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.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
