Electrically operable axle drive train, method for operating an electrically operable axle drive train, computer program product and control unit

A method for operating an electrically operable axle drive train for a motor vehicle, wherein the motor vehicle includes a first vehicle axle with a first electric machine configured to drive a first vehicle wheel of the first vehicle axle and a second electric machine configured to drive a second vehicle wheel of the first vehicle axle, a steering system configured to steer the motor vehicle, and a control unit configured to effect actuation of the steering system, the method comprising:

• monitoring a function of the first and second electric machines;
• identifying a malfunction in one of the first and second electric machines, based on detecting at least one of a lower speed or a lower torque being applied to one of the vehicle wheels than to the other vehicle wheel, wherein the at least one of the lower speed or the lower torque generates a resulting torque acting on the motor vehicle;
• calculating, via the control unit, a steering position of the steering system that counteracts the resulting torque;
• and
• actuating the steering system into the calculated steering position that counteracts the resulting torque.

A control unit configured to control an electrically operable axle drive train for a motor vehicle, the control unit comprising a processor and a non-transitory memory containing a computer program code, wherein the non-transitory memory and the computer program code are configured, with the processor, to:

• monitor a function of a first electric machine and a second electric machine in an axle drive train;
• identify a malfunction in one of the first and second electric machines based on detecting at least one of a lower speed or a lower torque being applied to a vehicle wheel on a first axle of the axle drive train than a further vehicle wheel on the first axle, wherein the at least one of the lower speed or the lower torque generates a resulting torque acting on the motor vehicle;
• calculate, via the control unit, a steering position of a steering system of the axle drive train that counteracts the resulting torque;
• and
• actuate the steering system into the calculated steering position that counteracts the resulting torque.
