Dynamic Maneuver Graphics on Windshield HUD
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying and executing preferred driving maneuvers in vehicles can be challenging for operators due to the difficulty in recognizing driving scene locations, leading to distractions and inefficient driving behaviors.
Innovation Solution
A method utilizing a graphic projection display that dynamically registers graphics on the vehicle's windscreen, based on monitored vehicle and road information, to provide operators with visual cues for preferred driving maneuvers, enhancing focus and safety by overlaying graphics onto the driving scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle information is displayed on dashboard instrument gauges, then operator can obtain vehicle operation parameters, but operator attention is diverted from the driving scene
Solution Approach 1:
The patent projects vehicle information and driving scene overlays from the dashboard plane onto the windshield plane, utilizing a different spatial dimension (the windshield transparency dimension) to display information without requiring operator head movement or attention shift from the driving scene
Solution Approach 2:
The patent introduces a head-up display system with projection optics as an intermediary between the dashboard information source and the operator's field of view, allowing information to be transmitted without direct line-of-sight to traditional gauges
2Loss of information
If operator looks at dashboard gauges for driving information, then vehicle operation parameters are visible, but driving efficiency decreases due to distraction
Solution Approach 1:
The patent merges the driving scene view with vehicle information and maneuver guidance overlays into a single composite display on the windshield, allowing simultaneous access to both environmental awareness and operational parameters without separation into different viewing zones
Solution Approach 2:
By projecting information onto the windshield in the operator's forward field of view rather than on dashboard gauges requiring peripheral or downward glances, the system maintains driving efficiency while providing comprehensive information
3Ease of operation
If traditional head-up display projects information on windshield, then operator focus is maintained, but identification of driving scene location for maneuvers remains difficult
Solution Approach 1:
The system introduces a camera capturing the driving scene view as an intermediary, processing the visual information to identify and mark maneuver locations, then overlaying these markers on the windshield display to guide the operator to specific locations without requiring manual scene analysis
Solution Approach 2:
The patent uses color-coded graphics and visual markers overlaid on the driving scene to highlight maneuver locations and types, making specific locations and actions easily distinguishable through color differentiation in the head-up display
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces operator distraction and improves driving efficiency by providing clear, dynamic visual cues for preferred maneuvers, enhancing both performance and safety, especially in racing applications.
Implementation Method 1
Head-up displays project light upon a screen and the light is converted into a viewable display upon the screen
Data Source
AI summary
A method to dynamically register a graphic on a driving scene of a source vehicle utilizing a graphic projection display includes monitoring source vehicle information and monitoring road information. A preferred driving maneuver and a driving scene location of the preferred driving maneuver are identified based on the monitored source vehicle information and the monitored road information. A graphic exemplifying the preferred driving maneuver is determined and a location of the graphic is dynamically registering upon the graphic projection display corresponding to the driving scene. The dynamically registered location is based on the driving scene location of the preferred driving maneuver. The graphic is displayed upon the graphic projection display.
