A suspension control system includes: an acceleration module configured to determine a predicted lateral acceleration of a vehicle in the future based on a radius of curvature of a road a predetermined distance in front of the vehicle; and at least one of: a damping module configured to, before the vehicle reaches the curvature, selectively adjust damping coefficients of adjustable dampers of the vehicle based on the predicted lateral acceleration; and an active roll control (ARC) control module configured to, before the vehicle reaches the curvature, selectively adjust stiffness of ARC devices of the vehicle based on the predicted lateral acceleration.

A system for detecting and warning a user of an object in a path of a vehicle includes a detection module configured to detect an object in a path of a vehicle, and a control module in communication with the detection module. The control module is configured to receive vehicle data from one or more vehicle sensors, determine a height of the detected object, determine a ground clearance of the vehicle based on the received vehicle data, and in response to the height of the detected object being greater than a threshold based on the ground clearance of the vehicle, generate a signal to notify the user of the detected object. Other examples systems and methods for detecting and warning a user of an object in a path of a vehicle are also disclosed.

A process for correcting longitudinal roll from an offset load using active roll control within a vehicle is provided. The process includes, within a computerized controller using axle-based control to control a suspension system, operating programming to control pneumatic pressure supplied to each of a plurality of air spring devices within the suspension system to execute a vehicle leveling event including one of adjusting a height of the vehicle or maintaining the height of the vehicle. The process further includes operating programming to, simultaneously with the controlling the pneumatic pressure, utilize a plurality of active sway bars to provide an offset torque to the vehicle body. Each of the plurality of active sway bars is associated with one of a plurality of axles. Providing the offset torque is based upon a number of moles of air in each of the plurality of air spring devices and reducing the longitudinal roll.
