FlexRay is a communication protocol developed by the FlexRay Consortium. The core members of the Consortium are Freescale Semiconductor, Robert Bosch GmbH, NXP Semiconductors, BMW, Volkswagen, Daimler, and General Motors, and the protocol was respectively oriented towards embedded systems in the automotive domain.
