A method for controlling the safe operation of a rear axle of a set of combined axles powered by a motor vehicle, particularly for a vehicle designed to carry loads and which have 6×4, 8×4 or 10×4 type traction configurations, or tridem models formed by three drive axles. The method includes a set of steps and activities that ensure proper and safe operation of systems and mechanisms for uncoupling and raising a rear axle of a vehicle, and more specifically checking a status of certain operating parameters of the rear axle and of the vehicle itself in order to permit or prevent uncoupling and coupling, as well as raising and lowering of the rear axle of the vehicle.

An air suspension control system is for a vehicle with a first and a second axle. The system has an auxiliary control unit connected to a main control unit via a data link.
