Head-Up Display Information Split for Driver-Readable Vehicle Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display systems are cumbersome for drivers as they require passengers to operate mobile terminals, making it difficult for drivers to visually recognize information displayed on these terminals, which complicates the adjustment of information display quantities based on the terminal's installation status.
Innovation Solution
A head-up display control system that includes a HUD device, a terminal holder, a mobile terminal installation detection unit, and a control unit, which adjusts the information display quantity on the HUD device based on the installation status of the mobile terminal, transferring unnecessary display information to the mobile terminal for better driver visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed on a mobile terminal operated by a passenger, then the information can be displayed, but the driver cannot easily visually recognize the information and the operation becomes complicated
Solution Approach 1:
The HUD device acts as an intermediary between the mobile terminal and the driver. It receives display information from the mobile terminal and presents it in a driver-friendly format on the windshield, eliminating the need for the driver to directly operate or view the mobile terminal while maintaining information accessibility
Solution Approach 2:
The display system is segmented into two parts: the mobile terminal handles information management and passenger interaction, while the HUD device handles driver-facing information presentation. This segmentation allows each component to optimize for its specific user's needs
2Loss of information
If the information display quantity on the HUD device is increased, then more information is available to the driver, but the display becomes cluttered and harder to read
Solution Approach 1:
The HUD device displays only a subset of the total information available on the mobile terminal - specifically, only the information relevant to the driver is presented on the HUD, while comprehensive information remains on the mobile terminal for passenger reference
Solution Approach 2:
Different display locations serve different quality requirements: the HUD provides simplified, high-visibility information optimized for driver perception at a glance, while the mobile terminal provides detailed, comprehensive information optimized for passenger review
3Loss of information
If the HUD device displays all necessary information, then the driver has complete information, but the display becomes too complex and occupies excessive space on the windshield
Solution Approach 1:
The system extracts driver-relevant information from the complete set of information on the mobile terminal and displays only that extracted subset on the HUD. This separation removes unnecessary complexity from the driver's view while maintaining full information availability on the mobile terminal

AI summary
A normal information display quantity of a head-up display device is set as a first information display quantity, an information display quantity of the head-up display device after a control unit receives a detection signal of detection of installation of a mobile terminal on a terminal holder from a mobile terminal installation detection unit is set as a second information display quantity, in which the second information display quantity is set to be smaller than the first information display quantity, and at least a part of display information that is displayed in the first information display quantity but is not displayed in the second information display quantity is displayed on the mobile terminal.
