Relative Positioning System for Implement Control Resume Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for machines and implements lack accuracy in controlling implement positions, especially during interruptions or piecemeal completion of tasks, as they do not account for stoppages or resume operations effectively.
Innovation Solution
A control system that includes a relative positioning system with perception sensors to determine implement positioning relative to past operations, allowing the controller to determine current progress, end positions, and resume positions based on pre-determined control plans, and generate implement control signals for actuators to accurately position the implement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional control systems transmit signals for machine movement to control implement elements, then basic control functionality is achieved, but control accuracy deteriorates and the system cannot account for stoppages or resume operations
Solution Approach 1:
The control system continuously receives feedback from perception sensors that monitor the implement's actual position and orientation. This feedback loop enables the controller to compare actual operation with the control plan, detect stoppages, and calculate accurate resume positions, thereby maintaining high control accuracy without excessive complexity
Solution Approach 2:
The system pre-calculates resume positions and stores control plans before interruptions occur. When a stoppage is detected, the controller already has the necessary information to quickly determine where to resume operations, eliminating the need for complex real-time calculations during interruptions
2Ease of operation
If control systems operate without relative positioning to past operations, then simpler control is maintained, but the ability to resume operations accurately deteriorates
Solution Approach 1:
The perception sensors create a digital copy or map of the terrain and past implement positions. This copied information is stored and used to determine relative positioning, enabling accurate resumption of operations without requiring complex absolute positioning measurements
3Productivity
If control systems do not track current progress relative to actual operation, then less processing is required, but the ability to determine resume positions deteriorates
Solution Approach 1:
The controller continuously compares the control plan with actual implement operation through feedback from perception sensors. This tracking ensures no loss of progress information and enables efficient determination of where to resume operations after interruptions

AI summary
A control system for controlling operation of an implement based, at least, on a pre-determined implement control plan, includes a relative positioning system, a controller, and one or more actuators. The relative positioning system is configured for determining positioning of the and utilize input from perception sensors to determine relative positioning signals. The controller is configured to determine a resume position for a next operation of the implement based on the predetermined implement control plan and at least one of the relative positioning signals and an end position of a previous operation of the implement. The controller may further be configured to determine implement control signals based on, at least, the resume position. The one or more actuators are each operatively associated with one or both of the implement and machine and configured to receive the implement control signals and position the implement based on the implement control signals.
