ABSTRACT:
A method for controlling a braking device equipping a trailer includes braking the towing vehicle. The force induced in a coupling device is measured, at least at a given moment, and compared with a target value. When the difference between the force and the target value deviates from a predetermined tolerated threshold, the braking elements may be actuated. The method may be repeated until the difference between the intensity of the measured induced force and the target value is less than the predetermined tolerated threshold. The moment when the towing vehicle and the trailer are about to roll may be detected and monitored. Starting from that moment, the intensity of the force induced in the coupling device is measured and the average of the intensity of the induced force may be calculated and stored. The target value may be the average value of the induced force.
