Solution Overview

Problem

Autonomous vehicles lack a method to effectively respond to external triggers from emergency vehicles, relying heavily on visual and audible perception which can result in false positives and failures to detect emergency vehicles, posing danger to the public and risking fines, while also being designed to limit communication to reduce security risks from malicious actors.

Innovation Solution

The system enables communication between emergency vehicles and autonomous vehicles using external triggers through a network of communication links, including direct communication methods like Bluetooth and modulated light transmission, with redundancies to authenticate and authorize instructions, allowing emergency vehicles to control the autonomous vehicle safely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If autonomous vehicles use visual and audible perception to detect emergency vehicles, then they can identify emergency vehicles, but false positives and failures to detect occur resulting in safety risks and fines

Engineering Contradiction:
Improvedetection accuracyVSAvoidsafety reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent introduces an intermediary communication system between emergency vehicles and autonomous vehicles. Emergency vehicles transmit authenticated signals through communication networks (direct, indirect, or hybrid paths) that serve as reliable mediators, eliminating the need for autonomous vehicles to independently detect and interpret emergency vehicle signals, thereby resolving false positives and detection failures

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where autonomous vehicles receive authenticated communication signals from emergency vehicles, confirm receipt and compliance, and provide status updates. This bidirectional feedback loop ensures reliable detection and response, eliminating the uncertainty and errors associated with unidirectional visual and audible perception

Inventive Principle:
Principle #23Feedback

2Reliability

If autonomous vehicles limit communication to reduce security risks, then security is improved, but the ability to respond to emergency vehicles is reduced

Engineering Contradiction:
Improvesecurity reliabilityVSAvoidemergency response capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by implementing different communication security levels for different scenarios. Normal operations maintain limited communication for security, while emergency situations authenticated through specific protocols (emergency vehicle signal authentication, trusted path verification) enable enhanced communication capabilities. This localized approach to communication quality allows security to be maintained while enabling emergency responsiveness when needed

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The communication system dynamically adjusts its state between restricted normal operation and expanded emergency response modes. The system transitions between these states based on authenticated signals and communication path verification, allowing the autonomous vehicle to adapt its communication capabilities in real-time based on operational context and security requirements

Inventive Principle:
Principle #15Dynamics

3Loss of time

If emergency vehicles communicate directly with autonomous vehicles, then response time is reduced, but security risks from malicious actors increase

Engineering Contradiction:
Improveresponse timeVSAvoidsecurity threats
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The patent implements preliminary authentication actions before direct communication occurs. Emergency vehicles and autonomous vehicles establish trusted communication paths in advance through authentication protocols, verify signal legitimacy, and confirm identity before exchanging operational commands. This preliminary security verification enables direct communication without exposing the system to malicious actors

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes redundant authenticated communication paths and verification mechanisms in advance to cushion against potential security threats. Multiple trusted communication routes (direct, indirect, hybrid) are pre-configured and verified, providing fallback options if one path is compromised, thereby enabling rapid response while maintaining security through layered protection

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
