Integrated trailer control module with external electro-pneumatic parking brake unit

An electropneumatic trailer control module (1) for an electronically controllable pneumatic brake system (520) for a vehicle combination (500) with a tractor vehicle (502) and a trailer vehicle (504), the electropneumatic trailer control module (1) comprising:

• an electronic control unit (ECU),
• a pneumatic reservoir input (11), which is connectable to a compressed-air reservoir (525),
• a trailer control valve unit (65) with one or more electropneumatic valves (RV, IV, OV),
• a trailer brake pressure port (22), and a trailer supply pressure port (21), characterized in that the electronic control unit (ECU) has a parking brake signal input (200) for receiving an electronic brake representation signal (SB1, SB2, SB3) which represents an actuation of an immobilizing brake (6, 532a, 532b) of the tractor vehicle (502), wherein
• the electronic control unit (ECU) is configured to switch at least one valve (IV) of the one or more electropneumatic valves (RV, IV, OV) of the trailer control valve unit (65) based on the brake representation signal (SB1, SB2, SB3) for outputting a brake pressure (PB) at the trailer brake pressure port (22).
