HAN Formula Student Team

This project documents my work in the HAN Formula Student electronics department as Junior Chief Electronics, with responsibility for the Electronic Throttle Control and driver communication systems.

The Electronic Throttle Control work focused on rule-compliant safety behavior for a Bosch throttle body controlled through an EMU Black ECU. The system was validated against Formula Student requirements for APPS and TPS plausibility, throttle return behavior, and immediate throttle shutdown when sensor signals became implausible.

I designed and evaluated the APPS signal strategy using voltage-divider calculations and Simscape electrical simulation, then tested ECU behavior through the wiring loom prototype. TPS implausibility shutdown worked as intended, while APPS tolerance issues revealed that the ECU expected a tighter relationship between the two pedal signals than the prototype reliably produced.

The report also covers the low-cost driver communication solution used during testing, the final vehicle electronics status after competition preparation, and recommendations for the next team, including improved APPS plausibility handling with an STM32/Simulink controller and more robust component validation before full-system integration.
