Solution Overview
Problem
Ensuring safety and efficiency for work vehicles to automatically run between multiple areas while preventing accidents and reducing running efficiency issues on connection routes.
Innovation Solution
A setting method that establishes an inter-area route and automatic run permission area, allowing work vehicles to automatically run on connection routes connecting multiple work areas, with safety measures in place to prevent collisions and optimize route efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple work vehicles are allowed to automatically run on the connection route between fields, then running efficiency is improved, but safety is compromised due to difficulty in preventing collisions and accidents
Solution Approach 1:
The connection route is divided into multiple automatic run permission areas along its length. Each area can independently permit or restrict automatic running, allowing the system to manage multiple work vehicles by spatial segmentation rather than temporal scheduling, thus maintaining high productivity while ensuring safety through localized control zones
Solution Approach 2:
The automatic run permission area acts as an intermediary control mechanism between the work vehicles and the connection route. This intermediary layer manages vehicle access and movement permissions, enabling efficient multi-vehicle operation while maintaining safety through structured permission management
2Reliability
If the work vehicle transiently stops and waits at field entrance/exit to ensure safety, then safety is improved, but running efficiency deteriorates due to waiting time
Solution Approach 1:
The automatic run permission area is established in advance along the connection route, pre-defining safe zones for automatic running. This preliminary setup eliminates the need for transient stopping at field entrances/exits, as vehicles can continuously navigate through pre-approved permission areas, thereby maintaining both safety and running efficiency

AI summary
[Problem] Provide a setting method, an automatic run method, a setting system, and a setting program which are capable of causing a work vehicle to automatically run between plural areas with safety and a good efficiency. [Solution] A setting process unit 211 sets an inter-area route that causes a work vehicle 10 to automatically run on a road R0 that connects a plurality of fields, and sets, as an automatic run permission area AR1 that permits the automatic run of the work vehicle 10, a given range including the plurality of fields and the road R0 which is for entering each of the plurality of fields.
