Virtual Moving Body Simulation for Overturning Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving bodies lack precision in predicting the possibility of overturning, especially when encountering obstacles or slopes, as they rely on relative distance and road surface shape without considering the vehicle's inclination and occupant's center of gravity, leading to inaccurate warnings and speed limitations.
Innovation Solution
A moving body equipped with detection units for three-dimensional space and state information, which creates a virtual environment to simulate the actual environment, allowing a virtual moving body to travel on a virtual road surface, predicting overturning possibilities based on posture changes and controlling the actual moving body to avoid such scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a moving body uses simple distance and road surface shape detection to predict overturning, then the device complexity is reduced, but the measurement precision of overturning possibility is insufficient
Solution Approach 1:
The patent creates a virtual moving body that copies the physical characteristics and state of the actual moving body, and a virtual environment that replicates the real road surface and spatial conditions. This virtual copy allows for complex simulation and prediction of overturning scenarios without requiring additional physical sensors or hardware, thereby improving measurement precision while avoiding excessive device complexity
Solution Approach 2:
The patent introduces a virtual environment as an intermediary between the simple detection units and the complex prediction requirements. The virtual environment acts as a mediator that transforms basic detection data (distance, road surface shape) into comprehensive overturning risk assessment by simulating various travel scenarios, thus bridging the gap between simple detection and precise prediction
2Reliability
If the moving body performs accurate overturning prediction with virtual simulation, then the reliability of safety control is improved, but the loss of time for computation and simulation increases
Solution Approach 1:
The patent performs virtual simulation and overturning prediction in advance before the actual travel occurs. By allowing the virtual moving body to travel on the virtual road surface beforehand and predict overturning possibilities, the system prepares safety control strategies ahead of time, ensuring reliable safety control while minimizing real-time computation delays during actual travel
Solution Approach 2:
The patent dynamically adjusts the simulation parameters and virtual travel conditions to match the actual real-time state of the moving body. By updating the virtual environment and simulation based on current detection data, the system maintains high reliability of safety control while optimizing computation time through adaptive, rather than static, simulation approaches
3Measurement precision
If the moving body uses comprehensive state detection and virtual simulation, then the prediction accuracy of overturning is improved, but the ease of operation is reduced due to complex control decisions
Solution Approach 1:
The patent implements a feedback mechanism where the virtual simulation results directly inform and guide the control decisions for the actual moving body. The control unit uses the predicted overturning possibilities from the virtual environment to automatically adjust travel parameters, providing accurate safety control through automated feedback loops rather than complex manual control decisions, thus maintaining ease of operation while achieving high prediction accuracy

AI summary
A moving body includes: a first detection unit configured to detect three-dimensional information on a space in which the moving body travels; a second detection unit configured to detect a state of the moving body; and a control unit configured to predict a possibility of overturning of a virtual moving body by allowing the virtual moving body corresponding to the moving body to travel on a virtual road surface in a virtual space prior to a travel of the moving body on a road surface based on a shape of the virtual road surface in the virtual space corresponding to the detected three-dimensional information and based on the detected state of the moving body, and performs control depending on the predicted possibility of overturning.
