Abstract
A novel method is proposed and described, which increases the efficiency of an electric 4WD vehicle by dynamically redistributing torque to shift motor operating points toward more efficient locations. This method operates in parallel with active stability controllers, by considering tire capacity and vehicle dynamics within the energy optimization loop. Simulations are performed for an electric vehicle with four independent AC induction motors, and 5-7% improvements to energy usage are shown in standard EPA drive cycles.
