Beschreibung
Zusammenfassung:	An automatic air suspension control system is provided for use in combination with a vehicle having a non-driven rear axle, a driven rear axle, and an air suspension associated with the rear axles to apply a load to each of the rear axles. The air suspension control system is programmed to maintain the load applied to the non-driven rear axle at a level that is less than the load applied to the driven rear axle until the load applied to the driven rear axle is equal to a threshold amount. The threshold amount may be equal to the maximum load that may be legally applied to the driven rear axle or some lower level. There may be no load applied to the non-driven rear axle prior to the load on the driven rear axle reaching the threshold amount or may be a non-zero amount.
