Abstract
This study presents a novel methodology to enhance the energy efficiency of Electric Vehicles (EVs) while maintaining dynamic stability and driving comfort, even on uneven roads, using onboard vehicle measurements. The approach involves a hierarchical control scheme that integrates a model predictive controller with a torque vectoring algorithm to optimize torque demand and accurately anticipate road-specific torque requirements. The control is implemented on EV with Interior Permanent Magnet Synchronous Motors (IPMSM) as four wheel drives. The optimal torque control is realised through an Artificial Neural Network (ANN)- based motor torque control scheme. The design is validated through tests in real-world driving scenarios. In comparison with conventional methods, the proposed method shows a 37% increase in energy efficiency across different test conditions, thereby resulting in an increase in EV driving range. These advancements are achieved without substantial modifications to the EV’s drivetrain, representing a significant step forward in sustainable and efficient electric mobility.
