Abstract: An electropneumatic control module has a trailer control unit, which has a trailer brake pressure port and a trailer feed pressure port, a holding brake unit, which has a spring-type actuator port and a holding brake pilot control unit, and an electronic control unit, which switches a holding brake pilot control unit into a ventilation position, wherein a second holding brake pilot control port is connected in pressure-conducting manner to a first holding brake pilot control port and the spring-type actuator port is connectable to a vent. The holding brake unit is connected to a redundancy port and is configured to output a first holding brake pressure at the spring-type actuator port when the holding brake pilot control unit is in the ventilation position and a redundancy pressure is provided. The trailer control unit outputs a brake pressure at the trailer brake pressure port when a redundancy pressure is provided.

Abstract: A compressed-air braking system of a tractor vehicle includes two service-brake circuits and a parking-brake circuit. A trailer control valve has a control input connected to a brake control line connected to a brake line of one of the service-brake circuits and an inverted control input connected to a further brake control line routed to a brake line of the parking-brake circuit. A valve device for braking a coupled trailer vehicle independently of the foot-brake valve has an electronically controllable valve unit arranged in the further brake control line routed to the inverted control input of the trailer control valve. Via the valve unit, the portion of the further brake control line on the trailer control-valve side can be connected alternately to the portion on the parking-brake valve side or to a depressurizing output.
