Remote Driving Display Cues for Working Vehicle Speed Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote manipulation of industrial vehicles, such as tractors, is challenging due to the lack of physical speed perception and clear environmental markers, making it difficult for operators to gauge speed changes, especially in open environments like pastures.
Innovation Solution
A remote control apparatus with a manipulator, communication module, and display that provides highlighted visual cues based on vehicle speed and acceleration, enhancing perceived speed through emphasized displays on a remote driving screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control of working vehicles is implemented, then operational flexibility and safety are improved, but the operator's ability to physically perceive vehicle speed deteriorates
Solution Approach 1:
The patent introduces an intermediary system consisting of display units that show virtual road markings and speed indicator marks. These visual intermediaries translate the actual vehicle speed into perceivable visual changes, allowing the remote operator to sense speed without physical feedback. The display unit acts as a mediator between the vehicle's motion and the operator's perception.
Solution Approach 2:
The patent creates a visual copy of the road environment by displaying virtual road markings that mimic actual road features. Additionally, it generates speed indicator marks that copy the concept of speed measurement through visual displacement. This copying approach allows the operator to perceive speed through visual analogues rather than direct physical sensation.
2Difficulty of detecting and measuring
If highlighted display is applied to enhance speed perception, then speed detectability is improved, but device complexity increases
Solution Approach 1:
The patent segments the speed indication function into distinct visual elements: virtual road markings that provide reference frames and separate speed indicator marks that show displacement. This segmentation allows each element to perform a specific function, making the overall system easier to implement and understand despite the added complexity.
Solution Approach 2:
The patent employs color changes and visual emphasis in the display to enhance speed perception. The highlighted display uses variations in color, brightness, or visual emphasis to make speed changes more apparent to the operator, providing an intuitive way to detect speed without complex instrumentation.
3Adaptability or versatility
If remote manipulation is used in open environments like pastures, then operational versatility is improved, but speed gauging difficulty increases due to lack of environmental markers
Solution Approach 1:
The patent creates artificial visual references by displaying virtual road markings and speed indicator marks on the display unit. These copied visual elements serve the same function as natural environmental markers would in a road environment, providing reference points against which speed can be gauged. This allows the system to function in open environments where natural markers are absent.
Solution Approach 2:
The display unit with virtual markings acts as an intermediary that creates an artificial reference environment. Instead of relying on actual environmental features, the system mediates the speed perception process by generating visual references that the operator can use to gauge speed, effectively creating a virtual environment for measurement.

AI summary
A remote control apparatus includes a manipulator to manipulate a working vehicle remotely, a communication module configured or programmed to receive traveling information that indicates a speed or an acceleration of the working vehicle, a display, and a controller configured or programmed to cause the display to perform highlighted display that changes in accordance with the traveling information when the working vehicle is driven remotely by using the manipulator.
