Vehicle Data Control System for Reducing Transmission Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for data acquisition from multiple vehicles transmit redundant and unnecessary data, leading to inefficiencies and inaccuracies, particularly due to varying accuracy requirements among applications and transmission errors.
Innovation Solution
A method that involves a communication unit, data receivers, and applications to anonymize and reduce data transmission by using a coded vehicle identification and allocated identifiers, allowing for precise data management and transmission only when vehicles are within specific regions, ensuring data protection and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data are transmitted from multiple vehicles to backend services, then data availability for applications is improved, but data redundancy and transmission volume increase
Solution Approach 1:
The patent extracts and transmits only the essential data elements required by backend services, filtering out redundant information. Data receivers identify and transmit only necessary data packets containing specific information needed for weather, traffic, or other location-based services, thereby reducing overall transmission volume while maintaining data availability.
Solution Approach 2:
The patent implements location-based data transmission where data are sent only when vehicles are within specific geographic regions of interest. This regional filtering ensures that data transmission occurs locally only when relevant, reducing unnecessary long-distance or irrelevant data transmissions while maintaining availability for targeted applications.
2Measurement precision
If high accuracy data are transmitted for all applications, then measurement precision is improved, but data transmission complexity increases
Solution Approach 1:
The patent implements dynamic data transmission where the accuracy and detail level of transmitted data adapt based on application requirements and vehicle location. Data receivers adjust the precision and granularity of transmitted information dynamically, sending high-accuracy data only when necessary and lower-accuracy aggregated data otherwise, thereby managing complexity while maintaining required precision.
Solution Approach 2:
The patent changes data transmission parameters such as accuracy level, sampling rate, and detail granularity based on specific application needs and contextual factors. By adjusting these parameters dynamically, the system transmits appropriately precise data without the overhead of always transmitting maximum-accuracy information, reducing management complexity.
3Measurement precision
If vehicle identification data are transmitted with location information, then data accuracy for specific positions is improved, but data protection requirements become more stringent
Solution Approach 1:
The patent introduces an intermediary processing layer that handles vehicle identification and location data. Instead of transmitting raw identification data directly with location information, the system uses intermediate processing to anonymize or aggregate identification data while preserving location accuracy, thereby reducing data protection risks while maintaining position precision for service delivery.
Data Source
AI summary
A method for controlling data acquired from vehicles, wherein case data are anonymized and provides data reduction. Control exists between the units of each vehicle, between the vehicles and a backend of the system, between the units of the backend, and also between the units of the backend and at least one external service provider. The data are reduced by avoiding the transmission of redundant data or by avoiding unnecessary data acquisition.
