Vehicle Transport Priority Control at Route Convergence Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In manufacturing and shipping processes, there is a challenge in determining the priority of which vehicle should be transported first when multiple vehicles converge on different routes, leading to potential collisions and increased transport time.
Innovation Solution
An automatic driving system that includes a priority acquisition unit to set shipment priorities for vehicles and a control instruction unit to determine control content, ensuring higher-priority vehicles are transported preferentially, using cameras for position detection and communication units for remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple vehicles are transported using different routes simultaneously, then transport efficiency is improved, but collision risk increases at route convergence points
Solution Approach 1:
The system performs preliminary determination of passage priority before vehicles reach convergence points. The control instruction unit establishes a predetermined order of passage based on shipment priority, ensuring that higher-priority vehicles are instructed to proceed first, thereby preventing collisions before they occur
Solution Approach 2:
The server acts as an intermediary that coordinates between multiple vehicles and routes. It receives shipment priority information, determines passage priority, and issues control instructions to individual vehicles, mediating the interaction between concurrent vehicle movements to eliminate collision risk
2Device complexity
If vehicles are transported without priority management, then system complexity is reduced, but transport time increases due to collisions and waiting
Solution Approach 1:
The system changes the parameter of vehicle control by introducing shipment priority as a new attribute. Vehicles are assigned different priority levels (first priority, second priority, etc.), and control instructions are adjusted based on these priority parameters, enabling efficient time management without requiring complex vehicle-to-vehicle negotiation protocols
3Loss of time
If shipment priority is assigned to each vehicle, then transport time is reduced through preferential treatment, but information processing complexity increases
Solution Approach 1:
Shipment priority information is acquired in advance before vehicle transport begins. The control instruction unit uses this pre-acquired priority information to determine passage priority and issue control instructions, eliminating the need for real-time priority calculations and reducing information processing complexity during actual transport
Solution Approach 2:
Each vehicle's driving control unit uses the received control instructions (which include priority-based passage information) to autonomously determine its own driving behavior. The vehicle self-adjusts its movement based on the predetermined passage priority, reducing the need for continuous centralized control and simplifying information processing

AI summary
An automatic driving system allows a vehicle with a higher shipment priority to be transported preferentially, by controlling transport of each of several vehicles in any of steps from production to shipment includes: a priority acquisition unit configured to acquire a shipment priority set for each vehicle; and a control instruction unit configured to determine control content for at least some of the vehicles using the priority acquired by the priority acquisition unit such that a vehicle of the several vehicles that is given a first priority is transported in preference to another vehicle of the several vehicles that is given a second priority lower than the first priority, and to instruct the at least some of several vehicles on the control content. Each vehicle includes a driving control unit configured to execute driving control according to instructions from the control instruction unit.
