METHOD FOR DETERMINING A FRICTION COEFFICIENT FOR A CONTACT BETWEEN A TIRE OF A VEHICLE AND A ROADWAY, AND METHOD FOR CONTROLLING A VEHICLE FUNCTION OF A VEHICLE

A method for determining a friction coefficient for a contact between a tire of a vehicle and a roadway. The method includes processing sensor signals in order to generate processed sensor signals. The sensor signals represent state data that are read in at least by at least one detection device and that are correlatable with the friction coefficient. The processed sensor signals represent at least one preliminary friction coefficient. The method also includes ascertaining the friction coefficient using the processed sensor signals and a regression model.
