Desenvolvimento de unidade de controle veicular para veículos elétricos

Abstract

This work presents the development of a Vehicle Control Unit (ECU) for electric vehicles in Formula SAE competitions, focusing on torque management and communication with the frequency inverter to improve drivability and safety. The methodology follows the V-model, covering everything from requirements gathering (such as throttle signal reading, traction control, temperature monitoring, and CAN communication) to development and testing. The firmware was developed in Simulink, allowing efficient simulations, while the hardware, featuring the ESP-32 as its main component, was designed in Altium Designer and industrially manufactured. The ECU met the functional requirements, but CAN network validation still needs improvement. The software is adaptable to different competition vehicles and can serve as a development foundation for various teams.
