The invention relates to a method for controlling a vehicle combination (1) consisting of a tractor vehicle (1a) and a semitrailer (1b), wherein at least one support winch (16) having a leg member (16b) and a support foot (16c) fastened to the latter on the bottom side is arranged on the semitrailer (1b), wherein the leg member (16b) can be adjusted between an extended position (S1) and a retracted position, wherein the semitrailer (1b) is coupled to the tractor vehicle (1a) during a coupling operation, and/or the semitrailer (1b) is decoupled from the tractor vehicle (1a) during a decoupling operation. According to the invention, it is provided that the leg member (16b) in question is adjusted in automated fashion between an intermediate position and the extended position (S1), or vice versa, while the vehicle combination (1) is at a standstill and is in the parking position (PA), and/or the leg member (16b) in question is adjusted in automated fashion between the intermediate position (SZ) and the retracted position, or vice versa, while the semitrailer (1b) during the coupling process (AV) is moved away from the parking position (PA) or during the decoupling process (BV) is moved in the direction of the parking position (PA), in particular while the vehicle combination (1) is not at a standstill.

The present application pertains to a system comprising a multi-axle trailer with a front and a rear. The a multi-axle trailer comprises at least one lift axle configured to be raised or lowered to distribute weight, to increase trailer deflection during a turn, or both. A jeep is mounted between the trailer and a tractor wherein the jeep is configured to decrease weight on one or more axles. A booster is mounted to the rear of the multi-axle trailer. The system is configured such that during raising of the at least one lift axle an increase in air pressure to one or more other axles is increased to offset weight.
