Vehicle Emergency Rescue Data Segmentation for Accident Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eCall systems rely on minimal accident information, which is insufficient for accurately determining the severity of accidents and injuries, and drivers may be incapacitated to provide additional details.
Innovation Solution
A vehicle emergency rescue method and device that transmits standardized minimum accident information to a control center, connects an emergency call, and optionally provides extended accident information and images upon request, using sensors and communication protocols to enhance situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only minimum accident information is transmitted to the control center, then the system complexity is reduced and transmission speed is improved, but the accuracy of accident severity determination deteriorates
Solution Approach 1:
The information transmission is divided into two segments: first, minimum accident information (MSD) is transmitted immediately for basic emergency response; second, extended accident information is transmitted subsequently for detailed assessment. This segmentation allows the system to balance between quick response and accurate assessment without requiring all information to be transmitted simultaneously.
Solution Approach 2:
The minimum accident information is transmitted in advance before extended information is available. This preliminary action ensures that emergency services are activated immediately based on critical data, while additional information is gathered and transmitted later to improve assessment accuracy without delaying the initial emergency response.
2Measurement precision
If extended accident information is transmitted additionally, then the accuracy of injury assessment is improved, but the transmission time and system complexity increase
Solution Approach 1:
Information transmission is segmented into priority levels: critical minimum information is transmitted first for immediate injury assessment, while extended information is transmitted subsequently. This allows emergency services to begin response based on critical data while more detailed information continues to arrive, improving assessment accuracy without requiring complete information before action.
Solution Approach 2:
The system implements feedback mechanisms where the control center receives initial minimum information, processes it for immediate response, then receives additional extended information to refine the assessment. This feedback loop allows continuous improvement of injury severity determination accuracy while maintaining rapid initial response capability.
3Loss of information
If drivers are required to provide additional accident information through emergency call, then the completeness of accident information is improved, but the reliability of information provision deteriorates due to driver incapacitation
Solution Approach 1:
The vehicle system automatically collects and transmits extended accident information without requiring driver intervention. Sensors and onboard systems gather data about the accident, vehicle status, and potential injuries, and transmit this information automatically to the control center, eliminating the need for incapacitated drivers to provide information manually.
Solution Approach 2:
The system replaces the mechanical approach of manual driver reporting with automated sensor-based information collection. Physical sensors detect accident parameters, vehicle systems report status data, and communication systems automatically transmit information, substituting human driver action with automated mechanical and electronic systems that are reliable even when the driver is incapacitated.
