ABSTRACT:
A braking system for controlling the braking of a trailer as a function of the load condition of the trailer, determined by variables measured only on the tractor. In the tractor, a proportional valve is provided which is controlled by an electronic brake control system and, as a function of the determined load condition, provides the brake pressure for the trailer. The connection of a driver brake valve to a trailer brake valve with a select-high function is controlled by at least one fail-safe valve, which is controlled by the electronic brake control system. In normal operation of the electronic brake system, the output of the proportional valve is the output of the trailer brake valve and in faulty operation of the electronic brake system, the output of the driver control valve is the output of the trailer brake valve.
