    Abstract: A process for correcting longitudinal roll from an offset load using active roll control within a vehicle is provided. The process includes, within a computerized controller using axle-based control to control a suspension system, operating programming to control pneumatic pressure supplied to each of a plurality of air spring devices within the suspension system to execute a vehicle leveling event including one of adjusting a height of the vehicle or maintaining the height of the vehicle. The process further includes operating programming to, simultaneously with the controlling the pneumatic pressure, utilize a plurality of active sway bars to provide an offset torque to the vehicle body. Each of the plurality of active sway bars is associated with one of a plurality of axles. Providing the offset torque is based upon a number of moles of air in each of the plurality of air spring devices and reducing the longitudinal roll.

    Abstract: An exemplary self-balancing air spring includes a first chamber, the first chamber defining a primary volume, the first chamber including a movable piston, a second chamber fluidicly coupled to the first chamber via a first orifice and a second orifice, the second chamber defining a secondary volume, and an actuator coupled to the movable piston. In some aspects, the first orifice is an electromechanical valve and the second orifice is a bleed valve that equalizes the pressure between the first and second chambers.

    Abstract: An exemplary energy delivery system includes a housing. The housing includes a linear motor including a translational member and an electromagnetic field generating member. Energization of the electromagnetic field generating member induces translation of the translational member along a longitudinal axis of the linear motor. The housing further includes a first cylinder including a first chamber and a movable first piston and a second cylinder including a second chamber and a movable second piston. The first and second cylinders are coupled in-line with the linear motor within the housing and translation of the translational member along the longitudinal axis translates the first piston within the first chamber in a first direction and translates the second piston within the second chamber in a second direction opposite the first direction.

    Abstract: A vehicle suspension control system includes a central suspension spring core, a first suspension spring surrounding an upper portion of the central suspension spring core, a second suspension spring surrounding a lower portion of the central suspension spring core, the first suspension spring and the second suspension spring coupled between a wheel and a fixed structure of a vehicle to inhibit movement of the wheel, a spring seat surrounding the central suspension spring core and coupled between the first and second suspension springs, the spring seat including an outer sleeve and multiple seals for retaining magnetorheological fluid between the outer sleeve and the central suspension spring core, one or more electromagnets adjacent the spring seat, and a suspension control module configured to energize the one or more electromagnets to selectively modify a viscosity of the magnetorheological fluid to inhibit movement of the first suspension spring or the second suspension spring.
