Method for starting an internal combustion engine of a hybrid vehicle, comprising a first powertrain which has an internal combustion engine , a first electric machine and a gearbox mechanism , it being possible for the first electric machine to be coupled to the internal combustion engine via a disconnect clutch and to a first and/or second drive axle via a drive clutch , of which the slip is controllable, a second powertrain comprising a second electric machine which can be coupled to the first and/or second drive axle, it being possible for a drive torque to be provided via the first and second electric motors , characterized by the steps of: from a first time (tv), operating the first electric machine and actuating the drive clutch such that a torque of the first electric machine which acts via the first powertrain is reduced by a torque value (R), and operating the second electric machine such that a torque of the second electric machine which acts via the second drive train is correspondingly increased by the torque value (R), from a second time (t0), operating the drive clutch so that the speed of the first electric machine is increased using the torque value (R), and, from a third time (t1), at least partly closing the disconnect clutch such that the speed of the internal combustion engine is thereby increased until a start criterion is reached so that the internal combustion engine supports a starting process itself. a first powertrain which has an internal combustion engine , a first electric machine and a gearbox mechanism , it being possible for the first electric machine to be coupled to the internal combustion engine via a disconnect clutch and to a first and/or second drive axle via a drive clutch , of which the slip is controllable, a second powertrain comprising a second electric machine which can be coupled to the first and/or second drive axle, it being possible for a drive torque to be provided via the first and second electric motors , characterized by the steps of: from a first time (tv), operating the first electric machine and actuating the drive clutch such that a torque of the first electric machine which acts via the first powertrain is reduced by a torque value (R), and operating the second electric machine such that a torque of the second electric machine which acts via the second drive train is correspondingly increased by the torque value (R), from a second time (t0), operating the drive clutch so that the speed of the first electric machine is increased using the torque value (R), and, from a third time (t1), at least partly closing the disconnect clutch such that the speed of the internal combustion engine is thereby increased until a start criterion is reached so that the internal combustion engine supports a starting process itself. from a first time (tv), operating the first electric machine and actuating the drive clutch such that a torque of the first electric machine which acts via the first powertrain is reduced by a torque value (R), and operating the second electric machine such that a torque of the second electric machine which acts via the second drive train is correspondingly increased by the torque value (R), from a second time (t0), operating the drive clutch so that the speed of the first electric machine is increased using the torque value (R), and, from a third time (t1), at least partly closing the disconnect clutch such that the speed of the internal combustion engine is thereby increased until a start criterion is reached so that the internal combustion engine supports a starting process itself. <EOS>
