Abstract
Embodiments include a method for controlling a torque of an electric motor. The method includes receiving a requested output torque for the electric motor and obtaining a rotational speed of the electric motor. Based on determining that the rotational speed of the electric motor is within a predefined range, the method includes instructing the electric motor to operate at the requested output torque based on determining that the requested output torque is greater than a first threshold or less than a second threshold, instructing the electric motor to operate with a torque that is at least the first threshold based on determining that the requested output torque is less than the first threshold and greater than zero, and instructing the electric motor to operate with the torque that is at most the second threshold based on determining that the requested output torque is greater than the second threshold.
