Camera-Based Rollover Risk Detection for External Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle safety systems are inadequate in detecting and mitigating rollover risks for both the vehicle and external vehicles, particularly in scenarios where the vehicle's center of gravity shifts during turns, leading to potential overturning.
Innovation Solution
An electronic apparatus equipped with a processor and camera that calculates a rollover index for external vehicles using artificial intelligence models, identifying vehicles based on height, road curvature, and characteristic parameters, and automatically adjusts the vehicle's driving strategy to avoid potential rollover risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If various sensors are provided in the vehicle to detect rollover risk, then the reliability of rollover detection is improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses camera images to create a visual copy representation of external vehicles, analyzing their characteristics (height, road curvature, position) to calculate rollover risk indices. This replaces the need for physical sensors on external vehicles while achieving reliable rollover detection through image-based data extraction and AI analysis.
2Ease of operation
If the vehicle's center of gravity shifts during turns, then the vehicle's maneuverability is improved, but the stability decreases leading to potential overturning
Solution Approach 1:
The system performs preliminary detection of external vehicles at risk of rollover by analyzing their characteristics (height ≥ preset height, road curvature ≥ preset curvature, position in blind spots) before actual rollover occurs. It calculates rollover risk indices in advance and provides warnings or autonomous control measures to prevent accidents, allowing the vehicle to maintain maneuverability while preemptively addressing stability risks.
3Reliability
If the vehicle provides warnings to the driver about potential rollover situations, then the safety is improved, but the response time may be delayed depending on driver reaction
Solution Approach 1:
The system implements autonomous control measures that enable the vehicle to take self-service actions without waiting for driver response. When external vehicles are detected at high risk of rollover (based on calculated indices from image analysis), the system can automatically adjust the host vehicle's driving strategy, such as avoiding maneuvers that could trigger rollover, thereby eliminating the delay associated with driver reaction time.

AI summary
Disclosed is an electronic apparatus for detecting risk factors around a vehicle. The present electronic apparatus comprises a communicator, a memory storing at least one computer-executable instruction, and a processor for executing the at least one computer-executable instruction, wherein the processor receives, through the communicator, an image obtained from a camera located to capture the outside of the vehicle, calculates a rollover index of an external vehicle on the basis of an image of the external vehicle included in the obtained image, and performs a preset operation according to the calculated rollover index.
