Head-Up Display Virtual Image Vibration Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dangerous situation warning devices experience deviation in the display position of virtual images due to vehicle vibrations, leading to blurring and potential failure in intended display when the vibration exceeds a certain threshold and the viewing distance of the virtual image exceeds a predetermined value.
Innovation Solution
A display system comprising a display unit, a controller, and a vibration information obtaining unit that adjusts the display mode of virtual images based on detected vibrations and viewing distances, using a head-up display configuration with movable and fixed screens to minimize the noticeable deviation of virtual image positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display unit projects a virtual image at a long viewing distance to provide comprehensive driving information, then the information coverage is improved, but the deviation of the display position becomes more noticeable due to vehicle vibrations
Solution Approach 1:
The display mode is dynamically adjusted based on real-time vibration information. When vibration exceeds a threshold, the system changes display parameters such as brightness, size, or position of the virtual image to compensate for the deviation, thereby maintaining display accuracy despite vehicle vibrations
Solution Approach 2:
The system changes physical parameters of the virtual image display (such as brightness, size, or position) in response to vibration conditions. By adjusting these parameters, the system compensates for the increased deviation at long viewing distances while maintaining information coverage
2Device complexity
If the display unit operates without vibration compensation to simplify the system structure, then the device complexity is reduced, but the display position deviation becomes noticeable when vibration exceeds threshold values
Solution Approach 1:
The system incorporates a vibration information obtaining unit that provides real-time feedback on vehicle vibration conditions. Based on this feedback, the controller adjusts the display mode to maintain accuracy, creating a closed-loop system that improves reliability without requiring complex mechanical stabilization mechanisms

AI summary
A display system includes a display unit which displays a virtual image in a target space, a controller which controls display of the display unit, and an obtaining unit which obtains vibration information about vibration applied to the display unit. The controller changes the display mode of the virtual image based on the vibration information, when the vibration exceeds a first threshold value and a viewing distance of the virtual image exceeds a second threshold value.
