The invention relates to an electrically operable axle drive train (1) for a motor vehicle (2), comprising a first vehicle axle (3) and a steering system (8) for steering the motor vehicle (2) and a control unit (9) designed to actuate the steering system (8), the first vehicle axle (3) has a first electric machine (4) for driving a first vehicle wheel (5) of the first vehicle axle (3) and at least one second electric machine (6) for driving a second vehicle wheel (7) of the first vehicle axle (3), in the event of a failure of one of the electric machines (4, 6) of the electrically operable axle drive (1), the first vehicle wheel (5) is driven by the first electric machine (4), and the second vehicle wheel (7) is driven by the at least one second electric machine (6). Wherein the speed and/or torque applied to one of the vehicle wheels (5) is lower than the speed and/or torque applied to the other vehicle wheel (7), a resulting torque (12) acting on the motor vehicle (2) is generated and compensated by a steering position (13) of the steering system (8) that counteracts the torque (12) and is actuated by the control unit (9).

    本发明涉及一种用于机动车辆(2)的可电动操作的车轴传动系(1),该可电动操作的车轴传动系包括第一车辆车轴(3)以及用于使机动车辆(2)转向的转向系统(8)和设计成使转向系统(8)被致动的控制单元(9),该第一车辆车轴具有用于驱动第一车辆车轴(3)的第一车辆车轮(5)的第一电机(4)以及用于驱动第一车辆车轴(3)的第二车辆车轮(7)的至少一个第二电机(6),其中,在可电动操作的车轴传动系(1)的电机(4、6)中的一者发生故障的情况下,其中施加至车辆车轮中的一个车辆车轮(5)的速度和/或扭矩比施加至另一个车辆车轮(7)的速度和/或扭矩更低,则会产生作用在机动车辆(2)上的由此得到的扭矩(12)并且该扭矩通过转向系统(8)的抵消该扭矩(12)并由控制单元(9)致动的转向位置(13)来补偿。
