Abstract

A suspension system for use on a vehicle having two or more rear axles. The suspension system includes a plurality of gas springs and plurality of height sensors capable of outputting signals having a relation to distances between the respective ends of the respective first and second rear axles and the sprung mass of the vehicle. A control system adapted to selectively inflate or deflate respective ones of the plurality of gas springs to thereby adjust a leveled orientation of the sprung mass. The control system includes a controller that is adapted to determine a rear axle vertical offset and a rear axle articulation offset. The controller is adapted to determine whether conditions are appropriate for adjusting the suspension system by comparing the rear axle vertical offset and/or the rear axle articulation offset to a corresponding vertical offset threshold and/or an articulation offset threshold. A method is also included.
