Dual-Mode Work Vehicle Control When Remote Operation Fails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles face difficulty in being moved when the remote operation device fails or experiences power shortages, necessitating the use of alternative devices for manual operation.
Innovation Solution
A work vehicle equipped with both a remote operation device and an in-vehicle operation device, allowing for two operation modes: one using the remote device and another using the in-vehicle device, ensuring mobility in both scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the traveling machine body is operated using only a remote operation device, then ease of operation is improved, but reliability deteriorates when the remote device fails or experiences power shortage
Solution Approach 1:
The work vehicle is equipped with both a remote operation device and an in-vehicle operation device, allowing the traveling machine body to be operated through multiple channels. This multi-functionality ensures that if one operation device fails or experiences power shortage, the other can be used as a backup, thereby maintaining reliability while preserving ease of operation.
2Device complexity
If only a remote operation device is provided, then device complexity is reduced, but adaptability deteriorates when remote operation is unavailable
Solution Approach 1:
The system provides both remote and in-vehicle operation devices, enabling the work vehicle to adapt to different operational scenarios. Whether the operator prefers remote control or direct in-vehicle operation, the system can accommodate both modes, enhancing adaptability without excessive complexity.
Solution Approach 2:
The work vehicle dynamically switches between remote operation mode and in-vehicle operation mode based on availability and operational needs. The control system can transition between these modes flexibly, allowing the vehicle to adapt its operation method in real-time according to the situation.

AI summary
A work vehicle includes a traveling machine body, an in-vehicle operation device that is installed in the traveling machine body and that operates the traveling machine body, and a remote operation device that is provided separately from the traveling machine body and that operates the traveling machine body. The work vehicle has a first operation mode for operating the traveling machine body using the remote operation device and a second operation mode for operating the traveling machine body using the in-vehicle operation device.
