Abstract

A method is disclosed for the operation of a data processing system for motor vehicles including at least two computers and a line connecting the computers for the transmission of messages. This line permits a fast and reliable data transmission between the computers installed in the motor vehicle, taking into account the specific requirements of a controller-coupling in the motor vehicle. An embodiment is provided which describes in detail the interface between the individual computers and the line linking the computers, and with the aid of which a controller-coupling is realized in the vehicle.
