Adaptive Lane Centering Offset Control for Driver Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous vehicle lane centering systems lack the ability to adapt to individual driver preferences and biases, as they do not effectively detect or compensate for subconscious or habitual steering offsets, which can lead to inconsistent lane keeping.
Innovation Solution
A system and method that activate a lane centering control system, detect driver steering overrides, monitor lane centering offsets, and adjust the lane centering offset to compensate for driver biases by using a combination of sensors and algorithms to determine and set a new offset based on consistent driver tendencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a lane centering control system is activated to maintain vehicle position, then lane keeping stability is improved, but the system cannot adapt to individual driver preferences and biases
Solution Approach 1:
The lane centering system dynamically adjusts the offset parameter based on detected driver steering behavior. The system transitions from a static fixed offset to a dynamic adaptive offset that evolves with driver interactions, allowing the control parameters to change in response to driver preferences while maintaining stability through controlled adaptation.
Solution Approach 2:
The system implements feedback by monitoring driver steering overrides and using this information to adjust the lane centering offset. The feedback loop detects when drivers manually correct the lane centering position and automatically adapts the offset to accommodate these corrections, enabling the system to learn and adapt to individual driver preferences while maintaining overall lane keeping stability.
2Device complexity
If the lane centering system maintains a fixed offset, then system simplicity is preserved, but driver bias compensation is lost
Solution Approach 1:
The lane centering system performs self-adjustment by automatically detecting driver steering patterns and modifying its own offset parameter without requiring manual driver input or complex configuration interfaces. The system serves itself by learning from driver behavior and autonomously adapting to compensate for driver biases, maintaining simplicity while improving reliability through self-learning capabilities.
3Reliability
If the system monitors and adjusts lane offset continuously, then driver bias compensation is improved, but computational load and system complexity increase
Solution Approach 1:
The system applies partial monitoring and adjustment by focusing computational resources on detecting significant driver override events rather than continuously analyzing all steering inputs. Instead of excessive continuous adjustment, the system makes targeted offset modifications only when driver bias is detected, reducing computational load while maintaining effective driver bias compensation through selective action.

AI summary
A system and method for providing adaptive lane centering in an autonomous or semi-autonomous vehicle driving system includes activating a lane centering control system, detecting a driver steering override of the lane centering control system, monitoring a lane centering offset when a driver override condition is detected, determining if the lane centering offset represents a driver bias and adjusting the lane centering offset in the lane centering control system to compensate for the driver bias.
