Abstract:
1. An arrangement for controlling control devices in an on-board wiring system of a motor vehicle, in which the on-board wiring system has a bus system comprising multiple sub-networks of buses, each of the sub-networks of buses further comprising a plurality of control devices for controlling operating sequences in the motor vehicle, and in which the plurality of control devices are controllable by way of at least one access to a data transmission with a test instrument via a multifunctional data transmission device connected to an input side of the bus system, the multifunctional data transmission device being adapted to distribute the data transmission to the multiple sub-networks by using a hierarchically-defined criteria priority, and being connected to the multiple sub-networks directly in parallel to control in a parallel manner with respect to time the plurality of control devices distributed on the connected multiple sub-networks, wherein the hierarchically-defined criteria priority includes a first criterion corresponding to communication of the plurality of control devices among one another, a second criterion corresponding to utilization of the sub-network of buses during the data transmission, a third criterion corresponding to the data quantity to be maximally transmitted to the sub-networks, and a fourth criterion corresponding to the placing-together of control devices with the same operating conditions.
