Vehicle Hazard Detection Range Adjustment During Turning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance technologies struggle to effectively detect and alert drivers to hazardous points on the road, especially when vehicles are turning, due to limitations in the range of detection and adaptability to changing driving conditions.
Innovation Solution
The assistance apparatus dynamically adjusts the range of detection based on the vehicle's speed and turning status, extending the detection range in the turning direction to ensure timely detection of hazardous points, even when the vehicle is turning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection range is extended in the turning direction, then the ability to detect hazardous points is improved, but the device complexity increases
Solution Approach 1:
The detection range is dynamically adjusted based on the vehicle's turning status. When the vehicle is turning, the detection range is extended in the turning direction; when straight, the range returns to normal. This dynamic adjustment improves hazardous point detection during turns without permanently increasing system complexity
Solution Approach 2:
The patent changes the detection range parameters according to vehicle operating conditions. By modifying the detection range parameters based on turning status, the system achieves better detection capability during turns while maintaining manageable complexity through parameter adjustment rather than structural changes
2Adaptability or versatility
If the detection range is extended dynamically based on turning status, then the adaptability to changing driving conditions is improved, but the calculation load increases
Solution Approach 1:
The system adapts to different driving conditions by changing detection range parameters based on turning status. This approach provides adaptability to varying driving conditions while keeping the calculation load manageable through parameter adjustment rather than complex real-time computations

AI summary
An assistance apparatus includes: a receiving unit which receives information indicating a travelling hazardous point which is transmitted from an outside of a vehicle; a calculating unit which calculates a distance and an azimuth from the vehicle to the travelling hazardous point based on the travelling hazardous point and a current location of the vehicle; a detecting unit which detects the travelling hazardous point within a range of detection set ahead of the vehicle in a running direction; an assistance controlling unit which provides travelling assistance when the travelling hazardous point is detected within the range of detection; a turning detecting unit which detects that the vehicle is turning; and a range changing unit which extends the range of detection in a turning direction of the vehicle when it is detected by the turning detecting unit that the vehicle is turning.
