FIELD OF THE DESCRIPTION

The present description generally relates to mobile work machines. More specifically, but not by limitation, the present description relates to a machine performance detection and control system for a mobile work machine based on topological analysis of sensor signals.

BACKGROUND

There are many different types of mobile work machines. Those mobile work machines can include agricultural machines, construction machines, turf management machines, forestry machines, among others. Many of these pieces of mobile equipment have subsystems that are controlled by an operator and/or automatically in performing operations. Agricultural examples include machines such as a combine or harvester, a baler, a row unit planter, an air seeder, a sprayer, to name a few. Some construction examples include machines such as an articulated dump truck, a wheel loader, a grader, an excavator, a scraper, an asphalt milling machine, to name a few. Construction machines are often tasked with transporting material across a worksite, or into or out of a worksite, in accordance with a worksite operation. Different worksite operations may include moving material from one location to another or leveling a worksite, etc.

The subsystems of a mobile work machine can have a variety of machine components or parts. Often, a number of these components are interchangeable or replaceable. Examples of replaceable components include parts such as wheels, tires, tracks, bearings, valves, batteries, or any of a wide variety of other types of parts that wear or deteriorate with usage over time. Many of these parts have a predefined service life or expected lifecycle after which the parts are to be serviced or replaced.

The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.

SUMMARY

A mobile work machine includes a sensor configured to generate a sensor signal indicative of operation of the mobile work machine, a machine performance detection system configured to receive the sensor signal, generate a topological representation of the sensor signal, and determine a machine performance characteristic based on the topological representation relative to a reference model, and a control system configured to generate a control signal to control the mobile work machine based on the machine performance characteristic.

This Summary is provided to introduce a selection of concepts in a simplified form that is further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to implementations that solve any or all disadvantages noted in the background.
