Development of Real-Time Condition Check Systems for Racing Cars Using WCDMA

Abstract

As wireless mobile network services have been widely used these days, the development technology of WCDMA and their applications are gradually expanded, and thus there is a trend that a lot of IT fusion industries are emerging. In this study, a system was developed that utilize the OBD-II communication to import vehicle information and transfer data to an external server for other external devices to be able to real-time check the condition of a racing cars. A real-time condition check system for racing cars was implemented that reads information from the a variety of sensors inside the vehicle using the OBD-II scanner, converts the data for users to see easily, and transfers the data to external data server using a WCDMA module. An ordinary vehicle and a racing car driving at high-speed on the actual circuit were used for the performance test of the developed system; generated data were transmitted through the OBD-II scanner; it was confirmed that data were received without error and loss by the racing car state check system. In addition, it was also confirmed that the same data, as were transmitted to an external server using WCDMA, were sent and received normally. In the future, this technology will increase as part of a new automotive IT research fields.
