Work Vehicle Centralized Interlocking Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work vehicles lack a unit for operating and displaying the interlocking state with attached working machines, requiring operators to leave the vehicle to check and manage interlocking status, especially when multiple working machines are attached, leading to inefficiencies and increased operator workload.
Innovation Solution
A work vehicle equipped with a display unit to show attached and interlocked working machines, an operation unit for selecting and controlling the interlocking status, and a control unit to manage the interlocking of working machines, allowing operators to check and set interlocking states from the vehicle, including features like a transmission lever with assigned switches for specific functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the interlocking state is managed only on the working machine side, then the working machine can independently control its interlocking status, but the operator must leave the work vehicle to check and operate the interlocking state, increasing operator workload and reducing efficiency
Solution Approach 1:
The patent merges the interlocking control functionality from the working machine side to the work vehicle side by integrating a display unit and operation unit into the work vehicle's control system. This allows the operator to check and control the interlocking state of multiple working machines directly from the work vehicle without needing to physically move to each working machine, thereby improving ease of operation and reducing time loss.
2Adaptability or versatility
If multiple working machines are attached to the work vehicle, then the work vehicle can perform diverse tasks, but the operator needs to move to and check each working machine separately, increasing operational complexity
Solution Approach 1:
The patent implements a universal control system on the work vehicle that can manage the interlocking state of multiple different types of working machines through a single display unit and operation unit. The system detects and displays the interlocking status of various attached working machines (such as loaders, sprayers, broadcasters) and allows centralized control, making the system adaptable to multiple working machines while simplifying the operational procedure.
3Reliability
If the interlocking control is distributed to each working machine, then each working machine can independently manage its own interlocking, but separate control units are required on each working machine, increasing system complexity and cost
Solution Approach 1:
The patent extracts the display and operation functions for interlocking control from the working machines and relocates them to the work vehicle. The working machines retain their interlocking capability but the control interface is removed from them and consolidated on the work vehicle. This reduces the number of control units needed while maintaining reliable interlocking control through the centralized system on the work vehicle.

AI summary
The present describes a work vehicle where an operator can, on the work vehicle side, confirm which working machine is engaged and set which working machine to engage. A tractor, to which a working machine can be mounted, is provided with: a liquid crystal panel selectably displaying an engageable working machine mounted and displaying the currently engaged working machine so as to be identifiable; an operation unit (encoder dial, enter button, and command buttons) for carrying out selection and determination operations for the working machine displayed on the liquid crystal panel; and a control device that, when a determination operation is carried out by the operation unit for a desired working machine, disengages the currently engaged working machine, and configures the working machine for which the determination operation has been carried out to be engaged.
