Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work vehicles experience frequent positional and azimuth deviations during automatic travel, leading to repeated correction operations and decreased efficiency due to field conditions such as roughness or incline, which can hinder effective spraying operations.
Innovation Solution
An automatic traveling system that includes a correction processing unit to correct deviations using shift amounts from previous correction operations, ensuring the work vehicle maintains alignment with the target route by adjusting its position and azimuth based on past deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the work vehicle performs correction operations to maintain position and azimuth alignment with the target route, then the positioning accuracy is improved, but the work efficiency deteriorates due to repeated corrections in challenging field conditions
Solution Approach 1:
The system performs preliminary actions by storing shift amounts from previous correction operations and using them to predict and pre-adjust for expected deviations. The correction processing unit accumulates shift data over time and applies compensatory adjustments before deviations become significant, reducing the frequency of corrective interventions while maintaining positioning accuracy.
Solution Approach 2:
The system implements feedback by continuously monitoring positional and azimuthal deviations, storing correction data from previous operations, and using this historical information to adjust future corrections. The correction processing unit creates a closed-loop system where past correction effectiveness informs future correction strategies, optimizing the balance between maintaining accuracy and minimizing intervention frequency.

AI summary
[Problem] To provide an automatic traveling method, an automatic traveling program, an automatic traveling system, and a work vehicle, which can enhance a working efficiency of work by the work vehicle traveling automatically. [Solution] An automatic traveling method includes causing a work vehicle 10 to automatically travel along a target route in a work field, and executing a correction operation of correcting a deviation using a shift amount of the work vehicle 10 generated in the past correction operation when the deviation including at least a positional deviation or an azimuth deviation of the work vehicle 10 with respect to the target route exceeds a threshold.
