Vehicle Accident Warning via Navigation Server for Secondary Crash Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
After a traffic accident occurs, vehicles passing through the accident site are prone to secondary accidents and traffic congestion due to the inability of the involved vehicle to leave the scene quickly, leading to prolonged road obstruction.
Innovation Solution
An accident warning method that generates and sends warning information to vehicles approaching the accident location via a navigation server, utilizing satellite positioning, vehicle sensors, and onboard cameras to determine accident details and severity, enabling timely warnings to prevent secondary accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the involved vehicle remains at the accident site for rescue operations, then rescue assistance can be provided to occupants, but the road remains obstructed causing secondary accidents and traffic congestion
Solution Approach 1:
The system performs preliminary action by detecting the accident through sensor data (acceleration, collision forces) and automatically sending warning information to the navigation server before the vehicle is fully stopped or before rescue operations begin. This advance warning allows approaching vehicles to be alerted in time, preventing secondary accidents while the accident vehicle remains stationary for rescue.
Solution Approach 2:
The navigation server acts as an intermediary that receives accident warning information from the involved vehicle and relays it to approaching vehicles. This mediator system enables communication between the accident scene and approaching traffic without requiring the accident vehicle to move or manually warn other drivers, thus maintaining road safety during rescue operations.
2Productivity
If the accident vehicle is quickly removed from the scene, then road obstruction is reduced, but rescue operations may be compromised
Solution Approach 1:
The warning system is activated immediately upon accident detection, performing the safety function in advance before the vehicle is removed. This allows the vehicle to be quickly towed away after the warning is sent, improving road clearance speed while ensuring approaching vehicles have already been alerted.
3Reliability
If comprehensive accident information is collected and transmitted, then warning accuracy and rescue effectiveness are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system uses multi-functional sensors that can detect various accident parameters (acceleration, collision forces, vehicle attitude) simultaneously. These sensors serve multiple purposes: detecting the accident occurrence, determining accident severity, and providing information for rescue operations, thereby improving warning accuracy without proportionally increasing system complexity.
Solution Approach 2:
The system automatically processes and transmits accident information without requiring manual intervention. The control unit automatically detects accident parameters, generates warning messages, and sends them to the navigation server, reducing the complexity of manual data collection and transmission while maintaining high warning accuracy.

AI summary
The present disclosure provides an accident warning method, apparatus, storage medium, controller, and vehicle. According to the accident warning method proposed by the present disclosure, in response to detecting that the host vehicle has been involved in a traffic accident, accident warning information corresponding to the traffic accident is generated, wherein the accident warning information comprises the accident location associated with the traffic accident. The accident warning information is sent to a navigation server, such that the navigation server sends the accident warning information to vehicles to be warned that are about to pass through the accident location. In this way, vehicles approaching the accident location can be warned in advance when a traffic accident occurs, thereby improving driving safety.
