Base-Station Cluster Departure Detection for Vulnerable Road Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication systems do not effectively protect vulnerable road users, particularly those who have left the cluster, due to high power consumption and sensitivity to computational processing limitations.
Innovation Solution
A method for protecting vulnerable road users through infrastructure/network communication that is less sensitive to power consumption and has excellent computational processing capability, utilizing cluster formation and departure detection methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device-based V2X communication is used to protect vulnerable road users, then protection capability is improved, but power consumption increases and computational processing limitations are exposed
Solution Approach 1:
The patent introduces an infrastructure (base station/network) as an intermediary to perform cluster management and departure detection. Instead of requiring vulnerable road users to autonomously manage clusters and detect departures using their own computational resources, the infrastructure collects location information and performs the detection centrally, thereby reducing the energy consumption and computational burden on mobile devices.
2Reliability
If device-based V2X communication is used to protect vulnerable road users, then protection capability is improved, but sensitivity to computational processing limitations increases
Solution Approach 1:
The infrastructure acts as a mediator that handles complex computational tasks such as cluster formation, member tracking, and departure detection. This centralizes the computational processing at the network side, reducing the complexity requirements for mobile devices while maintaining effective protection capabilities.
3Adaptability or versatility
If general device communication is used for vulnerable road users, then mobility is maintained, but protection effectiveness decreases for users who have left the cluster
Solution Approach 1:
The system continuously monitors location information of vulnerable road users and provides feedback about cluster status and departure events. When a user leaves the cluster, the infrastructure detects this change and can trigger appropriate protection responses, ensuring that protection effectiveness is maintained even when users are mobile or temporarily detached from the cluster.

AI summary
According to at least one embodiment, a method and apparatus for detecting a vulnerable road user or a terminal of the vulnerable road user that deviates from a cluster are disclosed. A base station detects the deviation of a second terminal from the cluster on the basis of a safety message received from a first terminal, and transmits a warning message to at least one of a peripheral terminal and a traffic control center. The first terminal and the second terminal are included in the same cluster, the safety message includes at least one of cluster information associated with the mobility of the cluster and user information associated with the mobility of the first terminal, and the warning message includes deviation information association with the second terminal.
