FlexRay™ Protocol based an Automotive Application

FlexRay™ protocol is developed to meet the demand of the next generation high capacity in-vehicle data communication. It is the high speed, deterministic, fault- tolerant and flexible protocol. There are large number of Electronic Control Units (ECUs) used in a high end automobile like car. Safety critical and high speed applications require such a protocol for enabling ECUs to communicate efficiently. In this work, we used Infineon SoCs as FlexRay™ nodes and establish communication between multiple nodes using FlexRay™ protocol. A simple automotive application is developed with temperature and magnetic field sensor being connected to a node and the sensor data is being communicated over the FlexRay™ network. Here, single code is written is for both coldstart nodes and non-coldstart nodes.
