Geofenced Vehicle Warning Control for Real-Time 5G Safety Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles without advanced driver assistance systems (ADAS) lack safety and convenience functions, and existing communication technologies do not efficiently provide real-time data transmission for enhanced safety and convenience, especially in scenarios requiring rapid data exchange for autonomous driving.
Innovation Solution
A communication device that sets variable geofences based on road characteristics and vehicle information, transmitting customized warning messages to vehicles within specific areas to enhance safety and convenience, even in vehicles without ADAS, using 5G communication for ultra-wideband and real-time data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ADAS is installed in vehicles to provide safety and convenience functions, then safety and convenience are improved, but cost and complexity increase
Solution Approach 1:
The patent introduces a server as an intermediary that performs advanced safety functions remotely. The server receives vehicle information from multiple vehicles, processes it to detect events (collisions, anomalies), and transmits warnings to other vehicles. This mediator approach allows vehicles without ADAS to benefit from safety functions that would otherwise require complex onboard systems.
Solution Approach 2:
The system enables vehicles to provide safety services to each other through peer-to-peer information sharing. Each vehicle's sensors and communication systems are utilized to contribute to the collective safety of the network, allowing the system to serve itself without requiring every vehicle to have full ADAS capabilities.
2Loss of time
If data transmission between vehicles and servers is increased to enable real-time safety functions, then safety response time is improved, but communication bandwidth requirements increase
Solution Approach 1:
The patent extracts and transmits only the most critical information elements: vehicle position, speed, acceleration, and event detection results. By selecting and transmitting only essential data rather than complete sensor streams, the system achieves real-time response with minimized data volume.
Solution Approach 2:
The system applies different data transmission qualities to different vehicles based on their relevance to detected events. Vehicles near an event receive detailed warning information, while distant vehicles receive summarized or no information, optimizing bandwidth utilization across the network.

AI summary
A communication device includes: a communication unit receiving position information of each vehicle from vehicles located in a predetermined area; and a processor setting first and second geofences for the predetermined area, and controlling the communication unit to transmit a warning message related to an event to one or more vehicles located in the second geofence in response to the event occurring in the first geofence.
