Abstract
A method and apparatus for data interchange between a tractor vehicle and a trailer vehicle coupled thereto. A first electronic device provided in or on the tractor is connected via a data link to a second electronic device provided in or on the trailer; the first and second devices being connected to sensors and/or actuators for controlling operating functions of the vehicle allocated thereto and for measuring status information. Initiated by an information request, the first device sends request data via the data link to the second device. The first device receives status information via the data link sent by the second device in response to the request data. The first device outputs, in a manner that correlates with the trailer, the received status information by means of an output device disposed on or in the tractor. The same output scheme is used for both the tractor and trailer.
