Autonomous Driving Path Control in Narrow Shared Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving devices often encounter obstacles and collisions when multiple devices share the same driving paths, particularly in narrow passages, due to overlapping or crossing paths, which can lead to unsafe operations and service disruptions.
Innovation Solution
A control device and method that determine and manage driving paths for autonomous driving devices by exchanging information and using cross-driving rules to adjust paths, sensor margins, and speeds, and can communicate with external control servers and facility devices to ensure safe passage and route optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple autonomous driving devices share the same driving paths, then service coverage and operational efficiency are improved, but collision risk and operational safety deteriorate due to overlapping paths in narrow passages
Solution Approach 1:
The patent introduces a control device as an intermediary that manages multiple autonomous driving devices. This control device receives driving path requests, determines collision-free paths by considering other devices' positions, and provides optimized routing instructions. This mediator resolves the contradiction by enabling multiple devices to operate safely in shared spaces through centralized coordination.
Solution Approach 2:
The system implements feedback mechanisms where autonomous driving devices report their positions and driving states to the control device, which then adjusts path recommendations in real-time. This continuous feedback loop allows the system to maintain high productivity while ensuring safety by dynamically responding to changing conditions and preventing collisions.
2Device complexity
If autonomous driving devices use fixed driving paths, then route planning simplicity is improved, but adaptability to dynamic obstacles and changing environments deteriorates
Solution Approach 1:
The patent implements dynamic path planning where the control device continuously updates driving paths based on real-time environmental data and device positions. Rather than fixed routes, the system generates adaptive paths that respond to obstacles, passage width changes, and other dynamic conditions, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The system performs preliminary path planning by the control device before autonomous driving devices begin movement, anticipating potential conflicts and pre-determining collision-free routes. This advance planning maintains simplicity while incorporating adaptability by considering dynamic factors beforehand and providing optimized paths that prevent future conflicts.

AI summary
A control device and a method for controlling an autonomous driving device thereof are provided. The control device includes a communication device, a processor, and storage. The processor receives a driving path request from a first external autonomous driving device, receives information associated with a second external autonomous driving device and information associated with a passage, determines a driving path of the first external autonomous driving device and a driving path of the second external autonomous driving device, provides the first external autonomous driving device and the second external autonomous driving device with the determined driving paths, transmits a control request for allowing the second external autonomous driving device to drive along the determined driving path to an external control device, receives a response to the control request, and provides the first external autonomous driving device with the determined driving path or a corrected driving path.
