Lane Adaptive Lamp Control Preventing Glare via Dynamic Turning-Off Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intelligent lamp systems fail to accurately control lamp activation based on lane information, leading to glare and misrecognition issues due to median barriers, which can compromise driver visibility, especially when merging onto different lanes.
Innovation Solution
A lane adaptive lamp control apparatus and method that utilizes a lane sensor, determiner, and controller to identify the traveled lane through camera-based line type information and navigation system data, adjusting the lamp's turning-off zone accordingly to prevent glare and ensure visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If lamp control is based on light source detection through camera image processing, then glare prevention to opposing vehicles is achieved, but misrecognition occurs when median barriers are partially open causing frequent lamp on-off switching
Solution Approach 1:
The system performs preliminary lane identification and median barrier detection before controlling the lamp. By detecting the median barrier's position and state in advance through the camera, the system determines the appropriate lamp control strategy proactively, preventing misrecognition and frequent switching that would occur with reactive light-source-only detection.
Solution Approach 2:
The patent introduces lane information and median barrier detection as an intermediary between the camera and lamp control. Instead of directly controlling lamps based on detected light sources, the system uses lane context and barrier position as intermediate variables to make more accurate control decisions, reducing misrecognition errors.
2Object-affected harmful factors
If left side-upward lamps are consistently turned off based on navigation road information, then glare prevention is achieved when traveling on the first lane, but visibility is compromised when traveling on inner lanes (second or third lane)
Solution Approach 1:
The system dynamically adjusts lamp control based on the detected lane position. Instead of a static rule to always turn off left side-upward lamps, the controller adapts the lamp control strategy according to which lane the vehicle is currently traveling in, ensuring both glare prevention and adequate visibility for the specific driving context.
Solution Approach 2:
The patent applies different lamp control strategies to different lanes. Rather than a uniform approach, the system tailors the illumination pattern and lamp control to the local conditions of each lane, providing appropriate visibility for inner lanes while maintaining glare prevention for outer lanes with opposing traffic.
3Ease of operation
If lamp control is independent of lane information, then control simplicity is maintained, but fatal accidents may occur when merging into right side lane due to failure to ensure left side lane visibility
Solution Approach 1:
The system implements feedback by continuously monitoring lane position through camera-based detection and using this information to adjust lamp control in real-time. This closed-loop approach ensures that lane changes and merging maneuvers are detected, and lamp visibility is automatically adjusted to prevent accidents without requiring complex manual control.
