AR Blind Reveal Warning for Hidden Vehicle Collision Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems do not provide warnings for 'blind reveal' situations, where a host vehicle may collide with a second remote vehicle that is hidden due to the first remote vehicle switching lanes, lacking real-time vehicle positioning data to predict and prevent such collisions.
Innovation Solution
A system and method using V2V communication to detect approaching vehicles and determine the probability of a blind reveal, transmitting a command signal to a multi-focal plane augmented reality display to show a warning alert if the probability exceeds a threshold, with the alert's size, type, and location optimized based on the vehicle user's gaze and the scenario.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional display system is used, then the device complexity is low, but the driver cannot receive timely warnings for blind reveal situations
Solution Approach 1:
The display information is segmented into multiple focal planes: a first image plane showing the real-world view and a second image plane displaying virtual warning images. This segmentation allows the system to overlay safety warnings without blocking the driver's view of the road, thereby improving collision prevention while maintaining system simplicity.
Solution Approach 2:
A multi-focal plane augmented reality display acts as an intermediary between the vehicle's sensor data and the driver. It processes blind reveal detection data and presents it in an optimized visual format that enhances driver awareness without requiring complex additional hardware or changing the fundamental display system architecture.
2Reliability
If warning information is always displayed, then the driver receives comprehensive safety information, but the driver's attention is diverted from the road
Solution Approach 1:
The warning images are displayed with specific visual characteristics (brightness, size, type) tailored to the particular blind reveal scenario. The display adapts the local quality of the warning based on the probability of blind reveal and environmental conditions, ensuring effective communication without unnecessary distraction.
Solution Approach 2:
The display dynamically adjusts the characteristics of warning images based on real-time conditions including the probability of blind reveal, ambient light levels, and driver gaze direction. This dynamic adaptation ensures warnings are visible and effective only when needed, maintaining driver attention on the road.
3Reliability
If the warning image characteristics are standardized, then the display system is simple to implement, but the warning effectiveness varies in different driving scenarios
Solution Approach 1:
The system changes multiple parameters of the warning images including brightness, size, type, and location based on the detected driving scenario and blind reveal probability. These parameter adjustments are made automatically by the controller, providing scenario-adaptive warnings without requiring complex manual configuration or additional hardware.

AI summary
A method for providing a blind reveal warning on multi-focal plane augmented reality display includes receiving remote-vehicle data, which includes information about a plurality of remote vehicles. The remote vehicles include a first remote vehicle located directly in front of the host vehicle and a second remote vehicle in front of the first remote vehicle. The method further includes determining an approach rate of the first remote vehicle to the second remote vehicle. The method further includes determining a probability that the first remote vehicle will perform a blind reveal and comparing that probability with a predetermined threshold value. The method further includes, in response to determining that the probability that the first remote vehicle will perform the blind reveal is greater than the predetermined threshold value, transmitting a command signal to the display of the host vehicle to display a virtual image.
