Driving Support Apparatus Dynamic Warning Criteria Road Curvature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support systems fail to adapt their warning and assisting criteria effectively based on the degree of curve and width of a road, leading to inadequate collision risk management for drivers, as they rely on fixed determination criteria regardless of road curvature and width.
Innovation Solution
A driving support apparatus and method that dynamically change the warning and assisting criteria based on the degree of curve and width of the road, using curvature radius and road width to determine whether to issue warnings or perform assisting actions based on distance or arrival allowance time in the widthwise or traveling direction, ensuring the vehicle stays within the road boundaries and mitigates collision risks felt by the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed determination criteria are used for warning and assisting regardless of road curvature, then the system is simple to operate, but the adaptability to different road conditions deteriorates
Solution Approach 1:
The determination criteria dynamically change based on the degree of curve of the running road. The system automatically adjusts the warning and assisting thresholds according to real-time road curvature data, transitioning from static fixed criteria to dynamic adaptive criteria that respond to changing road conditions.
Solution Approach 2:
The system changes the determination criteria parameters based on the degree of curve of the road. When the road curvature increases, the system adjusts the warning distance and assisting thresholds to match the driver's perceived collision risk, thereby adapting to different road geometries without requiring manual intervention.
2Adaptability or versatility
If the determination criterion is changed based on degree of curve, then the adaptability to road conditions improves, but the device complexity increases
Solution Approach 1:
The system incorporates feedback from road curvature detection to automatically adjust determination criteria. The degree of curve of the running road is continuously monitored, and this information feeds back into the warning and assisting control logic, enabling automatic adaptation without adding complex manual adjustment mechanisms.
Solution Approach 2:
The system performs self-adjustment of determination criteria based on detected road conditions. By using the degree of curve information to automatically modify warning and assisting thresholds, the system serves itself rather than requiring external intervention, thereby reducing operational complexity despite increased adaptability.
3Device complexity
If warning and assisting criteria do not adapt to road curvature, then the device complexity remains low, but the collision risk management effectiveness deteriorates
Solution Approach 1:
The determination criteria dynamically change based on the degree of curve of the running road. The system automatically adjusts the warning and assisting thresholds according to real-time road curvature data, transitioning from static fixed criteria to dynamic adaptive criteria that respond to changing road conditions.
Solution Approach 2:
The system changes the determination criteria parameters based on the degree of curve of the road. When the road curvature increases, the system adjusts the warning distance and assisting thresholds to match the driver's perceived collision risk, thereby adapting to different road geometries without requiring manual intervention.

AI summary
A driving support apparatus that sets a running road, on which a vehicle is able to run, on the basis of a road marking that indicates a lane boundary or a prohibited area and that, when the vehicle deviates from the running road, issues a warning or performs assisting so as to cause the vehicle to run within the running road changes a determination criterion, based on which a warning is issued or assisting is performed so as to cause the vehicle to run within the running road, on the basis of a degree of curve of the running road.
