Vehicle Display Layout for Sequential Self-Driving Action Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices for self-driving vehicles do not adequately inform occupants about subsequent planned actions, leading to anxiety as occupants cannot intuitively understand the vehicle's direction or destination.
Innovation Solution
A display device that projects information onto the windshield and displays planned actions on an instrument panel, with the next action as a primary plan and subsequent actions as secondary plans, arranged in a sequence to be executed, allowing occupants to intuitively understand the flow of actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the next planned action is displayed by a HUD device, then the immediate action information is provided, but subsequent planned actions cannot be ascertained and occupants cannot intuitively understand the vehicle's direction or destination
Solution Approach 1:
The display system is segmented into two distinct parts: a HUD device for displaying the primary planned action (next action) and a meter panel for displaying secondary planned actions (subsequent actions). This segmentation allows comprehensive information provision while maintaining clear functional differentiation between the two display devices, reducing information loss without creating a single complex display system.
2Loss of information
If multiple planned actions are displayed using a single display device, then all action information is provided, but the intuitive understanding of action sequence and flow is reduced
Solution Approach 1:
The meter panel acts as an intermediary display device that complements the HUD device. While the HUD shows the primary planned action, the meter panel displays secondary planned actions in a vertical list format that is easier to read and comprehend. This intermediary device provides comprehensive information while maintaining intuitive understanding through its specific display characteristics.
3Loss of information
If planned actions are displayed without showing the sequence, then information is provided, but occupants cannot understand the flow of actions from current to future states
Solution Approach 1:
The system displays secondary planned actions in advance on the meter panel, showing the sequence of future actions before they are executed. This preliminary display of action sequences allows occupants to understand the planned flow of operations, reducing anxiety and increasing trust in the self-driving system's reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces occupant anxiety by clearly displaying multiple planned actions, enabling intuitive understanding of the vehicle's actions and their sequence, thereby enhancing trust in self-driving vehicles.
Implementation Method 1
displays information by projecting projection light that is used to display information onto the front windshield glass

AI summary
A display control device for a vehicle is provided. The display control device includes a processor configured to display a primary plan on a first display and a secondary plan on a second display. The primary plan is to be performed next after a vehicle action currently being performed, and the secondary plan is to be performed subsequently to the primary plan. The first display may be provided on an upper side of the second display. The first display may be a head-up display, and the second display may be a meter panel.
