line is connected to a manifold assembly by a corresponding manifold hydraulic line. The manifold assembly includes four manifold valves that are connected to a pump assembly and two manifold comfort valves. All six comfort valves are electromechanical valves that can be actuated to control the roll and pitch of the vehicle during cornering, braking, and acceleration.
