The invention relates to a method for starting an internal combustion of a hybrid vehicle comprising a first powertrain (1) which comprises an internal combustion engine (2), a first electric machine (3), and a transmission (5). The first electric machine (3) can be coupled to the internal combustion engine (2) via a disconnect clutch (7) and to a first and/or second drive axle (4; 204) via a starting element (6). The hybrid vehicle also comprises a second powertrain (201) with a second electric machine (203) to which the first and/or second drive axle (4; 204) can be coupled, wherein a respective drive torque can be provided via the first and second electric machine (3, 203). The invention is characterized by the following steps: operating the first electric machine (3) and actuating the starting element (6) after a first point in time (tv) such that a first electric machine (3) torque acting via the first powertrain (1) is reduced by a torque value (R) and operating the second electric machine (203) such that a second electric machine (203) torque acting via the second powertrain (201) is increased by a value (R) in a corresponding manner; and operating the first electric machine (3) and at least partly closing the disconnect clutch (7) after a second point in time (t0) such that the rotational speed of the internal combustion engine (2) is increased until a starting criterion is reached such that the internal combustion engine (2) supports a starting process.
