Vehicle Route Data Transmission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles transmit a large amount of redundant data, requiring significant storage and processing capabilities and bandwidth, which is inefficient and costly, as much of the data is recurrent and unnecessary.
Innovation Solution
A method that determines a frequently used reference route and compares new routes to this reference, transmitting only new data and deleting redundant data associated with repeated reference routes, thereby reducing the amount of data transmitted and processed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all vehicle data are transmitted to communication equipment, then complete data analysis is possible, but transmission bandwidth is excessively consumed and storage requirements become very large
Solution Approach 1:
The patent extracts and transmits only the essential route definition data (geographical coordinates, timing information) while eliminating redundant vehicle operation data that can be locally cached and reconstructed. This extraction principle reduces transmitted data volume while preserving the ability to perform complete route-based analysis.
Solution Approach 2:
The system performs preliminary local processing by identifying and caching route definitions within the vehicle before transmission. By pre-identifying which data constitutes route definition versus redundant data, the system prepares the data structure in advance to enable efficient filtering and reduce transmission requirements.
2Measurement precision
If route definition data are transmitted for every new route, then accurate route tracking is achieved, but transmission frequency increases and bandwidth is wasted on redundant transmissions
Solution Approach 1:
The communication equipment provides feedback by storing transmitted route definitions and using them to identify subsequent routes. This feedback mechanism allows the system to recognize when a route has been previously transmitted and avoid redundant transmissions, thereby improving transmission efficiency while maintaining accurate route tracking through intelligent comparison.
3Duration of action of stationary object
If vehicle data are stored for extended periods to cover selected time periods, then complete historical analysis is possible, but storage capacity requirements become very large and costly
Solution Approach 1:
The system extracts only the essential route definition characteristics needed for historical analysis while eliminating redundant detailed vehicle operation data. By storing only the extracted route identifiers and essential parameters rather than complete raw data, the system achieves long-term historical coverage with significantly reduced storage capacity requirements.

AI summary
A method is dedicated to controlling data transmission by waves from a vehicle (V) to communication equipment (EC), and comprises a first step in which the most frequently taken reference route is determined in the vehicle (V) for a selected duration, then a definition of this reference route is transmitted, and a second step, in which each new route taken is compared, in the vehicle (V), to the reference route, and, in the event of a difference, a definition of this new route is transmitted with predefined data of the vehicle (V) that is recorded during this new route, whereas in the event of identity, information is transmitted that represents the fact that the reference route has been taken again and the predefined data of the vehicle (V) recorded during the reference route that has been taken again is deleted in the vehicle (V).
