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 the system or vehicles.
Innovation Solution
A system and method for managing a driving negotiation message for a minimal risk maneuver, which includes an input interface device, memory for generating and transmitting a driving negotiation message, and a processor that considers minimal risk maneuver modes to generate messages for collision warning, path change requests, acceleration, deceleration, and lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If autonomous driving systems rely solely on sensor-based detection 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 vehicles and surrounding vehicles. Instead of relying solely on sensor detection, the system uses communication messages to directly obtain driving intention information from other vehicles, thereby improving reliability without significantly increasing system complexity
Solution Approach 2:
The patent segments the information acquisition process into two independent channels: sensor-based detection and V2X communication. This segmentation allows the system to use the appropriate channel based on the specific situation, improving overall reliability while maintaining manageable system complexity through modular architecture
2Reliability
If the autonomous driving system performs comprehensive safety checks and negotiations with all surrounding vehicles during emergency situations, then the reliability of safety assurance is improved, but the response time deteriorates
Solution Approach 1:
The patent implements preliminary action by establishing V2X communication connections and sharing basic vehicle state information during normal operation, before emergency situations occur. When emergencies arise, the system already has pre-established communication channels and partial information, enabling faster response while maintaining comprehensive safety checks
Solution Approach 2:
The patent applies dynamics by adaptively adjusting the scope and intensity of safety negotiations based on the emergency situation. The system dynamically determines which surrounding vehicles require negotiation and what level of detail is needed, rather than performing fixed comprehensive checks with all vehicles, thus reducing response time while maintaining adequate safety assurance
