Agricultural Visualization Device Spatial Control Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visualization systems for agricultural working machines lack a direct link between control operations and the vehicle's position, limiting operator awareness and comfort, especially when the machine operates on predefined routes autonomously.
Innovation Solution
A device that visualizes control operations by displaying graphic images of the driving path, with icons representing each operation, allowing operators to monitor and potentially abort or delay actions, and integrates with GPS or sensor-based track-following systems for autonomous navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display unit visualizes control operations of a preprogrammed control sequence, then the driver is informed of the control processes to be carried out, but there is no direct link between the control operations and the momentary position of the agricultural vehicle on the territory to be worked
Solution Approach 1:
The patent transitions from a traditional linear list of control operations to a spatial visualization where control operation icons are distributed along the driving path on a map. This dimensional change allows operators to simultaneously perceive the temporal sequence of operations and their spatial correspondence to the vehicle's position and destination, resolving the contradiction between information completeness and operational clarity.
Solution Approach 2:
The driving path visualization serves as an intermediary element that connects the abstract control operations with the concrete vehicle position and destination. By displaying control operation icons along the visualized path, the system creates a direct visual link between what the vehicle should do and where it is going, enabling operators to easily determine correspondence without additional complex displays.
2Ease of operation
If the driver is directly involved in the vehicle control process, then the driver can understand control operations, but the driver is not able to determine whether the control operations correspond with the momentary position of the vehicle
Solution Approach 1:
The system provides visual feedback by displaying the current control operation icon at the corresponding position on the visualized driving path. This feedback mechanism allows the driver to immediately see whether the vehicle's actual position and orientation match the expected position for the current control operation, enabling the driver to detect discrepancies without being overwhelmed by detailed control information.
3Productivity
If control operations are automated to relieve the driver of complex control processes, then complicated control operations can be automated, but the driver loses direct integration in the control process
Solution Approach 1:
The visualization system enables the automated control system to present itself in an intuitive manner. The driving path with distributed control operation icons allows the system to automatically guide the vehicle while providing clear, at-a-glance information about current and upcoming operations. This self-service approach maintains driver awareness and integration without requiring manual control, as the system presents its own operations in an easily interpretable format.

AI summary
A device for visualizing control operations of an agricultural working machine includes a visualization device that visualizes at least one driving path to be traveled is assigned to the agricultural working machine. Control operations are stored in graphic images and the graphic images are displayed in the visualization device along the driving path to be traveled in the order in which they are carried out, to maintain an operator in an informed state with respect to the control processes that are taking place.
