    Abstract: The present invention relates to a method for determining a friction coefficient value (F?) which represents the coefficient of friction present between the underlying surface and a vehicle tire. For this purpose, a wheel slip value (?ij) is determined for at least one vehicle wheel, said value (?ij) describing the wheel slip present at this vehicle wheel. The friction coefficient value (F?) is determined as a function of this wheel slip value (?ij). For this purpose, during a predefined operating state of the vehicle wheel slip values (?ij) are determined at various times, in particular successive times. The frequency distribution of values is determined for these wheel slip values (?ij) or for axle-related slip values (?VA and ?HA) which are determined as a function of these wheel slip values (?ij). The friction coefficient value (F?) is determined by evaluating this frequency distribution of values.
