AR Safety Trajectory Display for Vehicle Hazard Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems lack an efficient method to display critical information to drivers about potential dangers from the vehicle's own systems or other vehicles, especially in fault conditions, which can lead to unsafe driving situations and accidents.
Innovation Solution
A method utilizing a detection unit to assess the surrounding area and vehicle states, generating a safety trajectory that is displayed on a display unit using augmented reality, providing the driver with visual instructions to navigate safely and avoid hazards, including displaying a safety trajectory and potential stopping points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional display methods are used to show hazard information to drivers, then the information can be transmitted, but the driver's reaction time is delayed and understanding is insufficient
Solution Approach 1:
The patent transitions from traditional 2D flat displays to 3D spatial visualization by projecting hazard information and safety trajectories directly onto the windshield in the driver's field of view. This dimensional change allows drivers to perceive hazard locations, distances, and movement paths more intuitively, reducing reaction time and improving safety decisions.
Solution Approach 2:
The system introduces an augmented reality display system as an intermediary between the hazard detection sensors and the driver. This intermediary processes raw sensor data into visualized hazard representations, safety trajectories, and distance indicators that are directly overlaid on the driver's view, enhancing comprehension and response time.
2Reliability
If comprehensive hazard information is provided to the driver, then the driver can make better decisions, but the information processing complexity increases
Solution Approach 1:
The hazard information is segmented into distinct visual elements: hazard icons indicating type and location, safety trajectory lines showing recommended paths, distance indicators, and priority levels. This segmentation allows the complex information to be processed and displayed in manageable, intuitively understood components rather than overwhelming the driver with raw data.
Solution Approach 2:
The patent replaces complex mechanical or manual information processing with automated sensor systems and algorithmic hazard assessment. Detection units continuously monitor the environment, and processing units automatically calculate safety trajectories and hazard priorities, substituting manual driver analysis with automated computational systems that reduce overall system complexity while improving reliability.
