The invention relates to a method for operating a drive train of a motor vehicle, wherein the drive train comprises at least one hybrid drive having an internal combustion engine and an electric motor, a transmission disposed between the hybrid drive and a power take-off, and a clutch disposed between the internal combustion engine and the electric motor, wherein, when only the electric motor is driving, the internal combustion engine can be started in that the clutch disposed between the internal combustion engine and the electric motor is closed. According to the invention, when the electric motor is operated in motor-braking mode in an exclusively electric motor drive mode, and a desired transition from motor-braking mode into traction mode is derived from a determined torque desired by the driver, the internal combustion engine is started, using the shift from braking to traction mode, in that the clutch disposed between the internal combustion engine and the electric motor is closed at least partially, such that said clutch transmits a torque required for starting the internal combustion engine. |
