FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery industry, in particular to a method of automatic setting of at least one of the plurality of working bodies used in the process of harvesting, of a self-propelled harvesting machine. The method comprises the step of performing initial modelling of the harvesting process using at least one three-dimensional graphic characteristic (KFAi, KFRi) based on a database typical for the harvesting process to be performed. Then based on the initial modelling the initial operating point (APi) of at least one working body is determined. Then at least one three-dimensional graphic characteristic (KFA(n), KFR(n)) is adapted, based on the current data obtained by the measurement, which influence on the harvesting process, and a new operating point (AP (n)) of at least one working body is determined, depending on adaptation of the three-dimensional graphic characteristic (KFA(n), KFR(n)). Then iterative approximation to the new operating point (AP(n+1)) is performed. After the step (AS) of approximation to the new operating point (AP(n)) the time of achieving the quasi-steady behaviour of the machine is maintained, and the obtained values of setting parameters of working bodies are left depending on the result of validity check of the three-dimensional graphic characteristic (KFA(n), KFR(n)) or returned to their values corresponding to the previous operating point (AP(n-1)).

EFFECT: method provides a flexible response to changing boundary conditions during the harvesting process.
