Non-OBU Vehicle Warning Terminals Using Server-Mediated V2V Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles without an onboard unit (OBU) device cannot perform vehicle-to-vehicle (V2V) communication, limiting the implementation of applications like collision early-warning and reducing traffic accidents and efficiency.
Innovation Solution
A non-OBU onboard terminal sends vehicle information to a server, which generates early-warning information based on this data and sends it back to the terminal, enabling vehicles without an OBU to receive and act on collision warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an OBU device is installed to enable V2V communication, then collision early-warning capability is improved, but device complexity and cost increase for vehicles without OBU
Solution Approach 1:
The patent introduces a server as an intermediary component that receives vehicle information from non-OBU terminals and generates early-warning information. This mediator enables V2V communication functionality without requiring complex OBU devices in each vehicle, resolving the contradiction between reliability and device complexity by centralizing the communication logic.
Solution Approach 2:
The patent creates a simplified version of V2V communication functionality by using a non-OBU terminal that sends vehicle information to a server, which then generates and returns early-warning information. This copying approach replicates the essential safety functionality without requiring the full OBU device infrastructure.
2Productivity
If V2V communication is implemented using OBU devices, then traffic efficiency is improved, but accessibility is reduced for vehicles without OBU installation
Solution Approach 1:
The patent creates a universal solution where the server acts as a common platform that can serve both OBU-equipped vehicles and non-OBU vehicles. The server receives information from various sources and provides early-warning services to all vehicle types, making the system adaptable to different vehicle configurations and improving overall accessibility.
Solution Approach 2:
The server serves as a mediator that enables communication between vehicles regardless of whether they have OBU devices. By centralizing the communication logic and early-warning generation on the server side, the system becomes accessible to all vehicles through simple terminal devices, greatly improving adaptability while maintaining traffic efficiency benefits.
3Adaptability or versatility
If a server-based system is used for non-OBU vehicles, then accessibility is improved, but information processing time may increase compared to direct OBU-OBU communication
Solution Approach 1:
The system performs preliminary actions by having vehicles continuously send their information to the server, which pre-processes and stores this data. When early-warning scenarios are detected, the server can quickly generate and return alerts because the baseline information is already available, reducing the effective processing time for critical warnings.
Solution Approach 2:
The server implements a feedback mechanism where it continuously monitors vehicle information and automatically generates early-warning alerts when collision risks are detected. This closed-loop feedback system ensures that warnings are generated and returned to non-OBU terminals in real-time, minimizing information processing delays while maintaining high accessibility.
Data Source
AI summary
An information interaction method, a server, a non-OBU onboard terminal, and a storage medium. The information interaction method comprises: a server acquires at least two pieces of vehicle information, wherein at least one piece of vehicle information comes from a non-OBU onboard terminal (S100); the server generates vehicle early-warning information according to the at least two pieces of vehicle information (S200); and the server sends the vehicle early-warning information to the non-OBU onboard terminal, so that the non-OBU onboard terminal pushes early-warning notification information according to the vehicle early-warning information (S300).
