Working Vehicle Route Layout for Accurate Field Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traveling route setting devices for working vehicles do not accurately reflect user requests, leading to deviations in the position, angle, and route of the target traveling route, resulting in ineffective work performance.
Innovation Solution
The device includes a work region setting portion, initial route generation, work route generation, connection route generation, route exclusion, reference route selection, traveling trajectory acquisition, and traveling route changing portions to ensure the target traveling route aligns with user-defined requirements, adjusting for changes in work conditions and ensuring the route remains within the designated work region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If candidate target traveling routes are generated based on working vehicle information and working machine specifications, then multiple route options are provided for user selection, but the routes may deviate from the user's actual work requirements and preferences
Solution Approach 1:
The system performs preliminary route generation based on vehicle and machine specifications before user operation, providing candidate routes in advance. This allows the system to prepare multiple route options that consider technical constraints while awaiting user confirmation or modification.
Solution Approach 2:
The system incorporates user feedback by allowing selection and modification of generated routes. The user can confirm satisfactory routes or request alternative routes, creating a feedback loop that refines the route generation to match actual user requirements and preferences.
2Adaptability or versatility
If the system provides multiple candidate target traveling routes for selection, then route versatility is improved, but the complexity of route setting and selection increases
Solution Approach 1:
The route setting process is segmented into distinct phases: automatic generation of candidate routes based on technical parameters, display of options to the user, and selection/confirmation step. This segmentation simplifies the overall complexity by breaking down the route setting task into manageable, sequential steps.
3Extent of automation
If the target traveling route is set without considering user's actual work location and preferences, then route generation is simplified and automated, but the route position and angle deviate from the desired work area
Solution Approach 1:
User confirmation and selection of routes serve as feedback that corrects potential deviations from actual work requirements. The system automates route generation but uses user feedback to ensure alignment accuracy with the desired work area.
Solution Approach 2:
The system performs preliminary automated route generation considering technical constraints, then allows user adjustment. This preliminary action provides a solid technical foundation while leaving room for user refinement to achieve precise alignment with work requirements.

AI summary
Provided are a work region setting portion which sets, within a traveling region, a work region for a working vehicle to perform predetermined work; and a traveling route setting portion which sets, within the traveling region, a target traveling route to make the working vehicle travel automatically. The traveling route setting portion includes: an initial route generation portion which generates an initial route based on a trajectory formed by the working vehicle traveling in the traveling region; a work route generation portion which generates work routes arranged in a parallel arrangement direction orthogonal to an extension direction; and a connection route generation portion which generates connection routes connecting, at either side of the work region, routes adjacent in the parallel arrangement direction among the initial route and the work routes. The target traveling route including the initial route, the work routes, and the connection routes is thereby set.
