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: A motion sickness control system for a vehicle includes a vibrator. The motion sickness control system includes a sensor configured to measure vibration of the vehicle. The motion sickness control system includes a computer having a processor and a memory storing instructions executable by the processor to actuate the vibrator at a target frequency based on the measured vibration of the vehicle. The target frequency attenuates the measured vibration of the vehicle.

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 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: 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.

Abstract: A system for performing ride control blending in an electric vehicle may include a control distribution module, a torque control module, and a vertical force control module. The control distribution module may calculate a torque control demand and a vertical force control demand associated with a wheel of the vehicle based on a generalized vertical force, a pitch moment, and a roll moment associated with a body of the vehicle. The torque control module may adjust torque applied by an electric motor to the wheel based on the torque control demand. The vertical force control module may adjust vertical force applied by a suspension actuator to the wheel based on the vertical force control demand.

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.
