Working Vehicle Controller Attachment Identification Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for determining the position of attachments on working vehicles are inefficient due to unnecessary processing load and repeated identification of attached attachments, leading to potential hindrances in smooth operation.
Innovation Solution
A working vehicle equipped with a hitch, a receiver for wireless signals from transmitters on attachments, and a controller that stores identification information for attached attachments, allowing for efficient operation without repeated identification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the identification module determines the position of an attachment every time a wireless signal is received, then the attachment position can be tracked in real-time, but the processing load on the identification module increases needlessly
Solution Approach 1:
The system performs attachment identification only when necessary (when attachment/detachment is detected), rather than continuously processing every wireless signal. The controller monitors operational states and triggers identification processes selectively, reducing unnecessary processing while maintaining accurate tracking when events occur.
Solution Approach 2:
The system uses periodic wireless signals from transmitters on attachments to detect attachment status, but processes these signals only at relevant intervals (when attachment state changes are detected) rather than continuously analyzing every signal reception, thereby reducing processing load while maintaining detection capability.
2Loss of information
If the identification module repeatedly identifies the attached attachment every time a signal is received, then the attachment information is continuously updated, but the smooth operation of the working vehicle is hindered
Solution Approach 1:
The system pre-identifies attachments when they are first attached to the working vehicle and stores this information. Subsequent wireless signal receptions during operation do not trigger repeated identification processes, allowing smooth continuous operation while maintaining attachment information availability.
Solution Approach 2:
The identification function is extracted and performed only at specific moments (when attachment state changes occur), rather than being continuously executed. This separates the identification process from the ongoing operational signals, preventing interference with smooth vehicle operation.
3Adaptability or versatility
If the controller adjusts the operation of the working vehicle every time the identification module identifies an attachment, then the vehicle can adapt to different attachments, but inefficiency is caused due to repeated adjustments
Solution Approach 1:
The controller adjusts vehicle operations in advance when an attachment is first identified and attached. Once the adjustment is made, subsequent signal receptions during operation do not trigger repeated adjustments, maintaining adaptability while improving operational efficiency through the initial setup.

AI summary
A controller is configured or programmed to cause a first memory to store, for a period of time, piece(s) of identification information included in wireless signal(s) transmitted from transmitter(s) in or on attachment(s) and received by a receiver in or on a working vehicle, when one of the attachment(s) is attached to a hitch, select a piece of identification information of the attachment attached to the hitch from the piece(s) of identification information stored in the first memory and start a predetermined process according to the selected piece of identification information, and even if the receiver receives wireless signal(s) before the attachment is allowed to be detached from the hitch, continue to perform the predetermined process without performing selection of a piece of identification information again.
