The invention relates to a method and a control device for operating a drive train of a vehicle, the drive train having a first electric machine with a first power electronics, a second electric machine with a second power electronics, and a transmission device connected between the electric machines and an output, the first electric machine and the second electric machine being operated in order to carry out a power shift, one of the electric machines is used as a main drive machine, and the other electric machine is used for traction support during the implementation of a power shift. When the actual temperature of at least one of the electric machines and/or the actual temperature of at least one of the power electronics is greater than a temperature limit value, and/or when the target current flowing through at least one of the electric machines and/or at least one of the power electronics in the power shift to be carried out is greater than a current limit value, the power shift to be carried out is carried out. The power shift to be carried out is adjusted in order to limit the temperature rise of the respective electric machine and/or of the respective power electronics.

    本发明涉及用于运行车辆的驱动系的方法和控制器,其中,驱动系具有配备了第一功率电子器件的第一电机、配备了第二功率电子器件的第二电机以及接到电机与输出部之间的传动装置,其中,为了实施动力换挡,运行第一电机和第二电机,使得其中一个电机被用作主驱动机,而其中另一电机在实施动力换挡期间被用于牵引力支持。当其中至少一个电机的实际温度和/或其中至少一个功率电子器件的实际温度大于温度边界值时,和/或当在要实施的动力换挡中流过其中至少一个电机和/或其中至少一个功率电子器件的目标电流大于电流边界值时,调整要实施的动力换挡,以便限制各自的电机和/或各自的功率电子器件的升温。
