Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems fail to smoothly control vehicles near toll gates due to inconsistencies between actual and virtual lane widths, leading to potential deviations.
Innovation Solution
A vehicle control system that sets virtual lines based on gate positions, road signs, vehicle queues, and behaviors of surrounding vehicles, using a virtual line setter and gate passing controller to ensure smooth passage through toll gates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual lines are set using conventional methods, then lane keeping control can be performed on general roads, but vehicle control becomes unstable near toll gates where lane width changes
Solution Approach 1:
The virtual line setting method dynamically adapts to different road conditions by detecting toll gate areas and adjusting virtual line parameters accordingly. The system transitions from fixed conventional virtual lines to dynamically adjusted virtual lines that account for lane width variations near toll gates, improving control stability in previously problematic areas
Solution Approach 2:
The system changes key parameters of virtual lines including position, curvature, and width based on detected toll gate information. By modifying these parameters in response to toll gate detection, the system maintains accurate lane representation despite lane width changes, resolving the contradiction between stability and adaptability
2Ease of operation
If virtual lines are extended from pillar parts of the gate to the front side, then vehicle guidance is improved in gate areas, but complexity of virtual line setting increases
Solution Approach 1:
The system performs preliminary detection of toll gates and pre-calculates appropriate virtual line configurations before vehicles reach the gate area. By preparing virtual line settings in advance based on detected gate positions and characteristics, the system improves guidance quality without requiring complex real-time adjustments, thus managing complexity effectively
3Productivity
If virtual lines are set based on multiple factors including road signs, vehicle queues, and surrounding vehicle behaviors, then passage efficiency at toll gates is improved, but information processing complexity increases
Solution Approach 1:
The information processing system is designed to handle multiple types of data (road signs, vehicle queues, surrounding vehicle behaviors) through a unified processing framework. This multi-functional approach allows the system to integrate diverse information sources efficiently, improving passage efficiency while managing processing complexity through standardized handling procedures
Solution Approach 2:
The system introduces an intermediary processing layer that aggregates and synthesizes information from multiple sources before generating virtual line adjustments. This intermediary structure simplifies the overall processing complexity by providing a standardized interface between diverse information inputs and the virtual line setting mechanism, enabling efficient multi-factor analysis

AI summary
A vehicle control system includes a virtual line setter configured to set virtual lines in front of a gate on the basis of the position of the gate, and a gate passing controller configured to perform vehicle control when a vehicle passes through the gate on the basis of the virtual lines set by the virtual line setter.
