What is FlexRay?

FlexRay is a high-performance network designed for determinism, safety, and reliability. It supports single or dual-channel operation to provide fault tolerance, and it can be configured as a star or in a passive bus configuration. Mixed configurations are possible.

What is FlexRay used for?

FlexRay is a high-performance network technology designed for automotive applications such as x-by-wire and engine control.

What are the physical characteristics of FlexRay?

FlexRay is targeted to support data rates of up to 10 Mbits/s. It can support a cascaded star architecture with up to three hops between nodes. It supports a low-power sleep mode as well as normal mode. The node connection is a terminated, unshielded twisted pair (UTP). Improved EMC performance is possible using a shielded twisted pair (STP). FlexRay is 14- and 42-V battery-voltage compliant.
