FlexRay – ISO 17458<\/h2>\n\n

FlexRay is a serial, deterministic, and fault-tolerant fieldbus system<\/strong> designed for use in the automotive industry. It was developed primarily for use in X-by-Wire applications. These applications require a higher data transfer rate<\/strong> than can be achieved with the CAN bus. To ensure rapid and cost-effective implementation, the leading German automakers collaborated on this new development. The goal was to create a new open standard similar to the CAN bus. <\/p>\n\n

Physical Layer and Topology<\/h3>\n\n

In principle, it is also possible to use a line topology with FlexRay, similar to that used with the CAN bus. Ideally, however, the active star topology is used, in which the star point actively generates the required signals. Hybrid configurations combining both variants are also feasible. <\/p>\n\n
