Development of CAN Bus Converter for on Board Diagnostic (OBD-II) System

Abstract

CAN-bus technology is adapted in various vehicles to reduce the wiring harness and controls the vehicle exploitation physical system. In this paper, Control Area Network (CAN)-bus protocol is enforced employing a Single Board Computer (SBC) and access with each other by set a sender and receiver to get the data transmission. A special CAN-bus application layer protocol is intended for the high reliable and high period management network of the vehicle system. However not all microcontroller that used for Computer module in vehicle network had CAN-bus communication port. Thus the CAN-bus Converter is used as tool for converting data from a computer into an understandable language. The CAN-bus converter can also be used in various ways to obtain the final results of the data sent to it. Although different methods may be used, the most appropriate method cannot be identified. This project is therefore designed to find and evaluate which method is suitable for obtaining accurate data results and for avoiding abnormal data and data transfer speed.
