Adaptive Lane Keeping System for Adjacent Vehicle Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated lane keeping systems do not account for vehicles or objects in adjacent lanes, leading to potential collisions during lane changes, especially in narrow lanes, and disable lane keeping functions when the turn signal is activated, failing to provide warnings for obstacles in the new driving position.
Innovation Solution
An adaptive lane keeping system that detects objects in adjacent lanes and adjusts the vehicle's position within its own lane to maintain a safe distance, while preventing lane keeping function disengagement during potential collisions by providing warnings and potentially executing corrective steering maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lane keeping system centers the vehicle in its lane, then the vehicle maintains optimal positioning in the lane, but the vehicle may collide with adjacent vehicles in narrow lanes
Solution Approach 1:
The system adjusts the vehicle's lateral position based on local conditions in adjacent lanes. When vehicles are detected in adjacent lanes, the system shifts the vehicle away from the center position toward a safer lateral position, creating different positioning strategies for different spatial zones around the vehicle
Solution Approach 2:
The lane keeping system dynamically adjusts the desired lateral position based on real-time detection of adjacent vehicles. The target position transitions from center-lane positioning to offset positioning when adjacent vehicles are detected, and the system continuously adapts as vehicles enter or leave adjacent lanes
2Adaptability or versatility
If the lane keeping function disengages when turn signal is activated, then the driver can freely change lanes, but the system fails to warn drivers of obstacles in the new driving position
Solution Approach 1:
The system provides feedback to the driver about obstacles detected in the intended lane change path. When the turn signal is activated, the system monitors for adjacent vehicles and provides warnings through the HMI, giving the driver information about potential collision risks before the lane change is executed
Solution Approach 2:
The system performs preliminary detection and warning before the lane change occurs. By detecting adjacent vehicles and providing warnings in advance through the HMI, the system allows the driver to make an informed decision about whether to proceed with the lane change

AI summary
A method and apparatus for piloting a vehicle is herein disclosed. The method entails first using a lane keeping system to detect objects in lanes adjacent to the lane currently occupied by the vehicle and then adjusting the position of the vehicle within the occupied lane-relative to a detected object.
