RSU-CCTV Driving Negotiation via Temporary Vehicle IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road side units (RSUs) are limited in their ability to cover all areas of the road for driving negotiations, and closed-circuit televisions (CCTVs) cannot participate in driving negotiations due to lack of supported message specifications, hindering smooth and safe vehicle communication.
Innovation Solution
A system and method that enables CCTVs to participate in driving negotiations by using temporary identification (ID) and encryption values, allowing RSUs to continue negotiations seamlessly across different areas without exposing unique vehicle IDs, ensuring privacy and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If RSUs are deployed to cover all areas of the road for driving negotiations, then the coverage area is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines RSUs and CCTVs into a unified driving negotiation system where CCTVs participate as equal infrastructure components. This merging allows the system to utilize existing CCTV infrastructure for negotiation purposes, extending coverage without deploying additional dedicated RSUs throughout all areas.
Solution Approach 2:
CCTVs are given multiple functions: they not only perform their traditional surveillance role but also actively participate in driving negotiations by transmitting vehicle identification information and negotiation data. This multi-functionality reduces the need for separate dedicated negotiation infrastructure in all areas.
2Reliability
If CCTVs are integrated into driving negotiations with full message specification support, then the negotiation safety and smoothness are improved, but the device complexity increases
Solution Approach 1:
The patent introduces a standardized message specification protocol that acts as an intermediary between CCTVs and RSUs. This protocol enables CCTVs to participate in driving negotiations without requiring direct complex integration, allowing them to exchange information through a common language that both systems understand.
3Measurement precision
If unique vehicle IDs are transmitted to RSUs for negotiation identification, then the identification accuracy is improved, but the loss of information related to vehicle privacy increases
Solution Approach 1:
Instead of transmitting actual unique vehicle IDs directly to RSUs, the system uses temporary IDs that are generated and exchanged during negotiations. These temporary IDs serve as copies or representations of the vehicle identity for negotiation purposes only, allowing accurate identification during the negotiation process while preventing permanent storage of sensitive vehicle privacy information.
Solution Approach 2:
The system performs preliminary actions by establishing temporary IDs before the actual negotiation takes place. These temporary IDs are prepared in advance and used throughout the negotiation process, ensuring that vehicle privacy is protected from the outset while still enabling accurate vehicle identification and continuous negotiation.
4Duration of action of moving object
If driving negotiations are continued across different areas with temporary IDs, then the negotiation continuity is improved, but the difficulty of detecting and measuring fraudulent requests increases
Solution Approach 1:
The patent implements feedback mechanisms where CCTVs and RSUs continuously verify the validity of temporary IDs and negotiation messages. The system provides feedback about the authenticity of communication partners, allowing participants to detect fraudulent requests by analyzing inconsistencies in the feedback information from various infrastructure components.

AI summary
A method according to an example embodiment of the present disclosure may comprise: when a vehicle being performing a driving negotiation moves, receiving, by an RSU, a first message including a first temporary identification (ID) of the vehicle from a first RSU on a past route of the vehicle; receiving, by the RSU, a second message including a second temporary ID of the vehicle identified by a closed-circuit television (CCTV) in a communicable area of the RSU from the CCTV; checking, by the RSU, the second temporary ID of the vehicle based on the second message received from the CCTV; and identifying, by the RSU, the vehicle as a target to extend the driving negotiation and performing the driving negotiation with the identified vehicle.
