Disclosed herein is a sway bar system comprising a damping link that couples a first end of a sway bar to a first location on a vehicle. The damping link is comprised of a body comprising a damping chamber and a reservoir. There is also a through shaft coupled to a piston, where the piston divides the chamber into a first chamber and a second chamber. A high-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the first chamber and the second chamber to the reservoir. A low-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the reservoir to the first chamber and the second chamber. The high-pressure line and the low-pressure line assist in self-centering the sway bar.

A vehicle reinforcing member includes first and second pistons movable in an axial direction in a cylinder. An inside of the cylinder is sectioned into a gas chamber and a main liquid chamber by the first piston, and the main liquid chamber is sectioned into a first sub-liquid chamber and a second sub-liquid chamber by the second piston. Gas is sealed in the gas chamber, and liquid is sealed in the first and second sub-liquid chambers. A piston rod is coupled to the second piston. The cylinder and the piston rod are respectively coupled to two locations of a vehicle body. A communication path connects the first sub-liquid chamber to the second sub-liquid chamber. A moving amount of the liquid in the communication path is adjusted by an adjuster such that a moving load through the second piston is adjusted.

A damping system of a two-track vehicle includes a passive stabilizer having a torsion bar which runs in a vehicle transverse direction and having lever elements which adjoin the torsion bar at the end sides and which are connected to mutually oppositely situated wheel suspension arrangements of an axle of the vehicle. Two actuators are assigned to respective wheels of the wheel suspension arrangements and are mounted on the vehicle body. Each actuator has a drive by way of which a torque can be exerted on that section of the stabilizer which faces toward the respective wheel. Here, the actuators are in the form of electric motors and are designed to dampen vertical vibrations of the respective wheel or of the so-called unsprung mass, and/or vibrations of the vehicle body in a frequency range between 0 Hertz and at least 20 Hertz, through suitable regulation of the drive of the actuators and thus also through active introduction of forces into the system.

Anti-roll systems and related methods are disclosed. An example anti-roll system includes a first stabilizer bar having a first end to operatively couple to a first wheel assembly of a vehicle and a second stabilizer bar having a first end to operatively couple to a second wheel assembly of the vehicle. A rotary damper is to couple a second end of the first stabilizer bar and a second end of the second stabilizer bar. A damping characteristic of the rotary damper is to vary based on a driving condition of the vehicle.

A sway bar system is described. The sway bar system includes a sway bar having a first end and a second end. The sway bar system further includes a first electronically controlled damper link which is coupled to the first end of the sway bar. The first electronically controlled damper link is configured to be coupled a first location of a vehicle. The sway bar system also has a second link which is coupled to the second end of the sway bar. The second link is configured to be coupled a second location of the vehicle.

A tensioning device for attachment to a vehicle suspension system reduces play at ends of a pan hard bar (track bar) of the vehicle suspension system, remedying instabilities that can occur in vehicle suspensions. The device can include a bracket clamped to the pan hard bar at a point between the ends of the pan hard bar, or may be otherwise mounted to a bracket formed on the pan hard bar in OEM installations. The other end of the device is secured to the frame or the axle of the vehicle, generally near an end of the pan hard bar. The device is pre-tensioned to apply force at the ends of the pan hard bar, and includes a damping plunger to also damp forces that vibrate the ends of the pan hard bar, further loosening attachments. The tension is field-adjustable and may be tuned for various applications.

Anti-roll systems and related methods are disclosed. An example anti-roll system includes a first stabilizer bar having a first end to operatively couple to a first wheel assembly of a vehicle and a second stabilizer bar having a first end to operatively couple to a second wheel assembly of the vehicle. A rotary damper is to couple a second end of the first stabilizer bar and a second end of the second stabilizer bar. A damping characteristic of the rotary damper is to vary based on a driving condition of the vehicle.

A stabilizer includes a stabilizer bar, left and right cylinders, a parallel pipe, a cross pipe, a parallel on-off valve, and a valve controller. The parallel on-off valve maintains communication between a left side first fluid room of the left cylinder and a right side first fluid room of the right cylinder and maintains communication between a left side second fluid room of the left cylinder and a right side second fluid room of the right cylinder by opening itself. The parallel on-off valve cuts off the communication by closing itself. The valve controller switches an opening/closing state of the parallel on-off valve based on a running state of a vehicle or an operation state of the vehicle by a driver.

Aspects relate to systems and methods for pre-emptively managing suspension loads. A control system (100, 200) is configured to receive a driving surface signal (165) indicative of a property of a driving surface ahead of the vehicle (600). The control system is further configured to determine, in dependence on the received driving surface signal and on a current vehicle operational state, an attribute parameter. The attribute parameter, when provided to an actuator (318a, 318b . . . 318z) of the suspension system, causes the actuator to act to control a suspension force acting on the suspension system due to a movement of the vehicle along the driving surface to be below a predetermined suspension force value. The control system is further configured to output an actuator control signal (155) to the actuator of the suspension system to control the actuator in dependence on the determined attribute parameter.

Disclosed is an automatic vehicle suspension tuning system. The system has a control module to receive user input, an ECU with a processor and a memory, one or more road condition sensors, and one or more controllable suspension system components. The ECU controls the adjustments of the controllable suspension system component in response to user input to the control module as well as input from the road condition sensors during operation of the vehicle. A method of tuning a controllable suspension system component is also disclosed.
