Autonomous Work Vehicle Route Recovery After Path Deviation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles deviate from their travel routes during autonomous travel, necessitating manual operator intervention to correct the path, which decreases work efficiency.
Innovation Solution
The work vehicle is equipped with a travel control system that autonomously stops when it deviates from the route and resumes travel once a return condition is met, minimizing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the work vehicle stops autonomously when deviating from the travel route, then the reliability of autonomous travel is improved, but the productivity decreases due to frequent stopping
Solution Approach 1:
The work vehicle autonomously returns to the travel route using its own traveling unit without external assistance. The control unit automatically calculates the return route and controls the traveling unit to follow it, enabling the system to self-correct deviations without operator intervention or manual intervention, thus maintaining productivity while improving reliability
Solution Approach 2:
The control unit continuously monitors the position of the work vehicle relative to the travel route and provides feedback. When a deviation is detected, the system calculates a return route and executes it, creating a closed-loop control system that automatically corrects errors and maintains reliable autonomous operation without stopping
2Ease of operation
If manual operator intervention is required to correct path deviation, then the ease of operation is improved, but the productivity decreases due to operator time consumption
Solution Approach 1:
The work vehicle autonomously returns to the travel route using its own traveling unit without external assistance. The control unit automatically calculates the return route and controls the traveling unit to follow it, enabling the system to self-correct deviations without operator intervention or manual intervention, thus maintaining productivity while improving reliability
Solution Approach 2:
The control unit pre-calculates the return route to the travel route before the vehicle completes its deviation. By preparing the correction path in advance and executing it automatically, the system eliminates the need for operator intervention and prevents productivity loss that would occur with manual correction

AI summary
A travel control method for the work vehicle includes: causing the work vehicle to autonomously travel on a travel route (target route); causing the work vehicle 1 to stop autonomously traveling when the work vehicle deviates from the travel route while the work vehicle autonomously travels; and causing the work vehicle to return onto the travel route to restart autonomously traveling once a return condition is met while the work vehicle stops autonomously traveling.
