A data health monitoring and recording system for a vehicle includes a data recording infrastructure and one or more controllers. The one or more controllers include a multi-layer control software architecture including two or more software layers. The one or more controllers execute instructions to monitor, by a health monitoring structure that is part of the multi-layer control software architecture, one or more parameters calculated by each of the two or more software layers. The one or more controllers compare a respective parameter of a respective software layer with a predetermined corresponding performance metric for a required time horizon. In response to determining the respective parameter of the respective software layer does not meet the predetermined corresponding performance metric for the required time horizon, a trigger that instructs the data recording infrastructure to record the parameters calculated by each of the two or more software layers is generated.

Vehicle data health monitoring and recording system for multi-layer control software architecture

A system for vehicle motion control (VMC) performance enhancement utilizing real-time data reliability and criticality assessments includes a vehicle having sensors and actuators. The sensors collect real-time dynamic state information about the vehicle. The actuators actively and continuously adjust the dynamic state of the vehicle. The system executes a VMC application that obtains, from the sensors and actuators, dynamic state information of the vehicle, and estimates a real-time vehicle dynamic state from the dynamic state information. The VMC application determines a signal criticality and a signal reliability for vehicle dynamic state information, and executes a VMC strategy based on the real-time vehicle dynamic state, the signal criticality and reliability. The VMC application detects and mitigates signal degradation by enacting a VMC strategy, and generates a VMC output command to the actuators based on the VMC strategy. The VMC strategy actively, continuously, and automatically adapts to seamlessly overcome signal degradation.

A data analytics system for a vehicle includes one or more controllers having a multi-layered control software architecture including two or more software layers and a health monitoring structure. The one or more controllers execute instructions to receive a fault, and 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. The controllers build a network including a plurality of propagation paths and identify one or more main propagation paths that are part of the network based on a data analysis of a mock big data set. The one or more controllers build a complete propagation pathway including two or more main propagation paths. In response to determining only one main propagation path, the controllers determine a root cause of the fault based on the only one main propagation path.
