ABSTRACT:
An electronic bus system comprises a bus wire (BW) with at least two signal transmission wires (W1, W2) and a left and a right end, which are each defined by a terminating resistor connecting the signal transmission wires to each other. A plurality of electronic control units (ECU-ECUn) are between the two ends of the bus wire (BW) connected to the signal transmission wires (W1, W2) and are adapted, via these, to transmit and receive electric signals. The bus wire (BW) is divided into a plurality of sections (S1-Sn), which are interconnected by means of connecting circuits (CC1-CCn), and forms an annular unit. Each connecting circuit (CC1-CCn) comprises relay means, by means of which each connecting circuit, coordinated with the other connecting circuits, can connect at least one terminating resistor integrated therein, in order to define the left and/or right end of the bus wire (BW).
