Claim 15:
16. A data analytics system for a vehicle, the data analytics system comprising:
one or more controllers including a multi-layered control software architecture including two or more software layers and a health monitoring structure, the one or more controllers executing instructions to:
receive a fault;
in response to receiving the fault, generate, by the health monitoring structure, a plurality of unique triggers as the fault propagates throughout the multi-layered control software architecture;
build a network including a plurality of propagation paths, wherein each propagation path represents when the fault activates a first unique trigger in a lower software layer and propagates to a higher software layer to activate a second unique trigger;
identify one or more main propagation paths that are part of the network based on a data analysis of a mock big data set;
build a complete propagation pathway that includes two or more main propagation paths, wherein the complete propagation pathway follows the fault from a bottommost software layer to a global software layer of the multi-layered control software architecture;
in response to determining only one main propagation path exists within the network, determine a root cause of the fault based on the only one main propagation path; and
in response to determining more than one main propagation path exists within the network, confirm each of the more than one main propagation paths are valid based on one of the following: a timing signature of a specific main propagation path and a machine learning model.
