A method of operating a drivetrain of a motor vehicle. The drivetrain comprises a drive aggregate formed as a hybrid drive with a combustion engine and an electric machine, and a transmission connected between the drive aggregate and a drive output. The drivetrain also comprises a pressure reservoir system with at least one pressure reservoir and at least one pressure generator by the combustion engine in order to fill the pressure reservoir. A pressure in the pressure reservoir of the pressure reservoir system is measured and a value of the actual pressure, in the pressure reservoir system, is compared with at least one threshold value. When the actual pressure value is higher than a threshold value, stopping of the combustion engine is permitted, whereas if the actual pressure value is lower than the threshold value, stopping of the combustion engine is not permitted.
