Abstract

A method includes ascertaining a first drive force and a second drive force for a first drive axle and a second drive axle of a vehicle, ascertaining a first slip value and a second slip value for the first drive axle and the second drive axle of the vehicle, determining a first slip measured value for the first drive axle from the first drive force and the first slip value and determining a second slip measured value for the second drive axle from the second drive force and the second slip value, determining a total torque that is to act altogether on the first drive axle and the second drive axle, and dividing the total torque into a first desired torque and a second desired torque in dependence upon the first slip measured value and the second slip measured value.
