Planter Controller Speed Control for Seed Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural implement operators face significant fatigue and inefficiency due to the need for manual adjustment of work vehicle speed to optimize planting parameters, such as seed depth and spacing, which can lead to suboptimal productivity and efficiency, especially with inexperienced operators.
Innovation Solution
A system and method for implement-based speed control, where a planter controller monitors operating parameters like down force and seed-related parameters, comparing them to predetermined thresholds, and adjusts the work vehicle's speed automatically to maintain optimal planting conditions by transmitting speed control requests to the vehicle controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual speed control is used by the operator, then the operator can adjust planting parameters, but operator fatigue increases and planting efficiency decreases
Solution Approach 1:
The planter system automatically monitors its own operating parameters (down force, seed depth, spacing) and self-regulates the work vehicle speed without operator intervention. The planter controller receives data from sensors and autonomously adjusts speed to maintain optimal planting conditions, allowing the system to serve itself rather than requiring continuous manual control.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where sensors continuously monitor planting parameters (down force, seed depth, spacing), compare them against target values, and automatically adjust work vehicle speed based on the deviations detected. This feedback loop eliminates the need for manual monitoring and adjustment while maintaining optimal planting efficiency.
2Ease of operation
If inexperienced operators manually control speed, then simple operation is maintained, but planting precision deteriorates
Solution Approach 1:
The patent replaces the manual mechanical control system with an electronic control system. The planter controller electronically monitors planting parameters through sensors and automatically transmits speed adjustment commands to the work vehicle, substituting human manual control with an automated electronic control mechanism that ensures consistent precision regardless of operator experience.
Solution Approach 2:
The system performs self-monitoring and self-correction of planting parameters. The planter controller autonomously detects deviations in seed depth and spacing, then automatically adjusts work vehicle speed to correct these deviations, eliminating the need for operator skill while maintaining high planting precision.
3Productivity
If automatic speed control is implemented, then operator fatigue is reduced and planting efficiency improves, but system complexity increases
Solution Approach 1:
The planter controller serves multiple functions: it monitors down force, tracks seed depth, measures spacing between seeds, and controls work vehicle speed adjustment. By consolidating these multiple control functions into a single controller, the system achieves automatic speed control and improved planting efficiency without proportionally increasing overall system complexity.
Solution Approach 2:
The patent merges the speed control function with the existing planter control system. Rather than adding a completely separate speed control system, the planter controller is enhanced to include speed adjustment capabilities, combining planting parameter monitoring and speed control into an integrated system that manages complexity through consolidation.
4Manufacturing precision
If continuous monitoring of planting parameters is performed, then planting precision is maintained, but energy consumption increases
Solution Approach 1:
The planter controller monitors planting parameters at periodic intervals rather than continuously. Sensors take measurements at regular cycles during operation, allowing the system to maintain adequate planting precision while reducing the energy consumption associated with constant monitoring and data processing.

AI summary
In one aspect, a system for providing implement-based speed control for a work vehicle may include a planter controller provided in operative association with a planter towed by the work vehicle and a vehicle controller provided in operative association with the work vehicle. The planter controller may be configured to access an input associated with at least one predetermined threshold value for an operating parameter of the planter and monitor the operating parameter relative to the predetermined threshold value(s) as the planter is being towed at a current ground speed of the work vehicle. In addition, when the operating parameter differs from the predetermined threshold value(s), the planter controller may be configured to adjust a speed control request transmitted to the vehicle controller to cause the current ground speed of the work vehicle to be automatically increased or decreased between predetermined maximum and minimum speed values set for the work vehicle.
