FIELD: transport.
SUBSTANCE: invention relates to automotive industry, namely to automatic gearboxes. Proposed method consists in that on shifting from one gear to target gear, drive engine torque reduction, clutch torque and disengagement in automatic gearbox are coordinated. Engine torque and clutch torque are reduced so that they coincide in time. Clutch reaching slipping torque, engine torque is reduced. With current gear in, engine torque is transferred via slipping clutch to gearbox input shaft and engine torque is increased to target rpm. On disengaging clutch, previous gear is disengaged and engine torque is transferred via clutch to automatic gearbox input shaft.
EFFECT: reduced time interval of reaching maximum engine torque in gearshifting.
