Mobile Body Priority Control for Automated Driving Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple vehicles engaged in automated driving experience a failure, it is unclear how to prioritize and handle the stopped vehicles effectively.
Innovation Solution
A control device and method that specify a target mobile body to be preferentially handled based on its state, such as proximity to downstream or upstream processes, expected shipping time, or presence of obstacles, and perform necessary measures to resume automated driving or manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple mobile bodies are stopped due to abnormal states, then safety is ensured, but productivity decreases and idle time increases in downstream processes
Solution Approach 1:
The control device performs preliminary actions by specifying priority orders for handling mobile bodies before they cause downstream process idle time. The system determines priority based on pre-set criteria (distance to downstream process, shipping deadline, etc.) and establishes a handling sequence in advance, allowing for more efficient resumption of operations while maintaining safety protocols
2Reliability
If multiple mobile bodies are stopped due to abnormal states, then safety is ensured, but loss of time occurs in downstream processes
Solution Approach 1:
The control device performs preliminary actions by specifying priority orders for handling mobile bodies before they cause downstream process idle time. The system determines priority based on pre-set criteria (distance to downstream process, shipping deadline, etc.) and establishes a handling sequence in advance, allowing for more efficient resumption of operations while maintaining safety protocols
Solution Approach 2:
The control device uses feedback from the abnormal state detection to dynamically adjust handling priorities. By continuously monitoring mobile body states, positions, and downstream process requirements, the system provides feedback that informs the priority specification, enabling optimized time management while ensuring safety through controlled resumption of operations
3Ease of operation
If mobile bodies are handled without priority specification, then operational simplicity is maintained, but shipping delays occur
Solution Approach 1:
The control device performs preliminary actions by specifying priority orders for handling mobile bodies before they cause downstream process idle time. The system determines priority based on pre-set criteria (distance to downstream process, shipping deadline, etc.) and establishes a handling sequence in advance, allowing for more efficient resumption of operations while maintaining safety protocols
Solution Approach 2:
The control device changes operational parameters by introducing priority levels based on multiple factors (distance to downstream process, shipping deadline, model type, indoor/outdoor location). This parameter-based priority system transforms the operational approach from simple first-come-first-served to an optimized sequence that reduces shipping delays while maintaining ease of operation through automated decision-making

AI summary
A control device (120) includes a processor (11). The processor (11) is configured to: specify, in a case where an abnormal state occurs in a plurality of mobile bodies (20) being performing automated driving autonomously or through remote control, at least one mobile body (20) to be preferentially handled as a target mobile body, from among the plurality of mobile bodies (20), based on a state of the plurality of mobile bodies (20); and perform control of taking necessary measures on the target mobile body.
