Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication systems lack effective mechanisms for rapidly and directly sensing and responding to abnormal vehicle operations, such as driver fatigue or vehicle malfunctions, to prevent accidents and ensure road safety.
Innovation Solution
Implementing a method where driver status monitoring devices and surrounding vehicles use V2X communication to detect and announce abnormal vehicle statuses to surrounding vehicles and networks, enabling rapid intervention and control to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If abnormal operation information is transmitted to all surrounding vehicles and network, then response speed and accident prevention capability are improved, but information transmission complexity and network load increase
Solution Approach 1:
The system segments abnormal operation information into different priority levels and transmits them through appropriate channels. Critical safety information is transmitted immediately to all surrounding vehicles, while less urgent information is routed through network infrastructure, reducing overall transmission complexity while maintaining fast response for critical events
Solution Approach 2:
The system introduces network infrastructure and base stations as intermediaries to manage and route abnormal operation information. These intermediaries consolidate data from multiple sources, filter redundant information, and distribute only necessary alerts to specific vehicles, reducing network load and transmission complexity while maintaining rapid response capability
2Measurement precision
If driver status monitoring and vehicle sensing devices are deployed, then detection precision and abnormality identification are improved, but device complexity and system cost increase
Solution Approach 1:
The system uses multi-functional sensors that can detect multiple types of abnormal conditions simultaneously. For example, inertial measurement units detect both sudden braking and sharp turning, while cameras monitor both driver fatigue and pedestrian presence. This approach improves detection precision across multiple parameters without proportionally increasing device complexity
Solution Approach 2:
The system combines data from multiple sensing devices and processes them through integrated algorithms to identify abnormal operations. By merging information from driver status monitors, vehicle sensors, and environmental detectors, the system achieves high detection precision while managing complexity through unified processing architecture

AI summary
Presented in the present disclosure is a method by which a driver situation monitoring device or adjacent vehicles detect the situation of a driver and/or a vehicle in which an abnormality occurs while driving, and provide, through a V2X communication device, the information to the vehicle in which the abnormality has occurred and adjacent vehicles, networks or related organizations, and thus accidents can be prevented or a vehicle in which an abnormality occurs can be controlled.
