Driver Involvement Feedback Display for Autonomous Driving Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers may feel uncomfortable when there is a discrepancy between the vehicle's evaluation of their condition and their own self-evaluation, leading to discomfort from alerts or termination of autonomous driving or driving assist due to perceived decreases in driving involvement degree.
Innovation Solution
A driver evaluation information providing device that monitors the driver's condition using a camera and sensors, evaluates their driving involvement degree, and provides real-time feedback through visual and auditory means, including a bar-shaped display that changes length and highlights to indicate changes in involvement, helping the driver maintain focus and awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device outputs alerts or terminates autonomous driving based on evaluated driving involvement degree, then safety and monitoring effectiveness are improved, but driver comfort and acceptance deteriorate due to perceived discrepancy between device evaluation and driver self-evaluation
Solution Approach 1:
The device provides continuous feedback to the driver about the evaluated driving involvement degree through display units. This feedback loop allows the driver to understand the device's perception of their state, reducing the discrepancy between driver self-evaluation and device evaluation, thereby maintaining comfort while preserving monitoring effectiveness
Solution Approach 2:
The display unit acts as an intermediary that translates the device's internal evaluation into visible information for the driver. This intermediary communication channel bridges the gap between device monitoring and driver awareness, reducing discomfort caused by perceived evaluation discrepancies
2Measurement precision
If the device continuously monitors and evaluates driver condition, then detection accuracy is improved, but information loss between device evaluation and driver perception increases
Solution Approach 1:
By providing continuous feedback about the evaluated driving involvement degree to the driver, the system reduces information loss. The driver gains awareness of the device's evaluation criteria and current status, aligning their perception with the actual measurement being taken

AI summary
A driver evaluation information providing device includes a driver monitoring unit configured to monitor a condition of a driver of a vehicle based on an image of the driver captured by a driver monitor camera of the vehicle, a driving involvement degree evaluation unit configured to evaluate a driving involvement degree of the driver based on a result of monitoring of the condition of the driver by the driver monitoring unit, and an information providing unit configured to provide, to the driver, information about the driving involvement degree evaluated by the driving involvement degree evaluation unit.
