The invention relates to a method for controlling a hybrid drive train (1) of a hybrid motor vehicle, the hybrid drive train (1) having a dual clutch transmission (2) with two partial transmissions (3, 4), the transmission input shafts (5, 6) of which can be coupled in each case by means of friction clutches (7, 8) to a first drive unit (9) in a drive-effective manner, wherein one of the two transmission input shafts (5, 6) is coupled or coupleable to the second drive unit (10) in a drive-effective manner, characterized in that in the event of a malfunction of the second drive unit (10) during a synchronization process for preparing a gear shift, the friction clutch (7, 8) associated with the partial transmission (3, 4) slips at least momentarily, and the friction clutch (7, 8) slips at least momentarily in the event of a malfunction of the second drive unit (10). According to the invention, the partial transmission (3, 4) and the second drive unit (10) are set via the first drive unit (9) to a synchronous rotational speed, the transmission input shaft (5, 6) of which is or can be coupled to the second drive unit (10) in a drive-effective manner.

    一种用于控制混合动力机动车的混动动力总成(1)的方法,其中所述混动动力总成(1)具有带有两个子变速器(3、4)的双离合变速器(2),两个子变速器的变速器输入轴(5、6)能够分别借助于摩擦离合器(7、8)与第一驱动单元(9)以驱动有效的方式耦联,其中两个变速器输入轴(5、6)之一与第二驱动单元(10)以驱动有效的方式耦联或可耦联,其特征在于,在用于准备换挡的同步过程中在第二驱动单元(10)发生故障的情况下,与子变速器(3、4)相关联的摩擦离合器(7、8)至少短暂地打滑,使得所述子变速器(3、4)和所述第二驱动单元(10)经由所述第一驱动单元(9)设定为同步转速,所述子变速器的变速器输入轴(5、6)与所述第二驱动单元(10)以驱动有效的方式耦联或可耦联。
