Engineering Technical Specifications for Formula Student Electric Powertrain System (FSAE / FSTaiwan)

This engineering specification outlines the EV-Powertrain architecture, a sophisticated control system designed to transition student racing teams from traditional mechanical builds to software-defined vehicles. The framework emphasizes predictive control and high-precision communication, specifically utilizing EtherCAT to achieve microsecond-level synchronization across four-wheel independent drives. By replacing standard PID controllers with Model Predictive Control (MPC), the system can simultaneously optimize vehicle handling and energy efficiency while respecting complex physical constraints like battery heat and tire grip. Ultimately, the document serves as a strategic roadmap for integrating dual-domain isolation and advanced real-time computing platforms to ensure Formula Student competitors achieve both elite performance and strict safety compliance.
