1. A method for controlling crop material separation process in the combine harvester (1) comprising a separation device (4, 18) from which crop material is given to the cleaning device (5) comprising at least one reducible vibrated sieve (15 , 16) with cells controlled size for separation is in the crop material grains from non-cereal fractions and the fan (14) by means of which the at least one sieve (15, 16) the cleaning unit (5) is fed to the air flow for loosening located thereon to remove mass, wherein the set of substantially three different phases (F, S, W) loosening otlichayuschiysyatem that the method comprises the following steps when loosening the crop material: - measure the actual curves (33A, 34A), separation of the crop material on the cleaning unit width (5) locations spaced apart in the direction (FR) of transportation, - estimate the measured actual curves (33A, 34A) of separation, - recognizing existing in the direction (FR) transporting phase (F, S, W) loosening by comparing measured actual curves (33A 34A) separation of a u dependence on the detected phase (F, S, W) the disintegration is carried out at least one action, which leads to the optimization of disintegration on at least one portion of the cleaning unit (5) .2. A method according to claim 1, characterized in that by means of at least one action act on one of the units: the separating device (4, 18), the clearing device (5) or the fan (14) .3. A method according to claim 2, characterized in that depending on the detected phase (F, S, W) loosening change the fan speed by uchastkam.4. A method according to claim 3, Exc1. Способ управления процессом сепарации убранной массы в зерноуборочном комбайне (1), содержащем сепарирующее устройство (4, 18), от которого убранная масса выдается на очистное устройство (5), содержащее, по меньшей мере, одно приводимое в колебательное движение решето (15, 16) с регулируемым размером ячеек для отделения находящегося в убранной массе зерна от незерновых ф
