Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving systems face challenges in ensuring minimal safety during emergency situations due to limitations in identifying surrounding vehicles' driving intentions and potential failures in sensors or system operations.
Innovation Solution
A system and method for managing a driving negotiation target for minimal risk maneuvers (MRMs) using V2X communication, which involves receiving surrounding vehicle information and high precision map data to select a driving negotiation target and generate appropriate messages for safe maneuvering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If autonomous driving systems rely solely on sensor-based autonomous driving to identify surrounding vehicles, then the system complexity is reduced, but the reliability of identifying driving intentions deteriorates
Solution Approach 1:
The patent introduces V2X communication as an intermediary mechanism between autonomous driving systems. Instead of relying solely on sensors to detect and interpret driving intentions, the system uses V2X communication to directly exchange driving intention data with surrounding vehicles. This mediator approach resolves the contradiction by providing reliable driving intention information without increasing sensor system complexity.
Solution Approach 2:
The patent segments the information acquisition process into two independent channels: sensor-based detection and V2X communication-based information exchange. By separating these functions, the system can maintain simple sensor architecture while obtaining reliable driving intention data through V2X, thus resolving the contradiction between system complexity and reliability.
2Speed
If autonomous driving systems do not perform driving negotiations with surrounding vehicles, then the response time in emergency situations is reduced, but the safety in emergency situations deteriorates
Solution Approach 1:
The patent implements preliminary driving negotiations between the ego vehicle and surrounding vehicles before emergency situations occur. By pre-establishing communication channels and negotiating driving intentions in advance, the system prepares for potential emergencies without delaying the actual response. This allows rapid execution of minimal risk maneuvers while maintaining safety through pre-coordinated actions with surrounding vehicles.
3Ease of operation
If the autonomous driving system performs minimal risk maneuvers without selecting specific negotiation targets, then the maneuver execution is simplified, but the effectiveness of risk mitigation deteriorates
Solution Approach 1:
The patent applies local quality by selectively identifying specific surrounding vehicles as negotiation targets based on their spatial relationship and relevance to the minimal risk maneuver. Instead of treating all surrounding vehicles uniformly, the system focuses communication resources on vehicles that are most critical to the current maneuver, thereby maintaining simple execution while improving risk mitigation effectiveness through targeted negotiations.

AI summary
Disclosed are a system and method for managing a driving negotiation target for a minimal risk maneuver. The system includes an input interface device configured to receive surrounding vehicle information from surrounding vehicles of an ego vehicle through V2X communication and to receive map information from a high precision map management unit, memory in which a program that selects a driving negotiation target based on the surrounding vehicle information and the map information has been stored, and a processor configured to execute the program. The processor selects the driving negotiation target, among the surrounding vehicles, by considering a minimal risk maneuver mode.
