A trailer brake control module () for a towing vehicle () facilitating braking of a towed vehicle or trailer () includes a pressure supply port (P), a trailer control pressure port (P), a primary control port (P) for receiving either directly and/or indirectly a control brake pressure for operating the trailer brake control module (). The primary control port (P) receives the control brake pressure from a pneumatically operated pressure medium, a pneumatic control pressure line () provides alternative control brake pressure for operating the trailer brake control module (), wherein the pneumatic control pressure line () receives the alternative control brake pressure from an electronically operated pressure medium, and a relay valve () is activated using either the control brake pressure received at the primary control port (P), or the alternative control brake pressure from the pneumatic control pressure line ().

Trailer brake control module

An electropneumatic trailer control module () includes a trailer control connection () configured to deliver a trailer control pressure (pTC), an electropneumatic trailer control valve arrangement () configured to receive a supply pressure (pS) and to provide the trailer control pressure (pTC) and an electronic trailer control connection () for providing trailer braking control signals (STB) such that the trailer control pressure (pTC) can be modulated. The electropneumatic trailer control module () is characterized by a protection connection () for receiving a pneumatic protection pressure (pPR), and a tractor protection unit () configured to switch between a supply state () and a protection state (). The invention further relates to an electropneumatic braking system (), a vehicle () and a method () for controlling a trailer supply function of an electropneumatic braking system ().
