Executive Summary

FlexRay protocol is emerging as the next generation automotive communication protocol which offers high data rate, deterministic, fault tolerant, flexible in-vehicle data communication. This protocol supports both time triggered and event triggered data communication. The network that uses FlexRay protocol is called FlexRay network. The need for FlexRay protocol is the substantial demand for the high capacity in-vehicle data communication between the electronic components. In this paper, the authors 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.
