Adaptive Steering Assistance Control for Driver Tendency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering assistance devices continue to assist vehicles in staying centered in a lane, making it difficult for drivers who tend to steer to the left or right, as they do not adapt to the driver's steering tendency.
Innovation Solution
A steering assistance device with a control unit that adjusts steering assistance based on measured lateral deviation and lane curvature, allowing the vehicle to deviate by a predetermined amount when the deviation is within a range for a set time, and adjusts torque generation over time to align with the driver's steering tendency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the steering assistance device continues to assist steering to make the vehicle travel in the center of the lane, then the vehicle positioning accuracy is improved, but the driver's steering operation becomes difficult due to conflict with the driver's steering tendency
Solution Approach 1:
The steering assistance control is dynamically adjusted based on the detected steering tendency. The control unit changes the assistance characteristics according to the driver's steering pattern detected over time, making the assistance adaptive rather than fixed. This resolves the contradiction by making the system flexible enough to accommodate driver preferences while maintaining positioning accuracy.
Solution Approach 2:
The system detects the driver's steering tendency by monitoring steering operations over time and uses this feedback to adjust the steering assistance characteristics. The control unit continuously adapts the assistance based on the detected tendency, creating a closed-loop system that balances positioning accuracy with driver comfort and ease of operation.
2Ease of operation
If the steering assistance adapts to the driver's steering tendency by allowing deviation from lane center, then the ease of operation is improved, but the vehicle positioning accuracy deteriorates
Solution Approach 1:
The system applies different control strategies for different situations. When a steering tendency is detected, the assistance is adjusted locally to accommodate that tendency within a predetermined range, while maintaining overall lane positioning accuracy. This localized adaptation resolves the contradiction by allowing deviation only when and where it aligns with driver preference without compromising overall positioning.
Solution Approach 2:
The control unit changes the steering assistance parameters based on the detected steering tendency. By adjusting assistance characteristics according to the driver's steering pattern, the system maintains positioning accuracy while adapting to driver preferences, thus resolving the contradiction between positioning precision and ease of operation.
3Adaptability or versatility
If the steering assistance controls the amount of assistance based on lateral deviation for extended periods, then the adaptability to driver tendency is improved, but the system complexity increases
Solution Approach 1:
The control unit detects steering tendency in advance by monitoring steering operations over a predetermined period before applying the adapted assistance characteristics. This preliminary detection phase allows the system to adapt smoothly without complex real-time adjustments, resolving the contradiction between adaptability and system complexity.
Solution Approach 2:
The control unit performs multiple functions using the same basic detection and control mechanisms: it detects steering tendency, determines assistance characteristics, and applies adjusted assistance. This multi-functionality approach achieves adaptability without proportionally increasing system complexity, as the same hardware and software infrastructure serves multiple purposes.

AI summary
A steering assistance device 1 includes: a steering assistance unit 11, which assists the steering of a vehicle V to make the vehicle V travel in the center of a lane; a deviation amount measurement unit 101, which measures the amount of lateral deviation of the vehicle V from the center of a lane; and a steering control unit 103, which controls the amount of steering assistance by the steering assistance unit 11 such that the vehicle V travels with deviation from the center of the lane by the predetermined amount, in a case where the measured amount of lateral deviation is within a predetermined range from a predetermined amount for a predetermined period of time.
