Work Vehicle Row-Stop Control Using Field Outline Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing control methods for work vehicles lack a specified position for executing row-stop control, which hinders the improvement of work efficiency across the entire work site.
Innovation Solution
A control method for work vehicles that acquires outline information of the work site and sets a row-stop position for executing row-stop control, allowing parts of the work rows to be set to non-work based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If row-stop control is executed without specifying an appropriate position, then the work vehicle can operate flexibly, but work efficiency for the whole area of the work site cannot be improved
Solution Approach 1:
The control device automatically determines and executes row-stop control without operator intervention. The system uses acquisition processing to obtain outline information of the work site and automatically sets row-stop positions, eliminating dependency on operator skill levels and enabling consistent optimization of work efficiency across the entire work site
Solution Approach 2:
The control device performs preliminary acquisition of outline information about the work site boundaries and characteristics before executing the work. Based on this pre-acquired information, the system pre-determines optimal row-stop positions to ensure complete area coverage while maintaining high work efficiency
2Manufacturing precision
If row-stop control is executed to ensure work width along the periphery of the ridge side, then appropriate work width is maintained, but the position for executing row-stop control is not specified
Solution Approach 1:
The control device uses feedback from the acquired outline information of the work site to automatically determine precise row-stop positions. The system continuously monitors the work site boundaries and adjusts row-stop positions accordingly, ensuring both precise work width maintenance and complete position information is available for optimization
Solution Approach 2:
The system transitions from one-dimensional work row control to two-dimensional spatial control by incorporating outline information of the entire work site. This dimensional expansion enables the control device to determine optimal row-stop positions that consider both work width requirements and overall area coverage efficiency

AI summary
The control method of a work vehicle is a control method of the work vehicle, capable of working on a plurality of work rows aligned in a direction intersecting a traveling direction, while traveling in a work site. This control method has acquisition of outline information based on an outline of the work site and setting of a row-stop position for executing row-stop control that sets a part of a plurality of work rows to non-work in the work site on the basis of the outline information.
