Vehicle Telematics Data Sharing via Peer-to-Peer Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many vehicles lack onboard longer-range data communication services like cellular modems, making it difficult and costly for them to access telematics data, while vehicles with such services often have underutilized connections, creating an opportunity for peer-to-peer data sharing.
Innovation Solution
A system where vehicles without cellular telematics can request and obtain data from nearby vehicles with cellular capabilities, using direct wireless communication and predefined pricing parameters, allowing for on-demand data sharing and cost-effective access to telematics services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles include onboard cellular modems and data services, then data accessibility is improved, but vehicle cost increases
Solution Approach 1:
Vehicles with cellular capabilities autonomously provide data services to nearby vehicles that lack such capabilities. The servicing vehicle detects data requests from neighboring vehicles and automatically fulfills them using its own cellular connection, eliminating the need for requesting vehicles to have their own expensive onboard modems.
Solution Approach 2:
The cellular communication system in a vehicle serves dual purposes: it provides data services to the vehicle's own systems and simultaneously serves as a shared resource for neighboring vehicles. This multi-functionality allows a single cellular modem to benefit multiple vehicles, reducing overall system cost.
2Reliability
If vehicles include onboard cellular modems for data services, then data transfer capability is improved, but affordability for lower-end models deteriorates
Solution Approach 1:
Vehicles equipped with cellular modems independently provide data services to lower-end vehicles without requiring those vehicles to purchase expensive onboard communication hardware. The servicing vehicle uses its own cellular connection to fulfill data requests, making telematics services affordable for budget vehicles.
Solution Approach 2:
Vehicles with cellular capabilities act as intermediary nodes between the cellular network and vehicles without modems. They receive data requests from lower-end vehicles, fetch the required data through their own cellular connections, and relay it to the requesting vehicles, enabling affordable access to data services.
3Device complexity
If vehicles use shorter range communication like BLUETOOTH, then vehicle cost is reduced, but data communication reliability deteriorates
Solution Approach 1:
Vehicles with cellular capabilities serve as intermediary bridges between BLUETOOTH communication and remote data sources. Lower-end vehicles use their inexpensive BLUETOOTH modules to communicate with nearby vehicles that have cellular modems, which then handle the long-range data retrieval, combining the advantages of both communication methods.
Solution Approach 2:
The data communication function is segmented into two parts: local vehicle-to-vehicle communication using inexpensive BLUETOOTH for short-range data exchange, and remote cellular communication handled by neighboring vehicles with modems. This segmentation allows each vehicle to use only the communication technology it needs, optimizing cost and reliability.
4Reliability
If vehicles share data services peer-to-peer, then data accessibility for lower-end vehicles is improved, but pricing and transaction management complexity increases
Solution Approach 1:
The system implements automated feedback loops where vehicles broadcast their cellular availability status, receiving vehicles detect and request services, and servicing vehicles automatically fulfill requests and charge fees. This automated feedback mechanism manages the complexity of peer-to-peer service sharing without requiring manual intervention.
Solution Approach 2:
Vehicles autonomously manage the complexity of data sharing transactions by automatically detecting service requests, determining pricing based on predefined parameters, executing data transfer, and handling billing. This self-service approach eliminates the need for centralized management systems while managing transaction complexity.
Data Source
AI summary
Onboard need for data is determined based on a vehicle process requesting data. A request for the data is wirelessly communicated directly to other vehicles in local wireless communication. A price for the data is negotiated, and the data is received, responsive to sending an agreement to pay the negotiated price.
