Autonomous Vehicle Emergency Triggers With Authenticated Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack effective methods to respond to emergency vehicles, relying heavily on visual and audible perception which can result in false positives and failures, posing safety risks and potential malicious takeovers.
Innovation Solution
Implementing a system that uses external triggers, including direct communication links and redundant communication pathways, to enable autonomous vehicles to respond to emergency vehicles, ensuring authentication and permission from trusted sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicles use visual and audible perception to detect emergency vehicles, then they can identify emergency vehicles, but false positives and detection failures occur reducing reliability
Solution Approach 1:
The patent introduces an intermediary communication system between emergency vehicles and autonomous vehicles. Emergency vehicles transmit authenticated signals through designated communication channels, serving as a mediator that eliminates the need for autonomous vehicles to visually or auditorily detect emergency vehicles. This intermediary mechanism resolves the contradiction by providing reliable detection without the false positives inherent in sensor-based perception.
Solution Approach 2:
The patent replaces the mechanical sensor-based detection system (cameras, microphones, lidar) with an electronic communication-based system. Instead of using visual and audible perception to detect emergency vehicles, the system uses authenticated electronic signals transmitted from emergency vehicles. This substitution eliminates detection failures and false positives associated with sensor systems while maintaining reliable emergency vehicle identification.
2Adaptability or versatility
If autonomous vehicles accept external communication signals, then they can respond to emergency vehicles, but malicious takeovers may occur
Solution Approach 1:
The patent implements preliminary authentication actions before the autonomous vehicle responds to emergency vehicle signals. The system pre-establishes trusted communication channels and validates signal authenticity before executing any response commands. This preliminary verification prevents malicious takeovers while maintaining the ability to respond to legitimate emergency vehicles, resolving the contradiction between adaptability and security.
Solution Approach 2:
The patent incorporates feedback mechanisms where the autonomous vehicle verifies incoming signals against authenticated emergency vehicle identifiers and communication protocols. The system continuously monitors communication integrity and only responds when verification confirms the signal originates from a legitimate emergency vehicle. This feedback loop enables responsive capability while preventing malicious control through continuous validation.
