Abstract
Multi-loss torque control systems and methods for an electric motor of an electrified vehicle include determining a torque command for the electric motor from a set of sensors, determining a speed loss for the electric motor based on an actual speed and a desired heat energy loss for the electric motor from the set of sensors, generating current commands for the electric motor based on its determined torque command and speed loss, controlling the electric motor using the generated current commands, capturing heat energy lost by the electric motor using a heat exchanger system, and using the captured heat energy in the heat exchanger system to heat a component of the electrified vehicle.
