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 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 control system and method is disclosed for controlling an active suspension and a leveling system for a motor vehicle. The control system may use estimator, controller and management modules. The estimator module processes measured signals obtained from various components and sensors of the vehicle relating to modal displacements, velocities and accelerations, and calculates derived signals which are used as inputs to the controller module. The controller module calculates the desired damper force for each active damper based on motions of the vehicle body and wheels. The management module translates the desired active damper force into an appropriate set of control signals to control each active damper. These operations are performed for each active damper of the vehicle to control each damper in real time.

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 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 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.
