Dual-motor electric vehicles require independent torque distribution between front and rear axles to optimize vehicle stability and energy efficiency.
Model Predictive Control (MPC) is preferred in Simulink because it solves a multi-objective optimization problem at each time step while enforcing strict hardware limits:
- Constraint Handling: Prevents motor over-torque, tire slip, and excessive battery discharge.
- Efficiency Optimization: Balances power split dynamically between drive motors, extending total battery range by up to 8–12%.
- Handling & Traction: Adjusts yaw moments in real time during aggressive cornering or slippery road conditions.
