XR Slot Reservation for Vehicle Intersection Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roadway intersections pose a high risk for collisions due to complex and unpredictable traffic situations, with existing solutions lacking effective methods to guide vehicles safely through these areas using Cross Reality (XR) technologies.
Innovation Solution
An XR system installed in an electronic control unit of a vehicle that utilizes Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) to analyze Vehicle-to-Everything (V2X) wireless messages, determining a safe zone and reserved slot for the vehicle to avoid collisions by providing a graphical overlay on a Heads-Up Display (HUD) and controlling the Advanced Driver Assistance System (ADAS) to maintain the vehicle within this safe zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional driving without XR assistance is used, then the driver focuses on the road, but the driver lacks clear guidance on safe positioning at intersections increasing collision risk
Solution Approach 1:
The XR system acts as an intermediary between the driver and the complex intersection environment. It receives V2X data about remote vehicles and traffic conditions, processes this information to determine safe zones and reserved slots, and presents this guidance through graphical overlays on the HUD. This intermediary function provides the driver with clear safe positioning guidance without requiring direct interpretation of complex traffic data.
Solution Approach 2:
The patent replaces traditional mechanical navigation cues with XR-based visual information. Instead of relying solely on physical road markings and conventional mirrors, the system uses graphical overlays projected through the windshield to display safe zones and reserved slots, substituting a more advanced information presentation mechanism for traditional mechanical guidance systems.
2Reliability
If the driver is provided with detailed intersection guidance information, then collision risk is reduced, but the complexity of the navigation system increases
Solution Approach 1:
The XR system integrates multiple functions into a single unified platform. It simultaneously performs V2X data reception, traffic situation analysis, safe zone calculation, reserved slot determination, and graphical overlay presentation all through one system. This multi-functionality reduces overall system complexity compared to having separate systems for each function while maintaining comprehensive collision avoidance capabilities.
Solution Approach 2:
The system automatically determines safe zones and reserved slots by analyzing V2X data from remote vehicles without requiring manual input from the driver. The XR system self-calculates positioning guidance based on real-time traffic conditions, reducing the need for complex manual control mechanisms while maintaining high collision avoidance reliability.
3Measurement precision
If the vehicle uses V2X communication and XR display to determine safe zones, then positioning accuracy is improved, but the energy consumption increases
Solution Approach 1:
The system performs preliminary calculations of safe zones and reserved slots before the vehicle reaches critical intersection positions. By analyzing V2X data in advance and pre-determining positioning guidance, the system reduces the need for continuous high-computation processing at critical moments, thereby maintaining positioning accuracy while managing energy consumption more efficiently.
