Driving Assist Device Timing Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face a high burden in recognizing upcoming driving scenes, leading to increased driving resources usage, and existing assist devices often provide information at unsuitable times, causing confusion or annoyance.
Innovation Solution
A driving assist device with a processor that infers the timing of a driver's line-of-sight movement or blink to provide assisting information for subsequent travel segments, adjusting the timing based on the quantity of information to reduce driver burden and avoid providing information too early or late, prioritizing navigational and safety-related information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If assisting information is provided in advance for upcoming driving scenes, then driver recognition burden is reduced, but information may be provided too early causing driver annoyance
Solution Approach 1:
The system performs preliminary action by providing assisting information before the driver naturally recognizes the upcoming driving scene. The timing is determined by predicting when the driver will need the information based on driving behavior patterns, allowing the driver to process information at an optimal time rather than overwhelming them too early or too late.
Solution Approach 2:
The system applies dynamics by making the information providing timing adaptable and flexible. The timing is dynamically adjusted based on the quantity of information to be provided and predicted driver recognition patterns, allowing the system to optimize information delivery timing in real-time based on driving conditions and driver state.
2Loss of time
If assisting information is provided too early, then driver has time to understand, but driver feels annoyed by premature information
Solution Approach 1:
The system uses feedback by monitoring driver behavior through cameras and sensors to detect line-of-sight movements and blinks. This feedback is used to predict when the driver will naturally recognize the upcoming scene, allowing the system to adjust information providing timing to coincide with the driver's natural attention cycles, thereby avoiding both premature and delayed information delivery.
3Loss of information
If quantity of assisting information is increased, then comprehensive guidance is provided, but providing timing becomes more difficult to manage
Solution Approach 1:
The system applies segmentation by dividing the upcoming driving course into multiple travel segments and providing assisting information for each segment separately. This allows the system to manage large quantities of information in manageable portions, with each segment's information provided at its own optimized timing based on when the driver will need to recognize that specific scene.

AI summary
A driving assist device is provided, which includes a processor configured to execute an inference module to infer that a timing of a line-of-sight movement or blink detected by a camera near a predicted timing is a timing of a recognizing action of a driver for a subsequent travel segment of a plurality of travel segments that constitute a traveling course of a vehicle, an information providing module to provide the driver with assisting information for the subsequent travel segment before the timing of the recognizing action inferred by the inference module, and a providing timing changing module to change a providing timing of the assisting information according to a quantity of the assisting information.
