Abstract: A system for controlling a suspension of a vehicle includes a plurality of sensors, an anti-roll moment module configured to determine a front-to-total anti-roll moment distribution based on at least a first operating parameter of the vehicle, at least one suspension actuator, and a suspension control module configured to control the at least one suspension actuator based on the determined front-to-total anti-roll moment distribution. A method of producing an anti-roll moment distribution module for a vehicle includes determining understeer characteristics of the vehicle, determining a maximum lateral acceleration of the vehicle, adjusting the understeer characteristics based on the determined maximum lateral acceleration, determining reference understeer characteristics, determining a plurality of reference yaw rates and a plurality of feedforward contributions using a non-linear quasi-static model of the vehicle, storing the reference yaw rates in a first look-up table, and storing the feedforward contributions in a second look-up table.

Abstract: A method of producing an anti-roll moment distribution module for a vehicle comprises determining understeer characteristics of the vehicle, determining a maximum lateral acceleration of the vehicle, adjusting understeer characteristics of the vehicle based on the maximum lateral acceleration, determining reference understeer characteristics, determining a plurality of reference yaw rates based on (i) the maximum lateral acceleration and (ii) the reference understeer characteristics using a non-linear quasi static vehicle model, storing the plurality of reference yaw rates in a first look up table in the anti-roll moment distribution module, determining a plurality of feedforward contributions using the non-linear quasi static model of the vehicle. Each feedforward contribution of the plurality of feedforward contributions can be used to determine a front to total anti-roll moment distribution for the vehicle. The plurality of feedforward contributions are stored in a second look up table in the anti-roll moment distribution module.

Abstract: A damper system for a vehicle is provided that includes an outer tube, a piston rod, and a piston assembly that is mounted to the piston rod and separates the outer tube into first and second working chambers. A valve assembly, mounted to the piston assembly, controls fluid flow between the first and second working chambers. A magnetic rotor is fixed to and extends annularly about the outer tube. A stator assembly is coupled to the piston rod by a spherical bearing assembly. The stator assembly includes a plurality of coils that apply an active damping force to the piston rod when energized. The coils can also generate electricity from axial movements of the piston rod relative to the outer tube. One or more glide bearings are disposed radially between the coils and the magnetic rotor in a sliding fit to stabilize the stator assembly.

Abstract: A damper system for a vehicle is provided that includes a pressurized gas damper, electromagnetic actuator, and pressurized gas spring. The pressurized gas damper includes first and second working chambers that are fluidly connected by a flow control orifice. The electromagnetic actuator includes a stator assembly with a stator cavity and a magnetic rotor that is slidingly received in the stator cavity. The magnetic rotor is fixed to a damper tube that houses the second working chamber. The stator cavity and an end of the damper tube cooperate to define the first working chamber. The pressurized gas spring includes a bellows chamber that extends annularly about the damper tube. The damper tube includes an opening between the second working chamber and the bellows chamber.

Abstract: The active suspension system includes right and left dampers, a pump, and a control valve system. Each of the right and left dampers includes a damper housing, a piston rod, and a piston that is mounted on the piston rod. The piston is arranged in sliding engagement inside the damper housing such that the piston divides the damper housing into first and second working chambers. The pump includes a pump intake and a pump outlet. The control valve system is connected in fluid communication with the first and second working chambers of the right damper, the first and second working chambers of the left damper, the pump intake, and the pump outlet. The control valve system has several different arrangements of fluid flow paths that provide different working modes for the active suspension system.

Abstract: A vehicle chassis control system may include a target calculation module, brake control module, suspension control module, and tire pressure control module. The target calculation module calculates a target brake torque, a target vertical force, and a target tire pressure associated with the wheel of a vehicle. The brake control module adjusts brake torque applied to the wheel based on a comparison of the target brake torque and an estimated current brake torque. The suspension control module adjusts vertical force applied to the wheel based on a comparison of the target vertical force and an estimated current vertical force. The tire pressure control module adjusts tire pressure in the wheel based on a comparison of the target tire pressure and a measured tire pressure.

Abstract: A damper system for a vehicle is provided that includes a damper and actuator. The damper extends longitudinally along a damper axis between first and second damper ends. The actuator is separate and spaced apart from the damper. The actuator extends longitudinally along an actuator axis between first and second actuator ends. The damper and the actuator are arranged next to one another where the actuator axis is spaced from and substantially parallel to the damper axis. The damper and the actuator are positioned within a cylindrical packaging envelope that has a diameter of 300 millimeters or less. The cylindrical packaging envelope is an imaginary cylinder, which may be defined by one or more components of a vehicle's suspension system such as a coil spring or an upper suspension arm. The damper and the actuator are completely contained within the cylindrical packaging envelope.

Abstract: The present disclosure relates to an electromagnetic rotary shock absorber for damping a wheel suspension component associated with a motor vehicle. The electromagnetic rotary shock absorber has a flywheel and at least one damper. The damper has a first element operably associated with the flywheel for driving the flywheel rotationally, and a second element operably associated with the wheel suspension component. The damper operates to dampen relative movement of the wheel suspension component using an inertia of the flywheel.
