1. A fault remediation system for a vehicle, the fault remediation system comprising:
one or more controllers in electronic communication with one or more consumed interfaces and one or more provided interfaces, wherein the one or more provided interfaces include an electronic all-wheel-drive (eAWD) system, the one or more controllers executing instructions to:
receive, from the one or more consumed interfaces, a consumed signal, wherein the consumed signal is generated by a sensor that is part of the vehicle;
perform fault detection upon the consumed signal to determine the presence of an active fault within the consumed signal;
in response to detecting an active fault with the consumed signal, select a remediation state from a group of two or more prospective remediation states based on a significance analysis of the consumed signal, wherein the remediation state addresses the active fault of the consumed signal, wherein the group of two or more prospective remediation states include two or more of the following: a related interface state, a secondary interface state, a fault-tolerant logic state, a last known good value state, and a constant value state;
evaluate a relevant subfunction that corresponds to the consumed signal that the remediation state addresses for the presence of remediation tolerance, wherein the relevant subfunction includes one or more of the following: feedforward control, lateral control, wheel control, and core arbitration;
generate arbitration instructions based on the remediation tolerance; and
execute the relevant subfunction that corresponds to the consumed signal that the remediation state addresses based on the arbitration instructions instead of deactivating the one or more controllers, wherein executing the relevant subfunction includes deactivating specific nested subfunctions that are part of the relevant subfunction.
