Combine Autonomous Driving With Hold-to-Run Travel Allowance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work vehicles can inadvertently initiate and continue autonomous travel due to accidental operation of the start button or touch screen, leading to unintended autonomous operations.
Innovation Solution
An autonomous driving method and system for work vehicles that include an autonomous travel allowance operation member and an autonomous travel control part, allowing controlled autonomous travel based on a preset travel route, preventing unintended travel by requiring intentional operation of the allowance member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple start button or touch screen operation is used to initiate autonomous travel, then the ease of operation is improved, but the reliability deteriorates due to accidental operations
Solution Approach 1:
The patent changes the operational parameter from a simple single-touch button or screen tap to a continuous operation requirement (holding the switch or dragging the slider for a specified period). This parameter change maintains ease of operation while preventing accidental activations, as intentional operations will naturally sustain the required state longer than accidental touches.
Solution Approach 2:
The patent introduces dynamic operation modes including a temporary autonomous travel mode (activated by holding a switch) and a continuous autonomous travel mode (activated by dragging a slider). The system dynamically adjusts its response based on the duration and type of user input, allowing flexible operation while preventing unintended activations through duration-based differentiation.
2Productivity
If autonomous travel is executed based on simple button press, then the productivity is improved, but the risk of unintended autonomous travel increases
Solution Approach 1:
The patent requires preliminary intentional action (holding the switch or dragging the slider for a specified duration) before autonomous travel begins. This preliminary action serves as a deliberate confirmation step, ensuring the operator intends to activate autonomous travel, thereby preventing unintended operations while maintaining productivity when properly activated.
Solution Approach 2:
The system provides feedback through the requirement of sustained operation (holding or dragging) before activation. This feedback mechanism confirms intentional user input by requiring the operator to maintain the activation state, providing a clear distinction between intentional and accidental operations while enabling efficient autonomous travel execution.
3Ease of operation
If the autonomous travel can be started by simple operation, then the ease of operation is improved, but the measurement precision of user intent deteriorates
Solution Approach 1:
The patent uses dynamic temporal measurement to distinguish user intent. By measuring the duration of the operation (holding time for switch, drag distance for slider), the system accurately measures user intent precision while maintaining ease of operation. Intentional operations naturally exceed the threshold duration, while accidental touches do not.

AI summary
A combine is a work vehicle that autonomously travels on the basis of a preset travel route, and is provided with an autonomous travel allowance switch, which is an autonomous travel allowance operation member that allows autonomous travel, and a control device that functions as an autonomous travel control part that controls autonomous travel based on the travel route. The autonomous travel control part executes autonomous travel based on the travel route while the autonomous travel allowance switch is being operated (pressed).
