Lane-keeping Control System with Adaptive Basis Following Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lane-keeping control systems fail to account for individual drivers' inclinations, leading to potential malfunctions and accidents, especially on curved roads, as they do not adapt steering control to reflect the driver's intended position within the lane.
Innovation Solution
A system that includes a sensor for lane detection, a lane-keeping controller, and a basis following position setting unit, which recognizes road curvature and detects driver override to set a specific lateral offset as the basis following position, reflecting the driver's preferred position, thereby generating adaptive auxiliary steering torque for lane-keeping control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lane-keeping control system simply makes the vehicle follow the center of the lane or prevents lane escape, then the lane-keeping control function is provided, but the different driving inclination of each driver is not reflected
Solution Approach 1:
The system dynamically adjusts the basis following position based on detected driver overrides. When a driver override is detected, the system monitors the lateral offset changing rate and determines the driver's preferred position, then sets this as the new basis following position. This dynamic adaptation allows the system to reflect individual driver inclinations without requiring a completely new control architecture.
Solution Approach 2:
The system implements feedback by monitoring the lateral offset changing rate when a driver override is detected. The basis following position setting unit continuously observes driver steering actions and uses this feedback to determine when the driver has established a preferred position, then adjusts the control target accordingly. This feedback mechanism enables the system to adapt to driver preferences while maintaining stable control.
2Reliability
If the conventional lane-keeping control system performs control without reflecting driver inclination, then the control is simple, but malfunctions and accidents may occur due to conflicts with driver steering intention
Solution Approach 1:
The system performs preliminary detection of driver overrides before making control adjustments. When a driver override is detected, the system proactively monitors the lateral offset changing rate and prepares to adjust the basis following position, preventing potential conflicts between automated control and driver intention. This preliminary action approach enhances reliability by anticipating driver needs before conflicts arise.
Solution Approach 2:
The system uses feedback from monitoring the lateral offset changing rate to determine when driver override has stabilized, then adjusts the basis following position accordingly. This feedback mechanism ensures that control adjustments are made only when appropriate, preventing malfunctions while adapting to driver preferences.
3Adaptability or versatility
If the system sets a fixed basis following position, then the control is straightforward, but it cannot adapt to different driver preferences on curved roads
Solution Approach 1:
The system detects driver override by monitoring the lateral offset changing rate and uses this feedback to determine when the driver has established a preferred position. The continuous monitoring of lateral offset changes provides the necessary information to detect driver intentions without requiring additional complex sensors or measurement systems.
Solution Approach 2:
The system uses the existing lane-keeping control data and lateral offset information to detect driver overrides and determine driver preferences. By utilizing data already available in the control system, the patent avoids the need for additional complex detection mechanisms while still achieving adaptability to driver preferences.

AI summary
A disclosure relates to a basis following position setting method and a lane-keeping control system, and more particularly, the disclosure relates to a method for setting a basis following position, which sets a basis following position that a vehicle follows in reflection of a driving inclination of a driver, and a system for lane-keeping control, which causes a vehicle to follow the basis following position set by the method for setting the basis following position and thus performs a lane-keeping control function in reflection of a driving inclination of a driver.
