Vehicle Data Recording and Intermittent Network Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle data communication systems face challenges in transmitting diagnostic data due to weight or connectivity limitations, especially in remote areas without stable internet connections, making it difficult to analyze usage patterns and improve vehicle operations effectively.
Innovation Solution
A system comprising a data recording device and a data transmitting device onboard the vehicle that stores diagnostic data and initiates communication with an independent data communication device only when a network connection is available, using devices like smartphones or IoT devices as intermediaries to relay data to a network for further analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle data is continuously transmitted in real-time, then data analysis capability is improved, but connectivity requirements increase and become unmet in remote areas
Solution Approach 1:
The system performs preliminary data storage in local memory before transmission is needed. Data is collected and stored during vehicle operation, then transmitted when connectivity becomes available. This eliminates the need for continuous real-time transmission while ensuring data is ready for analysis.
Solution Approach 2:
The patent introduces an intermediary data storage system between the vehicle sensors and the remote server. Data flows from sensors to local memory, then to transmission device, and finally to the server. This intermediary buffer decouples the transmission process from continuous connectivity requirements.
2Loss of information
If all vehicle data is stored for analysis, then data completeness is improved, but storage requirements and device complexity increase
Solution Approach 1:
The system extracts and stores only the essential diagnostic data needed for vehicle operation analysis. By selecting specific data parameters rather than storing all possible vehicle data, the system maintains data completeness for analysis while reducing storage requirements and simplifying the storage system.
Solution Approach 2:
The patent implements partial data storage by selecting only the most critical diagnostic parameters for retention. This partial action approach stores sufficient data for effective vehicle operation analysis without the excessive complexity of storing all possible vehicle data streams.
3Loss of information
If data transmission occurs continuously, then data availability for analysis is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous transmission, the system employs periodic batch transmission. Data is accumulated over time and transmitted in periodic intervals when connectivity is available. This periodic action maintains data availability for analysis while dramatically reducing the energy consumption associated with continuous transmission operations.
4Adaptability or versatility
If vehicle operates in remote areas without stable internet, then operational flexibility is improved, but data transmission capability deteriorates
Solution Approach 1:
The system performs preliminary data storage during vehicle operation in remote areas. Data is captured and held in local memory while the vehicle operates without stable internet connectivity. When connectivity becomes available, the pre-stored data is transmitted, thus maintaining both operational flexibility and transmission reliability.
Solution Approach 2:
The patent introduces an intermediary local storage system that decouples vehicle operation from data transmission requirements. This intermediary allows the vehicle to operate flexibly in remote areas while ensuring data can be reliably transmitted when connectivity is available.
Data Source
AI summary
A system, method and computer program product for communicating data of a vehicle. The system includes a data recording device and a data transmitting device coupled to the vehicle. The data recording device is configured to receive at least a vehicle datum during operation of the vehicle, determine a subset of the at least a vehicle datum to be stored, wherein the subset of data is stored during operation of the vehicle, and store the subset of the at least a vehicle datum as a stored vehicle data, wherein the stored vehicle data comprises a diagnostic datum of a vehicle component. The data transmitting device is configured to initiate communication with an independent data communication device as a function of a connection to a network and transmit the stored vehicle data to the independent data communication device as a function of the connection to the network.
