An electronic brake system for a trailer with a pneumatic brake installation is disclosed. The electronic brake system comprises a brake controller (18) in the trailer (11) connected to a first communication device (20) that is part of a first communication channel (23) for wirelessly receiving brake signals of a towing vehicle (10). The electronic brake system also comprises a second communication channel for receiving brake signals of the towing vehicle. The brake controller (18) converts the brake signals of the first communication channel (23) into brake commands for the pneumatic brake installation only if brake signals arrive via the second communication channel (24) at the same time or within a defined time window. The time window begins as soon as a brake signal arrives on one of the first and second communication channels (23, 24).

A braking system may include an enclosed cylinder and a double-sided piston assembly disposed therein. The double-sided piston assembly includes a first piston disposed within the enclosed cylinder, a second piston disposed within the enclosed cylinder, and a linear piston leg connecting the first piston and the second piston. The linear piston leg includes two opposite racks. A segmented pinion is disposed between the two opposite racks, where the segmented pinion includes a cogged segment and a cogless segment. The cogged segment and the cogless segment are on opposite sides of the segmented pinion. A brake shaft is connected to and rotatable with the segmented pinion. A transmission system is configured to couple the brake shaft to a drive shaft of a vehicle. Compressed air or oxygen may be drawn in or discharged from the enclosed cylinder via a one-way inlet valve and a one-way outlet valve.

Electric equipment for a vehicle with an electropneumatic service brake device, in which at least one pneumatic brake control pressure is immediately and directly controlled to the electromagnetic backup valve, which is still being closed by a current, of at least one pressure regulating module in response to an assistance brake request signal regardless of a defect of an electric service brake circuit. For a failure of the electric service brake circuit, the electromagnetic backup valve, which is then in the currentless state, of the at least one pressure regulating module is automatically opened, and the brake pressure is immediately formed in the pressure regulating module based on the at least one pneumatic brake control pressure already present in the pressure regulating module. Thus, the reaction time of a pneumatic redundancy of the electropneumatic service brake device in response to electric defects is reduced.
