Vehicle Warning Display Layout for Distance-Based Driver Attention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles are equipped with multiple display devices that struggle to effectively transmit necessary information to drivers with optimal timing and visibility, especially with the increasing amount and variety of information being displayed.
Innovation Solution
A display system comprising a first display device that displays images at a closer distance to the driver's visual line and a second display device that displays images at a greater distance, along with a display controller that enhances recognizability by moving warning images between the two display regions based on specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple display devices are arranged in multiple places to display information, then the amount and variety of information transmissible to the driver is increased, but the ability to transmit necessary information with necessary timing and good visibility deteriorates
Solution Approach 1:
The display system is segmented into multiple display devices (first display device 20 and second display device 30) positioned at different distances from the driver's visual line. Each display device is responsible for displaying specific types of information appropriate to its viewing distance, with the closer display handling immediate warnings and the farther display handling supplementary information.
Solution Approach 2:
The system dynamically moves warning images between the first display region 8 and second display region 9 based on warning levels and timing. The display controller transitions warning images from the farther display region to the closer display region when urgent attention is needed, and vice versa for less critical information, optimizing information delivery based on real-time conditions.
2Ease of operation
If display devices are positioned at different distances from the driver's visual line, then information can be displayed at varying visibility levels, but the complexity of managing multiple display regions increases
Solution Approach 1:
The display controller monitors warning levels and driver attention states, then provides feedback by adjusting the position and content displayed in each region. When a high warning level is detected, the system automatically prioritizes displaying that information in the first display region 8 (closer to visual line), ensuring critical information receives appropriate attention.
Solution Approach 2:
The system prepares display content in advance by pre-positioning warning images in the second display region 9 before they need to be highlighted. This preliminary action allows smooth transitions and ensures that when a warning becomes critical, the information is already prepared and can be quickly moved to the first display region 8 without delay.
3Loss of time
If warning images are moved between display regions based on warning levels, then information transmission timing is optimized, but the complexity of the control process increases
Solution Approach 1:
The system changes the positional parameter of warning images between display regions based on the warning level parameter. When the warning level increases beyond a threshold, the system automatically transitions the warning image from the second display region 9 to the first display region 8, creating a clear, parameter-driven control logic that simplifies decision-making despite multiple display regions.

AI summary
A display system includes: a first display device displaying an image in a first region to cause the image to be visually recognized in a position at a first distance from a visual line of a driver of an auto-vehicle; a second display device displaying an image in a second region to cause the image to be visually recognized at a second distance greater than the first distance from the visual line; and a display controller displaying a warning image in the second region if a first condition is satisfied, moving the warning image to display a warning image in the first region if a second condition in which a warning level is higher than that of the first condition is satisfied after the first condition is satisfied, then updating the warning image to an updated warning image, and then moving the updated warning image to the second region.
