Master Work Vehicle Display Control for Slave State Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling master work vehicles and slave work vehicles in cooperative work environments lack effective means to communicate and display the state information of both vehicles, leading to potential confusion and inefficiencies in unmanned operations.
Innovation Solution
A controller for the master work vehicle equipped with a wireless circuit, acquisition circuit, message generation circuit, and display control circuit to receive and display state information from the slave work vehicle, allowing for clear differentiation between master and slave state messages through visual and auditory cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If state information from both master and slave work vehicles is displayed without differentiation, then the display content is simple, but confusion occurs between master and slave state messages
Solution Approach 1:
The patent applies color changes by displaying slave work vehicle state information in a first color and master work vehicle state information in a second color. This visual differentiation through color coding allows operators to immediately distinguish between messages from different vehicles, eliminating confusion while maintaining a relatively simple display interface.
Solution Approach 2:
The patent introduces an intermediary element (the controller with message generation and display control circuits) that receives state information from both vehicles, processes it with appropriate identifiers, and presents it in a differentiated manner. This intermediary processing layer manages the complexity internally while presenting a clear, differentiated output to the user.
2Loss of information
If visual and auditory cues are added to differentiate messages, then message differentiation is improved, but the system complexity increases
Solution Approach 1:
The patent segments the state information display into distinct channels: visual display with color coding, auditory output with different tones, and text messages with vehicle identifiers. This segmentation of information presentation channels allows comprehensive differentiation while organizing the complexity into manageable, independent components within the controller.
Solution Approach 2:
The patent changes multiple parameters of the information presentation simultaneously: visual parameter (color), auditory parameter (tone frequency), and textual parameter (message content with identifiers). By changing multiple parameters of the output signals, the system achieves comprehensive message differentiation through a single integrated controller design.

AI summary
A controller for a master work vehicle, includes a wireless circuit, an acquisition circuit, a message generation circuit, and a display control circuit. The wireless circuit is to receive, from a slave work vehicle configured to travel automatically, first information indicating a state of work travel of the slave work vehicle. The master work vehicle is configured to work in cooperation with the slave work vehicle. The acquisition circuit is configured to acquire second information indicating a state of work travel of the master work vehicle. The message generation circuit is configured to generate a first message based on the first information and a second message based on the second information. The display control circuit is configured to control a display to display the first message and the second message.
