V2X Priority Messaging for Equal-Priority Vehicle Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-everything (V2X) technologies fail to address the game problem of vehicles with the same passing priority and do not effectively handle situations where vehicles with lower passing priority cannot complete driving tasks for a long time, leading to poor user experience.
Innovation Solution
An information transmission method where a first vehicle sends a message to a V2X device, including its passing priority level and related information, enabling the V2X device to make decisions based on the vehicle's passing priority, thereby resolving conflicts and improving collaboration efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicle-road collaboration is based solely on traffic rules passing priority, then the collaboration decision is simple and fast, but vehicles with the same passing priority cannot resolve conflicts and vehicles with lower priority cannot complete tasks timely
Solution Approach 1:
The patent segments the passing priority into multiple levels: traditional traffic rule-based priority and task-based priority. By dividing the priority determination into different dimensions (traffic rules + task urgency + waiting time), the system resolves conflicts among vehicles with the same traditional priority without increasing overall system complexity excessively.
Solution Approach 2:
The patent introduces dynamic priority adjustment where vehicles can change their priority level based on task completion status and waiting time. The passing priority is not fixed but dynamically updated during the collaboration process, allowing lower-priority vehicles to advance when their tasks are more urgent or when they have waited longer.
2Ease of operation
If vehicles continuously send collaboration requests without priority differentiation, then all vehicles have equal opportunity to collaborate, but the system becomes inefficient and vehicles with lower priority wait indefinitely
Solution Approach 1:
The patent implements feedback mechanisms where vehicles receive responses to their collaboration requests, and their priority level is adjusted based on the feedback and waiting time. This feedback loop ensures that vehicles with lower initial priority can still complete tasks by demonstrating urgency through extended waiting periods, while preventing indefinite waits through systematic priority updates.
3Adaptability or versatility
If the system only considers traffic rules for passing priority, then the implementation is simple and compliant with existing regulations, but it cannot solve game problems among equal-priority vehicles or ensure timely task completion for lower-priority vehicles
Solution Approach 1:
The patent merges traditional traffic rule-based priority with task-based priority into a unified passing priority determination system. By combining these two aspects, the system maintains compliance with existing traffic regulations while adding the capability to handle complex scenarios involving multiple equal-priority vehicles and urgent tasks, thereby enhancing adaptability without excessive complexity.
