Claim 14:
15. A method for determining a root cause of a fault by a data analytics system for a vehicle, the method comprising:
receiving, by one or more controllers, a fault, wherein the one or more controllers including a multi-layered control software architecture including two or more software layers and a health monitoring structure;
in response to receiving the fault, generating, by the health monitoring structure, a plurality of unique triggers as the fault propagates throughout the multi-layered control software architecture;
building 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;
identifying one or more main propagation paths that are part of the network based on a data analysis of a mock big data set;
building 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; and
in response to determining only one main propagation path exists within the network, determining a root cause of the fault based on the only one main propagation path.
