Work Area Registration With Adjustable Headland Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating work routes for autonomously traveling work vehicles automatically determine the size of the headland area and work area, limiting the operator's ability to set these areas as desired, which restricts flexibility and safety in route planning.
Innovation Solution
An area registration method and system that allow operators to input setting information to change the sizes of both the work area and headland area independently, enabling flexible and safe route adjustments by including a vehicle information setting unit, a work area setting unit, a headland area setting unit, and a changing unit within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the headland area size is automatically determined based on vehicle information, then the work vehicle can ensure safety and adequate turning space, but the operator cannot set the headland area and work area as desired
Solution Approach 1:
The system allows dynamic switching between automatic area determination mode and manual area setting mode. In automatic mode, the headland area is determined based on vehicle information to ensure safety. In manual mode, operators can freely adjust the headland area and work area sizes according to their preferences. This dynamic flexibility resolves the contradiction between safety assurance and operator customization capability.
Solution Approach 2:
The system enables operators to change the parameters (sizes) of the headland area and work area after initial automatic determination. By allowing parameter adjustment, the system maintains the safety benefits of automatic determination while providing the adaptability for operator-specific requirements. The changing unit modifies the registered area parameters based on operator input.
2Ease of manufacture
If the work area size is automatically determined based on headland area, then the route generation is simplified, but the operator cannot adjust the work area to arbitrary size
Solution Approach 1:
The system provides dynamic control over area determination, allowing automatic determination for simplicity when needed, and manual adjustment for flexibility when needed. The changing unit enables operators to modify work area size independently of the automatic determination process, combining the benefits of both approaches.
3Productivity
If the headland area is set to minimum range for vehicle turning, then the work area is maximized, but the operator cannot set desired headland or work area sizes
Solution Approach 1:
The system allows operators to change the registered parameters of headland area and work area sizes after initial setting. This enables operators to adjust areas according to productivity requirements while maintaining the ability to optimize for other factors such as safety or operational preferences.

AI summary
An area registration method including setting information about a work vehicle that autonomously travels in a travel area; setting a work area which is included in the travel area and in which the work vehicle performs work; setting a headland area that is included in the travel area and is located on the outer side of the work area; and, when an operation for inputting the set information of the headland area is received after the work area and the headland area have been set, changing the sizes of the work area and the headland area on the basis of the inputted set information.
