Work Vehicle Row-Stop Positioning From Worksite Outline Data

Solution Overview

Problem

Existing work vehicle control systems lack a specified position for executing row-stop control, leading to suboptimal 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 based on this information to execute row-stop control, ensuring efficient work execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If row-stop control is executed without specifying an appropriate position, then the work vehicle can perform row-stop control to ensure work width along the periphery, but work efficiency for the whole area of the work site cannot be improved

Engineering Contradiction:

Improvework efficiencyVSAvoidcontrol complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary action by acquiring outline information of the work site in advance and pre-calculating the appropriate row-stop position based on the vehicle's travel route and work width. This allows the control system to determine the optimal position for row-stop control before the vehicle reaches it, ensuring both work efficiency improvement and proper work width maintenance along the periphery

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the work vehicle travels along the target travel route for post process, then it can perform work along the ridge side, but row-stop control must be executed for parts overlapping with the work width to be ensured along the periphery

Engineering Contradiction:

Improvework coverageVSAvoidcontrol operation

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system uses feedback by continuously monitoring the work vehicle's current position, travel route, and work width requirements. Based on this feedback, the control system dynamically determines the appropriate row-stop position where the vehicle should execute row-stop control to ensure proper work width along the periphery while maintaining work coverage along the ridge side

Inventive Principle:

Principle #23Feedback

3Productivity

If no specific row-stop position is specified, then the control system is simpler to operate, but work efficiency for the whole area cannot be optimized

Engineering Contradiction:

Improveoverall work efficiencyVSAvoidposition information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system performs preliminary action by acquiring outline information of the work site in advance and pre-calculating the appropriate row-stop position based on the vehicle's travel route and work width. This allows the control system to determine the optimal position for row-stop control before the vehicle reaches it, ensuring both work efficiency improvement and proper work width maintenance along the periphery

AI summary

[Problem] To provide a control method of a work vehicle, a control program for a work vehicle, a control system for a work vehicle, and a work system, capable of improving work efficiency for a work site. [Solution] The control method of a work vehicle 10 is a control method of the work vehicle 10, capable of working on a plurality of work rows Vr1 to Vr8 aligned in a direction intersecting a traveling direction, while traveling in a work site F1. This control method has acquisition of outline information based on an outline of the work site F1 and setting of a row-stop position for executing row-stop control that sets a part of a plurality of work rows Vr1 to Vr8 to non-work in the work site F1 on the basis of the outline information.
