Temporary Vehicle Identification for Platoon Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle platoon communication systems face challenges in efficiently identifying vehicles during communication, which affects the coordination and security of vehicle platoons, particularly in reducing fuel consumption and CO2 emissions.
Innovation Solution
The implementation of a temporary vehicle identification license plate system, where vehicles within a platoon create and repeatedly update temporary identification plates for communication purposes, allowing for efficient local identification without the need for globally unique identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If globally unique vehicle identification numbers are used for communication, then vehicle distinguishability is improved, but communication efficiency and security are worsened due to longer identification data and unauthorized tracking risks
Solution Approach 1:
The patent divides the identification system into two segments: temporary identification numbers for platoon communication and permanent globally unique identification numbers for vehicle registration. The temporary identification numbers are segmented further into platoon-specific segments, allowing efficient local identification without requiring globally unique long identifiers in every communication message.
Solution Approach 2:
The patent applies local quality by creating identification numbers tailored to specific communication contexts. Within a platoon, vehicles use temporary identification numbers that are locally unique to that platoon rather than requiring globally unique identifiers. This local differentiation improves communication efficiency while maintaining sufficient identification accuracy for the specific context.
2Productivity
If temporary vehicle identification numbers are used, then communication efficiency is improved, but vehicle identification reliability is worsened due to frequent changes
Solution Approach 1:
The patent implements dynamic identification where temporary vehicle identification numbers are generated and updated periodically or when vehicles join/leave the platoon. This dynamic approach allows the system to adapt to changing platoon compositions while maintaining reliable communication. The receiving vehicles are notified of changes through platoon messages, ensuring identification consistency is maintained despite the dynamic nature of the identifiers.
3Stability of the object's composition
If permanent vehicle identification numbers are used, then identification stability is improved, but security against unauthorized tracking is worsened
Solution Approach 1:
The patent employs disposable temporary identification numbers that are valid only for specific platoons and time periods. These temporary identifiers are discarded when the platoon dissolves or when a vehicle joins a different platoon, preventing long-term tracking. The low cost and short lifespan of these identifiers compared to permanent ones provide security against unauthorized tracking while maintaining sufficient stability for active communication.

AI summary
The invention relates, inter alia, to a method for communication for operating a vehicle platoon (10). The method includes the creation of a temporary vehicle identification number (VIN) by a sender vehicle (14) of the vehicle platoon (10) and the creation of a platoon message (20) to the vehicle platoon (10) by the sender vehicle (14). The platoon message (20) contains the temporary VIN for identifying the sender vehicle (14) as the sender of the platoon message (20). The platoon message (20) is sent by the sender vehicle (14) to the vehicle platoon (10). The use of the temporary VIN can enable more efficient communication.
