Vehicle Route Data Segmentation for Transmission Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods for vehicles, such as aircraft, transmit unnecessary data for already-traveled portions of a route, leading to inefficiencies and inconvenience, as they often require large and costly data transfers that include irrelevant information.
Innovation Solution
A system and method that automatically requests and receives updated travel condition data only for the subset of the route ahead of the vehicle, using a communication device and processor to identify sub-routes based on the vehicle's position and user-defined distance, thereby minimizing data transmission to relevant areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is transmitted for the entire travel route, then complete route information is available, but data transmission size becomes unnecessarily large
Solution Approach 1:
The patent divides the travel route into multiple segments based on the vehicle's current position and a predetermined distance threshold. Instead of transmitting data for the entire route, the system segments the route and only requests data for the relevant forward segment, eliminating redundant data transmission for already-traveled portions.
Solution Approach 2:
The system extracts and requests only the necessary subset of route data that is relevant to the vehicle's current position and future travel needs. By filtering out already-traveled portions and requesting only the required segment, the patent reduces data transmission size while maintaining information completeness for decision-making.
2Loss of information
If manual data requests are implemented during travel, then data can be updated, but operational convenience deteriorates due to crew workload
Solution Approach 1:
The system implements automatic data requests that operate without manual intervention from the flight crew. The processor automatically determines when data requests are needed based on vehicle position and route information, eliminating the need for crew members to manually initiate data updates during flight operations.
Solution Approach 2:
The system continuously monitors the vehicle's position along the route and uses this feedback to automatically trigger data requests at appropriate moments. This closed-loop approach ensures data is updated timely based on actual travel progress without requiring manual input from the crew.
3Loss of information
If large data transmissions are performed, then comprehensive route data is received, but transmission cost and time increase
Solution Approach 1:
By segmenting the route into relevant and irrelevant portions, the system transmits only the necessary data segment forward of the vehicle's current position. This segmentation approach maintains comprehensiveness for decision-making while dramatically reducing transmission time and associated costs.
Solution Approach 2:
The system requests slightly more data than the minimum threshold by including a predetermined distance buffer ahead of the vehicle's current position. This partial action approach ensures sufficient data comprehensiveness for upcoming decisions while avoiding the excessive action of transmitting entire route data, thereby optimizing transmission time and cost.

AI summary
A method for obtaining updated travel condition data at a vehicle is provided. The method identifies a subset of a predetermined travel route that is ahead of the vehicle, based on a selected distance quantity and a current position of the vehicle during traveling; and requests a set of data for the subset, the updated travel condition data comprising the set of data.
