Claim 0:
1. A method for operating a motor vehicle, which has multiple drive wheels and multiple drive machines, each of the drive machines being an electric machine, being allocated to a respective drive wheel of the drive wheels, the method comprising the following steps:
acquiring a total setpoint drive torque;
acquiring a current vehicle driving speed and a current steering angle;
determining respective wheel speeds of the drive wheels over a roadway as a function of the current vehicle driving speed, the current steering angle, and a known chassis geometry of the motor vehicle;
determining a setpoint wheel speed for each of the drive wheels as a function of the determined wheel speeds and the current steering angle in such a way that a radius of an actual curve path is set that is smaller than a radius of a setpoint curve path specified by a maximally possible steering angle, in the process of which multiple drive wheels produce slip;
distributing the total setpoint drive torque to all drive wheels as a function of the wheel loads in order to influence the setpoint speed at the respective drive wheel; and
actuating each of the drive machines in order to adjust the setpoint wheel speed and the respective torque at the respective drive wheel.
