Secure AR Driver Assistance for Non-Autonomous Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively inform non-autonomous vehicles of road conditions and signage in autonomous vehicle environments, lacking secure communication protocols and leading to potential safety risks due to the presence of both autonomous and human-operated vehicles on the roadways.
Innovation Solution
The implementation of a secure communication protocol, such as DICE-RIoT, enables non-autonomous vehicles to receive and display real-time environmental indicators like traffic lights, speed limits, and construction notices through augmented reality or heads-up displays, ensuring secure and accurate visualization of road conditions, independent of language barriers, using secure connections with roadways and validation of indicator packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual indicators (road signs, traffic lights) are kept for non-autonomous vehicles, then human-operated vehicles can navigate safely, but autonomous vehicles cannot access digital road condition data for processing
Solution Approach 1:
The patent introduces smart roadways and markers as intermediary devices that transmit road condition information digitally to autonomous vehicles. These intermediaries bridge the gap between physical road infrastructure and autonomous vehicle sensors, enabling data exchange without requiring autonomous vehicles to interpret visual signs directly.
Solution Approach 2:
The patent replaces the mechanical/visual information transmission system (physical road signs) with an electronic/digital communication system. Smart roadways use electronic signals, RFID tags, or other digital communication methods to transmit road condition data directly to autonomous vehicles, substituting the need for visual indicators.
2Reliability
If smart roadway systems are implemented to communicate with autonomous vehicles, then road condition data is transmitted digitally, but security vulnerabilities (man-in-the-middle attacks) are introduced
Solution Approach 1:
The patent implements preliminary security measures including authentication protocols and encryption before data transmission occurs. The system establishes trusted communication channels in advance, verifying the identities of autonomous vehicles and smart roadway components to prevent unauthorized access and man-in-the-middle attacks.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors communication integrity and authentication status. When security threats or anomalies are detected, the system can terminate connections, alert authorities, or switch to backup communication channels, creating a closed-loop security system.
3Adaptability or versatility
If visual indicators are removed from roadways, then autonomous vehicle environment becomes optimized, but non-autonomous vehicles lose access to road condition information
Solution Approach 1:
The patent creates a universal communication system that serves both autonomous and non-autonomous vehicles. Smart roadways transmit information digitally to autonomous vehicles while maintaining compatibility with existing visual infrastructure for human-operated vehicles. The system can adapt its output format based on the recipient vehicle's capabilities.
Solution Approach 2:
The patent adds a digital communication dimension to the traditional visual road signage system. Instead of relying solely on visual indicators in the physical dimension, the system introduces electromagnetic/digital communication channels, creating a multi-dimensional information transmission architecture that serves different vehicle types simultaneously.
