Map generation and control system

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.

  1. 1
    An agricultural work machine, comprising:a communication system that receives an information map that includes values of a first agricultural characteristic 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 a second agricultural characteristic indicative of a characteristic of processed material corresponding to the geographic location;a predictive model generator that generates a predictive agricultural model that models a relationship between the first agricultural characteristic and the second agricultural characteristic based on a value of the first agricultural characteristic in the information map at the geographic location and a value of the second agricultural characteristic sensed by the insitu sensor at the geographic location;and a predictive map generator that generates a functional predictive agricultural map of the field that maps predictive values of the second agricultural characteristic to the different geographic locations in the field based on the values of the first agricultural characteristic in the information map and based on the predictive agricultural model.
  2. 4
    The agricultural work machine of daim 1, wherein the in-situ sensor comprises:a loss sensor that senses, as the second agricultural characteristic, a characteristic indicative of crop loss from the agricultural work machine. Date Reçue/Date Received 2021-09-02
  3. 17
    A computer implemented method of generating a functional predictive agricultural map, comprising:receiving an information map, at an agricultural work machine, that indicates values of a first agricultural 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 second agricultural characteristic indicative of a characteristic of processed material corresponding to the geographic location;generating a predictive agricultural model that models a relationship between the first agricultural characteristic and the second agricultural characteristic;and controlling a predictive map generator to generate the functional predictive agricultural map of the field that maps predictive values of the second agricultural Date Reçue/Date Received 2021-09-02 characteristic to the different locations in the field based on the values of the first agricultural characteristic in the information map and the predictive agricultural model.
  4. 19
    An agricultural work machine, comprising:a communication system that receives an information map that includes values of a first agricultural characteristic 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 a second agricultural characteristic indicative of a characteristic of processed material corresponding to the geographic location;a predictive model generator that generates a predictive agricultural model that models a relationship between the first agricultural characteristic and the second agricultural characteristic based on a value of the first agricultural characteristic in the information map at the geographic location and a value of the second agricultural characteristic sensed by the in-situ sensor at the geographic location;and a predictive map generator that generates a functional predictive agricultural map of the field that maps predictive values of the second agricultural characteristic to the different geographic locations in the field based on the values of the first agricultural characteristic in the information map and based on the predictive agricultural model, the predictive map generator configuring the functional predictive agricultural map for a control system that generates control signals to control a controllable subsystem on the agricultural work machine based on the functional predictive agricultural map.
