1. A method for controlling a drive of a vehicle having a first axle with at least one mounted wheel, comprising:

  • setting by a driver a drive torque of the vehicle,driving the first axle with a first electric machine as a function of the drive torque,providing electrical energy with a second electric machine coupled to at least one combustion engine for driving the first axle with the first electric machine,driving a second axle having at least one mounted wheel with the at least one combustion engine that is coupled to the second electric machine in order to operate the second axle with both the at least one combustion engine and the second electric machine,computing, by taking into account the drive torque and machine parameters of at least the second electric machine, a target torque associated with the second electric machine and with the at least one combustion engine, andcontrolling the second electric machine and the at least one combustion engine in parallel to the associated target torque with identical magnitude, but reverse mathematical sign, while driving the first axle.
