A method for operating a drive train of a motor vehicle for a reversing operation for changing from a forward gear to a reverse gear or vice versa when the motor vehicle is rolling at a speed less than a limit value, and in which a first shift element of the transmission is disengaged and a second shift element of the transmission is engaged, the method including receiving a target torque profile for a transmission output shaft for the reversing operation. The method further includes determining, based on the target torque profile for the transmission output shaft, target torque profiles for the first and second shift elements and the propulsion unit. Additionally, the method includes activating the first and second shift elements and the propulsion unit based on the respective target torque profile such that an actual torque profile follows the target torque profile for the transmission output shaft.
