Wiring for motor vehicles, and process for operating it

Abstract

Abstract The electrical system for motor vehicles contains a multiplex control for switching, controlling and monitoring electrical terminal devices such as switches, controls and display elements, sensors and actuators and consists of a plurality of bus subscriber stations (2) coupled to a bus line (1), in addition of interface devices (4) assigned to the bus subscriber stations via signalling lines in a star shape and of terminal devices assigned in groups to the interface devices. The interface devices (4) contain signal converters and a data processor and transmitter/receivers for exchanging data signals with the associated bus subscriber station. The operation of the electrical system occurs in such a way that the transmission of the data signals from a bus subscriber station to the associated interface devices is controlled by the bus subscriber station and occurs cyclically in the order of the groups of inputs and outputs of the respective interface device. In this case, the interface devices for transmitting a critically timed signal value can transmit a signal to the associated bus subscriber station at prescribed points of the transmission cycle, which signal leads to the interruption of the transmission cycle. <IMAGE>
