Work Vehicle Display Control Using Chair Position and Vehicle State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work vehicles with multiple implements face difficulties in maintaining visual contact with the entire work area due to the large size and configuration of the vehicles, which limits their ability to efficiently control and coordinate the display systems, especially when switching between different views.
Innovation Solution
A system and method that utilize a computing device to control a display system based on the position of the operator's chair and the operating state of the work vehicle, receiving inputs from chair position sensors and operator control devices to automatically display image data from cameras positioned at different ends of the vehicle, ensuring the operator has an optimal view of the relevant implement or area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imaging devices are provided to cover different work areas, then the operator can view different portions of the worksite, but the complexity of switching between different views increases
Solution Approach 1:
The display system automatically selects and switches between different camera views based on sensor inputs detecting chair position and implement state, eliminating the need for manual operator intervention to switch views. The system serves itself by autonomously determining which view to display based on predefined criteria linked to operational states.
Solution Approach 2:
The system changes display parameters (which camera view is shown) based on changes in operational parameters (chair position, implement state). When the chair rotates or the implement state changes, the display automatically transitions to show the appropriate view corresponding to the new parameter state.
2Adaptability or versatility
If the chair is made movable to face different ends of the vehicle, then the operator can face different implements, but it becomes more difficult to maintain visual contact with the entire work area
Solution Approach 1:
Imaging devices act as intermediaries between the operator and the work area. Instead of relying on direct line-of-sight, the operator views the work area through cameras positioned at different locations on the vehicle, which capture and transmit visual information to the display system.
Solution Approach 2:
The imaging devices create visual copies of different work area portions and display them on screens in the cab. The operator sees replicated images of the work area rather than the actual physical view, allowing multiple views to be presented simultaneously or switchably without the operator needing to physically reposition.
3Ease of operation
If manual switching between camera views is implemented, then the operator can select different views, but the operation becomes cumbersome and reduces efficiency
Solution Approach 1:
The display system automatically selects and switches between different camera views based on sensor inputs detecting chair position and implement state, eliminating the need for manual operator intervention to switch views. The system serves itself by autonomously determining which view to display based on predefined criteria linked to operational states.
Solution Approach 2:
The system continuously monitors feedback from sensors about chair position and implement state, and uses this feedback to automatically adjust the display. The closed-loop system responds to operational conditions in real-time, switching views proactively based on detected state changes rather than waiting for manual commands.

AI summary
A method for automatically controlling a display system for a work vehicle having a first implement supported at a first end of a chassis, a second implement supported at a second end of the chassis, and a chair that is selectively movable between a first position oriented toward the first end of the work vehicle and a second position oriented toward the second end of the work vehicle. The method may include receiving an input indicative of a position of the chair and an input indicative of an operating state of the work vehicle. Additionally, the method may include controlling a display device to display image data from an imaging device associated with a first portion of a worksite or a second portion of the worksite based at least in part on the position of the chair and the operating state of the work vehicle.
