Vehicle-to-Vehicle Sensing for Non-V2X Traffic Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
V2X vehicles face challenges in detecting and adapting to non-V2X vehicles due to communication limitations, leading to potential safety issues and inefficiencies in traffic flow, as they cannot share information or coordinate movements with vehicles that are not equipped for wireless communication.
Innovation Solution
A method where a V2X vehicle receives surrounding information from another V2X vehicle about the presence, location, and speed of non-V2X vehicles within its detection range, allowing it to adjust its movement and communication protocols to ensure safety and efficiency, even when direct communication with the non-V2X vehicle is not possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X vehicles use wireless communication to share information about surrounding vehicles, then safety and traffic flow efficiency are improved, but the system becomes unable to detect or coordinate with non-V2X vehicles that lack communication capabilities
Solution Approach 1:
The patent employs sensors (cameras, radar, LIDAR) as intermediary detection mechanisms to identify non-V2X vehicles that cannot communicate wirelessly. These sensors act as mediators between the V2X communication system and traditional vehicles, enabling the V2X vehicle to perceive and respond to the presence of non-communicating vehicles in its environment, thereby resolving the contradiction between communication-based safety and detection versatility
2Productivity
If V2X vehicles rely on direct wireless communication with all surrounding vehicles, then coordination and traffic efficiency are enhanced, but the system fails when encountering vehicles without communication equipment
Solution Approach 1:
The patent implements a hybrid approach where V2X vehicles perform partial wireless communication coordination with equipped vehicles and supplement this with sensor-based detection and classical collision avoidance algorithms for non-V2X vehicles. This partial application of communication technology combined with traditional methods enables the system to maintain traffic flow efficiency while adapting to vehicles without communication capabilities
3Adaptability or versatility
If V2X vehicles implement comprehensive sensor detection for non-V2X vehicles, then detection capability is improved, but energy consumption and system complexity increase
Solution Approach 1:
The patent employs dynamic sensor activation strategies where sensors are activated selectively based on communication detection results. When wireless communication indicates the presence of V2X-equipped vehicles, communication protocols are used for coordination. When communication fails or is unavailable, sensor detection is activated to identify and respond to non-V2X vehicles, thereby reducing overall energy consumption while maintaining detection capability
