A method is provided for starting a piston engine of a hybrid drive in an electric travel state. The hybrid drive includes at least the piston engine, an electric motor, a transmission, and a clutch situated between the piston engine and the electric motor. A converter lockup clutch, which is switchable into a slip state, is also provided. A slip is set at the converter lockup clutch, and a speed of the electric motor is then increased. The speed and the torque either do not change or only change in a predefined range at the output side of the converter lockup clutch. The clutch is closed to transmit a torque pulse, so that a first top dead center of the piston of the piston engine may be overcome. A predefined slip is then set at the clutch.
