Off-board Control for Power Machines via CAN Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power machine control systems are limited by the need for on-board operation, which can be impractical in environments with limited visibility or space, such as construction sites, where off-board control capabilities are necessary for safe and efficient operation.
Innovation Solution
A receiver system is integrated into the power machine to receive operating commands from an off-board control unit, utilizing a controller area network (CAN) to transmit and execute commands for controlling machine functions, allowing remote operation through a plug-and-play connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-board control is used, then the control system is simple and reliable, but the operator cannot operate safely in environments with limited visibility or space
Solution Approach 1:
The patent introduces an off-board control unit as an intermediary device that transmits control signals to the power machine through a receiver. This mediator allows the operator to control the machine from a remote location with better visibility and safety, while the machine's existing control system remains intact and reliable.
2Ease of operation
If off-board control is implemented, then operability in constrained environments is improved, but the control system complexity increases
Solution Approach 1:
The off-board control unit is designed to be universally compatible with existing power machine control systems through standardized communication protocols and interfaces. This multi-functionality allows the same control unit to work with different machine types without requiring custom integration, thereby limiting the increase in system complexity.
3Adaptability or versatility
If a custom off-board control system is developed, then specific operational requirements are met, but manufacturing cost and complexity increase
Solution Approach 1:
The control system is segmented into independent modular components: an off-board control unit, a receiver module, and integration with existing machine controllers. This segmentation allows each component to be manufactured separately using standard production processes, reducing overall manufacturing cost and complexity while maintaining operational flexibility.

AI summary
"Off-board" operating control (150) for a power machine or vehicle (100) is described. The "off-board" operating control includes a receiver unit that is configured to receive operating commands transmitted from an "off-board" control unit. The receiver (154) sends commands from the "off-board" control unit to a control component through a controller area network "on-board" the power machine or vehicle. In illustrated embodiment, the receiver unit is coupled to the controller area network through a connector, which plugs into an "off-board" controls module of the controller area network for plug and play operations.
