Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLC
Field: Computer technology (Electrical engineering)
Classification: CPC B  G | IPC B  G

Claim 7:
8. A method comprising:
receiving event data about an event associated with a subsystem of a vehicle, wherein the event includes an indication of an operating condition of the subsystem;
filtering the event data to remove outliers from the event data;
normalizing the filtered event data using a predetermined range;
selecting data from the normalized data that precede and follow the event;
determining deviations between reference data for the subsystem indicating normal operation of the subsystem and portions of the selected data that precede and follow the event;
determining whether the event data indicates a fault associated with the subsystem by comparing the deviations to a threshold deviation;
identifying one or more faulty components of the subsystem based on the deviations in response to the deviations indicating a fault associated with the subsystem;
updating a model trained to identify faults in vehicles to identify the event as a fault associated with the subsystem based on the event data in response to the deviations indicating a fault associated with the subsystem; and
updating the model in response to the deviations of the portions of the event data preceding the event being greater than the threshold deviation and in response to the deviations of the portions of the event data following the event remaining greater than the threshold deviation for a time period following the event.
