Vehicle Display Control for Automatic Driving Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information display systems for automatic driving vehicles often provide unnecessary information to occupants, which can be distracting and reduce interest in the travel route, and fail to effectively convey the current driving mode to the occupant.
Innovation Solution
An information display device and method that arranges event point information relevant to the route in order from the current position to the destination, reducing information during automatic driving and selectively displaying relevant details such as toll road exits, stopover points, and road connections, while allowing occupant input to adjust the displayed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information on all event points is displayed during automatic driving, then complete route information is provided, but information that is less of interest to occupants is displayed causing distraction
Solution Approach 1:
The patent extracts and removes event point information that is less relevant to occupants during automatic driving from the display. The display control unit selectively hides routine event points (such as regular road intersections or non-critical locations) while maintaining display of important event points (such as exits, toll gates, or locations requiring manual intervention), thereby reducing distraction while preserving essential route information.
Solution Approach 2:
The patent applies different display qualities to different event points based on their relevance. Important event points are displayed with full information, while less important event points are hidden or displayed with reduced information during automatic driving. This local differentiation allows the system to provide complete route information overall while minimizing distracting details at specific locations.
2Loss of information
If detailed event point information is displayed, then occupants have complete route awareness, but the display becomes cluttered and less readable
Solution Approach 1:
The system extracts only the essential event point information needed for route awareness and displays it, removing redundant or less critical details. This extraction approach maintains complete route awareness while significantly reducing display clutter and improving readability.
3Loss of information
If all event points are displayed during automatic driving, then no information is lost, but the occupant cannot easily understand the current automatic driving mode
Solution Approach 1:
The patent extracts and highlights specific event points that are relevant to understanding the automatic driving mode, such as points where manual intervention may be needed or where the automatic driving system makes critical decisions. By selectively displaying these key event points rather than all event points, the system maintains information completeness while improving the occupant's ability to recognize and understand the current driving mode.

AI summary
An information display device includes a display unit that displays a point guidance image in which information relevant to event points included in a route to a destination is arranged in an order from a current position to the destination, and a display control unit that reduces information relevant to the event points when automatic driving for automatically controlling at least one of acceleration and deceleration, and steering of the vehicle is executed, as compared with a case in which the automatic driving is not executed.
