Abstract
A trailer air supply and control module for a electronic brake system of a motor vehicle with a trailer interface, and a brake system of a motor vehicle with a trailer interface comprising the trailer air supply and control module, includes at least two electrical terminals configured to receive two independent but redundant electrical control input signals which comprise a signal for a preset brake control outlet pressure. At least one valve is configured to adjust a constant air pressure from an air pressure source to the preset brake outlet pressure. One pneumatic outlet terminal is configured to provide the preset brake supply outlet pressure to the pneumatic brake system of the trailer, and one pneumatic outlet terminal is configured to provide the preset brake control outlet pressure to the pneumatic brake system of the trailer. The air pressure source is arranged within the trailer air supply and control module.
