PCT No. PCT/EP84/00402 Sec. 371 Date Aug. 16, 1985 Sec. 102(e) Date Aug. 16, 1985 PCT Filed Dec. 15, 1984 PCT Pub. No. WO85/02592 PCT Pub. Date Jun. 20, 1985.A method for ascertaining an optimal slip value lambda at at least one wheel of a vehicle, in order to be able to regulate the braking force optimally. To this end, at least the wheel speed is measured, and the vehicle speed is ascertained. By varying the braking pressure and the slip during driving, signal combinations for the wheel speed, the vehicle speed, the braking pressure and the tire/road contact force are ascertained and inserted into a given function VR(K+1). For the resultant equation system, the coefficients alpha n can then be ascertained from which the coefficients an of a general description of the mu slip curve can be ascertained. With these coefficients an, the mu slip curve and its maximum, from which the optimal slip lambda can then be ascertained, are then clearly defined.
