Features

FlexRay has three major features.

1. In-car LAN communication for X-by-Wire (-> CAN limit)
   
   • It has the data transfer method that transfers data periodically as a time trigger protocol
   • The maximum transfer rate of communication is 10 Mbps.
2. High-reliability-oriented communication protocol. Response to X-by-Wire application
   
   • Redundant communication. It enables fully-duplicated network configuration.
   • It enables schedule monitoring by hardware.
3. Support of flexible topology
   
   • FlexRay can support various types of topologies, such as Bus-type, Star-type, and Hybrid-type.
   • The segmentation of FlexRay is configured in combination of the fixed-length static segment that sends and receives messages with the fixed time trigger method and the dynamic segment that sends and receives messages with the flexible time trigger method
