Lane Change Section Display for Natural Driver Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current travel controllers cannot effectively display lane change sections to drivers in a manner that is naturally recognizable, as the start and endpoint of a lane change may appear unnatural if adjusted based on changing vehicle motion, and the presence of other vehicles in the destination lane complicates the display of feasible lane change sections.
Innovation Solution
An apparatus and method that detect a lane change section with sufficient length and no other vehicles using a processor, presenting the entry position or endpoint closest to the vehicle on a display, with the lane change section represented in a manner that is easily recognizable by the driver, using a processor configured to analyze images from vehicle surroundings and determine feasible lane change sections based on a lane change threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the start point and endpoint of a lane change are adjusted based on changing vehicle motion plans, then the lane change control can adapt to dynamic conditions, but the displayed position may appear unnatural to the driver
Solution Approach 1:
The system determines and displays the lane change position in advance based on the initial lane change plan, before the actual lane change execution. This preliminary display provides a stable reference for the driver that does not change with dynamic adjustments during execution, while the control system separately adapts the actual lane change trajectory to changing conditions.
2Loss of information
If the lane change section display shows the complete detected section, then all feasible lane change positions are visible, but the display may become complex and difficult to recognize quickly
Solution Approach 1:
The system extracts and displays only the critical entry position information from the detected lane change section, rather than showing the entire section. This extraction principle focuses the display on the most important information needed by the driver (where to initiate lane change) while maintaining completeness of the underlying detection data for control purposes.
3Measurement precision
If the system detects lane change sections considering all surrounding vehicles, then the accuracy of feasible lane change identification is improved, but the processing complexity and time increase
Solution Approach 1:
The system applies different detection strictness levels to different spatial regions. In areas with high vehicle density, the system focuses detection resources on critical zones while using simplified detection in less critical areas. This local quality approach maintains high accuracy where needed while reducing overall processing complexity.

AI summary
An apparatus for displaying lane information detects a lane change section in an adjoining lane adjoining a travel lane of a vehicle from an image representing surroundings of the vehicle. The lane change section has a length in a travel direction greater than a lane change threshold indicating a length required for a lane change and includes no other vehicles. The apparatus presents an entry position on a display as a position indicating the lane change section when the entry position is inside the lane change section, and presents an endpoint of the lane change section closest to a current position of the vehicle on the display as a position indicating the lane change section when the entry position is outside the lane change section. The entry position is a position in a front-back direction at which the vehicle making a lane enters the adjoining lane.
