摘要：
Methods and systems are provided for producing a commanded torque in an electric motor in a vehicle. A method comprises obtaining a torque command, obtaining a speed of the electric motor, and operating the inverter based at least in part on a voltage command that corresponds to minimal current through the electric motor for producing the commanded torque at the instantaneous speed of the electric motor.
