Turn Path Pattern Selection for Sharp Agricultural Vehicle Turns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural vehicle guidance systems struggle to accurately navigate sharp turns in guidance paths, often requiring manual intervention or backup maneuvers, which can lead to inefficiencies and gaps in field coverage.
Innovation Solution
The system includes input interface circuitry to obtain a guidance path, turn identification circuitry to detect sharp turns, and turn pattern selection circuitry to choose a predetermined turn pattern that satisfies a condition, such as avoiding turn radii less than the vehicle's minimum turn radius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle follows the guidance path directly, then the navigation simplicity is improved, but the vehicle cannot accurately navigate sharp turns where the turn radius is less than the minimum turn radius
Solution Approach 1:
The system performs preliminary identification of sharp turns in the guidance path before the vehicle reaches them. By detecting turns where the turn radius is less than the minimum turn radius in advance, the system can prepare and execute backup maneuvers proactively, ensuring accurate navigation through sharp turns while maintaining overall navigation simplicity.
2Reliability
If manual intervention is used for sharp turns, then the turn navigation accuracy is improved, but the productivity decreases due to the need for manual operation
Solution Approach 1:
The system implements automated detection and handling of sharp turns using onboard sensors and processing circuitry. The system autonomously identifies sharp turns, selects appropriate backup maneuvers, and executes them without requiring manual operator intervention. This maintains high turn navigation accuracy while preserving productivity by keeping the operation fully automated.
3Reliability
If backup maneuvers are executed for sharp turns, then the turn navigation accuracy is improved, but the time consumption increases
Solution Approach 1:
The system identifies sharp turns in advance using onboard sensors and processing circuitry, allowing it to plan and execute backup maneuvers efficiently. By detecting turns where the radius is less than the minimum turn radius before reaching them, the system can smoothly transition to pre-planned backup paths, reducing the time penalty compared to reactive maneuvers.
4Ease of operation
If the vehicle uses a fixed turn radius, then the ease of operation is improved, but the adaptability to different turn conditions decreases
Solution Approach 1:
The system dynamically selects from multiple predetermined turn patterns based on the specific conditions of each sharp turn detected in the guidance path. Rather than using a fixed turn radius, the processing circuitry evaluates turn characteristics and automatically chooses the most appropriate turn pattern from available options, providing adaptability to different turn conditions while maintaining ease of operation through automated selection.
