Autonomous Vehicle Control Transfer Display Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for autonomous vehicle operation assistance lack effective management of information presentation to ensure safe and efficient transfer of control between autonomous and driver control, particularly in scenarios requiring urgent or advisory notifications.
Innovation Solution
A vehicle system that includes primary and secondary graphical displays, along with a processor, to identify and present vehicle operation assistance information, determining urgency and immanence to control display content, ensuring timely and relevant information is conveyed to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle operation assistance information is presented during autonomous vehicle control transfer, then driver situational awareness is improved, but driver distraction may increase
Solution Approach 1:
The patent applies local quality by differentiating information presentation based on urgency level. Critical information during control transfer is presented with higher prominence (e.g., audio alerts, prominent display) while less urgent information uses subtler presentation methods. This ensures important information is noticed without uniformly presenting all information at maximum intensity that would cause distraction.
Solution Approach 2:
The system dynamically adjusts information presentation based on real-time assessment of driver state, vehicle context, and imminence of control transfer. The presentation modality, timing, and content are adapted dynamically to balance information delivery with minimization of distraction, rather than using a static presentation approach.
2Loss of information
If multiple display portions are used to present vehicle operation assistance information, then information visibility is improved, but device complexity increases
Solution Approach 1:
The patent segments information presentation across multiple display portions (e.g., primary display for critical information, secondary display for supplementary information). This segmentation allows important information to be visible without cluttering the entire display system, improving information visibility while managing complexity through functional division.
Solution Approach 2:
The system utilizes multiple spatial dimensions (different display locations, screen real estate areas) to present information hierarchically. Critical information appears in prominent locations while secondary information is placed in less prominent areas, effectively using spatial dimensionality to organize information without increasing functional complexity.
3Loss of time
If vehicle operation assistance information is presented with high urgency, then response time is improved, but information accuracy may be compromised
Solution Approach 1:
The system performs preliminary assessment of information accuracy and relevance before presenting with high urgency. The processor evaluates the imminence of control transfer and the reliability of assistance information before triggering urgent presentation, ensuring that time-critical information is both accurate and appropriate for urgent delivery.
Solution Approach 2:
The system incorporates feedback mechanisms to verify information accuracy before urgent presentation and to monitor driver response to urgent alerts. This feedback loop ensures that high-urgency information is validated and that the system can adjust future information delivery based on driver behavior and system performance.

AI summary
A vehicle implementing vehicle operation assistance information management for autonomous vehicle control transfer may identify a vehicle operation assistance information item indicating a location of an expected vehicle operation control transfer, and, in response to a determination that an immanency for the vehicle operation assistance information item is within a maximum relevant immanence, present a representation of the vehicle operation assistance information item, which may include, in response to a determination that an urgency for the vehicle operation assistance information item indicates a warning urgency or an advisory urgency, controlling the primary graphical display portion and the secondary graphical display portion to present a graphical representation of the vehicle operation assistance information item, such that the primary graphical display portion presents a first portion of the graphical representation and the secondary graphical display portion presents a second portion of the graphical representation.
