An electropneumatic trailer control-valve unit for a vehicle includes a storage port for coupling a store of compressed air for a trailer, a brake-pressure port, and a brake-pressure pilot-control unit configured to output at least one first control pressure. The electropneumatic trailer control-valve unit further includes a brake-pressure main-valve unit configured to receive the first control pressure and to output a brake pressure at a brake-pressure port, a trailer operating-pressure port configured to receive a trailer operating pressure; and a pneumatically switched trailer protection valve with a protection-valve control port which is connected to the trailer operating-pressure port for receiving the trailer operating pressure. The trailer protection valve switches from a first switching position into a second switching position if the trailer operating pressure exceeds a predetermined first threshold value.
