1. A suspension control system comprising:
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;
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,
wherein the damping module is configured to: set the damping coefficients based on leftward predicted lateral acceleration such that the adjustable dampers on the left side of the vehicle have higher damping coefficients than the adjustable dampers on the right side of the vehicle; and set the damping coefficients based on rightward predicted lateral acceleration such that the adjustable dampers on the right side of the vehicle have higher damping coefficients than the adjustable dampers on the left side of the vehicle; 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.
