Lane-Related ADAS Control at Lane-Free Divergence Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lane-related Advanced Driver Assistance Systems (ADAS) malfunction when vehicles approach lane-free divergence points, leading to unnecessary lane maintenance controls and warnings, and increased risk of accidents due to misinterpretation of driver intentions.
Innovation Solution
A system that uses a camera and processor to identify driver intentions by analyzing changes in lane width and distance to edge lanes, activating or deactivating ADAS functions and controlling turn signal lamps accordingly to align with the driver's intended lane change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lane-related ADAS performs lane maintenance control based on recognized current driving lane, then the system provides lane keeping support, but unnecessary lane maintenance control is generated at lane-free divergence points
Solution Approach 1:
The system performs preliminary detection of divergence point sections ahead of the vehicle using map data or road sign recognition. When a divergence point is detected, the system proactively deactivates the lane-related ADAS function before the vehicle reaches the problematic area, preventing unnecessary lane maintenance control from being generated while the driver intends to change lanes.
2Reliability
If lane-related ADAS generates lane departure warning when vehicle leaves driving lane, then the system provides safety warning, but false warnings are generated when driver intends to change lanes at divergence points
Solution Approach 1:
The system detects divergence point sections in advance using map data or road sign recognition and deactivates the lane-related ADAS function before the vehicle enters the divergence area. This preliminary deactivation prevents the system from generating false lane departure warnings when the driver legitimately intends to change lanes at the divergence point.
3Reliability
If vehicle follows host vehicle without knowing lane change intention, then following vehicle maintains safe distance, but accident risk increases due to unpredictable lane change
Solution Approach 1:
The system activates turn signal lamps when the vehicle approaches a detected divergence point section, providing visual feedback to following vehicles about the intended lane change. This feedback mechanism allows following vehicles to anticipate the lane change maneuver, maintain appropriate following distance, and adjust their positioning accordingly, thereby reducing accident risk.
4Productivity
If ADAS function is continuously activated, then lane support is always available, but system malfunctions at specific road sections without indication lines
Solution Approach 1:
The system uses map data or road sign recognition to detect divergence point sections in advance and deactivates the lane-related ADAS function before the vehicle reaches these problematic areas. This selective deactivation maintains high lane support availability during normal driving while preventing system malfunctions at specific road sections without proper indication lines.

AI summary
The present disclosure relates to a lane-related advanced driver assistance system and a control method, and a vehicle having the same. A system according to an embodiment of the present disclosure may include a memory for storing an image captured by a camera of a vehicle; and a processor for controlling a lane-related Advanced Driver Assistance System (ADAS) in the vehicle using information stored in the memory, wherein the processor is configured to: identify a driver's intention in a rear region of a target section, which is a divergence point section without an indication line, using the image; and determine whether to perform the lane-related ADAS function in the target section according to the identified driver's intention.
