Abstract
A system and method for braking a drawbar trailer having a front axle and one or more further axles, each axle having at least two wheels, includes first sensors which sense the axle load of at least one axle, and second sensors which sense the rotational wheel speeds. Brakes actuatable with a pneumatic brake pressure brake the trailer. Brake signals generated in the towing vehicle are transmitted between the towing vehicle and the trailer. A control unit receives these brake signals and the sensor signals, and determines the axle load. The operating pressure is adapted to the brake pressure which is fed to the brakes. The control unit detects the brake pressure value as a function of (i) the specific axle loads of the front axle and the other axles and (ii) the received brake signals, and actuates the brakes such that the detected brake pressure is made available.
