Diseño de una interfaz para el monitoreo del banco didáctico funcional de dirección con asistencia eléctrica de la Carrera de Ingeniería Automotriz de la Universidad Politécnica Salesiana, Quito, Campus Sur

Abstract

The document discusses the creation of an interface for the monitoring and control of an educational electric power steering (EPS) bench, used in the teaching of automotive engineering. Electronic components such as Arduino, MPU6050, MCP2515, and a Nextion display, along with CAN bus and Bluetooth communication, are employed to develop an educational interface that allows students to better understand EPS systems. The importance of EPS systems and their components, such as sensors that monitor steering torque, steering wheel angle, and vehicle speed, is highlighted. The methodology includes the integration of these sensors with ESP32 and Arduino, and the design of the interface on the Nextion display. The development of the necessary code to integrate these components and visualize data is crucial, utilizing specific libraries and functions. It is demonstrated how the created interface can improve the accuracy in the presentation of the vehicle speed PID controller data and verify its accuracy with values obtained from a scanner. The values provided by the MPU6050 sensor in terms of steering angle, steering torque, and steering wheel rotation speed are highlighted. The document also addresses current issues of educational interfaces that are limited in terms of interactivity and graphical data representation. It proposes the development of a customized interface that facilitates better data management and analysis, optimizing the teaching and training in automotive engineering. The need to accurately interpret the CAN bus data stream for effective maintenance of modern automotive systems is emphasized. The proposed interface seeks to improve user interaction and understanding, providing an educational tool for real-time data capture, interpretation, and application.
