A method for operating an automatic transmission of a hybrid vehicle which has an electric traction machine and an internal combustion engine. A drag torque is provided at the electric traction machine. On the basis of a maximally available electric power for driving the electric traction machine, a characteristic map having respective curves for respective gears of the automatic transmission of the hybrid vehicle is created. The characteristic map is adjusted according to the drag torque to be provided by each curve being reduced by the drag torque to be provided. A shifting logic is specified in which respective shifting points for shifting the automatic transmission are defined at intersections of the curves of adjacent gears of the adjusted characteristic map, wherein the automatic transmission is shifted on the basis of the shifting logic in the respective shifting points.
