Dynamic HUD Restricted Area Adjustment for View Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display systems face challenges in maintaining a large enough display area for information while preventing the driver's front view from being blocked, as they require a significant 'display prohibited' area to avoid obstructing the view, which limits the available display space.
Innovation Solution
A display control apparatus that dynamically adjusts the restricted area for displaying information based on changes in the vehicle's state and environment, using an information acquisition unit, judgment unit, and control unit to modify the area's location, size, and shape in response to changes in driving mode, traffic conditions, and driver arousal levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large display prohibited area is set to prevent blocking the driver's front view, then the driver's front view is protected, but the display allowed area becomes insufficient
Solution Approach 1:
The patent applies dynamics by making the restricted area movable and adjustable rather than fixed. The control unit dynamically changes the position, size, and shape of the restricted area based on detected driving conditions, driver state, and vehicle information. This allows the system to optimize both view protection and display area utilization in real-time根据不同情况
Solution Approach 2:
The patent implements parameter changes by modifying the positional parameters (coordinates), dimensional parameters (width and height), and shape parameters of the restricted area. The system adjusts these parameters based on multiple input factors including driving mode, traffic conditions, and driver arousal level, thereby transforming the static restricted area into an adaptive one that resolves the contradiction between view protection and display space
2Reliability
If the restricted area is fixed to ensure view protection, then safety is maintained, but the system lacks adaptability to different driving situations
Solution Approach 1:
The system transforms the static restricted area into a dynamic one that automatically adjusts its parameters based on real-time detection of driving conditions. The control unit receives information from multiple sensors and continuously modifies the restricted area's position, size, and shape to adapt to different situations while maintaining view protection
Solution Approach 2:
The patent implements feedback mechanisms by detecting driving conditions, driver state, and vehicle information, then using this feedback to adjust the restricted area parameters. The system continuously monitors multiple parameters and makes real-time adjustments, creating a closed-loop control system that balances view protection with display needs across various driving scenarios

AI summary
In a display control apparatus configured to control image data displayed on a predetermined display medium, an information acquisition unit acquires a first information associated with the predetermined matter at a first time and acquire a second information associated with the predetermined matter at a second time after the first time. A determination unit judges whether there is a predetermined change between the first information and the second information. A control unit controls the image data such that in a case where a predetermined change is detected, at least one of parameters including a location, a size, and a shape of a restricted area, in which the displaying of display information including in the image data is limited, is changed so as to achieve the parameter defined in relation to the second information.
