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

Claim 11:
12. A system comprising:
a processor; and
a memory storing instructions which when executed by the processor configure the processor to:
receive 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;
determine deviations between reference data indicating normal operation of the subsystem and portions of the event data that precede and follow the event;
determine whether the event data indicates a fault associated with the subsystem by comparing the deviations to a threshold deviation; and
update 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,
wherein the model is trained for use in the vehicles manufactured in a different vehicle program or a different model year than that in which the vehicle is manufactured; and

wherein the instructions configure the processor to update 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.
