While working on control units that use the FlexRay bus (e.g. ABS and SRS on newer Audi models), we came across a clear and well-structured article on CAN Hacker.
The article “What is FlexRay” explains how this high-speed bus works in an accessible way: its difference from CAN, the TDMA mechanism, static and dynamic segments, frame structure and node synchronisation.
Useful reading for anyone dealing with diagnostics and repair of modern control units — sharing the link.
