Tele-Operated Vehicle Deadlock Resolution Using Shared Reference Locations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tele-operated driving systems face inefficiencies in communication and resource usage when dealing with deadlock situations in autonomous vehicles, as each vehicle requires redundant information and time to understand the situation, leading to increased data traffic and solving time.
Innovation Solution
The method involves detecting deadlock situations, determining a reference location, and reporting it with a timestamp to a control center, enabling the reuse of information for subsequent vehicles, thereby reducing total deadlock solving time and resource consumption through tele-operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each autonomous vehicle independently processes deadlock situations through tele-operation, then each vehicle receives dedicated attention and resolution, but communication resources are wasted and solving time increases due to redundant information transmission
Solution Approach 1:
The patent merges multiple deadlock situation reports from different vehicles into a single centralized database at the control center. When the same deadlock situation is detected by multiple vehicles, the control center identifies it as a duplicate based on matching situation descriptors and location data, then provides a single pre-computed resolution instruction to all affected vehicles. This combining approach eliminates redundant communication while ensuring all vehicles receive the same reliable resolution guidance.
Solution Approach 2:
The control center performs preliminary analysis and resolution computation for deadlock situations before they affect multiple vehicles. By maintaining a database of known deadlock patterns and their resolutions, the system prepares resolution instructions in advance. When a vehicle reports a deadlock, the control center checks if a resolution already exists in the database and can immediately provide it without real-time computation delays, improving both speed and resource efficiency.
2Loss of information
If each vehicle reports complete deadlock situation information to the control center, then the control center has full information for resolution, but data traffic increases significantly
Solution Approach 1:
The patent extracts only the essential elements needed for deadlock identification and resolution from the complete vehicle sensor data. Instead of transmitting all raw sensor information, the system extracts key descriptors such as situation type, location coordinates, and critical obstacle positions. This extraction process maintains sufficient information completeness for the control center to understand and resolve the deadlock while dramatically reducing the volume of transmitted data.
Solution Approach 2:
The control center maintains a copied database of known deadlock situations and their resolutions. When a vehicle encounters a similar deadlock, the system copies the relevant resolution instructions from the database rather than computing a new solution from scratch. This copying approach ensures information completeness for resolution while minimizing data traffic by reusing previously computed solutions.
3Ease of operation
If the control center processes each deadlock situation independently for each vehicle, then each vehicle receives customized resolution, but total solving time increases
Solution Approach 1:
The patent implements a universal resolution approach where the control center identifies common deadlock patterns that affect multiple vehicles and computes a single resolution strategy that works for all. The system determines whether a deadlock situation is unique or recurring, and for recurring situations, applies a universal resolution instruction to all affected vehicles simultaneously. This multi-functionality approach maintains ease of operation by providing appropriate customization for unique situations while dramatically reducing solving time for common patterns.
Solution Approach 2:
The control center performs preliminary classification of deadlock situations upon first detection, categorizing them by type, location, and characteristics. This preliminary action creates a structured database that enables rapid matching of future situations to known patterns. When a new deadlock is reported, the system immediately checks against the pre-classified database and can provide pre-computed resolutions without重新启动 the full analysis process, thus reducing total solving time while maintaining resolution effectiveness.
