Method for establishing a wireless connection
First Claim
1. A method for establishing a wireless connection between a first transmitter-receiver in a trailer vehicle with an electronic brake system and at least one second transmitter-receiver outside of the trailer vehicle, wherein the first transmitter-receiver is associated with an electronic control unit in the trailer vehicle, and wherein the trailer vehicle is coupled to a tractor vehicle and there is a wired connection through which signals can be transmitted from the tractor vehicle to the trailer vehicle, said method comprising the following steps:
- a) generating in the tractor vehicle a trigger signal and transmitting by cable the trigger signal to the electronic control unit in the trailer vehicle, wherein the trigger signal comprises switching on the ignition on the tractor vehicle,b) establishing by the first transmitter-receiver a provisional connection with the at least one second transmitter-receiver,c) indicating by the at least one second transmitter-receiver the provisional connection or a different type of confirmation request via an output unit, andd) establishing a continuous connection between the first transmitter-receiver and the at least one second transmitter-receiver if a confirmation signal arrives in the trailer vehicle as an acknowledgement of the confirmation request within a defined time period.

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.
