Driver Assistance Device Avoidance Steering Control Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to adjust avoidance steering control to match the comfort level of individual drivers, leading to driver anxiety when the avoidance distance is not sufficient.
Innovation Solution
A driver assistance device that performs avoidance steering control and adjusts the avoidance amount based on the frequency of cancellation by the driver, allowing for customizable threshold values and avoidance distances to align with the driver's sense of safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If avoidance steering control is performed with a fixed avoidance amount, then the control system is simple and reliable, but the driver may feel anxious when the avoidance distance does not match their expected safety distance
Solution Approach 1:
The avoidance amount is made dynamic rather than fixed. The system automatically adjusts the avoidance amount based on the driver's operational history and cancellation frequency, allowing the control characteristics to adapt to individual driver preferences while maintaining system reliability
Solution Approach 2:
The system serves itself by automatically learning from driver behavior patterns. Through monitoring cancellation frequency and steering operations, the system self-adjusts the avoidance amount without requiring manual calibration or complex driver input, reducing overall system complexity while improving driver comfort
2Ease of operation
If the avoidance amount is increased to ensure driver comfort, then driver anxiety is reduced, but the vehicle may not respond efficiently to urgent avoidance situations
Solution Approach 1:
The avoidance amount dynamically adapts to each driver's comfort threshold through continuous monitoring of cancellation frequency. This allows the system to optimize between comfort and efficiency for each individual driver, rather than using a one-size-fits-all approach that compromises either comfort or response efficiency
Solution Approach 2:
The system changes the avoidance amount parameter based on observed driver behavior patterns. By analyzing cancellation frequency and adjusting the avoidance amount accordingly, the system finds the optimal balance between driver comfort and urgent situation response efficiency for each driver
3Ease of operation
If the avoidance steering control is frequently cancelled by the driver, then the driver maintains control, but the system cannot learn the driver's preferences efficiently
Solution Approach 1:
The system implements feedback mechanisms that monitor cancellation frequency and use this information to adjust the avoidance amount. This feedback loop allows the system to learn driver preferences over time while maintaining driver control, converting cancellation events into learning opportunities rather than pure losses

AI summary
The driver assistance device according to the present disclosure performs avoidance steering control for controlling the steering mechanism of the host vehicle so that the host vehicle avoids the target when the target object exists in front of the host vehicle. When the occupant inputs a steering torque equal to or higher than a threshold value to the steering mechanism during execution of the avoidance steering control, the driver assistance device cancels the avoidance steering control. Then, in accordance with the frequency of cancellation of the avoidance steering control, the driver assistance device changes the avoidance amount by the avoidance steering control.
