Agricultural Machine Travel Control for Remote Boundary Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines equipped with remote manipulation systems often lack effective mechanisms to prevent unintended travel into forbidden areas, leading to potential accidents or inefficiencies in task execution.
Innovation Solution
A travel control system that includes a storage for permitted and forbidden areas and a controller capable of disabling remote manipulation when the agricultural machine attempts to enter forbidden areas, ensuring it remains within designated safe zones for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote manipulation is enabled for agricultural machines, then operational flexibility and task execution capability are improved, but the risk of unintended travel into forbidden areas increases
Solution Approach 1:
The system pre-defines permitted and forbidden areas before remote manipulation operations begin. The controller stores position information of these areas and uses them to prevent unintended travel during remote manipulation, addressing safety concerns before they occur.
Solution Approach 2:
The controller acts as an intermediary between the remote manipulation input and the agricultural machine's travel control. It receives position information, determines whether the machine is in permitted or forbidden areas, and selectively enables or disables remote manipulation based on this determination.
2Productivity
If the agricultural machine operates in autonomous self-traveling mode, then operational efficiency is improved, but the ability to perform remotely-manipulated tasks is reduced
Solution Approach 1:
The system dynamically switches between self-traveling mode and remote manipulation mode based on operational requirements. The controller can transition between these modes and selectively enable remote manipulation within permitted areas, allowing the machine to adapt to different task requirements.
3Reliability
If remote manipulation is completely disabled in forbidden areas, then safety is improved, but operational versatility is reduced
Solution Approach 1:
The system applies different control qualities to different spatial locations. Remote manipulation is completely disabled in forbidden areas for safety, while permitted areas allow selective remote manipulation. This local differentiation maintains safety while preserving operational versatility where appropriate.

AI summary
A travel control system for an agricultural machine capable of performing remotely-manipulated traveling includes a storage to store the position of a permitted area in which the remotely-manipulated traveling is permitted and a position of a forbidden area in which the remotely-manipulated traveling is forbidden, and a controller operable in a self-traveling mode in which the agricultural machine is caused to perform self-traveling in a self-traveling area and a remote manipulation mode in which travel of the agricultural machine is controlled by remote manipulation. The controller is configured or programmed to disable a remote manipulation to cause the agricultural machine to enter the forbidden area, to set at least a portion of the self-traveling area as the permitted area and an outside of the self-traveling area as the forbidden area, and to cause the storage to store the position of the permitted area and the position of the forbidden area.
