Vehicle Display Layout for Autonomous-to-Manual Plan Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices do not effectively communicate changes in planned operations from autonomous driving to manual driving, potentially confusing occupants about the change in driving mode.
Innovation Solution
A vehicle display device that displays alternative plans alongside scheduled plans, with the option to change from autonomous driving to manual driving, and highlights these changes in a distinct manner, such as using different colors or positions on the display, to inform occupants of potential mode switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If autonomous driving control is displayed as the scheduled operation, then the display shows the planned operation, but the occupant cannot understand when the operation cannot be performed due to road conditions or other factors
Solution Approach 1:
The display device shows alternative plans in advance before the scheduled operation is executed. This allows occupants to know beforehand that a plan might be switched from autonomous to manual driving, preventing confusion when the change occurs
Solution Approach 2:
An alternative plan is introduced as an intermediary element between the current scheduled plan and potential future plans. This intermediary display element communicates the possibility of plan changes without requiring complex additional interfaces or controls
2Reliability
If the notation of autonomous driving control is changed to manual driving notation, then the display reflects the actual driving mode, but the occupant may not understand the change because the operation notation remains unchanged
Solution Approach 1:
The display device applies different visual characteristics to different parts of the plan notation. Specifically, alternative plans are displayed with distinct visual attributes (such as different colors, styles, or positions) to differentiate them from scheduled plans, while keeping the overall notation structure familiar and easy to understand
Solution Approach 2:
The display device uses color changes to indicate the status of different plans. Scheduled plans are displayed in one color/style while alternative plans are displayed in a different color or visual style, providing immediate visual feedback about plan change possibilities without complicating the notation

AI summary
A vehicle display device includes: a display section that is provided inside a vehicle cabin and that includes, at a display area, a specific display region that displays plural plans scheduled to be implemented with respect to a vehicle, arranged in an order in which the plural plans are scheduled to be implemented; and a control section configured to cause display of, between a first plan, which is one plan among the plural plans, and a second plan, which is scheduled to be implemented next after the first plan, at the specific display region, an alternative plan that has a possibility of being implemented instead of the first plan.
