Vehicle Data Relay via Intermediary V2V Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy systems are inadequate for handling the high volume and time-sensitive data uploads required by automated vehicle fleets, as they often lack sufficient capacity and coverage for efficient data transmission.
Innovation Solution
A method where a first vehicle transmits its data package to a second vehicle within communication range, which then relays it to a central electronic computing device via an access point, utilizing direct communication such as V2V or D2D, and prioritizes data based on time restrictions and upload capacity, ensuring efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is uploaded via mobile network, then coverage is provided, but data transmission speed and volume are limited
Solution Approach 1:
The patent introduces a second vehicle as an intermediary carrier to receive data packages from the first vehicle via V2V communication and relay them to the central system through wireless LAN access point. This mediator approach enables the first vehicle to upload large volumes of data efficiently by leveraging the second vehicle's proximity to high-speed access points, overcoming the limitations of mobile network bandwidth.
2Quantity of substance
If legacy systems are used, then system simplicity is maintained, but data upload capacity and coverage are insufficient
Solution Approach 1:
The patent segments the data upload task across multiple vehicles, where the first vehicle generates data packages and the second vehicle acts as a relay. This segmentation allows the system to handle large data volumes by distributing the upload function across different vehicles, each performing a specific role in the data transmission chain.
Solution Approach 2:
The patent makes vehicles serve multiple functions: they act as both data generators and data carriers. The second vehicle not only performs its primary transportation function but also serves as a mobile data relay station, enabling it to help other vehicles upload data when in proximity to access points, thus providing multi-functionality without requiring dedicated upload infrastructure.
3Loss of time
If direct mobile network upload is used, then system operation is simple, but time restrictions for data delivery cannot be met
Solution Approach 1:
The patent implements preliminary action by having the central system evaluate vehicle routes in advance and identify suitable relay vehicles before data upload is needed. The system determines which vehicles will be in proximity to access points during specific time windows, allowing it to proactively assign data relay tasks and ensure timely delivery of time-sensitive data packages.
Solution Approach 2:
The patent incorporates feedback mechanisms where vehicles report their locations and route information to the central system, which then uses this information to dynamically assign data relay tasks. The central system continuously monitors vehicle positions and adjusts data upload assignments based on real-time feedback, ensuring that data is routed through the most efficient available paths to meet delivery deadlines.
