Vehicle Display Control for Autonomous-to-Driver Handover Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to provide clear and situation-dependent notifications when transitioning from traffic congestion autonomous driving to driver-required driving, necessitating improved display control to enhance driver understanding.
Innovation Solution
A vehicle display control system and method that includes a display control unit and situation specification unit to adjust display timing and content based on the vehicle's situation, ensuring notifications are clear and relevant during transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous driving operation is executed during traffic congestion, then driving automation is improved, but driver awareness and control are reduced
Solution Approach 1:
The system performs preliminary actions by displaying exchange notification information to the driver before the autonomous driving operation is fully activated or before switching to driver-required operation. This advance notification ensures the driver is aware of the upcoming transition and maintains situational awareness, resolving the contradiction between automation and driver awareness.
Solution Approach 2:
The system implements feedback by continuously monitoring the traffic congestion situation and providing real-time notification information to the driver about the autonomous driving status and potential switches to driver-required operation. This feedback loop maintains driver awareness while allowing autonomous operation to proceed under appropriate conditions.
2Loss of information
If driving operation exchange notification is displayed, then driver understanding is improved, but notification timing and relevance may be inconsistent
Solution Approach 1:
The system applies dynamics by making the notification display adaptive rather than static. The display control unit dynamically adjusts the notification information based on the current traffic congestion situation, ensuring that the most relevant information is presented at the appropriate time. This resolves the contradiction by making the notification system versatile enough to adapt to different driving scenarios while maintaining clear driver understanding.

AI summary
In a vehicle in which a traffic congestion autonomous driving operation and a driver required driving operation are executable, a display relating to a driving operation exchange from the traffic congestion autonomous driving operation to the driver required driving operation is performed when a switching from the traffic congestion autonomous driving operation to the driver required driving operation is requested, a situation of the vehicle is specified such that the switching from the traffic congestion autonomous driving operation to the driver required driving operation is requested, and at least one of a timing of the display and a content of the display relating to the driving operation exchange is changed according to the situation.
