Windshield Display for Vehicle Hazard Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information presenting systems divert the driver's focus from the road to the windshield, leading to potential oversight and delayed reaction to dangerous objects due to the need for significant focal adjustments.
Innovation Solution
An information presenting apparatus and method that displays vision information representing a vehicle's run anticipation track, shifting the focus from the direction of movement to the location of a detected dangerous object, reducing the need for large focal adjustments and enabling quicker reaction times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If warning information is displayed on the windshield, then the dangerous object is highlighted for the driver, but the driver must perform focal adjustment from the road to the dangerous object which causes delayed reaction and potential oversight
Solution Approach 1:
The patent uses the windshield display as an intermediary to project dangerous object information directly into the driver's field of view. By displaying the dangerous object's image or representation on the windshield, the system creates an intermediate visual channel that allows the driver to perceive hazards without completely shifting focus from the road, thereby reducing focal adjustment time while maintaining reliable hazard detection
Solution Approach 2:
The patent transforms the traditional audio or dashboard warning into a visual dimension by projecting information onto the windshield. This dimensional change allows the driver to process hazard information in the same visual plane as the road environment, reducing the cognitive and visual switching time while maintaining alertness to both the road and dangerous objects
2Loss of information
If warning information is displayed on the windshield for the first time when dangerous object is detected, then the information is provided to the driver, but the driver may overlook the newly displayed information due to focused attention on the direction of vehicle movement
Solution Approach 1:
The patent employs color changes in the displayed warning information to attract the driver's attention. By using distinct colors for different types of warnings or for highlighting the dangerous object, the system creates visual contrast that cuts through the driver's existing focus on the road, ensuring the newly displayed information is noticed and processed reliably
Solution Approach 2:
The patent implements periodic flashing or pulsing of the warning information on the windshield. This periodic action creates a temporal pattern that is difficult for the driver to overlook, as the changing visual stimulus naturally draws attention. The flashing continues or intensifies until the driver acknowledges the hazard, ensuring information perception reliability
3Ease of operation
If the driver focuses on the direction of movement of the vehicle, then the driver maintains situational awareness for operation, but the driver may overlook newly displayed warning information on the windshield
Solution Approach 1:
The patent merges the warning information display with the driver's existing field of view by projecting onto the windshield. Instead of creating a separate information channel that requires attention switching, the system combines hazard warnings with the road view, allowing the driver to maintain operational awareness while simultaneously perceiving warnings in the same visual space

AI summary
An information presenting method and apparatus for a vehicle which may process display information based on a predicted direction of movement of the vehicle, detect an object near the vehicle, determine whether the object is a dangerous object, and control a presentation direction so that the display information is a direction of movement of the vehicle during operation, and if the object is a dangerous object, the information presenting method or apparatus moves the presentation direction from the direction of movement of the vehicle to a direction of the object and presents the display information of areas outside the vehicle.
