Work Vehicle Control Lever Integrated Automatic Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control systems for work vehicles require operators to release the operating lever to use the automatic control member, leading to complex operations and a risk of unintentional movements during automatic control functions, which can compromise construction quality.
Innovation Solution
A control system where the automatic control member is integrated onto the operating lever, allowing operators to perform automatic control functions while maintaining hold of the lever, with conditions ensuring that unintended movements are prevented during erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating member for automatic control is provided on the console box separate from the operating lever, then the automatic control function can be operated, but the operator must release the operating lever which increases operation complexity and motion requirements
Solution Approach 1:
The patent merges the automatic control operating member with the operating lever by providing the operating member on a surface of the operating lever itself. This integration allows the operator to operate the automatic control function while maintaining hold of the operating lever, eliminating the need to release the lever and reducing the number of motions required.
2Ease of operation
If the operating member is provided on the operating lever, then operation becomes simpler, but the operating lever may be moved by erroneous operation during automatic control function operation
Solution Approach 1:
The patent applies preliminary anti-action by configuring the controller to detect when the operating lever is being operated during automatic control function operation. When such concurrent operation is detected, the controller suppresses the automatic control function, preventing erroneous movements of the work implement before they can occur.
3Productivity
If the automatic control function is performed during lever operation, then construction work can be performed, but unintentional motion of the work implement may occur compromising construction quality
Solution Approach 1:
The patent implements feedback by having the controller continuously monitor the position and operation state of the operating lever. When the lever is detected to be in a non-neutral position or being operated during automatic control function operation, the controller provides feedback by suppressing the automatic control function, thereby preventing unintentional motion and ensuring construction quality.

AI summary
A control system for a work vehicle having a work implement includes a first operating lever for the work implement, a first operating member and a controller. The first operating member is provided on the first operating lever. The controller is configured to perform an automatic control of the work implement. The controller is configured to perform a function of the automatic control, which is allocated to the first operating member, in response to operating the first operating member when a performance condition, including that the first operating lever is located in a neutral position thereof, is satisfied.
