In-Vehicle Content Playback Control During Autonomous Driving Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles equipped with autonomous driving functions, drivers may miss important information during a driving operation handover due to continuous content presentation, leading to incomplete recognition of visual or audio content.
Innovation Solution
An information presentation control device that obtains a driver's margin until they take over a driving task, stops content playback at a specific position, and rewinds it from that stop position to ensure smooth recognition of the content during driving changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content continues to be presented without interruption during driving change, then the information presentation is continuous, but the driver may miss important information due to attention shift
Solution Approach 1:
The system performs preliminary actions by detecting the driving change state in advance and determining a stop position for content playback before the driver actually takes over. This allows the content to be paused at an appropriate moment, ensuring the driver can recognize important information without missing it during the transition period
Solution Approach 2:
The system uses feedback by monitoring the driving state and driver attention level to dynamically adjust content presentation. When driving change is detected, the system provides feedback by stopping content at a determined position, and can also rewind content based on the stop position to ensure the driver receives critical information
2Reliability
If content is stopped during playback to ensure driver recognition, then information recognition is improved, but the content presentation continuity is disrupted
Solution Approach 1:
The system determines a stop position for content playback in advance based on detected driving change state, allowing content to be paused at an optimal moment rather than arbitrarily stopping it. This maintains presentation continuity as much as possible while ensuring recognition reliability
Solution Approach 2:
The system dynamically adjusts content presentation based on real-time driving state. The stop position is not fixed but is determined adaptively according to the detected driving change, balancing continuity and recognition reliability through dynamic control
3Reliability
If content is rewound to a previous position after stopping, then the driver can re-review important information, but the total presentation time increases
Solution Approach 1:
The system calculates and determines the stop position and rewind amount in advance based on the detected driving change state. This preliminary calculation ensures that content is rewound only by the necessary amount, avoiding excessive time loss while still allowing the driver to re-review critical information
Solution Approach 2:
The system changes parameters dynamically by adjusting the rewind amount based on the specific driving change detected. Rather than a fixed rewind duration, the system adapts the rewind parameter to match the actual driving context, optimizing the balance between recognition reliability and time efficiency

AI summary
An information presentation control device controlling information presentation to a driver in a vehicle equipped with autonomous driving function is provided. The information presentation control device is configured to: obtain a margin of the driver until an execution of driving change in which the driver takes over the at least partial driving task being performed by the autonomous driving; control a playback mode of a content presented by the information presentation device; stop the content, which is in a playback state, at a stop position in response to the execution of driving change; and set, according to the margin of the driver, a restart position of the content to which the content is rewound from the stop position to restart a playback of the content.
