Abstract: A controller, while parameters are indicative of electromagnetic interference exceeding a predetermined value, generates voltage reference vectors or duty cycle commands such that differences between switching times of any two phases of an inverter are always greater than a threshold, and while the parameters are indicative of the electromagnetic interference being less than the predetermined value, generates the voltage reference vectors or duty cycle commands such that the differences are sometimes greater than the threshold and other times less than the threshold.

Abstract: Methods and systems are provided for adapting pulse width modulation with randomized zero-sequence components for control of an electrified powertrain of a vehicle. In one example, a method may include determining a zero-sequence voltage of an electric machine of the vehicle based on a random distribution, and adjusting a voltage reference signal of the electric machine based on the determined zero-sequence voltage to decrease ambient acoustic noise in the vehicle. In this way, spectral energy dispersion of pulse width modulated control of the electric machine may be increased without affecting torque production of the electric machine.

Abstract: This disclosure relates to an electrified vehicle and a method for providing driver feedback by producing a torque ripple. An exemplary electrified vehicle includes, among other things, an electric machine configured to generate a torque output, and a controller configured to selectively adjust the torque output to produce a torque ripple in response to a triggering event.

Abstract: A vehicle alert method includes, among other things, in response to an alert event, altering at least one characteristic of power delivered within an electrified vehicle powertrain to provide an alert. A vehicle alert assembly includes, among other things, a power characteristic control system that, in response to an alert event, alters at least one characteristic of power delivered within an electrified vehicle powertrain to provide alert.
