Beschreibung
Zusammenfassung:	In a method for ascertaining the coefficient of friction between a vehicle wheel and the roadway, at least one active vehicle unit influencing the longitudinal dynamics of the vehicle is controlled during the trip in such a manner, that the longitudinal wheel force acting upon at least one vehicle wheel is increased, and/or the contact patch force of the wheel is decreased, while the characteristic of the sum of all of the longitudinal forces acting upon the vehicle remains unchanged.
