    Abstract: The invention relates to a pneumatic valve system (5) for a braking system of a towing vehicle. The pneumatic valve system (5) comprises a valve block (28) comprising a supply pressure inlet (29), a towing vehicle supply pressure outlet (30) and a towing vehicle control pressure outlet (32), as well as a control valve (6), a redundancy valve (7), and a brake valve (10). The pneumatic valve system (5) permits a redundant pressure supply of a brake cylinder of a parking brake of the towing vehicle by connecting the valves and the supply pressure outlet and outlets to one another in a very compact and stable manner.

    Abstract: A method of brake control of a vehicle combination (2) composed of a tractor vehicle (4) with an electronically controlled braking system (5) and a trailer vehicle (6, 8) with a pneumatically controlled pneumatic braking system (7, 9), involves introducing the brake control pressure (pBC) of the trailer vehicle (6, 8) into a tractor brake control line (19) extending to a tractor vehicle-side “brake” coupling head (26) via an electronically controlled trailer control valve (13) of the tractor vehicle (4). At the beginning of a braking operation, a pressure pulse (34) exceeding a target brake control pressure (pBC_soll) is introduced into the tractor brake control line (19). The volume of a trailer brake control line (28, 29, 32) coupled to the “brake” coupling head (26) is ascertained, and the absolute value (ΔpPI) and/or the duration (ΔtPI) of the pressure pulse (34) introduced are/is established depending on the ascertained volume.

    Abstract: Systems and methods for a vent interlock system to ensure vent cover closure prior to operation of a transportation vehicle. An embodiment of a system may include an interlock bar. The interlock bar may, in a lowered position, prevent a hydraulic valve handle of a hydraulic pump assembly from moving from an open position to a closed position, the hydraulic valve handle in the closed position to allow a vent cover of the trailer to be opened. The system may include a plunger valve connected to brakes of the transportation vehicle to lock the brakes of the transportation vehicle to prevent operation of the transportation vehicle when the interlock bar is raised. The system may include a spring operated latch attached to the transportation vehicle to hold the interlock bar in the lowered position via a notch or aperture in the interlock bar.

    Abstract: An electropneumatic valve unit (100, 200) for a vehicle brake system has a plurality of valve sections (102; 104; 106; 108; 204; 206) integrated into a single valve housing (101). The plurality of valve sections (102; 104; 106; 108; 204; 206) includes a front axle redundancy section (102) configured to provide a redundant supply or control pressure for controlling brakes associated with a front axle of a vehicle or a tractor, and a trailer control section (104; 204) for providing supply and/or control pressure to a trailer connected to the tractor. The redundant supply or control pressure for controlling brakes associated with the front axle of the vehicle at the front axle redundancy section (102) is derived from an output pressure of the trailer control section (104; 204).

    Abstract: A trailer brake control module (300a; 300b; 300c) for a towing vehicle (502) facilitating braking of a towed vehicle or trailer (504) includes a pressure supply port (P11), a trailer control pressure port (P22), a primary control port (P42) for receiving either directly and/or indirectly a control brake pressure for operating the trailer brake control module (300a; 300b; 300c). The primary control port (P42) receives the control brake pressure from a pneumatically operated pressure medium, a pneumatic control pressure line (308.1) provides alternative control brake pressure for operating the trailer brake control module (300a; 300b; 300c), wherein the pneumatic control pressure line (308.1) receives the alternative control brake pressure from an electronically operated pressure medium, and a relay valve (310) is activated using either the control brake pressure received at the primary control port (P42), or the alternative control brake pressure from the pneumatic control pressure line (308.1).
