Authenticated Accident Reporting for Multi-Vehicle Emergency Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency notification systems face challenges in accurately and promptly transmitting information during multi-vehicle accidents due to overlapping and redundant data from multiple devices, leading to communication bandwidth overload and complexity in distinguishing information at the emergency center.
Innovation Solution
A vehicle and emergency notification system that includes a determination unit to identify multiple-person accidents, performs vehicle-side and portable device-side authentication to verify driver ownership, collects and sorts personal data from involved vehicles, and instructs a designated portable device to send optimized information to the emergency center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information from all vehicles involved in an accident is transmitted to the emergency notification center, then the completeness of accident information is improved, but the communication bandwidth load and processing complexity increase
Solution Approach 1:
The patent extracts and identifies only the necessary accident information from multiple vehicles using authentication units and information generation units, rather than transmitting all data. The system extracts relevant personal data and accident details while filtering out redundant information, thereby reducing the burden on emergency notification centers while maintaining information completeness.
Solution Approach 2:
The system segments the information transmission task by designating one specific portable device as the information transmission target among multiple vehicles. This segmentation divides the complex multi-vehicle communication problem into manageable parts, with one device responsible for transmitting consolidated accident information to the emergency center.
2Reliability
If multiple portable devices send accident information simultaneously, then the reliability of information transmission is improved, but the communication bandwidth consumption increases
Solution Approach 1:
Instead of having multiple devices transmit information simultaneously to ensure reliability, the system inverts the approach by selecting one authenticated portable device to transmit information. The authentication unit verifies device legitimacy, and the selected device consolidates and transmits all necessary accident information, achieving reliability through authentication rather than redundancy.
3Measurement precision
If all personal data from involved vehicles is collected and transmitted, then the accuracy of emergency response is improved, but the data privacy protection becomes more difficult
Solution Approach 1:
The system applies local quality by selectively collecting and transmitting only the specific personal data necessary for emergency response from each vehicle. The information generation unit identifies and extracts only relevant accident-related information rather than all personal data, thereby maintaining response accuracy while minimizing privacy exposure through targeted data selection.

AI summary
A vehicle includes a determination unit, an authentication unit, a collector, an information generator, and a control processor. The determination unit determines whether multiple persons have been involved in an accident. The authentication unit performs vehicle-side possessor authentication to authenticate whether a portable device authenticated by portable device-side possessor authentication as is portable device owned by a driver. When the multiple persons have been involved in the accident and the portable device authenticated by the portable device-side possessor authentication corresponds to a portable device that is to send accident information to an emergency notification center, the collector collects information relevant to the accident from other vehicles involved in the accident. The information generator sorts out the information relevant to the accident to generate the accident information. The control processor causes the portable device authenticated by the portable device-side possessor authentication to send the accident information to the emergency notification center.
