Driver Gaze-Aware Driving Support Control for Risk Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle driving support systems fail to provide appropriate control based on the driver's sight line and peripheral environment during travel, often resulting in excessive notifications and inefficient driving support.
Innovation Solution
A vehicle control apparatus comprising an information acquisition unit, a risk prediction unit, a sight line specifying unit, and a control unit that predicts potential risks, estimates the driver's sight line, and adjusts driving support based on the deviation between the predicted risk region and the driver's sight line, using a combination of cameras, LiDAR, and machine learning models to provide direct or indirect guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving support control is provided continuously during traveling, then driving safety is improved, but excessive notifications are generated causing driver distraction
Solution Approach 1:
The system dynamically changes the notification parameter (whether to provide driving support control) based on the deviation between the risk region and driver's sight line. When deviation is large, notifications are provided; when deviation is small, notifications are suppressed, thus adapting the notification behavior to the current driving context.
Solution Approach 2:
The system uses feedback from the sight line detection and risk region prediction to adjust the notification behavior. The control unit continuously monitors the deviation between risk region and sight line position, and adjusts whether to provide driving support control based on this feedback, creating a closed-loop system that prevents excessive notifications.
2Object-generated harmful factors
If driving support control is reduced to avoid excessive notifications, then driver distraction is reduced, but driving safety may be compromised
Solution Approach 1:
The system dynamically adjusts the support level parameter based on the deviation magnitude. When deviation is large (driver not looking at risk), full driving support control is provided. When deviation is small (driver already monitoring risk), support is reduced or stopped, optimizing both safety and driver experience.
3Adaptability or versatility
If the system monitors both risk region and sight line position continuously, then appropriate driving support is provided, but system complexity increases
Solution Approach 1:
The notification control unit performs multiple functions: it predicts risk regions, detects driver sight line position, calculates deviation between them, and decides whether to provide driving support control. By making this single unit multi-functional, the system achieves appropriate adaptability without proportionally increasing overall system complexity.

AI summary
A driving support apparatus in a vehicle, includes: an information acquisition unit configured to acquire peripheral information of the vehicle; a risk prediction unit configured to predict a risk region on the periphery of the vehicle using the peripheral information; a sight line specifying unit configured to specify a position of a sight line of a driver of the vehicle in the peripheral information; and a control unit configured to switch driving support control based on a degree of deviation between the risk region predicted by the risk prediction unit and the position of the sight line specified by the sight line specifying unit.
