Abstract
Todayâs vehicles include a complex symbiosis of intelligent electronic systems and integrated mechanical structures. In-vehicle networks provide an efficient method of communication between the various electronic components in an automobile. The communication protocols discussed in this paper are Local Interconnect Network (LIN), Controller Area Network (CAN) and FlexRay. LIN is used in low speed applications, CAN are used in medium speed applications and FlexRay is used in high speed applications. A gateway is a network node used to transfer data from one communication protocol to another. Vector CANoe is an all-round tool for the development, testing and analysis of entire ECU networks and individual ECUs. Vector CANoe uses a 3-phase development process that assists the user from the planning of the distributed system to the implementation of it. In this paper we have explained how to create 3 different networks (LIN, CAN and FlexRay) and also designed a gateway so that the messages can be transferred between different communication protocols. To start with we tested the design of the gateway using simulations and subsequently we have connected the necessary hardware and diagnosed the messages.
