Selective Data Transmission for Non-Railbound Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting data to non-railbound vehicles result in high resource usage and privacy concerns due to the need for vehicles to receive and process large volumes of irrelevant data, as all data must be initially received and stored before filtering, and current solutions do not adequately protect user privacy.
Innovation Solution
A method that selectively transmits data relevant to a vehicle's geographical region by first identifying the region, requesting specific data from a transmitter, and using anonymization services and dynamic region sizing to minimize data transmission and protect privacy, including the use of unique identifiers and multicast transmissions for grouped receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all external data are transmitted to every vehicle in a geographical region, then complete data coverage is achieved, but data transmission volume and resource usage increase significantly
Solution Approach 1:
The geographical region is divided into multiple segments based on vehicle locations and routes. Data are transmitted selectively to specific segments rather than broadcasting to all vehicles, reducing overall data transmission volume while maintaining complete coverage for vehicles that need the data.
Solution Approach 2:
Different data transmission strategies are applied to different geographical regions based on local conditions. Regions with high vehicle density or important routes receive targeted data transmissions, while other regions receive minimal or no transmissions, optimizing resource usage while ensuring reliability where needed.
2Reliability
If data are received and stored by all vehicles before filtering, then data availability is ensured, but processing resources and time are consumed
Solution Approach 1:
Data are filtered and processed on the server side before transmission to vehicles. The server identifies which data are relevant to which vehicles based on their locations, routes, and profiles, pre-processing the data so that vehicles receive only what they need without requiring extensive local filtering resources.
Solution Approach 2:
Only the necessary and relevant data are extracted from the complete dataset and transmitted to each vehicle. The server identifies and extracts specific data items that are relevant to individual vehicles based on their geographical region and route information, eliminating the need for vehicles to process irrelevant data.
3Loss of information
If precise vehicle identification and location tracking are implemented for targeted data transmission, then data relevance is improved, but privacy protection is compromised
Solution Approach 1:
A server acts as an intermediary between the data source and vehicles. The server handles all identification, location tracking, and data relevance determination, while vehicles only receive the filtered data without exposing their precise locations or identification information to the data source or other vehicles.
Solution Approach 2:
The server creates and uses copies of vehicle identification and location information for matching purposes, without requiring vehicles to transmit their actual sensitive data. Virtual representations are used to determine data relevance while protecting actual privacy-sensitive information.

AI summary
A method for selectively transmitting data from a transmitter to a receiver in a non-railbound land vehicle comprises, at the receiver end, selecting at least one geographical region. In this case, a geographical region corresponds to a limited area on a map. After the at least one region has been selected, a request is transmitted to the transmitter to transmit data relating to the at least one selected geographical region, and finally a data transmission initiated by the transmitter in response to the request is received. The data relating to the at least one selected geographical region contain, in particular, information relating to a traffic route infrastructure in the geographical region, which information is valid for a limited period or for a longer time.
