Interactive I2V Broadcast System for Real-Time Vehicle Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Infrastructure-to-Vehicle (I2V) communication systems lack interactive capabilities, failing to respond to changing traffic situations and physical conditions of vehicles, which is critical for timely warnings and safety in areas like icy bridges or tunnels.
Innovation Solution
An interactive communication method and system that allows traffic participants to respond to broadcast messages from infrastructure communication stations, using a dedicated information structure with a request for response based on predetermined conditions, enabling quick reactions to hazardous situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional broadcast-based I2V communication system is used, then the infrastructure can transmit warning information to traffic participants, but the system cannot obtain real-time feedback or respond to changing traffic situations and vehicle conditions
Solution Approach 1:
The patent implements a feedback mechanism where traffic participants send response messages to the infrastructure communication station after receiving broadcast warnings. The response includes vehicle identification, position, and physical condition data. This feedback loop enables the infrastructure to adapt warnings based on real-time vehicle status, resolving the contradiction between reliable safety responses and interactive capabilities.
Solution Approach 2:
The system transitions from static one-way broadcasting to dynamic two-way communication. The infrastructure can adjust warning content and transmission parameters based on received feedback, making the system adaptive to changing traffic situations and vehicle conditions, thereby achieving both reliability and versatility.
2Loss of information
If the broadcast message contains detailed information for all traffic participants, then comprehensive safety information is provided, but the message size and processing complexity increase
Solution Approach 1:
The patent applies local quality by customizing broadcast message content based on receiver characteristics. The infrastructure determines which information elements to include based on the physical conditions and types of traffic participants in the localized area. This ensures each participant receives relevant safety information without unnecessary data, reducing message complexity while maintaining information completeness.
Solution Approach 2:
The broadcast message is segmented into different information elements that can be selectively included or excluded. The infrastructure divides comprehensive safety information into modular components and transmits only the relevant segments to each traffic participant based on their specific conditions, thereby reducing overall message complexity while preserving necessary safety information.
3Adaptability or versatility
If the system waits for vehicle responses before taking action, then interactive capabilities are enhanced, but the response time to hazardous situations is delayed
Solution Approach 1:
The infrastructure sends preliminary warning broadcasts to traffic participants before hazardous situations fully develop. These initial warnings are sent proactively based on detected conditions, allowing participants to prepare responses in advance. This preliminary action enables interactive capabilities without significantly delaying critical response times.
Solution Approach 2:
The system maintains continuous communication through periodic broadcasts and ongoing response exchanges. Rather than waiting for single discrete responses, the infrastructure continuously monitors traffic conditions and maintains active communication channels, ensuring that interactive capabilities are available without creating time delays in hazard response.
