Work Vehicle Parameter Updating via Built-In Display Controls

Solution Overview

Problem

Existing parameter management systems for work vehicles are unreliable and cumbersome, requiring external devices like maintenance PCs for parameter updating, which is inconvenient and prone to errors.

Innovation Solution

A parameter management system integrated into the work vehicle, featuring a display panel, non-volatile memory, and a manual operation member, allowing maintenance workers to update control parameters directly on the display panel without external devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a maintenance PC or external device is used to update parameters, then reliability of parameter updating is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:

Improveparameter updating reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the parameter updating function with the existing display panel and operation members already present in the work vehicle. The control unit integrates both parameter display and parameter setting capabilities, merging what were previously separate functions (maintenance PC connection and vehicle operation) into a unified system that uses the vehicle's own display and control interfaces.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The work vehicle performs parameter updating using its own built-in display panel and operation members, eliminating the need for external maintenance PCs. The system serves itself by providing parameter display and update capabilities through its existing user interface components, making the maintenance process self-contained and more reliable.

Inventive Principle:

Principle #25Self-service

2Reliability

If a maintenance PC is connected to update parameters, then parameter updating reliability is improved, but ease of operation deteriorates

AI summary

A parameter management system includes a display panel 8B provided for the work vehicle and configured to display information on a state of the work vehicle; a non-volatile memory 55a configured to store a plurality of control parameters each for use to control a device provided for the work vehicle; a manual operation member 8a for use to select a control parameter to be displayed on the display panel; and a changed parameter manager 55b configured to, in response to an operation of the manual operation member 8a, set a value for a control parameter displayed on the display panel 8B and write the value into the non-volatile memory 55a.
