The invention relates to a method for operating a drive axle (1) of a motor vehicle (3), a control unit (2) for carrying out the method, a drive axle and a motor vehicle (3). In the method, a driving state variable characterizing a current driving situation is detected. A coupling probability value K is determined on the basis of the driving state variable, and the rotational speed of the transmission output element (16) is adapted to the wheel drive shaft rotational speed (15) by means of the traction motor (5) if the coupling probability value K is greater than a limit value G. The rotational speed adaptation is carried out predictively regardless of whether a coupling process, in which the transmission output element (16) and the wheel drive shaft (15) are coupled to each other in a rotationally fixed manner, is subsequently started.

    本发明涉及一种用于运行机动车(3)的驱动桥(1)的方法、用于实施该方法的控制单元(2)、驱动桥和机动车(3)。在该方法中,检测表征当前行驶状况的行驶状态参量。基于行驶状态参量确定耦联概率值K,并且如果耦联概率值K大于限界值G,则借助牵引电机(5)使变速器输出元件(16)的转速匹配于车轮驱动轴转速(15)。该转速匹配预测性地进行,即与耦联过程是否随后开始无关,在所述耦联过程中变速器输出元件(16)和车轮驱动轴(15)彼此不可相对转动地耦联。
