Autonomous Work Vehicle Control for Multi-Implement Field Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles, such as tractors, are limited in their ability to perform work across the entire agricultural field due to the type of working device used, often failing to cover the entire area effectively when equipped with multiple working implements.
Innovation Solution
A work vehicle system that includes a traveling vehicle body, a coupler for attaching working devices with multiple implements, an automatic operation controller, and a work setting controller to set precise work start and end positions based on the implements, allowing for accurate work execution across the field by creating a planned traveling route and setting work areas and turning zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a working device with multiple working implements is used to increase work coverage, then the work area coverage is improved, but the precision of work position control deteriorates
Solution Approach 1:
The patent segments the work control system by setting different work start and end positions for each individual working implement within the working device. This allows each implement to be controlled independently, maintaining precision while managing multiple implements simultaneously. The controller divides the overall work area into multiple controlled zones corresponding to each implement's operational range.
2Productivity
If automatic operation is implemented to improve work efficiency, then productivity is improved, but the complexity of the control system increases
Solution Approach 1:
The patent applies preliminary action by pre-setting the work start and end positions for each working implement before automatic operation begins. The control system is configured in advance with the specific positions where each implement should start and end its work, allowing the automatic operation to execute smoothly without real-time complex decision-making, thus reducing operational complexity while maintaining high productivity.
3Device complexity
If the work start and end positions are set uniformly for all implements, then the control system is simplified, but the work quality deteriorates due to inability to account for different implement characteristics
Solution Approach 1:
The patent applies local quality by assigning specific work start and end positions tailored to each working implement's characteristics and operational requirements. Rather than using a uniform control approach, the system customizes control parameters for each implement, ensuring optimal work quality for each while maintaining overall system coordination through the central controller.
