Traction aid function for vehicles having multiple driven axles

A method for transferring a drive torque from wheels having a low traction to wheels having a higher traction for a vehicle having multiple driven axles, in which several but not all driven wheels are equipped with a rotational speed sensor, the method comprising:

• measuring, with a cardan shaft sensor, a rotational speed of a cardan shaft;
• measuring, with a rotational speed sensor, a wheel rotational speed of at least one wheel equipped with the rotational speed sensor;
• comparing, with a control unit, the rotational speed of the cardan shaft to the wheel rotational speed of the at least one wheel equipped with the rotational speed sensor;
• and
• upon determining that the deviation between the cardan shaft rotational speed and the wheel rotational speed is too high, automatically triggering a braking process, with the control unit, at at least one wheel that does not have a rotational speed sensor,
• wherein in the case of a vehicle which has at least two rear axles and in which at least one wheel at each of the multiple rear axles does not have a rotational speed sensor, all wheels of the associated rear axles are braked so that the drive torque is transferred from these wheels to the front wheels.
