FIELD: machine building.
SUBSTANCE: moment increment value is calculated, moment drop value is calculated, new calculation of moment estimative value is carried out, obtained new moment estimative value is compared to moment limit value. Moment increment value is calculated depending upon the difference between input and output elements rotation frequencies. Moment drop value is calculated depending upon moment estimative value. New calculation of moment estimative value is carried out on the base of the last calculated moment estimative value. Clutch is deactivated, when new calculated moment estimative value reduces below moment limit value.
EFFECT: safe and reliable deactivation of clutch.
