FlexRay
FlexRay is a fast, time-controlled vehicle network used for safety and chassis systems.
What is FlexRay?
It is faster than CAN. It is used for active suspension and steering systems in some cars. It uses two channels for redundancy. Its deterministic timing suits systems that need reliable, fast communication. Newer architectures increasingly use Ethernet alongside CAN. It was introduced in some premium models for systems such as adaptive dampers and active steering. Wiring repairs must keep the twisted pair and connector specifications intact.
