Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic Section Control (ASC) systems in agricultural work vehicles face performance degradation due to difficulties in predicting operator driving behaviors, particularly at transition boundaries, leading to mistimed commands and reduced efficiency in treating targeted areas.
Innovation Solution
A work vehicle display system that generates map displays with ASC lookahead symbology, projecting the future position and operative states of the work implement sections, allowing operators to visualize and adjust their driving behaviors to improve ASC performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ASC systems independently control implement sections to maximize coverage and precision, then manufacturing precision and productivity are improved, but operator awareness and control over driving behavior impact on ASC performance deteriorate
Solution Approach 1:
The system provides visual feedback through map displays showing current implement position, future projected position, and lookahead symbology that indicates anticipated implement states. This feedback loop enables operators to see the direct relationship between their driving behaviors and ASC performance, allowing them to make informed adjustments to maintain precision while preserving awareness.
Solution Approach 2:
The lookahead symbology displays projected future states of implement sections based on current driving behavior trends. By showing operators what will happen in the near future if current driving patterns continue, the system enables preliminary adjustments to driving behavior before precision degradation occurs, maintaining ASC performance while keeping operators informed.
2Productivity
If ASC systems control multiple implement sections independently, then productivity increases, but device complexity increases
Solution Approach 1:
The system creates visual copies or representations of implement positions and states on a map display interface. Rather than requiring operators to physically monitor multiple implement sections, the system generates graphical copies showing current and projected positions, allowing complex multi-section control to be monitored and adjusted through simplified visual representations.
3Productivity
If ASC systems operate at high speed to maximize productivity, then productivity improves, but measurement precision of operator driving behavior impact deteriorates
Solution Approach 1:
The lookahead symbology calculates and displays projected implement states based on current driving behavior trends before those behaviors actually impact ASC performance. By providing advance warning of future states, the system enables operators to adjust driving behaviors proactively, maintaining prediction accuracy even at high operating speeds where reactive adjustments would be too late.

AI summary
Work vehicle display systems and methods for generating map displays including automatic section control (ASC) lookahead symbology are disclosed. In embodiments, the work vehicle display system includes a display device on which a map display is generated, a position tracking data source, and a controller architecture. The controller architecture is operable in an ASC lookahead mode in which the controller architecture: (i) projects a future position of the work implement at a future timepoint based, at least in part, on data received from the position tracking data source; (ii) projects future operative states of the implement sections at the future timepoint when the implement sections are controlled by an ASC system; and (iii) generates ASC lookahead symbology on the map display visually indicating the projected future position of the work implement and the projected future operative states of the implement sections.
