Lane Change Priority Control for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane change systems fail to effectively prevent collisions when multiple vehicles attempt to change lanes simultaneously, as they do not adequately consider the priority of lane changes based on accessibility to the target road and join points.
Innovation Solution
An apparatus and method that includes a collision judger to identify potential collision risks and a priority determiner to determine which vehicle should change lanes first, considering accessibility to the target road and join points, using sensors and communication systems to assess the situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lane change control is performed without considering vehicle priority, then the lane change process is simple and fast, but collision risk increases when multiple vehicles attempt to change lanes simultaneously
Solution Approach 1:
The system performs preliminary determination of priority vehicles before executing lane changes. The collision judger identifies potential collision risks in advance, and the priority determiner establishes which vehicle should proceed first based on pre-calculated priority metrics, preventing collisions before they occur rather than reacting to them
Solution Approach 2:
The patent introduces an intermediary control system that mediates between multiple vehicles attempting lane changes. The collision judger and priority determiner act as intermediaries that coordinate lane change decisions, ensuring that only the highest priority vehicle proceeds while others wait, thus preventing collisions without requiring complex direct vehicle-to-vehicle negotiation
2Reliability
If priority determination based on accessibility to target road and join point is implemented, then lane change safety is improved, but the processing time and computational load increase
Solution Approach 1:
The system calculates priority metrics including accessibility to target road and join point in advance, before the actual lane change execution. This preliminary calculation allows the priority determiner to quickly make decisions when lane change opportunities arise, reducing real-time processing delays
Solution Approach 2:
The patent dynamically adjusts priority determination parameters such as accessibility metrics and join point proximity based on real-time vehicle positions and road geometry. By changing these parameters adaptively, the system optimizes safety decisions while minimizing unnecessary computational overhead for standard scenarios

AI summary
There are provided an apparatus and a method for controlling a lane change considering priority. The apparatus for controlling a lane change includes: a collision judger checking whether or not there is an object vehicle having collision possibility that attempts to change a lane from a region of interest road corresponding to an ego-road on which an ego-vehicle is being driven to a target road to which the ego-vehicle changes the lane, before or during the lane change of the ego-vehicle; and a priority determiner determining a priority vehicle that first performs the lane change among the ego-vehicle and the object vehicle considering at least one of accessibility to the target road of the ego-vehicle and the object vehicle when there is the object vehicle, and accessibility to a join point when the object vehicle or the ego-vehicle is positioned on a road to be joined.
