Using the FlexRay interface for automotive tests

At the end of the 1990s, the FlexRay consortium was founded to meet the increased requirements of OEMs in terms of bandwidth and transmission reliability. The consortium's goal was a new, fault-tolerant, time-controlled communication system with transmission rates of up to 10 MBit/s.

The FlexRay communication system that emerged from the consortium is used in vehicles, especially for X-by-Wire applications (e.g. steer-by-wire, drive-by-wire), primarily because of its determinism, fault tolerance and high speed. The bus system can be realised in star topology as well as in line or bus topologies. A two-channel system (A and B channel) allows data to be transmitted redundantly. Similar to CAN or LIN, the coupling to the bus medium is implemented by a transceiver.

In the deterministic communication system, the media access procedure on a channel is time-controlled and therefore predictable (TDMA Time Division Multiple Access). When configuring the network, a global cyclic transmission plan (schedule) determines at which time a node or station is allowed to transmit. In addition to the static segment with the precisely defined time and thus transmission slots, there is a dynamic segment for optimal utilisation of the available bandwidth. The communication and access procedure in the dynamic segment is more comparable to that of the CAN bus.
