1. An air suspension control system for a vehicle having a first axle and a second axle, the air suspension control system comprising:
a main control unit for operating the air suspension control system;
an auxiliary control unit connected to said main control unit via a data link;
said auxiliary control unit having a pressure sensor associated with the first axle of the vehicle and configured to determine pressure measurements of the first axle as pressure sensor signals;
said auxiliary control unit having an input for receiving height sensor signals;
said input being connectable to a first height sensor arranged on the first axle for receiving first height measurements as first height sensor signals and to a second height sensor arranged on the second axle for receiving second height measurements as second height sensor signals;
said auxiliary control unit being configured to transmit at least one of the first height sensor signals, the second height sensor signals, and the pressure sensor signals to said main control unit via the data link; and,
said main control unit being configured to carry out on-board weighing for at least one of the first axle and the second axle in dependence on at least one of the first height sensor signals, the second height sensor signals, and the pressure sensor signals.
