Acquisition Path Display for Real-Time Guidance Path Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural vehicle guidance systems do not provide real-time visualization of the transition from the current location to a desired guidance path, relying on qualitative, subjective user feedback for path acquisition, and require manual user intervention for path updates.
Innovation Solution
A system and method for displaying acquisition paths in real-time, dynamically updating based on vehicle position relative to guidance paths, including heading error, speed, and direction, allowing users to see the vehicle's trajectory when steering automation is engaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional agricultural vehicle guidance systems are used, then the system complexity is reduced, but the information completeness for path acquisition is insufficient
Solution Approach 1:
The patent creates a visual copy of the acquisition path by displaying a calculated trajectory on the user interface. This virtual representation allows users to see the planned path without adding physical complexity to the vehicle's guidance mechanisms. The system copies the essential path information into a visual format that can be easily interpreted by the operator.
Solution Approach 2:
The patent introduces a display controller as an intermediary component that calculates and presents path acquisition information. This mediator translates complex sensor data and guidance calculations into a simple visual representation on the user interface, bridging the gap between complex system operations and user understanding without requiring direct modification of the core guidance system.
2Measurement precision
If real-time path updates are implemented, then the measurement precision of vehicle position is improved, but the device complexity increases
Solution Approach 1:
The patent implements continuous real-time updates of the acquisition path display by continuously calculating the vehicle's position relative to the guidance path and refreshing the visual representation. This continuous action maintains high measurement precision without requiring discrete, complex intervention points. The system continuously processes position data and updates the display in real-time, creating a seamless feedback loop.
Solution Approach 2:
The display controller automatically calculates and updates the acquisition path without requiring manual user intervention. The system self-manages the continuous monitoring of vehicle position, recalculation of the optimal path, and refreshment of the visual display. This self-service capability maintains high precision while minimizing the complexity of user interaction and system control architecture.
3Productivity
If manual user intervention is required for path updates, then the device complexity is reduced, but the productivity of path acquisition is lowered
Solution Approach 1:
The patent implements an automated feedback loop where the display controller continuously monitors the vehicle's actual position, compares it to the planned acquisition path, and automatically recalculates and displays updated paths. This closed-loop feedback system eliminates the need for manual path updates, significantly increasing productivity. The feedback mechanism automatically adjusts to changing conditions without requiring additional complex hardware or user intervention.
Solution Approach 2:
The system pre-calculates and displays the acquisition path before the vehicle begins following it, allowing users to see the planned trajectory in advance. This preliminary action enables proactive adjustment and understanding of the path acquisition process. The system continuously performs preliminary calculations for upcoming path segments, maintaining high productivity by having path information ready before it is needed.

AI summary
Methods, apparatus, systems, and articles of manufacture are disclosed to display acquisition paths. An example apparatus includes a display handler to, in response to a directional condition of an autonomous vehicle satisfying a threshold, render an acquisition path for the autonomous vehicle, the acquisition path specifying a route along which the autonomous vehicle is to travel to acquire a guidance path; and a vehicle condition controller to, in response to determining that a real time display criterion is satisfied, redetermine whether the directional condition of the autonomous vehicle satisfies the threshold to cause the display handler to re-render the acquisition path.
