Vehicle Accident Data Server for Secondary Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In situations where traffic accidents occur in sparsely populated areas or on highways, there is a challenge in promptly reporting the accident to passing vehicles, leading to potential secondary accidents due to lack of information about the incident.
Innovation Solution
A method and apparatus that utilize a communication device and processor to collect and process accident information from vehicles involved, including location and image data, to determine accident severity and transmit response instructions, such as detour routes, to following vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual reporting methods are used for traffic accidents in sparsely populated areas, then the system complexity is low, but the information transmission speed and accident reporting efficiency deteriorate
Solution Approach 1:
The system performs preliminary actions by automatically detecting accidents through sensors (accelerometers, gyroscopes) and pre-processing accident information before other vehicles arrive. The server proactively pushes accident notifications to following vehicles before they reach the accident scene, eliminating the need for manual reporting and ensuring timely warning transmission.
Solution Approach 2:
A cloud-based server acts as an intermediary between the accident vehicle and following vehicles. The server receives accident data from sensors, processes the information, and transmits warnings to following vehicles via V2X communication, enabling efficient information transmission without direct vehicle-to-vehicle contact and improving reporting efficiency while maintaining manageable system complexity.
2Measurement precision
If no automated accident detection system is deployed, then the device complexity remains low, but the accuracy and timeliness of accident information deteriorate
Solution Approach 1:
The system merges multiple detection functions into a unified accident detection module that combines accelerometer, gyroscope, and other sensor data. By integrating these detection capabilities into a single system that communicates with the server, the patent achieves high accident detection accuracy while avoiding the complexity of separate independent detection systems in each vehicle.
Solution Approach 2:
The accident detection system operates autonomously using onboard sensors that automatically detect accidents without human intervention. The system self-activates upon detecting abnormal acceleration patterns, automatically transmits data to the server, and triggers warning notifications to following vehicles, achieving high detection accuracy while minimizing operational complexity.
3Reliability
If accident information is not transmitted to following vehicles, then the communication system complexity is low, but the safety and response time deteriorate
Solution Approach 1:
The system implements feedback by continuously monitoring the positions of following vehicles relative to the accident scene and dynamically adjusting warning transmission. The server receives location data from following vehicles, determines their proximity to the accident, and activates or deactivates warnings accordingly, ensuring high road safety while maintaining communication system simplicity through condition-based activation.
Solution Approach 2:
The communication system changes parameters such as transmission power, message frequency, and warning activation thresholds based on the distance between following vehicles and the accident scene. By adjusting these parameters dynamically, the system ensures reliable safety warnings are transmitted only when necessary, improving road safety while avoiding the complexity of continuous high-power communication.

AI summary
A vehicle operation control server includes a communication device transmitting and receiving information to and from a vehicle through a network, an accident information collecting processor collecting detailed record data on an accident acquired by an event data recorder of an accident vehicle related to the accident through the communication device, and an accident information processing processor determining accident response measures for a subsequent vehicle that follows the accident vehicle based on the collected accident information.
