Vehicle HUD and Meter Panel Layout for Planned Action Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems for self-driving vehicles do not effectively communicate the vehicle's subsequent planned actions to occupants, 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 intuitively understood by the occupant, using a HUD device and meter panel to provide clear visualization.
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 to the occupant, but subsequent planned actions cannot be ascertained and the occupant cannot intuitively understand whether the vehicle is traveling in a direction or to a destination desired by the occupant
Solution Approach 1:
The display system is segmented into two distinct components: 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 each display device to have a specific function, providing comprehensive action information while maintaining clear and simple individual device designs.
2Ease of operation
If multiple planned actions are displayed using a single display device, then all action information is provided, but the occupant cannot intuitively understand the flow and sequence of actions
Solution Approach 1:
The meter panel acts as an intermediary display device that complements the HUD device. While the HUD displays the primary planned action, the meter panel displays secondary planned actions in sequential order, creating a visual flow that helps the occupant intuitively understand the sequence of actions without losing information about multiple planned actions.
Solution Approach 2:
The system transitions from a single-dimension display (HUD only) to a multi-dimensional display system by adding the meter panel as a second display dimension. This allows information to be distributed across different spatial and functional dimensions, with the HUD providing forward-looking action information and the meter panel providing sequential action context.
3Measurement precision
If the HUD device displays all planned actions, then complete information is provided, but the display becomes cluttered and the occupant cannot quickly identify the next action
Solution Approach 1:
The system extracts and separates the display of primary planned actions from secondary planned actions. The HUD device exclusively displays the primary planned action (next action) with high clarity, while the meter panel extracts and displays the secondary planned actions. This extraction ensures the next action is immediately identifiable without clutter while still providing complete information about subsequent actions.
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, allowing intuitive understanding of the vehicle's actions and their sequence, enhancing transparency and reducing uncertainty during self-driving.
Implementation Method 1
displays information by projecting projection light that is used to display information onto the front windshield glass so that the information appears superimposed on scenery visible in front of the vehicle
Data Source
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.
