A roll vibration damping control system includes an electronic control unit configured to: compute a sum of a product of a roll moment of inertia and a roll angular acceleration of a vehicle body, a product of a roll damping coefficient and a first-order integral of the roll angular acceleration, and a product of an equivalent roll stiffness of the vehicle and a second-order integral of the roll angular acceleration, as a controlled roll moment to be applied to the vehicle body; compute a roll moment around a center of gravity of a sprung mass as a correction roll moment, the roll moment being generated by lateral force on wheels due to roll motion; and compute a target roll moment based on a value obtained by correcting the controlled roll moment with the correction roll moment.

Provided are a vehicle control apparatus and a vehicle control method, including: a sensor configured to sense a vehicle speed value, operation information of an actuator for generating a torque in a stabilizer bar of an active roller stabilizer (ARS), and operation information of the stabilizer bar; and a controller configured to calculate a target torque value that is to be generated in the stabilizer bar on the basis of the sensed vehicle speed value, the sensed operation information of the actuator, and the sensed operation information of the stabilizer bar, and to determine whether the sensed vehicle speed value is a target vehicle speed value that is set to perform an ARS control mode, and in response to the sensed vehicle speed value determined to be the target vehicle speed value, and determine a deadband period in which a torque of the actuator is not transmitted, using a change value of a torque value and a change state of the torque value while the torque value is tracing the calculated target torque value.

A method for operating a motor vehicle with a chassis arrangement having at least two vibration dampers. A body control is carried out at least partially with the vibration dampers. The chassis arrangement further has at least one stabilizer. During transverse accelerations below a threshold acceleration the stabilizer contributes to the body control less than the vibration dampers and contributes more than the vibration dampers from the threshold acceleration upward.

A stabilizer bar assembly for a suspension system of a vehicle. The stabilizer bar assembly includes a first bar configured to be coupled to the vehicle suspension system proximate to a first wheel. A second bar is adjacent to the first bar. A coupling assembly is at an interface between the first bar and the second bar. The coupling assembly includes a magnetorheological material in contact with both the first bar and the second bar. The magnetorheological material is configured to transform from a fluid state to a viscoelastic solid state when subject to a magnetic field. A magnet is configured to apply the magnetic field to the magnetorheological material. In the viscoelastic solid state, the magnetorheological material resists relative movement between the first bar and the second bar.

Systems and method for assigning vehicle suspension dynamics are disclosed. Control signals that correspond to a current driving dynamic of a suspension system of a vehicle are generated. A vehicle state associated with the generated control signals is computed and a non-traditional suspension mode is selected. Based on the computed vehicle state and the selected suspension mode, a suspension height of the vehicle is adjusted.

Technology is provided for a pneumatic anti-roll system for use on a vehicle suspension. The pneumatic anti-roll system includes left and right side air springs connectable between a chassis of the vehicle and an axle of the vehicle suspension. Left and right side height control valves are mounted to the chassis and left and right side linkages connect between the left and right side height control valves and corresponding left and right end portions of the axle. Left and right side control air lines connect between the left and right side height control valves and corresponding left and right side air springs, respectively.

An adjustment system and method for adjusting a chassis property of a motor vehicle wherein an understeering sensitivity of the motor vehicle is increased upon detecting that a trailer has been coupled to the motor vehicle. A detection unit operates to detect when a trailer is attached or coupled to the motor vehicle.

A method for keeping a vehicle on course by determining a lateral acceleration of the vehicle; establishing a desired lateral inclination of the vehicle depending on the lateral acceleration determined in step a); adjustment of at least one actuator of an active chassis device of the vehicle, so the vehicle takes on the desired lateral inclination determined in step b); and c) carrying out a compensatory engagement by adjustment of at least one actuator of an active chassis device of the vehicle, so the vehicle takes on the desired lateral inclination determined in step b), wherein, in step d), at least one additional compensatory engagement is carried out by an additional active chassis device for the at least partial compensation of a yaw movement of the vehicle caused by the adjustment of the at least one actuator of the active chassis device.
