Mobile Body Priority Control for Automated Driving Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving systems lack a clear method to determine the priority order for handling multiple vehicles that have stopped due to failures, leading to inefficiencies in resuming operations.
Innovation Solution
A control device and method that specify a target mobile body to be preferentially handled based on predefined conditions such as proximity to downstream or upstream processes, shipping deadlines, and environmental factors, allowing for immediate resumption of automated driving and reduced idle times.
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 due to idle time in downstream processes
Solution Approach 1:
The system changes the parameter of handling priority by evaluating multiple conditions (distance to downstream process, distance to upstream process, shipping deadline) and determining the mobile body with the highest priority. This allows dynamic adjustment of which mobile body to handle first, minimizing idle time in downstream processes while maintaining safety.
2Ease of operation
If mobile bodies are handled in arbitrary order, then ease of operation is maintained, but loss of time increases due to idle time in downstream processes
Solution Approach 1:
The system changes the parameter of handling sequence by introducing a priority determination mechanism that evaluates multiple conditions. This automated priority assignment maintains ease of operation (the control device automatically determines the order) while minimizing loss of time by ensuring mobile bodies are handled in an order that prevents downstream process idle time.
3Device complexity
If mobile bodies are handled without priority determination, then device complexity is reduced, but loss of time increases due to stagnation in upstream and downstream processes
Solution Approach 1:
The system changes the parameter of process flow efficiency by introducing a priority determination mechanism that evaluates multiple conditions. This minimizes stagnation time in both upstream and downstream processes by ensuring mobile bodies are handled in an optimal order, while the complexity is managed through automated evaluation rather than manual coordination.
4Ease of operation
If mobile bodies are handled in arbitrary order, then ease of operation is maintained, but shipping deadlines may be missed
Solution Approach 1:
The system changes the parameter of handling priority by including shipping deadline information in the priority determination. Mobile bodies with closer shipping deadlines are assigned higher priority, ensuring that shipping deadlines are met while the control device automatically manages the operation without requiring manual intervention.

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