Driving Assistance End Position Adjustment for Blind Spot Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving assistance devices may end assistance prematurely without providing necessary information to drivers, particularly when merging from a non-priority road to a priority road, especially if there are parked vehicles on the priority road, leading to potential safety hazards due to blind spots.
Innovation Solution
A driving assistance device that adjusts the end position of assistance based on traffic conditions, including the presence of stopped or slowing vehicles on the priority road, ensuring the driver can visually confirm the merging path before assistance ends, thereby continuing assistance until the driver is in a safe position to merge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If driving assistance ends at the boundary of non-priority road and priority road, then the assistance system operates efficiently with clear termination point, but necessary information may not be provided to driver when parked vehicles create blind spots
Solution Approach 1:
The assistance end position is made dynamic rather than fixed. The system automatically adjusts the termination point of driving assistance based on real-time detection of parked vehicles and blind spot conditions. When blind spots are detected, the assistance end position is extended beyond the normal road boundary to ensure drivers receive necessary information about priority road traffic conditions.
Solution Approach 2:
The system implements feedback by continuously monitoring traffic conditions on the priority road, detecting parked vehicles that create blind spots, and using this information to adjust the assistance end position. This closed-loop control ensures assistance is extended only when necessary, providing reliable safety information while avoiding unnecessary prolonged assistance.
2Reliability
If driving assistance is extended to account for blind spots created by parked vehicles, then driver safety is improved, but assistance may continue longer than necessary increasing system operation time
Solution Approach 1:
The assistance system dynamically adjusts its operation duration based on detected conditions. Rather than using a fixed termination point, the system extends assistance only when parked vehicles creating blind spots are detected, and returns to normal termination when conditions are clear, optimizing both safety and operational efficiency.
Solution Approach 2:
The system changes the parameter of assistance end position based on traffic conditions. When blind spots are detected, the end position parameter is adjusted to extend beyond the normal boundary; when no blind spots exist, the parameter reverts to the standard termination point, allowing flexible adaptation to varying safety requirements.
3Loss of information
If driving assistance provides comprehensive information about priority road conditions, then driver decision-making is improved, but system complexity increases
Solution Approach 1:
The system applies local quality by providing enhanced information only in specific locations where blind spots exist due to parked vehicles. Rather than continuously providing comprehensive traffic information along the entire approach road, the system targets assistance extension and information provision to specific problem areas, reducing overall system complexity while maintaining necessary information flow.

AI summary
A driving assistance device which performs driving assistance for an assisted vehicle A traveling on a non-priority road 40 and trying to merge into a priority road 50 on the basis of the presence of a vehicle B traveling on the priority road 50 includes an assistance processing section 16 which changes the end position of driving assistance on the basis of traffic conditions on a first lane 51, which is nearest to the non-priority road 40, of lanes of the priority road 50. Accordingly, it is possible to perform appropriate driving assistance for a driver.
