Vehicle Notification Control by Mobile Terminal Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conditional automated driving scenarios, drivers may overlook important vehicle-related notifications due to receiving all notifications in the same manner, leading to a decrease in interest and increased likelihood of missing critical alerts.
Innovation Solution
A notification system that varies the controllability of a mobile terminal by a driver based on the urgency of the notification information, such as requiring a confirmation button press for high-urgency notifications, ensuring important alerts are not missed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all notifications are transmitted to the mobile terminal in the same way, then the driver can receive all notification information, but the driver may overlook important notifications and lose interest
Solution Approach 1:
The notification system segments notification information based on urgency levels, dividing notifications into different categories (e.g., high urgency, medium urgency, low urgency). This segmentation allows the system to apply different transmission strategies to different notification types, ensuring that important notifications are delivered reliably while less important ones can be delivered through standard channels.
Solution Approach 2:
The system applies local quality by varying the transmission characteristics of notifications based on their specific urgency level and content. High-urgency notifications receive enhanced transmission treatment (such as repeated notifications, different delivery channels, or immediate delivery), while low-urgency notifications use standard transmission methods. This ensures that the quality of notification delivery matches the importance of the information.
2Ease of operation
If the mobile terminal is fully controllable by the driver during automated driving, then the driver can perform tasks other than driving operations, but the driver may be distracted from important vehicle notifications
Solution Approach 1:
The system dynamically adjusts the controllability of the mobile terminal based on the urgency of vehicle notifications. When a high-urgency notification is detected, the system temporarily restricts mobile terminal operations to ensure the driver's attention is focused on the vehicle. When no urgent notifications are present, the mobile terminal remains fully accessible for non-driving tasks. This dynamic adjustment balances driver flexibility with notification reliability.
Solution Approach 2:
The system takes preliminary anti-action by proactively restricting mobile terminal controllability before the driver can become distracted from important notifications. When an urgent notification is detected, the system preemptively limits access to the mobile terminal, preventing potential distraction before it occurs. This ensures that critical vehicle information receives the driver's attention.
3Reliability
If the driver is required to respond to all notifications, then important notifications can be ensured to be noticed, but the driver may experience notification fatigue
Solution Approach 1:
The notification system segments notifications by urgency level, creating distinct categories such as high-urgency, medium-urgency, and low-urgency notifications. This segmentation allows the system to apply different response requirements to different notification types. High-urgency notifications require driver response through confirmation buttons or voice commands, while low-urgency notifications can be acknowledged automatically or deferred, reducing overall complexity.
Solution Approach 2:
The system changes the response parameter requirements based on notification urgency. For high-urgency notifications, the system requires explicit driver response (such as pressing a confirmation button or providing a voice command). For medium-urgency notifications, the system may accept automated acknowledgments. For low-urgency notifications, no immediate response is required. This parameter change approach ensures reliable response to critical notifications while simplifying handling of less important ones.

AI summary
A notification system includes a mobile terminal configured to receive, and to perform notification of, notification information regarding a vehicle, and a vehicle control device that is configured to generate the notification information for a driver of the vehicle, and to transmit the notification information to the mobile terminal, in which the vehicle control device includes one or more processors configured to perform control in which notification of the notification information is made to the mobile terminal, while varying a range of the mobile terminal that is controllable by the driver until a predetermined condition is satisfied, in accordance with an urgency of the notification information.
