High-performance embedded ECU based on STM32 ARM Cortex-M4 with advanced FOC motor control, BMS integration, vehicle communication and full production-ready software architecture.
AuMi's eBike Control Unit project delivers a production-grade ECU platform centred on the STM32 ARM Cortex-M4 — one of the most capable embedded controllers for real-time motor drive applications. The system integrates advanced Field-Oriented Control (FOC) algorithms for BLDC and PMSM motors, providing smooth, efficient torque delivery across the full operating range.
The ECU integrates battery management, charger control, display interfaces and sensor fusion in a single, compact hardware design. Vehicle communication and diagnostics are implemented using CAN bus and standard automotive protocols, enabling fleet-level monitoring and OTA firmware upgrades.
The project scope covers hardware architecture, embedded software, motor control algorithm tuning, system integration and complete vehicle-level validation — producing a scalable controller platform suitable for multiple vehicle categories.
Advanced FOC with SVPWM minimises switching losses and maximises range per charge cycle.
Optimised torque maps and regenerative braking strategies extend operational range significantly.
Modular hardware and software architecture scales across light cargo, commuter and performance vehicle categories.
Safety-critical embedded software with fault protection, watchdog management and fail-safe degradation modes.
Reusable BSP, driver libraries and control framework cut time-to-market for next vehicle platforms.
Seven parallel engineering tracks covering hardware, software, integration and validation.
STM32 ARM Cortex-M4 hardware design, MCU selection, peripheral mapping and PCB architecture for the control unit.
FOC algorithm implementation with SVPWM, current regulation loops, speed and position estimation using sensorless techniques.
BMS communication, state-of-charge estimation, cell balancing interface, charger control and thermal management.
CAN bus implementation, display protocol integration, OBD-style diagnostics and OTA firmware update support.
Overcurrent, overvoltage, thermal and rotor-lock protection with watchdog supervision and fail-safe response.
Ride-mode calibration, torque map tuning, regenerative braking configuration and real-world range validation.
Complete electrical and mechanical system integration — wiring harness, connector design and vehicle-level validation.
Milestone plan from Mar 2026 through SOP in 2027. Current date marked in red.
