Field Route Generation Using Auto-Registered Reference Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional route generation methods for autonomous work vehicles in fields have low workability due to the risk of operators forgetting to register reference points during teaching travel, leading to incomplete target route generation and the need for repeated teaching operations.
Innovation Solution
A route generation method that acquires position information of a work vehicle and registers a reference point based on traveled distance or elapsed time, generating a target route autonomously to improve workability and reduce operator errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually registers reference start point and reference end point during teaching travel, then the target route can be generated, but the operator may forget to perform the registration operation when performing work simultaneously, resulting in low workability
Solution Approach 1:
The system automatically detects the work vehicle's position and autonomously registers reference points without requiring manual operator input. The registration is triggered automatically when the vehicle reaches predetermined positions during teaching travel, eliminating the need for the operator to manually register points while performing work operations.
Solution Approach 2:
The system provides automatic feedback by detecting the vehicle's position and notifying the operator when reference points have been registered. This feedback mechanism ensures the operator is aware of the registration status without needing to continuously monitor or manually confirm each registration, improving both reliability and ease of operation.
2Productivity
If the operator performs teaching travel while performing predetermined work, then productivity increases, but the likelihood of forgetting to register reference points increases, requiring repeated teaching operations
Solution Approach 1:
The system performs automatic reference point registration without requiring the operator to stop work operations. The vehicle's own movement and position data are used to trigger registration, allowing the operator to maintain continuous work operations while the system handles route generation autonomously.
Solution Approach 2:
The system pre-defines the positions where reference points should be registered based on the teaching route. As the vehicle travels along the teaching route, the system automatically registers points at the predetermined positions, ensuring complete registration before the teaching operation concludes, thus avoiding the need for repeated operations.
3Ease of manufacture
If manual registration of reference points is required, then route generation can be performed, but the operation becomes complex and error-prone when combined with work operations
Solution Approach 1:
The system replaces the manual mechanical operation of registering reference points with an automated electronic detection and registration system. The vehicle's position is automatically detected using positioning technology, and reference points are registered through electronic processing, eliminating the need for manual operator actions and reducing operational complexity.
Solution Approach 2:
The route generation system serves itself by automatically detecting positions and registering reference points without external manual intervention. This self-service capability simplifies the overall process, making it easier to perform while maintaining accuracy and reducing the potential for errors.

AI summary
[Problem] To provide a route generation method, a route generation system, and a route generation program that are capable of improving workability of work that generates a target route that causes a work vehicle to travel autonomously in a field. [Solution] An acquisition processing unit 715 acquires position information of a predetermined position of a work vehicle 10 in a field F. A registration processing unit 716 registers the predetermined position as a reference point when the work vehicle 10 has traveled a predetermined distance from the predetermined position, or when a predetermined time has elapsed since the work vehicle 10 started to travel from the predetermined position. A generation processing unit 714 generates a target route R based on the reference point.
