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: An electropneumatic valve assembly is for activating a parking brake function of an electropneumatic brake system. The valve assembly has a pilot control unit and a main valve unit configured to actuate a parking brake pressure at least at one spring-accumulator connection. The valve assembly has a service brake connection for receiving a service brake pressure and a safety valve. The safety valve, by receiving a safety control pressure, is switchable from a venting position, in which the safety valve connects the pilot control unit to a vent, to a supply position, in which the safety valve supplies the pilot control valve with reservoir pressure, the safety valve remaining in the supply position or switching to the venting position as a function of an actuated pressure. The service brake connection is connected to the safety valve control connection.

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.

Abstract: An electronically controlled pneumatic brake system (2) for a vehicle 100, with a supply coupling head (24), a control coupling head (26), and an electronically controlled trailer control module (28) includes a first supply port (28.1), a trailer supply connection (28.2) for providing a trailer supply pressure (pT) to the supply coupling head (24), a trailer control connection (28.3) for providing a trailer control pressure (pB) to the control coupling head (26), an electro-pneumatic trailer control valve arrangement (40) for providing the trailer control pressure (pB), and a tractor protection valve electronic control unit (42). The electro-pneumatic trailer control valve arrangement (40) is configured to only supply a trailer control pressure (pB) to the trailer control connection (28.3) when compressed air is supplied to the trailer supply connection (28.2).

Abstract: In a vehicle combination including a hydraulically braked towing vehicle and a pneumatically braked trailer, a brake module serving as a trailer control valve has an electropneumatic pressure regulating module with an electronic controller that converts pressure signals from a sensor at a hydraulic pressure line from a hydraulically-actuated service brake master cylinder into control pulses for electromagnetic control valves in the regulating module. The control valves are connected via a pneumatic supply pressure inlet to a compressed air reservoir, and via a pneumatic control pressure outlet to a control pressure coupling head.
