A friction coefficient between at least one tire of a motor vehicle and a roadway is estimated recursively. A kingpin inclination angle is detected or measured. A model determines a lateral friction value by defining a functional correlation between that value and the angle such that a non-linear course of that value relative to the angle is dependant on an initial increase of that value relative to the angle and on a recursively determined estimated value of the friction coefficient. The initial increase is defined substantially independently from the recursively determined estimated value. In addition, a measurement variable of the driving dynamics is captured. Depending on the lateral friction value, the driving dynamics model variable is determined. Furthermore, a variance between the driving dynamics measurement variable and the driving dynamics model value is determined. The recursion when acquiring the estimated value includes that the estimated value is adjusted.
