Abstract

A method for establishing a wireless connection between a first transceiver in a trailer vehicle (12) having an electronic braking system and at least one second transceiver outside of the trailer vehicle (12) is disclosed. The first transceiver is assigned to an electronic control unit (14, 22) in the trailer vehicle (12), which is coupled to a tractor vehicle (10) and a wired connection (15, 16, 17) exists. In the method, a) a trigger signal is generated in the tractor vehicle (10) and transmitted the control unit (14, 22); b) the first transceiver establishes a preliminary connection to the at least one second transceiver, c) the at least one second transceiver indicates via an output unit the preliminary connection, and d) if conditions are met, a permanent connection between the first transceiver and the second transceiver is established.
