Driver Notification Persistence Based on Alert Urgency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conditional automated driving scenarios, drivers may overlook important notifications due to uniform notification methods, leading to a higher likelihood of missing critical alerts related to vehicle safety and operations.
Innovation Solution
A notification system that adjusts the ending condition for notifications based on their urgency, using a mobile terminal to notify drivers until a specific condition is met, including requiring vehicle operation or confirmation, to emphasize the importance of high-priority alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all notifications are given to the driver in the same way, then the notification system is simple and easy to operate, but the driver may find the notifications bothersome and lose interest, leading to overlooking important notifications
Solution Approach 1:
The notification system applies different notification methods to different notification items based on their urgency level. Important notifications with high urgency are delivered through multiple channels (voice, display, haptic feedback) while less important notifications use simpler methods. This local differentiation ensures critical information stands out without making the entire system overly complex.
Solution Approach 2:
The system changes notification parameters such as repetition count, notification method type, and delivery timing based on the urgency parameter of each notification item. High-urgency notifications trigger more persistent and varied delivery methods, while low-urgency notifications use standard single-delivery methods, allowing the system to adapt its behavior dynamically.
2Reliability
If the notification system uses persistent notification until ending condition is met, then important notifications are less likely to be overlooked, but the driver may experience increased disturbance and annoyance
Solution Approach 1:
Persistent notification behavior is applied selectively only to high-urgency notification items that require driver response, while low-urgency notifications use standard single-delivery methods. This localized application of persistence ensures critical alerts are noticed without unnecessarily disturbing the driver during routine notifications.
Solution Approach 2:
The notification system monitors driver responses and automatically adjusts notification persistence based on whether the ending condition (driver response) has been met. If the driver responds to a high-urgency notification, the persistent notification stops; if not, the notification continues with increased intensity, creating a feedback loop that balances reliability with driver comfort.
3Reliability
If the notification system requires driver response for high urgency notifications, then the driver's attention is ensured, but the driver's operational time is increased
Solution Approach 1:
The system prepares multiple notification delivery methods in advance for high-urgency items, so that when a notification is issued, the driver receives it through the most effective channel immediately (voice, display, or haptic feedback simultaneously). This preliminary preparation of delivery channels reduces the time needed for the driver to perceive and respond to critical notifications.
Solution Approach 2:
For high-urgency notifications requiring driver response, the system employs periodic repetition at optimized intervals rather than continuous notification. This periodic delivery ensures the driver notices the notification without creating constant disturbance, balancing response assurance with minimal time loss.
Data Source
AI summary
A notification system includes a mobile terminal and a processor. The mobile terminal receives notification information for a driver of a vehicle and notifies the driver of the notification information. The processor generates the notification information and transmits the notification information to the mobile terminal. The processor causes the mobile terminal to notify the driver of the notification information until an ending condition for ending notification is satisfied. The processor changes the ending condition depending on urgency of the notification information.
