Methods and systems of the present invention are provided for performing proxy control functions in an environment including one or more work machines. Such methods and systems may leverage one or more gateways to serve as a proxy for one or more distinct modules. A gateway, located in a work machine, may be programmed with proxy logic that performs functions associated with certain modules used in a work machine environment. The gateway may monitor a data link and retrieve broadcasted messages. The broadcasted messages may include source and/or destination module address identifiers. The gateway may retrieve messages from the data link based on a determination that the message is destined for a module for which the gateway serves as a proxy. The gateway may route a retrieved message, using a mapping structure, to the appropriate proxy logic that performs functions associated with the destination module.

Methods and systems are provided for performing protocol conversions in an environment including a work machine having one or more modules coupled to one or more data links. Such methods and systems may leverage one or more gateways to perform tunneling, translating, and bridging operations. Tunneling processes may include receiving a message from a source module in a first protocol, encapsulating the message within transmission units of a second protocol, and transmitting the encapsulated message via the second protocol. Translating processes may include receiving, by the gateway, a message in a first data link protocol including a parameter identifier. The gateway may match the parameter identifier with a parameter identifier included in a translation table and scale associated parameter data using a scale factor corresponding to a second data link protocol. The gateway may then provide the scaled parameter data to a module using the second data link protocol.

Systems and methods for performing protocol conversions in a machine

A method and system are provided to perform a process of managing communications in an environment including a mobile work machine having one or more on-board data links connected to one or more on-board modules and a gateway and including one or more off-board data links connected to one or more off-board systems and the gateway. The process is performed by the gateway and includes receiving a request generated by a source device and transmitted on a first data link. In one embodiment, the first data link may be either one of the on-board data links and one of the off-board data links. Based on the request, the gateway selectively executes a server application that performs a server process. Further, the gateway identifies a destination device associated with the request, configures the request to a format compatible with the destination device, and provides the formatted request to the destination device. Additionally, the gateway receives a response to the formatted request generated by the destination device, configures the response to a format compatible with the first data link, and sends the response to a target device over the first data link.

Systems and methods for providing server operations in a work machine

The present invention is a method and apparatus for training an operator of an earthworking machine having an implement control system. The method and apparatus includes switching from control by the implement control system to control by the operator, monitoring operator control commands, and comparing the operator control commands to control commands of the implement control system. The method and apparatus also includes communicating the comparison to the operator.

Method and apparatus for using a control system of an earthworking

The present invention provides a method for selecting a steering method for an earthmoving machine having a blade and first and second tracks. One embodiment of the present invention includes selecting a steering method based on the position error of the machine. In another embodiment of the present invention the steering method is selected based on the elevation of the work implement, and the position error.
