Vehicle Display Control for Windshield Projection and Screen Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers must frequently look away from the road to view vehicle information displayed on the instrument panel, leading to safety concerns due to distraction from driving.
Innovation Solution
A method for controlling a vehicle's display device that dynamically adjusts display mode and content based on driving parameters, such as light intensity and obstacle information, allowing information to be displayed on the windshield or dashboard without requiring the driver to look down, using a projection or screen display mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle information is displayed on the instrument panel or central control screen, then the driver can access driving information, but the driver must look down which causes distraction and reduces driving safety
Solution Approach 1:
The patent projects display content from the traditional 2D instrument panel or central control screen onto the windshield, transforming the display dimension. This allows information to be presented in the driver's forward field of view rather than requiring downward glances, effectively resolving the contradiction between safety and information accessibility
Solution Approach 2:
The patent introduces a projection system as an intermediary between the vehicle's information system and the driver. This projection mechanism acts as a mediator that delivers driving information directly into the driver's line of sight without requiring the driver to shift attention to separate display locations, thereby maintaining both safety and accessibility
2Reliability
If projection display mode is used on the windshield, then driving safety is improved by keeping eyes on the road, but the display may be affected by light intensity conditions
Solution Approach 1:
The patent implements dynamic switching between projection display mode and screen display mode based on real-time light intensity detection. The system adapts its display characteristics to environmental conditions, using projection in suitable lighting conditions and switching to traditional screen display when light conditions are unfavorable, thus maintaining both safety and environmental adaptability
Solution Approach 2:
The patent changes display parameters (display mode, brightness, content) based on detected light intensity conditions. By adjusting these parameters according to environmental lighting, the system maintains effective display performance across varying conditions while preserving the safety benefits of windshield projection when applicable

AI summary
The invention relates to a method for controlling a display device of a vehicle, a medium and a display device, which relates to a field of vehicle technologies. The display device is configured to acquire data information sent by an external terminal by communicating with the external terminal. The method includes: acquiring a driving parameter collected by the vehicle; determining a target display mode and a target display content based on the driving parameter, wherein the target display mode comprises at least one of a projection display mode or a screen display mode; and displaying the target display content based on the target display mode. In this way, the driver may not only view vehicle information without looking down at the central control panel or the instrument panel, but also assist the driver in driving the vehicle better by dynamically adjusting the display mode and the display content.
