Device and method for controlling control appliances in an on-board supply system of a motor vehicle
First Claim
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.

Abstract
An arrangement and method for controlling control devices in an on-board wiring system of a motor vehicle are provided, in which the on-board wiring system has a bus system divided into sub-networks of buses with groups of control devices for controlling operating sequences, and in which the control devices are controllable by way of at least one access to a data transmission via a test instrument. A multifunctional data transmission device is connected to the input side of the bus system, to which data transmission device the sub-networks are connectable directly in parallel and are controllable in a parallel manner with respect to time by way of several control devices distributed on the connected sub-networks. The sub-networks may be structured via a hierarchically defined criteria priority, which takes into account the communication required in the operation between the individual control devices within the sub-networks and between the sub-networks, as well as the data quantities to be transmitted to the individual control devices.

15. A method of controlling control devices in an on-board wiring system of a motor vehicle, the method comprising the acts of:
-
addressing a plurality of control devices, disposed in multiple sub-networks of buses, for a control of operating sequences for a data transmission by use of a test instrument; and by way of a multifunctional data transmission device, adapted to use a hierarchically-defined criteria priority, distributing the data transmission to the multiple sub-networks by addressing, in a parallel manner with respect to time, the plurality of control devices arranged in the multiple sub-networks of buses, the multiple sub-networks forming a bus system of the on-board wiring system of the motor vehicle connected to the test instrument by way of the multifunctional data transmission device, 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. - View Dependent Claims (16, 17, 18, 19)
