The invention relates to a method for the open-loop and/or closed-loop control of a powertrain (1) of a motor vehicle, wherein the powertrain (1) has at least one internal combustion engine (2), at least one automatic transmission (3), in particular an automated manual transmission (3a), and at least one clutch (4) effectively arranged between the internal combustion engine and the automatic transmission. At least one control unit (5), in particular a transmission control unit (5b) and/or an engine control unit (5a), is provided, wherein with the help of the control unit (5), the clutch (4) is opened or closed depending on defined operating conditions during a journey of the motor vehicle. If the clutch (4) is closed, the internal combustion engine (2) is effectively coupled to the automatic transmission (3) and if the clutch (4) is open, the internal combustion engine (2) is effectively decoupled from the automatic transmission (3). If the clutch (4) is open, the motor vehicle can be operated in a rolling mode when the internal combustion engine (2) is running, or if the clutch (4) is open, the motor vehicle can be operated in a freewheel mode when the internal combustion engine (2) is turned off, and, in the rolling mode or freewheel mode, the clutch (4) is closed if the brake pedal or the drive pedal is actuated. The powertrain is flexibly and energy- and cost-efficiently designed because at the end of the brake pedal actuation, the clutch (4) is opened and a rolling mode of the motor vehicle is then effected, wherein if the internal combustion engine (2) was previously turned off, the internal combustion engine (2) is started and operated in neutral, or if the internal combustion engine (2) was already running, it is then operated in neutral.
