Abstract
One or more information maps are obtained by an agricultural system. The one or more information maps map one or more characteristic values at different geographic locations in a worksite. An in-situ sensor detects a material dynamics characteristic value as a mobile machine operates at the worksite. A predictive map generator generates a predictive map that predicts a predictive material dynamics characteristic value at different geographic locations in the worksite based on a relationship between the values in the one or more information maps and the material dynamics characteristic value detected by the in-situ sensor. The predictive map can be output and used in automated machine control.
Claims17
An agricultural system comprising:
- a communication system configured to receive an information map that includes values of a characteristic corresponding to different geographic locations in a worksite;
- a geographic position sensor configured to detect a geographic location of a mobile machine;
- an in-situ sensor configured to detect a value of a material movement characteristic, of material in an on-board material receptacle of the mobile machine, corresponding to the geographic location;
- one or more processors;
- and
- memory storing instructions executable by the one or more processors that, when executed by the one or more processors, configure the one or more processors to:
- generate a predictive material movement model that models a relationship between the characteristic and the material movement characteristic based on a value of the characteristic in the information map corresponding to the geographic location and the value of the material movement characteristic detected by the in-situ sensor corresponding to the geographic location;
- generate a functional predictive material movement map of the worksite that maps predictive values of the material movement characteristic to the different geographic locations in the worksite based on the values of the characteristic in the information map and based on the predictive material movement model;
- and
- control one or more controllable subsystems of the mobile machine based on the functional predictive material movement map, wherein the one or more controllable subsystems include one or more of:
- a steering subsystem;
- a propulsion subsystem;
- and a material transfer subsystem.
