Vehicle Control Association Messaging for Real-Time Traffic Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional transportation systems, vehicles lack effective communication with other traffic participants, leading to poor safety and efficiency, as they cannot exchange necessary information in real-time, resulting in potential accidents and delayed schedules due to lack of congestion or oncoming vehicle data.
Innovation Solution
A vehicle external communication method and apparatus that enables vehicles to establish and manage control associations with management devices, allowing for the exchange of information such as vehicle status, user updates, and resource allocation requests, enhancing interaction and coordination within the transportation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles do not exchange information with other traffic participants, then the system is simple and does not require complex communication protocols, but vehicle safety and passing efficiency deteriorate due to lack of real-time information about oncoming vehicles and congestion
Solution Approach 1:
The communication system is segmented into different message types (application request messages, application response messages, notification messages) and different association types (control association, notification association), allowing the system to handle specific communication needs without requiring a complete complex communication framework for all interactions
Solution Approach 2:
The patent implements partial action by providing different levels of association between vehicles and management devices - control association for full interaction and notification association for one-way information flow. This allows the system to establish communication only where necessary, reducing overall system complexity while maintaining safety where needed
2Reliability
If vehicles frequently interact with other traffic participants to improve safety and efficiency, then information exchange improves, but the quantity of information to be collected, processed, and exchanged increases significantly
Solution Approach 1:
Vehicle information is segmented into static information (vehicle model, load, emission) and dynamic information (direction, speed, braking), allowing the system to transmit only relevant portions rather than complete vehicle datasets, thereby reducing information quantity while maintaining safety
Solution Approach 2:
The system transmits partial information based on the type of association established - control association receives comprehensive information while notification association receives only essential alerts, reducing overall information quantity while maintaining necessary safety monitoring
3Productivity
If vehicles establish control association with management devices for real-time control, then vehicle scheduling and resource allocation improve, but the complexity of managing associations and messages increases
Solution Approach 1:
The association management is segmented into control association for active vehicles requiring real-time control and notification association for informational updates, allowing the system to manage different vehicle types with different communication needs separately, reducing overall management complexity
Solution Approach 2:
The system establishes partial associations only where needed - full control association for vehicles actively using transportation resources and simpler notification association for others, reducing association management complexity while maintaining productivity for active vehicles
Data Source
AI summary
A vehicle external communication method and apparatus and a terminal, where the method includes sending, by a vehicle, an association registration request message to a management device, where the association registration request message indicating that the vehicle requests to establish a control association with the management device, and receiving, by the vehicle, a first association registration response message from the management device including a success identifier, or receiving, by the vehicle, a second association registration response message from the management device including a failure identifier.
