Abstract (en)
[origin: WO2018007088A1] A method for operating a motor vehicle having a drive assembly (1), having a transmission (2) and having a drive output (3), wherein the transmission (2) is formed as an automatic shift transmission, is connected between the drive output (3) and the drive assembly (1), and has multiple shift elements (4), wherein, to execute a gear change in the transmission (2), at least one previously closed shift element (4) is opened, and at least one previously open shift element (4) is closed. When, proceeding from overrun operation of the motor vehicle, a downshift from a current gear to a target gear is executed in the transmission (2), a braking torque is applied to the drive output (3) by means of a vehicle brake (5), which braking torque is dependent on the overrun torque prevailing at the drive output (3) before the execution of the downshift.
