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.

Method and apparatus for data interchange between a tractor vehicle and a trailer vehicle

A method for exchanging data in a vehicle train having a tractor, at least one trailer coupled to the tractor, and vehicle electronics allocated to the tractor and trailer interconnected via a PLC data bus used to provide programmed input and output functions for the vehicle electronics of the trailer. Data representing the programmed functionality is provided automatically and cyclically via the PLC data bus to the vehicle electronics. The vehicle electronics can be configured as ABS control electronics, the programmed input and output functions providing functionality beyond that of the ABS function. Control of these additional functions in the trailer vehicle electronics equipped with the specific functionality is then exercised via an input/output unit provided in the tractor and connected to the PLC data bus either directly or indirectly via the tractor ABS control electronics.
