摘要: The disclosure relates to the field of motor control, and more specifically, to a fault-tolerant control method and apparatus for an open-circuit fault in an alternating current motor and an inverter thereof, a computer device, and a computer storage medium. The method includes: A: determining, based on fault information of the alternating current motor and the inverter for driving the alternating current motor, a rotor fault position interval corresponding to each fault phase in one or more fault phases; B: establishing a fault-tolerant control constraint model, where the fault-tolerant control constraint model includes an open-circuit fault equation applicable to each fault phase for the corresponding rotor fault position interval; and C: determining, with the fault-tolerant control constraint model as a constraint, a phase current reference value by using a fault-tolerant control algorithm.

摘要: The disclosure provides a vehicle fault diagnosis method and device, and a computer-readable storage medium. The vehicle fault diagnosis method includes: receiving a grayscale image, where the grayscale image represents diagnostic data for vehicle diagnosis; extracting features from the grayscale image by using a convolutional neural network, to generate a feature map; performing self-attention-based processing on the feature map to obtain a classification result, where the classification result indicates a vehicle fault condition; and performing a relevance propagation analysis based on the classification result to obtain a contribution heat map, where the contribution heat map indicates a degree of contribution of each pixel in the grayscale image to the classification result.
