Claim 0:
1. An antilock control method for a braking system of a vehicle, the antilock control method comprising the following steps upon input of a brake request signal (S1):
outputting a brake control signal (S2);
building up a brake pressure (pb) via a braking medium at a wheel brake of a vehicle wheel (St1, t0);
measuring a wheel speed (n) of the vehicle wheel to be braked (St3);
determining at least one of the following:
i) a wheel slip (s) of the wheel; and,
ii) wheel circumferential velocity (v2) of the vehicle wheel; and,

upon satisfying a first traction criterion (K1),
i) activating a wheel drive unit; and,
ii) applying a wheel drive torque (M2) to the vehicle wheel to increase the wheel circumferential velocity (v2) and to reduce the wheel slip (s) until a second traction criterion (K2) is satisfied; and,

the wheel drive torque (M2) being changed as a function of the wheel slip (s) with an increase of the wheel drive torque (M2) when there is an increased wheel slip (s) and a reduction of the wheel drive torque (M2) when there is a reduced wheel slip (s).
