Abstract

Disclosed herein are multiple sensor instruments for simultaneously or near simultaneously measuring two or more soil properties in situ. Also disclosed herein are controllers capable of communicating with the multiple sensor instruments and capable of determining one or more indirectly assessed soil properties based on the properties directly measured by the sensors. Also disclosed herein are instrumented systems combining the sensors and controller with one or more work tools which may be operationally controlled by the controller based on the directly measured or indirectly assessed soil properties, and methods for controlling a work operation using the same. Such systems may be further configured to communicate with an external data source, containing data that may be used along with the directly measured or indirectly assessed properties in controlling the work operation.

Dependent claims

A method for controlling one or more operations of a work machine in a work site, comprising:

generating a first sensor signal and a second sensor signal representative of a first soil characteristic at a work location and a second soil characteristic at the work location, respectively;
calculating a soil moisture content from the first soil characteristic and the second soil characteristic, and calculating a soil texture value from the first soil characteristic and the second soil characteristic;
estimating one or more further soil characteristics based at least on the soil moisture content and the soil texture value;
generating respective values for one or more operational settings based on at least one of the first soil characteristic, the second soil characteristic, and the one or more further soil characteristics;
and
controlling at least one operation of the work machine based on the generated one or more operational settings relative to current actual values for the one or more operational settings.
