Electropneumatic brake control module for utility vehicles with redundancy pressure connector

An electropneumatic brake control module (1) for commercial vehicles (100), comprising:

• a supply port (2) for connecting a compressed air supply (3);
• a first axle channel port (4);
• a pneumatically controlled inlet/outlet valve unit (10) for outputting a first braking pressure (PB1) at the first axle channel port (4);
• an electropneumatic pilot control unit (8) for outputting at least a first control pressure (P1) at the inlet/outlet valve unit (10);
• a redundancy pressure port (6) for receiving a redundancy pressure (PR);
• and
• a redundancy valve unit (12) connected to the redundancy pressure port (6) for outputting a redundancy braking pressure (PBR) at the first axle channel port (4) in the event that the electropneumatic pilot control unit (8) has a fault;
• wherein the redundancy valve unit (12) has a redundancy valve (18), with a first redundancy valve port (18.1) connected to the redundancy pressure port (6), a second redundancy valve port (18.2) connected to the first axle channel port (4) and a third redundancy valve port (18.3) connected to a vent (5).
