NETWORK SYSTEM FOR TRANSMITTING VEHICLE DATA

摘要

A network system for transmitting vehicle data has a bidirectional multidrop ring in which data communication between data transmitting nodes and corresponding data receiving nodes is carried out even if a breakage or some other trouble occurs at a portion of the multidrop ring. This system ensures safe and reliable control of various vehicle loads for a long period of time. At least one multidrop bus or at least one bidirectional multidrop ring is electrically connected to the first-mentioned bidirectional multidrop ring, thereby widening the applicability of the system to the control of vehicle loads.
