ABSTRACT:
A system and method for controlling brake actuation energy in electronically controlled brake systems of tractor and trailer vehicle combinations. The temperatures of the brakes of the tractor and trailer vehicle parts are determined and compared with one another and with a preset temperature limit value. If the determined temperatures differ by at least a preset value and the temperatures of the brakes of at least one vehicle part reach the temperature limit, less brake actuation energy is provided to the brakes of the vehicle part having the higher temperatures, while more brake actuation energy is provided to the brakes of the vehicle part having the lower temperatures, and coupling force control is deactivated or programmed to adjust a coupling force which is not zero but the magnitude of which depends on the temperature induced changes of the brake actuation energy.
