Work Vehicle Auto-Run Control for Positional Deviation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic run technologies for work vehicles allow operators to optionally set correction amounts, leading to unstable vehicle behavior and deteriorated work accuracy when correction amounts are larger than necessary.
Innovation Solution
An automatic run method, system, and program that cause a work vehicle to automatically follow a target route, receive correcting operations from an operator, and prohibit the vehicle's correcting action when the positional deviation exceeds a threshold value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator can optionally set the correction amount, then the ease of operation is improved, but the stability of the work vehicle's behavior deteriorates
Solution Approach 1:
The system changes the parameter of correction amount from being freely settable by the operator to being automatically determined based on the actual positional deviation. The control unit calculates the appropriate correction amount by comparing the work vehicle's current position with the target route, thereby optimizing both operational ease and behavioral stability.
2Speed
If the correction amount is larger than necessary, then the correcting action response is improved, but the work accuracy deteriorates
Solution Approach 1:
The system implements feedback control by continuously monitoring the work vehicle's actual position relative to the target route and automatically adjusting the correction amount. The control unit receives positional deviation information, calculates the appropriate correction, and applies it to the steering control, ensuring both rapid response and high precision without operator intervention.
3Reliability
If the operator sets a large correction amount, then the correcting effect is improved, but the work efficiency deteriorates
Solution Approach 1:
The system performs self-correction by automatically determining and applying the appropriate correction amount based on real-time positional data. The control unit independently calculates the optimal correction without requiring operator input, thereby maintaining reliable correcting effects while improving work efficiency through automated decision-making.

AI summary
[Problem] To provide an automatic run method, an automatic run system, and an automatic run program that are capable of suppressing a deteriorated work efficiency seen when correcting a positional deviation of a work vehicle. [Solution] A run processing unit 111 causes a work vehicle 10 to automatically run following a target route R. A reception processing unit 112 receives, from an operator, a correcting operation that corrects a positional deviation L between the work vehicle 10 and the target route R, and A offset processing unit 113 prohibits, when the positional deviation L is a threshold value Lth or over, the work vehicle 10's correcting action that is in response to the correcting operation.
