Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles, especially autonomous ones, face challenges in detecting fault conditions in their numerous components and determining appropriate responses, as existing technologies lack efficient methods for self-detection and communication of faults across complex vehicle ecosystems.
Innovation Solution
A computer-implemented method and system for vehicle component fault detection, which involves self-detection of faults, generation of device health codes with multiple tiers of information, and broadcasting these codes on various vehicle communication networks, including time-sensitive networks, to facilitate appropriate vehicle responses and machine learning-based refinement of reaction strategies.

Engineering Contradiction Analysis
1Reliability
If vehicle components self-detect faults and broadcast detailed health codes across multiple communication networks, then fault detection capability and response time are improved, but device complexity and communication overhead increase
Solution Approach 1:
The health code is segmented into multiple information tiers (first information tier with fault category code, second information tier with cross-device error code, third information tier with device-specific error code). This segmentation allows hierarchical processing where critical fault categories are communicated first, enabling rapid response while reducing the immediate communication burden compared to transmitting all detailed information simultaneously.
Solution Approach 2:
The health code acts as an intermediary data structure that encapsulates fault information in a standardized format. This intermediary enables efficient communication between diverse vehicle components and the central processing system, reducing communication overhead by providing a universal interface rather than requiring custom communication protocols for each component type.
2Measurement precision
If multiple tiers of fault information are included in health codes, then measurement precision of fault conditions is improved, but loss of time in processing and transmitting codes increases
Solution Approach 1:
Fault information is divided into hierarchical tiers where the first tier (fault category code) provides immediate coarse-grained classification for rapid response, while subsequent tiers (cross-device error code, device-specific error code) provide progressively more detailed information. This allows the system to process critical information quickly while having detailed information available for later analysis, resolving the time-precision tradeoff.
Solution Approach 2:
The health code structure is prepared in advance with predefined tiers of information organization. When a fault occurs, the component can immediately populate and broadcast the health code without needing to structure the information at the moment of fault detection, reducing processing time while maintaining comprehensive information detail.
3Extent of automation
If fault detection algorithms are executed by individual vehicle components, then automation extent is improved, but device complexity of each component increases
Solution Approach 1:
Vehicle components are designed to autonomously execute detection algorithms and self-identify fault conditions without requiring external monitoring systems. Each component independently generates health codes and broadcasts them on communication networks, enabling distributed self-service fault detection that increases automation while keeping individual component complexity manageable through standardized interfaces.

AI summary
Described herein are systems, methods, and non-transitory computer-readable media for self-detection of a fault condition by a vehicle component, generation of a device health code that includes multiple tiers of information relating to the fault condition experienced by the vehicle component, and broadcasting of the device health code to one or more other vehicle components via one or more vehicle communication networks. A recommended vehicle response measure indicated by a reaction code in the device health code can then be taken or alternate vehicle response may be selected and initiated based on an evaluation of current vehicle operational data.
