Remote Vehicle Route Display for Easier Teleoperation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for working vehicles lack the capability for remote manipulation and provide insufficient information to human remote operators, making remote operation difficult.
Innovation Solution
A remote device and system that includes a display to show the vehicle's travel direction, a controller to change the route display based on manipulation instructions, and a communicator to receive position and image information, enabling remote manipulation by displaying model and actual travel routes with varying line characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote operation is implemented without teaching information, then the system structure is simple, but the ease of operation deteriorates because human remote manipulators cannot effectively control the vehicle
Solution Approach 1:
The system performs preliminary actions by automatically capturing and storing teaching information (images, operation data, position data) during manual vehicle operation. This pre-captured information is then provided to remote manipulators during remote operation, eliminating the need for complex real-time communication systems while improving ease of operation.
Solution Approach 2:
The system creates copies of the manual operation process by capturing teaching information that replicates the operator's perspective and actions. Remote manipulators use these copied information (images, operation data) to reproduce the same operational effects as manual control, simplifying the remote control system while maintaining operational effectiveness.
2Ease of operation
If detailed teaching information is provided during remote manipulation, then the ease of operation improves, but the loss of time increases due to information processing overhead
Solution Approach 1:
The system extracts only the essential teaching information needed for remote operation (images, operation data, position data) from the complete operational context. By selecting and transmitting only these critical elements rather than all possible data, the system improves ease of operation while minimizing information processing time and data transmission overhead.
3Ease of operation
If the travel route is displayed in a fixed manner, then the device complexity is low, but the ease of operation deteriorates because remote manipulators cannot adapt to different operation stages
Solution Approach 1:
The route display dynamically changes based on the vehicle's position and operation stage. The system automatically adjusts display parameters (such as highlighting upcoming routes or showing detailed paths) according to real-time position data and teaching information, improving adaptability for remote manipulators while using simple automatic control logic rather than complex manual adjustment mechanisms.

AI summary
Remote manipulation is assisted (supported). A remote manipulation system (100) includes a remote manipulator (35) to remotely manipulate a working vehicle (1), a display (34) to display an image of an area in the direction of travel of the working vehicle (1) captured during the remote manipulation, and a controller (31) configured or programmed to, according to information for teaching of remote manipulation of the working vehicle (1), cause the display (34) to display a travel route for the working vehicle (1) to travel and change a manner in which the travel route is displayed.
