Driver Activity Notification for Automated Driving Level Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of systems that effectively notify drivers of the permissible activities during automated driving, leading to safety concerns as drivers are unsure of what activities are allowed based on the current automated driving level, especially when levels change during travel.
Innovation Solution
An information processing device and system that acquires the current automated driving level and provides a list of allowable activities to the driver, notifying them of changes in permitted actions as the driving level transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated driving level is increased to allow more driver activities, then driver comfort and productivity are improved, but safety control becomes more difficult
Solution Approach 1:
The system continuously monitors the current automated driving level and provides real-time feedback to the driver about which activities are permitted. The notification unit informs drivers of their allowable activities based on the current driving level, creating a closed-loop feedback mechanism that maintains safety while enabling appropriate driver freedom.
Solution Approach 2:
The system dynamically adjusts the notification of allowable activities based on changes in automated driving level. When the driving level transitions, the notification unit updates the permitted activities accordingly, making the system adaptable to varying operational conditions rather than static.
2Adaptability or versatility
If automated driving level changes during travel, then system adaptability to different road conditions is improved, but driver awareness and control become problematic
Solution Approach 1:
The notification unit proactively informs the driver of allowable activities before or at the moment of driving level transition. By providing advance or timely notification of what activities are permitted under the new driving level, the system prepares the driver for the changed conditions and prevents information loss.
Solution Approach 2:
The system provides continuous feedback to the driver about the current driving level and corresponding allowable activities. This feedback mechanism ensures the driver remains aware of their permitted actions even as the system adapts to different road conditions through driving level changes.
3Reliability
If driver activities are restricted to ensure safety, then driving safety is improved, but driver comfort and satisfaction deteriorate
Solution Approach 1:
The system applies different activity restrictions based on the specific automated driving level. Rather than uniformly restricting all activities, the notification unit tailors the allowable activities to match the current driving level, providing localized quality control that balances safety requirements with driver comfort for each operational mode.

AI summary
A configuration for notifying a driver of an allowable activity for the driver according to an automated driving level is realized. The automated driving level of automated driving being executed by a mobile device is acquired, and the driver is notified of the allowable activity for the driver according to the acquired automated driving level. The control unit acquires an automated driving level-corresponding allowable activity list in which the automated driving level and the allowable activity are associated with each other from an external server or a storage unit, refers to the automated driving level-corresponding allowable activity list, acquires the allowable activity corresponding to the automated driving level, and notifies the driver of the acquired allowable activity. Furthermore, in a case where the automated driving level of the mobile device is changed, a difference between the allowable activities according to the change of the automated driving level is analyzed, and in a case where there is a difference, notification of difference information is provided.
