Vehicle Data Delivery Consolidation for Bus Overload Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of vehicle data requests leads to redundant data collection, causing on-vehicle bus overload and inefficient cellular data usage due to multiple requests for the same data, resulting in potential data loss and wasteful data delivery.
Innovation Solution
A Splice-on Glue-off (SoGo) system is implemented on vehicles to receive new data request configurations, identify individual data elements, and provide instructions for compiling these elements, which are then sent to a cloud server for storage, thereby minimizing redundant data collection and optimizing data delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple diagnostic data requests are sent to vehicles, then comprehensive data coverage is improved, but redundant data collection increases bus load and cellular data usage
Solution Approach 1:
The patent combines multiple diagnostic data requests into a single consolidated data collection process. The vehicle receives multiple diagnostic configurations from different requester devices, identifies redundant data elements, and collects each unique data element only once during a single vehicle visit. This merging approach maintains comprehensive data coverage while eliminating redundant data collection, thereby reducing on-vehicle bus load and cellular data usage.
Solution Approach 2:
The system creates a universal data collection mechanism that serves multiple requester devices simultaneously. A single diagnostic data collection event generates data that can satisfy multiple different diagnostic requirements, making the data collection process multi-functional. This allows the system to adapt to various diagnostic needs without performing separate data collection operations for each requester.
2Reliability
If diagnostic data is collected frequently to meet multiple configuration requirements, then data availability is improved, but on-vehicle bus overload increases
Solution Approach 1:
The patent merges multiple diagnostic data collection operations into a single unified collection event. By identifying all required data elements across multiple configurations and collecting them in one pass during a vehicle visit, the system ensures data availability for all requester devices while preventing bus overload that would result from multiple separate collection attempts.
3Reliability
If redundant data collection is performed to satisfy multiple diagnostic configurations, then complete data delivery is improved, but cellular data usage efficiency deteriorates
Solution Approach 1:
The system consolidates multiple data delivery operations by collecting and transmitting each unique data element only once, even when multiple requester devices require the same data. This merging of delivery operations ensures complete data availability for all requesters while eliminating redundant cellular data transmissions, thereby improving energy efficiency.
Solution Approach 2:
The patent creates a single master copy of diagnostic data during one collection event, which can then be distributed to multiple requester devices. Instead of collecting and transmitting data separately to each requester, the system generates one authoritative copy that serves all downstream needs, eliminating redundant cellular data usage while ensuring data completeness.
4Adaptability or versatility
If multiple separate data collection operations are performed, then specific data requirements are met, but data collection time and processing overhead increase
Solution Approach 1:
The patent merges multiple separate data collection operations into a single integrated collection process. By identifying all required data elements across multiple diagnostic configurations beforehand, the system collects all necessary data in one operation during the vehicle visit, thereby satisfying all data requirements while minimizing data collection time and processing overhead.
Data Source
AI summary
From diagnostic configurations, individual data elements and a frequency for collection of each data element including removing redundant collection of data elements are identified. Diagnostic data from the vehicle in accordance with the identification are periodically collected. The diagnostic data is sent to the server with instructions that specify each data element in the diagnostic data and for which configurations each data element in the diagnostic data is required.
