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 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 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 vehicle suspension system that includes a cylinder (22), a rod (24) inserted within the cylinder, a piston (26) coupled to the rod and a piston valve (27) which has an input piston current. The suspension system further includes a base coupled to the cylinder, a base valve which (29) has an input base current, and a controller (33) coupled to the piston valve and the base valve. The controller is adapted to generate the input piston current and the input base current based on a generated virtual current.

Abstract: A method for controlling a shock absorber system of a vehicle that includes a plurality of controlled shock absorbers (20) linearizes the system. The method includes transforming original control inputs of the shock absorbers into virtual damper force input signals based on a bilinear damper characteristic. The system dynamics are then decoupled into modal components using static decoupling matrices, and the system is controlled with a linear decentralized controller.
