Title: Gateway Controller for Machine Modification
Brief Description of the Drawings: Figure 1 is a schematic view of the system layout of this disclosure. Figure 2 is a schematic view of the system communication process of this disclosure.
As shown in the attached illustrations and described below, a controller that allows aftermarket systems to interact with an OEM machine’s controls without the need to physically connect the aftermarket system to the existing machine electrical system, is disclosed.
A user of an off‐road vehicle or work vehicle (such as a construction or forestry work vehicle), or a 3rd party aftermarket company, may at times add equipment to or make vehicle modifications to an OEM vehicle. For example, a vehicle modification may include changes to a boom system or a winch system. Typically, this involves tapping into the vehicle’s electrical system. This includes splicing into the OEM wiring, adding components to trick the OEM systems, and adding messages to the OEM CAN bus. This approach can negatively impact the OEM machine’s electrical system.
The idea, as shown in Figures 1 and 2 and described in this disclosure, is to add a controller to act as a gateway between the OEM vehicle system and the added components of a 3rd party system.
Commands and information are sent from the aftermarket system to the gateway using predefined CAN messages. The gateway controller receives these messages and re‐broadcasts them ont...
