Abstract
One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.
Claims18
An agricultural work machine comprising:
- a communication system that receives an information map that includes values of a crop state corresponding to different geographic locations in a field;
- a geographic position sensor that detects a geographic location of the agricultural work machine;
- an in-situ sensor that detects a value of an agricultural characteristic corresponding to the geographic location;
- a predictive model generator that generates a predictive agricultural model that models a relationship between crop state and the agricultural characteristic based on a value of crop state in the information map at the geographic location and the value of the agricultural characteristic, detected by the in-situ sensor, corresponding to the geographic location;
- a predictive map generator that generates a functional predictive agricultural map of the field that maps predictive control values to the different geographic locations in the field based on the values of crop state in the information map and based on the predictive agricultural model;
- a controllable subsystem;
- and
- a control system that generates a control signal to control the controllable subsystem based on the geographic position of the agricultural work machine and based on the control values in the functional predictive agricultural map.
A computer implemented method of controlling an agricultural work machine comprising:
- obtaining an information map that includes values of a crop state characteristic corresponding to different geographic locations in a field;
- detecting a geographic location of the agricultural work machine;
- detecting, with an in-situ sensor, a value of an agricultural characteristic corresponding to a geographic location;
- generating a predictive agricultural model that models a relationship between the crop state characteristic and the agricultural characteristic based on a value of the crop state characteristic in the information map at the geographic location and the detected value of the agricultural characteristic corresponding to the geographic location;
- generating a functional predictive agricultural map of field that maps predictive control values to the different geographic locations in the field based on the values of the crop state characteristic in the information map and based on the predictive agricultural model;
- and
- controlling a controllable subsystem based on the geographic position of the agricultural work machine and based on the control values the functional predictive agricultural map.
