Vehicle Windshield Display Object Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-up displays in vehicles are limited in their ability to dynamically adjust information based on the driving situation, often obstructing the driver's view and failing to provide relevant information in real-time, especially when combined with augmented reality features.
Innovation Solution
A display device for vehicles that includes a camera to capture the surroundings, a processor to detect objects and determine their type and position, and a display unit to dynamically adjust the graphic image's position, size, and transparency on the windshield based on the detected information, ensuring that critical information is displayed without obstructing the driver's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a graphic image is displayed on the windshield using augmented reality, then information delivery is enhanced, but the driver's view is obstructed
Solution Approach 1:
The patent applies local quality by displaying graphic images only in specific regions of the windshield that do not overlap with detected objects. The system divides the windshield into multiple display regions and selectively renders graphics only in safe zones, ensuring information is delivered without obstructing the driver's view of critical elements like pedestrians or vehicles.
Solution Approach 2:
The system dynamically adjusts the display regions and graphic image positions based on real-time detection of objects around the vehicle. As objects move or are detected, the safe display regions are recalculated and updated, making the display adaptive to changing driving conditions rather than static.
2Device complexity
If preset information is displayed at a fixed position, then display simplicity is maintained, but adaptability to different driving situations is reduced
Solution Approach 1:
The patent transforms the static display system into a dynamic one by continuously detecting objects around the vehicle and adjusting display regions in real-time. The system determines safe display areas based on detected objects and updates the graphic image positions accordingly, enabling adaptability to different driving situations while maintaining automated operation.
Solution Approach 2:
The system uses feedback from object detection to continuously adjust display regions. The detection results feed into the display control logic, which modifies the safe display areas and graphic positions based on the current driving environment, creating a closed-loop adaptive system.
3Loss of information
If the windshield display area is fully utilized, then information visibility is improved, but the driver's view of surrounding objects is blocked
Solution Approach 1:
The patent applies local quality by identifying and designating specific regions of the windshield as safe display areas where graphic images can be rendered without obstructing views of detected objects. Each detected object creates exclusion zones, and graphics are displayed only in the remaining safe regions, optimizing both visibility and view clarity.
Solution Approach 2:
The system segments the windshield display area into multiple regions based on detected objects. By dividing the windshield into safe and unsafe display zones, the system can maximize information display in safe areas while maintaining unobstructed views of critical objects through the unsafe areas.

AI summary
A display device for a vehicle, and including a camera configured to acquire an image around the vehicle; a display unit configured to display a graphic image on a windshield of the vehicle; and a processor configured to detect at least one object included in the acquired image viewed by a driver of the vehicle, determine information of the detected object comprising a position and size of an area of the windshield in which the object is viewed, and a type of the object, and control the display unit to display the graphic image on an area of the windshield based on the determined information of the object.
