Innovation Solution
An autonomous driving safety control system based on edge infrastructure that detects fallback situations and executes safety processes, including emergency stops and passenger location sharing, to prioritize passenger safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving system focuses on vehicle control during fallback situations, then vehicle control capability is improved, but passenger safety is insufficient
Solution Approach 1:
The patent introduces an edge infrastructure as an intermediary between the autonomous driving system and the external environment. This intermediary provides additional information (safety zone locations, environmental data) and communication capabilities that enable the system to address passenger safety concerns while maintaining vehicle control capability during fallback situations
Solution Approach 2:
The patent adds a new dimension of operation by implementing multiple fallback scenarios beyond basic vehicle control. These include scenarios for passenger evacuation, communication with external systems, and environmental awareness, thereby expanding the system's capability space to address comprehensive passenger safety
2Reliability
If the system implements multiple safety scenarios for fallback situations, then passenger safety is improved, but system complexity increases
Solution Approach 1:
The patent segments the fallback response into distinct scenarios (e.g., safe stop scenarios, passenger evacuation scenarios, communication scenarios). Each scenario is handled by specific functional modules, which reduces the complexity of managing all safety functions monolithically while maintaining comprehensive passenger safety coverage
3Reliability
If the system shares passenger location information through edge infrastructure, then passenger safety is improved, but information security risks increase
Solution Approach 1:
The patent establishes predetermined protocols and procedures for information sharing before actual fallback situations occur. These pre-defined frameworks include criteria for when to share information, what information to share, and with whom, thereby enabling effective passenger safety monitoring while managing information security risks through advance planning

AI summary
An autonomous driving safety control system based on edge infrastructure includes an autonomous driving system (100) controlling autonomous driving, an error detection unit (200) detecting a fallback situation, and a safety controller (300) driving a safety process for each fallback situation by interworking with an edge infrastructure when a fallback situation occurs, wherein the safety controller (300) transmits a fallback situation and location information of a passenger through the edge infrastructure.
