Abstract
The present disclosure relates to systems and methods of dynamically modulating use of various motor control strategies (MCSs) to optimize powertrain efficiency. One or a combination of MCSs are strategically and dynamically implemented to regulate torque to drive axle motors based on vehicle operating conditions. In normal acceleration conditions, Field-Oriented Control (FOC) may regulate torque applied to a first drive axle motor and Direct Torque Control (DTC) may regulate torque applied to a second drive axle motor, where the first drive axle motor may operate at peak efficiency and the second drive axle motor may compensate for fluctuating torque demand. In cruising speed conditions, FOC may regulate torque applied to both the first and second drive axle motors to operate with high steady-state efficiency.
