Windshield AR Image Output for Lane Guidance Without Driver Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image output devices in vehicles lack the ability to effectively provide augmented reality information, such as lane guidance and driving information from other vehicles, in a manner that enhances driver convenience and safety without distracting the driver.
Innovation Solution
An image output device and method that uses a controller to receive and process real-time images from the vehicle's forward path and other vehicles on the route, generating carpet images to indicate lanes and superimposing them on the output for augmented reality display, allowing for intuitive lane guidance and sharing of driving information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented reality information is provided through traditional displays, then driver information access is improved, but driver distraction increases
Solution Approach 1:
The patent projects augmented reality information onto the windshield surface, transforming the display dimension from a flat panel to a three-dimensional spatial overlay that appears to float in the driver's field of view. This allows information to be presented without requiring the driver to shift gaze to a separate display location, thereby reducing distraction while improving information access.
Solution Approach 2:
The windshield serves as an intermediary medium between the information source and the driver's eyes. By projecting images onto the transparent windshield surface, the system mediates information delivery in a way that maintains the driver's natural viewing direction while superimposing relevant data such as lane guidance and vehicle status information.
2Loss of information
If multiple information sources are integrated, then driving information completeness is improved, but system complexity increases
Solution Approach 1:
The patent combines multiple information sources including forward camera images, lane recognition data, and inter-vehicle communication data into a single integrated augmented reality display on the windshield. This merging of multiple data streams into one unified presentation interface improves information completeness while managing system complexity through consolidated processing and display architecture.
Solution Approach 2:
The windshield display system performs multiple functions simultaneously: it displays lane guidance information, shows vehicle status data, presents navigation instructions, and communicates with other vehicles. This multi-functionality allows a single system to handle diverse information requirements without proportionally increasing complexity, as the same hardware platform supports various information types and display modes.
