  "textContent": "Method for braking control of a vehicle combination, which consists of a towing vehicle with a hydraulic or pneumatic braking system as well as at least one coupling-capable trailer with a pressure-controlled pneumatic braking system, and in which an electronic brake control valve (2) is used, which has at least two solenoid shut-off valves which can be controlled by an electronic control unit (8), which are configured as an inlet valve (12) and an outlet valve (14), whereby by means of the brake control valve a brake control pressure (pBC) can be generated in a brake control line (42, 42') extending from a brake control outlet (p22) of the brake control valve to a coupling head \"Brake\" (6) of the towing vehicle or to a trailer brake valve of the trailer and/or a coupling head \"Brake\" at the rear of the trailer, and in which to determine the trailer status it is established whether the towing vehicle is connected to a trailer and/or what the line volume (VBC) of the brake control line is. It is provided herein that a target pressure (pz) to be set in the brake control line is specified, that this is controlled into the brake control line by pulsating opening of the inlet valve and/or the outlet valve, that the brake control pressure in the brake control line is measured during pressure build-up, and that from the temporal pressure profile of the brake control pressure and/or the switching states of the inlet valve and/or the outlet valve up to reaching the target pressure, a characteristic parameter for the trailer status and/or the line volume of the brake control line is determined.",
