Method and device for predictive control of agricultural vehicle systems

摘要

A method for controlling an agricultural vehicle system when moving along a course of travel over a field
providing a field model correlating a field characteristic, e.g. a farmland condition such as farmland slope, or a crop condition such as crop density or moisture, to a specific location in the field,from the field model and at least one previously obtained value for the field characteristic, predicting a value for the field characteristic in front of the agricultural vehicle system thus obtaining an anticipated field characteristic, and;controlling the agricultural vehicle system at least partly in response to the anticipated field characteristic.

1. A method for controlling an agricultural vehicle system when moving along a course of travel over a field, the method comprising:
providing a field model correlating a field characteristic to a specific location in the field, from the field model and at least one previously obtained value for the field characteristic, predicting a value for the field characteristic in front of the agricultural vehicle system thus obtaining an anticipated field characteristic, and controlling the agricultural vehicle system at least partly in response to the anticipated field characteristic, wherein providing the field model correlating a field characteristic to a specific location in the field includes assuming that field characteristic varies in a continuous manner by taking into account first and second order derivatives of the field model variables; and wherein the previously obtained value for the field characteristic is from a location different than the location in front of the machine for which the value of the field characteristic is predicted.
