Vehicle Position Sharing via Inter-Vehicle Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems receive excessively large amounts of position information from vehicles, overwhelming the server with unnecessary data.
Innovation Solution
A communication system where vehicles in a following relationship transmit only inter-vehicle distance information to the server, and the server calculates the position of trailing vehicles based on the leading vehicle's position and distance, reducing the amount of data transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the server receives absolute position information from all vehicles, then the server has complete position data, but the amount of information becomes excessively large
Solution Approach 1:
The patent extracts only the necessary position information (absolute position of leading vehicle and inter-vehicle distance) while excluding redundant information (absolute position of following vehicles). This extraction approach maintains position data completeness for traffic management purposes while significantly reducing the total information volume transmitted to the server.
Solution Approach 2:
The patent introduces an intermediary calculation approach where the server computes following vehicle positions indirectly by combining the leading vehicle's absolute position with the inter-vehicle distance measurement. This intermediary method eliminates the need for direct position transmission from following vehicles while preserving position information accuracy.
2Loss of information
If following vehicles transmit absolute position information, then position data is complete, but data transmission volume increases
Solution Approach 1:
The patent extracts only essential position information from following vehicles (inter-vehicle distance) while omitting redundant absolute position data. This selective extraction maintains sufficient position information for traffic management while reducing the energy consumption associated with transmitting complete position data from all vehicles.
3Quantity of substance
If the server calculates position based on inter-vehicle distance, then data load is reduced, but calculation complexity increases
Solution Approach 1:
The patent introduces an intermediary calculation framework where the server processes position information by combining simple absolute position data with inter-vehicle distance measurements. This intermediary approach transforms complex position calculation tasks into straightforward arithmetic operations, reducing server calculation complexity while maintaining data load reduction benefits.

AI summary
The communication system includes a plurality of vehicles including a first vehicle and a second vehicle, and a server capable of communicating with the plurality of vehicles. When the second vehicle is traveling in the following relationship with the first vehicle, the first vehicle transmits the absolute position information of the first vehicle including the coordinate values of the latitude and longitude at which the first vehicle is located and the inter-vehicle distance information of the second vehicle to the server. The second vehicle does not transmit the absolute position information of the second vehicle to the server. The server calculates the absolute position of the second vehicle based on the absolute position information of the first vehicle and the inter-vehicle distance information of the second vehicle.
