Work Vehicle Endpoint Actions for Autonomous-Manual Mode Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work vehicles that switch between autonomous and manual traveling modes face inefficiencies, including the need to temporarily stop the vehicle or work machine, which can be time-consuming and prone to oversight due to reliance on buzzer sounds for operation reminders.
Innovation Solution
A traveling control method and system that allows users to set specific actions for the work vehicle upon reaching the end of an autonomous travel route, such as outputting sounds or displaying messages, and switching to manual travel mode, improving operator efficiency and reducing the risk of missed notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator relies on buzzer sound to prompt switching operation, then the operator can be notified of the endpoint, but the operator may forget to perform the predetermined operation without noticing the buzzer sound, causing time loss and reduced productivity
Solution Approach 1:
The system implements feedback by detecting the operator's gaze direction through cameras and determining whether the operator has noticed the buzzer sound. Based on this feedback, the system automatically adjusts whether to execute the predetermined operation, ensuring reliable operation confirmation while maintaining productivity.
Solution Approach 2:
The system performs the predetermined operation automatically without requiring manual operator intervention. The work vehicle or work machine autonomously executes stopping or other predetermined actions based on gaze detection results, eliminating the need for the operator to manually respond to the buzzer sound.
2Ease of operation
If the operator needs to perform a predetermined operation when switching from autonomous to manual traveling, then the switching can be controlled, but it takes time and effort, reducing operational efficiency
Solution Approach 1:
The system automatically executes the predetermined operation (stopping the work vehicle or work machine) based on gaze detection results, eliminating the need for the operator to manually perform the switching operation. This self-service approach reduces both the time and effort required for mode switching.
Solution Approach 2:
The system performs the predetermined operation in advance based on the detection of the operator's gaze direction, before the operator would have time to manually respond. This preliminary action eliminates the time delay associated with manual operation.
3Productivity
If the system automatically executes predetermined operation without gaze confirmation, then productivity is improved, but the operator may not be aware of the system's action, reducing operational awareness
Solution Approach 1:
The system uses gaze detection as feedback to determine whether to execute the predetermined operation. By confirming the operator has noticed the buzzer sound through gaze direction analysis, the system maintains operational awareness while improving productivity through automated execution.

AI summary
An acceptance processing unit accepts, from a user, an operation to set each of a plurality of action items related to actions to be executed by a work vehicle when the work vehicle reaches a predetermined position corresponding to an end point of a work route on which the work vehicle is caused to autonomously travel. A setting processing unit sets each of the plurality of action items on the basis of the operation of the user.
