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 of a drive axle based on vehicle operating conditions. In normal acceleration conditions, Field-Oriented Control (FOC) may be used to regulate torque applied to a first drive axle motor and Direct Torque Control (DTC) may be used to regulate torque applied to a second drive axle motor of the drive axle, where the first drive axle motor may operate at peak efficiency and the second drive axle motor may make up for fluctuating torque demand. In cruising speed conditions, FOC may be used to regulate torque applied to both the first and second drive axle motors to operate with high steady-state efficiency at cruising speeds.
