Abstract: Systems and methods for commanding an electric drive system for an electric or hybrid vehicle are described. In one example, the drive system is commanded by a controller that supplies a pulsed torque command that varies in frequency as a function of time when a driver of a vehicle requests a constant driver demand torque.

Abstract: A computer includes a processor and a memory, and the memory stores instructions executable by the processor to receive time-series data from sensors of a vehicle, determine an efficiency of the vehicle, and determine a probability of a fault occurring in the vehicle based on the time-series data and on the efficiency. The efficiency is energy consumption by the vehicle per distance traveled by the vehicle.

Abstract: Systems and methods for commanding an electric drive system for an electric or hybrid vehicle are described. In one example, the drive system is commanded by a controller that supplies synchronized pulsed torque commands that vary in magnitude and/or phase as a function of time when a driver of a vehicle requests a constant driver demand torque.

Abstract: Systems and methods for commanding an electric drive system for an electric or hybrid vehicle are described. In one example, the drive system is commanded by a controller that supplies different D-axis and Q axis command signals. The different D-axis and Q-axis command signals permit adjustments to alter vehicle noise and vibration levels.

Abstract: Methods and systems are provided for an insulation system of a stator. In one example, a method may include receiving images of the stator at a processor of a computing system and feeding the images to a deep learning tool to generate processed images by segmenting and cropping the images according to slots identified in the images. Further, the varnish in the processed images may be quantified based on fluorescence of the varnish, converted into estimated varnish fill percentages, based on an output from analysis of the processed images, and the estimated varnish fill percentages may be displayed in a report.

In one example, a method may include receiving images of the stator at a processor of a computing system and processing the images by converting the images to one or more of cluster-only images and binary masks. The images may be fed to an artificial intelligence (AI) model to obtain one or more of varnish estimates and void estimates to generate a training dataset which may be used to train a deep learning tool to estimate varnish fill percentages from the images and display the varnish fill percentages at a display device.

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: Disclosed are various examples of providing cross platform accelerator remoting between complex instruction set computer (CISC) components and reduced instruction set computer (RISC) components of a computing environment. An accelerator remoting server receives accelerator instructions executable by a locally installed accelerator device and provides the accelerator instructions to the accelerator device. The accelerator remoting server transmits accelerator results to an accelerator remoting client to complete the cross platform or platform agnostic accelerator remoting.

Abstract: Methods and systems are provided for adaptive pulse width modulated control of an electrified powertrain of a vehicle. In one example, a method may include perturbing a switching frequency for pulse width modulated control of the electrified powertrain, and, responsive to sound measured in a vehicle cabin indicating a noise improvement after the perturbation, controlling the electrified powertrain with the perturbed switching frequency. In this way, acoustic emissions from an electrified powertrain may be reduced.
