Descripción
A system was developed to emulate a powertrain, integrating an RS-550 DC motor, a servo controlled by an Arduino program on an ESP32 to simulate the throttle valve, and an automatic transmission emulation. A pedal with a potentiometer adjusts PWM, managed by an L298N module, while a Hall effect sensor measures RPM and speed. Characterization was conducted across frequencies from 100 Hz to 19 kHz, analyzing residuals and coefficients of determination (R2 up to 0.9919). Residual dispersion, with standard deviations ranging from 150 RPM to 340 RPM, was evaluated using Gaussian distributions and boxplots, identifying symmetric fits within ±2σ. Linear fit validation compared outliers and variability, prioritizing precision and noise reduction. This approach proposes a robust model for automotive simulations, optimizing powertrain control.
