Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic control systems struggle to effectively manage emergencies and disasters in mixed traffic flows involving autonomous and non-autonomous vehicles, and they lack the ability to confirm the reliability of information received from on-site surveillance equipment.
Innovation Solution
A reliability check system and method that includes a sensor unit for detecting emergency situations, an emergency determination unit for analyzing sensor data, a data checking unit for verifying the integrity and authenticity of the data, and a controller for classifying the reliability of the information and transmitting it to autonomous vehicles and infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traffic control system uses on-site surveillance equipment to detect emergency situations, then the system can provide real-time emergency information, but the reliability of the received information cannot be confirmed due to potential hacking and data distortion
Solution Approach 1:
The patent implements a feedback mechanism where the autonomous vehicle sends back acknowledgment and status information to the infrastructure, and the infrastructure sends verification responses to confirm data integrity. This bidirectional feedback loop allows the system to detect and respond to hacking attempts or data distortion in real-time, ensuring the reliability of emergency detection information before it is used for autonomous driving decisions.
Solution Approach 2:
The patent introduces a communication protocol with verification mechanisms as an intermediary layer between the on-site surveillance equipment and the autonomous vehicle. This intermediary includes authentication tokens, encryption layers, and verification steps that mediate the data transmission, preventing direct hacking or data distortion while maintaining real-time emergency information flow.
2Speed
If the system transmits emergency information directly from on-site sensors to autonomous vehicles, then the response time is fast, but the system cannot detect or prevent information tampering
Solution Approach 1:
The patent applies preliminary action by performing authentication, encryption, and integrity verification of emergency information before it is transmitted from on-site sensors to autonomous vehicles. The system pre-establishes communication protocols, authentication tokens, and verification checklists that are executed automatically before data transmission, ensuring both fast response time and information authenticity without adding significant delay.
3Adaptability or versatility
If the existing traffic control system manages mixed traffic flow, then it can handle both autonomous and non-autonomous vehicles, but it cannot effectively respond to emergencies caused by autonomous vehicles
Solution Approach 1:
The patent applies local quality by tailoring the emergency response protocol specifically for autonomous vehicles within the mixed traffic flow. The system identifies autonomous vehicles through their communication capabilities and applies enhanced verification and response mechanisms only to those vehicles, while maintaining standard protocols for conventional vehicles. This localized approach enables effective emergency response for autonomous vehicles without overcomplicating the entire mixed traffic management system.

AI summary
A reliability check system for unexpected situation detection information in a mixed traffic flow of a mix of autonomous and non-autonomous vehicles includes a sensor unit configured to detect emergency and disaster situations on or around a road, including at least one of a camera, a lidar, and a radar, an emergency determination unit configured to analyze information received from the sensor unit to determine an emergency type, a controller configured to classify a set grade according to detection information from the emergency determination unit and transmit a response manual to an autonomous vehicle and an on-site terminal, and a data checking unit configured to verify at least one of whether firmware of the information received from the emergency determination unit has been falsified, whether a vehicle is hacked by remote control, whether CAN tampering occurred, and whether communication channel tampering occurred, and transmit verified data to the controller.
