Problems solved by technology

Accurately measuring efficiency without inserting extra steps when moving soil is difficult
For example, weighing the contents of the actuator's bucket could insert an extra step that could make the entire earthmoving process inefficient
The process used to determine the amount of contents in a bucket without physical contact with the bucket may not accurately estimate the volume of the contents

Abstract

The invention relates to controlling of a work machine based on sensed variables. The mobile work machine includes a frame and a ground engaging element movably supported by the frame and driven by anengine to drive movement of the mobile work machine. The mobile work machine includes a container movably supported by the frame, the container configured to receive contents and an actuator configured to controllably drive movement of the container relative to the frame. The mobile work machine includes a control system configured to generate an actuator control signal, indicative of a commandedmovement of the actuator, and provide the actuator control signal to the actuator to control the actuator to perform the commanded movement and a content density determination system, communicativelycoupled to the control system, configured to determine a density of the contents of the container.

Description

technical field [0001] The present disclosure generally relates to devices used in earth moving operations. More specifically, but without limitation, the present disclosure relates to determining the volume and / or weight of the contents of a container of a work machine. Background technique [0002] Operating work machines such as excavators or shovels is a highly individual skill. Efficiency—for example, the earthmoving a work machine moves over a period of time—is one way to measure at least part of that skill. Efficiency is also a way of measuring the performance of a particular machine. Accurately measuring efficiency without inserting extra steps when moving soil is difficult. For example, weighing the contents of the actuator's bucket could insert an extra step that could render the entire earthmoving process inefficient. Processes for determining the amount of content in a bucket without physical contact with the bucket may not accurately estimate the volume of t...
