Telemetry System for Real-Time Monitoring of a Formula Student Electric Vehicle

Abstract: Real-time monitoring of vehicle data during testingcan drastically cut down on test times as well as improve thequality of testing by facilitating the implementation of run-timecompliance verification with expected model behavior, along withanomaly detection in both hardware and software. By providinga wireless communication link between vehicles and a monitoringbase station, this project aims to build the groundwork formore sophisticated testing proceedings in the future. The wirelesscommunication system implemented in this project mirrors datafrom the two CAN data busses on the vehicle and transmits themvia a licence-free 868 MHz ISM band. The receiver is connectedto a computer where the data can be visualized and analyzed inreal-time. The project goals were exceeded in both throughputand range. Early testing has shown that data rates of 150 kbit/sand ranges 1.2 km and beyond are achievable. The project has seta solid foundation upon which wireless testing routines can nowbe developed. Hardware and software developed in this projectcan be built upon and optimized further in future revisions toachieve even higher data rates and longer ranges.
