The invention relates to a method and a control device for operating a drive train of a vehicle, comprising a first electric machine, a second electric machine and a transmission device, the electric machines being loaded or operated with the same torque and torque gradient during symmetrical operation of the electric machines, the electric machines being loaded or operated with the same torque and torque gradient during gear shifting in an asymmetrical operation of the electric machines in the transmission device. The electric machine is loaded or operated with different torques and/or torque gradients. According to the invention, if it is detected during the symmetric operation that a shift is to be carried out in the transmission in the manner of asymmetric operation of the electric machine, the symmetric operation is withdrawn before the shift is carried out in order to provide a pre-control operation, the electric machine, which is operated with a higher torque and/or torque gradient during the implementation of the shift, is operated with a limited torque and/or a limited torque gradient, in order to reduce the temperature of the electric machine and the temperature of the power electronics associated with the electric machine, which are operated with a higher torque and/or torque gradient during the implementation of the gear shift, by means of the preconditioning operation prior to the implementation of the gear shift.

    用于运行车辆的驱动系的方法和控制设备,驱动系具备第一电机、第二电机以及传动装置,其中,在电机对称运行中,电机以相同转矩和转矩梯度受负荷或运行,其中,在传动装置中以电机非对称运行的方式实施换挡期间,电机以不同转矩和/或转矩梯度受负荷或运行。如果在对称运行期间识别到:在传动装置中要以电机非对称运行的方式实施换挡,则在实施换挡之前退出对称运行以用于提供预调节运行,其中,在实施换挡期间以较高转矩和/或转矩梯度运行的那个电机以受限的转矩和/或受限的转矩梯度运行,以便经由预调节运行在实施换挡之前降低在实施换挡期间以较高转矩和/或转矩梯度运行的那个电机的温度以及与那个电机相配属的功率电子器件的温度。
