FlexRay

A rugged, digital, in-vehicle serial bus from the FlexRay Consortium, founded by BMW, DaimlerChrysler, Freescale Semiconductor and Philips Semiconductor in 2000. First used in the 2007 BMW X5, FlexRay provides 10 Mbps on each of two channels; much faster than the CAN bus maximum of 1 Mbps. Using both bus and star topologies, FlexRay supports synchronous and asynchronous transmission, fault tolerance and a guarantee of minimum latency. For more information, visit www.flexray.com. See automotive systems and automotive Ethernet.

The SecureCAR SDK enables the integration and execution of Trillium's patent pending SecureCAR software module within automotive ECU application software, encrypting and authenticating the messages of in-vehicle networks like CAN bus, LIN bus, FlexRAY and Ethernet for realtime actuation applications.
Depending on the setup, multiple real ECUs have to be included in the test bench and connected via automotive network systems, like CAN, FlexRay, or Automotive Ethernet.
As requirements for data transfer become more advanced, many vehicle designs may use a combination of protocols alongside CAN such as LIN, FlexRay, SENT, and, more recently, Ethernet.

Also, our choice of a time-triggered paradigm falls in line with the increased ongoing efforts towards the standardization of in-car communication networks, such as FlexRay and Time-Triggered Ethernet (TTEthernet or TTE), with the overall goal of guaranteeing highly reliable, deterministic, and fault-tolerant system performance [11].
These include dedicated trigger functions for FlexRay, CAN, LIN, UART, I2C and SPI serial bus patterns as well as the ability to perform simultaneous analyses on two different buses operating at different speeds.
