Patent attributes
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).
