ADS Emergency Information Control Using UE Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for autonomous vehicles lack efficient and safe methods for handling emergency situations by transmitting and receiving data among an automated driving system (ADS), user equipment (UE), and infrastructure, particularly at higher autonomous driving levels.
Innovation Solution
An emergency situation control method and device that enables efficient data transmission and processing between ADS and UE, allowing for safe autonomous driving by periodically or aperiodically receiving status information, identifying emergency situations, and controlling emergency responses based on UE responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ADS transmits emergency information to the UE, then the UE can be aware of the emergency situation, but redundant transmission occurs when the UE has already received the information from other sources
Solution Approach 1:
The UE feeds back status information to the ADS indicating whether it has received emergency information from other sources. The ADS uses this feedback to determine whether to transmit emergency information, avoiding redundant transmission and energy waste while maintaining reliable emergency situation handling.
2Reliability
If the ADS transmits emergency information to the UE, then the UE can respond to the emergency situation, but the UE may not respond in critical situations
Solution Approach 1:
The ADS transmits emergency information to the UE in advance before the critical situation fully develops. This preliminary action ensures the UE has the information needed to respond promptly when the situation becomes critical, reducing response time while maintaining reliability.
3Measurement precision
If the ADS continuously monitors UE status, then the ADS can identify emergency situations accurately, but the system complexity increases
Solution Approach 1:
The UE autonomously monitors its own status regarding emergency information reception and actively reports this status to the ADS. This self-service approach enables accurate emergency situation detection without requiring complex continuous monitoring infrastructure, thereby reducing system complexity while maintaining measurement precision.

AI summary
An emergency situation control method for transmitting and receiving information between an automated driving system (ADS) and a user equipment (UE), an automated driving system (ADS) for transmitting and receiving information to and from a user equipment (UE), and a vehicle therefor, are provided. The method includes periodically or aperiodically receiving status information from the UE by the ADS, the status information including information indicating that the UE has received emergency information, identifying, by the ADS, an emergency situation based on the status information, determining, by the ADS, whether or not to transmit the emergency information to the UE, and controlling, by the ADS, an emergency situation related to the emergency information.
