Driver Monitoring Notification Control for Reduced Alert Annoyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving systems often annoy drivers with excessive attention-seeking notifications when they cannot continue automated driving control, leading to discomfort.
Innovation Solution
A notification control device that determines whether the driver is recognized by a camera, and if not, executes relaxed notification processing through sound and display outputs, reducing annoyance by switching to a less intrusive mode when certain conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If attention-seeking notifications are executed when driver recognition fails during automated driving, then driver safety is improved, but driver comfort deteriorates due to excessive notifications
Solution Approach 1:
The notification control device changes notification parameters (output mode, frequency, intensity) based on the recognition state and driving conditions. When driver recognition fails, the system adjusts notification parameters to balance safety alerts with driver comfort, avoiding excessive or intrusive notifications while maintaining necessary safety communications.
Solution Approach 2:
The notification system dynamically adapts its behavior based on real-time conditions including driver recognition state, vehicle speed, and driving environment. The notification control device switches between different notification modes (visual, auditory, haptic) and adjusts notification frequency dynamically, making the system responsive to changing conditions rather than using fixed notification patterns.
2Reliability
If normal notification processing is executed when driver is not recognized, then driver attention is ensured, but driver comfort deteriorates due to intrusive notifications
Solution Approach 1:
The notification control device applies different notification qualities to different situations. Instead of using uniform notification methods, the system selects appropriate notification types (subtle vs. prominent) based on the specific driving context and recognition state, providing localized optimization of notification characteristics for each situation.
Solution Approach 2:
The system changes notification parameters such as output intensity, duration, and modality based on driving conditions. When the driver is not recognized but conditions allow for relaxed notifications, the system adjusts parameters to reduce intrusiveness while still maintaining driver attention when necessary.
3Ease of operation
If relaxation notification processing is applied, then driver comfort is improved by reducing annoyance, but notification effectiveness may be reduced
Solution Approach 1:
The notification control device dynamically adjusts notification intensity based on real-time assessment of driver state and driving conditions. The system monitors whether relaxed notifications are sufficient and escalates to more prominent notifications when safety concerns arise, creating a dynamic balance between comfort and effectiveness.
Solution Approach 2:
The system uses feedback from driver recognition cameras and driving condition sensors to continuously adjust notification strategies. When relaxed notifications are applied, the system monitors driver response and system state to determine whether escalation to stronger notifications is needed, ensuring notification effectiveness is maintained through active monitoring and adjustment.

AI summary
When a driver of a vehicle is not recognized by a driver monitoring camera during autonomous driving, it is determined whether a notification relaxation condition is satisfied based on a driver status and a driving status of the vehicle. When it is determined that the notification relaxation condition is not satisfied, normal notification processing is executed in which an output device notifies the driver in a first manner. When it is determined that the notification relaxation condition is satisfied, relaxation notification processing is executed in which the output device notifies the driver in a second manner that is more relaxed than the first mode.
