    摘要: The hybrid drive train has an internal combustion engine connected to a first input shaft via a first clutch and connected to a second input shaft via a second clutch. An electric machine is connected to the second input shaft. The first input shaft is coupled to an output shaft via a first gear, and the second input shaft is coupled to the output shaft via two second gears. In the method for operating the hybrid, the first gear is engaged and torque is applied by the engine. To change, one of the second gears is engaged, engine torque is reduced by slipping the clutch while electric machine torque is increased. To change again, electric machine torque is reduced to zero, the other second gear is engaged while engine torque transmitted via the first clutch is increased by reducing slipping of the first clutch.
