The invention relates to a method for operating an automatic transmission of a hybrid vehicle having a traction motor, on which a drag torque (18) is reserved, starting from a maximum available electrical power for driving the traction motor, and having an internal combustion engine, according to the invention, a characteristic curve cluster (10) having a respective curve (12) for a respective gear of an automatic transmission of the hybrid vehicle is constructed, and the characteristic curve cluster (10) is adapted as a function of the drag torque (18) to be reserved in such a way that each curve (12) is reduced with the drag torque (18) to be reserved, and a switching logic is specified, in which each curve (12) is reduced with the drag torque (18) to be reserved. A respective shift point (14) for shifting the automatic transmission is defined at the intersection of the curves (12) of the adjacent gears of the adapted characteristic curve cluster (10), at which the automatic transmission is shifted by means of a shift logic.
