Patent ID: 8267485

Claim:
A braking system for braking a drawbar trailer having axles including a front axle and at least one further axle, each of the axles having at least two wheels, the braking system comprising: first sensors for generating first sensor signals representing an axle load of at least one of the axles, ones of the first sensor signals being assigned to corresponding ones of the axles; second sensors for generating second sensor signals representing rotational speed of the wheels of the axles, ones of the second sensor signals being assigned to corresponding ones of the axles; an EBS modulator assigned to the front axle; a pressure accumulator for providing and storing a pneumatic operating pressure; brakes for braking the drawbar trailer, the brakes being actuable by a pneumatic brake pressure; at least one of a brake line and a transmission unit for transmitting brake signals generated in a towing vehicle between the towing vehicle and the drawbar trailer; a control unit configured to: receive the brake signals and the first and second sensor signals, and determine the axle load; and an adapter configured to adapt a value of the pneumatic operating pressure to the pneumatic brake pressure, the pneumatic brake pressure being feedable to the brakes by feed lines, the adapter being actuable by a drive unit; wherein the control unit is configured to: detect a value of the pneumatic brake pressure for actuating the brakes as a function of the axle load of the front axle and the at least one further axle as well as the received brake signals, and actuate the adapter such that the detected brake pressure is modulated with the same value at the front axle and at the at least one further axle.
