BRAKING SYSTEM, VEHICLE COMBINATION AND METHOD OF OPERATING THE SAME

The present invention refers to a braking system (100) for a vehicle combination, in particular for an electronic park brake control system or a global scalable air treatment system of a trailer-vehicle combination, comprising at least one truck park brake chamber (110), at least one truck park brake supply port (120), at least one secondary supply port (130), at least one secondary supply valve (140) and at least one control valve (150), preferably a select high valve, wherein the at least one secondary supply valve (140) comprises a fluid connection to the at least one truck park brake chamber (110) via the control valve (150) such that the at least one truck park brake chamber (110) can be provided with pressure fluid via the truck park brake supply port (120) and/or the secondary supply port (130). Moreover, the invention refers to a vehicle combination and a method for operating such a braking system and/or vehicle combination.
