Intermediary Vehicle Data Relay for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of transmitting data from motor vehicles to a stationary data network, such as the Internet, due to the expense of cellular connections, limits the amount of data that can be exchanged, hindering the generation of map data for piloted driving functions and analysis of algorithms for object detection.
Innovation Solution
A method where a motor vehicle, referred to as the terminal vehicle, exchanges data packets with a base vehicle that has direct access to the data network, using a radio-based communication device, eliminating the need for a cellular connection and allowing data to be routed through intermediary vehicles if direct communication is not possible, utilizing a predetermined routing protocol to maximize successful and fast data packet transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted from motor vehicles to the stationary data network via cellular connection, then data can be exchanged with the Internet, but transmission costs increase significantly
Solution Approach 1:
The patent introduces intermediary vehicles (relay vehicles) that have direct Internet access to mediate data transmission between terminal vehicles and the stationary data network. Instead of every vehicle paying for cellular transmission, data is routed through intermediary vehicles that can transmit data more cost-effectively, reducing the overall transmission cost while maintaining data exchange capability.
Solution Approach 2:
The patent segments the data transmission path into multiple hops through different vehicles. Rather than a direct cellular connection from terminal vehicle to network, data is broken down into segments transmitted through intermediate vehicles, allowing cost distribution and optimization across the vehicle network.
2Productivity
If data transmission volume is increased to improve map data and algorithm analysis, then better piloted driving functions are achieved, but cellular connection costs become prohibitively expensive
Solution Approach 1:
Intermediary vehicles serve as cost-effective relay points that enable high-volume data transmission without proportional increases in cellular connection costs. By utilizing the network of intermediary vehicles, the system can transmit large amounts of data for map generation and algorithm analysis at reduced per-unit cost.
Solution Approach 2:
Vehicles in the network serve multiple functions: they act as both data sources and potential relay nodes. This multi-functionality allows the system to optimize data routing dynamically, selecting paths that minimize cellular connection usage while maintaining high data transmission volumes necessary for productivity improvements.
3Reliability
If direct cellular connection is used for data transmission, then communication reliability is maintained, but infrastructure requirements and operational costs increase
Solution Approach 1:
The patent reduces infrastructure dependency by introducing vehicle-based intermediaries that create alternative transmission paths. This mesh network approach provides redundancy and reduces reliance on centralized cellular infrastructure, maintaining communication reliability while decreasing infrastructure complexity and cost.
