Method and apparatus for controlling the brake application energy of electronic controlled braking systems of combinations of at least one tractor and one trailer

The wheel brakes temperatures are measured and compared with limiting values and between tractor and trailer. Dependent on the measurements the braking forces applied to wheels on either the tractor or the trailer can be increased, if the measured temperature is safely below the limit, or can be decreased to prevent overheating. If a coupling force regulation between the two vehicles is available this too can be regulated. The invention also relates to a corresponding arrangement for control of a tractor-trailer combination electronically controlled braking system.
