Vehicle Control Device for Autonomous to Manual Driving Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During autonomous driving, occupants may continue applying makeup when a handover notification is given, leading to potential issues with recognizing their readiness for manual driving, which can necessitate vehicle stopping control.
Innovation Solution
A vehicle control device with a processing unit that performs a makeup ending process when switching from autonomous to manual driving, including closing sun visor mirrors, erasing mirror images, and prohibiting mirror usage to inhibit makeup continuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle switches from autonomous driving to manual driving, then the driving state transitions smoothly, but the occupant may continue makeup activities and not recognize readiness for manual driving
Solution Approach 1:
The system performs preliminary actions by closing the sun visor mirror lid or erasing the mirror image before the handover is complete, preventing the occupant from continuing makeup activities and ensuring readiness for manual driving without interrupting the transition process
Solution Approach 2:
The system applies preliminary anti-action by prohibiting mirror usage through lid closure or image erasure, counteracting the occupant's tendency to continue makeup activities during the critical handover period when attention should be on the road
2Ease of operation
If the occupant is allowed to use the mirror during autonomous driving, then makeup application is convenient, but the occupant may remain engaged in makeup even after handover notification
Solution Approach 1:
The system dynamically changes the availability of the mirror based on driving state transitions. During autonomous driving, the mirror is accessible for makeup application. Upon handover notification, the system automatically closes the lid or erases the image, dynamically switching from a permissive state to a restrictive state to ensure handover readiness
3Loss of information
If the handover notification is given to the occupant, then the occupant is notified of switching, but the occupant may not respond due to continued makeup activities
Solution Approach 1:
The system implements feedback by monitoring whether the occupant interacts with the mirror after handover notification. If the mirror remains open or the image is still displayed when it should be closed, the system can issue additional notifications or take corrective actions, ensuring the occupant responds to the handover request

AI summary
In a vehicle in which a driving state is switchable between autonomous driving and manual driving, it is determined whether an occupant is applying makeup. When it is determined that the occupant is applying makeup at a time of switching of the driving state from autonomous driving to manual driving, a process of closing a lid of a mirror provided on a sun visor of the vehicle is performed as a makeup ending process of ending makeup by the occupant.
