Driver Notification Display Timing for Autonomous Driving Attention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles operating in autonomous driving mode, particularly at level 3 where driver attention is not required, drivers may not consistently notice messages displayed in front of them due to reduced alertness and focus.
Innovation Solution
An apparatus with a looking-direction detection unit and notification unit that displays messages on a display in front of the driver when changes in the vehicle's environment or operations are detected, such as changes in illuminance, atmospheric pressure, or vehicle actions like starting windshield wipers, ensuring the driver's attention is drawn to relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display is disposed in front of the driver to show messages, then the driver can access information, but the driver cannot always recognize the message appropriately in autonomous driving mode
Solution Approach 1:
The notification system dynamically adjusts message display timing and positioning based on real-time detection of driver looking direction. The system transitions from static display to dynamic adaptation, displaying messages only when the driver's attention is forward-facing, thereby resolving the contradiction between information delivery and driver engagement in autonomous mode
Solution Approach 2:
The system implements feedback by continuously monitoring the driver's looking direction and using this information to control message display. The notification unit receives feedback about driver attention state and adjusts message presentation accordingly, ensuring messages are displayed when the driver is capable of recognition while maintaining autonomous driving functionality
2Loss of information
If the driver is required to look ahead carefully, then message recognition improves, but this conflicts with autonomous driving mode where driving operation is unnecessary
Solution Approach 1:
The system performs preliminary detection of the driver's looking direction before displaying messages. By checking driver attention state in advance and only notifying when conditions are appropriate, the system eliminates the need for continuous driver alertness while ensuring message recognition, thus resolving the contradiction between information delivery and operational ease

AI summary
An apparatus for message notification displays a message to be known to a driver of a vehicle on a display unit disposed in front of a driver's seat on which the driver is sitting, when a change in environment around the vehicle causing the driver to turn his/her attention forward, an action of the vehicle that the driver can sense, or operation by the driver of a vehicle-mounted device in a front area of the vehicle is detected, in the case where travel of the vehicle is controlled in autonomous driving mode in which driving operation by the driver is unnecessary, and where a looking direction of the driver is not a direction related to the driving operation.
