AGV Travel Priority Control for Single Guide Path Passing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated guided vehicles (AGVs) traveling along a single guide path face challenges in efficiently passing each other, as only one vehicle can proceed while the other must divert, leading to potential bottlenecks and inefficiencies in transportation.
Innovation Solution
A vehicle control system that determines travel priorities based on conditions such as load presence, size, weight, and direction, allowing vehicles to dynamically adjust their routes to ensure efficient passage by comparing priorities and directing one vehicle to continue on the main path while the other takes a side route.

1Area of stationary object
If multiple AGVs share a single guide path, then space utilization is improved, but traffic bottlenecks occur when vehicles need to pass each other
Solution Approach 1:
The system dynamically determines travel priorities based on real-time conditions such as load presence, vehicle size, and direction of travel. This dynamic priority assignment allows the control system to adaptively manage traffic flow, deciding which vehicle should proceed first when conflicts arise, thereby maintaining high transportation efficiency while utilizing a single guide path.
Solution Approach 2:
The control system receives information from multiple AGVs about their current conditions (load status, size, direction) and uses this feedback to determine travel priorities. This feedback mechanism enables the system to make informed decisions about which vehicle should have right of way, preventing bottlenecks and ensuring continuous efficient operation of the shared guide path.
2Reliability
If one vehicle must divert to a side route to allow passing, then collision is avoided, but transportation time increases
Solution Approach 1:
The control system determines travel priorities in advance before conflicts occur. By pre-establishing which vehicle should proceed first based on their conditions, the system prevents bottlenecks from forming in the first place, reducing the need for vehicles to divert to side routes and minimizing transportation time delays.
3Area of stationary object
If a single guide path is used, then space requirements are reduced, but the system becomes more complex in managing vehicle interactions
Solution Approach 1:
The system uses parameter changes in travel priority determination based on vehicle conditions (load presence, size, direction). By changing the priority parameter dynamically according to these conditions, the control system manages vehicle interactions on a single guide path without requiring complex physical infrastructure or multiple paths.

AI summary
A vehicle control system determines a travel priority of a vehicle based on a travel condition of the vehicle. In response to detection of an oncoming vehicle ahead of the vehicle along a single guide path, the system compares between the travel priority of the vehicle, and a travel priority of the oncoming vehicle, and selects one of the vehicle and the oncoming vehicle as a vehicle to change a traveling route, to allow the unselected vehicle to continue traveling along the single guide path.
