Lane-Change Candidate Area Display Using Dynamic Safety Distances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems struggle to accurately identify a target area for lane changes due to difficulties in distinguishing between candidate areas, especially when considering the behaviors and positions of adjacent vehicles.
Innovation Solution
A vehicle control apparatus that utilizes sensors to determine front and rear safety distances based on vehicle characteristics and driving information, identifies candidate areas for lane changes by excluding unsafe zones, and provides visual guidance through a graphic user interface (GUI) for safe lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vehicle control apparatus displays only whether it is possible to make a lane change in real time, then the system complexity is reduced, but the user cannot identify a target area intended by the user among a plurality of candidate areas
Solution Approach 1:
The patent segments the adjacent lane into multiple candidate areas (first candidate area, second candidate area, etc.) based on the positions of other vehicles. Each candidate area is evaluated independently for lane change feasibility, allowing the system to provide detailed spatial information without overwhelming complexity.
Solution Approach 2:
The patent adds a spatial dimension to the display by showing not just whether a lane change is possible, but specifically where in the adjacent lane the change can occur. This transforms a binary yes/no indication into a multi-point spatial distribution of candidate areas.
2Measurement precision
If the vehicle control apparatus calculates safety distances for multiple other vehicles considering their speeds and accelerations, then the accuracy of target area identification is improved, but the computational complexity increases
Solution Approach 1:
The patent applies different safety distance calculation methods locally to different vehicles based on their specific characteristics. For vehicles traveling in the same direction, one calculation method is used, while for vehicles traveling in opposite directions, a different method is applied, optimizing both accuracy and computational efficiency.
Solution Approach 2:
The patent dynamically adjusts safety distance parameters based on real-time vehicle characteristics such as speed, acceleration, and direction. The system modifies the safety distance values according to the relative motion states of other vehicles, improving identification accuracy through adaptive parameter adjustment.
