Develop an automotive network based on CAN/LIN bus

Abstract

It is a common knowledge that CAN network (or also called Controller Area Network) plays an increasingly fundamental role in automotive industries worldwide which migrates wiring systems of point-to-point connectivity to bus-related network of peer-to-peer one. It provides the backbone of in-vehicles network for other nodes transmitting and receiving data in bus with high speed and critical tasks. The LIN network (Local Interconnect Network), on the other hand, supplies an extended network to the system based on a master-slave architecture which merely requires one simple wire to deliver signals. Then the combination of CAN and LIN network would be a brilliant methodology for automotive network both in functionality and effectivity. It is the reason why the studied topic is such an indispensable demand in the internal company as well as on the global. Based on the principles of CAN and LIN network, it is necessary that the module and algorithm be proposed to construct the whole system. Successfully the system acquired capabilities of simulating internal signals and delivering data back and forth throughout the CAN/LIN bus. The system is also able to monitor and diagnose its own data from both CAN and LIN signals via a designed software, namely Busmaster. The following contents of this paper are going to explain and clarify what it is being done in the project as well as how the system is constructed.
